Effective Federal Tax Rate by Income (2026)
A single filer earning $100,000 pays an effective federal income tax rate of about 13.2% in 2026 — well below the 22% bracket they sit in. Your effective rate (total tax ÷ income) is always lower than your top bracket, because your first dollars are taxed at 10% and 12%.
We ran every income level through the 2026 brackets and standard deduction to show what share of income actually goes to federal income tax, by filing status. (Federal income tax only — no credits, payroll tax or state tax.)
Effective federal tax rate by income (2026)
Effective rate = total federal income tax ÷ gross income, after the standard deduction. Each figure is computed from the 2026 brackets, not estimated.
| Gross income | Single | Married filing jointly | Head of household |
|---|---|---|---|
| $25,000 | 3.6% | 0% | 0.3% |
| $50,000 | 7.6% | 3.6% | 5.5% |
| $75,000 | 10.2% | 6.2% | 7.7% |
| $100,000 | 13.2% | 7.6% | 9.6% |
| $150,000 | 16.5% | 10.2% | 14.0% |
| $200,000 | 18.4% | 13.2% | 16.5% |
| $300,000 | 22.7% | 16.5% | 21.2% |
| $500,000 | 27.6% | 20.5% | 26.7% |
| $1,000,000 | 32.0% | 28.0% | 31.5% |
Why your effective rate is lower than your bracket
Take a single filer earning $100,000. After the $16,100 standard deduction, $83,900 is taxable — and it fills the brackets from the bottom up, totalling $13,170. That's a 13.2% effective rate, even though the last dollar sits in the 22% bracket:
| Slice of taxable income | Rate | Tax |
|---|---|---|
| First $12,400 | 10% | $1,240 |
| $12,400 – $50,400 | 12% | $4,560 |
| $50,400 – $83,900 | 22% | $7,370 |
| Total on $83,900 taxable | — | $13,170 |
How we calculated this
For each income we subtract the 2026 standard deduction ($16,100 single, $32,200 joint, $24,150 head of household), run the result through the 2026 federal brackets, and divide the tax by gross income. These are federal income tax only — they exclude tax credits (which lower your real rate), payroll/FICA tax (which raises it), and state income tax.

What is an effective tax rate?
Your effective (or average) tax rate is your total tax divided by your total income. It is always lower than your marginal rate — the bracket your last dollar falls into — because your earlier income is taxed at lower rates first.
What is the effective federal tax rate at $100,000 of income?
In 2026 it is about 13.2% for a single filer and 7.6% for married filing jointly — federal income tax only, after the standard deduction. That is well below the 22% bracket a $100,000 single filer sits in.
Why is my effective tax rate lower than my bracket?
Brackets are marginal: only the income above each threshold is taxed at the higher rate. Your first dollars are taxed at 10% and 12%, so the average across all your income is lower than the top rate you reach.
Does this include payroll and state tax?
No. These figures are federal income tax only. Social Security and Medicare (FICA, 7.65%) and any state income tax are charged on top, while tax credits would lower your real effective rate.
Is the effective tax rate the same as the average tax rate?
Yes. "Effective" and "average" tax rate are two names for the same figure — total tax divided by total income.
