Proposes a constitutional amendment to impose an appropriation spending limitation, implement sales and use tax changes, and establish the "Tax Reform Fund" to be used to fund budgetary shortfalls, subject to an appropriation limitation, and allow for certain taxation changes based on revenue triggers, by general law

HJR 76 proposes a constitutional amendment that would impose population-based spending limits on Missouri's state budget, require a "Tax Reform Fund" to collect surplus revenue, and trigger automatic personal income tax reductions when the fund reaches specific balances. It limits annual state spending to 100% of the previous year's spending plus population growth (or 101% if population growth is under 1%), while creating a fund that collects excess revenue starting July 2027. The fund would automatically trigger personal income tax cuts of 0.1% for every $60 million over $120 million in the fund, with taxes reduced to zero once fully phased out, followed by corporate tax elimination. The amendment also freezes state sales taxes on services not taxed as of January 2015 and restricts using the fund for anything other than budget shortfalls after tax reductions.
