Understanding Self-Employment Tax
If you work as a freelancer, independent contractor, gig worker, or sole proprietor, you are responsible for paying self-employment (SE) tax in addition to federal income tax. SE tax covers Social Security and Medicare — the same payroll taxes that W-2 employees split with their employers. But when you are self-employed, you pay both halves yourself. For 2026 the combined SE tax rate is 15.3% (12.4% Social Security plus 2.9% Medicare), calculated on 92.35% of your net earnings.
How SE Tax is Calculated
The IRS first multiplies your net self-employment income by 92.35% to arrive at your SE tax base. This reduction accounts for the employer-equivalent portion of FICA. Social Security tax of 12.4% applies to the SE base up to the wage base cap of $184,500 for 2026 (minus any W-2 wages already subject to Social Security withholding). Medicare tax of 2.9% applies to the entire SE base with no cap. If your combined earned income exceeds $200,000 for single filers ($250,000 for married filing jointly), an Additional Medicare Tax of 0.9% applies on the excess. You can deduct half of your total SE tax from gross income, reducing your federal income tax. For a more detailed look at how your total refund might shape up, see our tax refund calculator.
The 1099-K Reporting Threshold
For tax year 2026, the 1099-K reporting threshold returns to $20,000 and 200 transactions. This means payment processors like PayPal, Venmo, Cash App, and Stripe will send a 1099-K to both you and the IRS when your gross payments exceed both limits. Keep in mind that you must report all self-employment income on your tax return regardless of whether you receive a 1099-K, 1099-NEC, or any other information return. Good record-keeping throughout the year is essential.
Reducing Your SE Tax Burden
There are several legal strategies to lower your self-employment tax. Contributing to a SEP-IRA or Solo 401(k) reduces your taxable income (though not the SE tax base itself). Electing S-corporation status allows you to pay yourself a reasonable salary and take additional profits as distributions, which are not subject to SE tax. You can also deduct legitimate business expenses — home office, mileage, equipment, software — to reduce net income before SE tax is calculated. And don't forget: half of your SE tax is always deductible from gross income. If you also earn tips, our tips tax deduction calculator can help you estimate additional savings under the OBBB Act.
Quarterly Estimated Payments
The IRS expects self-employed taxpayers who will owe $1,000 or more in taxes to make quarterly estimated payments using Form 1040-ES. The due dates are April 15, June 15, September 15, and January 15 of the following year. Missing these deadlines can trigger underpayment penalties. A good rule of thumb is to set aside 25-30% of your net self-employment income for taxes throughout the year.
