Frequently Asked Questions
How much self-employment tax do I owe?
SE tax is 15.3% of your net income (after the 92.35% adjustment). On $100K, approximately $14,130. On $200K, approximately $26,130. Use the calculator above for your exact number.
What is the self-employment tax rate for 2025?
15.3% total: 12.4% Social Security (capped at $176,100) + 2.9% Medicare (no cap) + 0.9% Additional Medicare above $200K single / $250K married filing jointly.
Can I reduce my self-employment tax?
Yes. S-Corp election saves $7,000-$25,000/year by making distributions FICA-free. Business deductions reduce your net income. The 50% SE tax deduction lowers your income tax. See the S-Corp savings shown in the calculator.
Is self-employment tax the same as income tax?
No. SE tax (15.3%) funds Social Security and Medicare. Income tax (10-37%) funds general government. Both apply to self-employment income — combined rates can exceed 40%.
Do I get a deduction for self-employment tax?
Yes. 50% of your SE tax is deductible above-the-line under IRC section 164(f). This reduces your AGI and income tax. It does not reduce the SE tax itself.
