Standard deduction and exemption in Colorado
The 2026 standard deduction is $16,100 for single filers and $32,200 for married filing jointly. In Colorado, that means the first $16,100 of a single filer's pay is taxed at zero before the schedule even starts.
Worked example: the brackets on a $75,000 salary
A single filer earning $75,000 in Colorado first removes the standard deduction, leaving $58,900 of taxable income. Each bracket then takes its slice:
| Bracket range | Income in bracket | Rate | Tax |
|---|---|---|---|
| $0 and up | $58,900 | 4.4% | $2,592 |
Total Colorado income tax: $2,592, an effective rate of 3.46% of gross pay. The marginal rate, the rate on the next dollar Colorado taxes, is 4.4%; a raise that crosses into that bracket pays 4.4% only on the dollars above the line, never on the whole salary.
