If the cemetary is certified by the county as a valid burial ground, it is considered to be exmept. However if the cemetary was never certified, it does remain potentially taxable under state and county levies. Here are the codes that govern:
MONT CODE ANN § 35-20-217 : Montana Code - Section 35-20-217: EXEMPTION FROM TAXATION AND EXECUTION -- NO ROAD CONSTRUCTION THROUGH CEMETERY
The cemetery lands and property of any association formed pursuant to this chapter are exempt from all public taxes and assessments and not liable to be sold on execution or applied in payment of debts of any individual proprietors; but the proprietors of lots in such cemetery, their heirs or legal representatives may hold the same exempt therefrom so long as the same remain appropriated to the use of a cemetery, and during that time no street or road shall be laid through such cemetery or any part of the lands held by such association for the purpose aforesaid without the consent of the trustees of such association.
