What are Missouri's 2024 income tax brackets?

Missouri uses graduated brackets that rise in small steps from 0% on the first slice of income up to a top marginal rate of 4.8% for 2024. The brackets are narrow, so most filers with moderate income reach the top rate. The standard deduction shelters income before any rate applies.

What is the Missouri standard deduction?

Missouri adopts the federal standard deduction: about $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household in 2024. You subtract this (or your itemized deductions) from income before applying the brackets.

Is Missouri income tax based on federal AGI?

Yes. Missouri starts from your federal adjusted gross income, then applies Missouri additions, subtractions, and the standard or itemized deduction to reach Missouri taxable income. This tool uses AGI minus your deduction as a simplified taxable base.

Does Missouri allow a deduction for federal taxes paid?

Missouri historically allowed a limited deduction for a portion of federal income tax paid, subject to income-based phaseouts. That subtraction is not modeled in this simplified tool, so your actual Missouri taxable income could be slightly lower than shown.

Why is this an estimate?

Your real Missouri tax depends on credits, special subtractions (such as pension or military income), additions, and the exact current bracket thresholds. This calculator applies the standard deduction and graduated brackets to give a close estimate, not an official return figure.

The Missouri Income Tax Calculator estimates your state income tax for 2024. Missouri uses graduated brackets that climb in small steps from 0% to a top marginal rate of 4.8%. You subtract the standard deduction (matching the federal amount) or your itemized deductions before the brackets apply.

How it works

Missouri starts from your federal AGI and applies a deduction:

taxable income = AGI - standard (or itemized) deduction
state tax      = graduated brackets on taxable income
effective rate = state tax / AGI

The brackets are narrow — each band is roughly $1,273 wide for 2024 — so taxable income above about $8,900 is taxed at the top 4.8% rate. Only the income inside each band is taxed at that band’s rate, which is what keeps the effective rate below the marginal rate.

How the brackets stack

0%     on the first slice of taxable income
2.0%   next band
2.5%, 3.0%, 3.5%, 4.0%, 4.5%   stepping up
4.8%   on all taxable income above the top threshold

Example and notes

A single filer with $65,000 of income taking the standard deduction:

deduction: $14,600
taxable: $50,400
state tax: roughly $2,260
effective rate: ~3.5%
