Estimate your total tax burden as a freelancer or self-employed worker, including SE tax and quarterly payments.
As a freelancer or independent contractor, you pay self-employment (SE) tax of 15.3% (12.4% Social Security + 2.9% Medicare) on top of federal income tax. You can deduct half of the SE tax from your gross income when calculating income tax. You're also required to pay quarterly estimated taxes to avoid penalties.
Q1 (Jan–Mar): due April 15. Q2 (Apr–May): due June 17. Q3 (Jun–Aug): due September 16. Q4 (Sep–Dec): due January 15, 2025. Missing these dates results in underpayment penalties from the IRS.
Freelancers can deduct legitimate business expenses: home office (simplified method: $5/sq ft up to 300 sq ft), computer and equipment, internet and phone (business %), software subscriptions, professional development, health insurance premiums, and retirement contributions (SEP-IRA up to 25% of net income).
