Missourians decisively rejected a sales tax increase earmarked for transportation projects, making for a striking defeat for a well-financed campaign from proponents and a victory for an ideologically diverse opposition coalition. 

The tax – commonly known as “Amendment 7” or the “transportation tax” – would have raised Missouri’s sales tax by 0.75 percent for 10 years. It would have also barred Missouri's policymakers from instituting tolls or raising the state’s gas tax during that same time period.

Missourians will vote Aug. 5 on a 0.75 percent sales tax increase for transportation projects. The proposal — commonly known as the transportation tax — would generate billions of dollars over the next decade to fix roads, repair bridges and improve mass transit. 

The stakes are high. Supporters say Missouri needs more money for its aging transportation infrastructure. With gas tax revenue dwindling and federal funding uncertain, some policymakers see the sales tax as a guaranteed way to fund transportation needs.
