Quick answer

If you're one of America's freelance web developers, you're self-employed for taxes: you owe the 15.3% federal self-employment tax on your net profit, plus federal and state income tax. The upside is a long list of deductions โ€” track them and your bill drops fast. On $75,000 of net profit, self-employment tax alone is about $10,597 before those deductions.

Do freelance web developers pay self-employment tax?

Yes. If you earn money in this line of work without an employer withholding taxes for you, you're self-employed in the eyes of the IRS. That means the 15.3% self-employment tax (12.4% Social Security + 2.9% Medicare) on your net profit, on top of federal and state income tax. It's the same rate in every state โ€” see how self-employment tax works and your state's income-tax breakdown. Half of your SE tax is deductible, and most freelance web developers also qualify for the 20% Qualified Business Income deduction.

What tax forms do freelance web developers get?

Clients paying $600+ send a 1099-NEC; some platforms send a 1099-K. All development income is taxable.

How much should freelance web developers set aside for taxes?

A safe rule of thumb is 25โ€“30% of your net profit, set aside as you go and paid to the IRS four times a year as estimated quarterly taxes. Skipping quarterly payments can mean an underpayment penalty. The exact percentage depends on your income, deductions, and state.
