Kehoe Signs Proclamations Placing Four Amendments on August Ballot

Jefferson City, Mo. (KFMO) - Missouri voters will see four proposed constitutional amendments on the August 4, 2026 primary election ballot following action Friday by Governor Mike Kehoe.

Governor Kehoe announced he signed proclamations placing Amendment 1, Amendment 2, Amendment 4, and Amendment 5 before voters statewide.

In a statement, Kehoe said several significant issues are expected to come before Missouri voters this year and emphasized the importance of allowing time for public consideration and legislative preparation.

"Modernizing Missouri's outdated tax code, specifically, will be a momentous task for the Missouri General Assembly, and placing the measure to phase out Missouri's income tax on the August ballot gives lawmakers additional time to prepare for the next phase of implementation," he said.

According to the Governor’s Office, Amendment 1 would continue for another 10 years the one-tenth of one percent sales and use tax dedicated to soil and water conservation efforts along with Missouri state parks and historic sites.

Amendment 2 would require all charter counties, including Jackson County, to elect a county assessor and require assessors to comply with state-established training requirements.

Amendment 4 would change Missouri’s initiative petition process by requiring not only a statewide majority vote for constitutional amendments, but also approval from a majority of voters in each congressional district. The proposal would also make the full text of initiative petitions available to voters with their ballots.

Amendment 5 proposes phasing out Missouri’s individual income tax based on revenue growth. The amendment would also require reductions in property taxes and other local taxes to offset increases in local sales tax revenue while maintaining funding for public schools.

Kehoe said lawmakers want to ensure the state is prepared to responsibly implement any voter-approved changes.

All additional certified ballot measures will appear on the November 2026 General Election ballot.
