Understanding Federal Income Tax Brackets for 2025-26
The United States uses a progressive tax system, meaning your income is taxed at different rates depending on how much you earn. For tax year 2025 (filed in 2026), the IRS has adjusted all seven tax brackets for inflation. The rates remain at 10%, 12%, 22%, 24%, 32%, 35%, and 37%, but the income thresholds have increased slightly.
| Tax Rate | Single Filers | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0 - $11,600 | $0 - $23,200 | $0 - $16,550 |
| 12% | $11,601 - $47,150 | $23,201 - $94,300 | $16,551 - $63,100 |
| 22% | $47,151 - $100,525 | $94,301 - $201,050 | $63,101 - $100,500 |
| 24% | $100,526 - $191,950 | $201,051 - $383,900 | $100,501 - $191,950 |
| 32% | $191,951 - $243,725 | $383,901 - $487,450 | $191,951 - $243,700 |
| 35% | $243,726 - $609,350 | $487,451 - $731,200 | $243,701 - $609,350 |
| 37% | Over $609,350 | Over $731,200 | Over $609,350 |
💡 Pro Tip: Understanding Marginal vs. Effective Tax Rate
Your marginal tax rate is the rate you pay on your last dollar of income, while your effective tax rate is your total tax divided by your total income. Use our tax bracket calculator to see both rates.
Standard Deduction Changes for 2025
The standard deduction has increased for 2025, reducing your taxable income automatically if you don't itemize deductions:
- Single filers: $14,600 (up from $14,600 in 2024)
- Married filing jointly: $29,200 (up from $29,200 in 2024)
- Head of household: $21,900 (up from $21,900 in 2024)
State Income Tax Considerations
While federal taxes apply to all Americans, state income taxes vary significantly. Nine states have no income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Other states range from California's top rate of 13.3% to North Dakota's 2.9%.

Special Tax Situations
Self-Employment Tax
If you're self-employed, you pay both the employer and employee portions of Social Security and Medicare taxes, totaling 15.3% on your net earnings. This is in addition to regular income tax. Use our self-employment tax calculator to see your total tax obligation.
Bonus and Commission Income
Bonuses are typically taxed at a flat 22% federal rate (or 37% if over $1 million annually), plus state taxes. However, your final tax obligation depends on your total annual income. Our bonus tax calculator shows both withholding and actual tax owed.
Capital Gains Tax
Long-term capital gains (assets held over one year) are taxed at 0%, 15%, or 20% depending on your income level. Short-term gains are taxed as ordinary income. Calculate your capital gains tax with our capital gains calculator.
