Most Americans focus on federal income tax when they look at their paycheck — but FICA is often the larger deduction for middle-income earners. A single filer earning $60,000 pays roughly $4,590 in FICA versus $4,858 in federal income tax. Understanding what FICA is, where it goes, and how self-employment changes the math is essential for accurate financial planning.
What FICA Is and What It Funds
FICA stands for the Federal Insurance Contributions Act. It funds two federal programs:
Social Security (OASDI — Old Age, Survivors, and Disability Insurance):
- Retirement income for workers 62+
- Disability benefits for workers who become unable to work
- Survivor benefits for spouses and children of deceased workers
- The average monthly retirement benefit in 2026 is approximately $1,980
Medicare:
- Part A: Inpatient hospital coverage (premium-free for most people who paid FICA for 10+ years)
- Part B and D: Outpatient care and prescription drugs (separately funded by premiums, but FICA taxes contribute to the Part A trust fund)
Unlike federal income tax, FICA is not progressive. It applies at a flat rate from the first dollar of wages.
2026 FICA Rates
| Tax | Employee Rate | Employer Rate | Combined Rate |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% |
| Medicare | 1.45% | 1.45% | 2.9% |
| Total FICA | 7.65% | 7.65% | 15.3% |
Your employer matches your 7.65% — the full 15.3% is the actual cost of your employment. This employer share is not visible on your pay stub, but it affects total compensation negotiations at many companies.
Dollar impact at common salary levels:
| Gross Salary | Annual Employee FICA | Monthly Deduction |
|---|---|---|
| $50,000 | $3,825 | $319 |
| $75,000 | $5,738 | $478 |
| $100,000 | $7,650 | $638 |
| $150,000 | $11,475 | $956 |
| $200,000 | $13,818 | $1,152 |
Note that $200,000 is higher than the Social Security wage base — see the next section for why the FICA bill plateaus above that threshold.
Social Security Wage Base: The $176,100 Cap
Social Security tax only applies to wages up to the wage base limit — $176,100 in 2026 (adjusted annually for the National Average Wage Index). Income above this amount is exempt from the 6.2% Social Security portion, though Medicare continues with no cap.
Example — $220,000 salary:
- Social Security: 6.2% × $176,100 = $10,918 (on the first $176,100 only)
- Medicare: 1.45% × $220,000 = $3,190 (on all wages)
- Total employee FICA: $14,108
The wage base cap makes the Social Security portion of FICA regressive: a worker earning $176,100 and a worker earning $500,000 pay the same nominal Social Security tax ($10,918), making it a smaller percentage of the higher earner's income.
Additional Medicare Tax on High Earners
Since 2013, the Affordable Care Act imposes an extra 0.9% Medicare surtax on wages above:
- $200,000 (single, head of household, married filing separately)
- $250,000 (married filing jointly)
This additional 0.9% is employee-only — the employer does not match it. Employers withhold it automatically once your wages from that employer exceed $200,000, regardless of filing status.
Example — $280,000 single filer:
- Social Security: 6.2% × $176,100 = $10,918
- Medicare (standard): 1.45% × $280,000 = $4,060
- Additional Medicare: 0.9% × ($280,000 − $200,000) = $720
- Total employee FICA: $15,698
If you have multiple jobs and no single employer pays you over $200,000, none will withhold the surtax. You will owe it when you file — use Form 8959 to calculate and pay it.
Multiple Jobs: Social Security Overpayment
If you work two jobs simultaneously, each employer withholds Social Security independently. If your combined wages exceed $176,100, you will have over-withheld Social Security tax. The IRS automatically refunds the excess when you file — it appears as a credit on Form 1040. You do not need to request it separately.
Example: Two jobs at $100,000 each = $200,000 total wages. Each employer withholds 6.2% × $100,000 = $6,200, for a combined $12,400 withheld. The correct amount is 6.2% × $176,100 = $10,918. The $1,482 overpayment is refunded via your tax return.
Self-Employed: You Pay Both Sides
When you are self-employed (sole proprietor, single-member LLC, freelancer), there is no employer to split FICA with. You owe the full 15.3% self-employment (SE) tax on net self-employment income up to the wage base, plus 2.9% Medicare above.
Self-employed freelancer, $90,000 net income:
| Component | Calculation | Amount |
|---|---|---|
| Net SE income | $90,000 | — |
| SE tax base (×92.35%) | $90,000 × 0.9235 | $83,115 |
| Social Security (12.4%) | $83,115 × 12.4% | $10,306 |
| Medicare (2.9%) | $83,115 × 2.9% | $2,410 |
| Total SE tax | $12,716 | |
| Deductible half | $12,716 ÷ 2 | −$6,358 (reduces federal AGI) |
The 92.35% multiplier (100% − 7.65%) exists to approximate the employer deduction — a technical adjustment so self-employed filers aren't double-taxed on the employer-equivalent portion.
Self-employment tax is paid quarterly via estimated tax payments. Use our Self-Employed Tax Calculator to compute your SE tax, the deductible half, and your quarterly payment amounts.
How to Reduce FICA as Self-Employed
The most effective strategy: elect S-Corp status for your LLC or corporation once net profit consistently exceeds ~$60,000–$80,000.
An S-Corp pays you a "reasonable salary" (subject to FICA on that amount), then distributes additional profit as dividends — which are not subject to FICA. If you earn $150,000 net and pay yourself an $80,000 salary, only the $80,000 is subject to the 15.3% SE rate. The $70,000 distribution avoids it entirely, saving approximately $9,800 in SE tax annually (minus accounting costs of ~$1,500–$3,000/year for S-Corp compliance).
FICA vs. Federal Income Tax: Key Differences
| Feature | FICA | Federal Income Tax |
|---|---|---|
| Rate structure | Flat (7.65% employee) | Progressive (10%–37%) |
| Applies to | Wages and SE income only | Wages, investments, all income |
| Deductions reduce it? | No — deductions do not lower FICA | Yes — 401(k), HSA, standard deduction all reduce it |
| Wage cap | $176,100 (SS portion only) | None |
| Self-employed rate | 15.3% on SE income | Same as employee |
The practical implication: contributing to a traditional 401(k) reduces your federal income tax but does not reduce FICA. Only specific pre-tax arrangements (like Section 125 cafeteria plans for health insurance) reduce FICA.
