Can you estimate my taxes based on the value of my property?

The formula for computing taxes is as follows:

Actual Value X Assessment Ratio = Assessed Value. Assessed Value X Mill Levy = Taxes


The Assessor’s responsibility is to determine the actual value and classification of real and personal property. Generally, the Assessment Ratio for real and personal property in Colorado is 29%, except for improved residential property. The residential assessment ratio must be adjusted every two years by the State Legislature to conform with the 1982 “Gallagher” Amendment to the Colorado Constitution. Under the Gallagher Amendment, that ratio is subject to review and possible change by the State Legislature to comply with the formula contained within the Amendment at every two-year re-appraisal cycle. For tax years 2015 and 2016, this ratio was 7.96%, 7.20% for tax years 2017 and 2018, and is currently 7.15%.  The various mill levies are set each December by the various taxing entities. The 1992 “TABOR” Amendment to the Colorado Constitution generally requires a vote to be taken in the appropriate taxing district in order to raise a mill levy. Provisions of the TABOR Amendment regulate the increase in the revenue a taxing entity may be allowed, which can result in lowering of levies under some circumstances. The Assessor has no control of either the setting of the assessment ratio or mill levies.
