Montana Title 69. Public Utilities and Carriers § 69-1-228. Credit for overpayment--interest on overpayment

(1) If the department of revenue determines that the amount of fee, penalty, or interest paid for any year is more than the amount due, the amount of the overpayment must be credited against any tax, penalty, or interest then due from the taxpayer and the balance refunded to the taxpayer or the taxpayer's successor through reorganization, merger, or consolidation or to the taxpayer's shareholders upon dissolution.

(2) Except as provided in subsection (3), interest is allowed on overpayments at the same rate as is charged on deficiency assessments from the due date of the return or from the date of overpayment, whichever date is later, to the date the department of revenue approves refunding or crediting of the overpayment.
