Caveats
- Brackets for tax years 2012-2022 were indexed for inflation annually; floor and ceiling amounts changed yearly even when statutory rates did not.
- The top bracket's rate applies only to income above its floor: these are marginal rates, not effective rates, and exclude credits and deductions.
- Tax years 2023-2025 pair a flat rate with a 0.0% bracket below a floor (2025: 5.3% above $4,812 single / $9,623 married).
- Bracket ceilings follow each year's own convention: 2012-2022 print an exclusive upper bound, 2023-2025 an inclusive one, one dollar apart from the next floor.
- Filing-status labels are 'Single' and 'Married' exactly as printed; there is no 'married filing jointly' or separate 'filing separately' schedule.
