If you see FICA on your paycheck, it refers to a mandatory federal payroll tax
FICA stands for Federal Insurance Contributions Act. It is the law that requires employers to withhold payroll taxes to fund Social Security and Medicare.
When FICA appears on your paystub, it means part of your wages is being withheld to support these federal benefit programs.
What Does FICA Pay For?
FICA funds two major programs.
Social Security (OASDI)
OASDI covers:
• Retirement benefits
• Disability insurance (SSDI)
• Survivor benefits
Medicare
This provides federal health insurance coverage for:
• Individuals age 65 and older
• Certain younger individuals with disabilities
Together, these programs provide long-term financial and healthcare support.
How Much Is FICA Tax in 2026?
FICA tax is made up of two components.
Social Security (OASDI)
6.2% of wages (employee portion)
6.2% paid by employer
Subject to an annual wage limit
Medicare
1.45% of wages (employee portion)
1.45% paid by employer
No wage limit
Total employee FICA rate:
7.65% of gross wages
Your employer matches this 7.65%, meaning 15.3% is contributed overall.
High earners may also pay:
Additional Medicare Tax (0.9%)
Applied to income above federal thresholds
Why Is FICA Deducted From My Paycheck?
FICA is required by federal law for most employees in the United States.
It is automatically withheld from your paycheck and sent to the IRS.
Unlike federal income tax, you generally cannot adjust or opt out of FICA withholding.
The purpose is to ensure funding for:
• Retirement income
• Disability benefits
• Medicare healthcare coverage
Is FICA the Same as Social Security?
Not exactly.
FICA is the overall payroll tax law.
Social Security is one part of FICA.
Your paycheck may show:
• FICA
• FICA SS
• OASDI
• Social Security
• FICA MED
• Medicare
Some payroll systems combine the two into one line labeled FICA. Others separate them into Social Security and Medicare.
What Is the Difference Between FICA and Federal Income Tax?
This is a common source of confusion.
FICA:
• Fixed percentage rate
• Funds Social Security and Medicare
• Mandatory for most workers
Federal Income Tax (often shown as FIT or FITW):
• Based on your income tax bracket
• Determined by your Form W-4 elections
• Funds general federal government operations
They are separate taxes and calculated differently.
Does FICA Reduce My Take-Home Pay?
Yes.
FICA is deducted from your gross wages before you receive your net pay.
Example:
If you earn $2,000 in gross pay:
7.65% FICA = $153 deducted
That amount reduces your take-home pay, along with other taxes and voluntary deductions.
Why Did My FICA Deduction Change?
Your FICA amount may change if:
• Your gross pay increased or decreased
• You worked overtime or fewer hours
• You reached the Social Security wage base limit
• You exceeded Medicare high-income thresholds
• You changed jobs during the year
Once you reach the annual Social Security wage base limit, the 6.2% Social Security portion stops for the rest of the calendar year. Medicare tax continues.
Who Does Not Pay FICA?
Certain individuals may be exempt, including:
• Some state and local government employees covered by alternative retirement systems
• Certain nonresident aliens
• Members of qualifying religious groups
• Some student employees working for their university
However, most U.S. employees are required to pay FICA.
Where Can You Verify FICA Information?
Official sources include:
• Internal Revenue Service (IRS)
• Social Security Administration (SSA)
Your Form W-2 will show:
• Social Security wages
• Social Security tax withheld
• Medicare wages
• Medicare tax withheld
