Quick answer

The marginal rate applies only to income above the bracket threshold, so a raise never reduces take-home pay — only the extra dollars are taxed higher.

Marginal tax = extra income × bracket rate

Frequently asked questions

Can a raise leave me worse off?

Not from income tax — only the income above a threshold is taxed at the higher rate. Benefit cliffs and student loan thresholds are the real risks.

What is the difference between marginal and effective rate?

Marginal is the rate on your next dollar; effective is total tax ÷ total income, and it is always lower.
