Why you don't keep 100% of your raise
Your raise is taxed at your marginal rate — the rate applied to your highest dollars of income. Even though your effective rate (taxes ÷ total income) is lower, each new dollar from your raise is taxed at the top bracket you've reached. For example, if your marginal federal rate is 22.0%, every extra dollar of your raise loses that share to federal taxes alone — before state taxes and FICA. That's why raises always feel smaller than advertised.

Frequently Asked Questions
How much of my raise do I actually keep after taxes?
It depends on your marginal tax rate. For most middle-income workers, you keep between 65% and 80% of a raise after all federal, state, and FICA taxes. Use this calculator to see your exact percentage.
Does a raise push me into a higher tax bracket?
It can, but only the dollars above the new threshold are taxed at the higher rate — not your entire salary. The US uses a progressive marginal system, so crossing a bracket line affects only the raise dollars above that line.
What is the marginal tax rate on a raise?
Your marginal rate is the rate applied to your last (highest) dollars of income. For 2026 Single filers: 10%, 12%, 22%, 24%, 32%, 35%, or 37% for federal, plus state tax and FICA on top.
