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.

Estimate only — not tax advice. TrainedBooks does bookkeeping, not tax filing. This is a simplified model to help you plan a set-aside; your actual taxes depend on credits, deductions, other income, and your state. Consult a tax professional before you file. Based on the 2025 IRS / SSA figures (the return most self-employed people file in early 2026).

What this calculator assumes

We keep the model transparent on purpose. Here's exactly what goes into your number, using the 2025 figures.

  • Self-employment tax of 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of your net profit.

  • The 12.4% Social Security portion is capped at the 2025 wage base of $176,100; the 2.9% Medicare portion has no cap.

  • Federal income tax from the 2025 brackets, applied to your profit minus the standard deduction and minus half of your self-employment tax (which is deductible).

  • An optional flat state effective rate applied to your profit. No QBI deduction, credits, or other household income are modeled.

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.
