The Colorado Legislature and Governor Polis recently enacted changes to laws to accommodate property tax relief, which will delay Colorado counties certifying their tax roll. The new tax roll deadline is January 24, 2024, which is two weeks later than previous years.  

This new deadline allows taxing authorities sufficient time to certify their mill levies and give County Assessors more time to compile newly required data, which subsequently delays the tax roll certification.

The changes do not alter the first-half payment due date for property taxes which is February 29, 2024, due to the 2024 Leap Year.

The Colorado Legislature did not adjust this first half deadline, at the request of special districts like fire departments, school districts, health districts, hospitals, and other public entities. These districts needed to ensure that they would receive early spring tax revenues from County Treasurers on the same schedule as previous years, in order to have sufficient revenue to continue to operate.

Once the tax roll process is complete property owners will receive their statements which takes about two weeks by mail. Property owners can also sign up for E-notices, which saves time, postage and paper.
