A tax bracket is a range of income that is taxed at a specific rate under the U.S. federal income tax system.
The system is progressive, meaning higher levels of income are taxed at higher rates—but only the income within each bracket is taxed at that bracket’s rate.
✅ Being in a higher tax bracket does not mean all your income is taxed at that rate.
✅ Key Points to Know
- ✅ Multiple tax brackets apply to most taxpayers
- ✅ Only the portion of income within each bracket is taxed at that rate
- ✅ Tax brackets vary by filing status (Single, MFJ, HOH, etc.)
- ✅ Brackets are adjusted annually for inflation
- ✅ The rate on your last dollar of income is your marginal tax rate
🧠 Important Terms
- Marginal Tax Rate:
The tax rate applied to your highest dollar of income - Effective (Blended) Tax Rate:
Your average tax rate across all brackets
📌 Example — How Tax Brackets Work
📄 Scenario
A taxpayer earns $60,000 (Single filer), with the following brackets:
- 10% on income up to $11,000
- 12% on income from $11,001 to $44,725
- 22% on income from $44,726 to $95,375
🧮 Tax Calculation
- First $11,000 → taxed at 10%
- Next $33,725 → taxed at 12%
- Remaining $15,275 → taxed at 22%
✅ The taxpayer’s marginal tax rate is 22%
✅ Their effective tax rate is lower because income is spread across brackets
🔍 Why This Matters
- Being “in the 22% bracket” does not mean all income is taxed at 22%
- Deductions reduce taxable income, potentially lowering the amount taxed at higher brackets
- Credits reduce tax owed, regardless of bracket
- Understanding brackets helps with tax planning and withholding
