Colorado law 39-1-104 (10.2) (a) C.R.S. requires a two-year reassessment cycle for all taxable real property. The Assessor mails a Notice of Value (NOV) by May 1st of every odd numbered year. The Notice of Value will describe the property you own and give the value used for the next year’s taxes. You have the right to appeal your value each year regardless of value changes. The Assessor’s Office hears appeals on real property valuations in May of each year. In an intervening year (even numbered year) only those properties with a change of 75% in actual value will receive a Notice of Value.
