How marginal tax brackets actually work
Tax brackets are marginal, not flat — only the income inside each band is taxed at that band's rate, not your whole income at the top rate. A common misread is thinking a raise that pushes you into a higher bracket lowers your take-home pay overall; it doesn't, because the higher rate only applies above the threshold.
| Taxable income band | Rate | Tax on that band |
|---|---|---|
| First $10,000 | 10% | $1,000 |
| Next $30,000 (to $40,000) | 12% | $3,600 |
| Next $10,000 (to $50,000) | 22% | $2,200 |
On $50,000 total income, the effective tax rate here is $6,800 ÷ $50,000 = 13.6% — well below the 22% marginal rate on the last dollar earned. Every calculator on this page applies its jurisdiction's real bracket structure the same way.
