Colorado State Income Tax Guide (2026)
Colorado levies a flat 4.4% income tax on all taxable income, applied to federal AGI with minor modifications.
1. Colorado Flat Tax Rate
Colorado applies a single flat income tax rate of 4.4% to taxable income. Unlike progressive states, the same rate applies whether you are an entry-level worker or a high earner, which makes the calculation straightforward.
2. Deductions and Conformance
For 2026, the Colorado standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly. Pre-tax 401(k) contributions, HSA contributions, and employer health premiums reduce your Colorado taxable income.
