How 1099 and Self-Employment Taxes Work
When you receive a 1099 instead of a W-2, no taxes are withheld from your payments. You are responsible for paying both the employee and employer portions of Social Security and Medicare -- a combined 15.3% self-employment tax on net earnings (12.4% Social Security up to the wage base of $176,100 in 2026, plus 2.9% Medicare with no cap).
On top of self-employment tax, you owe federal income tax on your net profit after deducting business expenses. The IRS lets you deduct half of your self-employment tax as an above-the-line adjustment, which reduces your taxable income slightly.
Quarterly Estimated Tax Payments
The IRS expects freelancers to pay estimated taxes four times a year using Form 1040-ES. Due dates are typically April 15, June 15, September 15, and January 15 of the following year. If you underpay, you may owe an estimated tax penalty -- generally if you owe more than $1,000 at filing time and did not pay at least 90% of the current year's tax or 100% of last year's tax (110% if AGI exceeded $150,000).
A simple approach: set aside 25-30% of each payment you receive in a separate savings account. This covers federal income tax, self-employment tax, and gives a buffer for state taxes.
Common 1099 Tax Deductions
Freelancers and contractors can deduct ordinary and necessary business expenses to reduce taxable income. Common deductions include home office (simplified method: $5/sq ft up to 300 sq ft), internet and phone (business-use percentage), software subscriptions, professional development, health insurance premiums (self-employed health insurance deduction), and retirement contributions (SEP-IRA up to 25% of net earnings, or Solo 401k).
Freelance Tax FAQ
Do I have to pay self-employment tax if I only earned a small amount?
If your net self-employment earnings are $400 or more in a year, you must file a Schedule SE and pay self-employment tax. Below $400, you still report the income but self-employment tax does not apply.
What is the difference between 1099-NEC and 1099-MISC?
1099-NEC reports nonemployee compensation (freelance work, contractor payments). 1099-MISC covers other types of income like rent, prizes, or attorney fees. If you did freelance work, you will typically receive a 1099-NEC.
Can I contribute to a retirement account as a freelancer?
Yes. A SEP-IRA allows contributions up to 25% of net self-employment income (max $69,000 in 2026). A Solo 401(k) allows both employee deferrals ($23,000 under 50, $30,500 if 50+) plus employer contributions up to 25% of net income. Both reduce your taxable income.
