Self-employment tax is the single biggest surprise for new freelancers and gig workers. When you’re an employee, your employer pays half of your Social Security and Medicare taxes. When you’re self-employed, you pay both halves — and that adds up fast.

This guide breaks down exactly how the 2026 self-employment tax rate works, how to calculate what you owe, and the deductions that soften the blow.

The 15.3% Rate, Explained

The self-employment (SE) tax rate for 2026 is 15.3% of your net self-employment earnings. It’s made up of two components:

• Social Security tax: 12.4% — This applies to your first $176,100 of net self-employment earnings in 2026 (the Social Security wage base). Earnings above this cap are not subject to the 12.4%.
• Medicare tax: 2.9% — This applies to all net self-employment earnings with no cap.

If you’re a W-2 employee, you only see 7.65% come out of your paycheck because your employer pays the other 7.65%. As a self-employed worker, you’re both the employee and the employer, so you pay the full 15.3%.

The 92.35% Rule

Here’s some good news: you don’t pay the 15.3% on your total net profit. The IRS lets you reduce your net self-employment earnings by 7.65% before calculating SE tax. In practice, you multiply your Schedule C net profit by 0.9235 (92.35%) to get your “taxable self-employment earnings.”

This adjustment accounts for the fact that employees don’t pay FICA tax on the employer’s share of FICA. It’s a small but meaningful reduction.

Example: If your Schedule C net profit is $60,000, your taxable SE earnings are $60,000 × 0.9235 = $55,410. Your SE tax is $55,410 × 0.153 = $8,478.

SE Tax at Three Income Levels

Let’s run the numbers for three common income levels to show what self-employment tax actually looks like in practice.

Net Profit	Taxable SE Earnings	SE Tax Owed	Effective Rate
$40,000	$36,940	$5,652	14.13%
$60,000	$55,410	$8,478	14.13%
$100,000	$92,350	$14,130	14.13%

Notice the effective rate is about 14.13% rather than the headline 15.3%. That’s the 92.35% multiplier doing its work. For a gig worker earning $60,000, the SE tax alone is $8,478 — and that’s before income tax.

Additional Medicare Tax for High Earners

If your net self-employment earnings exceed $200,000 (single) or $250,000 (married filing jointly), you’ll owe an additional 0.9% Medicare surtax on the amount above the threshold. This is sometimes called the Additional Medicare Tax, and it was introduced by the Affordable Care Act.

For example, a freelancer with $250,000 in net SE earnings (filing single) would owe the standard 2.9% Medicare tax on all earnings, plus an additional 0.9% on the $50,000 above the $200,000 threshold — an extra $450.

The Social Security Wage Base for 2026

The Social Security portion of SE tax (12.4%) only applies to your first $176,100 in net self-employment earnings for 2026. This cap is adjusted annually for inflation. Once your taxable SE earnings exceed this amount, you stop paying the 12.4% Social Security tax on additional earnings — but you still owe the 2.9% Medicare tax (and potentially the 0.9% surtax) on everything above it.

For most gig workers and freelancers, this cap won’t come into play. But if you have a particularly strong year, or if you also earn W-2 wages, the combined total across all income sources determines when you hit the cap.

The Deduction That Takes the Edge Off

The IRS allows self-employed individuals to deduct 50% of their SE tax as an above-the-line deduction on Form 1040. This doesn’t reduce your SE tax itself, but it does lower your adjusted gross income (AGI), which reduces your income tax.

Using the $60,000 example above: SE tax is $8,478, so you’d deduct $4,239 from your AGI. If you’re in the 22% income tax bracket, that saves you about $933 in income tax.

SE Tax vs. Income Tax: They’re Separate

A common point of confusion: self-employment tax and income tax are two different things. You owe both.

• Self-employment tax (15.3%) is calculated on Schedule SE and covers your Social Security and Medicare contributions.
• Federal income tax (10%–37%) is calculated on your total taxable income after deductions and credits, using the standard tax brackets.

So a gig worker earning $60,000 in net profit doesn’t just owe $8,478 in SE tax. They also owe federal income tax on their taxable income (after the standard deduction and the 50% SE tax deduction). The total combined tax bill is typically 25%–30% of net self-employment income for most filers.

Quarterly Estimated Payments

Because no employer is withholding taxes for you, the IRS expects you to pay estimated taxes four times per year. If you owe more than $1,000 at filing time, you’ll face underpayment penalties. Divide your expected annual tax (SE tax + income tax) by four and pay each quarter using IRS Form 1040-ES.

The Bottom Line

The 15.3% self-employment tax rate is one of the largest expenses for freelancers and gig workers — but understanding how it works is the first step toward managing it. The 92.35% net earnings calculation, the 50% above-the-line deduction, and maximizing your business expenses all work together to bring your effective rate down from the headline 15.3% to something more manageable.

The most important thing you can do is track your expenses and deductions throughout the year. Every dollar of deductions saves you roughly 15 cents in SE tax on top of whatever you save in income tax.
