FICA is the 7.65% payroll tax that funds Social Security (6.2%) and Medicare (1.45%). Here’s how it shows up on your pay stub, when Social Security stops at $176,100, and what you’ll pay at common salary levels.

Quick Summary
- FICA is the payroll tax that funds Social Security + Medicare
- Most employees pay 7.65% of wages (6.2% Social Security + 1.45% Medicare)
- Social Security stops after $176,100 of wages in a year (2025 wage base); Medicare has no cap
- On $60,000/year, estimated employee FICA is $4,590/year (~$176 per biweekly paycheck)
If you’ve ever looked at your pay stub and thought “What is FICA and why is it taking money out of every paycheck?” — you’re not alone. The short version: FICA is the part of your paycheck that funds Social Security and Medicare, and it’s separate from federal income tax.
Let’s break it down with real numbers so you can sanity-check your pay stub in 60 seconds.
FICA in plain English (what it is and where you see it)
FICA stands for the Federal Insurance Contributions Act. In normal human terms, it’s a payroll tax split into two line items:
- Social Security tax
- Medicare tax
On most pay stubs, you’ll see them labeled something like “Social Security” and “Medicare” (or “OASDI” for Social Security). These are withheld from each paycheck automatically.
📊 Key Number
For most W-2 employees, the FICA you personally pay is 7.65% of wages. That’s on top of any federal and state income tax withholding.
Your employer also pays a matching amount (their half doesn’t show on your paycheck). We’ll cover that below.
FICA rates and caps (the numbers that matter)
FICA has two parts with very different rules:
- Social Security: 6.2% on wages up to $176,100 (2025 wage base). After you earn $176,100 with a single employer in a calendar year, Social Security withholding stops for the rest of that year.
- Medicare: 1.45% on all wages (no cap). If your wages exceed $200,000 from a single employer, you may also see an extra 0.9% Medicare surtax on the amount above $200,000.
⚠️ Heads Up
FICA is a payroll tax. It is not based on your W-4 allowances the way federal income tax withholding is. Even if your federal withholding is $0, you can still owe full Social Security and Medicare on every paycheck.
What FICA costs at common salary levels
Here’s what the employee side of FICA looks like at common salaries (rounded). Biweekly assumes 26 paychecks/year.
| Annual salary | Social Security (6.2%) | Medicare (1.45%) | Total employee FICA/year | Per biweekly paycheck |
|---|---|---|---|---|
| $40,000 | $2,480 | $580 | $3,060 | $118 |
| $60,000 | $3,720 | $870 | $4,590 | $176 |
| $90,000 | $5,580 | $1,305 | $6,885 | $265 |
| $140,000 | $8,680 | $2,030 | $10,710 | $412 |
| $200,000 | $10,918 (capped) | $2,900 | $13,818 | $531 |
Note: Social Security is capped at the wage base ($176,100). Medicare has no cap. The 0.9% Additional Medicare Tax may apply above $200,000.
If you want your full take-home number (including state income tax, local taxes, and benefits), run your exact situation in a state calculator like California and Texas — the difference between states shows up in income tax, not in FICA.
What counts as “wages” for FICA (and what doesn’t)
For most employees, FICA is calculated on your gross wages before many (but not always all) benefits deductions. Here are the two rules that trip people up:
- 401(k) contributions: usually reduce federal income tax, but do not reduce FICA.
- Some pre-tax benefits: like certain health insurance premiums may reduce taxable income for income tax purposes, but they often still don’t change FICA the way people expect.
The fastest way to verify is simple: take your gross pay for the period and multiply by 6.2% and 1.45%. Your pay stub should be very close (minor rounding differences are normal).
💡 Action Tip
If your goal is to boost take-home pay, treat FICA as a fixed “baseline” and focus on the things you can control: W-4 settings, state withholding, and benefits choices.

Common paycheck surprises (and how to fix them)
1) “I worked two jobs and Social Security got withheld twice.”
This is normal. Each employer withholds Social Security as if you only work for them. If your total wages across all jobs exceed the wage base, you can claim the excess back when you file your Form 1040.
2) “My paycheck got bigger near the end of the year.”
If your salary is high enough, you may hit the Social Security cap. Once you’ve earned $176,100 from a single employer, Social Security withholding stops — but Medicare continues. That’s why the jump isn’t huge; it’s “just” 6.2% of wages.
3) “My federal withholding is $0 — why is FICA still coming out?”
Because they’re different taxes. Federal income tax depends on your W-4 and deductions. FICA is a payroll tax that applies regardless of your W-4, as long as your wages are subject to Social Security and Medicare.
⚠️ Heads Up
If Social Security or Medicare withholding is missing on a W-2 paycheck when you expect it, don’t ignore it. Payroll errors happen, and they create an ugly surprise later. Ask payroll to confirm your classification and fix it quickly.
How to put this to work (3 quick steps)
1) Check your pay stub line items. You should usually see separate lines for Social Security and Medicare. If you don’t, that’s your cue to ask payroll what label they use (some stubs use “OASDI” for Social Security).
2) Do a 30-second math check. Multiply your gross pay for the period by 0.062 and 0.0145. Your withholdings should be very close.
3) Run your full take-home in your state. FICA is the same nationwide, but state income tax isn’t. Use a state calculator like California or Texas to see the complete picture (and to compare a move).
