Missouri voters will decide on a constitutional amendment allowing state lawmakers to expand sales taxes and eventually eliminate the state's income tax. Supporters argue this would boost economic growth and attract businesses and residents, increase workers’ take-home pay, modernize the tax system, and limit state spending. Critics argue this could shift costs onto working families and seniors. The Republican-led House voted 95-59 to approve the proposed constitutional amendment. If approved, it would remove a constitutional restriction that restricts the state’s ability to extend sales taxes to services and transactions not taxed as of Jan. 1, 2015. Future legislatures will decide which goods and services to tax, with income tax reductions expected to occur over time as revenue grows. The nonpartisan Missouri Budget Project called the proposal "regressive" and warned that shifting from income taxes to sales taxes would increase costs for lower- and middle-income residents while reducing state revenue.
