How US federal income tax works
A $75,000 salary puts you in the 22% federal bracket, yet federal income tax takes only 10.23% of your pay.
That gap trips up a lot of people, and it comes down to two things. The standard deduction comes off first. Then the rates apply in slices.
The $16,100 comes off first
A single filer who takes the standard deduction in 2026 subtracts $16,100 from pay. What is left is taxable income. On $75,000 that is $58,900. Our calculators assume this deduction and nothing else.
Brackets are slices of taxable income
| Taxable income | Rate |
|---|---|
| $0 to $12,400 | 10% |
| $12,401 to $50,400 | 12% |
| $50,401 to $105,700 | 22% |
| $105,701 to $201,775 | 24% |
| $201,776 to $256,225 | 32% |
| $256,226 to $640,600 | 35% |
| $640,601 and above | 37% |
Each rate applies only to the part of your income inside its range. Here is $58,900 cut up:
| Slice | Taxable income in it | Tax |
|---|---|---|
| 10% slice | $12,400 | $1,240 |
| 12% slice | $38,000 | $4,560 |
| 22% slice | $8,500 | $1,870 |
| Federal income tax | $7,670 |
$7,670 on $75,000 is 10.23%. That is your average rate. The 22% is your marginal rate, the rate on your next dollar.
Why a raise never shrinks your paycheck
People turn down overtime because it will "put them in a higher bracket". It does not work that way. Say you earn $66,400, so $100 of your taxable income still sits below the top of the 12% bracket, and you get a $1,000 raise. $100 of it is taxed at 12%. The other $900 is taxed at 22%. Extra federal tax: $210. You keep the rest, before FICA and state tax.
Marginal and average rate at other salaries
| Salary | Federal tax | Average rate | Marginal rate |
|---|---|---|---|
| $40,000 | $2,620 | 6.55% | 12% |
| $60,000 | $5,020 | 8.37% | 12% |
| $100,000 | $13,170 | 13.17% | 22% |
| $150,000 | $24,734 | 16.49% | 24% |
| $250,000 | $51,304 | 20.52% | 32% |
At $250,000 the marginal rate is 32% while the average is 20.52%. The average trails the marginal rate at every salary, because the lower slices never go away.
Brackets are set on taxable income, so each one starts $16,100 higher in salary terms. The 12% rate begins at a salary of about $28,500.
The "Fed Withholding" line on your paystub is your employer's running estimate of this bill. It is not the final number. Your W-4 steers the estimate, and any gap is settled when you file your return. A big refund only means too much was held back along the way. Social Security and Medicare are separate, and FICA explained covers them. Most states add their own income tax on top. You can see every deduction together on the $75,000 salary page, or try your own salary.
Figures on this page assume a single filer who is a W-2 employee and takes the standard deduction.
