19-20-106. Retaining qualified plan status -- board rulemaking authority. (1) The board shall administer the plan in the manner required to satisfy the applicable qualification requirements for a qualified governmental plan, as specified in the Internal Revenue Code. If a provision in this chapter conflicts with a qualification requirement in section 401 of the Internal Revenue Code applicable to public retirement systems or with the plan's status as a qualified governmental plan under section 414(d) of the Internal Revenue Code and consequent federal administrative regulations, the provision is either ineffective or must be interpreted to conform to the federal qualification requirements and allow the plan to retain tax-deferred status. The board may adopt rules to implement this section.

(2) For the purpose of section 401(a) of the Internal Revenue Code, the plan document for the retirement plan is composed of the applicable provisions of the Montana constitution, this chapter, and applicable rules adopted by the board.
