Mo. Rev. Stat. § 351.125

Every corporation required to register under the provisions of this chapter shall pay to the state a fee of forty dollars for its corporate registration if the report is filed in a written format. The fee is fifteen dollars for each corporate registration report filed via an electronic format prescribed by the secretary of state. Biennial corporate registration reports filed under section 351.122 shall require the fee prescribed in that section. If a corporation fails to file a corporation registration report when due, it shall be assessed, in addition to its regular registration fee, a late fee of fifteen dollars for each thirty-day period within which the registration report is filed whether in writing or in an electronic format. If the registration report is not filed within ninety days, the secretary of state may proceed with administrative dissolution of such corporation under sections 351.484 and 351.486.
