Proposes a constitutional amendment relating to taxation

HJR 174 proposes a constitutional amendment that would allow Missouri to eliminate its individual income tax by 2031 if specific revenue targets are met, while requiring the state to offset any revenue lost from this change. It prohibits expanding sales taxes to new services beyond those taxed in 2015 and mandates that local governments reduce other taxes (like property or sales taxes) if they expand the sales tax base to fund income tax elimination. The amendment also requires the state to adjust sales tax rates to maintain historical revenue levels after 2028 and exempts certain tax increases from revenue caps. This is a proposed amendment requiring voter approval, not current law, and does not affect existing tax debts or taxes on businesses, trusts, or estates.
