Missouri’s top individual income tax rate will decrease from 5.9% to 5.4% beginning in 2019. Gov. Mike Parson signed legislation containing the tax cut.
The top rate can drop further to 5.1% if the state meets revenue targets. The rate will decrease by 0.1% for each year that the state meets the targets.
Deduction for Federal Income Taxes
To offset the tax cut, Missouri limits the deduction for federal income tax paid. Single filers may still deduct up to $5,000, and combined filers may still deduct up to $10,000. But, beginning in 2019, Missouri phases out the deduction at specified Missouri adjusted gross income levels. The Missouri adjusted gross income levels and the deductible percentages of federal income tax are:
- $25,000 or less – 35%
- $25,001 to $50,000 – 25%
- $50,001 to $100,000 – 15%
- $100,001 to $125,000 – 5%
- $125,001 or more – 0%
Business Income Deduction
Missouri also reduces the maximum business income deduction for individuals from 25% to 20%.
Finally, Missouri will not allow personal and dependent exemptions when a taxpayer’s federal exemption amount is zero.
