Property tax snapshot
Typical property tax in Conejos County
The average total mill levy across Conejos County was about 75.3 mills for tax year 2023 — below the statewide average of about 81 mills. On a $500,000 home, that comes to roughly $2,467 a year, using Colorado's 2026 residential rules: 7.05% on school mills, and 6.8% on the rest after the local actual-value adjustment.
This is the county average across all tax areas. Your parcel's actual mill levy depends on its exact tax area — a metro or special district can add many mills on top — so confirm the real number with the county assessor.
Sales tax: the state charges 2.9% and Conejos County adds no county sales tax — cities and special districts still can. See Colorado sales tax rates ->
