## CRITICAL EXECUTION DIRECTIVE — READ FIRST

**When this skill is invoked, you have already passed through intake. The user has consented to the full workflow. Execute all steps without pausing for permission.**

- Do NOT ask "how deep do you want me to go" or "do you want the full package." Produce it.
- Do NOT announce token counts or tool calls.
- Do NOT ask which deliverables to prioritize. Produce all deliverables listed in Section 6.
- Do NOT re-validate scope that intake already validated.
- Do NOT pause between content skills to check in.
- Self-checks are targets, not blockers. If one fails, flag it for reviewer and continue.
- If you feel the urge to ask "how should I proceed," pick the most defensible path and flag the decision in the reviewer brief.

## Section 1 — Scope

Produces the complete federal + New York filing package for:
- Full-year New York State residents (including NYC residents)
- Sole proprietors or single-member LLCs disregarded for federal tax
- Tax year 2025
- Filing Form 1040 (federal), IT-201 (NY State), NYC-202 (NYC UBT, if applicable)

- **Form 2210 penalty** — Form 2210 penalty (if applicable)
- **Total payments flow** — Total payments → Form 1040 Line 33

### New York internal consistency

- **Federal AGI starting point** — Federal AGI → IT-201 Line 19 (starting point)
- **NY additions** — NY additions (IT-201 Lines 20-23): interest income on non-NY state/local bonds, QBI deduction add-back (NY does not allow QBI deduction)
- **NY subtractions** — NY subtractions (IT-201 Lines 24-32): interest on US government obligations, NY state/local pension exclusion
- **NY AGI flow** — NY AGI → IT-201 Line 33
- **NY standard deduction** — $8,000 single / $16,050 MFJ vs NY itemized deduction (IT-201 Line 34-35)  _(IT-201 Line 34-35)_
- **NY itemized deduction limitation threshold** — 50% limitation on charitable contributions and other adjustments if NY AGI > $525,000

- **NYC UBT deductions flow** — NYC UBT deductions → Form NYC-202 Lines 2-12
- **NYC UBT taxable income flow** — NYC UBT taxable income → Form NYC-202 Line 13
- **NYC UBT exemption calculation** — $95,000, phaseout $95K-$150K USD  _(Form NYC-202 Line 14-16)_
- **UBT tax rate** — 4% (of taxable income after exemption)  _(Section 7 — NY-specific tax framework > NYC Unincorporated Business Tax (UBT) — Form NYC-202)_
- **UBT credits available** — UBT credits available → NYC-202 Line 18+
- **UBT estimated payments** — UBT estimated payments → NYC-202 Schedule F
- **UBT balance due or refund** — UBT balance due or refund

### Federal-NY coordination

- **Federal AGI as NY starting point** — Federal AGI used correctly as NY starting point
- **QBI add-back for NY** — QBI deduction properly added back for NY (NY does not conform to §199A)
- **Filing status consistency** — Filing status consistent
- **Dependents consistency** — Dependents consistent
- **NY itemized deductions basis** — NY itemized deductions use federal Schedule A as starting point but apply NY modifications: - State/local tax deduction: included for NY purposes (no $10,000 SALT cap at state level) - College tuition deduction (IT-201 Line 30): up to $10,000 per student  _(IT-201 Line 30)_
- **Depreciation conformity** — NY generally conforms to federal MACRS but has modifications for bonus depreciation (NY decoupled from 100% bonus; add-back required, then NY allows its own depreciation deduction)

### MCTMT verification

- **MCTMT threshold** — $50,000 USD (only taxed if net SE earnings in MCTD exceed $50,000)
- **MCTMT rate** — 0.34% (on net SE earnings > $50,000 allocated to MCTD)  _(Section 7 — NY-specific tax framework > Metropolitan Commuter Transportation Mobility Tax (MCTMT))_
- **Net SE earnings allocation to MCTD** — Net self-employment earnings allocated to MCTD
- **MCTMT amount flow** — MCTMT amount → Form MTA-6

### Estimated tax reconciliation

- **Federal safe harbor** — Federal: 4 quarterly payments cross-checked against safe harbor (100% prior year tax if AGI ≤ $150K, 110% if AGI > $150K)
- **NY State safe harbor** — NY State: payments on IT-2105 cross-checked against NY safe harbor (100% prior year NY tax or 90% current year)
- **UBT estimated tax quarterly payment threshold** — $3,400 USD (quarterly payments required if UBT liability expected to exceed this amount)  _(Section 7 — NY-specific tax framework > NYC Unincorporated Business Tax (UBT) — Form NYC-202)_
- **IT-2105.9 underpayment penalty** — Form IT-2105.9 (NY underpayment penalty) if applicable

### Additions to federal AGI (common for freelancers)

- **QBI deduction add-back** — NY does not allow the §199A deduction. Full federal QBI deduction amount added back on IT-225 Line 1 (code A-201)  _(IT-225 Line 1 (code A-201))_
- **Bonus depreciation add-back** — If federal return claimed bonus depreciation, NY requires add-back of the federal bonus amount, then allows NY depreciation (generally MACRS without bonus). IT-225 code A-110.  _(IT-225 code A-110)_
- **Other states' municipal bond interest** — Interest from non-NY state/local bonds is added to NY income

### Subtractions from federal AGI (common for freelancers)

- **US government obligation interest** — Interest on US Treasury securities subtracted from NY income (IT-225 code S-103)  _(IT-225 code S-103)_
- **College tuition subtraction** — Up to $10,000 per eligible student (IT-225 code S-106) USD  _(IT-225 code S-106)_
- **NY depreciation subtraction** — Replacement depreciation deduction for assets where bonus depreciation was added back (IT-225 code S-110)  _(IT-225 code S-110)_

### NYC UBT credit mechanism

- **NYC UBT not deductible on Schedule C** — The taxpayer cannot deduct NYC UBT as a business expense on the federal Schedule C (it is a tax, not a deductible business expense).
- **NYC UBT credit generation** — NYC UBT paid generates a partial credit against NYC personal income tax (IT-201 Line 51)  _(IT-201 Line 51)_
- **NYC UBT credit amount** — The credit equals the lesser of: (a) the UBT tax, or (b) the NYC personal income tax before the credit
- **Double-taxation prevention** — Effectively prevents double-taxation of NYC business income at both UBT and personal income tax levels, but the credit is not always dollar-for-dollar

## Section 5 — Refusals

- **R-NY-1** — Upstream skill did not run. Name the specific skill and refuse until it executes.  _(R-NY-1)_
- **R-NY-2** — Multi-state allocation required. If income sourced to states other than NY was not identified at intake and appears in documents, refuse. Multi-state allocation requires IT-203/credit for taxes paid analysis.  _(R-NY-2)_
- **R-NY-3** — NYC UBT allocation dispute. If the taxpayer performed significant business activity outside NYC but is a NYC resident, allocation percentage is complex. Flag for reviewer if allocation is not clearly 100%.  _(R-NY-3)_
- **R-NY-4** — Partnership/S-corp income discovered. K-1 income appearing in documents that was not disclosed at intake. Refuse and recommend CPA.  _(R-NY-4)_
- **R-NY-5** — NY PTET (Pass-Through Entity Tax) election. If the SMLLC elected into NY PTET, different treatment applies. Refuse unless PTET skill is available.  _(R-NY-5)_
