A raise cannot leave you worse off
Only the income above a bracket threshold is taxed at the higher rate. A single filer earning $119,000 pays $17,629 in federal tax for 2025; at $120,000 they pay $17,867. The extra $1,000 costs $238, so $762 is kept, even though the raise crossed from the 22% bracket into the 24% one.
The belief that a raise can push you into a higher bracket and leave you with less money is the most durable misconception in personal tax. It is intuitive, it is repeated confidently in offices every year, and it is arithmetically impossible under a progressive bracket system.
The actual arithmetic
| Gross income | Taxable income | Federal tax | Marginal rate | Effective rate |
|---|---|---|---|---|
| $119,000 | $103,250 | $17,629 | 22% | 14.81% |
| $120,000 | $104,250 | $17,867 | 24% | 14.89% |
The raise is $1,000 and the extra tax is $238. Of that raise, $100 fell below the $103,350 threshold and was taxed at 22%, and the remaining $900 was taxed at 24%. Twenty-two plus two hundred and sixteen is two hundred and thirty-eight. Nothing is taxed twice and nothing already earned is re-rated.
Notice the effective rate. It moved from 14.81% to 14.89%, which is what "a higher bracket" actually means: eight hundredths of a percentage point on the whole income, not two points.
Where the intuition comes from
It comes from the word bracket doing the wrong work. People picture income falling into a box and the box having a rate. What actually happens is that income is poured through a series of bands, each of which fills before the next begins, and each band keeps its own rate on its own slice forever. Your marginal rate is the rate on the last dollar. Your effective rate is the average across all of them, and it is always lower.
The cases where more income really can cost you
The myth survives partly because a related thing is true. Benefits and credits often phase out at a threshold, and those cliffs can be sharp: losing eligibility for a subsidy, a credit or an income-driven repayment band can cost more than the raise. That is a benefits cliff, not a tax bracket, and it is worth checking separately.
- Premium tax credits, which taper with income.
- Income-driven student loan repayment, where the payment is a share of discretionary income.
- Means-tested benefits with a hard eligibility line rather than a taper.
