Frequently asked questions
How much tax do I pay on 1099 income?
As a 1099 worker, you pay 15.3% self-employment tax (12.4% Social Security + 2.9% Medicare) on 92.35% of your net earnings, plus federal income tax on your adjusted gross income. Most freelancers should set aside 25-30% of their gross income for taxes.
What is self-employment tax?
Self-employment tax is the freelancer's equivalent of FICA taxes (Social Security and Medicare). When you're employed, your employer pays half of these taxes. As a 1099 worker, you pay both halves — 15.3% total. However, you can deduct half of your SE tax as an above-the-line deduction on your income tax return.
When are quarterly estimated tax payments due?
Quarterly payments are due April 15, June 15, September 15, and January 15 of the following year. You may owe a penalty if you don't pay at least 90% of your current year's tax or 100% of last year's tax through estimated payments and withholding.
What can freelancers deduct?
Common deductions include home office expenses, vehicle mileage for business travel, equipment and software, internet and phone bills, professional development, business insurance, marketing costs, and professional services (accounting, legal). You can also deduct self-employed health insurance premiums and retirement contributions (SEP IRA, Solo 401k).
What is the QBI deduction and how does it apply to freelancers?
The Qualified Business Income (QBI) deduction under IRC §199A lets eligible self-employed taxpayers deduct up to 20% of their qualified business income. For 2025, the full deduction phases out above $197,300 single / $394,600 married filing jointly. Above the upper threshold ($241,950 / $483,900), sole proprietors with no W-2 wages typically lose the deduction entirely because the W-2 wage limit binds at zero — which is exactly why some high-income freelancers elect S-corp status.
When should a freelancer elect S-corp status?
Electing S-corp status (via Form 2553) lets you split your business income into a W-2 salary and pass-through distributions. Only the salary portion is subject to payroll tax (FICA), so you save the 15.3% self-employment tax on the distribution. The breakeven typically falls between $40,000–$80,000 of net profit, depending on admin overhead (payroll service + 1120-S filing) and your reasonable compensation level. At higher incomes, S-corp also helps unlock the QBI deduction by creating a W-2 wage base. Consult a CPA before electing — the IRS scrutinizes "reasonable salary" levels.
Your 1099 tax also depends on where you live.
