Federal income tax is not one flat percentage. For 2026 there are seven rates, from 10% to 37%, and each one applies only to the slice of income inside its bracket. So the share of your income that actually goes to federal income tax is much lower: about 8.4% for a single filer earning $60,000 and 13.2% at $100,000.
The gap between your "bracket" and what you really pay causes most of the confusion. Below are the 2026 brackets, real percentages by salary, the math, and IRS data on what Americans actually pay.
What are the federal income tax rates for 2026?
The seven rates are 10%, 12%, 22%, 24%, 32%, 35% and 37%. The rates did not change for 2026, but the income ranges rose with inflation. The brackets apply to taxable income, which is what is left after you subtract the standard deduction: $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household.
| Rate | Single | Married filing jointly |
|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 |
| 22% | $50,401 – $105,700 | $100,801 – $211,400 |
| 24% | $105,701 – $201,775 | $211,401 – $403,550 |
| 32% | $201,776 – $256,225 | $403,551 – $512,450 |
| 35% | $256,226 – $640,600 | $512,451 – $768,700 |
| 37% | Over $640,600 | Over $768,700 |
Long-term capital gains are taxed separately, at 0%, 15% or 20%, according to IRS Topic 409. Short-term gains are taxed at the ordinary rates above.
What percentage of my income goes to federal income tax?
This table answers the question most people are really asking. It shows federal income tax as a share of gross wages for 2026, assuming the standard deduction and no credits or pre-tax savings.
| Gross income | Single: tax | Single: % of income | Single: bracket | Married joint: tax | Married joint: % of income | Married joint: bracket |
|---|---|---|---|---|---|---|
| $30,000 | $1,420 | 4.7% | 12% | $0 | 0.0% | None |
| $50,000 | $3,820 | 7.6% | 12% | $1,780 | 3.6% | 10% |
| $75,000 | $7,670 | 10.2% | 22% | $4,640 | 6.2% | 12% |
| $100,000 | $13,170 | 13.2% | 22% | $7,640 | 7.6% | 12% |
| $150,000 | $24,734 | 16.5% | 24% | $15,340 | 10.2% | 22% |
| $200,000 | $36,734 | 18.4% | 24% | $26,340 | 13.2% | 22% |
| $300,000 | $68,134 | 22.7% | 35% | $49,468 | 16.5% | 24% |
| $500,000 | $138,134 | 27.6% | 35% | $102,608 | 20.5% | 32% |
The percentage you pay is always well below your bracket. Joint filers pay a smaller share at the same household income, because their brackets and standard deduction are twice as wide.
Effective tax rate vs. marginal tax rate: what's the difference?
Your marginal rate is the rate on your last dollar of taxable income. That is your "tax bracket." Your effective rate is your total federal income tax divided by your income. It is the real percentage you pay. Here is how one salary produces both.
- 10% on the first $12,400
- $1,240
- 12% on the next $38,000
- $4,560
- 22% on the last $33,500
- $7,370
- Total federal income tax
- $13,170
- Marginal rate (bracket)
- 22%
- Effective rate on taxable income
- 15.7%
- Effective rate on gross income
- 13.2%
What percentage of income do Americans actually pay in federal tax?
On average, about 14.1% of adjusted gross income, according to the latest IRS Statistics of Income data, which covers tax year 2023. The share rises steeply with income:
| Group | Income needed to be in group (AGI) | Average income tax rate |
|---|---|---|
| Top 1% | $675,602 or more | 26.3% |
| Top 10% | $187,608 or more | 20.9% |
| Top 50% | $53,801 or more | 15.6% |
| Bottom 50% | Under $53,801 | 3.7% |
| All filers | — | 14.1% |
Even the top 1% average about 26%, well below the 37% top rate, because much of their income is taxed in lower brackets or at capital-gains rates.
What percentage of my paycheck is withheld for federal tax?
Two federal taxes come out of a paycheck, and only one of them is income tax. Social Security and Medicare (FICA) take a flat 7.65% of wages, with Social Security stopping after $184,500 in 2026. Your federal income tax withholding is set by your W-4 and roughly tracks the effective rates above.
So a $60,000 single filer has about 8.4% withheld for income tax plus 7.65% for FICA, or about 16.0% in total federal taxes. Self-employed people pay both halves of FICA, a 15.3% self-employment tax, on top of income tax. For the full pay-stub breakdown, including state tax, see how much tax is taken out of a paycheck, or plug your own salary into our paycheck tax calculator. If your withholding looks too high or too low, our guide on how much federal tax to withhold walks through the W-4.
What lowers your federal income tax percentage?
- Pre-tax retirement savings. Traditional 401(k) contributions, up to $24,500 in 2026, come off the top of your taxable income. A $100,000 single filer who puts in $10,000 cuts federal income tax from $13,170 to $10,970, or from 13.2% to 11.0% of salary. That money is taxed later, when you take it out; see how 401(k) withdrawals are taxed.
- HSA contributions and other pre-tax benefits, such as most employer health premiums.
- Tax credits. Credits subtract from the tax itself, not from income. A married couple earning $100,000 owes $7,640 before credits. With two children under 17, the $2,200-per-child credit cuts that to $3,240, or 3.2% of income.
- Itemizing, if your deductions beat the standard deduction.
- New 2025–2028 deductions for qualified tips, overtime, car-loan interest and people 65 or older.
What are the federal income tax rates for 2027?
The IRS published the 2027 numbers on Nov. 5, 2026, in IR-2026-133. The seven rates stay the same. The brackets rise about 3%, and the standard deduction goes to $16,600 for single filers and $33,200 for married couples filing jointly ($24,925 for heads of household).
| Rate | Single | Married filing jointly |
|---|---|---|
| 10% | $0 | $0 |
| 12% | $12,800 | $25,600 |
| 22% | $52,025 | $104,050 |
| 24% | $109,125 | $218,250 |
| 32% | $208,325 | $416,650 |
| 35% | $264,550 | $529,100 |
| 37% | $661,375 | $793,650 |
The bottom line
The honest answer to "what percentage is federal income tax" is two numbers. Your bracket tells you what the next dollar costs. Your effective rate tells you what you really pay, and in our table it stays under 19% for every income up to $200,000. To find yours, divide the "total tax" line on last year's Form 1040 by your total income.
