The Parks, Soils and Water Sales Tax is a statewide one-tenth-of-one percent sales tax. It provides dedicated funding for Missouri state parks and historic sites along with soil and water conservation efforts. Missouri citizens have shown strong support for soil and water conservation and state parks by first approving it in 1984, as a constitutional amendment.

The tax was reapproved by two-thirds of Missouri voters in 1988, 1996, 2006 and 2016. In 2016, the tax was approved by approximately 80%, passing in every county. The tax now appears on the ballot every 10 years to reaffirm the voters’ support of the park system and soil and water conservation efforts.

The Parks, Soils and Water Sales Tax is set to expire in 2028, if not approved by voters in 2026.
