Frequently Asked Questions
How much self-employment tax will I owe?
Self-employment tax is 15.3% applied to 92.35% of your net profit β 12.4% for Social Security plus 2.9% for Medicare. On $60,000 of net profit, that's roughly $8,478. Enter your numbers above for your exact 2025 estimate.
Why is SE tax based on 92.35% of net earnings?
The IRS lets you reduce your net profit by 7.65% (an adjustment that mirrors the employer-side payroll tax deduction employees effectively get) before applying the 15.3% rate. So you multiply net profit by 0.9235 first, then apply the tax.
Is there a cap on self-employment tax?
Only on the Social Security portion. For 2025, the 12.4% Social Security tax applies to net earnings up to the $176,100 wage base (reduced by any W-2 wages already taxed for Social Security). The 2.9% Medicare portion has no cap and applies to all of your net earnings.
Can I deduct part of my self-employment tax?
Yes. You can deduct half of your self-employment tax as an above-the-line deduction on your income tax return. This reduces your adjusted gross income β though it does not reduce the SE tax itself.
Is self-employment tax the same as income tax?
No β they're separate. SE tax covers Social Security and Medicare for the self-employed. You also owe regular federal (and possibly state) income tax on your profit. Many self-employed people pay both through quarterly estimated tax payments.
Who has to pay self-employment tax?
Generally anyone with $400 or more of net earnings from self-employment β freelancers, gig workers, independent contractors (1099), and sole proprietors. It covers the Social Security and Medicare contributions an employer would otherwise split with you.
