# Review kit: Nyc Unincorporated Business Tax

Thank you for reviewing this Guide. This kit is one file with three parts: how
to use it, an interview prompt for your AI, and the Guide itself.

## How to use this kit (3 steps, about 15 minutes)

1. Open the AI you already use (ChatGPT, Claude, Gemini, anything that reads
   markdown) and paste in everything from "INTERVIEW PROMPT" below, including
   the Guide at the end.
2. Your AI interviews you like a colleague, one question at a time. Just talk:
   war stories, walk-throughs, the mistakes you catch. No writing required.
3. Your AI writes your answers up as a single markdown file. Hand it back at
   openaccountants.com/skills/nyc-unincorporated-business-tax/handback (also linked from the Guide
   page: "Hand back your file"). What you added is published under your name
   and credential.

If your AI cannot produce the exact output format, hand back whatever you have:
a revised Guide file, a worksheet, or plain notes. We take those too, and a
person reviews them by hand. The format below is the one we can apply straight
away.

# INTERVIEW PROMPT (paste from here down into your AI)

You are interviewing a practising accountant about how they actually do the
work covered by the attached Guide ("Nyc Unincorporated Business Tax", slug `nyc-unincorporated-business-tax`).
Interview them like a colleague doing a handover. Do not lecture. Ask ONE
question at a time and wait for the answer. Chase war stories and specifics:
what kind of client, which portal step, how big the penalty was.

The rates, thresholds, and citations are our job; we refresh those from primary
sources. Capture ONLY what is NOT derivable from law:

- order of operations, and what a wrong order corrupts
- what to ask a client before computing anything
- what to assume when a fact is unknown, and how it gets flagged
- the most-missed traps, with penalty size and who falls in
- how the portal or filing channel actually behaves
- what has to reconcile before anyone signs
- when to refuse the work and hand it to a human specialist

If the accountant corrects a rate, threshold, or deadline in the Guide along
the way, record it in the FACT CORRECTIONS table, but do not steer the
interview toward numbers.

## Questions to work through

Ask these in order, one at a time. Skip any the accountant has already covered;
follow up where a story has specifics worth pinning down. Each question is
tagged with the method slot(s) it feeds.

1. [intake_questions] A founder walks in wanting "a company". What do you ask before recommending a structure?
2. [judgment_rule] Tell me about a time the default structure was wrong for someone. What tipped you off?
3. [edge_case] [trap] What do foreign founders never know about local requirements: resident directors, notarised documents, KYC?
4. [filing_mechanics] Walk me through the registration portal itself. Which pieces happen automatically, which need separate applications, and in what order?
5. [trap] What do people set wrong at incorporation that's expensive to fix later?
6. [judgment_rule] Which registrations do you deliberately NOT do at formation, and when do you tell clients to wait?
7. [filing_mechanics] [trap] What's the compliance calendar you set up on day one, especially the deadlines that disqualify directors or deactivate registrations?
8. [evidence] [sequence] What's your first-90-days checklist after the certificate arrives: bank account, share certificates, registers?
9. [trap] Have you seen a company struck off or a director disqualified? What was the chain of misses?
10. [scope_gate] When do you refuse a formation outright?
11. [judgment_rule] What does "we plan to raise money" change about how you set the entity up?
12. [handback_protocol] What's in the formation pack you hand the founder at the end?

## Method slots (for tagging the write-up)

- `scope_gate` (Scope gate and refusals): when to stop and send the client to a human
- `sequence` (Order of operations): what order to do things in, and what a wrong order corrupts
- `intake_questions` (Client intake questions): what to ask a client before computing
- `evidence` (Documents and evidence): which documents to insist on, and what is draft-grade vs file-grade
- `judgment_rule` (Judgment rules): how a practitioner actually picks when the law allows two routes
- `conservative_default` (Conservative defaults): what to assume when a fact is unknowable at draft time
- `trap` (Traps and most-missed items): the mistakes everyone makes, what they cost, and who falls in
- `filing_mechanics` (Portal and filing mechanics): how submission actually works: channel, order, what locks
- `cross_check` (Cross-checks before signing): what has to reconcile with what before delivery, and how close is close enough
- `pattern_library` (Pattern library): how messy real-world data (bank lines, payout platforms) maps to tax categories
- `edge_case` (Edge-case playbook): the client situations that change the method, not just the numbers
- `unsettled_law` (Unsettled-law flags): what not to finalise right now, and why
- `handback_protocol` (Hand-back protocol): what the finished working paper contains and who reviews it

## Output format: oa-handback v1

When the interview is done, write the answers up as ONE markdown file in
exactly this shape. Fill in the reviewer's real name, credential, and email
(ask for them at the end if they have not come up). Every method block gets a
`### [method:<slot>]` heading where `<slot>` is one of the 13 slot ids
above. Keep `guide_slug` and `guide_version` exactly as given. Omit any
section the interview produced nothing for, but keep the headings that remain
exactly as shown. The `fact_key` column may be left blank when unknown.

- **Estimated tax payments requirement** — Quarterly estimated payments are required if the expected UBT liability is $3,400 or more. Payment dates follow the same schedule as NY state estimated tax (April 15, June 15, September 15, January 15).  _(NYC-202EIN instructions)_

## Section 3 -- Rates and thresholds

**Rates and thresholds**  _(NYC Admin Code §11-503(a); §11-510(a); NY Tax Law §1310(e); Form IT-219; NYC-202EIN instructions)_

| Item | Amount | Source |
| --- | --- | --- |

- **Estimated tax threshold** — $3,400 expected annual UBT liability  _(NYC-202EIN instructions)_

### Exemption phase-out computation

**Exemption phase-out computation**  _(NYC Admin Code §11-510(a))_

| Taxable income | Exemption | Tax |
| --- | --- | --- |
| $95,000 or less | $95,000 (full) | $0 |
| $120,000 | $95,000 - ($25,000 / 2) = $82,500 | ($120,000 - $82,500) x 4% = $1,500 |
| $150,000 | $95,000 - ($55,000 / 2) = $67,500 | ($150,000 - $67,500) x 4% = $3,300 |
| $190,000 or more | $0 (fully phased out) | Taxable income x 4% |

- **Phase-out mechanism** — The $95,000 exemption is reduced by $1 for every $2 of taxable income exceeding $95,000.  _(NYC Admin Code §11-510(a))_

## Section 4 -- Computation rules (Step format)

### Step 1: Determine if UBT applies

- **UBT applicability tests** — The taxpayer must be carrying on a trade, business, profession, or occupation wholly or partly within NYC. Key tests: 1. Is there a profit motive? (Hobby income is not subject to UBT.) 2. Is the business conducted in NYC? (Physical presence, not just customers.) 3. Is the individual an employee or an independent contractor? (Employees are not subject to UBT for their employment income.)

### Step 2: Compute unincorporated business gross income (NYC-202, Line 1)

- **Gross income computation** — Start with gross income from the business: - Schedule C gross income (for sole proprietors) - Include all business income attributable to NYC operations - Include gains from business property

### Step 3: Compute unincorporated business deductions (NYC-202, Lines 2-13)

- **Deduction rules** — Allowable deductions mirror federal Schedule C deductions with these exceptions: - **No deduction for:** salaries paid to the owner, distributions to owner, federal/state/local income taxes (including UBT itself). - **Add back:** owner's health insurance deduction, retirement plan contributions for the owner (these are personal deductions, not business deductions for UBT).

### Step 4: Compute unincorporated business taxable income (NYC-202, Line 14)

- **Taxable income formula** — Gross income - allowable deductions = unincorporated business taxable income (before exemption).

### Step 5: Apply the $5,000 specific exemption

- **Specific exemption** — A specific exemption of $5,000 is allowed against net income. If the business was carried on for a short tax year, prorate the exemption under the NYC form instructions.

### Step 6: Compute tax before business tax credit

- **Tax before credit formula** — (Taxable income after the specific exemption) x 4% = UBT before business tax credit.

### Step 7: Apply the business tax credit

- **Business tax credit rules** — - If tax before credit is $3,400 or less, the credit equals the full tax and no UBT is due before other credits. - If tax before credit is $5,400 or over, no business tax credit is allowed. - If tax before credit is over $3,400 but under $5,400, credit = tax x ($5,400 - tax) / $2,000.

### Step 8: Compute net UBT due

- **Net UBT due formula** — Tax before business tax credit - business tax credit - other allowable credits = net UBT due.

### Step 9: Compute IT-219 credit (for NYC residents)

- **IT-219 credit mechanics** — The full amount of UBT paid is available as a credit against NYC personal income tax via Form IT-219. This credit: - Is limited to the NYC personal income tax liability (cannot create a refund) - Flows to Form IT-201-ATT, Line 53 (NYC resident tax credit) - Effectively prevents double taxation of NYC business income at both the UBT and personal income tax levels

### Step 10: File and pay

- **Filing and payment** — - File NYC-202 (or NYC-202S) with NYC Department of Finance. - Pay any balance due. - Retain confirmation for reviewer brief.

## Section 5 -- Edge cases and special rules

### E-1: Freelancers and independent contractors

- **Freelancer UBT nexus** — A freelancer who provides services in NYC is subject to UBT if their NYC business gross income exceeds $95,000. Simply having clients in NYC may be sufficient nexus if the work is performed in NYC.

### E-2: Work-from-home in NYC

- **Work-from-home NYC sourcing** — If a freelancer works from home in NYC, the home office IS in NYC, and all income earned from that home office is NYC-source business income for UBT purposes.

### E-3: Mixed NYC/non-NYC income

- **Business allocation percentage** — If the business operates both inside and outside NYC, the taxpayer must allocate income using the business allocation percentage. This is computed on Schedule C of Form NYC-202 using a formula based on property, payroll, and gross receipts in NYC vs. everywhere. This skill handles only 100% NYC businesses; allocation is out of scope.

### E-4: The IT-219 credit is critical

- **IT-219 credit economic effect** — NYC residents who pay UBT and also owe NYC personal income tax receive a full credit for UBT paid via Form IT-219. This means the economic burden of UBT for NYC residents is reduced (often to zero additional tax) because the credit offsets NYC personal income tax. However, the credit cannot exceed the NYC personal income tax, so if UBT exceeds NYC personal income tax, the excess UBT is a net cost.

### E-5: Hobby vs. business

- **Hobby vs business standard** — Activities not engaged in for profit (hobbies) are not subject to UBT. The IRS presumption (profit in 3 of 5 years) is a useful guideline but is not the UBT standard. NYC follows federal characterization of the activity.

### E-6: Multiple businesses

- **Combining multiple businesses** — If a taxpayer operates multiple unincorporated businesses in NYC, all businesses are combined on a single NYC-202 return. Separate NYC-202 forms are not filed for each business.

### E-7: Simplified return (NYC-202S)

- **NYC-202S eligibility** — If gross income from the business is $250,000 or less AND the taxpayer has no employees, no motor vehicle expenses, and no depreciation deductions, Form NYC-202S (simplified) may be used instead of the full NYC-202.

## Section 6 -- Test suite

### Test 1: Income below exemption

**Input:** Freelancer with $80,000 NYC business gross income.
**Expected:** Below $95,000 threshold. No UBT due. No filing required (gross income <= $95,000).

### Test 2: Income in phase-out range

**Input:** Freelancer with $130,000 taxable business income, all NYC.
**Expected:** Excess: $130,000 - $95,000 = $35,000. Exemption reduction: $35,000 / 2 = $17,500. Allowable exemption: $95,000 - $17,500 = $77,500. Taxable after exemption: $130,000 - $77,500 = $52,500. UBT: $52,500 x 4% = $2,100.

### Test 3: Income above phase-out

**Input:** Freelancer with $200,000 taxable business income, all NYC.
**Expected:** Exemption fully phased out ($0). UBT: $200,000 x 4% = $8,000.

### Test 4: IT-219 credit

**Input:** Same as Test 3. NYC personal income tax: $6,500. UBT paid: $8,000.
**Expected:** IT-219 credit: limited to $6,500 (cannot exceed NYC personal income tax). Net UBT cost: $8,000 - $6,500 = $1,500.

### Test 5: Simplified return eligibility

**Input:** Freelancer with $100,000 gross income. No employees, no vehicle, no depreciation.
**Expected:** Eligible for NYC-202S. Must still compute exemption phase-out.

## Section 7 -- Prohibitions

- **P-1** — Do NOT deduct the owner's salary, draws, or distributions when computing UBT taxable income.
- **P-2** — Do NOT deduct federal, state, or local income taxes (including UBT itself) from UBT income.
- **P-3** — Do NOT claim the IT-219 credit in excess of the NYC personal income tax liability.
- **P-4** — Do NOT apply the UBT to employment income. Employees are not subject to UBT.
- **P-5** — Do NOT file separate NYC-202 returns for multiple businesses. Combine all businesses.
- **P-6** — Do NOT allocate income between NYC and non-NYC without using the business allocation percentage schedule. This skill covers only 100% NYC businesses.

## Section 8 -- Self-checks

Before delivering output, verify:

- [ ] Business activity is in NYC (not just clients in NYC)
