Missouri Voter Information
The link between voting and health outcomes is complex: individuals from marginalized backgrounds often experience poorer health, and limited access to voting is associated with worse health outcomes. This results in decreased representation of marginalized groups and those with chronic illnesses. Consequently, a cycle emerges where poor health leads to reduced voting, diminished political influence, and policies that overlook the needs of marginalized communities.
We are here, along with our partners, to help you make a plan to vote in upcoming elections. Share the information below with your communities and networks to help us get out the vote!

Issues on the Ballot
There are 4 constitutional amendments on the Missouri primary election ballot this August. These are issues that every Missourian will see on their ballot when they go to vote. However, you will likely see additional local issues on your local ballot. Be sure to do your own research on each issue to make an informed decision.
Amendment 1 – Renewal of the One-Tenth-of-a-Cent Sales Tax for State Parks and Conservation
Missouri Constitutional Amendment 1 would renew the existing one-tenth-of-a-cent state sales tax for an additional 10 years. This tax was first passed in 1984 and was last renewed in 2016, and the continuation of the sales tax is resubmitted to the Missouri ballot every 10 years for voter approval. The existing sales tax raises approximately $140 million a year to fund state parks, historic sites, soil and conservation programs, and agricultural land projects, and the funds cannot be used for any other state purpose.
A “yes” vote will continue for 10 years the one-tenth of one percent sales/use tax that is used for soil and water conservation and for state parks and historic sites.
A “no” vote will not continue this sales/use tax.
If passed, this amendment will not increase or decrease taxes.

Amendment 2 – County Assessor Election for Jackson County
Missouri Constitutional Amendment 2 proposes that Jackson County require that the county assessor, who determines property valuations, be elected by Jackson county residents’ vote rather than appointed by the county. Currently, all other counties in Missouri are required to hold elections for their respective county assessors. This measure would make county assessor elections a standard practice for all charter counties statewide. It would also require all county assessors to complete any training requirements set by law.
A “yes” vote will require that all charter counties, including Jackson County, elect a county assessor and that such assessors comply with training requirements established by state law.
A “no” vote will not change the current constitutional provisions, which exempt Jackson County from the requirement to elect its assessor and do not require charter county assessors to follow training requirements under general law.

Amendment 4 – Separate Majority Approval in Each Congressional District for Constitutional Amendments
Missouri Constitutional Amendment 4 would require a simple majority of votes statewide AND separate majorities of votes in each of Missouri’s 8 congressional districts in order for state constitutional amendments proposed by initiative petition drives to be passed. If only 7 out of 8 congressional districts have a majority vote, a constitutional amendment will not pass. Currently, citizen-initiated constitutional amendments only require a statewide simple majority, similar to constitutional changes proposed by the state Legislature. Additionally, this amendment would codify the existing state prohibition of political contributions from international governments and political entities in the state constitution, as well as current state laws against petition signature fraud. This amendment would also require the full text of initiative petition proposals to be provided to voters on their ballots, not just at polling places. The Department of Corrections estimates increased annual costs of up to $21,817.
A “yes” will require voter approval of citizen-initiated constitutional amendments in each congressional district, rather than statewide, require the full text of citizen-initiated constitutional amendments on voters’ ballots.
A “no” vote will not require majority approval in each congressional district for initiative petitions to amend the constitution or make available the full text of initiative petitions with the ballot.

Amendment 5 – State Income Tax Elimination and Sales Tax Changes
Missouri Constitutional Amendment 5 proposes the phasing out of the state income tax and allowing the Legislature to expand state and local sales and use taxes over the next 5 years to include currently exempt goods and services. The state would swap the generation of $9 billion in revenue from the income tax to the expanded sales tax. This amendment would not require voter approval for sales tax increases during the expansion period, and the sales tax could be applied to any and all products and services, as the amendment does not include any exemptions. State government entities expect a reduction of $57,000 annually in income tax check-off donations and implementation costs of at least $100,000.
A “yes” vote supports the elimination of the individual state income tax and the expansion of sales and use taxes without constitutional limits on which goods and services can be taxed and how much.
A “no” vote will not eliminate the individual state income tax and will not authorize the expansion of sales and use taxes, maintaining current constitutional limits.
