FICA is the payroll tax that funds Social Security and Medicare

FICA stands for the Federal Insurance Contributions Act. It is a payroll tax taken directly from your paycheck. The money funds two programs: Social Security (which pays retirement, disability, and survivor benefits) and Medicare (which pays for health insurance for people 65 and older, and some younger people with disabilities).

FICA appears on your pay stub as two separate line items. One goes to Social Security; the other goes to Medicare. Your employer also pays an equal amount on your behalf, though you do not see that deducted from your check. Self-employed people pay both the employee and employer portions themselves.

Unlike income tax, which varies based on your tax bracket and deductions, FICA is a flat percentage of your gross wages up to a certain limit each year. That limit changes annually and applies only to Social Security; Medicare has no wage cap.

Key Takeaways

  • FICA taxes fund Social Security retirement benefits and Medicare health insurance, with separate rates for each program.
  • In 2024, the Social Security rate is 6.2% of wages up to $168,600, and the Medicare rate is 1.45% of all wages with no cap.
  • Your employer pays an equal amount that does not appear on your paycheck, but self-employed people pay both portions themselves.
  • FICA is withheld automatically and you cannot opt out, even if you do not plan to use Social Security or Medicare later.
  • The amount you pay now determines your future Social Security benefit amount, which is based on your 35 highest-earning years.

How much FICA comes out of your paycheck

The Social Security portion is 6.2% of your wages, but only up to an annual wage cap. For 2024, that cap is $168,600. Once you earn that much in a calendar year, no more Social Security tax is withheld from your remaining paychecks that year. The Medicare portion is 1.45% of all your wages with no upper limit.

If you earn $60,000 a year, you pay $3,720 in Social Security tax (6.2% × $60,000) and $870 in Medicare tax (1.45% × $60,000), for a total FICA of $4,590. Your employer pays the same amount. If you earn $200,000, you pay $10,452.40 in Social Security tax (capped at $168,600) and $2,900 in Medicare tax, for a total of $13,352.40.

The wage cap and tax rates change each year. The Social Security Administration publishes the new cap in October for the following year. You can find the current rates on your pay stub or on the Social Security website.

Additional Medicare tax for higher earners

If you earn above a certain threshold, you pay an extra 0.9% Medicare tax on the amount over that threshold. For 2024, the threshold is $200,000 for single filers and $250,000 for married couples filing jointly. This additional tax has no wage cap and continues for the rest of the year.

Unlike the standard Medicare tax, your employer does not pay a matching portion of this additional tax. You bear the full cost. If you are self-employed, you pay both the employee and employer portions of all Medicare taxes, including the additional 0.9%.

What happens to FICA money after it is withheld

FICA taxes go into two separate trust funds managed by the Social Security Administration and the Centers for Medicare & Medicaid Services. The Social Security trust fund pays current retirees, disabled workers, and survivors of deceased workers. The Medicare trust fund pays for hospital insurance (Part A) and is supplemented by general tax revenue for other Medicare parts.

The system is pay-as-you-go: current workers' FICA taxes pay current beneficiaries. You are not building a personal account that sits in your name. Instead, you earn a record of contributions that determines your future benefit amount when you reach retirement age or become disabled.

Your Social Security benefit is calculated based on your 35 highest-earning years. The more you earn (up to the wage cap) and the longer you work, the higher your eventual benefit. If you have fewer than 35 years of earnings, zeros are counted for the missing years, which lowers your benefit.

Why FICA is withheld even if you will not use these programs

FICA is mandatory for all employees and self-employed people with net earnings of $400 or more per year. There is no religious exemption, no opt-out option, and no way to redirect your FICA taxes to a private account instead. You pay regardless of whether you plan to collect Social Security or enroll in Medicare.

Some people argue this is unfair if they will not live long enough to recoup what they paid, or if they earn enough to fund their own retirement. However, Social Security and Medicare are insurance programs, not savings accounts. Your FICA taxes also fund disability benefits and survivor benefits for your family if you die, even if you never reach retirement age.

How FICA affects your tax return

FICA taxes withheld from your paycheck appear on your W-2 form in boxes 4 (Social Security tax withheld) and 6 (Medicare tax withheld). You cannot deduct FICA from your taxable income on your tax return. It is a separate tax from federal income tax.

If you are self-employed, you report FICA taxes (called self-employment tax) on Schedule SE of your tax return. You can deduct half of your self-employment tax as an above-the-line deduction on Form 1040, which slightly reduces your taxable income. This deduction recognizes that self-employed people pay both the employee and employer portions.

If you had too much FICA withheld during the year — for example, because you worked multiple jobs and hit the Social Security wage cap more than once — you can claim a refund on your tax return. This is one of the few situations where FICA creates a tax benefit.

Frequently Asked Questions

Can I get my FICA taxes back if I leave the country?

No. FICA taxes are not refundable based on immigration status or departure from the United States. If you are not a U.S. citizen and you worked here, those taxes remain in the Social Security and Medicare trust funds. You may be able to collect Social Security benefits later if you meet the requirements, depending on your country of citizenship and any totalization agreements between the U.S. and your home country.

What if I paid FICA taxes but never worked long enough to get Social Security?

You need 40 work credits (roughly 10 years of earnings) to may have access to for Social Security retirement benefits. If you do not reach 40 credits, you will not receive a retirement benefit, and your FICA taxes are not refunded. However, your family members may still be able to collect survivor benefits if you die, and you may may have access to for disability benefits if you become unable to work.

Do I pay FICA taxes on tips?

Yes. Tips are considered wages for FICA purposes. Your employer should withhold FICA taxes on tips you report to them. If you receive cash tips you do not report, you are still legally required to pay FICA taxes on them when you file your tax return, though this is often not enforced for small amounts.

Why is my FICA tax the same every paycheck even though my income varies?

FICA is calculated as a percentage of each paycheck, so it changes with your pay. If your paychecks are the same amount, your FICA will be the same. If your pay varies (hourly work, commission, bonuses), your FICA will vary too. Once you hit the Social Security wage cap for the year, Social Security tax stops being withheld for the rest of that calendar year.
