How Colorado taxes your paycheck
Colorado levies a flat 4.4% state income tax on federal taxable income (with state-specific adjustments), governed by the TABOR constitutional amendment that periodically reduces the rate and issues refunds when state revenue exceeds a fiscal cap.
Five Colorado cities—Denver, Aurora, Glendale, Greenwood Village, and Sheridan—levy a flat-dollar Occupational Privilege Tax (Denver charges employees $5.75/month) on workers earning more than the local threshold, withheld directly by employers.
Local context: Major employment hubs in Colorado include Denver, Colorado Springs, Aurora, Fort Collins. Colorado's flat 4.4% rate is set by the state constitution's TABOR amendment, which has triggered automatic temporary rate reductions and TABOR refunds in years when state revenue exceeds the population-plus-inflation cap.
Local tax note: Denver, Aurora, Greenwood Village, Sheridan, and Glendale levy an Occupational Privilege Tax (OPT) of $2–$5.75 per month on employees earning above a threshold; Denver's is $5.75 employee + $4.00 employer per month.
