- Self-employment tax is 15.3% — 12.4% Social Security plus 2.9% Medicare — on 92.35% of your net profit.
- The Social Security part stops at the $176,100 wage base for 2025; Medicare has no cap.
- Half of your self-employment tax is deductible, which lowers your income tax.
How the self-employment tax calculator works
Enter your net self-employment profit, your filing status, any W-2 wages this year, and any other income. The calculator works out your self-employment earnings — 92.35% of your net profit, as on Schedule SE — then applies 12.4% Social Security up to the $176,100 wage base for 2025 and 2.9% Medicare, plus the 0.9% Additional Medicare Tax where it applies. It then deducts half of that self-employment tax, subtracts the 2025 standard deduction, applies the federal income tax brackets, and shows your self-employment tax, income tax, total tax, and quarterly estimated payment.
This is an estimate for planning only. It is not the IRS self-employment tax calculation and it is not tax advice. State tax, business deductions already taken on Schedule C, and other credits are not included. If your situation is complex, check with a tax professional.
What affects your self-employment tax
Your net profit, your filing status, any W-2 wages you also earned, and your other income all change the result. A higher profit means more self-employment tax, but once your combined earnings pass the $176,100 Social Security wage base, only the 2.9% Medicare part keeps growing, so the effective rate falls.
