How Colorado taxes income
Colorado is a flat-tax state pegged to your federal taxable income, and TABOR forces the state to hand surpluses back — the rate was temporarily cut to 4.25% in 2024 for exactly that reason. When revenue runs hot, your rate can drop without anyone passing a tax cut.
| Taxable income (single) | Rate |
|---|---|
| $0+ | 4.4% |
Deduction applied before state tax (single filer): $16,100.
