Establishes "The Constitutional Money Act" which regulates the treatment and use of gold and silver

HB 630 (the "Constitutional Money Act" title is misleading) primarily revises Missouri's income tax calculation rules, not gold/silver regulation. It modifies Section 143.121 to add specific federal tax items to Missouri adjusted gross income, including most federal tax refunds (except pandemic-related credits) and certain tax-exempt interest. The bill also adjusts business deduction rules for property purchased in 2002-2003 and changes how net operating losses are treated for state tax purposes. This directly affects Missouri residents and businesses filing state income tax returns by altering taxable income calculations. The brief reference to "specie" (gold/silver) in Section 30.266 relates only to the state treasurer holding a minimal 1% of state funds in physical currency, not regulating public use of precious metals.
