Montana Title 15. Taxation § 15-1-206. Waiver of penalties--interest

(1) The department may, in its discretion, waive, for reasonable cause, any penalty assessed by the department.

(2) Whenever the department waives a penalty provided for in this title, it also may, in its discretion, waive interest not to exceed $500 due for each tax period. When the department enters into a payment plan with a taxpayer that allows the taxpayer to make installment payments of delinquent taxes, interest, and penalties, the department may, at the conclusion of the payment plan term, agree to waive an additional $100 of interest for each tax period if the taxpayer has complied with all of the provisions of the payment plan.
