Colorado Tax & Salary Calculators (2026)
Everything you need to work out pay and tax as a Colorado resident in 2026, in one place. Colorado applies a flat 4.40% income tax after a $16,100 state standard deduction. Federal income tax and FICA (6.2% Social Security up to $184,500 plus 1.45% Medicare) apply on top, identically in every state — the Colorado layer is what makes your net pay different from a neighbour's.
Colorado's flat tax rate is set in the state constitution — voters must approve any increase, which is why it keeps drifting downward. Cost of living in Colorado sits at index 105 (US average = 100), median household income is $87,598, and a one-bedroom apartment in Denver rents for around $1,750 per month. The local economy leans on tech, aerospace, and energy.

Commuting and remote work across Colorado lines
Colorado has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
If you work remotely for an out-of-state employer, the state where you physically sit normally has the first claim on your wages, while your employer may still be required to register for Colorado withholding. Keep a day-count record whenever you split the year between Colorado and Wyoming.
