Understanding Marginal vs. Effective Tax Rates
One of the most common misconceptions about taxes is how tax brackets work. When you move into a higher tax bracket, you don't pay that higher rate on your entire income. Instead, the US uses a progressive tax system.
Your marginal tax rate is the rate paid on your last dollar of income (the highest bracket your income reaches). Your effective tax rate is the actual percentage of your total income paid in taxes. For example, even if your marginal rate is 24%, your effective rate might only be 15% because portions of your income were taxed at lower 10%, 12%, and 22% rates.
2024 US Federal Tax Brackets
For the 2024 tax year (taxes filed in early 2025), the IRS slightly adjusted the tax brackets to account for inflation. The seven federal income tax rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
- Single Filers: The top 37% rate applies to individuals earning over $609,350.
- Married Filing Jointly: The top 37% rate applies to couples earning over $731,200.
