FICA taxes fund Social Security and Medicare, and they come out of nearly every American paycheck. For 2026, you pay 6.2% for Social Security (up to a wage cap) and 1.45% for Medicare, plus a possible extra 0.9% Medicare tax if you earn above certain thresholds. Together, these payroll taxes explained add up to a significant slice of your gross pay—often 7.65% or more—but most workers don't know exactly what they're for or how they're calculated.

You've probably noticed "FICA" on your paystub and wondered whether it's another name for income tax, or why the amount changes if your salary goes up. The answer is simpler than tax forms make it sound. FICA is a dedicated payroll tax that funds two specific programs: Social Security, which pays retirement and disability benefits, and Medicare, which covers hospital and medical insurance. Your employer matches what you pay (that's the other 7.65% you don't see), and together those dollars fund benefits for current retirees and disabled workers. Unlike federal income tax, which depends on your filing status and deductions, FICA is a flat rate on nearly every dollar you earn—until you hit the wage cap. Understanding how much FICA withheld from each paycheck helps you build a realistic budget and see where your money actually goes. Use our paycheck calculator to plug in your own salary and see your FICA liability in real time.

What Is FICA and Why It Matters

FICA stands for the Federal Insurance Contributions Act, the 1935 law that established Social Security and expanded to include Medicare in 1965. The name "FICA tax" is used loosely to describe the payroll taxes withheld for both programs combined. When you see "FICA" on your paystub, it represents two separate taxes: OASDI (Old-Age, Survivors, and Disability Insurance—the formal name for the Social Security portion) and HI (Hospital Insurance—Medicare Part A). Both are withheld automatically from your paycheck, and your employer is required to contribute a matching amount.

Why it matters: FICA taxes are not optional or income-based like federal or state income tax. You pay them on wages, salaries, and tips the moment you earn them, regardless of how much money you make overall. Because they're withheld before federal income tax, they reduce your take-home pay even in months when you might get a federal refund. Unlike federal tax, you cannot reduce your FICA liability by claiming deductions or adjusting your filing status. For most workers, FICA represents 7.65% of gross pay (6.2% Social Security + 1.45% Medicare), which often exceeds state income tax or federal income tax in lower-to-middle income brackets.

The other critical fact: FICA is a payroll tax, not a wealth tax. Only income from wages, salaries, self-employment, and certain other earned income is subject to FICA. Investment income, capital gains, rental income, and most business income not classified as wages escape FICA altogether—a major reason why high-income households often pay a lower effective FICA rate than middle-class workers.

Social Security Tax: 6.2% of Your Paycheck

The Social Security portion of FICA is 6.2% of your wages, withheld from every paycheck. This social security tax rate 2026 has been fixed at 6.2% since 1990 and does not change year to year. The 6.2% is paired with an employer match (another 6.2%), so the total Social Security tax is 12.4%—half paid by you, half by your employer (or, if you're self-employed, both halves paid by you).

Where the 6.2% limit kicks in: Social Security tax is capped at the social security wage base, which is the maximum annual salary subject to the tax. For 2026, the wage base is $184,500. If you earn $184,500 or more, you pay 6.2% on the first $184,500 only; earnings above that cap are exempt from Social Security tax. If you earn $150,000, you pay 6.2% on the full $150,000. If you earn $200,000, you pay 6.2% on $184,500 and nothing on the remaining $15,500.

Here's why this cap exists: Social Security benefits are tied to your earnings history, and the program is designed as a wage-replacement system capped at a maximum monthly benefit. Very high earners pay proportionally less Social Security tax on their total income because the wage base limit stops the withholding. A person earning $300,000 pays 6.2% on $184,500 (total $11,439 per year), while the 6.2% appears to be "only" 3.81% of their total income. A person earning $100,000 pays 6.2% on all $100,000 (total $6,200), which is exactly 6.2% of their income.

Concrete example: You earn $190,000 in 2026. Social Security tax is calculated as: $184,500 × 0.062 = $11,439. Your employer also contributes $11,439. You do not pay Social Security tax on the remaining $5,500, and neither does your employer.

Medicare Tax: 1.45% Plus a Potential Bonus Tax

The Medicare portion of FICA is 1.45%, withheld on all wages with no upper limit. Unlike Social Security, there is no wage base cap for the standard medicare tax rate 2026—you pay 1.45% on every dollar you earn, even if you make $1 million. The 1.45% is split: you pay 1.45%, and your employer matches 1.45%, for a combined total of 2.9%.

However, there's a second layer. If your income exceeds certain thresholds, you owe an additional medicare tax threshold of 0.9%—an extra Medicare tax introduced in 2013 under the Affordable Care Act. This additional medicare tax applies to wages above $200,000 (if single), $250,000 (if married filing jointly), or $125,000 (if married filing separately). Unlike the employer-matched portion of the standard 1.45%, the additional 0.9% is paid by the employee only; employers do not match it.

How the additional Medicare tax works: If you're single and earn $225,000 in 2026, your Medicare tax liability is:

Standard Medicare tax: $225,000 × 1.45% = $3,262.50
Additional Medicare tax: ($225,000 − $200,000) × 0.9% = $225
Total Medicare tax: $3,487.50

Note that the additional Medicare tax is calculated on wages alone, not on investment income or self-employment income (though self-employed individuals do owe it on net self-employment earnings above the same thresholds).

Concrete example: You earn $95,000 in 2026 and are single. You pay 1.45% Medicare tax on all $95,000 (= $1,377.50) but no additional Medicare tax because you're below the $200,000 threshold.

Another scenario: You earn $210,000, single. You pay 1.45% on all $210,000 (= $3,045), plus 0.9% on the $10,000 above $200,000 (= $90), for a total of $3,135 in Medicare tax.

The FICA Wage Base Limit and How It Works

The FICA wage base limit 2026 applies only to Social Security (6.2%), not to Medicare. For 2026, the social security wage base is $184,500. This ceiling is adjusted every year based on the National Average Wage Index; it typically rises 2–4% annually to account for inflation and wage growth.

Understanding the wage base is crucial because it creates a significant tax cliff for high earners. A person earning exactly $184,500 pays 6.2% on the full amount; a person earning $184,501 pays 6.2% on only $184,500, effectively paying a lower rate on that extra dollar. This is not a problem unique to Social Security—many benefit programs have similar cliffs—but it does mean that the fica tax rate is not truly uniform across all income levels.

Why the cap exists: Social Security is a benefits program, not a general revenue tax. The benefit formula is designed to replace roughly 40% of pre-retirement earnings for an average worker, with a maximum monthly benefit. Because very high earners cannot receive proportionally higher benefits, the program does not require them to pay tax on all earnings. This design choice makes Social Security more progressive in effect—lower earners pay a larger share of their retirement income from Social Security, while higher earners are expected to fund more retirement via private savings.

Who should track this: If you're self-employed, a high earner, or working multiple jobs, monitor your year-to-date wages to ensure you don't overpay Social Security tax. If you have two jobs and each employer withholds 6.2% independently, and your combined earnings exceed the wage base, you may over-withhold and need to claim a credit when you file your tax return. The IRS allows you to claim the excess as a refundable credit (on Form 1040, Schedule 2).

How FICA Is Calculated on Your Paycheck

FICA calculation formula is straightforward: multiply your gross wages for the pay period by the applicable rates. For most employees in 2026:

Social Security FICA = (Gross wages, up to $184,500 for the year) × 6.2% Medicare FICA = Gross wages × 1.45% Additional Medicare FICA = (Gross wages above $200,000/$250,000/$125,000, depending on filing status) × 0.9%

Your employer or payroll processor handles the calculation and displays the withholding on your paystub. Each pay period, the system checks your year-to-date earnings. Once you've earned $184,500 in a calendar year, Social Security withholding stops; Medicare withholding continues through year-end.

Step-by-step example for a biweekly paycheck:

Gross pay: $3,500
Social Security: $3,500 × 0.062 = $217
Medicare: $3,500 × 0.0145 = $50.75
Additional Medicare (if applicable, based on year-to-date): $0 (in most cases)
Total FICA withheld: $267.75

Your employer then withholds an additional $267.75 (the employer match) from company funds and sends both amounts to the IRS on your behalf.

The IRS requires employers to deposit FICA taxes (and federal income tax) either weekly or biweekly, depending on the amount owed. These deposits are tracked separately from income tax deposits and are reported on Form 941 (Employer's Quarterly Federal Tax Return), which all employers file quarterly.

FICA for Self-Employed Workers and Contractors

Self-employed workers and independent contractors do not have an employer to match their FICA contributions. Instead, they pay both the employee and employer portions of Social Security and Medicare—a combined 15.3%—through self-employment tax. This is self-employment tax vs FICA in practical terms: FICA is withheld from employee wages by an employer, while self-employment tax is calculated and paid by a self-employed individual on Form Schedule SE.

For 2026, self-employment tax rate is 15.3%: 12.4% for Social Security (same $184,500 wage base limit) and 2.9% for Medicare (no limit), plus the 0.9% additional Medicare tax if net earnings exceed the thresholds. A self-employed person earning $100,000 in net business income pays approximately $15,300 in self-employment tax, versus a W-2 employee earning $100,000 who pays only $7,650 in FICA (with the employer matching the other $7,650).

However, self-employed individuals get a small deduction: they can deduct half of their self-employment tax as a business expense on their Form 1040. If you owe $15,300 in self-employment tax, you can deduct $7,650 from your adjusted gross income, which reduces your federal income tax. This is not a full offset—self-employment tax is still substantially higher—but it does reduce the hit slightly.

Important note: Self-employed individuals are responsible for paying self-employment tax in full when they file their annual return, or via quarterly estimated tax payments (Form 1040-ES). Unlike employees, there is no withholding throughout the year, so many self-employed workers must budget for a large tax bill in April (or pay quarterly to avoid penalties).

How Much FICA You'll Pay on Different Salaries

The table below shows the annual FICA tax liability for various salary levels in 2026, assuming you're single (or married filing separately below the Medicare threshold) and have no self-employment income.

| Annual Salary | Social Security (6.2%) | Medicare (1.45%) | Additional Medicare (0.9%) | Total FICA | |---|---|---|---|---| | $50,000 | $3,100 | $725 | $0 | $3,825 | | $100,000 | $6,200 | $1,450 | $0 | $7,650 | | $150,000 | $9,300 | $2,175 | $0 | $11,475 | | $184,500 | $11,439 | $2,675 | $0 | $14,114 | | $200,000 | $11,439 | $2,900 | $0 | $14,339 | | $250,000 | $11,439 | $3,625 | $450 | $15,514 | | $300,000 | $11,439 | $4,350 | $900 | $16,689 |

Key observations:

Below $184,500: FICA is a straight 7.65% (6.2% + 1.45%)
Between $184,500 and $200,000: Social Security stops, so each extra dollar is taxed only 1.45% for Medicare
Above $200,000 (single): the additional 0.9% Medicare tax begins, but the effective FICA rate still decreases overall because Social Security is capped

Why FICA matters more than it looks: FICA is often overlooked because it's withheld automatically, but it's a large portion of payroll taxes. For a $100,000 salary, FICA totals $7,650 before federal and state income taxes are even calculated. This means your take-home pay is significantly reduced before you see any of it. A worker earning $100,000 might take home $65,000–$72,000 depending on state, filing status, and deductions—FICA alone accounts for over 7% of that reduction.

Why FICA on Every Paycheck

Every paycheck withholds FICA because the Social Security and Medicare systems are funded on a pay-as-you-go basis. Payroll taxes collected today pay benefits for current retirees and disabled workers, not just for your own future benefits. This is why FICA withholding is non-optional and uniform—it's a mandatory insurance contribution, not a tax deferred into an investment account.

Congress set the FICA rates (6.2% and 1.45%) based on actuarial projections of the programs' costs. Social Security trustees adjust the wage base annually to keep the program solvent. Medicare's funding is more complex—Part A (hospital insurance) is funded primarily by the 2.9% Medicare tax (plus the additional 0.9% above the income threshold), while Parts B and D (doctor and drug coverage) are funded partly by beneficiary premiums and general Treasury revenue.

The reason FICA hits every paycheck, even for people who are far from retirement, is to maintain a continuous revenue stream. If withholding were optional or sporadic, the system would become insolvent. This is also why FICA is sometimes described as regressive: lower-income workers pay a larger share of their income in FICA than higher earners do (because of the Social Security wage base cap), and they have less ability to supplement their eventual benefits with savings or investment income.

Understanding why fica on every paycheck helps you plan. You cannot avoid FICA if you're earning wages. You can reduce it slightly through pre-tax deductions (like traditional 401(k) contributions reduce the gross amount subject to tax, but not FICA), but in most cases, FICA is a fixed cost of employment.

The Bottom Line

FICA taxes—6.2% for Social Security, 1.45% for Medicare, plus a potential 0.9% additional Medicare tax—are withheld from nearly every paycheck and add up to a significant portion of your total tax burden. The social security wage base of $184,500 limits how much Social Security tax you pay, while Medicare tax has no ceiling. Self-employed workers pay both the employee and employer portions (15.3% total), while W-2 employees split the cost with their employer. On a $100,000 salary, FICA totals $7,650 per year—roughly 7.65% of your gross pay—before any federal or state income tax is withheld.

The key takeaway is that FICA is not optional, not deductible, and not based on how much you owe at tax time. It's a dedicated payroll tax that funds specific benefits (Social Security retirement and disability, Medicare hospital insurance). Every dollar withheld is tied to your benefit eligibility, but the link is not one-to-one—very high earners pay a lower effective rate due to the Social Security cap.

Frequently Asked Questions About FICA Taxes and Medicare

What is FICA and why do I pay it? FICA (Federal Insurance Contributions Act) funds Social Security and Medicare. You pay it on wages to support current retirees, disabled workers, and yourself when you become eligible. FICA is withheld automatically and is not optional, even if you owe no federal income tax.

What is the FICA tax rate for 2026? The employee FICA rate for 2026 is 7.65%: 6.2% for Social Security and 1.45% for Medicare. If you earn above $200,000 (single) or $250,000 (married filing jointly), you also owe an additional 0.9% Medicare tax, raising your total to 8.55%. Your employer matches the first 7.65% (but not the additional 0.9%).

Does FICA have a wage base limit? Social Security FICA has a FICA wage base limit 2026 of $184,500. Medicare FICA has no limit and applies to all wages. Once you earn $184,500, you stop paying 6.2% Social Security tax for the remainder of the year, but you continue paying Medicare tax on every dollar.

How is FICA calculated on my paycheck? Multiply your gross wages by the applicable rates: 6.2% for Social Security (up to the annual wage base) and 1.45% for Medicare (on all wages). If you're above the additional Medicare tax threshold ($200,000 single, $250,000 married filing jointly), also multiply the excess by 0.9%. Your employer or payroll provider handles this calculation and displays it on your paystub.

What is OASDI tax? OASDI stands for Old-Age, Survivors, and Disability Insurance—the formal name for the Social Security portion of FICA. The 6.2% withheld for Social Security is sometimes labeled "OASDI tax" on paystubs. It funds retirement benefits, survivor benefits for deceased workers' families, and disability benefits.

What does HI mean on my paystub? HI stands for Hospital Insurance, which is Medicare Part A. The 1.45% Medicare tax withheld from your paycheck funds HI. This is separate from Medicare Parts B (doctor services) and D (drug coverage), which are funded by different revenue sources and beneficiary premiums.

Why is Social Security tax capped but Medicare is not? Social Security is a benefits program with a maximum benefit amount; very high earners cannot receive proportionally higher benefits, so the program does not require tax on all earnings. Medicare is designed as a universal health insurance program with no benefit cap, so the tax applies to all wages. The additional 0.9% Medicare tax was added in 2013 to help fund the Affordable Care Act and applies only to high earners.

What happens if I work two jobs and exceed the wage base? If your combined earnings from two employers exceed $184,500, you may over-pay Social Security tax. You can claim the excess as a refundable credit on your Form 1040 (line 24c, Schedule 2) when you file your annual return. Only one employer withholds correctly; the other over-withholds because each employer calculates independently.

Do self-employed people pay more FICA than W-2 employees? Self-employed workers pay both the employee and employer portions of FICA—15.3% total—versus 7.65% for a W-2 employee (whose employer matches the other 7.65%). However, self-employed individuals can deduct half their self-employment tax as a business expense, which lowers their taxable income slightly. They still pay substantially more in total FICA.

Can I reduce my FICA tax? Mostly no. A traditional 401(k), 403(b), or similar plan lowers your income-tax bill, but not your FICA — Social Security and Medicare are still withheld on those contributions. The pre-tax accounts that do reduce FICA are the ones run through an employer cafeteria plan: HSA, health FSA, dependent care FSA, and health-insurance premiums. For 2026, you can contribute up to $24,500 (or $32,500 with catch-up if age 50+) to a 401(k) for the income-tax break.

Is FICA the same as payroll tax? FICA is the largest component of payroll taxes. Payroll taxes include FICA (Social Security and Medicare), federal income tax withholding, and state/local income tax. FICA is sometimes called "FICA payroll tax" to distinguish it from income tax withholding, even though both are withheld from paychecks.
