How this New York self-employment tax calculator works
This calculator estimates your total tax on self-employment income in New York for 2026. It combines two distinct layers of tax:
- Federal self-employment tax (Schedule SE) — 15.3% on 92.35% of your net profit, split between Social Security (12.4%, capped at the $184,500 wage base) and Medicare (2.9%, no cap). An extra 0.9% Additional Medicare applies above $200,000 (single) or $250,000 (MFJ). The deductible half — 50% of the base SE tax — is then subtracted from your gross income to arrive at federal AGI.
- New York state income tax — New York taxes New York Adjusted Gross Income minus the NY standard deduction ($8,000 single / $16,050 MFJ / $11,200 HOH for 2025/2026). For W-2 employees, NY AGI approximates federal AGI. Pre-tax 401(k) deferrals and HSA contributions reduce federal AGI and therefore NY taxable income.
Step-by-step calculation
- Net earnings: Net profit × 92.35% = SE tax base.
- Federal SE tax: Social Security + Medicare + Additional Medicare (if applicable).
- Deductible half: ½ × (Social Security + Medicare) — deducted above the line on Form 1040.
- Federal AGI from SE: Net profit − deductible half.
- New York taxable income: Federal AGI minus the New York standard deduction ($8,000 single).
- New York income tax: Progressive brackets applied (up to 10.9% top rate).
Scope and limitations
What is excluded: Excludes New York City income tax (3.078%–3.876% for NYC residents) and Yonkers surcharge. NYC residents should add city tax on top of this estimate. NY SDI (State Disability Insurance) and PFML (Paid Family and Medical Leave) payroll contributions are also excluded. This calculator models a single Schedule C filer with no other income sources. It does not include QBI deduction (20%), health insurance deductions, retirement plan contributions, tax credits, or itemized deductions. Consult a tax professional for your full return.
Use this for planning, not filing. Every rate and threshold is pulled from official IRS, SSA, and NY Dept. of Taxation and Finance — 2026 tax rates (Chapter 59, Laws of 2025, Part A) publications and re-checked each January.

Frequently asked questions
What is New York's income tax rate on self-employment income?+
New York has nine income tax brackets ranging from 3.9% to 10.9% after 2025 Chapter 59 reforms reduced the lower five brackets by 0.1%. For a single self-employed person at $80,000 net profit, the NY marginal rate is 6.25%. New York City residents pay an additional NYC income tax (3.078%–3.876%) not included in this estimate. Source: New York Department of Taxation and Finance.
Does New York City have its own income tax on self-employment income?+
Yes. NYC residents pay a separate New York City income tax of 3.078% to 3.876% on top of New York State income tax. Combined with the NY State rates, a NYC freelancer earning $80,000 pays an effective combined NY State + NYC rate of roughly 10%–11%. This calculator shows the NY State income tax only — NYC residents should add their applicable NYC rate.
Did the 2025 New York tax law changes affect self-employment income?+
Yes. Chapter 59 of the 2025 New York Laws reduced the five lower income tax brackets by 0.1 percentage point each (effective for tax year 2025 forward). For example, the 6.85% bracket became 6.25%. The two highest brackets (9.65% and 10.9%) were not changed. These updated rates are what this calculator uses for 2026.
What is self-employment tax?+
Self-employment (SE) tax is the Social Security and Medicare tax paid by freelancers, 1099 contractors, and sole proprietors. Employees split these costs with their employer (7.65% each); when you work for yourself you pay both halves — 15.3% total — on 92.35% of your net profit. It is separate from, and on top of, federal and state income tax.
Do I also owe New York state income tax on my self-employment income?+
Yes. In addition to federal SE tax, New York taxes self-employment net profit as ordinary income. This calculator shows both: the federal SE tax (Social Security + Medicare) and the estimated New York state income tax side by side, so you can see your true combined tax bill.
Can I deduct half of my self-employment tax?+
Yes — from federal income tax. You can deduct one half of your Social Security and Medicare SE tax as an above-the-line adjustment to income on Form 1040. This deductible half also reduces your federal AGI, which in turn reduces your state taxable income in most states (except Pennsylvania, which taxes gross compensation regardless).
How can I lower my self-employment tax?+
SE tax is based on net profit (gross revenue minus business expenses), so every legitimate business deduction reduces both your SE tax and your state income tax. Common deductions include home-office use ($5/sqft simplified method), equipment and software (Section 179), business mileage, and professional services. The standard deduction and QBI deduction reduce income tax only — not SE tax.
When do I pay self-employment tax?+
SE tax is paid through quarterly estimated payments (Form 1040-ES), due April 15, June 16, September 15, and January 15 for the prior year's fourth quarter. If you expect to owe $1,000 or more in federal tax after withholding, you generally must pay quarterly to avoid the IRS underpayment penalty. Most states that tax SE income have parallel quarterly estimated payment requirements.
