Two Colorado counties, side by side.
Pick any two counties to compare their typical property tax — the average mill levy for tax year 2023 and what it costs on a $500,000 home. Every comparison is a shareable link.
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.
