Missouri state income tax calculator

Estimate Missouri income tax using the graduated brackets (top rate 4.7%).

How this calculator works

Step 1 starts with the Missouri taxable income you already calculated on your return. If you are a part-year resident or nonresident, the tool applies the Missouri income percentage you provide to focus on Missouri-source income.

Step 2 applies Missouri's graduated bracket schedule (0% up to $1,313, top rate above $9,191) to estimate total tax.

Step 3 summarizes the effective and marginal rates so you can see how additional income would be taxed and whether your current estimate matches your expectations.
