Frequently Asked Questions
How is self-employment tax calculated?+
Self-employment tax is 15.3% of your net self-employment income: 12.4% for Social Security (on the first $184,500 in 2026) plus 2.9% for Medicare (with no income limit). The IRS lets you calculate on 92.35% of net earnings, and you can deduct half of the SE tax from your gross income.
Do freelancers pay both self-employment tax and income tax?+
Yes. Self-employment tax covers Social Security and Medicare (the employer + employee portions). Federal income tax is separate and calculated on your taxable income after deductions. You pay both — but the SE tax deduction and business expense deductions reduce your income tax.
Can I deduct half of my self-employment tax?+
Yes. The IRS allows you to deduct 50% of your self-employment tax as an adjustment to income on your 1040. This deduction is automatic — you don't need to itemize to claim it.
