Colorado's flat 4.40% rate
Colorado applies a single flat income tax rate of 4.40% rather than graduated brackets, and its base conforms to federal taxable income. That makes the state line straightforward: the same 4.40% applies to a low earner and a high earner alike, sitting on top of the 2026 federal income tax, Social Security, and Medicare lines.
Because the rate is flat, the state's share of a raise stays constant at 4.40% no matter how much you earn — unlike graduated states where higher income meets higher rates. This estimate is a 2026 figure and does not model Colorado-specific credits, deductions beyond the federal base, or local taxes; it is not tax advice.
Questions
- Is Colorado's income tax really one flat rate?
- Yes. Colorado taxes individual income at a single flat 4.40% rate instead of graduated brackets, on a base that conforms to federal taxable income. The same rate applies regardless of how much you earn.
- How does a flat rate change a raise versus a bracketed state?
- Under Colorado's flat 4.40%, the state takes the same percentage of every additional dollar. In a graduated state, extra income can fall into a higher bracket, so the marginal state rate rises as you earn more.
