Missouri capital gains tax changes dramatically in 2025 due to new legislation that eliminates state income tax on capital gains for individual taxpayers. This exemption applies broadly and removes capital gains from Missouri taxable income, making Missouri capital gains tax effectively zero for individuals.
What Are Capital Gains?
Capital gains arise when you sell a capital asset for more than your adjusted basis. Missouri follows federal rules to define what constitutes a capital asset and how gain is computed. Typical assets include real estate, securities, digital assets, business interests, and investment property.
There are two basic types:
- Realized Capital Gains: Gains recognized when you sell an asset.
- Unrealized Capital Gains: Paper gains that exist only while you hold the asset; these are not taxed until sold.
Under Missouri’s 2025 rules, realized capital gains are not taxed at the state level, regardless of whether they are short-term or long-term.
Long-Term vs. Short-Term Capital Gains
Federal law distinguishes between long-term and short-term gains, which heavily affects federal tax planning.
- Short-Term Capital Gains: Assets held 1 year or less; taxed federally as ordinary income.
- Long-Term Capital Gains: Assets held more than 1 year; taxed federally at 0%, 15%, or 20%.
Missouri does not tax either type beginning in 2025.
Federal Capital Gains Tax Rates in 2025
Short-term gains follow federal ordinary income brackets:
| Taxable Income (Single Filers) | Taxable Income (Married Filing Jointly) | Tax Rate |
|---|---|---|
| $0 to $11,925 | $0 to $23,850 | 10% |
| $11,925 to $48,475 | $23,850 to $96,950 | 12% |
| $48,475 to $103,350 | $96,950 to $206,700 | 22% |
| $103,350 to $197,300 | $206,700 to $394,600 | 24% |

| $250,525 to $626,350 | $501,050 to $751,600 | 35% |
| $626,350 or more | $751,600 or more | 37% |
Long-term capital gains follow reduced federal rates:
| Taxable Income (Single Filers) | Taxable Income (Married Filing Jointly) | Tax Rate |
|---|---|---|
| $0 to $48,350 | $0 to $96,700 | 0% |
| $48,350 to $533,400 | $96,700 to $600,050 | 15% |
| $533,400 or more | $600,050 or more | 20% |
Other federal rules include:
- Depreciation recapture at 25%
- Collectibles at 28%
- NIIT at 3.8% for high-income taxpayers
These federal rules continue to apply even though Missouri no longer taxes capital gains.
Missouri Capital Gains Tax in 2025
On July 10, 2025, Missouri passed legislation that eliminates capital gains from state taxable income for individuals.
Key points for Missouri taxpayers:
- Capital gains are fully exempt from Missouri income tax beginning in 2025.
- Applies to both short-term and long-term gains.
- Applies to all types of capital assets, including:
- Stocks and securities
- Real estate
- Business sales
- Cryptocurrency
- Investment property
- Tangible and intangible assets
- Missouri still follows federal recognition rules for determining the amount of gain, but the gain is not taxed by the state.
- There are no income thresholds or phase-outs for the state exemption.
- There are no local income taxes in Missouri that apply to capital gains.
Missouri’s full exemption makes it one of the most capital-gains-friendly states in the country starting in 2025.
Case Study: How Missouri Capital Gains Tax Applies
A Missouri resident earns $140,000 in wages and realizes a $70,000 long-term capital gain from selling stock.
Federal impact:
- The $70,000 gain is taxed at the 15% long-term federal rate.
- Federal tax owed = $10,500.
Missouri impact:
- Missouri exempts capital gains in 2025.
- State tax owed = $0.
Combined total tax:
$10,500, plus NIIT if applicable.
If the same $70,000 gain occurred in 2024, Missouri would have taxed it at 4.8%.
Strategies to Reduce Capital Gains Taxes
Since Missouri exempts capital gains entirely at the state level starting in 2025, planning primarily focuses on federal tax management.
- Hold assets long enough to qualify for federal long-term capital gains rates.
- Harvest losses to reduce federal taxable gain.
- Use installment sales to avoid federal bracket spikes.
- Use 1031 exchanges to defer federal gains on real estate.
- Monitor timing — delaying a sale until 2025 saves Missouri state tax completely.
Conclusion
Missouri capital gains tax in 2025 is eliminated for individuals, making Missouri one of the most favorable jurisdictions for realizing capital gains. While federal long-term and short-term rules still apply, Missouri’s complete exemption dramatically reduces total tax liability for many taxpayers. Strategic timing, long-term holding, loss harvesting, and federal deferral tools can further reduce the remaining federal burden.
