What this calculator does
This calculator estimates the full tax on freelance, gig or 1099 income for someone living in New York City: self-employment tax for Social Security and Medicare, the extra federal income tax the profit causes, and New York tax. It also shows a quarterly estimated payment and the share of each dollar to set aside.
NYC has a large freelance workforce, and the Freelance Isn't Free Act gives independent workers the right to a written contract and timely payment. Self-employed residents pay NYC resident income tax on their profit, and the city's Unincorporated Business Tax (4%) can apply once business gross income exceeds $95,000.
How to use it
- Enter net profit — revenue minus business expenses, the number on Schedule C.
- Add any W-2 wages from a job this year so the tool can figure your bracket and Social Security limit.
- Choose your filing status.
- Add retirement contributions to a SEP-IRA or Solo 401(k), which lower income tax but not self-employment tax.
The formula
Self-employment tax = net profit × 92.35% × (12.4% Social Security up to the $184,500 wage base, minus any W-2 wages, + 2.9% Medicare, + 0.9% Additional Medicare above $200,000 single). Half of the SE tax is deductible. Federal and state income tax on the business is the tax on (wages + profit − half SE tax − retirement) minus the tax on wages alone. Quarterly estimate = total ÷ 4.
Worked example for New York City
A single freelancer in New York City with $80,000 of net profit and no other job:
| Item | Amount |
|---|---|
| Net profit (Schedule C) | $80,000 |
| Net earnings for SE tax (x 92.35%) | $73,880 |
| Social Security part (12.4%) | $9,161 |
| Medicare part (2.9% + 0.9% over threshold) | $2,143 |
| Deduction for half of SE tax | -$5,652 |
| Retirement contribution (SEP/Solo 401k) | $0 |
| Total estimated tax on this income | $24,695 |
About $6,174 per quarterly estimated payment · set aside 30.9% of profit.
What affects freelance taxes in New York City
New York City is the only city in this group that adds its own resident income tax. A New Yorker pays federal tax, New York State tax (graduated from 3.9% up to 10.9%) and NYC tax (3.078% to 3.876%). The city tax is based on where you live, not where you work, so a New Jersey or Westchester commuter working in Manhattan does not pay it, while a Brooklyn resident working remotely for an out-of-state company does.
Business expenses are the biggest lever: every legitimate expense lowers both self-employment tax and income tax. Home office, equipment, software, health insurance premiums for the self-employed and part of your phone bill are common deductions. Retirement contributions lower income tax only.
Common mistakes and tips

- Missing quarterly deadlines (usually April 15, June 15, September 15 and January 15), which can bring an underpayment penalty.
- Mixing personal and business money, which makes expenses hard to prove.
- Forgetting the qualified business income deduction, which can lower federal tax for many freelancers (not included in this estimate).
- Overlooking local business taxes and registrations in New York City — see the note in the results.
