No login required.

How this calculator works

Step 1 calculates your capital gain using cost basis and sale proceeds. If you provide dates, the tool classifies the holding period for reference.

Step 2 adds the gain to your other Missouri taxable income and applies the graduated brackets (marginal 0%) to estimate the incremental tax tied to the sale.

Step 3 shows the Missouri tax impact. The marginal rate reflects the bracket your total income lands in after the gain.

Frequently asked questions

Does Missouri have a special long-term gain rate?

No. Missouri uses the same ordinary income brackets for capital gains and other income.

What if I have a loss?

Losses are displayed for context. Check Missouri’s rules for how losses offset gains.

Do I need to adjust for residency?

Part-year and nonresident filers should prorate Missouri-source income using the allocation percent on their return.
