Intervening Year (2024)

2024 is an intervening year. Most properties do not change value from a reappraisal year to an intervening year. However, properties with intervening year conditions such as new construction, remodels or additions, change in the use of the land,  or other changes to the property will receive a new value in the intervening year. Additionally, if errors or data corrections were discovered, the property will receive a new value, reflecting those corrections.

The County Treasurer is responsible for mailing tax bills and collection of taxes. In Colorado, property taxes are paid in arrears. Property Tax Notices are a static snapshot of ownership and value as of a certain date at the end of the year.

Questions regarding the payment of taxes please contact the Treasurer's Office 303-528-5222

Assessment Process Overview

The assessment process involves setting standards for fair and equitable values, discovering and listing information about properties and determining property values. It also involves analyzing the values to ensure they meet the standards of fair assessment and certifying the assessment roll to the appropriate taxing authorities.

To ensure equalization, the assessor must determine residential property values by using only appropriate market information. Values for most other properties are determined from relevant cost, market and income data.
