How Colorado taxes your paycheck in 2026
Colorado taxes wages at a flat 4.4%, after a $16,100 single-filer standard deduction (the state uses the federal deduction).
Federal deductions are the same everywhere: income tax on your wages after the $16,100 standard deduction (single filers), 6.2% Social Security on the first $184,500 of wages, and 1.45% Medicare on everything.
Colorado's income tax, in context
Colorado taxes income at a flat 4.4% and starts from federal taxable income, so the federal standard deduction flows through automatically. Voters have trimmed the rate twice via ballot measures (from 4.63%), and the state's TABOR amendment periodically refunds surplus revenue to taxpayers rather than letting the rate drift up.
