What is Tax bracket?

The rate applied to the top slice of your income.

Last updated

Most modern tax systems are progressive: different income slices are taxed at different rates. Being 'in' the 22% bracket doesn't mean paying 22% on all your income — only on the portion above the previous bracket's threshold.

Understanding your marginal rate helps size decisions like traditional vs Roth contributions, whether to take a bonus this year or next, and how much a deduction is worth.

Frequently asked questions

Marginal vs effective rate?

Marginal is the rate on your next dollar. Effective is total tax divided by total income — always lower than the marginal rate in a progressive system.
