Missouri lawmakers moved one step closer to a historic overhaul of the state tax system after the Senate approved a plan that could eventually eliminate Missouri's state income tax. The measure faced bipartisan resistance, including opposition from three Republican senators. If finalized, Missouri voters could decide the issue at the ballot box.

Why it matters

Taxes affect household budgets, business investment, and state services. If Missouri removes the income tax, workers could see more take-home pay, but a heavier reliance on sales taxes could place a greater burden on working families. The final impact would depend on how the transition is designed and managed over time.

The details

Under the new plan, lawmakers would create a path to reduce and potentially eliminate the state's personal income tax over time. To offset lost revenue, the state could rely more heavily on sales taxes, use taxes, consumption-based revenue, or future economic growth. Supporters argue that income taxes discourage productivity and that lower taxes can attract employers, entrepreneurs, and new residents. Critics warn that eliminating income tax revenue could create budget instability unless replacement revenue is strong and consistent.

  • The Senate vote took place in April 2026.
