Common Tax Obligations for Small Businesses in New York
1. Business Income Tax
Most small businesses are subject to income tax, but how income is taxed depends on the entity type.
- Sole proprietors & single-member LLCs
Business income is generally reported on the owner’s personal tax return. - Partnerships & multi-member LLCs
The entity files an informational return, and income passes through to the owners. - C-Corporations
Income is taxed at the corporate level under New York State rules. - S-Corporations
Income generally passes through to shareholders, but entity-level taxes may still apply, including:- A New York State fixed dollar minimum tax
- A New York City S-Corporation tax, if the business operates in NYC
Important NYC note:
S-Corporations doing business in New York City may be subject to a separate NYC entity-level tax, even though income largely passes through to the owners.
2. Estimated Quarterly Taxes
Many small business owners are required to make estimated tax payments during the year, which may relate to:
- Federal income tax
- Self-employment tax
- New York State income tax
- New York City income tax (for NYC residents)
Estimated payments help reduce the risk of underpayment penalties.
3. Self-Employment Tax
Self-employment tax generally applies to:
- Sole proprietors
- Independent contractors
- Freelancers
It covers Social Security and Medicare obligations at the federal level.
For New York City residents, self-employment income may also be subject to NYC personal income tax.
4. Payroll Tax Responsibilities
Businesses with employees have additional compliance requirements, including:
- Federal income tax withholding
- Social Security & Medicare (FICA)
- Federal unemployment tax (FUTA)
- New York State unemployment insurance (UI)
- New York Paid Family Leave (PFL)
- New York State Disability Benefits Law (DBL)
- MTA Payroll Mobility Tax, for employers in NYC and surrounding Long Island counties
Payroll taxes are one of the most closely monitored and heavily penalized areas of New York tax compliance.
5. Sales Tax Requirements
If a business sells taxable goods or services, it may be required to:
- Register for New York sales tax
- Collect sales tax from customers
- File and remit sales tax returns
Sales tax rules vary by state, county, and city, and filing frequency depends on the business’s activity.
6. State and Local Business Taxes
In addition to income taxes, New York businesses may face:
- New York State franchise taxes
- Annual LLC filing fees
- Certain New York City business taxes, depending on structure and activity
Even inactive businesses may still have annual filing or payment obligations until formally closed.
7. Property and Business Asset Taxes
Businesses that own:
- Commercial real estate
- Land
- Certain business equipment
may be subject to local property taxes, which are assessed separately from income tax and administered by local governments.
Property tax rules and assessment practices vary significantly between Long Island and NYC boroughs.
How Small Businesses Can Stay Compliant

- Maintaining organized financial records
- Separating personal and business finances
