Self-Employment Tax Calculator (2026)
Estimate your self-employment tax, federal income tax and quarterly payments.
| Social Security (12.4%) | $0 |
| Medicare (2.9%, +0.9% on high incomes) | $0 |
| Federal income tax on your freelance profit | $0 |
| State income tax (estimate) | $0 |
| Total estimated tax | $0 |
Estimate for tax year 2026 using IRS brackets, the standard deduction, the deduction for half of self-employment tax, the Social Security wage base ($184,500) and the QBI deduction (assumes a service business). It doesn’t include credits, itemized deductions or local taxes. For information only, not tax advice.
Employees never see this tax because their employer pays half of it and withholds the rest from each paycheck. When you work for yourself, you’re both the employee and the employer, so you pay both halves. That’s why your first tax bill as a freelancer often feels much bigger than you expected.
How to use the self-employment tax calculator
You only need four numbers:
| Field | What to enter |
|---|---|
| Net self-employment profit | Your freelance income minus business expenses for the year. It’s the figure on line 31 of Schedule C. Use your best projection if the year isn’t over. |
| Filing status | Single or married filing jointly. It changes your standard deduction and tax brackets. |
| Other W-2 wages | Any salary from a job, yours or your spouse’s. Leave it at 0 if you only freelance. |
| State income tax rate | Your state’s approximate rate. Use 0 if you live in a state with no income tax, like Texas or Florida. |
What the results mean:
- Self-employment tax is the Social Security and Medicare you pay as your own employer. This is the main number the calculator is built for.
- Federal income tax on your freelance profit is the extra income tax your freelance work adds. If you also have a job, it shows only the tax caused by your side income.
- Total estimated tax adds both, plus your state estimate.
- Quarterly payment is the total divided by four: roughly what to send the IRS and your state each quarter.
- Set aside from each payment is the share of every client payment to move into savings, rounded up for a small cushion.
The calculator runs on the 2026 figures: the Social Security wage base of $184,500, the standard deduction ($16,100 single, $32,200 married filing jointly) and the current tax brackets.
How to calculate self-employment tax by hand
If you’d rather see the math, here’s exactly what the calculator does. It follows the same steps as IRS Schedule SE.
- Start with your net profit. Take your gross freelance income and subtract your business expenses.
- Multiply by 92.35%. This adjustment mirrors the fact that employees don’t pay tax on their employer’s half of the tax. The result is your net earnings from self-employment. If it’s under $400, you owe no self-employment tax.
- Social Security: multiply by 12.4%, but only on the first $184,500 of earnings in 2026. If you also have a W-2 job, your salary uses up part of that limit first.
- Medicare: multiply by 2.9%, with no limit. Above $200,000 of earnings ($250,000 if married filing jointly), an extra 0.9% applies.
- Add them together. That’s your self-employment tax.
Worked example: $60,000 of net profit, single, no other job
| Step | Calculation | Result |
|---|---|---|
| Net earnings | $60,000 × 92.35% | $55,410 |
| Social Security | $55,410 × 12.4% | $6,871 |
| Medicare | $55,410 × 2.9% | $1,607 |
| Self-employment tax | $6,871 + $1,607 | $8,478 |
That’s 14.1% of profit. You can then deduct half of it, $4,239, from your income before calculating income tax, which lowers your income tax bill a little. Want the full walkthrough? Read self-employment tax explained.
Why your total tax is higher than 15.3%
Self-employment tax is only part of the bill. You also owe regular federal income tax on the same profit, and possibly state tax. The calculator estimates these too, because you’ll need to pay all of them.
The good news is that your income tax is charged on much less than your full profit. In 2026, three deductions shrink it:
- Half of your self-employment tax. In the example above, $4,239.
- The standard deduction: $16,100 if single, $32,200 if married filing jointly.
- The Qualified Business Income (QBI) deduction: up to 20% of your business income. For service businesses, it starts to phase out once taxable income passes $201,750 (single) or $403,500 (married filing jointly). Learn how the QBI deduction works for freelancers.
For our single freelancer with $60,000 of profit, that brings taxable income down to about $31,700, and federal income tax to $3,559. Add the $8,478 of self-employment tax and the federal total is $12,037, about 20% of profit.
This is why self-employment tax is the bigger bill for most freelancers: it’s charged on almost all of your profit, while income tax only hits what’s left after deductions.
How to lower your self-employment tax (legally)
Self-employment tax is charged on profit, so there are really only two levers: lower your profit with legitimate expenses, or change how your business is taxed.
1. Claim every business expense you’re entitled to. Each $1,000 of deductible expenses saves about $141 in self-employment tax, plus income tax. Common ones freelancers miss: the home office, a share of your phone and internet, software subscriptions, equipment and business mileage. See the full list of freelancer tax deductions.
2. Consider an S corp once your profit is high enough. As an S corp owner, you pay yourself a reasonable salary (subject to payroll taxes) and take the rest as distributions, which aren’t subject to self-employment tax. It adds payroll, accounting and state costs, so it usually only pays off at higher profits. Find your break-even point in our guide on when to become an S corp.
What doesn’t lower it: a few popular tax moves reduce your income tax but not your self-employment tax. Contributions to a SEP IRA or Solo 401(k), the self-employed health insurance deduction and the QBI deduction all fall into this group. They’re still well worth using, but they won’t change the self-employment tax number in the calculator.
What to do with your self-employment tax calculator results
An estimate only helps if you act on it. Here’s how to turn the numbers into a plan:
- Save the “set aside” percentage from every payment. Move it to a separate savings account the day the money arrives. Our guide on how much to set aside for taxes explains the system.
- Pay quarterly. If you expect to owe $1,000 or more, the IRS expects quarterly estimated taxes during the year. For the 2026 tax year they’re due April 15, June 15 and September 15, 2026, and January 15, 2027 (see all estimated tax due dates). You can pay estimated taxes online with IRS Direct Pay, and check your state’s own schedule.
- Protect yourself with the safe harbor. Paying 100% of last year’s total tax (110% if your adjusted gross income was over $150,000) during the year avoids underpayment penalties, even if this year turns out bigger. See the safe harbor rule.
- Rerun the self-employment tax calculator every quarter. Freelance income rarely stays flat. Update your projected profit before each payment so you don’t overpay early or face a surprise in April.
The calculator’s quarterly figure includes your state estimate. Send the federal part to the IRS and the state part to your state’s tax agency: they’re separate payments.
Frequently asked questions
What is the self-employment tax rate for 2026?
15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies to 92.35% of your net profit. Social Security stops at $184,500 of earnings in 2026, and an extra 0.9% Medicare tax applies above $200,000 ($250,000 married filing jointly).
Do I pay self-employment tax if I also have a full-time job?
Yes, on your freelance profit. Your salary doesn’t exempt you. The only overlap is the Social Security cap: if your salary and freelance earnings together pass $184,500, you stop paying the 12.4% part above that. Enter your salary in the calculator to account for it.
Is there a minimum income before self-employment tax applies?
Yes. You owe it only if your net earnings from self-employment (net profit × 92.35%) are $400 or more for the year.
Is self-employment tax deductible?
Half of it is. You deduct 50% of your self-employment tax from your income on your Form 1040, which lowers your income tax. It doesn’t lower the self-employment tax itself.
How accurate is this self-employment tax calculator?
It uses the official 2026 IRS figures and gives a solid estimate for most sole proprietors and single-member LLCs. It doesn’t include tax credits, itemized deductions, capital gains or local taxes, and it assumes a service business for the QBI deduction. Use it for planning, and confirm your final numbers with tax software or a tax professional.
