FICA deduction is the money your employer takes from each paycheck for Social Security and Medicare

When you see "FICA" on your pay stub, it means your employer is withholding a percentage of your gross pay to fund two federal programs: Social Security and Medicare. FICA stands for the Federal Insurance Contributions Act, the law that requires this withholding. The money does not go into a personal account with your name on it — it goes into a general fund that pays current beneficiaries and covers your future may be able to access.

The deduction happens automatically once you start a job. You do not have to do anything to trigger it. Your employer calculates the amount based on your wages and sends it to the Internal Revenue Service (IRS) on your behalf, along with a matching amount the employer pays separately.

Key Takeaways

  • FICA deduction splits into two parts: 6.2% for Social Security and 1.45% for Medicare, taken from your paycheck before taxes.
  • Your employer also pays an equal FICA amount on your behalf, so the total contribution is double what you see deducted.
  • Self-employed people pay both the employee and employer portions themselves, totaling 15.3% of net earnings.
  • FICA contributions build your record toward Social Security retirement benefits and Medicare coverage at age 65.

How much FICA comes out of your paycheck

The employee portion of FICA is 7.65% of your gross pay. This breaks into two parts: 6.2% goes to Social Security and 1.45% goes to Medicare. If you earn $1,000 in a week, FICA deduction is $76.50.

Social Security has a wage cap, which means once you earn a certain amount in a calendar year, the 6.2% Social Security portion stops being deducted. The Medicare portion (1.45%) has no cap and continues on all earnings. Additionally, if your income exceeds $200,000 (or $250,000 if married filing jointly), you pay an extra 0.9% Medicare tax on the amount above that threshold.

Your employer also contributes 7.65% on your behalf — the same rate you pay. This employer contribution does not show on your pay stub as a deduction, but it is part of your total FICA cost to the system.

The difference between FICA and income tax withholding

FICA and federal income tax withholding are separate deductions that both appear on your pay stub. FICA funds Social Security and Medicare specifically. Federal income tax withholding funds general government operations and is calculated differently based on the W-4 form you fill out when hired.

You can change your federal income tax withholding by submitting a new W-4 to your employer, but you cannot opt out of FICA. FICA is mandatory for all employees earning wages. The only exception is certain religious groups and some government employees, depending on their specific employment status.

FICA for self-employed people

If you are self-employed, you pay both the employee and employer portions of FICA yourself. This is called self-employment tax, and it totals 15.3% of your net earnings (after business expenses). You calculate and pay this tax when you file your annual tax return using Schedule SE.

Self-employed people can deduct half of their self-employment tax as a business expense on their tax return, which reduces their taxable income. This deduction roughly mirrors the fact that an employer's FICA contribution is not counted as income to the employee.

What FICA contributions pay for

Your FICA contributions build your record toward two programs. The Social Security portion (6.2%) funds retirement benefits, disability benefits, and survivor benefits for your family if you die. The Medicare portion (1.45%) funds hospital insurance (Part A) and is one piece of your may be able to access for Medicare at age 65.

The amount of Social Security retirement benefit you receive depends on how much you earned during your working years and how long you contributed. Medicare may be able to access at 65 requires a minimum number of quarters of FICA contributions, typically 40 quarters (10 years) of work.

How to read FICA on your pay stub

Your pay stub lists FICA as a line item under deductions. It may show as a single "FICA" line or split into "Social Security" and "Medicare" lines. The amount should be 6.2% of your gross pay for Social Security and 1.45% for Medicare, unless you have already hit the Social Security wage cap for the year.

If you notice FICA is not being deducted, contact your employer's payroll department. FICA withholding is required by law, and an employer who does not withhold it is breaking federal law and putting your future benefits at risk. If you are an independent contractor receiving a 1099 form instead of a W-2, you are responsible for paying self-employment tax yourself when you file your return.

FICA deduction and your tax return

FICA deductions are already withheld from your paycheck, so they do not reduce your taxable income the way some other deductions do. However, when you file your tax return, the FICA you paid is recorded and credited to your Social Security account. The IRS matches the FICA shown on your W-2 form (which your employer sends) to your Social Security number.

You cannot claim FICA as a deduction on your tax return to lower your taxes owed. It is a separate system. However, if you overpaid FICA — for example, by working for two employers in the same year and hitting the Social Security wage cap twice — you can claim a credit for the overpayment when you file.

Frequently Asked Questions

Can I opt out of FICA deduction?

No. FICA withholding is mandatory for all employees. The only exceptions are certain members of recognized religious groups that have filed for exemption and some government employees hired before specific dates. If you are a regular employee, FICA comes out of every paycheck.

What happens to FICA if I change jobs?

Your FICA contributions continue with each new employer. Each employer withholds and reports FICA separately, but it all goes into the same Social Security and Medicare accounts tied to your Social Security number. Changing jobs does not reset or interrupt your FICA record.

Do I get FICA back if I leave the country?

FICA contributions are not refundable like income tax overpayments. However, if you worked in the United States and paid FICA, you may still be may have access to to Social Security or Medicare benefits depending on how long you contributed and the agreements between the U.S. and your country of residence. Contact the Social Security Administration for details about your specific situation.

Why do I owe self-employment tax if I already paid FICA at a job?

Self-employment tax and employee FICA are separate. If you work a W-2 job and also have self-employment income, you pay FICA on the W-2 wages and self-employment tax on the net self-employment income. Both contributions count toward your Social Security and Medicare record.

Does FICA come out before or after federal income tax?

FICA is calculated on your gross pay (before federal income tax). Both FICA and federal income tax are withheld from your paycheck, but FICA is not reduced by income tax withholding. Your gross pay is the starting point for both calculations.
