FICA is a 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 (retirement, disability, and survivor benefits) and Medicare (health insurance for people 65 and older, and some younger people with disabilities).

FICA is not optional. If you work as an employee, your employer is required by law to withhold FICA taxes from your pay and send them to the federal government. Self-employed people pay FICA taxes too, though they handle it differently — they pay both the employee and employer portions themselves when they file their tax return.

FICA taxes are separate from federal income tax. You will see both listed on your pay stub. FICA goes to Social Security and Medicare specifically. Federal income tax goes to the general Treasury and funds the broader operations of government.

Key Takeaways

  • FICA has two parts: 6.2% of your wages goes to Social Security, and 1.45% goes to Medicare, for a total of 7.65% withheld from your paycheck.
  • Your employer pays an equal amount (another 7.65%) on your behalf, though you do not see this on your pay stub.
  • Social Security taxes stop once you reach the annual wage cap, which changes each year; Medicare taxes do not have a cap.
  • Self-employed people pay both the employee and employer portions of FICA, totaling 15.3%, when they file their tax return.
  • FICA withholding is automatic and required — you cannot opt out, even if you do not plan to use Social Security or Medicare.

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%. Together, that is 7.65% of your paycheck withheld for FICA taxes.

Your employer also pays FICA taxes on your behalf — another 6.2% for Social Security and 1.45% for Medicare. This employer contribution does not reduce your paycheck, but it is part of your total compensation cost to the company. You can see the employer amount listed separately on your pay stub, usually labeled "employer FICA" or "employer Social Security" and "employer Medicare."

The Social Security wage base changes each year. In 2024, you pay Social Security tax only on the first $168,600 of your annual wages. Once you earn more than that in a calendar year, Social Security tax stops being withheld from your remaining paychecks. Medicare tax, by contrast, has no wage cap — it continues on every dollar you earn, no matter how much you make.

Where FICA money actually goes

Social Security taxes fund three separate programs. The largest is retirement benefits — monthly payments to people who have worked and reached full retirement age. The second is disability benefits (SSDI), paid to workers who become unable to work before retirement age and to their families. The third is survivor benefits, paid to the families of workers who die.

Medicare taxes fund the Medicare program, which provides hospital insurance (Part A), medical insurance (Part B), and prescription drug coverage (Part D) to people 65 and older. Medicare also covers some younger people with disabilities and people with end-stage renal disease.

The money you pay in FICA taxes does not sit in an account with your name on it. Social Security and Medicare operate on a pay-as-you-go system: the taxes collected from current workers pay the benefits of current retirees and beneficiaries. When you retire or become may be able to access for Medicare, your benefits come from the FICA taxes being paid by workers at that time.

FICA taxes for self-employed people

If you are self-employed, you pay FICA taxes when you file your annual tax return, not through paycheck withholding. You pay both the employee portion (7.65%) and the employer portion (7.65%), for a total of 15.3% of your net self-employment income.

You calculate self-employment tax on Schedule SE, which is part of your federal tax return. The amount you owe depends on your net profit from self-employment — your business income minus your business expenses. You can deduct half of your self-employment tax as a business expense on your return, which reduces your overall tax burden slightly.

Self-employed people must pay estimated taxes quarterly if they expect to owe $1,000 or more in federal taxes for the year. This includes self-employment tax. Paying quarterly prevents a large bill when you file your return and avoids underpayment penalties.

Why FICA taxes are withheld automatically

FICA withholding is mandatory because Social Security and Medicare are insurance programs funded by payroll taxes. Congress set the tax rates and wage bases in law, and employers are required to withhold and remit the money to the federal government.

You cannot opt out of FICA taxes, even if you do not plan to use Social Security or Medicare benefits. The only exception is for certain religious groups that have been granted exemption by the IRS, and even then the exemption applies only to self-employment tax, not to wages earned as an employee.

FICA withholding is separate from your federal income tax withholding. Your employer uses the W-4 form you complete to calculate federal income tax withholding, but FICA withholding is automatic and does not depend on your W-4 choices.

How FICA connects to your future benefits

The amount of Social Security retirement benefits you receive is based on your earnings record — the wages you earned over your working years on which you paid Social Security tax. Higher lifetime earnings mean higher benefits. The Social Security Administration tracks your earnings each year and uses your 35 highest-earning years to calculate your benefit amount.

To be may be able to access for Social Security retirement benefits, you must have earned at least 40 credits. One credit is earned for each $1,680 of wages in 2024 (the amount changes yearly). 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 contributions. Most people become may be able to access for Medicare at 65 if they have worked and paid Medicare taxes for at least 10 years (40 quarters). Some younger people with disabilities or end-stage renal disease may be may be able to access sooner.

FICA taxes on different types of income

FICA taxes apply to wages and salaries from employment. They also apply to tips you receive (your employer should withhold FICA on reported tips), bonuses, and most other forms of compensation for work.

FICA taxes do not apply to investment income like dividends, capital gains, or interest. They do not apply to income from rental property, though self-employment tax may apply if you actively manage rental properties as a business. Unemployment benefits, Social Security benefits, and some other government payments are not subject to FICA taxes.

If you have both W-2 wages and self-employment income, you pay FICA on both. However, if your combined FICA taxes exceed the annual maximum (which happens only at very high income levels), you may be able to claim a credit for the overpayment when you file your tax return.

Frequently Asked Questions

Can I get FICA taxes back if I do not use Social Security or Medicare?

No. FICA taxes fund insurance programs, not personal savings accounts. The money you pay in goes to the current beneficiaries of Social Security and Medicare. You cannot withdraw your contributions or pass them to your heirs if you do not use the benefits yourself.

What happens to FICA taxes if I work for multiple employers?

Each employer withholds FICA taxes on your wages. If your combined wages from all employers exceed the Social Security wage base for the year, you may overpay Social Security tax. You can claim a credit for the overpayment when you file your tax return, but you must file to get it back.

Do FICA taxes apply to gig work and side jobs?

If you receive a W-2 from a gig or side employer, FICA taxes are withheld like any other job. If you are paid as an independent contractor and receive a 1099, you owe self-employment tax (which includes FICA) on your net profit when you file your return.

Why do I still pay FICA if I am not planning to retire?

FICA funds not just retirement benefits but also disability and survivor benefits. If you become unable to work before retirement age, you may be may be able to access for disability benefits. If you die, your family may receive survivor benefits. These are insurance protections, not optional programs.

Does FICA tax change based on my income level?

The tax rate stays the same for everyone — 6.2% for Social Security and 1.45% for Medicare. However, Social Security tax stops once you reach the annual wage cap, so higher earners pay a smaller percentage of their total income in Social Security tax. Medicare tax has no cap and continues on all wages.
