FICA Tax Explained: Social Security and Medicare Tax Rates (2025–2026)
Understand how FICA taxes work — Social Security and Medicare rates, wage base limits, Additional Medicare Tax, and how self-employment tax connects.
FICA tax is the 7.65% deducted from every paycheck for Social Security (6.2%) and Medicare (1.45%) — your employer pays a matching 7.65%, bringing the total to 15.3%. For 2025 Social Security tax applies on wages up to $176,100; for 2026 the cap rises to $183,000 (est.). This guide breaks down FICA rates, thresholds, and how self-employment tax connects.
Key Takeaways
- FICA = 6.2% Social Security + 1.45% Medicare from your paycheck (employer pays the same amount).
- Social Security tax stops at the wage base: $176,100 (2025) / $183,000 (2026 est.).
- Medicare tax has no cap — and high earners pay an extra 0.9% on top.
- Self-employed workers pay both halves: 15.3% total.
- You cannot avoid FICA on wages, but understanding the caps helps you plan.
FICA Tax Rates at a Glance
| Component | Employee Share | Employer Share | Total |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% |
| Medicare | 1.45% | 1.45% | 2.9% |
| Total FICA | 7.65% | 7.65% | 15.3% |
Your employer withholds 7.65% from every paycheck and contributes a matching 7.65% on top. You never see the employer share on your pay stub, but it is a real cost of your employment.
Social Security Tax and the Wage Base
Social Security tax applies only up to the wage base limit. Once your earnings hit the cap, you stop paying the 6.2% for the rest of the year.
| Year | Wage Base | Max Employee SS Tax |
|---|---|---|
| 2025 | $176,100 | $10,918 |
| 2026 (est.) | $183,000 | $11,346 |
If you earn $176,100 or more in 2025, you will pay exactly $10,918 in Social Security tax — no more, regardless of whether you earn $200,000 or $2 million. This cap resets each January.
Multiple employers? If you work two jobs, each employer withholds Social Security tax independently. If your combined wages exceed the wage base, the excess withholding is refunded when you file your return (as a credit on your 1040).
Medicare Tax: No Cap
Unlike Social Security, Medicare tax has no wage base limit. Every dollar of wages is subject to the 1.45% Medicare tax. There is no ceiling and no refund for over-withholding.
Additional Medicare Tax (0.9%)
High earners pay an extra 0.9% Medicare surtax on wages above these thresholds:
| Filing Status | Threshold |
|---|---|
| Single | $200,000 |
| Married Filing Jointly | $250,000 |
| Married Filing Separately | $125,000 |
Only the employee pays the Additional Medicare Tax — there is no employer match. Your employer begins withholding the 0.9% once your wages from that job exceed $200,000 (regardless of filing status). If the withholding does not match your actual liability based on filing status, you reconcile on Form 8959 when you file.

Worked Example: Employee Earning $250,000
Here is how FICA breaks down for a Single filer earning $250,000 in 2025:
| Tax | Calculation | Amount |
|---|---|---|
| Social Security (6.2%) | $176,100 x 6.2% | $10,918 |
| Medicare (1.45%) | $250,000 x 1.45% | $3,625 |
| Additional Medicare (0.9%) | ($250,000 - $200,000) x 0.9% | $450 |
| Total Employee FICA | $14,993 |
That is $14,993 in FICA taxes alone — before any federal or state income tax. The employer pays an additional $14,543 ($10,918 + $3,625) on top of the gross salary.
The Self-Employment Tax Connection
If you are self-employed, freelance, or run a business as a sole proprietor, you do not have an employer to split FICA with. Instead, you pay self-employment tax — the full 15.3% on your net self-employment earnings.
The good news: you can deduct the employer-equivalent half (7.65%) as an above-the-line deduction when calculating your adjusted gross income (AGI). This reduces your income tax, though not the self-employment tax itself.
Many self-employed business owners eventually elect S-Corp status to split income between a reasonable salary (subject to FICA) and distributions (not subject to FICA). For more on the employer side of payroll taxes, see our payroll tax guide.
FICA vs Income Tax
FICA and income tax are separate systems:
| Feature | FICA Tax | Income Tax |
|---|---|---|
| Rate | Flat 7.65% (employee) | Progressive 10%–37% |
| Deductions reduce it? | No | Yes |
| Standard deduction applies? | No | Yes |
| Applies to first dollar | Yes | No (deductions reduce taxable income) |
| Wage base cap | SS portion only ($176,100 / $183,000) | None |
This is why lower- and middle-income earners often pay more in FICA than in federal income tax. To see how your total tax burden compares, check your effective tax rate. FICA hits every dollar from dollar one, with no standard deduction or personal exemption to reduce it.
How FICA Appears on Your Pay Stub and Tax Forms
On your pay stub, you will see FICA listed as “Social Security” and “Medicare” withholding (sometimes labeled “OASDI” for Social Security). At year-end, your W-2 reports:
- Box 4 — Social Security tax withheld
- Box 6 — Medicare tax withheld
Your employer files Form 941 quarterly to report and remit the combined employee + employer FICA to the IRS. If you are self-employed, you calculate self-employment tax on Schedule SE attached to your 1040.
