FICA taxes are Social Security and Medicare payroll deductions taken from your paycheck

FICA stands for the Federal Insurance Contributions Act. It is the law that requires employers to withhold money from your wages for two programs: Social Security and Medicare. If you are self-employed, you pay both the employer and employee portions yourself. The money comes out of your paycheck before you see it, and your employer sends it to the federal government.

FICA is not optional. Every employer must withhold it from employees' pay, with rare exceptions for certain religious groups and some government workers. The amount withheld depends on your income and filing status, and it funds benefits you may receive later in life or if you become disabled.

Key Takeaways

  • FICA has two parts: Social Security (6.2% of wages) and Medicare (1.45% of wages), taken from your paycheck by your employer.
  • Your employer matches the amount you pay, sending the total to the federal government on your behalf.
  • Self-employed people pay both portions themselves, totaling 15.3% of net earnings.
  • FICA withholding is separate from federal income tax and is based on your gross wages, not your tax bracket.
  • You can see how much FICA you paid each year on your W-2 form or tax return.

How much FICA comes out of your paycheck

Your employer withholds 6.2% of your gross wages for Social Security and 1.45% for Medicare. That is 7.65% total from your paycheck. Your employer then pays an equal amount (another 7.65%) on your behalf, which you do not see but which counts toward your benefits.

There is a cap on Social Security withholding. In 2024, you stop paying the 6.2% Social Security tax once your wages reach $168,600 for the year. After that point, only Medicare tax (1.45%) continues. Medicare tax has no income cap — you pay it on all wages, no matter how high.

If you are self-employed, you pay both the employee and employer portions yourself. That means 12.4% for Social Security (up to the wage cap) and 2.9% for Medicare, totaling 15.3% of your net self-employment income. You can deduct half of this amount when you file taxes.

What FICA money funds

Social Security taxes fund retirement benefits, disability benefits, and survivor benefits for your family if you die. Medicare taxes fund hospital insurance (Part A), which covers inpatient hospital stays, skilled nursing care, and hospice. The money you pay goes into a trust fund, and current workers' contributions pay benefits to current retirees and disabled people.

You do not have a personal account holding your FICA contributions. The system is pay-as-you-go: money collected today pays today's beneficiaries. Your future benefits depend on how much you paid in over your working years and when you choose to start receiving them.

Where to find your FICA withholding information

Your pay stub shows FICA withholding for that pay period. Look for lines labeled "Social Security" or "OASDI" (Old-Age, Survivors, and Disability Insurance) and "Medicare" or "Med." These show what came out of that specific paycheck.

Your W-2 form, which your employer sends in January, shows total FICA withheld for the entire year in boxes 4 (Social Security tax) and 6 (Medicare tax). If you are self-employed, you report self-employment tax on Schedule SE when you file your tax return. Your Social Security statement, available at ssa.gov, also shows your lifetime FICA contributions and estimated future benefits.

FICA versus federal income tax withholding

FICA and federal income tax are separate deductions. FICA is a fixed percentage based on your wages and goes to Social Security and Medicare. Federal income tax withholding is based on your W-4 form and your tax bracket, and it goes to the general Treasury. You can have different amounts withheld for each one.

Some people owe federal income tax at tax time even though FICA was withheld correctly, because they did not have enough income tax withheld. Others get a refund. FICA withholding does not work that way — you pay a set percentage, and there is no refund or additional payment due based on your tax return (except in rare cases of overpayment due to multiple employers).

Who does not pay FICA

Most workers pay FICA, but some groups are exempt. Members of certain religious groups that object to insurance on principle can request exemption from both Social Security and Medicare. Some federal employees hired before 1984 pay into a different retirement system instead. State and local government employees sometimes have their own pension systems and do not pay FICA.

Students employed by their school, some work-study employees, and certain family members working in a family business may be exempt in specific situations. If you think you might be exempt, check with your employer or the Social Security Administration, because missing FICA contributions can affect your future benefits.

What happens if you overpay FICA

If you work for more than one employer in the same year, you might pay more Social Security tax than the annual cap allows. For example, if you earned $100,000 at one job and $80,000 at another, you would have paid Social Security tax on $180,000 total, but the 2024 cap is $168,600. You can claim a credit for the overpayment when you file your tax return.

You cannot get a refund directly, but the overpayment reduces your federal income tax liability. If you are self-employed and overpay, you claim the credit on Schedule SE. Keep your W-2 forms and pay stubs to document the overpayment when you file.

Frequently Asked Questions

Can I opt out of paying FICA?

No, unless you are in a specific exempt group such as members of certain religious organizations that object to insurance. Most workers have no choice — FICA withholding is required by law. If you believe you may have access to for an exemption, contact the Social Security Administration or your employer's payroll department.

Does FICA withholding count toward my income tax refund?

No. FICA and federal income tax are separate. FICA goes to Social Security and Medicare, not to your income tax account. Your income tax refund depends only on how much federal income tax was withheld, not on FICA. You cannot use FICA payments to reduce taxes owed.

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

Contact your employer immediately and ask why. Employers are required by law to withhold FICA. If your employer refuses or continues not to withhold, you can report it to the Department of Labor or the IRS. Missing FICA contributions can affect your Social Security record and future benefits.

Do I pay FICA on tips?

Yes. Tips are considered wages, and FICA is withheld on them. You should report all tips to your employer so they can withhold the correct amount. If you do not report tips, you may underpay FICA and have a gap in your Social Security record.

How much FICA will I pay over my lifetime?

That depends on your income and how long you work. The amount varies widely. Your Social Security statement at ssa.gov shows your lifetime contributions so far and estimates your future benefits based on your current earnings record.
