FICA Tax Explained: Social Security & Medicare Breakdown (2026)

FICA is the largest payroll tax most Americans pay, yet many don't understand what it is, how it's calculated, or where the money goes. This guide breaks down everything about the Federal Insurance Contributions Act tax.

What Is FICA?

FICA stands for Federal Insurance Contributions Act. It's a payroll tax that funds two critical social programs:

1. Social Security (OASDI) — retirement, disability, and survivor benefits
2. Medicare (HI) — healthcare for people aged 65+

FICA isn't optional — it's withheld from every paycheck automatically, and your employer matches your contribution dollar for dollar.

2026 FICA Tax Rates

Key Numbers for 2026

• Social Security wage base: $184,500 — you stop paying SS tax after earning this amount
• Medicare: No wage cap — you pay on ALL earnings
• Additional Medicare threshold: $200,000 (single) / $250,000 (married filing jointly)

How FICA Is Calculated on Your Pay Stub

Let's walk through a real example:

Employee: $75,000 annual salary, paid bi-weekly (26 pay periods) Gross pay per period: $2,884.62

Your employer pays the same $5,737.50, meaning the total FICA contribution for your employment is $11,475.

Social Security Deep Dive

The $184,500 Wage Cap

In 2026, Social Security tax only applies to the first $184,500 of earnings. After that, no more SS is withheld.

What this means for high earners:

• Maximum SS contribution: $184,500 × 6.2% = $11,439.00
• If you earn $250,000: You stop paying SS tax in October
• Your paycheck gets noticeably larger in Q4

What Does Social Security Fund?

• Retirement benefits — monthly payments starting at age 62-70
• Disability benefits (SSDI) — income for disabled workers
• Survivor benefits — payments to spouses and children of deceased workers
• Supplemental Security Income (SSI) — need-based assistance

Medicare Deep Dive

No Wage Cap

Unlike Social Security, Medicare tax applies to ALL earnings with no cap. Whether you earn $30,000 or $3 million, you pay 1.45% on every dollar.

Additional Medicare Tax (0.9%)

High earners pay an extra 0.9% Medicare tax on wages above:

• $200,000 — single filers
• $250,000 — married filing jointly
• $125,000 — married filing separately

Example: If you earn $250,000 as a single filer:

• First $200,000: $200,000 × 1.45% = $2,900
• Next $50,000: $50,000 × 2.35% (1.45% + 0.9%) = $1,175
• Total Medicare: $4,075

Note: Your employer does not match the additional 0.9%.

FICA for Self-Employed Workers

Self-employed individuals pay both the employee and employer portions, called self-employment tax (SE tax):

However, you can deduct the employer-equivalent portion (7.65%) as an adjustment to income on your tax return.

Use current IRS Schedule SE instructions and a qualified tax professional for a situation-specific self-employment tax result. A paycheck estimate or paystub draft does not calculate a complete tax return.

FICA vs. Income Tax

People often confuse FICA with income tax. Here's the key difference:

Common FICA Questions

Can FICA be reduced or avoided?

For most workers, no. FICA is mandatory. However:

• Religious exemptions: Members of certain religious groups (like the Amish) may be exempt
• Student FICA exemption: Students working at the school they attend may be exempt
• Certain visa holders: Some nonresident aliens on specific visas

What if my employer withheld too much FICA?

If you change jobs mid-year and your combined earnings exceed the SS wage base, each employer withholds SS independently. You'll recover the excess when you file your tax return.

Do I pay FICA on bonuses?

Yes. Bonuses, commissions, and all forms of compensation are subject to FICA. Bonuses are often withheld at a flat 22% for income tax, but FICA is always 7.65%.

Frequently Asked Questions

What does FICA stand for on my pay stub?

FICA stands for Federal Insurance Contributions Act. It's the combined Social Security and Medicare tax totaling 7.65% of your gross pay. You may see it listed as one line (FICA) or split into SS/OASDI and MED/Medicare.

Why is FICA so high?

At 7.65%, FICA is actually one of the more moderate payroll taxes globally. It feels high because it's a flat tax with no standard deduction — every dollar you earn (up to the SS cap) is taxed at the full rate, unlike income tax which has brackets.

Do employers pay FICA too?

Yes. Your employer matches your FICA contribution exactly — 6.2% for Social Security and 1.45% for Medicare. This is why the "total" FICA rate is 15.3%, even though only 7.65% appears on your pay stub.

Is FICA the same as payroll tax?

FICA is one component of payroll taxes. "Payroll tax" is a broader term that also includes federal and state unemployment taxes (FUTA/SUTA), which employers pay but employees generally don't.

When will I benefit from FICA?

You become eligible for Social Security retirement benefits at age 62 (reduced) or your full retirement age (66-67 depending on birth year). Medicare coverage begins at age 65. The more you pay in, the higher your future benefits.
