The director shall prescribe and publish all needed rules and regulations necessary for the enforcement of sections 148.610 to 148.700. Insofar as feasible, as may be determined by the director, such rules and regulations shall be consistent with the rules and regulations prescribed by the United States Commissioner of Internal Revenue for the enforcement of the income tax chapter of the Internal Revenue Code. The directors of division of finance and of credit union supervision shall make available to the director upon the director’s request any report filed by any taxpayer subject to the tax imposed by sections 148.610 to 148.700, and such director shall be under the same obligation as to secrecy with respect thereto as is imposed upon the directors of division of finance and of credit union supervision, by law. No rule or portion of a rule promulgated under the authority of this chapter shall become effective unless it has been promulgated pursuant to the provisions of section 536.024.
