I am self-employed. How much state tax, if any, would i have to pay in the state of New York?

Answer 1

It depends what your profit in the business is. Just like on your federal return, the more you make the more income tax you'll pay. NY has a "progressive" state tax. The rates go from 4% to 7%, but there are also some local income taxes that depend on where you work and live. But you won't have to pay self-employment tax to NY.

Answer 2

State tax on your net income will be the same as if you made that same amount as an employee.
