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 2026 residential rules: 7.05% on school-district mills, and 6.8% on all other mills after the 10% adjustment on the first $700,000 in actual value. It is a planning figure. A real bill depends on the parcel's exact tax area and exemptions.
