Modifies and creates new provisions related to the regulation and use of gold and silver

HB 1867 modifies Missouri tax laws to adjust how state funds are managed and how individual income taxes are calculated. The bill requires the state treasurer to keep a portion of state funds in gold or silver, known as specie, within local banks if the amount reaches one percent of total state funds. For taxpayers, the legislation changes how federal tax refunds, interest on government bonds, and certain deductions are treated when calculating Missouri income tax liability. These adjustments aim to align state tax calculations with specific federal rules while excluding certain pandemic-related financial assistance from state tax benefits.
