How much should a freelancer set aside for taxes?
Quick answer
Most freelancers and sole proprietors should set aside about 25–30% of their net self-employment income for taxes — that covers the 15.3% self-employment tax (Social Security + Medicare) plus federal income tax. Your real number depends on your profit, filing status, and state, so it can be lower or higher.

Self-employment taxes — FAQ
How much should I set aside for taxes as a freelancer?
A common rule of thumb is 25–30% of your net self-employment income, which covers self-employment tax (15.3%) plus federal income tax for most people. But the right number depends on your profit, filing status, and whether your state has an income tax — the calculator above gives you a personalized set-aside percentage and the dollar amount.
When are quarterly estimated taxes due?
For the 2025 tax year, federal estimated-tax payments are generally due April 15, 2025 (Q1), June 16, 2025 (Q2), September 15, 2025 (Q3), and January 15, 2026 (Q4). If a date falls on a weekend or holiday, it moves to the next business day. You pay estimated taxes if you expect to owe at least $1,000 when you file.
What is self-employment tax?
Self-employment tax is the Social Security and Medicare tax that self-employed people pay on their net earnings — 15.3% total (12.4% Social Security up to the annual wage base, plus 2.9% Medicare with no cap). It's applied to 92.35% of your net business profit. Employees split this with an employer; when you're self-employed, you cover both halves, though you can deduct half of it on your income taxes.
