FICA is the tax that funds Social Security and Medicare
FICA stands for the Federal Insurance Contributions Act. It is a payroll tax that your employer withholds from your paycheck every pay period. The money goes to two programs: Social Security and Medicare. You will see FICA listed on your pay stub as two separate line items: Social Security tax and Medicare tax.
FICA is not optional. If you are employed and earn a wage, your employer is required by law to withhold it. The amount depends on your gross pay — the total you earn before any deductions. Self-employed people pay FICA too, though they handle it differently at tax time.
The reason FICA exists is that Social Security and Medicare are insurance programs you pay into while working. When you retire, become disabled, or reach age 65, you draw benefits from the money you and your employer contributed. FICA is how the government funds those benefits for current retirees and disabled workers.
Key Takeaways
- FICA withholds 6.2% of your wages for Social Security and 1.45% for Medicare, for a total of 7.65% from your paycheck.
- Your employer also pays an equal amount (7.65%) on your behalf, though you do not see this on your pay stub.
- Social Security tax stops once you reach the annual wage cap, which changes each year; Medicare tax does not have a cap.
- Self-employed workers pay both the employee and employer portions (15.3% total) when they file their tax return.
- FICA withholding appears on your W-2 form at the end of the year and is reported to the IRS.
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. If you earn $1,000 in a pay period, FICA withholding is $76.50.
Your employer also pays an equal 7.65% on your behalf — but this does not come out of your paycheck. It is a separate cost to the employer. So the total FICA contribution is 15.3%, split evenly between you and your employer.
The Social Security portion (6.2%) only applies to wages up to a certain limit each year. That limit is called the wage base, and it changes annually. Once you earn more than the wage base in a calendar year, Social Security tax stops being withheld from your remaining paychecks that year. Medicare tax, by contrast, has no wage cap — it continues on every dollar you earn, no matter how much you make.
Where your FICA money goes
The 6.2% Social Security portion funds retirement benefits, survivor benefits (paid to your family if you die), and disability benefits. When you turn 62 or older, you can begin drawing Social Security retirement benefits based on how much you paid in and how long you worked. If you become disabled before retirement age, you may receive Social Security Disability Insurance (SSDI) benefits.
The 1.45% Medicare portion funds hospital insurance (Part A), which covers inpatient hospital stays, skilled nursing care, and hospice. If you are 65 or older, or disabled and receiving Social Security benefits for two years, you become covered by Medicare automatically. Higher-income earners pay an additional 0.9% Medicare tax on wages above a certain threshold, though this is a separate calculation.
FICA taxes are held in trust funds managed by the Social Security Administration and the Centers for Medicare & Medicaid Services. The money is not set aside in an individual account with your name on it. Instead, current FICA collections pay current beneficiaries, and future collections will pay you when you are may be able to access.
How FICA appears on your pay stub and tax forms
On your pay stub, you will see two lines under deductions: one for Social Security tax and one for Medicare tax. These show the amount withheld from that specific paycheck. Some pay stubs also show year-to-date totals, so you can track how much FICA has been withheld since January 1.
At the end of the year, your employer sends you a W-2 form (Wage and Tax Statement). Box 4 shows total Social Security tax withheld, and Box 6 shows total Medicare tax withheld. These amounts are also reported to the IRS, so the government knows how much FICA you paid. When you file your income tax return, the IRS cross-checks your return against your W-2 to make sure the numbers match.
If you are self-employed, you do not receive a W-2. Instead, you report your net self-employment income on Schedule SE (Self-Employment Tax) when you file your tax return. This is where you calculate and pay both the employee and employer portions of FICA — 15.3% total — though you can deduct half of it as a business expense.
What happens if you overpay FICA
If you work for more than one employer in the same year, or if you earn more than the Social Security wage base, you might overpay Social Security tax. This happens because each employer withholds 6.2% up to the wage base independently — they do not know what you earned at your other job.
When you file your income tax return, the IRS calculates the correct total Social Security tax you should have paid. If you overpaid, you receive a credit on your return, which may result in a refund. You do not have to do anything special to claim this credit — the IRS handles it automatically when processing your return.
Medicare tax overpayment is rare, since there is no wage cap. However, if you owe the additional 0.9% Medicare tax on high income and your employer did not withhold it, you will owe it when you file your return.
FICA and your Social Security record
Every time you pay FICA, the Social Security Administration records it under your Social Security number. This creates a work history that determines how much Social Security retirement or disability benefit you will receive later. The amount is based on your highest 35 years of earnings (for retirement) or your recent work history (for disability).
You can view your Social Security earnings record online at ssa.gov by creating a my Social Security account. This record shows how much you paid in Social Security tax each year. It is worth checking periodically to make sure the amounts are correct, because errors can reduce your future benefits. If you spot a mistake, you can contact the Social Security Administration to correct it.
Frequently Asked Questions
Can I opt out of paying FICA?
No. FICA is mandatory for all employees and self-employed workers. The only exceptions are certain religious groups that have received a formal exemption from the IRS, and some nonresident aliens on temporary visas. If you are a U.S. citizen or permanent resident working in the United States, you must pay FICA.
Why do I pay FICA if I do not plan to collect Social Security?
FICA funds not only retirement benefits but also disability insurance and survivor benefits. Even if you never collect retirement benefits, your family receives survivor benefits if you die, and you are covered by disability insurance if you become unable to work. Additionally, FICA is a legal requirement — you cannot choose to skip it based on your personal plans.
Does FICA get refunded when I retire?
No. FICA is not a savings account that gets returned to you. Instead, you receive monthly Social Security benefits based on your earnings record and age. The amount you receive depends on how much you paid in and when you start collecting, not on a direct refund of what you contributed.
What is the difference between FICA and income tax?
FICA and federal income tax are two separate withholdings. FICA funds Social Security and Medicare. Federal income tax funds general government operations. Both are withheld from your paycheck, but they go to different places and are calculated differently. FICA is a flat percentage; income tax varies based on your tax bracket and withholding elections.
If I work part-time, do I still pay FICA?
Yes. FICA is withheld on all wages, regardless of whether you work full-time or part-time. The percentage (7.65%) is the same. If you earn $200 in a part-time job, FICA withholding is $15.30, just as it would be for any other wage.
