Read these as averages, not verdicts. A higher county average often buys services a lower-levy county doesn't fund. And the average hides a lot: within any county, a home in a metro or special district can pay far more than the average, and a rural parcel far less. Use your county page or the estimator for a closer look, and the assessor for the exact number.

How this is figured

The mill levies are the Colorado Division of Property Taxation's assessed-value-weighted average across every tax area in each county for tax year 2023 (levies certified December 2023, taxes payable in 2024). The example tax applies Colorado's two 2025 residential assessment rates — 7.05% on school-district mills and 6.25% on all other mills — to a $500,000 actual value. It's a planning figure; a real bill depends on the parcel's exact tax area and any exemptions.
