Colorado property tax deadlines

6 sourced dates. 64 of 64 Colorado counties have at least one.

Colorado sets one calendar for every county in state law (Title 39 of the Colorado Revised Statutes), and the county treasurer collects. Last year's taxes come due January 1. You can pay in full by April 30, or in two halves by the end of February and June 15. A new law moves the value protest deadline from June 8 to June 1 starting in 2027.
