FICA tax is the money taken from your paycheck for Social Security and Medicare

FICA stands for the Federal Insurance Contributions Act. It is a federal payroll tax that funds two programs: Social Security and Medicare. When you see a deduction on your pay stub labeled "FICA," "Social Security," or "Medicare," that money is going to one of these two programs.

FICA has two parts. The Social Security portion funds retirement, disability, and survivor benefits. The Medicare portion funds hospital insurance and medical coverage for people 65 and older, and for some younger people with disabilities or end-stage renal disease.

Most workers pay FICA tax automatically through payroll deduction. Your employer withholds the money and sends it to the Internal Revenue Service (IRS). If you are self-employed, you pay FICA tax yourself when you file your annual tax return, though the calculation is slightly different.

Key Takeaways

  • FICA tax is split between Social Security (6.2% of your wages) and Medicare (1.45% of your wages), with your employer paying an equal amount on your behalf.
  • Social Security tax stops once you reach the annual wage cap, which changes each year, but Medicare tax continues on all wages with no cap.
  • Self-employed workers pay both the employee and employer portions of FICA, totaling 15.3%, though they can deduct half of it on their tax return.
  • The money you pay into FICA now does not sit in an account with your name on it; it funds current beneficiaries, and your future benefits depend on your work history and when you claim.

How much FICA tax comes out of your paycheck

As an employee, you pay 7.65% of your gross wages in FICA tax. This breaks down as 6.2% for Social Security and 1.45% for Medicare. Your employer pays an additional 7.65% on your behalf, though you do not see this amount on your pay stub.

The Social Security portion has a wage cap. In 2024, you only pay Social Security tax on the first $168,600 of your annual wages. Once you earn more than that in a single year, Social Security tax stops being withheld from your paycheck. Medicare tax has no wage cap, so it continues on all your earnings no matter how much you make.

For example, if you earn $60,000 per year, you pay $3,720 in Social Security tax (6.2% of $60,000) and $870 in Medicare tax (1.45% of $60,000), totaling $4,590 in FICA tax. 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 (1.45% of $200,000), totaling $13,352.40.

FICA tax for self-employed workers

If you are self-employed, you pay both the employee and employer portions of FICA tax yourself. This is called self-employment tax, and it totals 15.3% of your net self-employment income (12.4% for Social Security and 2.9% for Medicare).

You calculate self-employment tax on Schedule SE (Form 1040), which you file with your annual tax return. The Social Security portion still has the annual wage cap—in 2024, you pay self-employment tax on the first $168,600 of net self-employment income. The Medicare portion continues on all net self-employment income with no cap.

Self-employed workers can deduct half of their self-employment tax when calculating their adjusted gross income (AGI) on their tax return. This deduction reduces the amount of income subject to federal income tax, though it does not reduce the FICA tax itself.

What happens to the money you pay in FICA tax

FICA tax does not go into a personal account with your name on it. Instead, the money collected from all workers funds current beneficiaries—people already receiving Social Security or Medicare. This is called a pay-as-you-go system.

Social Security tax revenue pays for retirement benefits, survivor benefits (paid to family members of deceased workers), and disability benefits. Medicare tax revenue pays for hospital insurance (Part A) and is used to help fund medical insurance (Part B) and prescription drug coverage (Part D).

Your future Social Security and Medicare benefits are based on your work history and the taxes you paid over your lifetime, not on the specific dollars you contributed. The amount you receive depends on how much you earned, how long you worked, and when you claim your benefits.

The difference between FICA tax and federal income tax

FICA tax and federal income tax are two separate deductions from your paycheck. Federal income tax funds general government operations and is based on your tax bracket, filing status, and withholdings. FICA tax is a fixed percentage that funds only Social Security and Medicare.

Federal income tax is withheld based on the W-4 form you complete with your employer. You can adjust your withholding if you want more or less money taken out. FICA tax, by contrast, is automatic and non-adjustable—the rate is set by law and applies to nearly all workers.

On your pay stub, you will see these as separate line items. A typical stub shows federal income tax withheld, Social Security tax withheld, Medicare tax withheld, and possibly state and local taxes as well.

Who pays FICA tax and who does not

Most workers in the United States pay FICA tax. This includes employees, self-employed workers, and certain government employees. However, some groups are exempt or have different rules.

Certain religious groups that object to insurance on religious grounds may request an exemption from self-employment tax. Some federal employees hired before 1984 pay into a different retirement system (the Civil Service Retirement System) instead of Social Security, though they still pay Medicare tax. State and local government employees sometimes have their own pension systems, though most now pay Social Security and Medicare tax as well.

Nonresident aliens on certain visas, some students on F-1 or J-1 visas, and employees of certain foreign governments may be exempt from FICA tax. The rules vary depending on visa status and the type of work.

How FICA tax connects to your future benefits

The FICA tax you pay now builds your record of earnings with Social Security. Social Security uses your 35 highest-earning years to calculate your benefit amount. If you have fewer than 35 years of earnings, zeros are counted for the missing years, which lowers your benefit.

To receive Social Security retirement benefits, you must have earned at least 40 credits. You earn one credit for each $1,730 of wages in 2024 (the amount changes annually). Most people earn four credits per year, so 40 credits typically takes 10 years of work.

Medicare may be able to access is also tied to FICA tax contributions. You become may be able to access for Medicare at age 65 if you have paid Medicare tax for at least 10 years (40 quarters). Some younger people with disabilities or end-stage renal disease can also receive Medicare after paying into the system for a shorter time.

Frequently Asked Questions

Why do I pay FICA tax if I might not receive benefits?

Can I opt out of paying FICA tax?

No. FICA tax is mandatory for nearly all workers in the United States. The only exceptions are specific religious groups with approved exemptions, certain nonresident aliens, and some government employees with alternative retirement systems. Most workers cannot choose to stop paying FICA tax.

What is the wage cap for FICA tax in my year?

The Social Security wage cap changes each year based on average wage growth. In 2024, the cap is $168,600. You can find the current year's cap on the Social Security Administration website. Medicare tax has no wage cap and applies to all earnings.

Do I get a refund if I overpay FICA tax?

If you work for multiple employers in the same year and overpay Social Security tax, you can claim a refund on your tax return. This happens because each employer withholds Social Security tax up to the wage cap without knowing about your other jobs. Medicare tax overpayment is not refundable.
