Federal income tax is charged in bands: the first slice of taxable income is taxed at 10%, the next at 12%, and so on up to 37%. Your bracket is the rate on the last dollar, not the rate on everything, which is the most common misunderstanding about tax.
Federal income tax on $85,000
$8,550.00
Taxable income of $62,900.00 after a $16,100.00 standard deduction
| Rate | Income taxed at this rate | Tax |
|---|---|---|
| 10% | $12,400.00 | $1,240.00 |
| 12% | $38,000.00 | $4,560.00 |
| 22% | $12,500.00 | $2,750.00 |
| Total federal income tax | $8,550.00 |
Only the income inside each band is taxed at that band rate, so crossing into the 24% bracket is never 24% of the whole income.
| Line | Amount |

| Less standard deduction | -$16,100.00 |

| Take-home pay per month | $5,328.96 |
Payroll tax is charged on gross wages before almost every deduction, which is why it does not shrink when your taxable income does.
Enter your gross income and this calculator walks the 2026 brackets, adds Social Security, Medicare and an optional flat state rate, then shows the monthly take-home pay that is left.
Pre-tax deductions come off the top: 401(k) or 403(b) contributions, HSA and FSA contributions and the share of health premiums payroll takes before tax. What remains is adjusted gross income.
Next comes the standard deduction, or your itemised deductions if they are larger. Only what survives both steps is taxable income, and only taxable income is fed through the brackets.
Each band is charged at its own rate. A single filer with $85,000 of income pays 10% on the first $12,400 of taxable income, 12% on the next $38,000, 22% on the rest, and the top dollar sits in the 22% band.
That is why a raise can never reduce take-home pay: extra income is taxed at the margin, and the income below it keeps its old rate. Credits are different - they come straight off the tax itself, so a $2,000 credit is worth exactly $2,000.
Social Security takes 6.2% of wages up to the annual wage base, which is $184,500 for 2026, and Medicare takes 1.45% with no cap. These are charged on gross wages, before the standard deduction, which is why they barely move when taxable income falls.
Additional Medicare tax of 0.9% starts above $200,000 for single and head of household filers and $250,000 for joint filers. Employers withhold it once wages pass $200,000 regardless of filing status, and the return settles any difference.
A flat rate is enough for an estimate, because most states that charge income tax have a graduated scale and deductions of their own. A handful charge no tax on wage income at all.
Local income tax, city wage tax and school district tax come on top in some places. When you compare two job offers in different states, that is where the numbers diverge most.

Federal income tax on $85,000
$8,550.00
Taxable income of $62,900.00 after a $16,100.00 standard deduction
The 401(k) contribution leaves the tax base entirely, so it cuts income tax without touching Social Security or Medicare.
Federal income tax on $85,000
$5,120.00
Taxable income of $46,800.00 after a $32,200.00 standard deduction
Brackets are twice as wide and the standard deduction is doubled, so the same salary carries a lower effective rate.
Federal income tax on $150,000
$21,854.00
Taxable income of $121,900.00 after a $16,100.00 standard deduction
State tax is charged on adjusted gross income, so it starts from more than the federal tax base does.
The bracket is the rate on your last dollar of income. The effective rate is total tax divided by gross income. A single filer on $85,000 has a 22% bracket but an effective federal rate closer to 11%.
No. Only income above each threshold is taxed at the higher rate, so every extra dollar adds take-home pay even at the top bracket. A raise can reduce the value of credits or deductions that phase out with income, which is a different effect.
Whichever is larger. For 2026 the standard deduction is $16,100 single, $32,200 married filing jointly and $24,150 for head of household. You need mortgage interest, state and local tax, charity and medical costs above that before itemising pays.
Payroll tax is charged on gross wages. Retirement contributions and the standard deduction reduce income tax only, so a filer with a small taxable income can still carry a large payroll tax bill.
Yes. The brackets and standard deduction are the inflation-adjusted figures from IRS Revenue Procedure 2025-32, and the payroll rates and wage base come from IRS Publication 15 for 2026.
Not in these brackets: long-term gains have their own 0%, 15% and 20% ladder. The capital gains calculator on this site covers that case, including the 3.8% net investment income tax.
