Colorado income tax in 2026
Colorado taxes wages at a flat 4.4% after a standard deduction of $16,100 (single). A flat tax means every additional dollar you earn is taxed at the same state rate, whatever your income.
Worth knowing: The state sales rate is only 2.9%, but local rates roughly triple the total in many areas. TABOR refunds can temporarily lower the income rate.
