Missouri uses a 4.7% top rate state income tax structure. Like most states, Missouri starts its calculation from your federal Adjusted Gross Income (AGI), then applies state-specific adjustments — subtracting income Missouri excludes from taxation (such as certain pension or Social Security income) and adding back any income Missouri taxes that the federal government does not. After adjustments, the Missouri standard deduction is applied, then the 4.7% top rate is applied to arrive at state taxable income.
Missouri income tax is collected through employer paycheck withholding for W-2 employees and through quarterly estimated payments for self-employed residents and those with significant non-wage income. The Missouri state return is generally due April 15, aligned with federal returns. Part-year residents and nonresidents who earn income sourced in Missouri must also file a Missouri return for that income portion.
Your Missouri state income taxes are deductible on your federal Schedule A as part of the SALT (State and Local Tax) deduction, capped at $40,400 in 2026 under OBBBA. At the 22% federal bracket, paying $1,540 in Missouri state income tax generates approximately $338 in federal tax savings, reducing the true net cost of your Missouri taxes to about $1,202 for itemizing taxpayers.
Jordan is a single filer earning $75,000 in Missouri. This shows how federal and Missouri state income tax are calculated together.
Moving to a no-income-tax state (Texas, Florida, Nevada, or Wyoming) would save Jordan approximately $1,540/year ($128/month) in state income taxes. However, no-income-tax states often fund services through higher property taxes, sales taxes, or other fees, so a complete comparison requires evaluating all taxes together, not just income tax.
Missouri Tax Rate and Annual Filing
Missouri residents earning above the state filing threshold must file a Missouri income tax return annually, typically due April 15. The 4.7% top rate applies after Missouri-specific deductions and any state tax credits. Employers withhold Missouri state income tax from employee paychecks throughout the year using Missouri withholding tables, and any balance owed or refund due is settled when the annual state return is filed. Self-employed Missouri residents make quarterly estimated payments to the state in addition to their federal quarterly estimated tax payments.
Federal SALT Deduction Reduces Net State Tax Cost
State income taxes paid in Missouri reduce your federal taxable income through the SALT deduction (capped at $40,400 in 2026 under OBBBA). For a Missouri resident in the 22% federal bracket paying $1,540 in state income tax, the SALT deduction recovers approximately $338 in federal taxes, so the true after-federal-benefit cost of Missouri state income tax is about $1,202. This offset only benefits taxpayers who itemize deductions on federal Schedule A rather than taking the standard deduction.
Total Tax Burden: State Income Tax Is One Piece

Property taxes, local income taxes (in some Missouri cities and counties), and state and local sales taxes also contribute to your overall cost of living. When comparing Missouri to other states, evaluate all tax types together rather than income tax in isolation.
