FICA Tax Explained: Social Security & Medicare in 2026
FICA tax explained for workers: what the 7.65% deduction on your paycheck is, the 2026 wage base, the Additional Medicare Tax, and why overtime still pays FICA.

Look at your pay stub and you will see a line marked FICA, or maybe two lines labeled Social Security and Medicare. That is money leaving your check before it ever reaches your bank account. Most people never learn what it is or how the number gets calculated.
This guide breaks FICA down the way it actually shows up on a paycheck: what the letters mean, the exact rates, the 2026 wage base, and a few edge cases (overtime, bonuses, multiple jobs) that trip people up.
What Is FICA Tax?
FICA stands for the Federal Insurance Contributions Act. It is a mandatory federal payroll tax that funds two programs: Social Security and Medicare.
FICA is not federal income tax. Income tax is progressive, meaning the rate climbs as you earn more, and it depends on your W-4 and filing status. FICA is a flat tax that applies to nearly all wage income from the first dollar. On your pay stub they sit on separate lines because they are separate taxes going to separate places.
The tax dates back to the Social Security Act of 1935, and the Medicare portion was added in 1965. It is split between you and your employer. You pay half out of your wages, and your employer pays a matching half on your behalf.
Because it comes out of gross pay, FICA is one of the reasons your take-home is smaller than your salary suggests. If you have ever wondered why your paycheck is lower than expected, FICA is usually part of the answer.
The Two Parts of FICA: Social Security and Medicare
Your share of FICA is 7.65% of your wages. That single number is actually two taxes stacked together.
| Tax | Employee rate | Employer rate | Combined |
|---|---|---|---|
| Social Security | 6.2% | 6.2% | 12.4% |
| Medicare | 1.45% | 1.45% | 2.9% |
| Total FICA | 7.65% | 7.65% | 15.3% |
You pay 7.65% and your employer matches it, so 15.3% of your covered wages goes into the system in total. Source: IRS Topic No. 751.
Here is a worked example on a simple $1,000 paycheck:
- Social Security: $1,000 × 6.2% = $62.00
- Medicare: $1,000 × 1.45% = $14.50
- Total FICA withheld: $76.50
So on every $1,000 you earn, $76.50 goes to FICA. Your employer quietly pays another $76.50 on top. This is the flat, predictable piece of your withholding, and it lands the same way whether you are salaried or hourly. For the bigger picture of gross pay versus net pay, FICA is one of a handful of deductions that separate the two.
The 2026 Social Security Wage Base ($184,500)
Social Security tax does not apply to unlimited income. It stops once your wages hit an annual cap called the wage base.
For 2026, the Social Security wage base is $184,500, up from $176,100 in 2025 (source: SSA 2026 COLA Fact Sheet). Once your year-to-date wages cross that figure, the 6.2% Social Security tax stops for the rest of the year.
Medicare works differently. It has no wage base, so the 1.45% keeps coming out of every dollar you earn, no matter how high your income goes.
Two details matter here:
- The cap resets every January. The wage base is an annual figure, so on January 1 the 6.2% starts over from zero.
- The cap is applied per employer. Each employer tracks your wages independently against the base.
That second point is a real issue for people with more than one job. If you work two jobs and each pays you a large salary, both employers withhold Social Security up to the cap without knowing about the other. Your combined wages can push you over $184,500, and you end up overpaying Social Security. You get the excess back when you file. If you are juggling more than one W-2, our guide on filing taxes with multiple jobs covers how that credit works.
The Additional Medicare Tax (0.9%)
Higher earners pay an extra layer of Medicare tax. On top of the standard 1.45%, wages above certain thresholds carry an Additional Medicare Tax of 0.9%.
The threshold depends on your filing status:
| Filing status | Additional Medicare Tax threshold |
|---|---|
| Single / Head of Household | $200,000 |
| Married Filing Jointly | $250,000 |
| Married Filing Separately | $125,000 |
Source: IRS Additional Medicare Tax Q&A.
Two things surprise people about this tax. First, there is no employer match on the 0.9%. Unlike the base Medicare tax, your employer does not pay a matching share of the additional amount.
Second, your employer withholds the extra 0.9% once your wages with that employer pass $200,000, regardless of your actual filing status. So a married couple filing jointly might have the tax withheld starting at $200,000 even though their real threshold is $250,000. That difference gets reconciled on your tax return, where you either owe more or get some back based on your true filing status and combined income.
Does FICA Apply to Overtime, Bonuses, and Tips?
Yes to all three. FICA applies to almost all forms of wage compensation, not just your base hourly pay. Overtime, bonuses, commissions, and reported tips are all subject to the full 7.65%.
This is where a lot of confusion crept in for 2026. A new federal “no tax on overtime” deduction lets many workers deduct a portion of their overtime premium, and people assumed that meant overtime pay comes out tax-free. It does not.
The deduction reduces federal income tax only. It is an income-tax deduction you claim, not a payroll-tax exemption. Every overtime dollar still pays the full 6.2% Social Security and 1.45% Medicare, exactly like your regular wages. For the full picture of how that deduction actually works, see our breakdown of the no tax on overtime deduction for 2026.
Say you pick up an overtime shift and earn an extra $300 in time-and-a-half. FICA takes $22.95 of it (6.2% + 1.45%), income-tax deduction or not. If you want to see how overtime stacks up before deductions, the overtime calculator shows the gross side of the math.
Bonuses work the same way. A holiday bonus or a quarterly incentive is wage income, so FICA applies. The only real variable is how income tax is withheld on the bonus, not whether FICA hits it.
Self-Employed? You Pay Both Halves (15.3%)
When you have an employer, the 15.3% is split down the middle: you pay 7.65% and they pay 7.65%. When you work for yourself, there is no employer to cover the other half.
Self-employed workers pay the full 15.3% through self-employment tax, sometimes called SECA. That is the same 12.4% Social Security plus 2.9% Medicare, just paid entirely by you.
There is a partial offset. The IRS lets you deduct the employer-equivalent half of your self-employment tax above the line, which lowers your taxable income. It does not reduce the FICA-equivalent tax itself, but it softens the income-tax side.
The same wage base and Additional Medicare thresholds apply to self-employment income, so the 12.4% Social Security portion stops at $184,500 for 2026 while the Medicare portion keeps going.
How to See Your FICA on Every Paycheck
FICA is one of the most predictable deductions on your pay stub, which makes it easy to check. Find the Social Security and Medicare lines, then run the math: 6.2% and 1.45% of your gross wages for the period.
If the numbers do not line up, that is worth a closer look. Our guide on how to read a pay stub walks through each line so you can spot an error. And if you want to understand what percentage of your paycheck goes to taxes overall, FICA is the flat, reliable piece underneath your variable income tax.
There is one wrinkle worth knowing. Pre-tax deductions like a traditional 401(k) reduce your taxable income for income tax but not always for FICA. A 401(k) contribution still pays Social Security and Medicare, which is why your FICA can look higher than you expect relative to your income tax.
This is exactly the kind of to-the-cent math that gets tedious by hand. ClockWage44 logs your shifts across as many jobs as you want and resolves Social Security, Medicare, the wage base, and the Additional Medicare Tax right inside your take-home figure, all on-device. If you would rather see the whole paycheck estimate at once instead of checking each line, the app does the breakdown for you.

Frequently Asked Questions
What does FICA stand for?
FICA stands for the Federal Insurance Contributions Act. It is the federal payroll tax that funds Social Security and Medicare, split between you and your employer.
How much FICA is taken out of my paycheck?
7.65% of your wages: 6.2% for Social Security and 1.45% for Medicare. Social Security stops at the annual wage base ($184,500 in 2026), but the 1.45% Medicare tax continues on every dollar you earn.
Is FICA the same as federal income tax?
No. FICA is a separate flat payroll tax that funds Social Security and Medicare. Federal income tax is a progressive tax based on your W-4 and total income, and the two are withheld as different lines on your pay stub.
Does FICA apply to overtime pay?
Yes. The 2026 "no tax on overtime" deduction only reduces federal income tax, not FICA. Every overtime dollar still pays the full 7.65% for Social Security and Medicare.
Do I get FICA tax back?
Generally no. The exception is if you overpaid Social Security by working multiple jobs and your combined wages passed the wage base, in which case you reclaim the excess when you file your tax return.
Do self-employed people pay FICA?
Yes, in the form of self-employment tax (SECA). Self-employed workers pay both the employee and employer halves for a combined 15.3%, and half of that amount is deductible above the line on their return.
