The Department of Revenue intends to expedite its 2009 energy rule review.  This may result in adoption of different Montana credit standards that are simpler and conform more closely with the federal credit standards.  Taxpayers may rely on existing administrative rules until changes are made.  Please check this site for updates.  If you would like to receive rule-making notices, please contact Cleo Anderson, Department of Revenue, Director's Office, P.O. Box 7701, Helena, Montana 59604-7701; telephone (406) 444-5828; fax (406) 444-3696; or email canderson@mt.gov.
