FICA stands for Federal Insurance Contributions Act, a U.S. federal law that mandates payroll taxes to fund two critical social safety net programs: Social Security and Medicare. what is fica tax Enacted in 1935 as part of the Social Security Act, FICA ensures that workers contribute to a system that provides retirement benefits, disability insurance, survivor benefits, and healthcare for seniors.

The FICA tax is a payroll deduction taken from your wages before you receive your paycheck. It’s not optional—both employees and employers are required to contribute, and the amounts are set by federal law. For 2025, the FICA tax comprises two parts:

Social Security Tax: This funds retirement benefits, disability insurance, and survivor benefits for workers and their families. It’s calculated at 6.2% of your wages, up to a wage base limit of $176,100 for 2025.
Medicare Tax: This supports healthcare for individuals aged 65 and older, as well as certain disabled individuals. It’s calculated at 1.45% of all wages, with no income cap. High earners may also face an Additional Medicare Tax of 0.9% on wages exceeding $200,000 (single) or $250,000 (married filing jointly).

Together, these taxes total 7.65% of your wages (6.2% + 1.45%) for most employees, assuming your income is below the Social Security wage cap. Employers match this contribution, effectively doubling the amount paid into the system.

Why Does FICA Matter?

Employees: If you work for a company, your employer withholds 7.65% of your wages for FICA and matches that amount. You’ll see this as “FICA,” “OASDI” (Old-Age, Survivors, and Disability Insurance), or “Medicare” on your pay stub.
Self-Employed Individuals: Freelancers, contractors, and business owners pay the full 15.3% (6.2% + 1.45% x 2) as the Self-Employment Tax, covering both the employee and employer portions. However, they can deduct half of this tax as a business expense.
Certain Exempt Groups: Some workers, like certain nonresident aliens, students employed by their schools, or federal employees hired before 1984 under the Civil Service Retirement System, may be exempt from parts of FICA.

How Is FICA Tax Calculated?

Let’s break down how FICA taxes are computed with a few examples for 2025:

Example 1: Salaried Employee Earning $50,000 Annually

Social Security Tax: 6.2% of $50,000 = $3,100
Medicare Tax: 1.45% of $50,000 = $725
Total FICA Tax: $3,100 + $725 = $3,825
Employer Contribution: Matches the $3,825
Total Paid to System: $7,650

Your take-home pay is reduced by $3,825 annually, or about $319 per month if paid monthly.

Example 2: High Earner Making $250,000

Social Security Tax: 6.2% of $176,100 (wage cap) = $10,918.20
Medicare Tax: 1.45% of $250,000 = $3,625
Additional Medicare Tax: 0.9% of ($250,000 – $200,000) = $450
Total FICA Tax: $10,918.20 + $3,625 + $450 = $14,993.20
Employer Contribution: Matches $10,918.20 + $3,625 = $14,543.20 (no match for Additional Medicare Tax)

Here, your paycheck deductions total nearly $15,000, with the employer covering a similar amount.

Example 3: Self-Employed Freelancer Earning $80,000

Self-Employment Tax: 15.3% of $80,000 = $12,240
Deductible Portion: Half of $12,240 = $6,120 (deducted from taxable income)
Net Tax Impact: $12,240, but the deduction lowers overall tax liability.

These examples show how FICA scales with income and varies by employment type. Check your pay stub or consult a tax professional to confirm your deductions.
