FICA is the tax that funds Social Security and Medicare

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

FICA has two parts. The Social Security portion is 6.2% of your wages, and your employer pays another 6.2% on your behalf — that is 12.4% total. The Medicare portion is 1.45% from your paycheck and 1.45% from your employer, for 2.9% total. If you earn over a certain amount (the threshold changes yearly), you pay an additional 0.9% Medicare tax on the excess, and your employer does not match it.

Unlike income tax, which varies based on your filing status and deductions, FICA is the same percentage for almost everyone. You pay it whether you owe federal income tax or not. Self-employed people pay both the employee and employer share themselves — 15.3% total for Social Security and Medicare combined.

Key Takeaways

  • FICA tax funds Social Security retirement benefits and Medicare health coverage, not general government spending.
  • You pay 6.2% for Social Security and 1.45% for Medicare from each paycheck, and your employer matches both amounts.
  • FICA is withheld automatically and is separate from federal income tax — you cannot avoid it by claiming exemptions.
  • The money you pay in now determines how much Social Security and Medicare you can draw later, based on your earnings record.

How much FICA you pay depends on your gross wages

FICA is calculated on your gross pay — the amount before income tax, health insurance premiums, or other deductions come out. If you earn $50,000 a year, you pay 6.2% of $50,000 toward Social Security, which is $3,100. Your employer also pays $3,100 into the Social Security trust fund on your behalf.

There is a wage cap for Social Security only. In 2024, you pay Social Security tax on earnings up to $168,600. Once you reach that amount in a calendar year, your employer stops withholding the 6.2% Social Security tax from the rest of your paychecks that year. Medicare has no wage cap, so you pay 1.45% on all earnings, no matter how high.

If you work for multiple employers in the same year, each one withholds FICA based on what you earn from them. You might overpay Social Security tax if your combined earnings exceed the wage cap. When that happens, you can claim a credit on your tax return to get the overpayment back.

FICA creates a record that determines your future benefits

The Social Security Administration tracks how much FICA you pay each year. This record is called your earnings record. When you turn 62, 67, or 70 (depending on when you want to start), Social Security calculates your retirement benefit based on your 35 highest-earning years. The more you paid in, the larger your monthly check will be.

If you become disabled or die, Social Security uses your earnings record to determine whether you or your family members are may have access to to benefits. You need a minimum amount of work credits — which you earn by paying FICA — to may have access to. Most people need 40 credits (roughly 10 years of work) to get retirement benefits, though younger workers need fewer credits to may have access to for disability or survivor benefits.

You can view your earnings record online at ssa.gov by creating a my Social Security account. The record shows how much FICA you paid each year and estimates what your benefits might be. If you spot an error — a missing year, a wrong amount, or earnings credited to the wrong person — you can contact Social Security to correct it, though you usually have only three years to do so.

FICA is separate from federal income tax

Many people confuse FICA with federal income tax because both come out of the paycheck. They are different. Federal income tax goes to the general Treasury and funds government operations. FICA goes to two specific trust funds and is tied to future benefits you or your family will receive.

The amount of federal income tax withheld depends on your W-4 form, your filing status, and how many dependents you claim. You can adjust your withholding by changing your W-4 at any time. FICA, by contrast, is fixed. You cannot reduce it by claiming exemptions or changing your W-4. It comes out the same way for everyone at the same income level.

If you are self-employed, you pay both FICA and federal income tax, but you handle them differently. You pay FICA (called self-employment tax) when you file your annual tax return. You also pay estimated federal income tax four times a year. Self-employment tax is higher because you pay both the employee and employer share of FICA.

Some workers do not pay FICA

Most employees pay FICA, but some groups are exempt. Federal employees hired before 1984 do not pay Social Security tax (though they pay Medicare). Railroad workers pay into a separate system instead of Social Security. Some religious groups that object to insurance programs can request exemption from both Social Security and Medicare tax.

Students employed by the school or university where they are enrolled do not pay FICA on those wages. Certain nonresident aliens on specific visa types are exempt. If you work for a state or local government, you might not pay Social Security tax if your employer has its own pension system, though you would still pay Medicare.

If you think you should be exempt, check with your employer's payroll department. Exemptions are rare and usually require paperwork filed with the IRS. Most people who see FICA withheld are required to pay it.

What happens to FICA money after it is withheld

Your employer sends the FICA you paid, plus their matching share, to the U.S. Treasury on your behalf. The money goes into two trust funds: the Old-Age and Survivors Insurance Trust Fund (for Social Security retirement and survivor benefits) and the Federal Hospital Insurance Trust Fund (for Medicare Part A, which covers hospital stays).

These are not savings accounts in your name. The money is pooled with everyone else's FICA contributions. Current retirees and disabled workers draw from these funds now. When you retire, future workers' FICA contributions will help pay your benefits. This is why Social Security and Medicare are sometimes called "pay-as-you-go" systems.

The trust funds publish annual reports showing how much money comes in from FICA and how much goes out in benefits. Both funds face long-term funding challenges because the population is aging and fewer workers are paying in relative to the number of people drawing benefits. Congress periodically debates changes to FICA rates, wage caps, or benefit formulas, but no changes have been made to the basic structure in decades.

Frequently Asked Questions

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

No. FICA is not a personal savings account you can withdraw from. If you move abroad and never return to work in the U.S., you lose the credits you earned unless you come back and work long enough to reach the 40-credit threshold for retirement benefits. Some countries have agreements with the U.S. that allow people to combine work credits, but this is rare.

Why do I pay FICA if I will not collect Social Security?

You pay FICA because it is required by law for almost all employees. Even if you do not plan to collect Social Security, you are building credits that protect you if you become disabled or that your family can use if you die. Your spouse and children may be may have access to to survivor benefits based on your earnings record.

Does FICA come out before or after my paycheck deductions?

FICA is calculated on your gross pay before most deductions. However, certain pre-tax deductions like health insurance premiums and 401(k) contributions reduce the amount FICA is calculated on. This is why your FICA withholding might be slightly lower if you contribute to a retirement plan.

What if my employer did not withhold FICA from my paycheck?

Contact your employer's payroll department immediately. They are legally required to withhold FICA. If they did not, you and your employer are both liable for the unpaid amount, plus penalties and interest. The IRS and Social Security Administration track this, and it will affect your benefits record if the withholding is not corrected.

Does FICA apply to tips and bonuses?

Yes. FICA is withheld on all wages, including tips you report to your employer and bonuses. If you receive cash tips that you do not report, those are not subject to FICA withholding, but you are still legally required to report them as income and pay FICA on them when you file your tax return.
