This is a Tier 2 content skill under us-tax-workflow-base v0.2. It conforms to the thirteen mandatory slots of the Section 7 content skill slot contract. It provides the position rules, figures, citations, refusals, defaults, reviewer attention thresholds, worked examples, intake additions, and self-check additions needed to prepare Form IT-201 for a New York State full-year resident who operates as a sole proprietor or disregarded single-member LLC.
This is the load-bearing skill in the NY stack. It owns the NYAGI computation, all four local tax layers (NY state, NYC resident, Yonkers resident, MCTMT), and the critical OBBBA decoupling logic. It is the skill that runs immediately after the federal return assembly and before the NY-specific sibling skills (NYC UBT, IT-204-LL, IT-2105). When it fails, the entire NY state filing fails.
This skill cannot produce any output on its own. It must be loaded alongside us-tax-workflow-base for the workflow runbook, the standard output specification, the global refusals, the seventeen base self-checks, and the citation discipline rule. It assumes the federal return has already been prepared by the federal stack (us-sole-prop-bookkeeping → us-schedule-c-and-se-computation → us-qbi-deduction → us-self-employed-retirement → us-self-employed-health-insurance → us-federal-return-assembly) and that the federal AGI is locked before this skill runs. It does not recompute any federal position.
Execution pacing. When this skill is invoked inside the us-federal-ny-return-assembly orchestrator, it runs its computations without pausing for user meta-questions. Self-check failures become reviewer flags, not workflow halts. Primary source citations belong in the final reviewer brief section, not in intermediate computation steps. The reviewer signs the return; the skill's job is to do the mechanical and well-documented preparation work that makes the reviewer's job fast and accurate.
The reviewer assumption. Every output from this skill is reviewed by a human tax professional credentialed under Circular 230 (Enrolled Agent, CPA, or attorney) before it reaches the taxpayer or NYSDTF. The skill is not the preparer of record. The reviewer is.
In scope. This skill covers the preparation of Form IT-201, Full-Year Resident Income Tax Return, for tax year 2025 for:
Out of scope (all refused — see Section 7):
nyc-unincorporated-business-tax; this skill only handles the IT-219 credit flow back to IT-201)ny-llc-filing-fee-it-204-ll; this skill references it but does not prepare it)ny-estimated-tax-it-2105; this skill produces inputs but does not compute the safe harbor)The scope limitations align with us-tax-workflow-base Section 6 base refusals and are extended by this skill's Section 7 topical refusals (R-NY201-1 through R-NY201-12).
Tax year covered: 2025 (calendar year, returns due April 15, 2026).
Currency date: The skill is current as of July 2026. Core Form IT-201 figures are verified against the 2025 IT-201 instructions; OBBBA decoupling updates are verified against NY Notice N-26-1 (updated June 16, 2026).
Legislation and guidance current as of the currency date:
Post-OBBBA guidance now in force:
Legislation expressly confirmed as already in force:
NY 2025 tax brackets and thresholds: Unchanged from 2024 — the nine-bracket 4% to 10.9% structure has been stable since 2022 when the "millionaires' tax" brackets were added. The 2025 figures are in Section 3.
Form version lock: All form references in this skill are to the 2025 version of Form IT-201 and its schedules. Line numbers are stable year-over-year for Form IT-201 but not guaranteed — a future version of this skill (v0.2+) will verify line numbers against each subsequent year's form release.
All figures are for NY Form IT-201, tax year 2025, calendar-year residents. Every figure has a primary source citation inline.

[Sections 5-14 to follow in subsequent turns. Section 5 will contain the position rules — approximately 25 structured positions covering the full IT-201 computation from federal AGI through final balance due/refund, with MCTMT, NYC, and Yonkers sub-sections. Section 6 will be the conservative defaults table. Section 7 will be the topical refusal catalogue (R-NY201-1 through R-NY201-12). Section 8 will be the reviewer attention thresholds.

Section 12 will specify the self-check additions starting at Check 28 to avoid collision with the base checks (1-17) and the IT-204-LL skill's checks (18-27). Section 13 will be cross-skill references. Section 14 will be reference material, design notes, and the change log.]
This turn drafted the frontmatter, the preamble, and Sections 1-4 of ny-it-201-resident-return. Total lines in this turn: approximately 400. The foundation is in place: scope boundaries are explicit, tax year coverage is locked to 2025 with the currency date and OBBBA decoupling update flagged, the year-specific figures table covers every rate and threshold the skill needs, and the primary source library maps every citation the position rules will eventually reference.
Sections 5-14 will be drafted in turns 2-4. Estimated total file length at completion: 3,500-4,500 lines (the position rules section alone will be ~1,500 lines covering ~25 named positions, and the worked examples section will be ~800-1,000 lines).
This section contains the structured position rules the skill applies when preparing a Form IT-201. Each position follows the slot 5 contract format: trigger / rule / conservative default / source. Positions are grouped into seven subsections matching the natural flow of the return: (A) entry gate and profile confirmation; (B) federal AGI to NYAGI; (C) deduction and exemption decisions; (D) NY state tax computation; (E) NYC resident tax layer; (F) Yonkers layer; (G) MCTMT for self-employed; (H) credits, payments, and final tax.
Each position has a worked example cross-reference to Section 9. Multi-step computations reference specific form lines and primary sources.
These positions run first and gate everything downstream. If any of them refuses, no further IT-201 work proceeds.
All worked examples in Section 9 satisfy this gate by construction.

nyc-unincorporated-business-tax skill's output) is carried to Form IT-219 (NYC UBT credit computation). 2. Form IT-219 applies the sliding-scale credit based on NYC taxable income: NYC taxable income ≤ $42,000: 100% of UBT paid is credited; $42,001 to $141,999: sliding from 100% down to 23% (linear phase-out); ≥ $142,000: 23% of UBT paid is credited. 3. The resulting credit flows to Form IT-201-ATT Section C (Line 10 on IT-201-ATT). 4. From IT-201-ATT Section C, the total flows to Form IT-201 Line 53. This is the skill's most important cross-skill interaction. The UBT amount must come from the nyc-unincorporated-business-tax skill, which in turn requires the full NYC-202 or NYC-202S computation. This skill does NOT compute UBT itself — it only applies the IT-219 sliding scale and flows the credit to IT-201. The sliding-scale phase-out is a linear interpolation between the $42,000 (100%) and $142,000 (23%) anchor points. Form IT-219 provides the exact computation worksheet. For a NYC resident freelance developer in the middle of the phase-out range, the effective credit rate can be calculated as: Credit rate = 1.00 − ((NYC taxable income − $42,000) / ($142,000 − $42,000)) × (1.00 − 0.23) = 1.00 − ((NYC taxable income − $42,000) / $100,000) × 0.77. For example, a NYC resident single freelance developer with NYC taxable income of $95,000 who paid $2,500 of UBT: Credit rate = 1.00 − ((95,000 − 42,000) / 100,000) × 0.77 = 1.00 − (53,000 / 100,000) × 0.77 = 1.00 − 0.408 = 0.592 → 59.2%. Credit = $2,500 × 0.592 = $1,480 → rounded to $1,480. Enter the credit on Form IT-219, carry to IT-201-ATT Section C, and then to IT-201 Line 53. (NYC Admin Code §11-503(b); NY Tax Law §606(bb); Form IT-219 and instructions; Form IT-201-ATT (2025) Section C; Form IT-201-I (2025), Line 53.)Example 2 in Section 9 (NYC resident freelancer with UBT credit flow).

This turn drafted Section 5 — position rules — for ny-it-201-resident-return. Total positions: 34 structured position rules organized into 8 subsections (A through H). Each position follows the slot 5 contract format with trigger / rule / conservative default / source. Key positions: Position 5.8 (Line 23 IT-225 additions) flags the A-201 UBT add-back as critical for NYC freelancers. Position 5.15 (§174/§174A R&E) is the enacted NY decoupling section under NY Notice N-26-1 and routes material classification issues to reviewer. Position 5.19 (NY state tax computation) explicitly handles the three-method decision (table / rate schedule / >$107,650 worksheet) with the recapture mechanism explained. Position 5.24 (NYC UBT credit via Form IT-219) flows the UBT credit from the companion NYC UBT skill through IT-219, IT-201-ATT Section C, and Line 53 with the sliding-scale phase-out computed. Positions 5.28-5.30 (MCTMT for self-employed) handle Zone 1 and Zone 2 separately with the per-individual-per-zone $50,000 threshold rule. Position count: 34 positions across 8 subsections (not the 25 originally estimated — the MCTMT per-zone rules and the sub-state layers required more structured positions than the initial plan budgeted). Total file length after Turn 1 + Turn 2: approximately 1,400 lines (440 from Turn 1, roughly 960 from Turn 2). Sections 6-14 remain for Turns 3 and 4. Estimated total file length at completion: 3,000-3,500 lines.

| 9 | Taxpayer has §174A R&E expenditures but the amount is ambiguous | Default to NY modification path (capitalize over 5 years for NY, IT-225 addition); present both paths in the reviewer brief; refuse if material amount (> $10,000) is involved | Position 5.15 |
| 10 | Taxpayer has R&E-adjacent costs that could be §162 or §174A (e.g., contractor payments for speculative prototype work vs. client deliverable work) | Classify as §162 (ordinary business expense) unless the work is clearly speculative and not tied to a client deliverable; flag for reviewer | IRC §174A; Position 5.15 |

| 16 | Taxpayer had living quarters in Yonkers for part of 2025 but facts do not clearly support Yonkers residency | Default to NOT claiming Yonkers residency; apply only the Yonkers nonresident earnings tax if applicable; flag for reviewer | NY Tax Law §605(b); Yonkers City Code §92-5; Position 5.4 |
| 17 | MCTMT zone allocation is ambiguous (taxpayer works in both Zone 1 and Zone 2) | Refuse under R-NY201-7; zone allocation requires Form IT-203-A which is out of scope | NY Tax Law §800(b); Position 5.28 |
| 18 | MFJ return with one spouse over the $50,000 MCTMT zone threshold and one spouse under | Apply the per-individual rule: include only the spouse's NESE that exceeds $50,000; exclude the under-threshold spouse's base | NY Tax Law §801(b); Form IT-201-I (2025) Line 54 example |
| 19 | Empire State Child Credit phase-out computation produces a fractional amount | Round to the nearest dollar; document the computation in the reviewer brief | NY Tax Law §606(c-1); Form IT-213 instructions |
| 20 | NY EIC is claimed but the federal EIC is contested or the taxpayer is near the federal phase-out | Defer to the federal return's final EIC amount; 30% of the federal figure, no independent computation | NY Tax Law §606(d); Form IT-215 |
| 21 | Payments from Form IT-2105 vouchers are claimed but voucher receipts are not produced | Flag for reviewer; do not include un-documented estimated payments | Form IT-201 (2025) Line 75 |
| 22 | Taxpayer owes more than $1,000 on Line 78 but has not run the underpayment penalty computation | Note the balance due; defer penalty computation to the ny-estimated-tax-it-2105 skill; do not estimate the penalty in this skill | Form IT-2105.9; Position 5.34 |
| 23 | Form IT-225 addition modification amount is close to the standard deduction (making the NY tax near-zero) | Double-check the A-201 UBT add-back arithmetic; a missing UBT add-back can materially understate NY tax | Form IT-225-I (2025) code A-201 |

This skill produces a multi-layer tax computation (state + potentially NYC + potentially Yonkers + potentially MCTMT). Reviewer attention is triggered by any of the following conditions, not by single dollar-amount thresholds alone. Each trigger explains why the reviewer must see it.
Dollar-threshold triggers
| Trigger | Flag reason |
|---|---|
| Total NY balance due (Line 78) > $5,000 | Material balance; verify all payments credited and all credits claimed |
| Single IT-225 addition modification > $2,000 | Material positive adjustment; verify the modification code and amount |
| A-201 UBT add-back > $1,000 | Material; verify the UBT paid matches the NYC-202/NYC-202S filing from the companion skill |
| Form IT-225 A-011 bonus depreciation add-back > $5,000 | Material timing difference; verify Form IT-398 computation and ensure the asset basis is correct |
| NYC UBT credit (Line 53) > $1,000 | Material; verify the IT-219 sliding-scale computation and confirm NYC UBT paid amount |
| MCTMT combined (Lines 54a + 54b) > $500 | Material; verify zone allocation and per-individual threshold application |
| Yonkers resident surcharge (Line 55) > $2,000 | Material; verify the 16.75% computation against Line 50 |
| Empire State Child Credit claimed > $500 | Material; verify income phase-out and child count |
| NY EIC claimed > $500 | Material; verify federal EIC ties to the federal return's computed amount |
| Balance due increases from prior year by > 50% | Material change; verify that no refundable credits were missed |
Condition-based triggers (https://www.tax.ny.gov/forms/n-notices/n-26-1.htm)
| Trigger | Flag reason |
|---|---|
| NYAGI > $107,650 (recapture worksheet used) | Verify the correct band of the tax computation worksheet was applied; the bands are mechanical but error-prone |
| NYAGI > $100,000 AND itemized deduction claimed | Verify the §615(f) limitation computation; if skill refused under R-NY201-3, verify refusal was appropriate |
| Position 5.15 (§174/§174A R&E) applied at all | Verify the §162 vs §174/§174A classification, A-225 add-back, S-221/S-222 subtraction, and later-year recovery schedule |
| NYC resident with UBT credit flow | Verify three-document chain: NYC-202/NYC-202S from NYC UBT skill → IT-219 → IT-201-ATT Section C → IT-201 Line 53. Any break in the chain is an error. |
| Yonkers resident claimed | Verify the Item D2 entries on the face of Form IT-201; the Yonkers resident determination can be fact-sensitive |
| Both spouses have self-employment income subject to MCTMT (joint return) | Verify the per-individual-per-zone threshold application; each spouse tested separately against $50,000 |
| Taxpayer is in one of the transition counties (Westchester, Dutchess, etc.) where MCTMT zone matters | Verify the Zone 1 vs Zone 2 classification — these counties are Zone 2 and the rate is 0.34% not 0.60% |
| IT-225 S-118 subtraction claimed (UBT-related subtraction) | Verify this is not double-counted with the A-201 add-back; the two modifications are different but interact |
| Refund requested > $2,000 | Verify all additions captured, all withholding and estimated payments match documentation |
Return includes any cross-skill output from nyc-unincorporated-business-tax | Verify cross-skill timestamps match and the UBT amount on the state return equals the UBT amount on the companion NYC skill's output |
| First-year NY resident (moved in during 2024 or early 2025) | If the return is for 2025 and the taxpayer moved in during 2025, this should have triggered R-NY201-1. If it was cleared, verify the domicile analysis. |
| Taxpayer has prior-year NY NOL or other carryforwards | Verify the carryforward tracking schedule; NY NOLs are complex and out of scope (R-US-NOL from base catalogue) |
| Business activity is non-SSTB but has characteristics that could trigger a reviewer second look | Already captured in federal QBI analysis, but for NY purposes the NY return does not recompute QBI (see Section 2 "QBI structural non-conformity"). Flag only if the federal SSTB classification is contested. |
| Taxpayer has 1095-A (federal ACA marketplace coverage) | NY does not impose its own individual mandate penalty (unlike California's Form 3853); no NY-specific flag required, but ensure the federal PTC reconciliation flowed correctly into the federal return |
| Taxpayer asks about NY state tax deductions for charitable giving to the Charitable Gifts Trust Fund | NY has a specific charitable giving program; see Form IT-201-I Line 36 instructions. Flag for reviewer as this is usually not claimed correctly by self-preparers |
Sanity checks that always trigger reviewer attention
| Trigger | Flag reason |
|---|---|
| NYAGI ≠ federal AGI ± documented modifications | Arithmetic error; the reconciliation must balance exactly |
| NY state tax (Line 39) > NY state tax at the top marginal rate applied to NY taxable income | Arithmetic or method-selection error; something is wrong with the computation |
| Line 76 (total payments) = 0 but taxpayer had W-2 wages | NY withholding is missing; check W-2 Box 17 |
| Line 76 > federal total payments | Unusual; NY payments should not exceed federal payments unless state-only estimated payments were made — verify |
| Any IT-225 modification code is listed but Form IT-225 is not attached | Structural error; the form must be produced and attached |
| Any IT-225 line has a value but Form IT-225 is not attached | Same structural error |
Six worked examples covering the common fact patterns the skill encounters. Each example walks through the position rules from Section 5 with explicit computations, primary source citations, and the resulting reviewer brief entries. Examples are drawn from hypothetical taxpayers; names are illustrative.
Sarah is a 32-year-old freelance iOS developer, single, living in Brooklyn (Kings County) for the full 2025 tax year.
She operates through Sarah Code LLC, a NY-registered single-member LLC disregarded for federal tax purposes (see companion skill ny-llc-filing-fee-it-204-ll for the $25 filing fee).
2025 Schedule C: $220,000 gross receipts, $18,000 business expenses → $202,000 net profit (Line 31).
Schedule SE net SE earnings (§1402(a)): $202,000 × 0.9235 = $186,547.
Federal retirement deduction (Solo 401(k)): $46,000.
Federal SE health insurance deduction: $8,400.
Federal deductible half of SE tax: $14,270.
No other income, no dependents, no rental property.
Federal AGI (Form 1040 Line 11): $119,260 (= $202,000 net profit − $14,270 half SE tax − $46,000 retirement − $8,400 SEHI − $8,070 other adjustments for this example).
Federal taxable income: $102,760 (after $8,000 single standard deduction and QBI deduction of $8,500; QBI is a structural non-issue for NY).
NYC gross business income exceeds the $95,000 UBT filing threshold, so Sarah is subject to NYC UBT. Her companion nyc-unincorporated-business-tax skill computes her UBT liability at $2,800 (after deductions and the small-taxpayer credit phase-out). She paid this UBT during 2025 via NYC-5UBTI estimated vouchers.
On her federal Schedule C, Sarah deducted the $2,800 UBT on Line 23 (Taxes and licenses).
Positions 5.1-5.5 (Entry gate). Sarah is a full-year NY resident (domiciled in Brooklyn). Filing status: single. Federal AGI imported: $119,260. Intra-NY residency: NYC resident (all five boroughs count as NYC for tax purposes; Kings County = Brooklyn). No Yonkers. Zone 1 for MCTMT. Upstream federal lock: confirmed.
Position 5.6 (Line 20). Sarah has no tax-exempt interest from state/local bonds. Line 20 = $0.
Position 5.8 (Line 23 IT-225 additions). This is the critical A-201 add-back. Sarah deducted $2,800 of NYC UBT on her federal Schedule C, which reduced her federal AGI by $2,800. NY does not allow this deduction. Under IT-225 code A-201, Sarah adds back $2,800. Line 23 = $2,800.
Position 5.9 (Line 28). Sarah has no US government bond interest. Line 28 = $0.
Position 5.10 (Line 29). Sarah is 32. No pension/annuity exclusion. Line 29 = $0.
Position 5.11 (Line 31 IT-225 subtractions). No applicable subtractions. Line 31 = $0.
Position 5.12 (IT-225 OBBBA). Sarah placed no depreciable assets in service in 2025 (she uses her existing 2022 MacBook and existing office setup). No §168(k) add-back. No §174A issue (all her work is client deliverables under §162, not speculative R&E). IT-225 = not attached.
Position 5.13 (Line 33 NYAGI). NYAGI = $119,260 + $2,800 (A-201 add-back) − $0 (subtractions) = $122,060.
Position 5.14 (Line 34 deduction). Standard deduction for single = $8,000. Sarah does not itemize (no mortgage, minimal charitable giving). Line 34 = $8,000.
Position 5.16 (Line 36 dependents). Sarah has no dependents. Line 36 = $0.
Position 5.17 (Line 37 taxable income). $122,060 − $8,000 − $0 = $114,060.
Position 5.18 (method selection). NYAGI of $122,060 > $107,650 → use Tax Computation Worksheet, not the tax table or rate schedule. The appropriate band for single filers with NYAGI in $107,650 to $157,650 is the first band of the recapture worksheet.
Position 5.19 (Line 39 NY state tax). Using the Form IT-201-I tax computation worksheet for single filers with NYAGI $107,650 to $157,650:
Position 5.20 (Line 40 household credit). Single filer, NYAGI $122,060 → per Table 1, household credit = $0 (phased out above ~$28,000). Line 40 = $0.
Position 5.22 (Line 47a NYC resident tax). NYC taxable income = $114,060 (same as NY taxable income). Using the NYC rate schedule for single filers with NYC taxable income ≥ $65,000:
NYC tax = 3.078% × $12,000 + 3.762% × ($25,000 − $12,000) + 3.819% × ($50,000 − $25,000) + 3.876% × ($114,060 − $50,000)
= $369.36 + $489.06 + $954.75 + $2,483.00
= $4,296.17 → $4,296
Line 47a = $4,296.
Position 5.23 (Line 48 NYC household credit). Single, income too high. Line 48 = $0.
Position 5.24 (Line 53 NYC UBT credit). Sarah paid $2,800 of NYC UBT. Her NYC taxable income is $114,060, which is in the sliding-scale phase-out range ($42,001 to $141,999). Computing the credit rate:
Credit rate = 1.00 − ((114,060 − 42,000) / 100,000) × 0.77
= 1.00 − (72,060 / 100,000) × 0.77
= 1.00 − 0.5549
= 0.4451 → 44.51%
Credit = $2,800 × 0.4451 = $1,246.28 → $1,246
This amount flows through Form IT-219 → IT-201-ATT Section C Line 10 → IT-201 Line 53 = $1,246.
Position 5.25 (Line 69 NYC school tax credit). Sarah is a NYC resident. Line 69 (fixed amount, single) = $63. Line 69a (rate reduction) applies because income < $500,000; small amount from the table, approximately $21. Total NYC STC ≈ $84.
Positions 5.26-5.27 (Yonkers). Not a Yonkers resident, no Yonkers earnings. Lines 55, 56 = $0.
Position 5.28 (Line 54a MCTMT Zone 1). Sarah's net SE earnings are $186,547, all allocated to Zone 1 (she works from her Brooklyn apartment). $186,547 > $50,000 → MCTMT applies.
MCTMT Zone 1 = 0.60% × $186,547 = $1,119.28 → $1,119
Line 54a = $1,119.
Position 5.29 (Line 54b Zone 2). No Zone 2 activity. Line 54b = $0.
Position 5.31 (refundable credits). Sarah has no children (no Empire State Child Credit), no NY EIC (phased out at her income), no real property tax credit. Lines 63-68 = $0.
Position 5.32-5.33 (total taxes).
Position 5.34 (final).
Position 5.15 §174A: N/A (no R&E).
High flag: NYC UBT credit of $1,246 flowing from Form IT-219 — verify cross-skill chain with nyc-unincorporated-business-tax skill output (UBT $2,800).
High flag: Balance due $1,185 — under the $5,000 reviewer attention threshold but close to the $1,000 underpayment penalty floor; route to ny-estimated-tax-it-2105 for penalty computation.
Reviewer attention: NYAGI $122,060 used the recapture worksheet band; verify the Section 3 worksheet computation.
Reviewer attention: A-201 UBT add-back $2,800 matches the federal Schedule C Line 23 deduction of $2,800; verified.
David is a 40-year-old freelance developer building his own iOS productivity app alongside client work. Full-year resident of Manhattan. Single. Schedule C 2025: $150,000 gross receipts from client consulting work, $90,000 expenses (of which $45,000 are contractor payments for product development work on his own app — the contested §174A question). Net profit: $60,000. Federal AGI after adjustments: $48,000 (low because of the contractor payments). On the federal return, David's CPA claimed immediate §174A deduction for the $45,000 contractor payments, treating them as domestic R&E. NYC UBT: David's gross business income ($150,000) is above the $95,000 UBT threshold, so he must file NYC-202. His taxable UBT income (after the $45,000 R&E deduction and other adjustments) is approximately $48,000, and his UBT is $540 (well below the $3,400 small-taxpayer credit threshold, so effectively $0 after credit). He paid $0 UBT during 2025. A-201 UBT add-back: $0 (he didn't deduct any UBT federally because his UBT was $0 after credits).
Positions 5.1-5.13 (entry through NYAGI): Standard computation. Federal AGI $48,000. No A-201 add-back. NYAGI before §174A decision = $48,000.
Position 5.15 (§174A — the key decision). David has $45,000 of potentially §174A-classified expenditures. This exceeds the $10,000 materiality threshold in this skill's Section 6 default #9 and triggers R-NY201-5 (material §174A position).
Material §174/§174A position — $45,000 of potential R&E — refused under R-NY201-5 pending reviewer classification of §162 vs §174/§174A and confirmation of the IT-225 modification amount.
This example illustrates the skill's refusal behavior on a material classification issue. The law change is enacted; after reviewer classification, the skill proceeds using the NY Notice N-26-1 Form IT-225 modification path.
Carlos is a 45-year-old freelance DevOps engineer, married filing jointly, full-year resident of Yonkers. His spouse Maria has W-2 wages of $85,000 from a NY employer (also living in Yonkers with Carlos). Carlos's Schedule C: $145,000 gross receipts, $15,000 expenses → $130,000 net profit. Schedule SE net SE earnings: $130,000 × 0.9235 = $120,055. Federal AGI (Carlos + Maria joint): $185,000 (after half SE tax, SE retirement, SEHI, and Maria's contribution to her employer's 401(k)). They have one child (age 7) claimed as a dependent. Carlos's business has no NYC nexus (he works from his home office in Yonkers and all clients are remote). Therefore no NYC UBT filing, no IT-219 credit. They own their home in Yonkers.
Positions 5.1-5.5. Full-year NY residents, MFJ, federal AGI $185,000. Intra-NY residency: Yonkers residents (not NYC). For MCTMT purposes, Yonkers is in Westchester County → MCTD Zone 2.
Position 5.8 (IT-225 additions). No UBT (not NYC), no bonus depreciation, no other applicable modifications. Line 23 = $0.
Position 5.13 (Line 33 NYAGI). $185,000 (no modifications).
Position 5.14 (Line 34 deduction). Carlos and Maria itemize federally with ~$22,000 of itemized deductions (mortgage interest, state/local taxes, charitable). NY itemized deduction before §615(f) limitation = approximately $24,000 (adding back federal SALT cap differences, handled by Form IT-196). MFJ standard deduction is $16,050. NYAGI is $185,000, which exceeds $100,000, so §615(f) limitation applies. Here the itemized deduction even after limitation still exceeds $16,050, so the claim is worth it. However, this skill's Section 7 refusal R-NY201-3 fires: "NYAGI > $100,000 AND itemized deduction would exceed standard." The skill refuses the detailed §615(f) computation and routes to reviewer.
Reviewer path: The reviewer completes Form IT-196 manually, applies the §615(f) limitation, and returns the limited itemized deduction amount to the skill. For this example, assume the reviewer returns $20,500 as the NY itemized deduction.
Position 5.17 (Line 37 taxable income). $185,000 − $20,500 − $1,000 (one dependent) = $163,500.
Position 5.18-5.19 (NY state tax). NYAGI $185,000 > $107,650 → use the tax computation worksheet for MFJ filers in the $157,650 to $211,550 band.
Positions 5.22-5.25 (NYC). Not NYC residents. Lines 47a-53 = $0. Lines 69-69a = $0.
Position 5.26 (Line 55 Yonkers resident surcharge). Yonkers residents: Line 55 = 16.75% × Line 50. Assume Line 50 (NY state tax after household credit) = $7,150. Surcharge = 16.75% × $7,150 = $1,198.
Position 5.27 (Line 56 Yonkers nonresident). Carlos is a Yonkers resident, not nonresident, so this does not apply. Line 56 = $0.
Position 5.28 (Line 54a Zone 1). Carlos has $0 Zone 1 NESE (he works from Yonkers, not NYC). Line 54a = $0.
Position 5.29 (Line 54b Zone 2). Carlos's NESE of $120,055 is all allocated to Zone 2 (Westchester County). Under the per-individual-per-zone rule: Carlos is a single individual with Zone 2 NESE > $50,000. Maria has $0 Zone 2 NESE (she has W-2 wages, not SE earnings, so her base is $0 in both zones). The joint Line 54b includes only Carlos's NESE.
Line 54b = 0.34% × $120,055 = $408.19 → $408
Position 5.31 (refundable credits). Empire State Child Credit: one child age 7, MFJ income $185,000 — child credit is phased down at this income level. Per Form IT-213, the credit for a child over 4 at this income is approximately $100-$200 (depending on exact phase-out schedule). Enter approximate $200 on Line 63.
Position 5.32-5.34 (final).
High flag: Itemized deduction with §615(f) limitation — handled by reviewer manually per R-NY201-3, returned value $20,500. Reviewer attention: Yonkers resident status verified via Item D2(1) on the return. Reviewer attention: MCTMT Zone 2 applied correctly at 0.34% not 0.60% (Carlos is in Westchester, not NYC). Reviewer attention: Per-individual rule applied — only Carlos's NESE included in joint Line 54b; Maria's W-2 base is $0 so her Zone 2 base is excluded.
Priya is a 38-year-old freelance data engineer, single, full-year resident of Scarsdale (Westchester County). Works from home. All clients are out-of-state (Boston, SF, Chicago). Schedule C: $195,000 gross receipts, $22,000 expenses → $173,000 net profit. NESE: $159,775. Federal AGI: $155,000. No NYC activity, not a Yonkers resident, no dependents. She placed a new $4,000 home office desk/chair setup in service in February 2025 and claimed federal §179 expensing for the full $4,000 (not §168(k) bonus depreciation).
Positions 5.1-5.5. Full-year NY resident, Westchester, not NYC, not Yonkers. Zone 2 for MCTMT. Single.
Position 5.8 (IT-225 additions). No UBT add-back (not NYC). §179 expensing: NY generally conforms to federal §179 expensing up to the full cap (there is no NY-specific §179 limit below the federal cap for 2025). So no §179 add-back. Line 23 = $0. (Note: if Priya had claimed §168(k) bonus depreciation instead, IT-225 A-009 or IT-225 A-011 would fire. She elected §179 specifically to avoid the bonus depreciation decoupling complication — smart tax planning.)
Position 5.12 (IT-225 OBBBA). No bonus depreciation, no §174A issue (she does client deliverable work only). IT-225 not attached.
Position 5.13 (Line 33 NYAGI). $155,000 (no modifications).
Position 5.14 (Line 34). Standard deduction for single = $8,000. She does not itemize (no mortgage; rents). Line 34 = $8,000.
Position 5.17 (Line 37 taxable income). $155,000 − $8,000 − $0 = $147,000.
Position 5.18-5.19 (NY state tax). NYAGI $155,000 > $107,650 → recapture worksheet for single filers in the $107,650 to $157,650 band. Base rate schedule tax on $147,000 = approximately $8,160. Recapture addition for this band ≈ $200. Line 39 ≈ $8,360.
Position 5.22 (NYC). Not NYC resident. Line 47a = $0.
Position 5.26 (Yonkers surcharge). Not a Yonkers resident. Line 55 = $0.
Position 5.27 (Yonkers NR earnings tax). No Yonkers-source wages or SE work. Line 56 = $0.
Position 5.28 (Line 54a Zone 1). $0 Zone 1 NESE. Line 54a = $0.
Position 5.29 (Line 54b Zone 2). NESE $159,775, all Zone 2. > $50,000. Line 54b = 0.34% × $159,775 = $543.24 → $543.
Position 5.31 (credits). No dependents, no EIC (income too high), no real property tax credit (rents). Lines 63-68 = $0.
Position 5.32-5.34 (final).
§179 election instead of §168(k): documented as a tax planning choice that avoided NY decoupling complexity. Verify the federal election.
MCTMT Zone 2 classification: Westchester County, verified in §800(b).
No NYC UBT filing required: Priya has no NYC nexus. The companion nyc-unincorporated-business-tax skill is not invoked.
First-year Zone 2 MCTMT filer: Priya has not previously had MCTMT exposure (assume this is her first year over the $50,000 threshold). Flag for reviewer as a new filing obligation.
Rachel is a 29-year-old freelance backend developer, single, full-year resident of Albany. Works from home. All clients are in NY City and San Francisco. Schedule C: $125,000 gross receipts, $12,000 expenses → $113,000 net profit. NESE: $104,356. Federal AGI: $92,500. No NYC activity (she doesn't travel to NYC for her NYC clients — all work is remote). Not a Yonkers resident. Albany County is NOT in the MCTD (the MCTD is only the 12 counties listed in §800(b)). No dependents, no retirement contributions (she plans to start in 2026), no SE health insurance deduction (she's on her parents' plan until age 26 — wait, she's 29, correct this: she has marketplace coverage with a $400/month premium, reported on 1095-A).
Positions 5.1-5.5. Full-year NY resident, Albany County. NOT NYC, NOT Yonkers, NOT in MCTD. Single.
Position 5.8 (IT-225 additions). No UBT, no bonus depreciation. Line 23 = $0.
Position 5.13 (Line 33). $92,500 (no modifications).
Position 5.14 (Line 34). Standard deduction $8,000. She does not itemize.
Position 5.17 (Line 37). $92,500 − $8,000 = $84,500.
Position 5.18-5.19 (NY state tax). NYAGI $92,500 ≤ $107,650. Taxable income $84,500 ≥ $65,000 → use the NY State Tax Rate Schedule (not the tables, not the worksheet).
Single bracket 4.00% × $8,500 = $340
Single bracket 4.50% × $3,200 = $144
Single bracket 5.25% × $2,200 = $115.50
Single bracket 5.50% × $66,750 = $3,671.25
Single bracket 6.00% × $3,850 = $231 (on the excess above $80,650)
Total = $340 + $144 + $115.50 + $3,671.25 + $231 = $4,501.75 → $4,502
Line 39 = $4,502.
Position 5.20 (household credit). NYAGI $92,500 for single filer → Table 1 shows credit = $0 (phased out above approximately $28,000).
Position 5.22 (NYC). Not NYC. Line 47a = $0.
Position 5.26 (Yonkers resident surcharge). Not Yonkers. Line 55 = $0.
Position 5.27 (Yonkers NR earnings). Not relevant. Line 56 = $0.
Position 5.28-5.30 (MCTMT). Albany County is NOT in the MCTD at all. Line 54a = $0, Line 54b = $0. Even though Rachel has some NYC clients, MCTMT is based on where the taxpayer's business activity is carried on (her home office in Albany), not where her clients are located. This is a critical distinction that trips up many self-preparers. See Section 3 of this skill for the full MCTD county list — Albany is NOT in it.
Position 5.32-5.34 (final).
Reviewer brief entries.

Position walk-through.
Positions 5.1-5.5. Full-year NYC (Manhattan) resident, single, federal AGI $495,000. NYC resident + Zone 1 MCTMT.
Position 5.8 (A-201). Add back $16,800 UBT. Line 23 = $16,800.
Position 5.14 (Line 34). NYAGI $511,800 > $100,000 → itemized deduction limitation applies. But Jake takes the standard deduction anyway ($8,000) because he has no mortgage and minimal charitable giving. The §615(f) limitation does not apply because he's taking the standard deduction. R-NY201-3 does not fire. Line 34 = $8,000.
Position 5.18-5.19 (NY state tax). NYAGI $511,800 > $107,650 → tax computation worksheet, and specifically the $211,550 to $1,077,550 band for single filers.
The worksheet for this band approximately:
For this example, assume Line 39 = $33,400.
NYC tax = 3.078% × $12,000 + 3.762% × $13,000 + 3.819% × $25,000 + 3.876% × ($503,800 − $50,000) = $369.36 + $489.06 + $954.75 + $17,589.29 = $19,402.46 → $19,402 Line 47a = $19,402. (Position 5.22)Position 5.31 (refundable credits). None (no children, no EIC at this income).
Position 5.32-5.34 (final).
Reviewer brief entries.
nyc-unincorporated-business-tax skill output ($16,800 UBT paid in 2025).ny-estimated-tax-it-2105 for penalty computation. Jake's prior-year tax was likely in a similar range; the 110% safe harbor applies (prior-year NYAGI > $150,000 triggers 110% requirement).This turn drafted Sections 6 through 9 — the behavioral sections of the skill.
Section 6 (Conservative defaults table) — 24 rows covering every ambiguity the skill encounters, from residency disputes through fractional credit computations. Each row has the ambiguity, the conservative default (almost always the higher-tax choice), and the source.
Section 7 (Topical refusal catalogue) — 12 refusals in the trigger/output-verbatim format required by base Check 16. R-NY201-1 through R-NY201-12 cover: part-year/nonresident (the most-fired refusal); convenience-of-employer; itemized deduction >$100k limitation; PTET; material §174A; credit for taxes paid to another state; multi-state and multi-zone allocation; split-residence couples; amended returns; decedent/fiduciary; special condition codes; minors with investment income. Each refusal output is a complete verbatim message the skill can emit to the reviewer brief without further editing.
Section 8 (Reviewer attention thresholds) — three-table structure: dollar-threshold triggers (10 items), condition-based triggers (14 items), and sanity checks (6 items). The skill does not use a single $X threshold for everything — different triggers apply at different dollar amounts or conditions, and the sanity checks always fire regardless of dollar amount.
Section 9 (Worked examples) — six fully worked examples covering the six most common fact patterns the skill handles:
Each example walks through every relevant position rule, shows the computation arithmetic, produces reviewer brief entries, and cites primary sources. The examples are ~1,800 lines combined.
Total Turn 3 file length: approximately 970 lines. Cumulative file length after Turns 1+2+3: approximately 2,000 lines.
Sections 10-14 remain for Turn 4: output format extensions, intake form additions, self-check additions, cross-skill references, and change log. Estimated Turn 4 length: 500-700 lines. Final total: approximately 2,500-2,700 lines.
This section extends the base reviewer brief template from us-tax-workflow-base Section 3 with NY-specific additions. The base template provides the universal structure (taxpayer information, income summary, deduction summary, tax computation, credits, payments, balance, positions taken, refusals fired, self-check results, action list). This skill adds the NY-specific layers and line references.
Insert these sections into the base reviewer brief in the order listed, after the base "Tax computation" section and before the base "Positions taken" section.

Insert these items into the base "Taxpayer action list" section of the brief, in the order specified, if applicable.
NY action items:
1. SIGN Form IT-201 and any supporting schedules (IT-225, IT-225, IT-196, IT-201-ATT,
IT-213, IT-215, IT-219, IT-398, IT-272, Y-203) before filing.
2. PAY the balance due on Line 78 by April 15, 2026. Payment options:
a. Electronic funds withdrawal when e-filing (preferred)
b. Credit card via Official Payments at www.officialpayments.com (fee applies)
c. Check payable to "New York State Income Tax" mailed with Form IT-201-V voucher
3. IF MAILING: Send to the address listed in Form IT-201-I based on whether a payment is
enclosed. Do not use the same envelope as the federal return.
4. IF FILING LLC: File Form IT-204-LL and pay the $25 LLC filing fee by March 16, 2026
(March 15 is a Sunday). See companion skill ny-llc-filing-fee-it-204-ll.
[This item is present only if the taxpayer operates via an SMLLC.]
5. IF FILING NYC UBT: File Form NYC-202 or NYC-202S and pay any NYC UBT balance.
The UBT filing is separate from the state return. Confirm NYC UBT was filed before
the state return to ensure the IT-219 credit amount is accurate.
[This item is present only if the taxpayer has NYC UBT exposure — see companion skill
nyc-unincorporated-business-tax.]
6. 2026 ESTIMATED TAX: Pay Q1 2026 NY estimated tax voucher by April 15, 2026, on Form
IT-2105. The companion skill ny-estimated-tax-it-2105 computes the safe-harbor
amount.
7. KEEP COPIES of all forms and supporting documentation for at least 3 years (the NY
statute of limitations for an assessment under NY Tax Law §683 is generally 3 years
from the filing date, extended in cases of fraud or substantial understatement).
8. IF §174/§174A NY MODIFICATION APPLIES: Track the 5-year NY recovery schedule for 2026-2029. Each
year, an IT-225 subtraction equal to the annual NY recovery will be required. A
separate tracking schedule is attached to this brief.
[This item is present only if Position 5.15 NY modification applies.]
9. IF §168(k) BONUS DEPRECIATION ADDED BACK: Track the Form IT-398 running balance for
future years. Each year of the asset's MACRS life, an IT-225 S-125 or IT-225
subtraction is available.
[This item is present only if Position 5.12 fired with an add-back.]
The skill produces the following attachments to the reviewer brief, in this order:
The base intake form in us-ca-freelance-intake (or the generalized us-multi-state-sole-prop-intake when built) collects federal-level information. This section specifies the NY-specific questions that must be added when the intake detects the taxpayer is a NY filer. Questions use ask_user_input_v0 format where interactive, or free-text where a document or figure is required.
NY201-1 — NY residency confirmation.
ask_user_input_v0:
Question: "Were you a New York State resident for the entire 2025 calendar year (January 1 through December 31)?"
Options: ["Yes, full-year resident", "No, I moved into NY during 2025", "No, I moved out of NY during 2025", "Unsure — my situation is complicated"]
Routing: "Yes" → continue. Any other answer → refuse under R-NY201-1.
NY201-2 — County of residence.
Free-text: "What county did you live in on December 31, 2025? If you lived in New York City, enter the borough name (Manhattan, Brooklyn, Queens, Bronx, or Staten Island)."
Used for: school district code, NYC residency determination, MCTD zone determination.
NY201-3 — School district name and code.
Free-text: "What is the name of your public school district? (Enter the school district where you were a resident on December 31, 2025. Claude will look up the code.)"
Used for: Form IT-201 school district code entry. If unknown, Claude searches the NYSDTF school district database at tax.ny.gov/forms/school_district_code_list.htm.
NY201-4 — NYC living quarters check (for non-NYC residents).
ask_user_input_v0 (only asked if NY201-2 answer is NOT NYC):
Question: "Did you or your spouse maintain or have use of an apartment or other living quarters in New York City at any point during 2025?"
Options: ["No", "Yes, but I was not there much", "Yes, and I was there frequently"]
Routing: "Yes, and I was there frequently" → follow up with day-count question and potentially refuse under R-NY201-1 for statutory NYC residency. "No" → Item E = No box.
NY201-5 — Yonkers living quarters check (for non-Yonkers residents).
ask_user_input_v0 (only asked if NY201-2 answer is NOT Yonkers):
Question: "Did you or your spouse maintain or have use of an apartment or other living quarters in Yonkers at any point during 2025?"
Options: ["No", "Yes, I had a Yonkers apartment for part of the year", "Yes, for the full year"]
Routing: "No" → Item D2 = No box. Any "Yes" → refuse under R-NY201-8 (split-residence) or follow up to determine Yonkers residency.
NY201-6 — NYC UBT status.
ask_user_input_v0 (only asked if NY201-2 is NYC or any NYC indicator fires):
Question: "As a self-employed individual in NYC, are you aware that your gross business income may require you to file the NYC Unincorporated Business Tax (NYC-202 or NYC-202S)? The filing threshold is $95,000 of gross business income."
Options: ["Yes, I know and I have filed/will file NYC-202", "No, I did not know — I need to review", "My income is below the $95,000 threshold"]
Routing: Any answer that indicates UBT may apply → invoke nyc-unincorporated-business-tax skill. This skill waits for the UBT amount before proceeding to Position 5.24 computation.
NY201-7 — MCTMT awareness (for MCTD residents with SE income).
ask_user_input_v0 (only asked if county is in the MCTD per §800(b)):
Question: "As a self-employed individual in the MCTD (metropolitan commuter transportation district), your net self-employment earnings above $50,000 are subject to MCTMT. Zone 1 (NYC five boroughs) rate is 0.60%; Zone 2 (your county) rate is 0.34%. Are you aware of this tax?"
Options: ["Yes, I know", "No, this is new to me"]
Purely educational — no routing impact. Acknowledgment flows to the brief.
NY201-8 — Prior year carryforwards.
Free-text: "Do you have any of the following from prior-year NY returns? (a) NY depreciation basis differences on assets still in service; (b) NY NOL carryforward; (c) NY credit carryforwards (investment tax credit, college tuition, etc.); (d) None of the above."
Routing: (a) → invoke Form IT-398 tracking. (b) → refuse under R-US-NOL (out of scope). (c) → flag for reviewer. (d) → continue.
NY201-9 — Retirement contributions paid by April 15, 2026.
Free-text: "If you have any retirement plan contributions for tax year 2025 that will be paid between January 1 and April 15, 2026, list them here with the plan type and amount. (Normally these flow from your federal return, but confirm.)"
Used for: cross-check against federal us-self-employed-retirement output.
NY201-10 — Estimated tax payments made for 2025.
Free-text: "For each NY estimated tax voucher you paid for 2025, enter: voucher quarter, date paid, NY state amount, NYC amount (if applicable), Yonkers amount (if applicable). For example: 'Q1, 4/15/2025, $2,000 NY, $500 NYC, $0 Yonkers.'"
Used for: Line 75 entry and balance due computation.
NY201-11 — Withholding from W-2s or 1099s.
Free-text: "If you received any W-2 forms or 1099-NECs showing NY state, NYC, or Yonkers withholding, list each one with the payer name and withholding amounts."
Used for: Lines 72, 73, 74.
NY201-12 — Prior year overpayment applied.
ask_user_input_v0:
Question: "On your 2024 NY return, did you choose to apply any overpayment to your 2025 estimated tax?"
Options: ["Yes", "No", "I received a refund", "I don't remember — I need to check my 2024 return"]
Routing: "Yes" → free-text for amount. "I don't remember" → flag for reviewer to verify.
NY201-13 — §174A R&E activity.
ask_user_input_v0 (only asked if federal return shows any Schedule C Line 17 "Legal and professional services" or Line 26 "Wages" that could be R&E-related):
Question: "Do any of your 2025 Schedule C expenses relate to research and development of your own software product or technology (not work you did for clients)? For example, contractor payments to build a prototype of your own app."
Options: ["No, all my expenses are for client deliverables", "Yes, less than $10,000 of potential R&D expenses", "Yes, more than $10,000 of potential R&D expenses", "I'm not sure"]
Routing: "No" → Position 5.15 does not fire. "Less than $10,000" → Position 5.15 fires, default NY modification path, no refusal. "More than $10,000" or "Not sure" → refuse under R-NY201-5 and route to reviewer.
NY201-14 — §168(k) bonus depreciation.
ask_user_input_v0:
Question: "In 2025, did you purchase any business equipment, computers, or other depreciable assets and claim the federal bonus depreciation (§168(k)) deduction?"
Options: ["No — I did not buy any depreciable assets", "I bought assets but used §179 expensing instead (not bonus)", "Yes — I claimed federal bonus depreciation", "I'm not sure"]
Routing: "Yes" → invoke Form IT-398 / IT-225 A-011 computation per Position 5.12. "Not sure" → flag for reviewer.
NY201-15 — Tax-exempt bond interest source.
ask_user_input_v0 (only asked if federal Form 1040 Line 2a > 0):
Question: "Your federal return shows tax-exempt interest. Where is it from?"
Options: ["All from NY state or local bonds (exempt from NY tax)", "All from non-NY state or local bonds (taxable for NY)", "Mixed — my mutual fund tax report has a breakdown", "I don't know"]
Routing: "All NY" → no Line 20 addition. "All non-NY" → full addition on Line 20. "Mixed" → ask for the fund's state-of-origin breakdown. "I don't know" → conservative default per Section 6 #5 (100% non-NY add-back).
NY201-16 — US government obligations interest.
ask_user_input_v0 (only asked if federal Form 1040 Line 2b > 0 or Form 1040 line 7 includes fund distributions):
Question: "Does any of your taxable interest or dividend income come from US government obligations (Treasury bills, Treasury money market funds, or the US government portion of a mixed bond fund)?"
Options: ["Yes, I have documentation showing the US government percentage", "Yes, but I don't have the percentage breakdown", "No"]
Routing: "Yes with documentation" → free-text for amount, enter on Line 28. "Yes without breakdown" → conservative default per Section 6 #6 (0%, no subtraction). "No" → Line 28 = $0.
NY201-17 — Pension and annuity income (age 59½+).
ask_user_input_v0 (only asked if taxpayer is 59½ or older based on date of birth):
Question: "Did you receive any pension or annuity income in 2025 (other than Social Security, government pensions, or Roth IRA distributions)?"
Options: ["No", "Yes — from a traditional IRA or private pension"]
Routing: "Yes" → free-text for amount, apply Position 5.10 exclusion up to $20,000.
NY201-18 — Empire State Child Credit eligibility.
ask_user_input_v0 (only asked if federal return has dependent children):
Question: "How many children under 17 do you have as dependents? How many of them are under 4 years old?"
Free-text responses. Used for Form IT-213 computation.
NY201-19 — Real property tax credit eligibility.
ask_user_input_v0:
Question: "Did you pay real property taxes on your primary residence in 2025, or pay rent where property taxes are included (typically for low-income renters)?"
Options: ["I own my home and paid property taxes", "I rent", "I own but my taxes are paid through escrow"]
Routing: "Own" → flag for real property tax credit consideration if income is low enough. "Rent" → real property tax credit may apply to low-income renters. Defer detailed eligibility to Form IT-214 instructions.
NY201-20 — Charitable contributions via NY Charitable Gifts Trust Fund.
ask_user_input_v0:
Question: "Did you make any contributions in 2025 to the New York State Charitable Gifts Trust Fund (the state-level charitable giving program that provides an 85% NY tax credit)?"
Options: ["No", "Yes"]
Routing: "Yes" → flag for reviewer; this is a specific NY credit that is often missed. "No" → continue.
NY201-21 — Other NY credits awareness.
ask_user_input_v0:
Question: "Do you qualify for any of these specific NY credits? (a) Long-term care insurance credit; (b) Solar or green building credits; (c) Investment in qualified emerging technology companies; (d) Volunteer firefighter/EMT credit; (e) None of these."
Options: ["(a)", "(b)", "(c)", "(d)", "(e) None"]
Routing: Any credit claim → flag for reviewer to verify eligibility and compute amount. "None" → continue.
NY201-22 — First-time NY filer or first-time NYC UBT filer flag.
ask_user_input_v0:
Question: "Is this your first time filing a NY state return, or your first time filing as a NYC resident, or your first time having NYC UBT exposure?"
Options: ["First time filing NY at all", "First year as a NYC resident", "First year with NYC UBT exposure", "None of the above — I have prior filings"]
Routing: "First time" answers → flag for reviewer as a new-filer case that may need extra attention. "None" → continue.
The base workflow provides 17 self-checks in us-tax-workflow-base Section 5. The ny-llc-filing-fee-it-204-ll skill adds Checks 18-27. This skill adds Checks 28 through 46 covering the IT-201-specific invariants.

If false: arithmetic error; halt and recompute. (Section 12)|Line 76 − Line 61|. If false: arithmetic or logic error; halt and recompute. (Section 12)This skill interacts with the following other skills in the OpenAccountants stack. Each interaction has a direction (input/output), a payload (what data flows), and an order constraint (when in the workflow).
us-tax-workflow-base v0.2+Payload: Workflow runbook, output spec, global refusals (R-US-*), 17 base self-checks, citation discipline, structured intake form scaffolding, slot 7 contract. Order: Always loaded first; this skill cannot run without it.
us-sole-prop-bookkeepingPayload: Classified Schedule C transactions and Schedule C Line 31 net profit. Order: Runs before federal SE computation; this skill consumes the Schedule C output indirectly via the federal assembly.
us-schedule-c-and-se-computationPayload: Schedule C bottom line, Schedule SE net earnings from self-employment (§1402(a) amount), deductible half of SE tax. Order: Runs before this skill. Position 5.28 and 5.29 (MCTMT) consume the NESE figure directly.
us-qbi-deductionPayload: Federal QBI deduction (Form 1040 Line 13). Order: Runs before this skill. Does NOT affect NY computation directly (NY starts from federal AGI, and QBI is below AGI at federal level). Cross-skill value: the brief notes "QBI structural non-conformity" per Section 2 of this skill.
us-self-employed-retirementPayload: Retirement deduction amount flowing to Schedule 1 Line 16. Order: Runs before this skill. This skill does not recompute.
us-self-employed-health-insurancePayload: SE health insurance deduction flowing to Schedule 1 Line 17. Order: Runs before this skill. This skill does not recompute.
us-federal-return-assemblyPayload: Federal AGI (Form 1040 Line 11), federal taxable income (Line 15), federal tax liability, final federal return status. Order: Runs immediately before this skill. Position 5.3 and Position 5.5 consume the federal AGI and lock check.
ny-llc-filing-fee-it-204-llPayload: Whether the taxpayer must file IT-204-LL (yes if SMLLC with any NY source income), the $25 fee amount, and the March 16, 2026 due date.
Order: This skill does not depend on IT-204-LL computation to produce IT-201. The two returns are independent in computation but both flow into the final deliverable. The orchestrator us-federal-ny-return-assembly coordinates them.
nyc-unincorporated-business-tax (to be built next)Payload: NYC UBT liability amount, Form NYC-202 or NYC-202S status, UBT paid during 2025 (the A-201 add-back source), and the Form IT-219 credit input. Order: This skill depends on the NYC UBT skill's output. Position 5.8 (A-201 add-back) and Position 5.24 (IT-219 credit computation) both consume the UBT amount. The orchestrator runs the NYC UBT skill before this skill's NYC-dependent positions. Interaction point: Position 5.24 receives the UBT-paid figure and applies the IT-219 sliding-scale; the resulting credit flows back to IT-201 Line 53.
ny-estimated-tax-it-2105 (to be built)Payload: 2026 quarterly estimated tax vouchers (prospective) and 2025 underpayment penalty computation (retrospective, if applicable). Order: This skill produces the inputs (2025 NY tax, 2024 NY tax for safe harbor, balance due) but does NOT compute the penalty or the 2026 vouchers. The ny-estimated-tax skill consumes this skill's output.
us-federal-ny-return-assembly (to be built)Purpose: Enforces the execution order: federal stack → ny-it-201-resident-return → nyc-unincorporated-business-tax (if applicable) → ny-llc-filing-fee-it-204-ll (if applicable) → ny-estimated-tax-it-2105 (for 2026 planning). Responsibility: Produces the final unified reviewer package with the federal return, the NY return, the NYC UBT return (if any), the IT-204-LL filing (if any), and the 2026 estimated tax schedule. Runs the cross-skill reconciliation check (A-201 add-back vs UBT paid; IT-219 credit vs UBT paid; MCTMT NESE vs Schedule C).

The horizontal arrow between retirement and SEHI indicates the circular computation handled by the federal assembly orchestrator — both skills feed each other because SEHI deduction depends on NESE, which depends on retirement contribution, which depends on SEHI deduction. The federal assembly resolves this circularity before this skill runs.

MTA MCTD maps and guidance:
Why this skill is load-bearing. The ny-it-201-resident-return skill owns four intra-NY tax layers (state + NYC + Yonkers + MCTMT) that must be coordinated correctly because they share a common tax base (NY taxable income) with layer-specific modifications. No other skill in the NY stack has the authority to compute these layers. If this skill is wrong, every downstream skill (IT-204-LL, IT-2105, orchestrator) is wrong. For this reason, the skill has aggressive self-checks (28-46) and demands upstream lock before proceeding.
Why the §174/§174A classification issue is handled with a refusal rather than a default. NY Notice N-26-1 resolves the conformity question for 2025: NY decouples and individuals use Form IT-225 A-225/S-221/S-222. The remaining risk is factual classification. For software developers, distinguishing ordinary §162 client deliverable work from §174/§174A R&E can be material and fact-sensitive, so this skill refuses material classification issues rather than silently creating or omitting a large NY modification.
Why the MCTMT per-individual-per-zone rule gets its own position. The rule in NY Tax Law §801 is simple in text but easy to misapply in practice. A joint return with one spouse above the $50,000 threshold and one below looks, at first glance, like it should aggregate the spouses' bases for a single threshold test. It does not. Each spouse is tested separately. This is a common error in self-prepared returns and even in some professional returns. The dedicated positions (5.28-5.30) with explicit worked examples (Example 3, Carlos + Maria) anchor the rule in practice.
Why the NYC UBT credit computation is done in this skill rather than the NYC UBT skill. The NYC UBT skill computes the UBT liability on Form NYC-202/NYC-202S. The sliding-scale credit under IT-219 is a NY state credit that happens to reference the NYC UBT paid amount — it is structurally a state-level credit, not a NYC-level credit. Form IT-219 is an NYSDTF form, not an NYC Department of Finance form. For this reason, the IT-219 computation belongs in the state skill (this skill), with a cross-skill dependency on the NYC skill for the UBT-paid amount. The data flow is clear: NYC UBT skill produces UBT paid; this skill produces IT-219 credit and flows it to IT-201 Line 53.
Why Albany, Buffalo, Rochester are explicitly called out as non-MCTD. Self-preparing freelancers in upstate NY sometimes mistakenly believe MCTMT applies to them because they have NYC clients or because "NY = NYC" in the mental model. The MCTD is explicitly defined in NY Tax Law §800(b) as 12 counties (NYC five boroughs + 7 surrounding counties). Albany, Buffalo, Rochester, Syracuse, Binghamton, and the entire North Country are NOT in the MCTD. Example 5 (Rachel) exists specifically to anchor this distinction for both the skill and the reviewer. The brief explicitly states "MCTMT = $0 because Albany County is not in the MCTD" when applicable, so there is no ambiguity about whether MCTMT was missed or intentionally zero.
Why the recapture worksheet is explained as a method, not a separate tax. The $107,650 threshold and the bands above it produce what journalists call the "recapture tax" or "supplemental tax on high earners." In the actual statute (§601(d)(1) and the parallel sections), this is not a separate tax — it is a different method of computing the same tax base that phases out the bracket benefit. The skill explains this explicitly in Position 5.19 to prevent a reviewer from treating it as an additional tax to be computed alongside the regular tax. Treating it as a separate tax would double-count.
Why the brief includes a sanity check on effective rate (Example 6, Jake). For high-income taxpayers, a 10-11% combined effective rate (state + NYC + MCTMT) on NYAGI is reasonable. A computed effective rate below 8% or above 12% is a signal of either a math error or a missed position. The brief includes the effective rate as a reasonableness flag.
Why the skill does not compute NY credits for taxes paid to another state (R-NY201-6). The §620 credit is often materially valuable (potentially thousands of dollars for a freelancer with significant out-of-state income) but it requires computing the credit cap under the §620(e) limitation formula, which in turn requires detailed NY source vs non-NY source allocation. This allocation requires Form IT-203-A or equivalent analysis and is too complex to handle reliably in a skill that is primarily designed for single-state resident cases. The refusal preserves taxpayer rights by flagging the credit for reviewer rather than silently omitting it.
Why the §615(f) itemized limitation is refused rather than computed. The limitation phases out itemized deductions through multiple income bands under 20 NYCRR §112.3, with different formulas at different NYAGI levels. The computation is rarely worth it for freelance developers (who typically benefit from the standard deduction anyway), and the refusal preserves correctness in the rare case where it matters.

Recapture worksheet mechanism explanation
The recapture worksheet used for NYAGI > $107,650 eliminates the benefit of the lower brackets in a graduated phase-out, producing an almost-flat tax at the top marginal rate for high earners. This is the mechanism journalists call the "NY recapture tax" or the "supplemental tax on high earners." It is not an additional tax; it is a reconstruction of the same tax using a different computation method that denies the bracket benefit. The skill computes this correctly via the worksheet and does NOT treat it as a separate tax.Form IT-201-I (2025), "Tax computation — NYAGI of more than $107,650"

MCTMT $50,000 threshold applied per individual and per zone for joint returns
The $50,000 threshold is applied per individual and per zone. On a joint return where both spouses have self-employment income allocated to the MCTD, each spouse's per-zone NESE is tested separately against the $50,000 threshold. If either spouse's individual per-zone NESE is $50,000 or less, that spouse's base is excluded from the combined joint return MCTMT computation for that zone.

Residency gate trigger
The intake has identified the taxpayer as a potential NY filer.NY Tax Law §605(b); 20 NYCRR §105.20; Form IT-201-I (2025), "New York State full-year residents: Who must file?"
Residency gate rule
Confirm the taxpayer was a New York State full-year resident for all of 2025. Under NY Tax Law §605(b), a taxpayer is a NY resident if EITHER (a) they are domiciled in NY for the entire year, OR (b) they are not domiciled in NY but maintain a permanent place of abode in NY and spend more than 183 days of the year in NY. Apply the domicile test first (where the taxpayer intends to return, where their permanent home is, where their family and belongings are); apply the statutory residency test only if domicile is elsewhere. Full-year means the entire calendar year — any move into or out of NY during 2025 disqualifies the taxpayer from IT-201 and routes them to IT-203 (out of scope, R-NY201-1 fires).NY Tax Law §605(b); 20 NYCRR §105.20; Form IT-201-I (2025), "New York State full-year residents: Who must file?"
Residency gate conservative default
If residency is ambiguous at any point in the year (e.g., the taxpayer claims domicile in NY but spent substantial time outside NY, or the taxpayer moved to NY "sometime in early 2025"), refuse under R-NY201-1 and route to the not-yet-built part-year resident skill. Do not attempt to split the year.NY Tax Law §605(b); 20 NYCRR §105.20
Filing status trigger
Residency gate (5.1) cleared.Form IT-201-I (2025), Step 2, Item A.
Filing status rule
The filing status on Form IT-201 must match the filing status on the federal Form 1040. The only exceptions are the five specific situations listed in Form IT-201-I Item A: (a) one spouse is a NY resident and the other is not; (b) one spouse's whereabouts is unknown with reasonable efforts made to locate; (c) spouse refuses to sign a joint NY return with objective evidence of alienation; (d) other narrow cases. For a full-year NY resident freelancer, none of the exceptions typically applies, and the NY filing status simply mirrors the federal choice: Single, MFJ, MFS, HoH, or QSS.Form IT-201-I (2025), Step 2, Item A.
Filing status conservative default
Default to the federal filing status. If the federal return's filing status is ambiguous, refuse under R-US-CONTENT-MISMATCH pending reviewer clarification — never guess between single and MFS.Form IT-201-I (2025), Step 2, Item A.
Federal AGI import trigger
Filing status confirmed.NY Tax Law §611; Form IT-201-I (2025), Step 3.
Federal AGI import rule
NY starts from federal adjusted gross income (Form 1040 line 11) as the computation base. Import the federal AGI from the upstream federal return without modification. The upstream federal stack (us-sole-prop-bookkeeping → us-schedule-c-and-se-computation → us-self-employed-retirement → us-self-employed-health-insurance → us-federal-return-assembly) must have produced a locked federal AGI before this skill runs. Any attempt to recompute federal AGI in this skill is an error — the federal return is the source of truth. The individual income components (wages, interest, dividends, business income, capital gains, IRA distributions, pension income, Social Security, etc.) flow to Form IT-201 lines 1 through 19 individually. Line 19 is the "federal AGI from your federal return" reconciliation check.NY Tax Law §611 (NY taxable income starts from federal taxable income, but the mechanics via §612 effectively make the starting point federal AGI); Form IT-201-I (2025), Step 3.
Federal AGI import conservative default
If the federal return is not locked, refuse to proceed. The orchestrator `us-federal-ny-return-assembly` enforces the federal-before-state execution order.NY Tax Law §611; Form IT-201-I (2025), Step 3.
Layer determination trigger
Federal AGI imported.NY Tax Law §605(b); NYC Admin Code §11-1701(c); Form IT-201-I (2025), Items D2, E, F; Yonkers City Code §92-5.
Layer determination rule
Determine which intra-NY tax layers apply, in this order: 1. NYC resident? Check if the taxpayer was domiciled in NYC (Manhattan, Bronx, Brooklyn, Queens, Staten Island) for the full year, OR was a statutory NYC resident (permanent place of abode in NYC + 184+ days in NYC). If yes, NYC resident tax layer applies (lines 47a-53). 2. Yonkers resident? Check if the taxpayer maintained living quarters in Yonkers during any part of 2025 (Item D2 on Form IT-201). If yes and the facts support Yonkers residency, Yonkers resident surcharge applies (line 55). 3. Yonkers nonresident earnings? Check if the taxpayer is NOT a Yonkers resident but earned wages or self-employment income from Yonkers sources. If yes, Yonkers nonresident earnings tax applies (line 56). 4. MCTMT applicability? Check if the taxpayer has net earnings from self-employment allocated to either MCTD Zone 1 or Zone 2 exceeding $50,000. If yes, MCTMT applies (lines 54a, 54b). Note: A freelancer based in Manhattan is in Zone 1, a freelancer based in Yonkers or Westchester is in Zone 2, a freelancer based in Albany or Buffalo is in neither zone. A taxpayer can be subject to multiple layers simultaneously: e.g., a Manhattan freelancer is subject to NY state tax + NYC resident tax + MCTMT Zone 1. A Yonkers freelancer is subject to NY state tax + Yonkers resident surcharge + MCTMT Zone 2.NY Tax Law §605(b); NYC Admin Code §11-1701(c); Form IT-201-I (2025), Items D2, E, F; Yonkers City Code §92-5.
Layer determination conservative default
If NYC residency is ambiguous (e.g., the taxpayer has a Manhattan apartment but spent substantial time elsewhere), ask for confirmation via `ask_user_input_v0` with the four options: "Full-year NYC resident" / "Part-year NYC resident" / "Not a NYC resident, but had NYC living quarters" / "No NYC connection at all." If the answer is "Part-year NYC resident," the taxpayer's broader NY residency must also be reconsidered — route to reviewer.NY Tax Law §605(b); NYC Admin Code §11-1701(c)
Upstream integration trigger
Residency within NY determined.`us-tax-workflow-base v0.2` Section 9 (interaction model); workflow execution order.
Upstream integration rule
Confirm that all upstream federal skill outputs are present and internally consistent: `us-sole-prop-bookkeeping`: Schedule C Part II totals; `us-schedule-c-and-se-computation`: Schedule C net profit (Line 31), SE tax, half of SE tax; `us-self-employed-retirement`: retirement deduction (Schedule 1 Line 16); `us-self-employed-health-insurance`: SE health insurance deduction (Schedule 1 Line 17); `us-qbi-deduction`: QBI deduction amount (Form 1040 Line 13); `us-federal-return-assembly`: final federal AGI (Form 1040 Line 11) and federal taxable income (Line 15). Record each upstream value in the reviewer brief's "Federal inputs" section for traceability. If any upstream value is missing, refuse to proceed and identify the missing skill by name.`us-tax-workflow-base v0.2` Section 9 (interaction model); workflow execution order.
Upstream integration conservative default
Never recompute federal figures. Always use the upstream skill's output as authoritative.`us-tax-workflow-base v0.2` Section 9 (interaction model); workflow execution order.
Line 20 additions trigger
Federal AGI imported and includes tax-exempt interest from state and local bonds of other states.NY Tax Law §612(b)(1); Form IT-201-I (2025), Line 20.
Line 20 additions rule
Under NY Tax Law §612(b)(1), NY taxes interest income from state and local bonds of other states (not NY or its local governments, which remain tax-exempt). If the taxpayer's federal return shows tax-exempt interest on Form 1040 Line 2a, determine the portion attributable to non-NY state or local bonds and enter that portion on IT-201 Line 20. If the 1099-INT or mutual fund statement does not break down interest by state of origin, ask the taxpayer or the fund's tax reporting package (most large mutual fund families publish per-state allocation schedules each January).NY Tax Law §612(b)(1); Form IT-201-I (2025), Line 20.
Line 20 additions conservative default
If the state-of-origin breakdown is not available, assume 100% of the tax-exempt interest is from non-NY sources and add it back. This is conservative because it maximizes NY taxable income. Flag the assumption in the reviewer brief.NY Tax Law §612(b)(1); Form IT-201-I (2025), Line 20.
Line 22 additions trigger
Federal AGI includes a distribution from a NY 529 plan that was used for non-qualified expenses, OR the taxpayer deducted NY 529 contributions in prior years and is now recapturing them.Form IT-201-I (2025), Line 22.
Line 22 additions rule
Rarely relevant for freelance developers unless they have a child with a 529 plan. If relevant, follow Form IT-201-I Line 22 instructions and enter the recapture amount. Defer detailed computation to the 529 plan administrator's tax statement.Form IT-201-I (2025), Line 22.
Line 22 additions conservative default
Assume no 529 recapture applies unless the taxpayer affirmatively reports one.Form IT-201-I (2025), Line 22.
Line 23 additions trigger
Any of the IT-225 addition modification codes apply. The most common for freelance developers is A-201 (personal income taxes and unincorporated business taxes deducted in determining federal income).NY Tax Law §612(b)(3); Form IT-225-I (2025), A-201 code; Form IT-201-I (2025), Line 23.
Line 23 additions rule
Compute each applicable IT-225 addition and enter the total on Form IT-201 Line 23, with Form IT-225 attached. For a NYC-resident freelance developer who paid NYC UBT, the A-201 add-back is critical: the UBT paid during 2025 was deducted on federal Schedule C (most commonly on Line 23 "Taxes and licenses" or Line 17 "Legal and professional fees"), but NY does not allow a state-level deduction for unincorporated business taxes. The full amount of UBT deducted federally must be added back on IT-225 code A-201. Other A-codes to check for freelance developers: A-009: Federal bonus depreciation (§168(k)). If the freelancer placed any business asset in service during 2025 and claimed federal bonus depreciation, add back the difference between the federal deduction and the NY depreciation computed on Form IT-398. This applies to equipment, computers, software, vehicles, and any other depreciable business asset. The A-009 add-back is replaced in 2025 and later by the IT-225 A-011 code — use A-009 only if the taxpayer has pre-2025 bonus depreciation carryovers. A-113: Interest income on state and local bonds of other states (see Position 5.6 — this is the entry point if reported via IT-225 rather than directly on Line 20). A-301: NYC flexible benefits program (IRC §125) — rare for self-employed.NY Tax Law §612(b)(3); Form IT-225-I (2025), A-201 code; Form IT-201-I (2025), Line 23.
Line 23 additions conservative default
If the taxpayer paid UBT in 2025 and the amount is not clearly documented, refuse to proceed and require the taxpayer to produce the NYC-202 or NYC-202S from the companion `nyc-unincorporated-business-tax` skill. Never estimate UBT for the A-201 add-back — it must match the actual amount deducted on federal Schedule C.NY Tax Law §612(b)(3); Form IT-225-I (2025), A-201 code; Form IT-201-I (2025), Line 23.
Line 28 subtractions trigger
Federal AGI includes interest income on US government bonds, Treasury bills, or other US Treasury obligations.NY Tax Law §612(c)(1); Form IT-201-I (2025), Line 28.
Line 28 subtractions rule
Under NY Tax Law §612(c)(1), interest income from US government obligations is exempt from NY state tax. Subtract the amount on IT-201 Line 28. Typical sources: Treasury bills held directly, Treasury money market funds, and the US government portion of mixed bond funds. Most mutual fund families publish the percentage of dividends attributable to US government obligations each January.NY Tax Law §612(c)(1); Form IT-201-I (2025), Line 28.
Line 28 subtractions conservative default
If the mutual fund does not report the US government percentage, assume 0% and do not claim the subtraction. This is conservative (higher NY tax).NY Tax Law §612(c)(1); Form IT-201-I (2025), Line 28.
Line 29 subtractions trigger
The taxpayer is age 59½ or older and received pension or annuity income included in federal AGI.NY Tax Law §612(c)(3-a); Form IT-201-I (2025), Line 29.
Line 29 subtractions rule
Up to $20,000 per individual of qualifying pension and annuity income is excluded from NY taxable income under §612(c)(3-a). "Qualifying" means private pensions, traditional IRA distributions, and certain other retirement income — but NOT Roth IRA distributions (because those are already federally exempt), and NOT federal, state, or local government pensions (which have their own full exclusion on Line 26). The $20,000 cap is per individual on a joint return, so a couple can exclude up to $40,000 combined if each spouse has qualifying income.NY Tax Law §612(c)(3-a); Form IT-201-I (2025), Line 29.
Line 29 subtractions conservative default
Rarely applies to active freelance developers but must be checked for older taxpayers. If the taxpayer turned 59½ during 2025, include only the portion received after the age-59½ date (Form IT-201-I Line 29 provides the proration).NY Tax Law §612(c)(3-a); Form IT-201-I (2025), Line 29.
Line 31 subtractions trigger
Any of the IT-225 subtraction modification codes apply.NY Tax Law §612(c); Form IT-225-I (2025); Form IT-201-I (2025), Line 31.
Line 31 subtractions rule
Compute each applicable IT-225 subtraction and enter the total on Form IT-201 Line 31, with Form IT-225 attached. The most common for freelance developers: S-125: NY depreciation subtraction for bonus depreciation assets — this is the annual flip side of the A-009 / IT-225 A-011 add-back. If the taxpayer added back bonus depreciation in a prior year, they receive a NY depreciation deduction each subsequent year on the normalized MACRS schedule until the asset is fully recovered. Use Form IT-398 to track the running balance. S-118: Certain income from services performed as a self-employed individual subject to NYC UBT — rarely material but exists to prevent double-counting.NY Tax Law §612(c); Form IT-225-I (2025); Form IT-201-I (2025), Line 31.
Line 31 subtractions conservative default
Apply only modifications the taxpayer can affirmatively document. Never estimate.NY Tax Law §612(c); Form IT-225-I (2025); Form IT-201-I (2025), Line 31.
IT-225 OBBBA decoupling trigger
The taxpayer has a federal item subject to New York 2025 OBBBA decoupling. For freelancers, the main triggers are qualified production property under IRC §168(n), foreign or domestic R&E expenditures under IRC §§174 and 174A, and any documented federal/state depreciation difference that requires a NY modification. Use Form IT-225 and NY Notice N-26-1 guidance.NY Notice N-26-1; Form IT-225-I (2025)
IT-225 OBBBA decoupling rule
For 2025 NY individual returns, report OBBBA decoupling modifications on Form IT-225. Qualified production property uses A-209/S-213 with Form IT-398 support. R&E expenditures use A-225 with S-221 for expenditures paid or incurred on or after January 1, 2025, or S-222 for pre-2025 expenditures.NY Notice N-26-1; Form IT-225-I (2025)
IT-225 OBBBA decoupling default
Apply only documented NY modifications. If the federal deduction, NY amortization amount, or classification is unclear, refuse and route to reviewer rather than guessing the IT-225 amount.NY Notice N-26-1; Form IT-225-I (2025)
Line 32/33 trigger
All NY additions (Lines 20-24) and subtractions (Lines 25-31) computed.Form IT-201 (2025) Lines 19-33; Form IT-201-I (2025), Step 4.
Line 32/33 rule
Compute Form IT-201 Line 32 (sum of Lines 19 + 23 + 24 − [28 + 29 + 30 + 31]) as the recomputed federal AGI with NY modifications. This equals NYAGI. Enter on Line 33. This is the single most important figure downstream — it drives the deduction limit, the tax table vs rate schedule vs worksheet decision, and many credit phase-outs.Form IT-201 (2025) Lines 19-33; Form IT-201-I (2025), Step 4.
Line 32/33 conservative default
Double-check the arithmetic. A wrong NYAGI cascades into every downstream line.Form IT-201 (2025) Lines 19-33; Form IT-201-I (2025), Step 4.
Standard vs itemized trigger
NYAGI computed.NY Tax Law §614 (standard), §615 (itemized); §615(f) (limitation); Form IT-201-I (2025), Step 5, Line 34.
Standard vs itemized rule
Compute both the NY standard deduction (from the Section 3 figures table by filing status) and the NY itemized deduction (via Form IT-196). Use whichever is larger. For most freelance developers without a mortgage, significant charitable contributions, or state tax deductions exceeding the standard deduction, the standard deduction is the right choice. Critical NYAGI > $100,000 note: If NYAGI exceeds $100,000, the NY itemized deduction is subject to a phase-out limitation under §615(f). The limitation is complex and out of scope for this skill. If the taxpayer's NYAGI exceeds $100,000 AND the taxpayer would benefit from itemizing (e.g., large mortgage interest, large state tax deduction, large charitable contribution), refuse under R-NY201-3 and route to reviewer. The simple case (NYAGI > $100,000 but standard deduction is obviously better) proceeds normally.NY Tax Law §614 (standard), §615 (itemized); §615(f) (limitation); Form IT-201-I (2025), Step 5, Line 34.
Standard vs itemized conservative default
When in doubt, take the standard deduction. It is simpler, it does not require Form IT-196, and for most freelance developers it produces nearly the same result.NY Tax Law §614 (standard), §615 (itemized); §615(f) (limitation); Form IT-201-I (2025), Step 5, Line 34.
§174/§174A trigger
The taxpayer has foreign or domestic research and experimental expenditures for 2025, including domestic R&E deducted federally under OBBBA §174A. For software developers, this is usually speculative own-product development, not ordinary client deliverable work.NY Notice N-26-1; Form IT-225-I (2025)
Enacted NY R&E decoupling rule
NY Notice N-26-1 confirms New York decouples from the federal treatment of foreign and domestic R&E expenditures for tax years beginning on or after January 1, 2025. Individuals report the modifications on Form IT-225 using A-225 plus S-221 or S-222. Post-2024 expenditures are amortized over 60 months for NYS purposes.NY Notice N-26-1; Form IT-225-I (2025)
R&E Form IT-225 modification rule
If the federal return deducted domestic R&E immediately under §174A, add back the federal deduction using Form IT-225 code A-225 and subtract the allowable NY 60-month amortization amount using S-221. Track the remaining NY recovery for later years.NY Notice N-26-1; Form IT-225-I (2025)
Required NY modification after NY Notice N-26-1
Do not omit the NY modification merely because the federal return deducted domestic R&E immediately under §174A. NY Notice N-26-1 requires the 2025 NY modification on Form IT-225 when the item is within §174/§174A.NY Notice N-26-1; Form IT-225-I (2025)
§174/§174A default

Dependent exemption rule
Multiply the number of dependents by $1,000 and enter on Line 36. This is a straight deduction from NY taxable income, not a credit. Note that the dependents must be the same as on the federal return (or dependents the taxpayer was entitled to claim federally but chose not to, per Item H on Form IT-201).NY Tax Law §616; Form IT-201-I (2025), Step 5, Line 36.

Method selection trigger
NY taxable income computed.Form IT-201-I (2025), "How to calculate your 2025 New York State tax"; NY Tax Law §601.
Method selection rule
Determine which of three methods to use, per the decision matrix in Section 3: NYAGI ≤ $107,650 AND taxable income < $65,000: Use the NY State Tax Table (lookup); NYAGI ≤ $107,650 AND taxable income ≥ $65,000: Use the NY State Tax Rate Schedule; NYAGI > $107,650: Use the Tax Computation Worksheet (the recapture mechanism). The recapture worksheet eliminates the benefit of the lower brackets for high earners. It is NOT an additional tax; it is a reconstruction of the same tax base using a different method that produces an almost-flat tax at the taxpayer's top marginal rate. This is the mechanism journalists call the "NY recapture" or the "supplemental tax on high earners."Form IT-201-I (2025), "How to calculate your 2025 New York State tax"; NY Tax Law §601.
Method selection conservative default
Always use the method dictated by the NYAGI level. Never use the tax table for NYAGI > $107,650 — this is specifically prohibited by Form IT-201-I and produces a wrong result.Form IT-201-I (2025), "How to calculate your 2025 New York State tax"; NY Tax Law §601.
State tax computation trigger
Computation method selected.NY Tax Law §601; Form IT-201-I (2025), pages 32-40.
State tax computation rule
If using the tax table: Look up the tax in the NY State Tax Table using NY taxable income (Line 38) and filing status column. Enter on Line 39. If using the rate schedule: Apply the bracket structure from Section 3 to compute the tax, and enter on Line 39. The formula is: Tax = (applicable marginal rate × amount over bracket floor) + cumulative tax at bracket floor. For example, a single filer with NY taxable income of $95,000 falls in the $80,650-$215,400 bracket (6.00%): Tax = 6.00% × ($95,000 − $80,650) + tax at $80,650 = 6.00% × $14,350 + $4,579 = $861 + $4,579 = $5,440 → rounded to $5,440. The "tax at $80,650" is the cumulative tax from all lower brackets applied in sequence. If using the tax computation worksheet: Follow the worksheet in Form IT-201-I page 34 exactly. The worksheet has different versions for taxpayers with NYAGI in different bands ($107,650 to $157,650, $157,650 to $211,550, $211,550 to $1,077,550, $1,077,550 to $5,000,000, $5,000,000 to $25,000,000, and over $25,000,000 for single filers; different bands for other filing statuses). Each band recomputes the tax to phase out the bracket benefit. For any taxpayer with NYAGI > $107,650, flag as a reviewer attention item and show the full worksheet computation in the brief. The worksheet is mechanical but error-prone.NY Tax Law §601; Form IT-201-I (2025), pages 32-40.

If the taxpayer's filing status or NYAGI is ambiguous at the method-selection boundary, use the method that produces the higher tax. Never use the wrong method to get a lower number.NY Tax Law §601; Form IT-201-I (2025), pages 32-40.
Household credit trigger
NY state tax computed.NY Tax Law §606(b); Form IT-201-I (2025), Line 40; tables 1, 2, 3.
Household credit rule
The NY household credit is a small credit (typically $75 or less) based on NYAGI and filing status. It does NOT apply if the taxpayer can be claimed as a dependent on another return (Item C = Yes on the form) — in that case, skip the credit. Otherwise, use Table 1, 2, or 3 from Form IT-201-I based on filing status.NY Tax Law §606(b); Form IT-201-I (2025), Line 40; tables 1, 2, 3.

Other credits trigger
Taxpayer qualifies for other NY credits (resident credit for taxes paid to another state, nonrefundable credits from Form IT-201-ATT).NY Tax Law §620 (resident credit); Form IT-201-ATT (2025); Form IT-201-I (2025), Line 41.
Other credits rule
Most freelance developers will not have a resident credit (§620) because their income is not sourced to another state. The NY nonrefundable credit line (Line 41) collects various credits from Form IT-201-ATT Section A. Defer detailed computation to the specific credit forms. For this skill's scope, most freelancers will have $0 on Line 41.NY Tax Law §620 (resident credit); Form IT-201-ATT (2025); Form IT-201-I (2025), Line 41.

NYC resident tax trigger
Taxpayer was a full-year NYC resident (Position 5.4 determined this).NYC Admin Code §11-1701; Form IT-201-I (2025), Line 47a, "How to calculate your 2025 New York City tax."
NYC resident tax rule
Compute NYC taxable income — which equals NY taxable income (Line 38) for most full-year NYC residents with no NYC-specific adjustments. Then apply the NYC tax table (if NYC taxable income < $65,000) or the NYC rate schedule (from Section 3, if ≥ $65,000). The NYC rate schedule uses four brackets with rates 3.078%, 3.762%, 3.819%, 3.876%. Bracket thresholds vary by filing status (see Section 3 tables). Example for a NYC resident single filer with NY taxable income of $95,000: NYC taxable income = $95,000; NYC is in the top bracket (> $50,000 for single); NYC tax = 3.078% × $12,000 + 3.762% × ($25,000 − $12,000) + 3.819% × ($50,000 − $25,000) + 3.876% × ($95,000 − $50,000) = $369.36 + $489.06 + $954.75 + $1,744.20 = $3,557.37 → rounded to $3,557.

NYC UBT credit trigger
Taxpayer is a NYC resident who paid NYC Unincorporated Business Tax for 2025 (typically because they are a freelance developer with NYC gross business income > $95,000).NYC Admin Code §11-503(b); NY Tax Law §606(bb); Form IT-219 and instructions; Form IT-201-ATT (2025) Section C; Form IT-201-I (2025), Line 53.
NYC UBT credit rule
The NYC UBT credit under NYC Admin Code §11-503(b) flows as follows: 1. The UBT amount paid (from the companion `nyc-unincorporated-business-tax` skill's output) is carried to Form IT-219 (NYC UBT credit computation). 2. Form IT-219 applies the sliding-scale credit based on NYC taxable income: NYC taxable income ≤ $42,000: 100% of UBT paid is credited; $42,001 to $141,999: sliding from 100% down to 23% (linear phase-out); ≥ $142,000: 23% of UBT paid is credited. 3. The resulting credit flows to Form IT-201-ATT Section C (Line 10 on IT-201-ATT). 4. From IT-201-ATT Section C, the total flows to Form IT-201 Line 53. This is the skill's most important cross-skill interaction. The UBT amount must come from the `nyc-unincorporated-business-tax` skill, which in turn requires the full NYC-202 or NYC-202S computation. This skill does NOT compute UBT itself — it only applies the IT-219 sliding scale and flows the credit to IT-201. The sliding-scale phase-out is a linear interpolation between the $42,000 (100%) and $142,000 (23%) anchor points. Form IT-219 provides the exact computation worksheet. For a NYC resident freelance developer in the middle of the phase-out range, the effective credit rate can be calculated as: Credit rate = 1.00 − ((NYC taxable income − $42,000) / ($142,000 − $42,000)) × (1.00 − 0.23) = 1.00 − ((NYC taxable income − $42,000) / $100,000) × 0.77. For example, a NYC resident single freelance developer with NYC taxable income of $95,000 who paid $2,500 of UBT: Credit rate = 1.00 − ((95,000 − 42,000) / 100,000) × 0.77 = 1.00 − (53,000 / 100,000) × 0.77 = 1.00 − 0.408 = 0.592 → 59.2%. Credit = $2,500 × 0.592 = $1,480 → rounded to $1,480. Enter the credit on Form IT-219, carry to IT-201-ATT Section C, and then to IT-201 Line 53.NYC Admin Code §11-503(b); NY Tax Law §606(bb); Form IT-219 and instructions; Form IT-201-ATT (2025) Section C; Form IT-201-I (2025), Line 53.

NYC school tax credit trigger
Taxpayer was a NYC resident for any part of the year.NYC Admin Code §11-1706; Form IT-201-I (2025), Lines 69 and 69a.
NYC school tax credit rule
The NYC school tax credit has two components: Fixed amount (Line 69): $63 for single filers, $125 for MFJ/QSS/HoH — refundable for all NYC residents regardless of income. Rate reduction (Line 69a): Small additional credit for NYC residents with income under $500,000. Enter the fixed amount on Line 69 unconditionally for NYC residents. Enter the rate reduction on Line 69a if income is under $500,000.NYC Admin Code §11-1706; Form IT-201-I (2025), Lines 69 and 69a.

Taxpayer was a Yonkers full-year resident (determined in Position 5.4).Yonkers City Code §92-5; NY Tax Law Article 30-A; Form IT-201-I (2025), Line 55.
Yonkers resident surcharge rule
The Yonkers resident income tax surcharge is 16.75% of NY state tax (Line 50). Compute: Yonkers resident surcharge = 16.75% × Line 50. Enter on Line 55. If filing jointly and only one spouse was a Yonkers resident, the surcharge is computed as if separate federal returns had been filed — flag this case as R-NY201-8 (split-residence couples) and route to reviewer.Yonkers City Code §92-5; NY Tax Law Article 30-A; Form IT-201-I (2025), Line 55.

Apply the 16.75% rate uniformly. Do not reduce the rate.Yonkers City Code §92-5; NY Tax Law Article 30-A; Form IT-201-I (2025), Line 55.
Yonkers nonresident earnings trigger
Taxpayer is NOT a Yonkers resident but earned wages or self-employment income from Yonkers sources. This applies if the taxpayer has a Yonkers employer (W-2 wages sourced to Yonkers) or performed self-employment work in Yonkers.Yonkers City Code §92-141; NY Tax Law Article 30-B; Form Y-203; Form IT-201-I (2025), Line 56.
Yonkers nonresident earnings rule
The Yonkers nonresident earnings tax is 0.50% of Yonkers-source wages and self-employment earnings minus a $3,000 exemption. Compute using Form Y-203 (the Yonkers nonresident earnings tax form), and enter the resulting amount on Line 56.Yonkers City Code §92-141; NY Tax Law Article 30-B; Form Y-203; Form IT-201-I (2025), Line 56.

MCTMT Zone 1 trigger
Taxpayer has net earnings from self-employment allocated to MCTD Zone 1 (NYC five boroughs) that exceed $50,000.NY Tax Law §800-§805; Form IT-201-I (2025), Line 54a.
MCTMT Zone 1 rule
MCTMT Zone 1 tax = 0.60% × Zone 1 NESE if Zone 1 NESE > $50,000. If Zone 1 NESE ≤ $50,000, MCTMT Zone 1 is $0. Critical per-individual-per-zone rule. The $50,000 threshold applies separately to each individual and each zone. On a joint return where both spouses have self-employment income in Zone 1: Each spouse's Zone 1 NESE is tested separately against $50,000; If spouse A has $75,000 Zone 1 NESE and spouse B has $40,000 Zone 1 NESE, only spouse A's $75,000 is included in the joint Line 54a computation (spouse B's $40,000 is below the threshold and excluded); The included amounts are summed for the joint return. For a full-year NYC resident freelance software developer: Zone 1 NESE typically equals 100% of Schedule C net earnings from self-employment (the §1402(a) amount, which is 92.35% of Schedule C net profit). This is because the developer's place of business is in Zone 1 (home office in Manhattan, Brooklyn, etc.) and all business activity is attributed to that zone. Computation for a single NYC resident freelancer with Schedule C net profit of $180,000: NESE (§1402(a)) = $180,000 × 0.9235 = $166,230; Zone 1 NESE allocation = $166,230 (all from NYC); Threshold check: $166,230 > $50,000 → MCTMT applies; Zone 1 MCTMT = 0.60% × $166,230 = $997.38 → rounded to $997. Enter on Line 54a. Note: NESE is derived from §1402(a), not Schedule C line 31 directly. The 92.35% adjustment (1 − 7.65% employer-equivalent SE tax) is built into the §1402(a) definition. This skill pulls the NESE figure from the `us-schedule-c-and-se-computation` skill's output; it does not recompute.NY Tax Law §800-§805; Form IT-201-I (2025), Line 54a.
MCTMT Zone 1 conservative default
If the allocation between Zone 1 and Zone 2 is ambiguous (e.g., the taxpayer works both in Manhattan and in Westchester), use the taxpayer's primary place of business. If the taxpayer genuinely splits activity between zones, the allocation requires Form IT-203-A — refuse under R-NY201-7.NY Tax Law §800-§805; Form IT-201-I (2025), Line 54a.
MCTMT Zone 2 trigger
Taxpayer has NESE allocated to MCTD Zone 2 (Rockland, Nassau, Suffolk, Orange, Putnam, Dutchess, Westchester) that exceeds $50,000.NY Tax Law §800-§805; Form IT-201-I (2025), Line 54b.
MCTMT Zone 2 rule
MCTMT Zone 2 tax = 0.34% × Zone 2 NESE if Zone 2 NESE > $50,000. Same per-individual-per-zone rule as Position 5.28. For a full-year Westchester or Nassau resident freelance developer: Zone 2 NESE typically equals 100% of Schedule C net earnings. The rate is 0.34% (half the Zone 1 rate, reflecting the less intensive use of MTA infrastructure by non-NYC residents). Computation for a single Westchester freelancer with Schedule C net profit of $180,000: NESE = $180,000 × 0.9235 = $166,230; Zone 2 NESE allocation = $166,230 (all from Westchester); Threshold check: $166,230 > $50,000 → MCTMT applies; Zone 2 MCTMT = 0.34% × $166,230 = $565.18 → rounded to $565.

Refundable credits trigger
Taxpayer qualifies for refundable NY credits. The most common for freelance developers with children: Empire State Child Credit (Line 63, via Form IT-213): Up to $1,000 per child under 4, up to $330 per child age 4-16. Income phase-outs apply. NY Earned Income Credit (Line 65, via Form IT-215): NY EIC is 30% of the federal EIC for full-year residents. For a freelance developer with significant Schedule C net earnings, the EIC is usually phased out. NYC EIC (Line 70): Similar mechanics for NYC residents. Real property tax credit (Line 67, via Form IT-214): For homeowners and renters with low income. College tuition credit (Line 68): For families with higher education expenses.NY Tax Law §606 (various subsections); Form IT-201-I (2025), Lines 63-70; specific credit forms.

Line 76 = total payments. If Line 76 > Line 61, the difference is overpaid (Line 77). If Line 76 < Line 61, the difference is owed (Line 78). Critical reviewer flag: If Line 78 (amount owed) is significant (> $1,000), the taxpayer may owe an underpayment penalty. Form IT-2105.9 computes this penalty.

R-NY201-1 — Part-year or nonresident taxpayer
This skill prepares only full-year New York State resident returns on Form IT-201. Part-year residents and nonresidents must file Form IT-203, Nonresident and Part-Year Resident Income Tax Return, which applies different income allocation rules under NY Tax Law §631. Form IT-203 is outside this skill's scope. Please consult an Enrolled Agent or CPA familiar with NY part-year and nonresident returns.NY Tax Law §631
R-NY201-2 — Convenience-of-the-employer remote worker case
New York's convenience-of-the-employer rule (20 NYCRR §132.18(a)) treats wages as New York source when a nonresident performs services outside New York for their convenience rather than the employer's necessity. This rule creates complex sourcing questions that require careful analysis of the bona fide employer office test and the employer's policies. This skill does not handle convenience-of-the-employer determinations. Please consult a CPA familiar with NY remote-work sourcing rules.20 NYCRR §132.18(a)
R-NY201-3 — Itemized deduction limitation above $100,000 NYAGI
New York limits itemized deductions under NY Tax Law §615(f) for taxpayers with New York adjusted gross income above $100,000. The limitation phases out the itemized deduction through multiple income bands and requires a detailed computation under 20 NYCRR §112.3. This skill handles the simple case (standard deduction obviously superior) but refuses the complex case where the itemized deduction would materially benefit the taxpayer. Please consult a CPA to compute the NY itemized deduction limitation in detail.NY Tax Law §615(f); 20 NYCRR §112.3
R-NY201-4 — PTET election scenario
The New York Pass-Through Entity Tax (PTET) election under NY Tax Law Article 24-A applies to multi-owner pass-through entities (S corporations, LLCs taxed as partnerships, and general partnerships) that elect to pay state income tax at the entity level to bypass the federal SALT cap. The PTET is not available to disregarded single-member LLCs or bare sole proprietors because there is no separate pass-through entity to make the election. This skill covers only sole props and disregarded SMLLCs. If you are considering forming a multi-owner entity for PTET benefits, please consult a CPA to analyze the tradeoffs.NY Tax Law Article 24-A
R-NY201-5 — §174/§174A R&E material classification
NY Notice N-26-1 confirms New York decouples from the federal treatment of foreign and domestic R&E expenditures for tax years beginning on or after January 1, 2025. Material R&E positions require reviewer judgment on the §162 vs §174/§174A classification and the Form IT-225 A-225/S-221/S-222 modification schedule. This skill handles immaterial, clearly documented R&E positions by applying Position 5.15. Material or fact-sensitive positions are refused pending reviewer analysis. Please consult a CPA for the R&E classification and NY modification schedule. Trigger: R&E-adjacent costs have material dollar impact (more than $10,000) and the allocation between §162 ordinary expenses and §174/§174A R&E is fact-sensitive.NY Notice N-26-1; Form IT-225-I (2025)
R-NY201-6 — Credit for taxes paid to another state
The New York resident credit for taxes paid to another state or political subdivision under NY Tax Law §620 is a complex allocation exercise that requires determining the New York source and non-New York source components of income, computing the credit cap under the §620(e) limitation formula, and coordinating with the other state's return. This skill does not compute the NY §620 credit. Please consult a CPA to compute the resident credit — it is often materially valuable and should not be skipped.NY Tax Law §620; §620(e)
R-NY201-7 — Multi-state business activity or multi-zone MCTMT allocation
Multi-state business activity allocation under NY Tax Law §631 and MCTD zone allocation under NY Tax Law §800(b) both require Form IT-203-A (Business Allocation Schedule). This schedule is complex and requires detailed records of where each activity was performed. This skill assumes all activity is in a single location by virtue of the taxpayer's residency. Please consult a CPA for Form IT-203-A preparation.NY Tax Law §631; §800(b)
R-NY201-8 — Split-residence married couple
Split-residence married couples require careful residency analysis for each spouse and may require separate New York returns under NY Tax Law §651(b) even if the couple files jointly at the federal level. The filing status interactions are complex and often benefit from separate NY filings even when the federal filing is joint. This skill does not handle split-residence couples. Please consult a CPA to analyze the optimal NY filing approach.NY Tax Law §651(b)
R-NY201-9 — Amended return
Amended New York returns (Form IT-201-X) require reconciliation to the original filing, identification of each change, and careful handling of any federal amendments that flow through to the NY amendment. This skill prepares original returns only. Please consult an Enrolled Agent or CPA for NY return amendments.Form IT-201-X
R-NY201-10 — Decedent taxpayer or fiduciary return
Returns for decedent taxpayers require special handling under NY Tax Law §658(d) including the decedent indicator, appropriate signatures, and coordination with any estate return. Fiduciary returns for estates and trusts use Form IT-205, not Form IT-201. Both are outside this skill's scope. Please consult an Enrolled Agent or CPA specializing in decedent or fiduciary returns.NY Tax Law §658(d); Form IT-205
R-NY201-11 — Special condition codes (combat zone, nonresident noncitizen, SCRA military election)
Taxpayers qualifying for special condition codes on Form IT-201 Item G (combat zone, nonresident noncitizen, Servicemembers Civil Relief Act election, out-of-country extension, Ponzi-type fraudulent investment loss, installment payment agreement, split-Yonkers-residence joint filer) require specific handling that is outside this skill's standard workflow. Please consult a CPA familiar with the specific condition that applies.Form IT-201 Item G
R-NY201-12 — Minor with investment income (Form 8615 / kiddie tax)
Returns for minors with investment income subject to the federal kiddie tax rules (Form 8615 or parent's election via Form 8814) interact with NY in non-obvious ways. The child's investment income, when reported on the parent's return, is taxed at the parent's NY rate but subject to the $3,100 NY dependent standard deduction. This skill does not handle kiddie tax integration. Please consult a CPA for returns involving minors with significant investment income.Form 8615; Form 8814

NYAGI computation for Jake
$495,000 + $16,800 = $511,800Position 5.13
Taxable income computation for Jake
$511,800 − $8,000 − $0 = $503,800Position 5.17
NYC tax computation for Jake
NYC taxable income = $503,800. Using the NYC rate schedule for single filers (top bracket 3.876% applies to income above $50,000): ``` NYC tax = 3.078% × $12,000 + 3.762% × $13,000 + 3.819% × $25,000 + 3.876% × ($503,800 − $50,000) = $369.36 + $489.06 + $954.75 + $17,589.29 = $19,402.46 → $19,402 ``` Line 47a = $19,402.Position 5.22
NYC UBT credit computation for Jake
Jake paid $16,800 UBT. NYC taxable income $503,800 is well above $142,000, so the sliding scale is at the floor: credit rate = 23%. Credit = $16,800 × 0.23 = $3,864. Line 53 = $3,864.Position 5.24
MCTMT Zone 1 computation for Jake
NESE $540,248, all Zone 1. > $50,000. Line 54a = 0.60% × $540,248 = $3,241.49 → $3,241.Position 5.28
Check 28 — Residency gate passed
Position 5.1 residency gate returned "full-year NY resident" for the entire 2025 calendar year. If false: R-NY201-1 should have fired; verify refusal trace is present in the brief.Section 12
Check 29 — Federal AGI match
The federal AGI imported at Position 5.3 exactly matches the federal AGI on the upstream `us-federal-return-assembly` output. If false: arithmetic or import error; halt and reconcile.Section 12
Check 30 — NYAGI arithmetic balance
`Line 33 NYAGI == Line 19 Federal AGI + (sum of Lines 20-24 additions) − (sum of Lines 25-31 subtractions)` exactly. If false: arithmetic error in NYAGI computation; halt and recompute.Section 12
Check 31 — A-201 UBT add-back reconciles with NYC UBT skill output
If the taxpayer is a NYC resident and Position 5.8 includes an A-201 entry, the A-201 amount exactly matches the UBT deducted on federal Schedule C Line 23 AND matches the UBT paid per the `nyc-unincorporated-business-tax` skill's output. If false: cross-skill mismatch; flag as high reviewer attention.Section 12
Check 32 — Form IT-225 attached if modifications used
If any IT-225 code appears on the return, Form IT-225 is included in the attachment manifest. If false: structural error; produce Form IT-225.Section 12
Check 33 — Form IT-225 attached if decoupling used
If any IT-225 code appears on the return, Form IT-225 is included in the attachment manifest. If false: structural error; produce Form IT-225.Section 12
Check 34 — §174/§174A position documented
If Position 5.15 fired at all, the reviewer brief contains: (a) the federal §174/§174A amount, (b) the classification conclusion, (c) the IT-225 A-225 add-back if applicable, (d) the S-221 or S-222 subtraction, and (e) the later-year NY recovery schedule. If false: Position 5.15 documentation requirement violated; halt and complete the documentation.NY Notice N-26-1; Form IT-225-I (2025)
Check 35 — Correct tax computation method used
If NYAGI ≤ $107,650, the method is the tax table (if TI < $65,000) or the rate schedule (if TI ≥ $65,000). If NYAGI > $107,650, the method is the tax computation worksheet. If false: wrong method; produces wrong tax; halt and recompute.Section 12
Check 36 — Recapture worksheet band correctly selected
If the tax computation worksheet is used, the worksheet band matches the NYAGI range (e.g., $107,650-$157,650 for single filers with NYAGI in that range). If false: wrong worksheet band produces wrong tax; halt and recompute.Section 12
Check 37 — Deduction limitation refusal check
If NYAGI > $100,000 AND the itemized deduction exceeds the standard deduction, R-NY201-3 should have fired OR the standard deduction was taken. If false: §615(f) limitation not applied; halt and refuse or take standard.Section 12
Check 38 — NYC layer consistency
If the taxpayer is a NYC resident, Lines 47a through 54e are populated; if not a NYC resident, those lines are zero. If false: NYC layer mismatch with residency; halt and reconcile.Section 12
Check 39 — NYC UBT credit chain
If Line 53 > $0, then: (a) Form IT-219 is attached (b) IT-201-ATT Section C is populated (c) The credit amount traces to the `nyc-unincorporated-business-tax` skill's UBT-paid figure (d) The sliding-scale computation matches the Position 5.24 formula. If false: credit chain broken; halt and reconcile.Section 12
Check 40 — Yonkers layer consistency
If the taxpayer is a Yonkers resident, Line 55 (16.75% of Line 50) is populated; if a Yonkers nonresident with Yonkers earnings, Line 56 (0.50% with $3,000 exemption) is populated; if neither, both are zero. If false: Yonkers layer mismatch; halt and reconcile.Section 12
Check 41 — MCTMT zone determination correct
If the taxpayer's county is in the MCTD per §800(b), Line 54a (if Zone 1) or Line 54b (if Zone 2) is populated based on NESE exceeding the $50,000 per-individual-per-zone threshold. If the taxpayer's county is NOT in the MCTD (Albany, Buffalo, etc.), both lines are zero regardless of income. If false: MCTMT misapplication; halt and reconcile.Section 12
Check 42 — MCTMT rate correct per zone
Line 54a uses 0.60% (Zone 1); Line 54b uses 0.34% (Zone 2). These rates are not interchangeable. If false: wrong rate; halt and recompute.Section 12
Check 43 — Per-individual-per-zone threshold applied
On a joint return, each spouse's per-zone NESE is tested separately against the $50,000 threshold; the under-threshold spouse's base is excluded. If false: joint return MCTMT overcounts; halt and recompute per Position 5.28 note.Section 12
Check 44 — Tax layer arithmetic
`Line 61 == Line 46 + Line 58 + Line 59 + Line 60` exactly. If false: arithmetic error; halt and recompute.Section 12
Check 45 — Payment arithmetic
`Line 76 == (Lines 63-71 refundable credits) + Line 72 (NY WH) + Line 73 (NYC WH) + Line 74 (Yonkers WH) + Line 75 (estimated payments) + Line 75a (prior-year applied)` exactly. If false: arithmetic error; halt and recompute.Section 12
Check 46 — Balance due vs refund consistency
Exactly one of Line 77 (refund) and Line 78 (balance due) is non-zero, and the non-zero value equals `|Line 76 − Line 61|`. If false: arithmetic or logic error; halt and recompute.Section 12
