On Aug. 4, Missouri voters will decide whether to renew a one-tenth of one percent sales tax that quietly props up the state park system and soil-and-water conservation programs. The modest levy has covered playgrounds, trail repairs and conservation grants across the state for more than 40 years. Supporters say keeping it in place would help keep state park admission free and head off maintenance shortfalls. If voters reject it, the dedicated tax would lapse in 2028, and officials warn that parks and farm conservation programs would lose a major, steady funding stream.
What's on the ballot
On May 22, Gov. Mike Kehoe signed proclamations placing Amendment 1, the Parks, Soils and Water Sales Tax renewal, on the Aug. 4 primary ballot. His announcement summarized the question as whether to “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.” The proclamations bundled Amendment 1 with three other constitutional amendments that will also appear in August, according to Governor Mike Kehoe.
Numbers behind the measure
The levy is tiny at the cash register but big in the state budget. It generates roughly $136 to $140 million a year and, on average, costs each Missourian about $10 annually. The revenue is split evenly between Missouri State Parks and the state’s soil-and-water conservation program, and by law the tax must go back to voters every 10 years. Backers point to its long record of voter approval, noting it has passed repeatedly since 1984, as a sign of broad support, according to reporting from KSMU / The Independent.
Where the money goes
Most of the parks share pays for day-to-day operations, visitor services and a steady list of upgrades. That includes new playgrounds, campground improvements, accessibility projects and trail renovations. Missouri State Parks says the dedicated funding accounts for roughly 75 percent of its budget and helps maintain more than 2,000 structures and 3,500 campsites. It also supports about 1,000 miles of trail while welcoming nearly 20 million visitors and more than 1 million overnight guests each year. Those inventories and visitor figures appear in materials about the parks sales tax renewal from the Missouri Department of Natural Resources.
Soil conservation impact
The soil-and-water half of the tax backs a statewide cost-share program run through local conservation district boards in all 114 counties. The money helps pay for terraces, cover crops, streambank stabilization and other erosion control projects on working land. Since the tax first passed in 1984, Missouri districts report putting more than 288,000 conservation practices on the ground and preventing roughly 193 million tons of soil from eroding. The association likes to translate that as more than 52 feet of dirt piled over the lanes of I-70 between St. Louis and Kansas City, which is a lot of topsoil by any standard. Those totals are documented in state and association reports, including materials from the Missouri Association of Soil and Water Conservation Districts.
Political context
The parks tax has typically drawn bipartisan support, but this summer backers are more nervous than usual. They warn that a crowded August ballot and louder anti-tax messaging around a separate income-tax overhaul could complicate the renewal effort. Political operatives and conservation supporters say the main risk is not the substance of the parks question, but voter confusion and turnout patterns when several high-profile amendments appear at the same time. Reporters following the rollout have flagged those campaign concerns as advocacy groups and opponents begin advertising, according to KSMU / The Independent.
How to vote
Election Day is Aug. 4, 2026. Absentee voting for voters with qualifying reasons opened in late June, and no-excuse absentee voting is scheduled to begin in late July. County election authorities and the Secretary of State publish the key deadlines and procedures, so anyone interested in voting by mail or early in person should check with their county office for the fine print. Local outlets have pulled together quick explainer guides to the August calendar and ballot questions, including a summary from WGEM.
The stakes are very local. Jefferson County and nearby parks such as Mastodon State Historic Site, Sandy Creek Covered Bridge and Don Robinson State Park rely on the dedicated sales tax for basic upkeep and visitor improvements.
