What would Amendments 4 and 5 mean for Missouri families and communities?
Both proposed constitutional amendments will appear on Missouri’s August 4 primary ballot, but they address different issues.
Amendment 4 is about Missouri’s citizen initiative-petition process—the process people use to place proposed constitutional amendments on the ballot.
Right now, a citizen-led constitutional amendment passes when it receives a majority of votes statewide. If Amendment 4 passes, it would need both a statewide majority and a majority in every Missouri congressional district. The full text of initiative petitions would also be made available to voters with their ballots. If it does not pass, the current statewide-majority rule would remain.
Amendment 5 is about Missouri’s income, sales and use tax structure.
If it passes, it would require lawmakers to phase out and eventually eliminate the individual state income tax when certain revenue-growth requirements are met. It would also authorize the expansion of sales and use taxes, reduce some existing constitutional limits on taxing goods and services, and require certain local tax-rate reductions if local sales-tax revenue increases. The official ballot information says the overall effect on taxes is currently unknown. If it does not pass, these constitutional changes would not take effect.
These questions may affect how Missourians make decisions through the initiative process, how the state raises revenue, and how public services—including healthcare, education and family supports—are funded.
