The Yuma County Assessor sets value, not the tax payment
A Porch Note from Colorado Porch — plain-English local details for all 64 Colorado counties.
One property tax bill in Yuma County passes through two different offices, and knowing which does what saves a lot of misdirected phone calls. The Assessor discovers, lists, and values property. Once that work is done and the tax roll is turned over, the Treasurer takes over and collects what is owed.
So the office you call depends on the question. Anything about the property record itself goes to the Assessor: whether the class, the owner, the description, or the value looks right. Anything about money goes to the Treasurer: a payment, a deadline, a delinquency, or whether a balance is still due. Calling the wrong one rarely gets you a wrong answer, just a slower one.
The same split is worth holding in mind before you make an offer on a place. The current bill is simply the assessed value multiplied by the mill levies for that taxing area, and it describes the property as it stands today. It is not a guarantee that next year lands in the same spot. A change in ownership, in how the land is used, or in the valuation can move the number, sometimes by a fair amount. Read today’s bill as a snapshot, not a fixed price, and you will not be caught off guard when the next one arrives.
