Key Takeaways:
FICA is a mandatory federal payroll tax that funds Social Security and Medicare. Employees pay 7.65%, employers match 7.65%, and self-employed workers pay 15.3% under SECA.
The Social Security wage base is $184,500 in 2026, which caps the maximum employee Social Security withholding at $11,439.
The additional 0.9% Medicare tax applies to wages above your filing-status threshold, and there’s no employer match for it.
You may notice several deductions on your paycheck, such as federal income tax, state taxes, and Social Security. The Federal Insurance Contributions Act (FICA) tax is a critical component of these deductions. While the FICA tax may appear complex at first, understanding its purpose and ramifications can help you make sound financial decisions. This blog post will go into detail on the FICA tax, its components, and how it affects your salary.
What is FICA Tax?
FICA stands for the Federal Insurance Contributions Act, a 1935 law passed alongside the Social Security program to fund retirement and disability benefits. Medicare funding was added in 1965. The taxes collected under FICA go directly into the Social Security and Medicare trust funds.
Social Security, formally Old-Age, Survivors, and Disability Insurance (OASDI), provides monthly cash benefits to retirees, disabled workers, and eligible family members. Medicare, or Hospital Insurance (HI), helps cover hospital and certain medical costs, mainly for people 65 and older and some younger people with disabilities.
Here is a quick snapshot of the 2026 rates, the $184,500 Social Security wage base (up from $176,100 in 2025), the maximum employee Social Security withholding, and when the additional 0.9% Medicare tax kicks in. Use it to check your paycheck or your payroll setup.
Notes: The Social Security rate holds steady from 2025, but the wage base rose from $176,100 to $184,500. Medicare has no wage cap. The Additional Medicare Tax threshold is $250,000 for married filing jointly, $125,000 for married filing separately, and $200,000 for single, head of household, or qualifying surviving spouse.
The 2026 FICA Rate Breakdown, at a Glance
For 2026, the FICA rate components are unchanged from 2025: 6.2% for Social Security and 1.45% for Medicare for employees, matched equally by employers. Self-employed people pay both sides under SECA for a combined 15.3% on applicable earnings.
The Social Security portion applies only up to the annual wage base of $184,500. The Medicare portion has no wage cap, and a 0.9% additional Medicare tax may apply to high earners based on filing status.
Employee FICA in 2026: 6.2% OASDI + 1.45% Medicare = 7.65%
Employer FICA in 2026: 6.2% OASDI + 1.45% Medicare = 7.65%
Self-employed (SECA) in 2026: 12.4% OASDI + 2.9% Medicare = 15.3%, plus any 0.9% additional Medicare tax above thresholds
Social Security (OASDI) Tax Uses a $184,500 Wage Cap in 2026
Employees pay 6.2% of covered wages up to the $184,500 wage base, and employers match that 6.2%. Once your year-to-date wages pass $184,500, no more Social Security tax is withheld for the rest of the year.
The maximum employee Social Security withholding for 2026 is $11,439, which is 6.2% of $184,500. Employers contribute the same amount for every employee who reaches the cap. The wage base rose from $176,100 in 2025 to $184,500 in 2026, so higher earners will see Social Security withholding continue a bit further into the year than they did last year.
Medicare (HI) Tax Has No Wage Cap, But a 0.9% Surtax Can Apply
Medicare tax is 1.45% for employees and 1.45% for employers on all covered wages, with no wage cap. High-income employees may also owe an additional 0.9% Medicare tax on earnings over certain thresholds.
Unlike Social Security, Medicare tax applies no matter how high wages go. Employers must withhold the base 1.45% on all covered pay and begin withholding the 0.9% Additional Medicare Tax once an employee’s wages from that employer exceed $200,000 in the calendar year.
Who Pays the Additional 0.9% Medicare Tax in 2026?
The additional 0.9% Medicare tax applies to wages, compensation, and self-employment income above these filing-status thresholds: $250,000 married filing jointly, $125,000 married filing separately, and $200,000 single, head of household, or qualifying surviving spouse. There’s no employer match for this surtax.
Employer withholding starts once an employee’s wages from that employer exceed $200,000 for the year, regardless of filing status or other income. Any over- or under-withholding gets reconciled on your individual tax return.
Employees and Employers Each Pay 7.65%, With No Match on the 0.9% Surtax
The FICA split in 2026 is straightforward. Employees pay 6.2% to Social Security and 1.45% to Medicare, 7.65% combined, and employers match those exact amounts. Employers don’t match the 0.9% additional Medicare tax; only the employee owes that surtax once their income crosses their filing-status threshold.
Self-Employed Workers Pay 15.3% Under SECA
If you’re self-employed, you pay Self-Employment Contributions Act (SECA) taxes, which mirror both the employee and employer shares: 12.4% for Social Security up to the $184,500 wage base and 2.9% for Medicare on all net earnings. That’s 15.3% combined, before any 0.9% additional Medicare tax on high income.
Self-employment tax is calculated on 92.35% of your net earnings. Half of it is deductible for income-tax purposes, which lowers your adjusted gross income but doesn’t change the SECA rate itself.
If your combined wages and self-employment earnings push you over the additional Medicare threshold for your filing status, you owe the 0.9% surtax on the excess, calculated and paid with your individual tax return.
How to Calculate FICA in 2026: Three Worked Examples
Example 1: Standard W-2 earner below all thresholds
Annual salary of $60,000, filing single. Social Security: 6.2% of $60,000 is $3,720, matched by the employer. Medicare: 1.45% of $60,000 is $870, also matched. No additional Medicare tax applies. Total employee FICA: $4,590.
Example 2: High earner who hits the wage cap and owes the surtax
Annual W-2 wages of $300,000, filing single. Social Security tops out at the employee maximum of $11,439, matched by the employer. Medicare base: 1.45% of $300,000 is $4,350, matched by the employer. Additional Medicare tax: 0.9% of the $100,000 over the $200,000 threshold is $900, with no employer match. Total employee FICA: $16,689.
Example 3: Self-employed professional
Net self-employment income of $120,000, filing jointly. The SE tax base is 92.35% of $120,000, or $110,820. Social Security at 12.4% comes to $13,741.68. Medicare at 2.9% comes to $3,213.78. No additional Medicare tax applies since income is below the joint filing threshold. Total SE tax is $16,955.46, and half of that, $8,477.73, is deductible for income-tax purposes.
Common FICA Exemptions
FICA is mandatory for most wage earners, but a handful of limited exemptions exist. Always confirm the specific facts of your situation before changing withholding or deposit schedules.
Family employment: Some payments to children employed by their parents can be exempt from FICA depending on the relationship and the type of business, under IRC 3121.
Student exception: Services performed for a school, college, or university by a student who is enrolled and regularly attending classes may be exempt from FICA for that employer, under the IRS’s student-FICA rules.
Certain nonresident aliens: Some nonresident students, scholars, teachers, researchers, and trainees in F-1, J-1, M-1, or Q-1/Q-2 status may be exempt from FICA on wages for services performed as nonresidents.
Specific religious groups: Members of a recognized religious sect conscientiously opposed to insurance may qualify for an exemption if they meet IRS criteria and obtain approval through Form 4029.
Government and public sector exceptions: Certain state and local government employees covered by a qualifying public retirement system may fall outside Social Security coverage. Rules vary by employer and hire date
Federal Income Tax vs. FICA: What’s Different in 2026
FICA and federal income tax are separate systems. FICA funds Social Security and Medicare and uses fixed rates and program-specific rules, like the Social Security wage base and the additional Medicare surtax. Federal income tax is pay-as-you-go and depends on your filing status, tax brackets, credits, and deductions.
FICA applies to earned wages and self-employment income, while income tax applies to a broader set of income, like wages, interest, dividends, and capital gains, and gets reconciled annually on your Form 1040. You can adjust income-tax withholding through Form W-4, but FICA withholding isn’t adjustable except where an exemption legally applies.
Overpaid Social Security From Multiple Jobs? Here’s How to Fix It
If you have more than one employer in the same year, each one must withhold Social Security up to the 2026 wage base of $184,500. That can push your combined withholding above the 2026 maximum of $11,439.
If that happens, claim the excess as a credit on your individual tax return. Compare your total Social Security tax withheld, shown in box 4 of your W-2, to the maximum allowed. The difference is refundable on your Form 1040. If a single employer over-withheld by mistake, ask that employer for a payroll correction or refund.
For the additional Medicare tax, your employer starts withholding once your wages from that employer exceed $200,000. Any over- or under-withholding gets trued up on your Form 1040 based on your filing-status threshold. Consider making estimated tax payments or adjusting your Form W-4 withholding if you expect to owe the surtax at year-end.
Tips and Overtime Are Still Subject to FICA
Employees must report tips to their employer so FICA can be properly withheld, and overtime pay is treated as regular wages for FICA purposes. The One Big Beautiful Bill Act created new federal income-tax deductions for qualified tips and overtime, but those are income-tax provisions, not FICA exemptions. Social Security and Medicare tax still applies to every dollar of tips and overtime pay.
Employers in certain industries may be eligible for an income-tax credit related to the employer share of FICA on tipped wages, often called the 45B tip credit. That credit doesn’t reduce the FICA that must be withheld from employees or paid by employers.
