A mill is $1 of tax for every $1,000 of assessed value. A home's assessed value is a fraction of its market value set by state law, so the tax on a home depends on its value and the assessment rate for its class.

Colorado requires every contract to buy and sell residential real property to include a statement that the property may be in special taxing districts that can carry general obligation debt (C.R.S. §38-35.7-101). Since August 2025, sellers of homes in metropolitan districts organized on or after January 1, 2000 must also give buyers an estimate of the property tax the districts impose (C.R.S. §38-35.7-110). We don't decide whether a disclosure is required for a given sale.
