What Are Tax Brackets?
Quick Answer
Tax brackets are income ranges that are each taxed at a different rate under the federal progressive tax system. The United States has seven federal tax brackets in 2025: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The most common misconception is that earning more money pushes ALL your income into a higher bracket. In reality, only the dollars within each bracket are taxed at that bracket's rate.

For married filing jointly, the bracket thresholds are roughly double. Use the married calculator to see joint filing brackets in action.
How Tax Brackets Actually Work
Think of tax brackets as a staircase. Your income fills up each step before spilling into the next. When people say "I'm in the 22% bracket," they mean their highest dollars are taxed at 22% — not all of their income.
This is the difference between your marginal tax rate (the rate on your last dollar) and your effective tax rate (the average rate across all your income).
Real Example With Actual Numbers
Jessica is single and earns $80,000 in gross income. After the standard deduction of $15,000 in 2025, her taxable income is $65,000. Here is how the brackets apply:
| Bracket | Income in Bracket | Tax |
|---|---|---|
| 10% | $11,925 | $1,192.50 |
| 12% | $36,550 ($48,475 - $11,925) | $4,386.00 |
| 22% | $16,525 ($65,000 - $48,475) | $3,635.50 |
| Total | $65,000 | $9,214.00 |
Jessica's marginal rate is 22%, but her effective federal tax rate is only about 14.2% ($9,214 / $65,000). That is why it never hurts to earn more money — a raise will never result in less take-home pay. You can verify these numbers using the SalaryHog calculator.
Why This Matters for Your Paycheck
Understanding brackets helps with:
- Evaluating raises: If you earn $100,000 and get a $5,000 raise, only that $5,000 is taxed at your marginal rate — not your entire salary. See how raises are taxed.
- Retirement planning: 401(k) contributions reduce your taxable income, potentially keeping you in a lower bracket.
- State comparison: Some states add their own brackets on top. California has rates up to 13.3%, while Texas and Florida have no state income tax at all. Compare states with the relocation tool.
- Filing status: Choosing the right filing status changes which bracket thresholds apply to you.
