Mo. Rev. Stat. § 135.815
Prior to authorization of any tax credit application, an administering agency shall verify through the department of revenue that the tax credit applicant does not owe any delinquent income, sales, or use taxes, or interest or penalties on such taxes, and through the department of insurance that the applicant does not owe any delinquent insurance taxes. Such delinquency shall not affect the authorization of the application for such tax credits, except that the amount of credits issued shall be reduced by the applicant's tax delinquency. If the department of revenue or the department of insurance concludes that a taxpayer is delinquent after June fifteenth but before July first of any year, and the application of tax credits to such delinquency causes a tax deficiency on behalf of the taxpayer to arise, then the taxpayer shall be granted thirty days to satisfy the deficiency in which interest, penalties, and additions to tax shall be tolled. After applying all available credits towards a tax delinquency, the administering agency shall notify the appropriate department, and that department shall update the amount of outstanding delinquent tax owed by the applicant. If any credits remain after satisfying all insurance, income, sales, and use tax delinquencies, the remaining credits shall be issued to the applicant, subject to the restrictions of other provisions of law.
