What FICA Taxes Actually Pay For
FICA stands for the Federal Insurance Contributions Act, and it's the line on your pay stub that funds two programs: Social Security and Medicare. Unlike federal income tax, FICA is a flat percentage — everyone pays the same rate (up to a wage limit for Social Security), regardless of filing status or deductions.
The 2026 FICA Rates Breakdown
- Social Security: 6.2% on wages up to the annual wage base
- Medicare: 1.45% on all wages, no limit
- Additional Medicare: +0.9% on wages above $200,000 (single filer)
- Total standard rate: 7.65%

Social Security tax only applies up to a certain amount of income each year — this is called the wage base. For 2026, the Social Security wage base is $184,500. Once your year-to-date wages cross that line, Social Security withholding stops for the rest of the year. Medicare has no such cap — it applies to every dollar you earn.
How Self-Employed Workers Pay FICA
If you're a 1099 contractor, freelancer, or gig worker, there's no employer to split the cost with — so you pay both halves. This is called self-employment tax, and it adds up to 15.3% of your net self-employment earnings (12.4% Social Security + 2.9% Medicare).
The good news: you can deduct half of your self-employment tax when calculating your federal income tax, which softens the blow somewhat.
Example: FICA on a $60,000 Salary
- Social Security (6.2%): -$3,720
- Medicare (1.45%): -$870
- Total FICA: $4,590/year
Can You Reduce FICA Taxes?
Unlike federal income tax, FICA is calculated on your gross wages before most pre-tax deductions. Traditional 401(k) contributions, for example, reduce your federal taxable income but not your FICA wages. The main exceptions are certain cafeteria-plan benefits like health insurance premiums and FSA contributions, which can lower your FICA-taxable wages slightly. For a full example of FICA combined with federal and state tax in one paycheck, see our breakdown of a $75,000 salary in Texas.
Frequently Asked Questions
What does FICA stand for?
FICA stands for the Federal Insurance Contributions Act. It's the federal payroll tax that funds Social Security and Medicare, and it's separate from federal income tax.
Is FICA the same as federal income tax?
No. FICA is a flat 7.65% for most employees that funds Social Security and Medicare specifically. Federal income tax uses progressive brackets from 10% to 37% and funds general government spending — they're calculated and withheld separately.
Do I pay FICA on my 401(k) contributions?
Yes. Unlike federal income tax, FICA is calculated on your gross wages before most pre-tax deductions, including traditional 401(k) contributions. Only certain cafeteria-plan benefits like health insurance premiums can lower your FICA-taxable wages.
What happens once I earn more than the Social Security wage base?
Once your year-to-date wages cross the $184,500 wage base for 2026, Social Security withholding (6.2%) stops for the rest of the year. Medicare (1.45%) has no cap and continues on every dollar, plus an extra 0.9% above $200,000 for single filers.
How is FICA different for self-employed workers?
Self-employed workers don't have an employer to split FICA with, so they pay both halves — 12.4% for Social Security and 2.9% for Medicare, totaling 15.3% in self-employment tax. Half of this amount can be deducted when calculating federal income tax.
