What is reappraisal?
Montana law requires the Department of Revenue to reappraise or revalue all taxable real property—that is, buildings or land that are residential, commercial, industrial, agricultural, or forest-related—every six years (or once for every six-year cycle). The last six-year cycle ended on December 31, 2008. Tax year 2009 is the first year of the current six-year cycle (the 2009 reappraisal cycle).
