The United States uses a progressive income tax: your income is sliced into bands and each slice is taxed at its own rate. There are seven rates for 2026, and the dollar thresholds move with inflation each year.
The 2026 brackets
These apply to taxable income — after your standard or itemised deduction.
| Rate | Single | Married | Separate | Head of household |
|---|---|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 | $0 – $12,400 | $0 – $17,700 |
| 12% | $12,400 – $50,400 | $24,800 – $100,800 | $12,400 – $50,400 | $17,700 – $67,450 |
| 22% | $50,400 – $105,700 | $100,800 – $211,400 | $50,400 – $105,700 | $67,450 – $105,700 |
| 24% | $105,700 – $201,775 | $211,400 – $403,550 | $105,700 – $201,775 | $105,700 – $201,750 |
| 32% | $201,775 – $256,225 | $403,550 – $512,450 | $201,775 – $256,225 | $201,750 – $256,200 |
| 35% | $256,225 – $640,600 | $512,450 – $768,700 | $256,225 – $384,350 | $256,200 – $640,600 |
| 37% | $640,600 and above | $768,700 and above | $384,350 and above | $640,600 and above |
The standard deduction comes first
Before any bracket applies, you subtract your deduction. For 2026:
- Single: $16,100
- Married filing jointly: $32,200
- Married filing separately: $16,100
- Head of household: $24,150
Roughly nine in ten filers take the standard deduction rather than itemising, because it now exceeds what most households could itemise.
Worked example: $120,000, single filer
This is the calculation that dispels the bracket myth. Gross pay of $120,000, minus the $16,100 standard deduction, leaves $103,900 of taxable income:
| Rate | Band | Income in band | Tax |
|---|---|---|---|
| 10% | $0 – $12,400 | $12,400 | $1,240 |
| 12% | $12,400 – $50,400 | $38,000 | $4,560 |
| 22% | $50,400 – $105,700 | $53,500 | $11,770 |
| Total federal income tax | $17,570 | ||
This filer is "in the 24% bracket" — that is their marginal rate, and it is what an extra dollar of salary would be taxed at. But their effective federal rate is only 14.6% of gross pay. The 24% applies to the last $53,500 and nothing more.
The practical consequence: a raise can never reduce your take-home pay. Moving into a higher bracket only means the portion above the threshold is taxed more heavily. You keep more in absolute terms, always.
What the brackets do not include
Federal income tax is only part of your withholding. On top of the figures above you also pay Social Security and Medicare — 7.65% combined for most earners, applied to gross wages with no standard deduction — plus any state and local income tax. Your true marginal rate is all of these stacked together, which is the figure the calculator reports.
