How Federal Income Tax Brackets Actually Work

The most misunderstood part of taxes: moving into a higher bracket does not tax all your income at that rate. Here is how marginal rates really work.

The big misconception

Many people fear a raise will "push them into a higher bracket" and leave them with less money. That is not how it works. Tax brackets are marginal — only the income within each bracket is taxed at that bracket's rate.

A simple example

Suppose the 12% bracket ends at $47,150 and the 22% bracket begins above it. If you earn $50,000, only the ~$2,850 above $47,150 is taxed at 22%. The rest is taxed at the lower rates. A raise always leaves you with more take-home pay.

Marginal vs. effective rate

Your marginal rate is the rate on your last dollar (your top bracket). Your effective rate is total tax ÷ total income, and it is always lower. Someone "in the 22% bracket" might have an effective rate closer to 13%.
