How much tax do freelance developers pay?

You owe 15.3% self-employment tax on 92.35% of net profit plus federal income tax at your bracket. For many developers, total federal tax lands around 25–35% of net profit depending on income and deductions.

Should a freelance developer form an S-corp?

Often worth considering once net profit is reliably above roughly $80,000–$100,000. You take a reasonable salary (payroll-taxed) and the rest as distributions that avoid the 15.3% SE tax. The savings usually outweigh added payroll and filing costs — confirm with a CPA.

What can freelance developers write off?

Hardware (Section 179), cloud hosting and servers, software licenses and IDE/SaaS subscriptions, a home office, internet, courses and certifications, and payment-processing fees. Ordinary, necessary business costs qualify.

Do I need to pay quarterly taxes as a freelance developer?

Yes, if you expect to owe $1,000 or more for the year. Estimated payments are due April 15, June 15, September 15, and January 15. Skipping them triggers IRS underpayment penalties even if you pay in full by April.
