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

FICA stands for Federal Insurance Contributions Act. It is the law that requires your employer to take money from your paycheck and send it to the federal government. That money funds two programs: Social Security (retirement, disability, and survivor benefits) and Medicare (health insurance for people 65 and older, and some younger people with disabilities).

When you look at your pay stub, you will see a line that says "FICA" or breaks it into two parts: "Social Security" and "Medicare." The amount taken depends on how much you earn. Self-employed people pay FICA too, but they pay both the employee and employer share themselves.

FICA is separate from federal income tax. Income tax goes to the general Treasury and funds government operations. FICA goes directly into two dedicated trust funds that pay out benefits to current retirees, disabled workers, and Medicare recipients.

Key Takeaways

  • FICA takes 6.2% of your wages for Social Security and 1.45% for Medicare, up to an annual earnings cap for Social Security only.
  • Your employer matches the amount you pay, so the total FICA contribution is double what appears on your pay stub.
  • FICA is mandatory for almost all workers, including teenagers and part-time employees, with only a few exceptions.
  • The money you pay into FICA now funds current beneficiaries, not a personal account held in your name.

How much FICA comes out of your paycheck

The Social Security portion of FICA is 6.2% of your gross wages. The Medicare portion is 1.45% of your gross wages. Together, that is 7.65% of what you earn before taxes and deductions.

Social Security has a wage cap, which means once you earn a certain amount in a year, no more Social Security tax is taken from your paycheck. The cap changes each year. Medicare has no cap — you pay 1.45% on all your earnings, no matter how much you make. High earners pay an additional 0.9% Medicare tax on income above a threshold set by the IRS.

Your employer pays an equal amount on your behalf. So if you earn $1,000 and $76.50 comes out for FICA, your employer also sends $76.50 to the government. You do not see that employer contribution on your pay stub, but it counts toward your Social Security record.

Who has to pay FICA

Almost all workers in the United States pay FICA. This includes employees, part-time workers, teenagers, and immigrants with work authorization. You start paying FICA as soon as you earn wages, even if you are 16 years old.

A few groups are exempt. Railroad workers pay into a separate system called the Railroad Retirement Tax Act instead of FICA. Some government employees hired before certain dates may not pay FICA. Religious groups that have filed for exemption do not pay FICA. If you are unsure whether you are exempt, ask your employer or check your pay stub.

What FICA money actually funds

The 6.2% Social Security portion funds retirement benefits, disability benefits, and survivor benefits. When you turn 62 or older, you can receive a monthly check based on your earnings record. If you become disabled before retirement age, you may receive disability benefits. If you die, your spouse or children may receive survivor benefits.

The 1.45% Medicare portion funds hospital insurance (Part A), which covers inpatient hospital stays, skilled nursing facilities, and hospice care. It does not fund Medicare Part B (doctor visits) or Part D (prescription drugs), which are funded differently and have separate premiums.

The money you pay in does not sit in an account with your name on it. Instead, current FICA revenue pays current beneficiaries. Your future benefits will be paid by future workers' FICA contributions. This is called a pay-as-you-go system.

How FICA affects your Social Security record

Every dollar you pay into Social Security through FICA is recorded under your Social Security number. The Social Security Administration tracks your earnings year by year. When you turn 62, your benefit amount is calculated based on your 35 highest-earning years.

If you do not work long enough or earn enough, you may not be may have access to to your own Social Security benefit. You need 40 credits to receive retirement benefits. You earn one credit for each $1,640 you earn (this amount changes yearly), up to four credits per year. So you can earn 40 credits in as little as 10 years of work.

You can check your earnings record and see an estimate of your future benefits by creating an account on the Social Security Administration website. This shows you exactly how much FICA you have paid and what your projected benefit might be.

FICA for self-employed people

If you are self-employed, you pay FICA through the Self-Employment Tax. You pay both the employee share (6.2% for Social Security and 1.45% for Medicare) and the employer share (another 6.2% and 1.45%). That means self-employed people pay 15.3% total, though you can deduct half of it on your tax return.

Self-employed people report their net profit on Schedule C of their tax return and calculate Self-Employment Tax on Schedule SE. You pay this tax when you file your annual return, usually by April 15, or you can make quarterly estimated tax payments throughout the year.

FICA versus income tax

FICA and federal income tax are two separate deductions on your pay stub. FICA is a fixed percentage that goes to Social Security and Medicare. Income tax is based on your tax bracket and the number of dependents you claim on your W-4 form.

Income tax funds general government operations like defense, infrastructure, and federal agencies. FICA funds only Social Security and Medicare. You cannot opt out of FICA, but you can adjust your income tax withholding by changing your W-4 if you are having too much or too little taken out.

Some people confuse the two because both appear on the same pay stub. A straightforward way to remember: FICA is for retirement and health insurance. Income tax is for everything else the government does.

Frequently Asked Questions

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

No. FICA contributions are not refundable. However, if you are not a U.S. citizen and you leave the country, you may still be may have access to to Social Security benefits if you worked long enough. Some countries have agreements with the United States that allow workers to combine credits from both countries.

What happens to FICA if I die before retirement?

Your family may receive survivor benefits. Your spouse, children under 19 (or 23 if in school), and dependent parents may each receive a monthly benefit based on your earnings record. The total amount paid to your family is limited, but it can be substantial. Your family should contact the Social Security Administration to report your death.

Does FICA explore to tips?

Yes. Tips are considered wages and are subject to FICA. Your employer should withhold FICA on tips you report. If you do not report tips to your employer, you still owe FICA on them when you file your tax return. Cash tips that go unreported do not build your Social Security record.

Why is there a Social Security wage cap but no Medicare cap?

The Social Security wage cap exists because Social Security benefits are capped — higher earners do not receive proportionally higher benefits. Medicare benefits are not capped the same way, so there is no wage cap for the Medicare portion of FICA. This means high earners pay more into Medicare relative to their benefits.

Can I opt out of FICA?

No, with very few exceptions. FICA is mandatory for almost all workers. The only way to avoid it is to be in one of the exempt categories (certain government employees, railroad workers, or members of exempt religious groups). Most workers cannot opt out even if they disagree with the programs or believe they could invest the money better elsewhere.
