New Missouri law cuts state income tax, with further reductions possible
October 17, 2022 at 12:00 PM

Missouri Gov. Mike Parson recently signed into law legislation that reduces the state's individual income tax rate.

The law, signed on Oct. 5, 2022, and effective for the 2023 calendar year, reduces the top individual income tax rate from 5.2 percent to 4.95 percent. It also eliminates the bottom income tax bracket, allowing Missourians to earn their first $1,000 tax-free. In addition, the law allows for an additional 0.15 percent top income tax rate reduction to 4.8 percent when Missouri’s net general revenues increase by $175 million and another 0.1 percent top income tax rate reduction in future years when net general revenue of the state increases by $200 million. If Missouri’s revenue increases as stated above and the corresponding rate reductions take effect, the new legislation will reduce the top income tax rate in Missouri to 4.5 percent.  

Finally, the new law eliminates the imposition of income tax on individuals making less than $13,000 a year and couples making less than $26,000 per year. It does not contain any state-level tax rate changes for corporations.

Previously, Missouri's top individual income tax rate was scheduled to fall from 5.3 percent to 5.2 percent in January, with the potential to gradually drop to 4.8 percent if revenue thresholds were exceeded in future years. The changes in Missouri’s income tax rates do not affect federal taxes. A summary of the current federal rates for 2022 is below:
