Missouri Capital Gains Tax on Real Estate: What Investors Need to Know

On July 10, 2025, Missouri became the first state in the United States to completely eliminate individual state capital gains taxes while maintaining a standard income tax. Governor Mike Kehoe signed House Bill 594 into law, and the exemption applies retroactively to January 1, 2025.

For real estate investors, this is not a minor policy adjustment. It fundamentally changes the math on flips, long-term holds, and portfolio liquidations — and it makes Missouri one of the most tax-competitive real estate markets in the country.

What the Law Actually Does

Under HB 594, individual taxpayers and pass-through entity members can deduct 100% of capital gains reported on their federal income tax returns when calculating Missouri Adjusted Gross Income. The deduction applies to both short-term and long-term gains from:

• Investment real estate (rentals, flips, commercial property)
• Stocks and securities
• Cryptocurrency
• Other capital assets

Before HB 594, Missouri taxed capital gains as ordinary income at its graduated state rate — up to 4.70% for the 2025 and 2026 tax years. On a $200,000 gain from a property sale, the state tax bill ran approximately $9,400. Now it's $0 for individuals and pass-through entities.

The exemption is permanent, not a phase-down or temporary reduction. Missouri has locked in zero state capital gains tax at the individual level indefinitely.

Who Benefits — And Who Doesn't

Full exemption (zero state capital gains tax):

• Individual investors selling real estate
• Single-member LLC members (income flows to personal return)
• Partnership members
• S-corporation shareholders
• Trust beneficiaries (pending outcome of Senate Bill 1575, which proposes extending the exemption to fiduciary returns for trusts and estates)

Partial or no exemption:

• C-corporations: C-corps remain subject to Missouri's flat 4% corporate income tax on capital gains. The corporate capital gains exemption has a trigger mechanism — it phases to zero only after Missouri's top individual income tax rate falls to 4.50% or below. That threshold is projected to be reached between 2026 and 2030. Until then, investors holding real estate in C-corporations do not receive the full exemption.

This creates a clear structural signal: for real estate investment in Missouri, C-corps are the wrong vehicle. LLCs, S-corps, and personal ownership all qualify for the full zero-rate exemption today.

What It Means for Fix-and-Flip Investors

Before HB 594, Missouri flip investors paid both federal capital gains tax (short-term gains taxed as ordinary income at up to 37% federally) and state capital gains at up to 4.70%. A successful flip generating $80,000 in profit could easily produce a combined tax bill of $28,000 or more.

The state portion is now gone. Every flip executed through a pass-through LLC or personal ownership saves 4.70% of the gain in state tax. On a $80,000 flip profit, that's $3,760 in additional after-tax income — effectively a 4.7% improvement in net margin.

For investors running high-volume operations (5 to 15 flips per year), the cumulative benefit is substantial. It also removes a common hesitation about executing deals in Missouri versus neighboring states that still impose capital gains taxes.

What It Means for Long-Term Hold Investors

Investors who have held appreciating Missouri properties — particularly in Kansas City and St. Louis suburbs that saw 105%+ appreciation over the past decade — previously faced a significant tax barrier to portfolio recalibration. Selling an underperforming property triggered both federal and state capital gains, discouraging rational reallocation of capital.

With state capital gains eliminated, investors can now:

• Liquidate C-class properties without state tax drag
• Redeploy capital from single-family rentals into commercial assets or different submarkets
• Harvest gains from highly appreciated properties without the partial deterrent of state tax

The federal capital gains tax (up to 20% long-term, plus 3.8% NIIT for high-income investors) still applies. HB 594 only eliminates the state layer — but removing even a portion of the combined tax friction on large portfolio transactions meaningfully changes the decision calculus.

The 1031 Exchange Question

Missouri investors who previously used 1031 exchanges to defer state-level capital gains taxes need to reconsider the state-level calculus. Since Missouri now charges zero state capital gains tax on individual and pass-through entity sales, the state-level tax deferral benefit of a 1031 exchange has been eliminated.

1031 exchanges still make strong sense for deferring federal capital gains tax (up to 20%) and federal depreciation recapture (up to 25%). These are significant. The mathematics of a 1031 exchange at the federal level alone remain compelling for investors selling large, highly appreciated properties.

What changes is the complexity of partial exchange situations. Previously, receiving "boot" (cash or non-like-kind property from the exchange) triggered both federal and state taxes. Now that the state layer is zero, partial exchanges are simpler to analyze — you only model the federal tax consequences of any boot received.

For Missouri-based Qualified Intermediaries (QIs) facilitating 1031 exchanges, the strict 45-day identification / 180-day closing timeline still governs the federal exchange. The state layer of the QI relationship is now vestigial at the individual level.

Depreciation Recapture: The Exception to Know

HB 594 eliminates state capital gains taxes, but it does not eliminate all taxes associated with property sales. Depreciation recapture — the IRS mechanism that claws back previously claimed depreciation deductions at sale — is taxed federally at a maximum rate of 25% when characterized as Section 1250 unrecaptured gain.

If depreciation recapture is characterized as ordinary income on your federal return rather than as a capital gain, Missouri's ordinary income tax (top rate 4.70%) may still apply to that portion. This is a technical distinction worth reviewing with a tax professional for properties where substantial depreciation has been claimed.

For most residential rental investors, a significant portion of the gain from a long-term hold will be capital gain (eligible for the HB 594 exemption) and a portion will be unrecaptured Section 1250 gain (which may still carry state ordinary income tax). Run the numbers on both components.

Bonus Depreciation and QBI: The Federal Alignment

HB 594 was accompanied by Missouri's permanent alignment with two federal tax provisions under the "One Big Beautiful Bill Act," signed July 4, 2025:

1. 100% bonus depreciation: Permanently restored for qualifying property improvements. Investors can immediately expense qualifying capital expenditures rather than depreciating them over 27.5 years.
2. 20% Qualified Business Income (QBI) deduction: Permanently extended at the state level. Pass-through real estate investors who qualify for the federal QBI deduction under Section 199A can apply the same 20% deduction in calculating Missouri taxable income.

Together with the capital gains elimination, these provisions make Missouri's effective tax rate on real estate investment income among the lowest of any state with an income tax.

Strategic Implications for Missouri Investors

Flippers: Operate through pass-through LLCs or personal ownership to capture the full state capital gains exemption. Avoid C-corp structures until the corporate trigger mechanism resolves.

Long-term hold investors: The state tax barrier to portfolio recalibration is gone. Underperforming assets can now be sold and capital redeployed without the state tax drag that previously discouraged rational liquidations.

Estate planning: Missouri's favorable asset protection trust laws combined with the capital gains exemption make the state increasingly attractive for trust domiciling. Senate Bill 1575 (proposed in 2026) would extend the exemption to trusts and estates filing fiduciary returns — watch for this development.

Out-of-state investors: Missouri now competes directly with no-income-tax states like Texas and Florida for real estate capital at the state level. On a $500,000 property gain, Missouri and Texas are now equally favorable from a state capital gains perspective.

The One-Line Summary

Missouri individual investors and pass-through entity members now pay zero state capital gains tax on real estate. Structure your entities as LLCs, S-corps, or personal ownership — not C-corps — and you have eliminated the state layer of capital gains taxation entirely on every Missouri property sale.
