How to Use This Calculator
Enter your income, filing status, and any deductions. The calculator computes your Missouri state income tax alongside your federal tax, showing exactly how much goes to each and what you take home.
The most useful thing to try? Compare different income levels to see how Missouri's brackets affect your tax bill, then look at how combined federal + state taxes shape your total take-home pay.
Here's what each field means:
Annual Income is your total earnings before any taxes. Include wages, freelance income, investment income, and any other sources.
Filing Status determines which set of tax brackets and deductions apply. Missouri uses filing statuses similar to the federal system — single, married filing jointly, married filing separately, and head of household.
Missouri Income Tax: What You Need to Know
Missouri uses a progressive income tax system with rates ranging from 2% to 4.7%. Like the federal system, this means your income is taxed in layers — each bracket only applies to the income within that range, not your entire income.
Missouri Tax Brackets (Single Filers)
| Taxable Income | Tax Rate |
|---|---|
| $0 - $1,273 | 0% |
| $1,273 - $2,546 | 2.0% |
| $2,546 - $3,819 | 2.5% |
| $3,819 - $5,092 | 3.0% |
| $5,092 - $6,365 | 3.5% |
| $6,365 - $7,638 | 4.0% |
| $7,638 - $8,911 | 4.5% |
| $8,911+ | 4.7% |
A Real Example
Let's say you're a single filer earning $60,000 in Missouri. After applying the standard deduction of $14,600, your income flows through each bracket:
Your approximate Missouri state income tax would be around $2,261, for an effective state tax rate of about 3.8%.
Remember, this is just the state portion. You'll also owe federal income tax and FICA taxes on top of this.
Deductions and Exemptions
Standard Deduction: Missouri offers a standard deduction of $14,600 for single filers and $29,200 for married couples filing jointly.
Federal standard deduction conformity, federal tax deduction (capped), personal exemption of $2,100, and Social Security exemption for lower-income residents.
Local Taxes
Kansas City and St. Louis levy local earnings taxes of 1% each. These apply to anyone who works or lives in those cities.
What's Unique About Missouri
Missouri has many brackets but the effective impact is modest — you hit the top 4.7% rate at just $8,911 of taxable income. Missouri conforms to the federal standard deduction, which simplifies filing. The top rate has been declining: it was 5.3% in 2023 and is scheduled to continue dropping. Missouri does not tax Social Security benefits for most residents (exempt if federal AGI is below $85,000 single / $100,000 MFJ). The state also allows a deduction for federal taxes paid, capped at $5,000 single / $10,000 MFJ.
Recent Changes
The top rate dropped to 4.7% in 2025 and is scheduled to continue declining if revenue triggers are met, potentially reaching 4.5%.
