What Is Missouri Capital Gains Tax Calculator?
The Missouri capital gains tax calculator is an essential state tax estimation tool designed for taxpayers selling stocks, real estate, mutual funds, cryptocurrency, or business assets across the Show-Me State. Capital gains occur when you sell an asset for a higher price than your original cost basis. For tax years beginning on or after January 1, 2025 (including 2025 and 2026), Missouri House Bill 594 created a 100% state income tax subtraction for individual capital gains, effectively rendering state capital gains tax at $0. This calculator allows taxpayers to compare 2025/2026 tax-exempt treatment with historical 2024 rates and accurately project federal tax obligations.

How Missouri Capital Gains Tax Calculator Works
Missouri state capital gains tax is calculated by applying current state deduction rules (100% deduction for tax years 2025 and 2026) or historical rates (up to 4.7% for 2024) to net capital gain, then adding federal capital gains tax liability.
- Sale Proceeds: Gross sale revenue before transaction fees or cost deductions.
- Cost Basis: Original purchase price plus qualifying capital improvements minus depreciation.
- Tax Year: 2025/2026 (100% state deduction) or 2024 (historical ordinary state tax rates).
- Holding Period: Long-term (held > 1 year) or short-term (held <= 1 year).
To calculate capital gains tax in Missouri, first subtract adjusted cost basis from sale proceeds to find net gain.
For 2025 and 2026, Missouri state income tax on this gain is $0 under RSMo Chapter 143.
Federal taxes still apply based on your federal income bracket and asset holding period.
