FICA Tax Explained: What Self-Employed Workers Actually Pay
Yes, you pay FICA when you're self-employed — your return just calls it self-employment tax. Same Social Security, same Medicare, same rates. The difference is that an employee pays 7.65% and their employer matches it, while you pay both halves. Here's the bill on your own profit, then why it lands where it does.

Prefilled with $60,000 of net freelance profit and no W-2 job — the scenario worked through below. Enter your own net profit, and your W-2 wages if you have a day job, to see the Social Security and Medicare split.

How Self-Employment Tax Works
Step 1:Multiply net SE income by 92.35% to get taxable SE earnings. This adjustment accounts for the "employer" half of FICA.
Step 2: Apply 12.4% Social Security tax on earnings up to $168,600 (minus any W-2 wages already taxed).
Step 3: Apply 2.9% Medicare tax on all SE earnings (no cap). Add 0.9% Additional Medicare Tax on earnings over $200,000.
Step 4: Deduct half of the total SE tax from your adjusted gross income on Form 1040.
The short answer
- FICA is two taxes — Social Security (12.4% combined) and Medicare (2.9% combined). Together, 15.3%.
- W-2 workers split it — 7.65% withheld from your paycheck, 7.65% paid by the employer and never shown on your paystub.
- 1099 workers pay both halves — the full 15.3%, reported on Schedule SE as self-employment tax.
- Two adjustments soften it — only 92.35% of net profit is taxed, and half the SE tax is deductible against your income tax.
- Nothing is withheld — you owe it through quarterly estimated payments, not a paycheck deduction.
What FICA Actually Is
FICA stands for the Federal Insurance Contributions Act, the 1935 law that funds Social Security and Medicare out of payroll. It isn't a tax on your income in the way the federal income tax is — it buys you coverage. The Social Security portion credits an earnings record that determines your future retirement benefit; the Medicare portion buys hospital insurance eligibility at 65.
Technically, FICA applies to wages. When you work for yourself you have no wages, so Congress wrote a parallel statute — the Self-Employment Contributions Act, or SECA — that charges the same taxes on net earnings from self-employment. That is the tax your Schedule SE computes, and it is why the phrase "FICA" never appears on a freelancer's return even though the freelancer is unambiguously paying it.
This naming gap is the whole source of the confusion. People search for "do self-employed pay FICA" because they look at Form 1040, see no FICA line, and reasonably wonder if they escaped it. They did not. They pay more of it.
W-2 vs. 1099: Same Tax, Different Share
The rate never changes. What changes is how many halves of it you personally pay, and whether anyone withholds it for you.
| W-2 employee | 1099 / self-employed | |
|---|---|---|
| Called | FICA | Self-employment tax (SECA) |
| You pay | 7.65% | 15.3% |
| Employer pays | 7.65% | Nothing — there isn't one |
| Charged on | Gross wages | 92.35% of net profit, after expenses |
| Collected by | Paycheck withholding | You, via quarterly estimated payments |
| Reported on | Form W-2, boxes 4 and 6 | Schedule SE |
| Deductible? | No | Half, above the line |
Notice the row most people miss: your employer's 7.65% is real money paid on your behalf that never appears on your paystub. Economists generally treat it as compensation you would otherwise have received as wages — which means a W-2 employee arguably bears the full 15.3% too, just invisibly. The freelancer's burden isn't so much heavier as it is visible. That is cold comfort in April, when it's your money leaving your account. See the full 1099 vs W-2 comparison for what this does to an identical salary.
The Doubling Effect, Worked: $60,000 of Profit
Two people earn $60,000. One is an employee; one freelances and nets the same after expenses. Federal Social Security and Medicare only — no income tax in these columns.
W-2 employee
$9,180 reaches Social Security and Medicare — you only ever see half of it leave.
Self-employed
Half ($4,239) is an above-the-line deduction against income tax — but the full $8,478 is still owed.
The freelancer pays $3,888 more out of pocket than the employee — the employer's missing match. But notice it isn't a clean doubling: two employee shares would be $9,180, and the actual SE tax is $8,478, or $702 less.
That gap is exactly the 92.35% adjustment. Self-employment tax always equals 92.35% of what both FICA halves would have been, because the IRS shaves the base to approximate the deduction a real employer gets for its share of payroll tax. Then half of what's left — $4,239 here — comes off your adjusted gross income, which lowers your income tax (by however much your bracket says) without lowering the SE tax itself by a penny.
2026 FICA Rate Table
These rates are fixed in statute and have not changed for 2026. The self-employed column is simply the employee and employer columns added together.
| Tax | Employee | Employer | Self-employed | Applies to |
|---|---|---|---|---|
| Social Security (OASDI) | 6.2% | 6.2% | 12.4% | Earnings up to the annual wage cap |
| Medicare (HI) | 1.45% | 1.45% | 2.9% | All earnings — no cap |
| Additional Medicare | 0.9% | None | 0.9% | Earnings over $200,000 single / $250,000 joint |
| Combined base rate | 7.65% | 7.65% | 15.3% |
Three details the table can't hold. The Social Security wage capis the one figure here that moves — the SSA re-indexes it to national wage growth every autumn, so confirm the current year's number on ssa.gov before you file. The calculator above applies $168,600. Second, the Additional Medicare surtax has no employer match, so the self-employed rate is 0.9%, not double it — and its thresholds are never inflation-adjusted. Third, the self-employed column is charged on 92.35% of net profit, while the employee and employer columns are charged on 100% of gross wages, so the effective self-employed rate always lands a little under 15.3%.
How to Reduce FICA as a Freelancer
Self-employment tax is a flat rate on net profit, so there is no bracket to drop into and no credit to claim. Only three things move the number.
- Lower your net profit with real deductions. This is the main lever, and the most under-used. SE tax is charged on Schedule C net profit, so every business expense you legitimately claim — mileage, home office, software, supplies — cuts SE tax and income tax. That makes Schedule C deductions roughly 50% more valuable per dollar than deductions taken further down Form 1040.
- Consider an S-corp election at higher profit. An S-corp shareholder-employee takes a reasonable salary, which pays FICA in the ordinary way, and receives the remaining profit as a distribution that carries no SE tax. The salary has to be defensible — the IRS litigates unreasonably low ones — and you take on payroll filings and accounting costs. The break-even generally starts somewhere around $40,000-$50,000 of net profit; the LLC vs sole proprietorship guide walks through where.
- Let a W-2 job fill the Social Security cap. Not a strategy so much as a fact worth knowing: wages from a day job count toward the wage cap first, so once they exceed it, your side hustle owes only the 2.9% Medicare piece rather than the full 15.3%. Enter your W-2 wages in the calculator above to see it happen.
And the list of things that do not reduce self-employment tax, all of which are routinely assumed to:
- The standard deduction and itemized deductions. Income tax only.
- SEP IRA and Solo 401(k) contributions. The IRS treats these as personal retirement contributions, not business expenses — they never touch Schedule C.
- The self-employed health insurance deduction. Above-the-line on Form 1040, not on Schedule C.
- The QBI deduction. Reduces taxable income by up to 20%; reduces SE tax by nothing.
- The half-of-SE-tax deduction. It shrinks the income your income tax is computed on. The SE tax itself is unchanged.
Model what a given expense is worth across both taxes with the deduction estimator, or start from gross receipts in the Schedule C calculator.
Paying It
Nobody withholds self-employment tax for you, which is the second surprise after the rate. You owe it in four quarterly estimated payments once you expect to owe $1,000 or more for the year, and the underpayment penalty is computed quarter by quarter — so clearing the whole balance in April does not undo a skipped first installment.
One threshold worth committing to memory: once your net self-employment earnings reach $400for the year, you must file a return and pay SE tax on them, regardless of whether any client sent you a 1099 and regardless of how little you owe in income tax. If you also hold a W-2 job, the simplest fix of all is raising that job's withholding — withholding counts as paid evenly across the year no matter when it actually happened.
Educational only — not tax advice. The Social Security wage cap is re-indexed annually; confirm current figures on irs.gov or ssa.gov, or with a CPA, before filing.
Frequently Asked Questions
Do self-employed pay FICA?
Yes — under a different name. FICA is the payroll tax collected from employees and employers; the self-employed pay the identical Social Security and Medicare taxes through SECA, which appears on your return as self-employment tax on Schedule SE. The programs funded, the 12.4% Social Security rate, and the 2.9% Medicare rate are the same. The only real difference is who writes the check: an employee pays 7.65% and the employer matches it, while a sole proprietor pays both halves — 15.3% — because there is no employer in the relationship.
How do I reduce FICA as a freelancer?
Only three levers actually work. First, claim every legitimate Schedule C business expense — deductions there cut net profit, and self-employment tax is charged on net profit, so each dollar reduces both SE tax and income tax. Second, if your net profit is consistently high (generally $40,000-$50,000 and up), an S-corp election lets you pay yourself a reasonable salary that carries FICA while the remaining profit is distributed without SE tax. Third, W-2 wages from a day job fill the Social Security wage cap first, which shrinks the 12.4% portion owed on your side hustle. What does not reduce SE tax: the standard deduction, itemized deductions, SEP IRA and Solo 401(k) contributions, self-employed health insurance, and the QBI deduction. All of those lower income tax only.
Is self-employment tax the same as FICA?
Economically yes, legally no. FICA is levied under the Federal Insurance Contributions Act on wages; self-employment tax is levied under the Self-Employment Contributions Act (SECA) on net earnings from self-employment. Both fund Social Security and Medicare at the same combined rates and both build the same Social Security earnings record. The practical differences are that SE tax applies to 92.35% of net profit rather than 100% of gross wages, it is not withheld from anything so you must pay it through quarterly estimated payments, and half of it is deductible against your adjusted gross income.
Why do self-employed workers pay double FICA?
Because you are both the employer and the employee. An employer owes a matching payroll tax on every wage dollar it pays; when you work for yourself there is nobody to owe it but you, so both halves land on your Schedule SE. It is not quite a doubling, though. The IRS taxes only 92.35% of net profit, which roughly mimics the deduction a business gets for its share of payroll tax, and half of the SE tax you pay is an above-the-line deduction that reduces the income your federal income tax is calculated on. Between those two adjustments, self-employment tax comes out somewhat below twice an employee's withholding.
Do I pay FICA twice if I have a W-2 job and a side hustle?
No, but the two interact. Your W-2 wages count toward the annual Social Security wage cap first. Schedule SE then charges the 12.4% Social Security portion only on whatever room is left under that cap, so a high earner whose day job already filled it owes nothing further for Social Security on the side hustle. Medicare is different: the 2.9% has no cap and applies to all of your net self-employment earnings no matter how much you made at the W-2 job.
Can I get a FICA refund if too much was withheld?
Sometimes. If you worked for two or more employers during the year and their combined wages exceeded the Social Security wage cap, each one correctly withheld up to the cap and you overpaid in aggregate. You claim that excess Social Security tax as a refundable credit on Schedule 3 of Form 1040. If a single employer over-withheld, the IRS will not refund it on your return — you have to ask that employer to correct it. Medicare tax is never refundable this way because it has no cap, though the extra 0.9% surtax is reconciled on Form 8959 and can come back to you if your employer withheld it but your household income landed under the threshold.
