Missouri Governor Puts 4 Constitutional Amendments on Aug. 4 Ballot

Governor Mike Kehoe signed proclamations placing Amendments 1, 2, 4 and 5 on Missouri’s Aug. 4, 2026, primary ballot, while any other certified measures will wait for the November general election.
Amendment 5 is the highest-profile proposal: it would phase out Missouri’s individual income tax based on revenue growth and require cuts to property and other local taxes while preserving school funding.
The August ballot also includes a 10-year extension of the 0.1% sales and use tax for soil, water, parks and historic sites; a requirement that charter counties elect assessors; and stricter approval rules for constitutional initiatives.
Kehoe said moving the measures to August gives voters more time to weigh them and gives lawmakers added time to prepare, especially for the tax-code changes that would follow an income-tax phaseout.
