Current Actual Value x Assessment Rate* = Assessed Value

Assessed Value x Tax Rate (Mill Levy) = Estimated Property Tax

*Current Assessment Rate (2006 and 2007) is projected to be 7.96% for residential property and 29% for all other property. The Colorado State Legislature adjusts the residential assessment rate in reappraisal (odd- numbered) years.

ACTUAL VALUE X ASSESSMENT RATE X MILL LEVY = ESTIMATED PROPERTY TAXES.

Tax rates (mill levies) are determined by each taxing authority (County, City, School District, Fire Department, Water & Sanitation District & Recreation District) in the fall of each year. These authorities provide services to you and are listed on your last tax notice.  Amendment 1, known as the Tabor Amendment approved by the voters in 1992, restricts the ability of taxing authorities to raise tax rates or revenue without voter approval. Some tax authorities have chosen to provide temporary tax credits, which allows the tax district to maintain its official mill levy and not exceed revenue limits.

The title on property can be changed via a recorded deed. The Assessor’s Office is an "office of record," which means changes in ownership or property boundaries are done based on recorded deeds, surveys, subdivision plats & other documents pertaining to ownership.  Deeds must be recorded at the Clerk & Recorder’s Office before the Assessor’s records can be modified to reflect any changes.

It isn’t necessary to mail or bring us a copy of the recorded deed. The Assessor’s Office accesses all recorded documents from the Clerk & Recorder’s Office that concern ownership changes.

It is the responsibility of the property owner to notify the Assessor’s Office of any change in mailing address. To protect the taxpayer from an erroneous address change, the address used by the Assessor’s Office will not be changed without the property owner’s written consent.  For your convenience, you may download an address change form from this site, complete & mail. Every year, many people don’t receive the notices we send because they have not kept us advised of their changed addresses.
