Requirements for Second 2023 Abstract of Assessment - latest update

Hide Featured Image

HB24-1179, 2023 Property Tax Year Updated Abstract has been signed into law by Governor Polis. Thank you to the 62 counties that have completed their updated Abstract of Assessment by the due date of February 20, 2024.

For the remaining 2 counties, please complete an updated Abstract of Assessment by end of Day on Friday, February 23, 2024. The portal will be closed at this time.

The abstract must be filed through the regular county portal that was used last year. County assessors can use the same login information to access the system and submit their data. If a new account needs to be made or you forgot your password, please follow the appropriate link to get assistance from that login page.

The changes resulting from Senate Bill 23B-001 include a reduction in the residential assessment rate from 6.765% to 6.7% and an increase in the residential actual value adjustment from $15,000 to $55,000, or the amount that causes the valuation to be $1,000.

In terms of filling out and submitting the new abstract online, only the assessors’ final values need to be reported. Counties are not required to enter CBOE values on this report.

Ultimately, the updated abstract should reflect what was sent out on the final certifications.  

If you have any questions, please contact Thomas Young,, or Wendy Hernandez, at the Division.
