Montana Title 15. Taxation § 15-31-143. Return and payment on corporate dissolution

(1) Each corporation doing business in Montana shall pay an excise tax for the exercise of that privilege, and the amount of the excise tax must be based upon the total taxable net income of a corporation during the entire period of time that it is engaged in business in this state. No remission of that obligation for the last year in which a corporation engages in business in Montana was intended by the original enactment of this section.

(2) Each corporation that is dissolved or ceases to do business in Montana shall, upon the dissolution or cessation of business, make a return and pay the corporate income tax determined on the basis of its net income for the final period in which it did business in this state at the rate provided in 15-31-121 and 15-31-122, in addition to all other corporate income taxes for which the corporation may then be liable.
