You open your pay stub, scan down the deductions, and there it is. A line that says FICA, sometimes two or three of them. It’s one of the most common questions we hear from new employees and first-time employers alike. So what is FICA tax, exactly, and why does it keep showing up every payday?
Here’s the quick version. Every cent of it is earmarked for Social Security and Medicare. Your employer takes your share out before you’re paid, matches it dollar for dollar, and forwards both amounts to the IRS. Employees never file anything for it, so most people don’t think about it until their take-home pay looks lower than they’d hoped.
Below, we’ll walk through what FICA tax is, what it costs in 2026, how to read those codes on your stub, and a couple of real paycheck examples so you can check your own numbers.
What Is FICA Tax?
Spelled out, FICA means Federal Insurance Contributions Act, a law with roots in the 1930s that still shapes every paycheck today. The idea behind it is pretty old-fashioned. Workers chip in, their bosses chip in, and the pot pays for Social Security and Medicare.
If you’re after a plain FICA taxes definition, try this one. It’s a flat-rate payroll tax on earned income, and the money goes to retirement, disability, survivor and hospital benefits.
What makes it different from the income tax you file each April?
- Everyone pays the same rate, no matter their bracket.
- Your employer pays a share equal to yours.
- There’s no standard deduction, so it starts with your first dollar.
- You almost never see it come back in a refund.
So, put plainly, what is FICA tax? It’s your regular payday contribution to the two biggest safety-net programs in the US.
What Are FICA Taxes Made Of?
You’ll often see the question phrased as what are FICA taxes, plural. That’s because FICA is really two separate taxes rolled into one deduction, plus a small extra charge for higher earners.
Social Security Tax
This is the big one. Your share is 6.2% of wages, and your employer kicks in a matching 6.2%. Once you earn past the yearly wage cap, it stops until January.
Medicare Tax
Medicare takes 1.45% from you and 1.45% from your employer. There’s no cap here. Earn $50,000 or $5 million, and every dollar gets taxed.
Additional Medicare Tax
High earners pay a bit more. Once your pay crosses $200,000 in a calendar year, your employer has to start holding back another 0.9% on the excess, and it doesn’t match this one. When you file your return, the true threshold depends on filing status. It’s $250,000 for joint filers and $125,000 if you’re married and filing separately.
FICA Tax Rates and Limits for 2026
Knowing what is FICA tax only helps if you also know this year’s numbers. The percentages haven’t moved in decades. What does shift is the wage cap, which usually climbs a little each year.
| Item | Employee | Employer | Total |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% |
| Medicare | 1.45% | 1.45% | 2.9% |
| Total FICA | 7.65% | 7.65% | 15.3% |
| Additional Medicare (wages over $200,000) | 0.9% | None | 0.9% |
The 2026 cap sits at $184,500. That’s up from $176,100 last year, per the Social Security Administration’s 2026 fact sheet. That means the largest Social Security deduction any one employee can see this year is $11,439. Medicare, on the other hand, is charged on every dollar with no ceiling.
Planning ahead? The SSA has already announced a $192,300 cap for 2027, with the same rates. The IRS page on withholding rates is a good place to double-check before you run payroll.

What’s FICA on My Paycheck?
If you’ve ever typed “what’s FICA on my paycheck” into Google, you’re not alone. The line you’re seeing is your portion of Social Security and Medicare, calculated on what you earned before deductions in that pay period.
The confusing part is the labels. Every payroll provider seems to use its own shorthand, so the same deduction can look completely different from one employer to the next.
FICA EE Meaning and Other Pay Stub Codes
Let’s clear up the FICA EE meaning first. EE means employee. It’s the slice that actually comes out of your check. ER means employer, and when a stub shows it, it’s just telling you what your company paid on your behalf. Your take-home pay isn’t touched by that number.
Here’s a cheat sheet for the codes you’re likely to run into:
| Pay stub code | What it means |
|---|---|
| FICA-SS, SS, OASDI, SOC SEC | Social Security tax (6.2%) |
| FICA-MED, MED, MEDI, HI | Medicare tax (1.45%) |
| FICA EE | Your share of FICA |
| FICA ER | Your employer’s share (not deducted from you) |
| ADDL MED | Additional Medicare tax (0.9%) |
A small detail that trips people up. Health premiums you pay through a cafeteria plan usually reduce the wages FICA is figured on. Your 401(k) contributions don’t, even though they cut your income tax.
FICA Tax Calculation: Two Real Paycheck Examples
Good news, the math isn’t hard. Grab your gross pay for the pay period and multiply it by 7.65%. Unless you’ve already earned past the Social Security cap, that number is your FICA.
Example 1: Salary of $60,000
Say Maria makes $60,000 and gets paid every other week. Her gross check comes to about $2,307.69.
- Social Security at 6.2% comes to $143.08
- Medicare at 1.45% comes to $33.46
- So $176.54 leaves each check for FICA
By December, she’s paid $4,590. Her employer has quietly paid the same $4,590 on top of her salary.
Example 2: Salary of $250,000
Now take James, who’s single and earns $250,000. Two extra rules kick in for him.
- Social Security only touches his first $184,500, so he pays $11,439
- Medicare hits the whole $250,000, which is $3,625
- The extra 0.9% on his last $50,000 adds $450
- All in, he pays $15,514 for the year
Something nice happens for James in the fall. Once he passes $184,500, the Social Security line disappears and his paychecks get bigger for the rest of the year.
Who Pays the FICA Tax?
Pretty much anyone who earns a paycheck or runs a business in the US. The only real difference is who handles the paperwork.
Employees
There’s nothing on your to-do list here. Your employer takes care of withholding, and when your W-2 shows up in January, Box 4 has your Social Security total and Box 6 has Medicare.
Employers
On the business side, the job is bigger. You hold back each worker’s 7.65%, put in your own 7.65%, and send it all to the IRS, either monthly or semiweekly depending on your deposit schedule. Then once a quarter, you report it on Form 941. Sloppy payroll records make all of this harder, so good accounting and bookkeeping really pays off here.
Self-Employed Workers
Work for yourself? Then you’re the boss and the worker at once, so both halves land on you. The IRS has its own name for this, self-employment tax. The rate is 15.3%, but it’s charged on 92.35% of net earnings rather than the full amount.
Let’s say you freelance and clear $80,000 in profit. You’d owe roughly $11,304, though you get to deduct about $5,652 of it on your income tax. No one is withholding this from client payments, so you’ll want to send quarterly estimated payments. Doing a bit of strategic tax planning early in the year beats scrambling in April.
What Does FICA Tax Pay For?
It’s a fair question. If money comes out of every check, what does FICA tax pay for? It doesn’t go into a personal savings account. It goes into federal trust funds that pay current beneficiaries.
- Retirement checks, once you’ve built up enough work credits. For most people that’s about 10 years on the job.
- Disability pay if a serious condition stops you from working.
- Survivor benefits that help a spouse or kids after a worker dies.
- Medicare Part A, which pays hospital bills. That includes inpatient stays, skilled nursing and hospice, mostly for people 65 and older.
In other words, today’s paychecks support today’s retirees. When your turn comes, the workers behind you will be doing the same.
FICA Tax vs Federal Income Tax
Since they’re both pulled from the same check, people lump them together all the time. Look closer, though, and the two run on completely separate rules.
| Feature | FICA Tax | Federal Income Tax |
|---|---|---|
| Rate | Flat 7.65% for employees | Progressive brackets |
| Changes with your W-4 | No | Yes |
| Income cap | Yes, for Social Security | No |
| Refund possible | Rarely | Yes, if overwithheld |
| What it funds | Social Security and Medicare | General federal budget |
That table explains a common surprise. Your refund never includes FICA because only income tax withholding gets trued up on your return.
For business owners, the employer share matters most. Every hire really costs about 7.65% more than the salary you agree on. Our CFO services team builds that into your budget and cash flow forecast, so payroll taxes never catch you off guard.
Can You Get FICA Tax Back?
Usually not. There are two situations where you can, though.
The first one catches people who change jobs mid-year or hold two jobs. Your two employers don’t talk to each other, so each one keeps withholding Social Security as if it’s your only job. Once your combined pay tops $184,500, you’ve likely paid too much. You can get that back as a credit on your Form 1040.
The second is a plain payroll error at one company. If a single employer takes more than the annual max, you’ll need to ask them to fix it and pay you back directly.
A few groups don’t pay FICA at all. Some students who work for their own college are exempt, as are certain nonresident aliens on specific visas and members of religious groups with an approved exemption.

Tips for Employers to Stay FICA Compliant
From what we see working with small businesses, payroll tax slip-ups are some of the most expensive mistakes to fix. The money you withhold from employees was never really yours. It belongs to the IRS, and if it doesn’t get deposited, the people responsible for payroll can end up personally on the hook.
Here’s what we’d tell any owner running payroll:
- Let payroll software handle rate and wage cap updates each January, so nobody is typing them in by hand.
- Keep an eye on year-to-date pay for your higher earners. Social Security should stop right at the cap.
- Kick off the 0.9% Additional Medicare withholding the same pay period someone crosses $200,000.
- Deposit on time, every time, and make sure your deposits line up with Form 941.
- Reconcile payroll accounts once a month. A $20 mistake is easy to fix in March and painful in December.
Payroll problems rarely start big. Our article on common bookkeeping mistakes shows how small slips turn into cash flow headaches. And if your books have fallen behind, catch-up accounting can bring them current before your next quarterly filing.
Final Thoughts
That covers what is FICA tax, how it’s calculated, and why you see it on every check. For employees, it mostly comes down to knowing how to read a pay stub. For business owners and the self-employed, it’s an ongoing job that depends on accurate records all year.

FAQs
What is FICA tax in simple words?
It’s a 7.65% federal payroll tax on your wages that funds Social Security and Medicare. Your employer pays a matching 7.65%.
Is FICA the same as Social Security tax?
Not quite. Social Security is one piece of FICA. Medicare is the other, and the two together add up to the 7.65% you see withheld.
Why is FICA taken out of my paycheck?
Federal law requires employers to withhold it. The money funds Social Security and Medicare, which you may rely on later.
Do I get FICA back in my tax refund?
Generally no. Refunds only return extra income tax. The exception is excess Social Security tax from working for more than one employer in a year.
What happens if I earn more than the Social Security limit?
Social Security tax stops once your 2026 wages pass $184,500. Medicare keeps applying to every dollar.
Do self-employed people pay FICA?
Yes. They pay both halves as self-employment tax, which works out to 15.3% on most of their net earnings.
