Property Valuations for Individuals and Businesses

Why Is Property Reappraised?

The Montana Constitution and state law require periodic reappraisal of property in the interest of equal taxation (15-7-111, MCA).  The State of Montana, through the Department of Revenue (DOR), is responsible for valuing all taxable real and personal property. Once every six years, the DOR is required by state law to conduct a reappraisal of residential, commercial, industrial, agricultural and forestland property in the state.  We follow state guidelines to ensure property is appraised in a fair and equitable manner.

Since 1972, the Department of Revenue has completed six statewide reappraisals. The most recent reappraisal cycle began on January 1, 2003 and was completed on July 1, 2008.  New reappraisal values will be used for property tax purposes in tax year 2009.  By law, the reappraisal values will be phased-in at the rate of one-sixth each year.
