What this means

Self-employment tax is 15.3% of net earnings — but the IRS applies it to 92.35% of your net income (because you can deduct the employer half of the tax). So the effective SE tax rate on your gross net earnings is about 14.13%. On top of that, you pay regular federal and state income tax.

The good news: you can deduct half of your SE tax above-the-line, reducing your AGI before income tax is calculated. And contributions to a SEP-IRA (up to 25% of net earnings, max $69,000 in 2026) or Solo 401(k) come off your AGI too — the biggest tax lever available to self-employed people.

Most freelancers should set aside 25–30% of every payment for taxes. This calculator tells you your personal number based on your actual income and deductions.

CFO Tip
CFO
Set up a separate bank account just for taxes and transfer 28–30% of every payment the moment it hits. Never touch that account except to pay quarterly estimates. This one habit eliminates 90% of the tax-season panic that kills freelancers. It sounds obvious because it is — but almost nobody does it consistently.
Self-employment tax explained for 2026

Why 92.35%?

The IRS multiplies your net self-employment income by 92.35% before applying the 15.3% SE tax rate. This accounts for the fact that W-2 employees pay FICA on their gross wages, but their employer absorbs half the cost. The 92.35% factor roughly equalizes the treatment — you're effectively deducting the employer's 7.65% share before calculating the tax.

SEP-IRA vs Solo 401(k)

A SEP-IRA lets you contribute up to 25% of net self-employment income (after the SE tax deduction), with a max of $69,000 in 2026. It's simple to set up and contributions can be made up to your tax filing deadline. A Solo 401(k) has higher potential contributions for higher earners because it allows both employee and employer contributions — but requires more administration.

Additional Medicare Tax

Self-employed individuals with net earnings above $200,000 (single) or $250,000 (married jointly) pay an additional 0.9% Medicare surtax on earnings above those thresholds. This applies on top of the standard 15.3% SE tax and is not included in the employer match — it's entirely the employee/self-employed person's burden. High-earning freelancers should factor this in.

Deductible business expenses

The IRS allows deductions for ordinary and necessary business expenses: home office (actual expense or $5/sq ft up to 300 sq ft), vehicle (standard mileage is $0.70/mile in 2026 or actual expenses), equipment, software, professional development, professional services, and health insurance premiums. These deductions reduce your net earnings before SE tax is even calculated — making them doubly valuable.

Frequently asked questions
What is self-employment tax and who pays it?+
Self-employment tax is the 15.3% tax that covers Social Security (12.4%) and Medicare (2.9%) for people who work for themselves. W-2 employees split this with their employer, each paying 7.65%. Self-employed individuals pay both portions. It applies to anyone with net self-employment income of $400 or more in a year, regardless of age or whether you also have W-2 income.
Can I deduct half of my self-employment tax?+
Yes. The IRS allows you to deduct 50% of your self-employment tax from your gross income when calculating your income tax. This deduction is taken on Schedule 1 of your Form 1040. It doesn't reduce your SE tax liability, but it does reduce your taxable income for federal and state income tax purposes, partially offsetting the burden.
What is the self-employment tax rate above the Social Security wage base?+
Once your net self-employment income exceeds the 2026 Social Security wage base of $176,100, the 12.4% Social Security portion stops. You continue paying the 2.9% Medicare tax on all income above that threshold. Additionally, high earners pay an Additional Medicare Tax of 0.9% on income above $200,000 (single) or $250,000 (married filing jointly).
How can a SEP-IRA reduce self-employment tax?+
A SEP-IRA reduces your taxable income for federal and state income taxes, but it does not reduce your self-employment tax base — SE tax is calculated on net self-employment income before the SEP-IRA deduction. However, the income tax savings are substantial. Contributing $20,000 to a SEP-IRA in the 22% federal bracket saves $4,400 in federal income tax.
What forms do I need to file as self-employed?+
Self-employed individuals file Schedule C (profit or loss from business) and Schedule SE (self-employment tax) with their Form 1040. If you have net income from self-employment, Schedule SE is required. Quarterly estimated tax payments are made using Form 1040-ES. If you have a single-member LLC, you're treated as a sole proprietor for tax purposes and use the same forms.
