Tax Brackets Explained: Marginal vs. Effective Rate
"A raise pushed me into a higher bracket and now I take home less" is one of the most common tax misunderstandings — and it's not how brackets actually work.
Brackets are marginal, not all-or-nothing
Moving into a higher tax bracket only means your next dollar of income (the portion above the bracket threshold) is taxed at the higher rate — not your entire income. Every dollar below that threshold is still taxed at the lower rates that applied to it.
A simplified example
| Income range | Rate on that portion |
|---|---|
| $0 – $11,000 | 10% |
| $11,001 – $44,725 | 12% |
| $44,726 – $95,375 | 22% |
Someone earning $50,000 doesn't pay 22% on all $50,000 — they pay 10% on the first chunk, 12% on the next chunk, and 22% only on the portion above $44,725. (Brackets and thresholds are adjusted periodically; check current figures for the actual numbers in a given year.)
What "effective tax rate" actually means
Your effective rate is your total tax divided by your total income — a blended average across all the brackets your income passed through. It's always lower than your top marginal bracket, often significantly so.
So can a raise ever actually reduce your take-home pay?
In the core federal income tax system, no — a raise can never reduce your after-tax income, since only the additional income is taxed at the higher rate. Where confusion sometimes legitimately arises: certain other benefits (means-tested credits, some employer benefits) can phase out at higher incomes, which is a different mechanism from the tax bracket itself, and can occasionally offset part of a raise — but it's a separate issue from marginal bracket confusion.
Why this matters for real decisions
Understanding this removes a common (but incorrect) reason people hesitate to take a raise or extra income — "it'll just get taxed away" dramatically overstates the actual impact, since only the incremental amount faces the higher rate.

Will a raise ever make my paycheck smaller?
No, under the core marginal tax system a raise can't reduce after-tax income — only the additional income above your current bracket faces the higher rate.
What's the difference between marginal and effective tax rate?
Marginal rate is what applies to your next dollar earned; effective rate is your total tax divided by total income, a blended average that's always lower than your top marginal rate.
