Understanding your federal income tax bill helps you plan withholding, estimate refunds, and avoid surprises at filing time. This estimator applies the current tax brackets and standard deduction to your income to approximate what you will owe.
How progressive tax brackets work
The U.S. uses a progressive system, meaning different portions of your income are taxed at different rates. Being in the 22% bracket does not mean all your income is taxed at 22% — only the dollars above that bracket's threshold are. Your effective tax rate, the average across all your income, is always lower than your top marginal rate.
The role of the standard deduction
Before brackets apply, you subtract the standard deduction from your income. For 2026 it is $16,100 for single filers and $32,200 for married couples filing jointly. Only the amount above the deduction — your taxable income — is subject to tax, which is why someone earning $16,000 as a single filer owes little to no federal income tax.
A worked example
A single filer earning $70,000 in 2026 subtracts the $16,100 standard deduction for $53,900 taxable income. The tax is calculated in layers — 10% on the first $12,400, 12% on the next $38,000, 22% on the last $3,500 — producing a total federal tax of about $6,570, an effective rate near 9.4% of gross income even though the top marginal rate is 22%.
Reducing your tax bill
- Contributing to a traditional 401(k) or IRA lowers taxable income dollar for dollar.
- Tax credits — unlike deductions — reduce your tax directly; the Child Tax Credit and education credits can be substantial.
- Itemize instead of taking the standard deduction only if your deductible expenses (mortgage interest, state taxes, charity) exceed it.
- This estimate covers federal tax only; add state income tax where applicable for your full picture.
2026 federal tax brackets
| 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 |
Estimated federal tax at common incomes (single filer)
The table applies the 2026 standard deduction of $16,100 and the brackets above to wage income, with no credits. It shows how the effective rate, your total tax divided by income, stays well below your top bracket.
| Gross income | Taxable income | Federal tax | Effective rate | Marginal rate |
|---|---|---|---|---|
| $40,000 | $23,900 | $2,620 | 6.6% | 12% |
| $60,000 | $43,900 | $5,020 | 8.4% | 12% |
| $75,000 | $58,900 | $7,670 | 10.2% | 22% |
| $100,000 | $83,900 | $13,170 | 13.2% | 22% |
| $150,000 | $133,900 | $24,734 | 16.5% | 24% |
| $250,000 | $233,900 | $51,304 | 20.5% | 32% |
Married couples filing jointly see an identical pattern at double the income: because the 2026 joint brackets and standard deduction are exactly twice the single amounts through the 32% bracket, a couple earning $150,000 owes about $15,340 (10.2%), the same rate as a single person earning $75,000.
Credits versus deductions
A deduction lowers taxable income, so its value depends on your bracket: a $1,000 deduction saves $220 for someone in the 22% bracket. A credit lowers the tax bill dollar for dollar, so a $1,000 credit saves $1,000. Common credits include the Child Tax Credit, education credits, and the Saver’s Credit for lower-income retirement savers. Because this estimator focuses on brackets and deductions, subtract any credits you qualify for from the result.
- Pre-tax 401(k), traditional IRA (if eligible), and HSA contributions all reduce taxable income.
- Itemize only if mortgage interest, state and local taxes (capped at $40,400 for most filers in 2026), and charitable gifts exceed your standard deduction.
- Remember payroll taxes: Social Security and Medicare are separate from the income tax shown here.
A common myth: “A raise will push me into a higher bracket and I will take home less”
Because the U.S. uses marginal brackets, only the dollars above each threshold are taxed at the higher rate. A single filer whose income rises from $65,000 to $68,000 crosses into the 22% bracket, but only the portion of taxable income above $50,400 is taxed at 22%; everything below stays at 10% and 12%. A raise always increases after-tax income from federal income tax alone. The rare exceptions come from benefit phase-outs and credit cliffs, not from the brackets themselves, which is another reason to check eligibility for credits such as the Earned Income Tax Credit when your income changes.
