Missouri Primary Election - August 4, 2026

Four Important Amendments

Missouri’s August 4, 2026 primary is a high-stakes election, with four major constitutional amendments on the ballot that could shape the state’s laws and priorities for decades. With decisions this far-reaching, every eligible voter’s voice matters.

Turning out on August 4 isn’t just about choosing policies for today — it’s about protecting Missouri’s future and ensuring the outcomes reflect the will of the people.

  • Missouri’s long-standing 1/10 of 1% tax—just 1¢ on a $10 purchase—doesn’t increase taxes and has been renewed for decades. It provides 75% of State Park funding and supports soil and water conservation. Ending it would severely damage our top-ranked parks and vital conservation work.

    YES on 1 would: extend the tax for 10 years, maintaining free access to state parks, upkeep of trails and facilities, conservation work on agricultural land, and a stable dedicated funding stream outside the annual budget process.

    NO on 1 would: end the tax when it expires in 2028, eliminating a major funding source for parks and conservation programs.

    BOTTOM LINE: This funding stream is essential to protecting what Missourians have built together—our parks, historic sites, clean water, and working land. This is a proven, voter-controlled mechanism that costs pennies and delivers results.

  • Currently, most Missouri counties elect their assessor, but charter counties — including Jackson County — can choose to appoint one instead. This amendment would change that.

    YES on 2 would:

    • Require all charter counties to elect their assessor rather than appoint one.

    • Require assessors in those counties to meet training standards set by state law.

    NO on 2 would: leave things as they are — Jackson County and other charter counties could continue appointing their assessor, and no training requirements would be added.

    BOTTOM LINE: Amendment 2 decides whether charter counties must elect their assessor or keep the option to appoint one.

  • YES on 4 would:

    • Require a statewide majority PLUS a majority in EVERY congressional district to pass a citizen-initiated constitutional amendment. One district representing as few as 6% of voters could block what 94% of Missourians support.

    • Create a double standard: legislators' amendments still need ONLY a simple statewide majority.

    • Have killed Medicaid expansion, minimum wage increases, marijuana legalization, and reproductive rights protections.

    NO on 4 would:

    • Keep the current process: a simple statewide majority for everyone — citizens and legislators alike.

    BOTTOM LINE: Amendment 4 rigs the rules against voters. YES silences voters. NO keeps Missourians in charge.

  • YES on 5 would:

    • Phase out the state income tax, cutting funding for K-12 schools, infrastructure, and essential services.

    • Authorize new sales taxes on goods and services not currently taxed — including real estate, health care, and gasoline — with no cap on how high legislators can raise them.

    • Raise taxes on 60–80% of Missourians. Only those earning near $300,000 or more would see a cut.

    NO on 5 would:

    Keep the current tax system and protect funding for schools, roads, and essential services without shifting the burden onto everyday Missourians.

    BOTTOM LINE: YES cuts taxes for the wealthy and raises them for everyone else — then hands politicians a blank check to keep raising sales taxes with no limit. NO keeps the system fair.
