What New York City Tax Requirements Apply to Businesses?

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.

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.

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.

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.

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.

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.

For calendar-year taxpayers, the general annual filing deadlines are:

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.
