A Dolores County tax bill is built from three moving parts

A property tax bill in Dolores County can feel like one number, but it is built from three parts, and knowing them takes the mystery out of it.

First, the county assessor sets the property’s actual value. Second, an assessment rate set by state law turns that value into a smaller taxable amount, called assessed value. The rate depends on the property’s classification, and under current law a home can even have one assessed value for school district taxes and a different one for other local governments. Third, the districts that cover your land, things like the county, a school district, a town, or a fire or special district, each add a mill levy. Each district’s levy is applied to the assessed value that applies to it, and the results add up to your tax.

This is why two homes with similar prices can owe different amounts. They may sit under a different mix of districts, each with its own levy. It also explains the two county offices you will deal with: the assessor, who handles value, and the treasurer, who sends the bill and collects payment.

Rates and levies change year to year, so this note describes the structure, not a number. For your own parcel’s value, the districts on it, and current rates, use the Colorado Division of Property Taxation and the Dolores County assessor and treasurer.
