How Income Taxes Work
The U.S. uses a progressive tax system with these key components:
- Taxable Income: Your gross income minus adjustments and deductions
- Tax Brackets: Different portions of your income are taxed at increasing rates
- Filing Status: Single, Married Filing Jointly, Married Filing Separately, or Head of Household
- Tax Credits: Dollar-for-dollar reductions in tax liability
Marginal vs. Effective Tax Rate
Understanding the difference between these two rates is crucial for tax planning:
- Marginal Tax Rate: The rate at which your last dollar of income is taxed. This is the tax bracket percentage you fall into based on your highest income level.
- Effective Tax Rate: The average rate at which your entire income is taxed. This is calculated by dividing your total tax liability by your total taxable income.
Your effective rate is always lower than your marginal rate due to the progressive nature of the tax system, where lower portions of your income are taxed at lower rates.
