Colorado charges a flat 4.4% on taxable income, which starts from federal taxable income (wages minus the federal standard deduction). On $65,000 single, that is about $2,150 of Colorado tax — an effective rate of about 3.3%. Rates: Colorado Department of Revenue. State credits are not modeled.
Colorado has phased in exemptions for Social Security and certain retirement income for many taxpayers, subject to income limits. This wage-focused calculator does not model those retirement exclusions.
Wyoming has no broad state wage income tax in this model. Utah uses a flat rate with a different base structure. At the same gross salary, compare Colorado, Utah, and Wyoming on each state page to see federal + state + FICA side by side.
Colorado starts from federal taxable income, so the federal standard deduction ($16,100 single / $32,200 married joint in 2026) carries through to the state return. The calculator applies 4.4% to that amount; Colorado additions, subtractions, and credits are not modeled.
