Montana taxes homes on a fraction of market value: taxable value = market value × residential rate. A mill is one dollar of tax per $1,000 of taxable value: annual cost = taxable value ÷ 1000 × mills. A dollar-amount levy converts to mills by dividing by the district's total taxable value: mills = levy ÷ district taxable value × 1000.
