Mo. Rev. Stat. § 147.010
1. For the transitional year defined in subsection 4 of this section and each taxable year beginning on or after January 1, 1980, but before January 1, 2000, every corporation organized pursuant to or subject to chapter 351 or pursuant to any other law of this state shall, in addition to all other fees and taxes now required or paid, pay an annual franchise tax to the state of Missouri equal to one-twentieth of one percent of the par value of its outstanding shares and surplus if its outstanding shares and surplus exceed two hundred thousand dollars, or if the outstanding shares of such corporation or any part thereof consist of shares without par value, then, in that event, for the purpose contained in this section, such shares shall be considered as having a value of five dollars per share unless the actual value of such shares exceeds five dollars per share, in which case the tax shall be levied and collected on the actual value and the surplus if the actual value and the surplus exceed two hundred thousand dollars. If such corporation employs a part of its outstanding shares in business in another state or country, then such corporation shall pay an annual franchise tax equal to one-twentieth of one percent of its outstanding shares and surplus employed in this state if its outstanding shares and surplus employed in this state exceed two hundred thousand dollars, and for the purposes of sections 147.010 to 147.120, such corporation shall be deemed to have employed in this state that proportion of its entire outstanding shares and surplus that its property and assets employed in this state bears to all its property and assets wherever located. A foreign corporation engaged in business in this state, whether pursuant to a certificate of authority issued pursuant to chapter 351 or not, shall be subject to this section. Any corporation whose outstanding shares and surplus as calculated in this subsection does not exceed two hundred thousand dollars shall state that fact on the annual report form prescribed by the secretary of state. For all taxable years beginning on or after January 1, 2000, but ending before December 31, 2009, the annual franchise tax shall be equal to one-thirtieth of one percent of the corporation's outstanding shares and surplus if the outstanding shares and surplus exceed one million dollars. Any corporation whose outstanding shares and surplus do not exceed one million dollars shall state that fact on the annual report form prescribed by the director of revenue. For taxable years beginning on or after January 1, 2010, but before December 31, 2011, the annual franchise tax shall be equal to one-thirtieth of one percent of the corporation's outstanding shares and surplus if the outstanding shares and surplus exceed ten million dollars. For all taxable years beginning on or after January 1, 2010, but before December 31, 2015, any corporation whose outstanding shares and surplus do not exceed ten million dollars shall state that fact on the annual report form prescribed by the director of revenue. For all taxable years beginning on or after January 1, 2011, but before December 31, 2015, a corporation's annual tax liability under this chapter shall not exceed the amount of annual franchise tax liability of such corporation for the taxable year ending on or before December 31, 2010. If the corporation had no annual franchise tax liability under this chapter for the taxable year ending on or before December 31, 2010, because such corporation was not in existence or doing business in Missouri, the annual franchise tax for the first taxable year in which such corporation exists shall be determined by applying the applicable rate of tax provided under the provisions of this subsection to the corporation's outstanding shares and surplus if the outstanding shares and surplus exceed ten million dollars, but in no case shall such corporation's tax liability for any subsequent taxable year exceed the amount of annual franchise tax liability of such corporation for the first full taxable year such corporation was in existence or doing business in Missouri. For taxable years beginning on or after January 1, 2012, the annual franchise tax shall be equal to the percentage rate prescribed in this subsection for the corresponding taxable year of the corporation's outstanding shares and surplus if the outstanding shares and surplus exceed the corresponding minimum threshold amount prescribed as follows:
