The number on your offer letter is not the number that hits your bank account. Between the two sit three different taxes and a handful of deductions, and most people have only a fuzzy sense of which is which. Once you can name each piece, your pay stub stops being a mystery and becomes something you can actually plan around.
Here is the shape of it for 2026. On an $80,000 salary, a single filer with no special deductions pays about $8,770 in federal income tax and $6,120 in FICA, which is $14,890 in federal taxes before a dollar of state tax. Add state tax, or live somewhere that has none, and the final take-home swings by thousands of dollars.
What gets taken out of a paycheck?
Four things, in a specific order. First come your pre-tax deductions, such as a traditional 401(k) contribution and health insurance premiums. These come out before tax is calculated, which is what makes them pre-tax. Then come the three taxes: federal income tax, FICA, and state income tax. What remains is your take-home pay.
The order matters because pre-tax deductions shrink the income that gets taxed. A dollar you route into a traditional 401(k) is a dollar the income tax never sees, which is the whole appeal.
How is federal income tax calculated on my paycheck?
Federal income tax is charged on your taxable income, not your salary. Taxable income is your pay minus pre-tax deductions minus the standard deduction, which for 2026 is $16,100 for a single filer. That taxable income then runs through the brackets.
The brackets are marginal, which trips people up constantly. A marginal bracket taxes only the slice of income inside its range, so moving into a higher bracket never raises the tax on the income below it. Walk through the $80,000 single example:
- Taxable income: $80,000 minus $16,100 = $63,900.
- 10% on the first $12,400 = $1,240.00
- 12% on the next $38,000 = $4,560.00
- 22% on the remaining $13,500 = $2,970.00
- Total federal income tax: $8,770.00
Your top bracket is 22 percent, but your effective rate, the tax divided by your full salary, is only about 11 percent on income tax alone. That gap between marginal and effective is why “I’m in the 22 percent bracket” never means you pay 22 percent of everything.
What is FICA, and why is it separate?
FICA is the Social Security and Medicare tax, and it plays by completely different rules than income tax. There is no standard deduction and no brackets, just flat percentages on your wages:
- Social Security: 6.2 percent on wages up to the 2026 wage base of $184,500. Above that, no more Social Security tax.
- Medicare: 1.45 percent on all wages, with an extra 0.9 percent on wages above $200,000 ($250,000 married filing jointly).
On the $80,000 salary that is $4,960 plus $1,160, or $6,120. The IRS lays out these rates plainly, and the Social Security Administration publishes the wage base each year. Because FICA ignores the standard deduction, it often takes a bigger bite from a modest paycheck than income tax does.
Why a 401(k) does not cut your FICA
A traditional 401(k) lowers your income tax but not your Social Security or Medicare, because FICA is charged on your gross wages before that deduction. This is also why your future Social Security benefit is based on your full salary, not your salary after 401(k) contributions.
How much does my state take?
This is where two people with identical salaries end up with very different paychecks. State income tax ranges from nothing to over 13 percent at the top.
| State | State income tax | Annual take-home |
|---|---|---|
| Texas / Florida / Washington | $0 | $65,110 |
| Pennsylvania (flat 3.07%) | $2,456 | $62,654 |
| California (progressive) | $3,347.98 | $61,762 |
| New York (progressive) | $3,723 | $61,387 |
Nine states tax no wage income at all, so in Texas, Florida, or Washington the $80,000 nets about $65,110 a year. A flat-tax state like Pennsylvania takes a single percentage off the top. A progressive state like California or New York uses its own brackets and standard deduction. You can run your own salary in any of the state paycheck calculators to see the split.
How do I raise my take-home pay?
Mostly by lowering taxable income, not by chasing the brackets. The honest levers:
- Contribute to a traditional 401(k) or HSA. Each pre-tax dollar cuts your income tax at your marginal rate, though it also leaves your paycheck.
- Check your W-4. If you got a large refund last year, you over-withheld and gave the government an interest-free loan; adjusting your W-4 puts that money in each paycheck instead.
- Consider where you live and work. State tax is a real cost, and for remote workers it can be a genuine variable.
What does not work is fearing a raise because it might “push you into a higher bracket.” Because brackets are marginal, only the dollars above the threshold are taxed at the higher rate. A raise always leaves you with more take-home, never less.
The bottom line
Your paycheck is your salary minus pre-tax deductions, federal income tax, FICA, and state tax, in that order. Federal income tax uses marginal brackets after the standard deduction, FICA is a flat tax on wages with no deduction, and state tax depends entirely on where you are. Once you see the four pieces, you can use a federal tax estimate and a state paycheck calculator to predict your take-home before you ever sign the offer.
