2026 federal income tax brackets (single filers)
The US uses a progressive marginal tax system. Only the income within each bracket is taxed at that rate — not your entire income. This is commonly misunderstood. A raise never results in less take-home pay. The 2026 brackets reflect IRS inflation adjustments from Rev. Proc. 2025-32.
| Variable | Meaning |
|---|---|
| 10% | Income $0 – $12,400 |
| 12% | Income $12,401 – $50,400 |
| 22% | Income $50,401 – $105,700 |
| 24% | Income $105,701 – $201,775 |
| 32% | Income $201,776 – $256,225 |
| 35% | Income $256,226 – $640,600 |
| 37% | Income above $640,600 |
Federal tax calculator example: $75,000 salary, single filer, 2026 standard deduction
- 01Gross income: $75,000. Standard deduction 2026: $16,100. Taxable income: $58,900.
- 0210% on first $12,400 = $1,240.
- 0312% on $12,401–$50,400 ($38,000) = $4,560.
- 0422% on $50,401–$58,900 ($8,500) = $1,870.
- 05Total federal tax = $1,240 + $4,560 + $1,870 = $7,670.
Result
Total federal tax: $7,670. Effective rate: 10.2%. After-tax income: $67,330. Marginal (top) bracket: 22%. (Lower than 2024 due to higher 2026 standard deduction of $16,100 vs $14,600.)
What affects how much income tax you owe?
Filing status
Married Filing Jointly has wider bracket thresholds — the 22% bracket starts at $100,801 for MFJ vs $50,401 for single filers in 2026.
Standard vs itemized deductions
The 2026 standard deduction is $16,100 (single) or $32,200 (married). Itemize only if mortgage interest, state taxes (up to $40,400 SALT cap for 2026), and charitable giving exceed those amounts.
Pre-tax contributions
Every dollar contributed to a traditional 401k or HSA reduces your taxable income. A $10,000 401k contribution saves $2,200 in tax at the 22% bracket.
Capital gains income
Long-term capital gains are taxed at 0%, 15%, or 20% — separate from ordinary income brackets. Short-term gains are taxed as ordinary income.
Self-employment income
Self-employed individuals pay an additional 15.3% self-employment tax on net earnings, though half is deductible before computing income tax.
State income tax
This calculator covers federal tax only. State rates range from 0% (TX, FL, WA) to 13.3% (CA). Add state tax for total tax burden.
Tips and things to know
- ✓Your marginal rate is not your effective rate. Someone in the 22% bracket typically has a 10–14% effective federal rate in 2026 after the higher standard deduction.
- ✓Max out your 401k ($23,500 in 2026, or $31,000 if age 50+) before calculating taxes — the deduction can drop you into a lower marginal bracket.
- ✓The 2026 standard deduction is $16,100 for single filers — $1,500 higher than 2024. Most Americans are better off taking it than itemizing.
- ✓If you owe taxes every April, increase your W-4 withholding or make quarterly estimated payments to avoid underpayment penalties.
- ✓Self-employed? Deduct half of self-employment tax, health insurance premiums, and home office before calculating income tax.
