1. Which Businesses Must Pay New York City Tax?
New York City's business income taxes generally depend on a company's activities, income sources, and tax classification. Forming a company outside NYC does not necessarily remove its city tax obligations.
Business Activities and Economic Nexus
Under NYC Administrative Code §11-653, a corporation may be subject to Business Corporation Tax (BCT) when it conducts business, employs capital, maintains an office, or owns or leases property in the city.
Physical presence is not always necessary. For tax years beginning on or after January 1, 2024, corporations generally meet the BCT economic nexus threshold when NYC-sourced receipts reach $1,128,000.
Special rules apply to certain unitary groups. A corporation with at least $11,000 in NYC receipts may meet the economic nexus test when its qualifying group reaches the $1,128,000 aggregate threshold.
Registration Versus Tax Liability
Registering a company in New York State does not, by itself, determine NYC business tax liability. A corporation organized in another state may still meet the city's taxable activity or receipts requirements.
Partnerships and sole proprietors follow different rules. NYC Administrative Code §11-503 generally imposes Unincorporated Business Tax (UBT) on qualifying businesses conducted wholly or partly within the city. Businesses with operations across jurisdictions must evaluate each applicable tax separately.
2. How Are Corporations, Llcs, and Partnerships Taxed?
The NYC Department of Finance administers separate business income taxes. Federal tax classification helps determine which city tax applies, although specific exemptions and entity rules may change the result.
| Business classification | Applicable NYC tax | Common return |
|---|---|---|
| Federal C corporation | Business Corporation Tax | NYC-2 |
| Federal S corporation | General Corporation Tax | NYC-3L or NYC-4S |
| Partnership | Unincorporated Business Tax | NYC-204 |
| Sole proprietor | UBT, if applicable | NYC-202 |
| LLC | Depends on tax classification | Varies |

Business Corporation Tax and General Corporation Tax
Most taxable federal C corporations fall under BCT for tax years beginning on or after January 1, 2015. Federal S corporations generally remain subject to General Corporation Tax (GCT).
New York City does not provide its own S corporation election and does not recognize a New York State S corporation election for city tax purposes. A business should therefore review its federal status before selecting a city return.
Entity conversions, mergers, or changes in tax elections may require a separate review of corporate tax compliance.
Llcs and Unincorporated Business Tax
An LLC taxed as a partnership generally follows UBT rules. For a single-member LLC disregarded for federal income tax purposes, the owner's classification ordinarily determines the applicable city tax treatment.
An LLC electing corporate taxation may instead fall under BCT or GCT.
UBT generally imposes a 4% tax on taxable income allocated to NYC. However, qualifying investment activities and certain real property activities may be excluded. Rental income should be evaluated based on the applicable exclusions and the nature of the business activities.
3. How Is NYC Business Tax Calculated?
NYC tax calculations use rules that differ from federal and New York State income tax requirements. The amount owed depends on the applicable tax base, allocation method, and available credits.
Income Allocation and Business Receipts
Businesses operating in multiple jurisdictions must determine how much income belongs to NYC.
Under Administrative Code §11-654.2, BCT generally uses receipts-based apportionment. Sales of tangible goods commonly follow destination-based sourcing, while services generally use customer-benefit sourcing rules.
UBT follows separate allocation requirements. Businesses should maintain transaction records, revenue reports, and documentation supporting their NYC income calculations.
Tax Credits and Minimum Payments
UBT provides a credit that eliminates calculated tax liability of $3,400 or less. A partial credit applies when liability exceeds $3,400 but remains below $5,400.
BCT generally compares tax calculations based on business income, business capital, and a fixed-dollar minimum tied to NYC receipts, subject to applicable rules and limitations.
A corporation may owe a minimum tax even when it reports little or no taxable income. Taxpayers should check applicable credits and minimum requirements before determining their final payment.
4. What Are the NYC Business Tax Filing Requirements?
Businesses must file the appropriate city returns and retain records supporting their tax classification, income, and deductions. Filing deadlines differ between corporate and unincorporated business taxes.
Filing Deadlines and Extensions
For calendar-year taxpayers, the general annual filing deadlines are:
| NYC Tax Category | General Deadline |
|---|---|
| Business Corporation Tax | April 15 |
| General Corporation Tax | March 15 |
| UBT for partnerships | March 15 |
| UBT for individuals | April 15 |

- General DeadlineApril 15

- General DeadlineApril 15
Fiscal-year businesses generally follow the corresponding third- or fourth-month filing rules. Deadlines falling on weekends or legal holidays generally move to the next business day.
Eligible taxpayers may request an automatic six-month filing extension using Form NYC-EXT. The extension does not extend the deadline for paying taxes, and applicable estimated tax payments must be made separately.
5. Records and Electronic Filing
Businesses should prepare documents that substantiate their reported income and tax treatment:
- Federal tax returns and entity classification records
- NYC receipts and customer-location reports
- Partnership agreements and ownership records
- Business leases and property records
- Income allocation schedules and prior tax returns
- Estimated payments, credits, and exemption records
These records support the selected tax classification, the amount of income allocated to NYC, and any claimed adjustments.
NYC requires electronic filing for covered business tax returns when the applicable mandate applies. Businesses should check the Department of Finance's Business Tax e-File requirements and available forms before submission.
