FICA on Your First Paycheck: Social Security and Medicare Explained

By GetTaxCalculator Editorial Team· Published 2026-09-12

FICA stands for Federal Insurance Contributions Act. It is the 7.7% combined tax that funds Social Security (6.2%) and Medicare (1.5%). Unlike federal income tax, FICA has no standard deduction and no brackets for most workers - it applies to every dollar you earn from your first paycheck. On a $500 weekly paycheck, you will see $38.25 withheld for FICA before you receive a cent.

What Social Security and Medicare fund

FICA contributions split between two separate trust funds with distinct purposes:

Social Security (6.2%) - formally called OASDI (Old Age, Survivors, and Disability Insurance) - funds three programs:

Retirement benefits: Monthly payments to workers who have reached retirement age and paid into the system for at least 10 years (40 quarters).
Disability benefits (SSDI): Monthly payments to workers who become disabled and cannot work, subject to work history requirements.
Survivors benefits: Monthly payments to spouses, children, and other dependents of deceased workers who paid into the system.

Medicare (1.45%) funds federal health insurance for people age 65 and older and certain younger people with disabilities. Working and paying Medicare tax for at least 10 years makes you eligible for Medicare Part A (hospital insurance) at no premium when you reach 65.

The rates for 2026

For 2026, the FICA rates are:

Social Security: 6.2% on wages up to $184,500. Wages above $184,500 are not subject to Social Security tax (no Social Security tax on the excess).
Medicare: 1.5% on all wages with no upper limit. Every dollar of wages above the Social Security wage base still has Medicare tax applied.
Additional Medicare: 0.9% on wages above $200,000 (single filers, $250,000 for married filing jointly). This extra rate has no employer match.
Combined employee FICA rate: 7.7% (for most workers earning below $$184,500).

These rates have been stable for decades. The Social Security wage base adjusts annually with wage inflation; the Medicare rate and the Additional Medicare threshold are set by statute and do not automatically adjust for inflation.

Your employer's matching contribution

Your pay stub shows only the employee share of FICA. But your employer pays an equal amount on your behalf, on top of your salary:

Employee Social Security: 6.2%
Employer Social Security: 6.2% (matched)
Employee Medicare: 1.5%
Employer Medicare: 1.5% (matched)
Total FICA going to the government on your wages: 15.3%

The employer match does not come from your paycheck - it is an additional payroll cost your employer pays on top of your wages. If you earn $50,000, your employer's total cost of employing you is approximately $53,825 after the employer FICA match (plus any benefits).

The exception is the Additional Medicare Tax (0.9%) on high-income wages - that portion has no employer match. It is paid entirely by the employee.

Why FICA cannot be avoided

Federal income tax can be reduced to zero through deductions, credits, and low enough income. FICA cannot. Here is why:

No standard deduction applies to FICA: The $16,100 standard deduction reduces your federal income tax. It has no effect on FICA. FICA is calculated on gross wages, not taxable income.
No brackets: FICA is a flat percentage. Unlike income tax, there is no 0% rate at the bottom. Your first dollar of wages triggers FICA at the full rate.
No credits reduce FICA: The Child Tax Credit, EITC, education credits, and other income tax credits do not reduce FICA. They reduce income tax only.
Mandatory by law: FICA withholding is required by the Federal Insurance Contributions Act. Your employer is legally required to withhold it. Unlike voluntary deductions (health insurance, 401(k)), you cannot opt out.

The only way to pay less FICA is to earn less (or qualify for one of the narrow exemptions covered below).

Worked example: $500 weekly paycheck

Here is exactly what happens to a $500 weekly paycheck under 2026 FICA rates:

Gross pay: $500.00
Social Security (6.2%): $500 x 0.062 = $31.00
Medicare (1.5%): $500 x 0.0145 = $7.25
Total FICA withheld: $38.25

After FICA (before federal income tax, state tax, and other deductions):

$500.00 - $38.25 = $461.75

Over a full year at $500 per week (52 weeks), total wages would be $26,000. Total annual FICA withheld would be:

Social Security: $26,000 x 0.062 = $1,612.00
Medicare: $26,000 x 0.0145 = $377.00
Total annual FICA: $1,989.00

Your employer would also pay an additional $1,989.00 in employer FICA on your behalf.

Who is exempt from FICA

A small number of workers are exempt from some or all FICA contributions:

Students working for their own university: Under IRC Section 3121(b)(10), students enrolled at least half-time who work for the school they attend are exempt from FICA on those specific wages. This covers campus jobs, teaching assistants, and research assistants at their own university.
Certain government employees: Some state and local government employees covered by a qualifying public pension system may be exempt from Social Security (but not Medicare). This varies by state and employer.
Qualifying religious workers: Members of certain religious orders who have taken a vow of poverty, and some clergy, may be exempt under specific IRS rules.
Nonresident aliens in certain visa categories: Some F-1, J-1, M-1, and Q-1 visa holders are exempt from FICA, subject to rules on length of U.S. presence and the type of work performed.

These exemptions are narrow and have specific requirements. If you believe you qualify, your employer's payroll department can confirm whether the exemption applies to your situation.

Frequently Asked Questions

What does FICA stand for?

FICA stands for Federal Insurance Contributions Act. It is the federal law that authorizes the withholding of Social Security and Medicare taxes from wages. The law has been in place since 1935 (Social Security) and 1965 (Medicare).

What is the Social Security wage base in 2026?

In 2026, Social Security tax (6.2%) applies only to the first $184,500 of wages. Earnings above $184,500 are not subject to the 6.2% Social Security rate, though all earnings (including those above the wage base) remain subject to Medicare tax.

Does my employer pay FICA too?

Yes. For every dollar you pay in FICA, your employer pays an equal amount. Your 7.7% employee FICA is matched by another 7.7% from your employer, for a total of 15.3% going into the FICA system on your behalf. You do not see the employer share on your pay stub - it is paid separately.

Can I opt out of FICA?

Most private-sector employees cannot opt out of FICA. The contributions are mandatory by law. The primary exceptions are certain government employees covered by a qualifying public pension, some religious workers, and students working for their own university while enrolled at least half-time.

What is the Additional Medicare Tax?

High-income earners pay an extra 0.9% Medicare surtax on wages above $200,000 (single filers). This was added by the Affordable Care Act and has no employer match - the additional 0.9% is paid entirely by the employee.

Is FICA the same as Social Security tax?

FICA includes both Social Security tax and Medicare tax. When people say 'Social Security tax,' they typically mean the 6.2% component of FICA. Medicare tax (1.45%) is the other component. Together they make up the 7.65% FICA rate most employees pay.

Will FICA contributions affect my future benefits?

Yes. Social Security contributions are tracked under your Social Security number. The more you contribute over your working life (up to the annual wage base), the higher your eventual Social Security retirement and disability benefit will be. Medicare contributions similarly establish your eligibility for Medicare at age 65.
