Certified Taxable Values

In late August, all 1,448 local government taxing jurisdictions will be receiving their individual certification of taxable values.  This delivery date is later than in past years due to our efforts to produce the most accurate values possible­­­–including the implementation of a change in the method we are required to use to calculate newly taxable values.  In the new calculation, the taxable value of new property is added to the tax rolls at full phase-in value (please see HB 658, approved by the 2009 Montana Legislature, for details).

Under Montana law a taxing jurisdiction still has 45 days from the receipt of the certification of taxable values to set its mill levy.
