File Missouri Taxes & Get Your Tax Refund Faster

Anyone who is considered a resident, a partial-year resident, or a nonresident earning money in Missouri must file a state tax return. Nonresidents earning Missouri income must file, but they don't need to include income from other states unless they choose to file a combined return. If a taxpayer dies before he or she is able to file their taxes, that individual's surviving spouse may file for the decedent.

The top income tax rate is 4.8%, which makes Missouri relatively competitive compared to other states with income taxes. The state's tax revenue per individual is close to $1,000 annually. This is close to the median range for all of the United States.

Missouri Tax Rate Structure

Missouri uses a graduated income tax system with eight tax brackets for 2024:

$0 to $1,273: 0% - $1,274 to $2,546: 2%
$2,547 to $3,819: 2.5% - $3,820 to $5,092: 3%
$5,093 to $6,365: 3.5% - $6,366 to $7,638: 4%%
$7,639 to $8,911: 4.5% - $8,912 and over: 4.8%

These brackets are the same for all filing statuses, making Missouri unique among graduated income tax states.

Filing Requirements

You must file a Missouri return if:

You're a resident and file a federal return (with some exceptions for very low income)
You're a nonresident who earned $600 or more from Missouri sources.
Your Missouri adjusted gross income exceeds $1,200 (residents).

Some cities like St. Louis and Kansas City also impose a 1% local income tax on residents and those who work within city limits.
