Income Taxes

The Missouri House also approved sex trafficking legislation on Thursday.

A resolution in the Missouri General Assembly, if approved, would create a process to eliminate the individual income tax as soon as 2032. It would allow for an expansion of some sales taxes to recoup funding lost as a result of lowering or eliminating this tax. Any resolution passed in the statehouse would have to be approved by voters.

A bad national environment for Republicans could affect this year's election cycle, which will feature critical ballot measures like a proposal to repeal abortion rights, restricting citizen-led initiative petitions, and deciding the fate of the gerrymandered congressional map.

About 60% of Missourians would experience a net tax increase under Gov. Mike Kehoe’s plan because of new sales taxes, while households in the top 1% would see an average tax cut of nearly $40,000.

Following a rocky end to last year’s legislative session, Democrats are looking to slow things down, while Republicans push to pass Gov. Mike Kehoe’s state income tax cuts. Political reporter Jason Hancock spoke with KCUR’s Up To Date about the slow start and early dysfunction in the Missouri General Assembly.

If passed by voters, a proposed constitutional amendment would allow Missouri's legislature to expand state and local sales and use taxes, while eliminating the state income tax. The AARP and Democratic lawmakers said that would shift more of the cost on seniors and low-income residents.

House Majority Leader Alex Riley will likely become Missouri’s speaker of the House after next year’s elections. But before then, he's responsible for shepherding Republican priorities like eliminating the state income tax.

Under the proposed constitutional amendment sponsored by House Speaker Jon Patterson, sales tax could be imposed “on transactions involving any goods and services." But Patterson said that will be amended to prevent more taxes on fill-ups.

In his 2026 State of the State address, Gov. Mike Kehoe said he wants a statewide vote in November on his plan to phase out the state income tax and allow for taxes on things like monthly subscriptions and digital services. Democrats have questioned whether that's possible without wrecking future budgets.

Missouri Senate Democrats say they're still irate over how the GOP cut off debate last year — pushing through legislation to redraw congressional maps, ban abortion and repeal paid sick leave.

Missouri lawmakers arrive in Jefferson City on Wednesday for the start of the 2026 legislative session, which runs until mid-May. Gov. Mike Kehoe is pushing to eliminate the state income tax, but a smaller budget will likely force spending cuts.

Missouri Republicans made big moves last legislative session to force through their agenda on abortion, redistricting and more — and now the consequences will be felt this year. Democrats are determined to stall action in the state Senate as retribution.
