|---|---|---|---|
| $25k | $10,072 | $7,534 | +$2,538 |
| $50k | $20,007 | $14,969 | +$5,038 |
| $100k | $41,190 | $29,839 | +$11,351 |

- Single filer, $200,000 in other taxable income before this vest (2026 federal brackets).

- State and local marginal and withholding rates both modeled at the state's published top marginal individual income-tax rate.
- Payroll (Social Security and Medicare, including Additional Medicare where it applies) withheld and taxed under 2026 thresholds.
