FICA
FICA (Federal Insurance Contributions Act)
Quick Definition
FICA (Federal Insurance Contributions Act) is the federal law that mandates payroll taxes to fund Social Security and Medicare. Employees pay 7.65% of their wages, and employers match that amount for a combined 15.3% — the same total rate self-employed individuals pay as the "self-employment tax."
What It Means
FICA taxes are among the most universal taxes in America — they apply to virtually every paycheck regardless of income. Unlike the federal income tax, which has a standard deduction and progressive rates, FICA applies to the first dollar of earned income.
For most lower and middle-income workers, FICA taxes actually exceed their federal income tax. A worker earning $40,000 pays $3,060 in employee FICA (7.65%) but may owe very little federal income tax after the standard deduction reduces taxable income significantly.
FICA Components
| Tax | Rate (Employee) | Rate (Employer) | Combined | Wage Base |
|---|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% | First $168,600 (2024) |
| Medicare | 1.45% | 1.45% | 2.9% | All wages (no cap) |
| Additional Medicare | 0.9% | 0% | 0.9% | Wages above $200K (single) / $250K (MFJ) |
| Total (up to SS cap) | 7.65% | 7.65% | 15.3% |
The Social Security Wage Base
Social Security tax applies only to the first $168,600 of wages in 2024. This cap increases annually with wage inflation:
| Year | Social Security Wage Base |
|---|---|
| 2020 | $137,700 |
| 2021 | $142,800 |
| 2022 | $147,000 |
| 2023 | $160,200 |
| 2024 | $168,600 |
Once a worker's wages exceed $168,600, they stop paying the 6.2% Social Security portion — but the 1.45% Medicare tax continues on all wages with no cap.
High earner example: $250,000 annual salary:
- Social Security: $168,600 × 6.2% = $10,453
- Medicare (regular): $250,000 × 1.45% = $3,625
- Additional Medicare: $50,000 × 0.9% = $450
- Total employee FICA: $14,528
FICA for Self-Employed: The Self-Employment Tax
Self-employed individuals pay both the employee and employer portions, resulting in a 15.3% self-employment (SE) tax on net self-employment income:
| Component | Rate |
|---|---|
| Social Security (both portions) | 12.4% (on first $168,600) |
| Medicare (both portions) | 2.9% (on all SE income) |
| Additional Medicare | +0.9% (on SE income above $200K single) |
| Total SE Tax (below SS cap) | 15.3% |
SE Tax Calculation Example: $80,000 net self-employment income:
- Net SE income × 92.35% = $73,880 (reduces the base by the employer-equivalent deduction)
- SE tax: $73,880 × 15.3% = $11,304
The SE Tax Deduction: Self-employed individuals can deduct 50% of SE tax as an above-the-line deduction from AGI ($5,652 in the example above). This mirrors the employer's ability to deduct payroll taxes as a business expense.
FICA vs. Federal Income Tax
For many workers, FICA exceeds their federal income tax burden:
Example: Single worker earning $35,000
| Tax | Calculation | Amount |
|---|---|---|
| Federal income tax | $35,000 - $14,600 standard deduction = $20,400 taxable; 10% × $11,600 + 12% × $8,800 = $2,216 | $2,216 |
| FICA (employee portion) | $35,000 × 7.65% | $2,678 |
| FICA exceeds income tax | by $462 |
For the majority of American workers, the FICA burden rivals or exceeds their federal income tax.
FICA and Retirement Benefit Earning
FICA contributions are not just taxes — they earn Social Security credits. Workers earn one credit for each $1,730 in 2024 wages (up to 4 credits per year). A full Social Security retirement benefit requires 40 credits (10 years of work).
Higher lifetime Social Security wages generally produce higher monthly benefits. The Social Security Administration calculates benefits based on the 35 highest-earning years, adjusted for wage inflation.
FICA Exemptions
Not all workers pay FICA:
| Worker Type | FICA Status |
|---|---|
| Most employees | Pay full FICA |
| Self-employed | Pay SE tax (equivalent) |
| Student employees at their university | Exempt from FICA while enrolled |
| Certain visa holders (F-1, J-1) | Exempt for first 5 years |
| Certain railroad employees | Different Railroad Retirement Tax |
| Some state/local government workers | Some jurisdictions opted out before 1984 |
| Certain religious workers | Ministers can opt out with specific filing |
Key Points to Remember
- FICA funds Social Security (6.2%) and Medicare (1.45%) — total 7.65% for employees, matched by employers
- Social Security tax caps at the $168,600 wage base (2024); Medicare has no cap
- Self-employed pay 15.3% (both employer and employee portions) but deduct 50% from AGI
- For most lower and middle-income workers, FICA exceeds their federal income tax
- FICA contributions earn Social Security credits — 40 credits (10 years of work) required for full retirement benefits
- The Additional Medicare Tax of 0.9% applies to wages and SE income above $200K (single) / $250K (MFJ)
Frequently Asked Questions
Q: Can I avoid paying FICA? A: For most workers, no. FICA is mandatory for all wage earners and self-employed individuals. Some narrow exemptions exist for students, certain visa holders, and specific religious workers who formally opt out.
Q: Does FICA apply to retirement income? A: No. Wages from employment trigger FICA; Social Security benefits, pension income, and investment income (dividends, capital gains, interest) do not.
Q: Is FICA included in the federal income tax withholding line on my paystub? A: No. FICA appears as separate line items on your paystub: "Social Security Tax" and "Medicare Tax." Federal income tax withholding is separate.
