Social Security & Medicare Taxes: What Every Worker Needs to Know (2026)
Two lines on your pay stub — Social Security and Medicare — may seem small individually, but together they represent 7.65% of every dollar you earn (up to a cap). For a $70,000/year worker, that's over $5,355 per year. Yet most workers have only a vague understanding of what these taxes are, where they go, and what they get in return. This guide covers everything you need to know for 2026.
What Are FICA Taxes?
FICA stands for the Federal Insurance Contributions Act. It encompasses two separate taxes that fund two distinct federal programs:
- Social Security (OASDI): Funds retirement benefits, disability insurance (SSDI), and survivor benefits for eligible workers and their families.
- Medicare (HI): Funds hospital insurance (Medicare Part A) for Americans aged 65 and over, and certain disabled individuals.
Unlike federal income tax, FICA taxes are not progressive. Everyone with wages — from a part-time minimum-wage worker to a six-figure executive — pays the same flat percentage up to the respective caps.
2026 FICA Rates at a Glance
| Tax | Employee Rate | Employer Match | Wage Cap |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | $176,100 |
| Medicare | 1.45% | 1.45% | No cap |
| Additional Medicare Tax | 0.9% | None | Over $200,000 (single) |
| Total Employee FICA | 7.65% | 7.65% | Up to SS cap |
Social Security Tax: The Wage Base Explained
Social Security tax applies only to wages up to the 2026 wage base of $176,100. Once your cumulative wages for the year exceed this threshold, Social Security withholding stops completely for the remainder of the year. This means high earners experience a jump in their net take-home pay mid-year when the cap is hit.
For a worker earning $200,000, they pay Social Security tax on the first $176,100 of wages — a total employee contribution of $10,918.20. The remaining $23,900 of wages is exempt from Social Security tax entirely.
Medicare Tax: No Cap and the Surcharge
Unlike Social Security, Medicare tax applies to all wages with no upper limit. In addition, the Affordable Care Act added the Additional Medicare Tax (AMT) of 0.9% on wages above certain thresholds:
- $200,000 for single filers and married filing separately
- $250,000 for married filing jointly
- $125,000 for married filing separately
Your employer is required to withhold the extra 0.9% once your individual wages from that employer exceed $200,000 in the year — but they don't know your total household income. If you and your spouse together exceed $250,000 but individually neither does, you'll owe the surcharge at tax time rather than through withholding.
Self-Employed Workers Pay More
If you're self-employed, you pay both the employee and employer share of FICA — called the Self-Employment (SE) tax. That means:
- 12.4% for Social Security (on net self-employment earnings up to $176,100)
- 2.9% for Medicare (on all net self-employment earnings)
- 0.9% Additional Medicare Tax if earnings exceed $200,000
The combined SE tax rate is 15.3% on the first $176,100 of net earnings. However, you can deduct half of the SE tax as an above-the-line adjustment on your federal income tax return, which partially offsets the extra burden.
What Do You Get in Return?
FICA taxes are not just taken — they earn you benefits. Your Social Security contributions are tracked throughout your working life to calculate your eventual retirement benefit. The more you earn (up to the wage base), and the longer you work, the higher your monthly Social Security check at retirement.
You need at least 40 "credits" (roughly 10 years of work with sufficient earnings) to be eligible for retirement benefits. Medicare Part A — hospital coverage — is free at age 65 for anyone with 40+ quarters of work history, funded by the Medicare portion of your FICA taxes.
Your annual FICA burden by income level
The table below shows total employee FICA deductions at different income levels for 2026. Note how the effective FICA rate declines above the Social Security wage base because the 6.2% SS tax stops at $176,100:
| Annual Income | Social Security Tax | Medicare Tax | Total FICA | Effective FICA Rate |
|---|---|---|---|---|
| $30,000 | $1,860 | $435 | $2,295 | 7.65% |
| $60,000 | $3,720 | $870 | $4,590 | 7.65% |
| $100,000 | $6,200 | $1,450 | $7,650 | 7.65% |
| $176,100 (cap) | $10,918 | $2,553 | $13,471 | 7.65% |
| $200,000 | $10,918 | $2,900 | $13,818 | 6.91% |
| $250,000 | $10,918 | $3,625 + $450* | $14,993 | 6.00% |
*The $450 represents the Additional Medicare Tax (0.9% on wages over $200,000 single). Your employer does not match this surcharge — it is an employee-only tax.
How your Social Security benefit is calculated
Your future monthly Social Security retirement benefit is not simply a percentage of your final salary. It's calculated using a complex formula based on your lifetime earnings history:
- The SSA indexes your earnings. Each year of earnings is adjusted for wage inflation to bring past wages into today's dollars. The SSA uses up to 35 years of indexed earnings.
- They calculate your AIME. Your Average Indexed Monthly Earnings (AIME) is your indexed lifetime earnings divided by the number of months in your highest 35 earning years (420 months). If you worked fewer than 35 years, zeros are averaged in — each additional year of work replaces a zero and increases your benefit.
- They apply the PIA formula (bend points). Your Primary Insurance Amount (PIA) is calculated by applying three rates to portions of your AIME: 90% of the first $1,226 of AIME, plus 32% of AIME between $1,226 and $7,391, plus 15% of AIME above $7,391. These percentages deliberately favor lower earners.
The bend-point formula means low-income workers get back a much higher percentage of their pre-retirement earnings than high earners. A worker earning $30,000/year replaces roughly 50–60% of their pre-retirement income; a worker earning $150,000/year replaces only 25–35%.
When to claim Social Security: the break-even analysis
You can claim Social Security as early as age 62, at full retirement age (FRA), or as late as age 70. Each option has a different monthly benefit:
| Claiming Age | Benefit vs. FRA (born 1960+, FRA = 67) | Break-Even vs. Waiting to 67 |
|---|---|---|
| Age 62 (earliest) | −30% (reduced permanently) | Break-even vs. FRA ≈ age 78 |
| Age 64 | −20% | Break-even vs. FRA ≈ age 79 |
| Age 67 (FRA) | 100% (full benefit) | Baseline |
| Age 68 | +8% per year delayed credit | Larger benefit for life |
| Age 70 (maximum) | +24% above FRA | Break-even vs. FRA ≈ age 82–83 |
The decision comes down to life expectancy and financial need. If you're in excellent health with a family history of longevity, delaying to 70 typically maximizes lifetime benefits. If you're in poor health or need income immediately, claiming early makes mathematical sense. Married couples should also consider the higher earner delaying to 70 to maximize the surviving spouse's benefit.
Who is exempt from FICA?
Not every worker pays FICA taxes. Several groups have partial or full exemptions:
- Certain government employees: Some state and local government workers hired before 1984 may participate in an alternative public pension system and be exempt from Social Security tax. However, they still pay Medicare tax.
- Nonresident aliens on specific visas: F-1, J-1, M-1, and Q visas for students, teachers, and exchange visitors are generally exempt from FICA for a limited period (typically 5 years for F-1 students).
- Religious order members: Members of qualifying religious orders who have taken a vow of poverty are exempt from FICA taxes.
- Certain student workers: Students employed by their own school may be exempt from FICA while enrolled at least half-time and performing work related to their education program.
- Railroad workers: Railroad employees pay into the Railroad Retirement System (RRS) instead of Social Security, though the benefit structure is similar.
If you believe you may qualify for an exemption and FICA is being withheld, speak with your employer's payroll department and consult IRS Publication 517 (for religious workers) or Publication 519 (for foreign nationals).
Frequently asked questions
Is the Social Security wage base the same every year?
No — the Social Security Administration adjusts the wage base annually based on changes in national average wages. In 2024 it was $168,600, in 2025 it was $176,100, and it will continue to rise in future years. The Medicare tax has no wage base and applies to all earned income without limit.
Do I get Social Security credit for years I paid FICA but don't have 40 quarters?
Yes — your earnings are recorded even if you don't yet have the 40 credits required for retirement benefits. If you stop working before reaching 40 credits, those credits remain on your record permanently. You may also be eligible for benefits as a spouse (if your spouse has 40 credits) without having your own 40 credits.
Can I reduce or avoid FICA taxes legally?
For employees, there is no legal way to avoid FICA. However, for self-employed workers, certain business structuring strategies (like paying yourself a reasonable salary through an S-Corp) can legally reduce the amount of income subject to SE tax compared to a sole proprietorship. This is a complex area requiring guidance from a CPA familiar with self-employment tax planning.
