NYC Unincorporated Business Tax is a city-level tax that applies to businesses that are not incorporated. If you operate as a sole proprietor, a partnership, or an LLC that hasn’t elected to be taxed as a corporation, and you do business wholly or partly within New York City, you likely owe UBT. The tax rate is 4% of your unincorporated business taxable income.

This is separate from your federal and state income taxes. It’s a tax the City of New York imposes on top of everything else. You file it annually on Form NYC-202, and the due date follows the same schedule as your federal return. If you’re a sole proprietor, that means April 15. Partnerships and multi-member LLCs file by March 15.

There is a small deduction built into the calculation. You can subtract $5,000 from your unincorporated business taxable income before applying the 4% rate. There is also a full exemption if your total gross income from the business is $95,000 or less. Between $95,000 and $150,000 in gross income, the exemption phases out. Above $150,000, you owe UBT on the full amount minus the $5,000 deduction.

One important thing many business owners overlook is the UBT credit. If you’re a New York City resident, you can claim a partial credit on your personal NYC income tax return using Form NYC-210. This helps offset the double taxation that would otherwise happen when the same income gets hit by both UBT and personal income tax. The credit doesn’t eliminate UBT entirely, but it reduces the overall burden.

A lot of small business owners in the Bronx and across the five boroughs don’t realize UBT exists until they get a notice from the NYC Department of Finance. This is especially common among sole proprietors who handle their own taxes or who work with a preparer unfamiliar with city-level obligations. Federal and state returns might be perfectly filed while UBT goes completely missed year after year. Penalties and interest accumulate in the background.

If your business structure is unincorporated and you operate anywhere in NYC, UBT should be part of your annual tax planning. Your full-service bookkeeping process should track your gross income and taxable income in a way that makes filing straightforward when the time comes. Keeping clean books throughout the year means your accountant or tax preparer has the numbers they need to complete Form NYC-202 accurately.
