What your salary leaves after taxes in Colorado (2026)
Colorado's flat 4.4% income tax applies after a standard deduction that matches the federal amount ($16,100 single / $32,200 married). No local income taxes exist anywhere in the state. And the TABOR amendment means that when state revenue exceeds constitutional limits, you get a refund check.

| $75,000 | $7,670 | $5,738 | $2,592 | $59,001 | 21.3% |
| $100,000 | $13,170 | $7,650 | $3,692 | $75,488 | 24.5% |
Single filer, standard deduction $16,100, 2026 federal brackets. TABOR refund not included in take-home.
TABOR: Colorado's built-in tax-refund mechanism
Colorado's Taxpayer's Bill of Rights (TABOR) caps state revenue growth to population growth plus inflation. When collections exceed the cap, the state must return the surplus to taxpayers. In recent fiscal years, TABOR refunds have ranged from around $400 to over $800 per adult filer — effectively reducing the 4.4% rate by a fraction of a point in practice. The refund amount varies each year and is typically claimed on your state tax return.

Colorado versus other Western flat-tax states
Among Western flat-tax states, Colorado's 4.4% falls between Arizona's 2.5% and Utah's 4.5%. On $100,000, you keep $75,488 in Colorado versus $77,082 in Arizona (the lowest-tax option) and $75,404 in Utah (nearly identical). All three use a federal-matching standard deduction, making the rate the main differentiator. Colorado's TABOR refunds and absence of local income taxes further narrow the gap with Utah.

What is TABOR and do I get a refund?

Does Colorado have local income taxes?
No. Colorado does not levy any local or city income taxes. The flat 4.4% state rate is the only income tax on wages. Denver and other cities collect sales taxes and some occupational privilege taxes (a small flat fee), but no percentage-based income tax.
