How tax brackets actually work

Fix the single most common misunderstanding in American personal finance.

The biggest tax myth in existence: 'I don't want that raise, it'll push me into a higher bracket and I'll take home less.' This is never true. Ever. It's not how brackets work.

Marginal vs. effective

Tax brackets are marginal, which means the higher rate only applies to the dollars inside that bracket. Your first $11,600 is taxed at 10%. The next chunk at 12%. The next at 22%. And so on. Moving up a bracket only affects your last dollar, not your first.

A concrete case

Say you earn $50,000 and the 22% bracket starts at $47,150. Only the $2,850 above $47,150 is taxed at 22%. Everything below it is still taxed at the lower rates. Your 'effective' tax rate is much lower than your top bracket — usually by 5–10 percentage points.

Why this matters

Because people make real decisions — turning down raises, avoiding overtime, declining promotions — based on this misunderstanding. Every extra dollar of income always nets you more after-tax money. It just might net you less than you expected. Never less than zero.

Two useful numbers

Your marginal rate is the rate on your next dollar — useful for deciding if another dollar is worth earning. Your effective rate is your total tax divided by total income — useful for understanding what you actually pay. They are very different numbers.
