Missouri State Income Tax Overview
Missouri uses a graduated income tax system with rates starting at 2% and reaching a top rate of 4.8% for 2024 on income above $9,000, following a series of phased tax reductions. Missouri allows a deduction for federal income taxes paid, up to $5,000 for single filers and $10,000 for married couples, which can meaningfully reduce state taxable income. The state provides a standard deduction equal to the federal standard deduction. Missouri fully exempts Social Security benefits and 100% of public pension income for qualifying retirees. Military retirement pay is also fully exempt from Missouri state income tax.

Most full-year Missouri residents with income above the state filing threshold must file a state return. Check the Missouri Department of Revenue for current thresholds and requirements.
How accurate is this Missouri state tax estimate?
This is a planning estimate. The state result uses Missouri's published brackets but does not account for all state deductions, credits, exemptions, or local taxes. Verify with official Missouri tax forms or a qualified tax professional.
Does this calculator include federal income tax?
Yes. The results show your estimated Missouri state income tax and your federal income tax using 2025 federal brackets — your full combined picture in one place.
Where can I find official Missouri tax forms?

Understanding Your Missouri Tax Estimate
Your results show both your estimated federal income tax and your estimated Missouri state income tax as a combined picture. Here is how to read them and what to do next.
Federal vs. State Tax: Two Separate Bills
Federal income tax is owed to the IRS and is the same rate schedule for all U.S. residents regardless of where you live. Missouri state income tax is a separate obligation paid to the Missouri Department of Revenue. You file two separate returns — one federal (Form 1040) and one state — though they are often prepared together using tax software.
How the Estimate Is Calculated
This calculator applies the 2025 federal tax brackets to your taxable income (gross income minus the standard or itemized deduction), then applies Missouri's published state brackets to estimate your state liability. The result is a planning estimate — not a filed return. It does not account for all credits, deductions, or individual circumstances that could change your actual bill.
Marginal Rate vs. Effective Rate
Your marginal rate is the rate on your last dollar of income — it is the highest bracket you reach, not what you pay on all income. Your effective rate is your total tax divided by gross income, and is almost always meaningfully lower. For example, a single filer earning $75,000 may be in the 22% federal bracket but pay an effective federal rate of only 14-15%. The same principle applies to Missouri state brackets.
3 Ways to Reduce Your Missouri Tax Bill
- Maximize pre-tax retirement contributions. Traditional 401(k) and IRA contributions reduce your federal taxable income. Many states, including Missouri, also exclude these contributions from state taxable income, reducing both bills simultaneously.
- Claim all applicable deductions and credits. Many states offer credits for property taxes, dependent care, education, and energy-efficient home improvements that are separate from federal credits. Check the Missouri Department of Revenue for Missouri-specific credits.
- Consider the standard vs. itemized deduction. Some states allow itemized deductions even if you take the federal standard deduction — or have their own standard deduction amounts that differ from federal. Checking the state-specific rules can sometimes reveal additional savings.
What to Do After Getting Your Estimate
- If you expect to owe money, consider adjusting your W-4 withholding or making a state estimated tax payment to avoid a balance due at filing time.
- If you are self-employed, your SE tax is separate — use our self-employment tax calculator to estimate that additional obligation.
- To verify your numbers, use the official Missouri tax forms or consult a qualified tax professional familiar with Missouri tax law.
