Abstract of Assessment

The Abstract of Assessment system is an integrated Web-based application that allows county assessors to enter, edit, and view the assessment data required by C.R.S. 39-5-123. Each county assessor has been assigned a user ID and password for the system, which will permit them to work with only their own county records.

Submitting Data Files
If you prefer to submit your data electronically, you may do so by following the file layout specification. This specification was jointly developed by the Department of Local Affairs, county assessors, and software vendors. The resulting files should be e-mailed. We will import the files into the database and return a report showing any problems. Within a business day following your submission, you can view, edit, and print your data using the online application.
