FICA taxes are the Social Security and Medicare deductions on your paycheck

FICA stands for the Federal Insurance Contributions Act. It is the law that requires you and your employer to pay taxes that fund two programs: Social Security and Medicare. These taxes come out of your paycheck automatically — you will see them listed as "Social Security" and "Medicare" or sometimes as "FICA" on your pay stub. The money does not go into a personal account with your name on it. Instead, it goes into a federal fund that pays benefits to people who are retired, disabled, or have lost a spouse or parent.

FICA taxes are separate from federal income tax, which is also deducted from your paycheck. Many people confuse the two because they both appear on the same stub, but they fund different things and are calculated differently.

Key Takeaways

  • FICA taxes fund Social Security retirement benefits and Medicare health insurance for people age 65 and older.
  • You pay 6.2 percent of your wages for Social Security and 1.45 percent for Medicare; your employer pays the same amount.
  • Self-employed people pay both the employee and employer share, totaling 15.3 percent.
  • The money you pay in does not sit in an account waiting for you — it pays current beneficiaries, and future workers will pay for your benefits when you retire.

How much FICA tax comes out of your paycheck

The Social Security portion is 6.2 percent of your gross wages, up to a cap. In 2024, that cap is $168,600 — meaning once you earn that much in a year, no more Social Security tax is taken out for the rest of that year. Medicare tax is 1.45 percent of all your wages with no cap, so you pay it on every dollar you earn.

Your employer pays an equal amount: 6.2 percent for Social Security and 1.45 percent for Medicare. That money is also sent to the federal government. If you are self-employed, you pay both the employee and employer share yourself, which totals 15.3 percent (though you can deduct half of it on your tax return).

The exact dollar amount that comes out depends on how much you earn. If you make $2,000 in a paycheck, you pay $124 in Social Security tax and $29 in Medicare tax. If you make $5,000, you pay $310 and $72.50.

What Social Security tax pays for

Social Security is a retirement and disability insurance program. The tax you pay funds monthly checks for people who are retired, people who became disabled before retirement age, and surviving family members of workers who died. You do not build up a personal account — the money you pay in this year goes to pay people receiving benefits right now.

When you reach retirement age (currently 66 or 67 depending on your birth year), you become may be able to access to receive a monthly Social Security check based on how much you earned during your working years and how long you worked. If you become disabled before retirement, you may receive benefits sooner. If you die, your spouse and children may receive survivor benefits.

What Medicare tax pays for

Medicare is health insurance for people age 65 and older. The Medicare tax you pay funds hospital insurance (Part A), which covers inpatient hospital stays, skilled nursing, and hospice care. It also contributes to the overall Medicare program, though Medicare Part B (doctor visits and outpatient care) and Part D (prescription drugs) are funded partly through beneficiary premiums as well.

You do not have to wait until retirement to pay Medicare tax — it starts as soon as you begin working. But you do not receive Medicare benefits until you turn 65, unless you have been receiving Social Security disability benefits for 24 months or have end-stage renal disease.

Why FICA taxes are mandatory

FICA taxes are required by federal law. Your employer must withhold them from your paycheck and send them to the Internal Revenue Service (IRS). You cannot opt out, even if you disagree with the programs or believe you will not need them later. The only exception is certain religious groups that have received a formal exemption from the IRS, which is rare and requires a specific application process.

The reason these taxes are mandatory is that Social Security and Medicare are insurance programs designed to spread risk across the entire working population. If participation were voluntary, younger and healthier workers might not pay in, which would leave the programs without enough money to pay current beneficiaries.

How FICA taxes appear on your pay stub

Your pay stub will show FICA taxes in a deductions section. You will typically see two line items: one for Social Security (labeled "Social Security" or "OASDI," which stands for Old Age, Survivors, and Disability Insurance) and one for Medicare. Some stubs also show the employer's share, though that money does not come from your paycheck — it is paid separately by your employer.

If you work for multiple employers in the same year, each one withholds Social Security tax up to the annual cap. This can result in overpayment if your combined earnings exceed the cap. You can claim a credit for the overpayment when you file your federal income tax return.

Frequently Asked Questions

Yes. Tips are considered wages and are subject to FICA taxes. Your employer should withhold FICA taxes on tips you report, or you may owe them when you file your tax return if tips were not withheld.

Why is there a Social Security tax cap but not a Medicare cap?

The cap on Social Security tax exists because Social Security benefits are calculated based on your earnings history, and there is a maximum benefit amount. Medicare has no cap because it is designed as health insurance for all seniors, regardless of how much they earned.
