Colorado tax rules to know
Key points from our 2026 Colorado data, compiled from the official sources listed at the end of this page:
- Flat 4.4% of Colorado taxable income, which starts from FEDERAL taxable income (so the 2026 federal standard deduction shown here - $16,100 single, $32,200 MFJ, $24,150 HOH - is already built into the base), then Colorado additions and subtractions apply.
- The rate can be temporarily lowered for a tax year when a large TABOR revenue surplus triggers the statutory rate-reduction mechanism (e.g., 4.25% for 2024; 4.4% for 2025). For 2026 the Department of Revenue's 2026 withholding worksheet (DR 1098) uses 4.40%, no reduction had been announced when this was checked, and the 2026 legislative session did not change the rate; any 2026 temporary reduction would depend on the FY 2025-26 TABOR surplus certified in the fall of 2026.
- High-income deduction limit: if AGI exceeds $300,000, federal itemized or standard deductions above $1,000 (single) or $2,000 (joint) must be added back for tax years 2026 and later (the limit was $12,000 / $16,000 for 2023-2025).
- Overtime: for 2026 and later, any federal deduction for qualified overtime compensation must be added back on the Colorado return. No addback is required for the federal qualified tips deduction.
- The federal qualified business income (QBI) deduction must be added back by single filers with AGI over $500,000 and joint filers with AGI over $1,000,000 (made permanent by HB25B-1001).
- Itemizers must add back state income taxes deducted on the federal return. Colorado offers subtractions for Social Security and pension income (age-based limits).
Local income tax: No percentage-based local income tax, but five cities levy small flat monthly Occupational Privilege Taxes on people who work there: Denver $5.75/month employee share (if earning at least $500/month in Denver) plus $4/month employer; Aurora $2, Greenwood Village $2, Glendale $5 and Sheridan $3 per month employee share.

Is this Colorado tax estimate exact?
It is an estimate. We apply Colorado’s 2026 brackets, standard deduction, exemptions and credits to your income, starting from federal taxable income. We do not model every Colorado subtraction, credit or phase-out, or local income taxes, and federal figures leave out the AMT and the QBI deduction. Use it for planning and check your actual return or Colorado’s tax agency for final numbers.
