How the $13,170 is calculated (single)
$100,000 minus the $16,100 standard deduction leaves $83,900 of taxable income. Each slice is taxed at its own rate:
| Bracket | Rate | Income taxed | Tax |
|---|---|---|---|
| $0 – $12,400 | 10% | $12,400 | $1,240.00 |
| $12,400 – $50,400 | 12% | $38,000 | $4,560.00 |
| $50,400 – $105,700 | 22% | $33,500 | $7,370.00 |
You have $21,800 of taxable income left before the 24% bracket starts, so a raise or bonus up to that size is still taxed at 22%.
