2025 FICA Rate: 7.65% for Employees, 15.3% for the Self-Employed
How Much FICA Tax Do You Actually Pay?
FICA taxes fund Social Security and Medicare. The rates themselves are fixed by law and rarely change — what changes every year is the Social Security wage base, the ceiling on earnings subject to the 6.2% Social Security tax. For 2025, that ceiling is $176,100, up from $168,600 in 2024.
| Worker Type | Social Security | Medicare | Total | Wage Base Applies? |
|---|---|---|---|---|
| Employee | 6.2% | 1.45% | 7.65% | Yes (SS only) |
| Employer | 6.2% | 1.45% | 7.65% | Yes (SS only) |
| Self-Employed | 12.4% | 2.9% | 15.3% | Yes (SS only) |
| High earners (>$200K single) | 6.2% | 2.35%* | 8.55%* | Yes (SS only) |
*An additional 0.9% Medicare surtax applies to wages above $200,000 (single) or $250,000 (married filing jointly). Employers withhold this on wages they pay above the threshold, but they do not match it.
Why does the wage base change every year but the rates never do? Congress sets the FICA tax rates in the Social Security Act and the Internal Revenue Code, so changing them requires new legislation. The wage base, on the other hand, is adjusted automatically each year by the Social Security Administration based on national average wage growth — no new law needed.
Social Security Wage Base: 2021–2025
The Social Security wage base has increased almost every year since it was introduced, tracking growth in average U.S. wages. Here is how it has moved over the last five years.
| Year | SS Wage Base | Change from Prior Year |
|---|---|---|
| 2021 | $142,800 | +$5,100 |
| 2022 | $147,000 | +$4,200 |
| 2023 | $160,200 | +$13,200 |
| 2024 | $168,600 | +$8,400 |
| 2025 | $176,100 | +$7,500 |
Worked Example: W-2 Employee Earning $200,000 in 2025
The employer matches $13,818. Social Security withholding stops once wages hit $176,100 for the year — this employee sees a noticeably larger paycheck for the rest of the year once they cross that threshold. The 0.9% Medicare surtax does not apply until wages exceed $200,000, so it kicks in on the very next dollar.
Self-Employment Tax vs. FICA in 2025
Freelancers, independent contractors, and sole proprietors do not have an employer to split FICA with, so they pay both halves themselves through self-employment (SE) tax — the full 15.3% on 92.35% of net earnings. The 92.35% adjustment roughly approximates the employer-side deduction that W-2 employees get for free.
The IRS lets self-employed taxpayers deduct half of their SE tax as an above-the-line adjustment on Schedule 1 of Form 1040. That deduction reduces adjusted gross income and does not require itemizing.
SE Tax Example: Freelancer with $85,000 Net Profit in 2025
Quarterly payments matter. FICA is withheld automatically from a paycheck, but self-employment tax is not. Most self-employed taxpayers need to make quarterly estimated payments to avoid an IRS underpayment penalty. Use the self-employment tax calculator to estimate what you owe for the year.
What Counts as FICA Wages?
FICA is calculated on gross wages before most deductions — but not all of them. Pre-tax deductions like traditional 401(k) contributions and health insurance premiums reduce your federal income tax withholding, but they generally do not reduce your FICA wages. Your Social Security and Medicare tax is still based on your full gross pay, with a few narrow exceptions.
On a typical pay stub, look for lines labeled "Social Security Tax," "OASDI," or "Medicare Tax." Together they should equal 7.65% of that pay period's gross wages, until your year-to-date wages cross the $176,100 Social Security ceiling, at which point only the 1.45% Medicare line continues.
Bonuses and overtime count too. FICA applies to nearly every form of taxable compensation, including bonuses, commissions, and overtime pay, not just base salary. If you got a bonus this year, see our 2025 bonus tax rate guide for how that income is withheld separately from your regular paycheck.
