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.
