1031 Exchange Rules in Missouri
Last reviewed: June 2026. State rules change. Verify current forms before closing.
What Is Different in Missouri
Missouri closes clean for exchangers: no nonresident withholding, no exemption affidavit, and no post-exchange tracking. The top rate has been stepping down through recent legislative cuts and stands at 4.7% for 2026 — still enough on a large gain to make deferral the obvious move.
Does Missouri Conform to IRC Section 1031?
Yes. Missouri follows the federal like-kind exchange rules for real property. A 1031 exchange is an IRS-approved way to sell investment property and buy replacement property without paying tax on the gain right away. If your exchange qualifies for federal deferral, Missouri defers its income tax too. New to exchanges? Start with our 1031 exchange guide.
Your replacement property can be in any state, and Missouri has no claw-back or annual tracking of deferred gain afterward.
Missouri Tax Rate on Real Estate Gains
Missouri’s top income tax rate is 4.7% for 2026. On a $500,000 gain, that can mean up to roughly $23,500 of state tax in addition to the federal bill. A qualifying exchange may defer all of it.
No Withholding at Closing
Missouri imposes no real estate closing withholding on nonresident sellers. There is no exemption certificate to request, no affidavit to sign, and no payment held back at the closing table.
The federal mechanics still govern the exchange itself: a qualified intermediary must hold your sale proceeds, and the 45-day and 180-day deadlines apply. A qualified intermediary is the independent party that holds your sale proceeds during an exchange. WealthBuilder 1031 handles exchanges in Missouri and all 50 states.
Federal Taxes Still Apply
A Missouri exchange defers two layers: federal and state. Here is what a taxable sale looks like without an exchange, using round numbers.
Example: $1,000,000 sale of a Missouri rental. Original purchase $600,000, with $100,000 of depreciation taken, so the adjusted basis is $500,000 and the total gain is $500,000.
| Tax | Calculation | Amount |
|---|---|---|
| Federal depreciation recapture | $100,000 x 25% | $25,000 |
| Federal long-term capital gains | $400,000 x 20% | $80,000 |
| Net investment income tax | $500,000 x 3.8% | $19,000 |
| Missouri state income tax | $500,000 at up to 4.7% | up to $23,500 |
| Total potential tax | up to $147,500 |
Figures are illustrative and rounded. Your rates depend on income, filing status, and basis. A qualifying 1031 exchange may defer the entire amount. Run your own numbers with our 1031 exchange calculators, then confirm them with your tax advisor.
Risks and Things That Go Wrong in Missouri Exchanges
- Assuming no withholding means no state tax. Missouri taxes recognized gain on your return; closing without withholding is a convenience, not an exemption.
- Boot surprises. Cash taken at closing or mortgage relief not offset with new debt or additional cash becomes recognized gain — taxable federally and in Missouri now, not later.
- Failed deadlines. The federal 45-day identification and 180-day completion rules apply with no state extensions. See the IRS rules for 1031 exchanges.
- Deferral is not elimination. The IRS and Missouri will tax the deferred gain when you eventually cash out. Plan the exit, not just the exchange.
Missouri 1031 Exchange FAQs
Does Missouri withhold tax when I sell investment property?
No. Missouri has no nonresident real estate withholding at closing and no exemption form to file.
Can I exchange my Missouri property for property in another state?
Yes. Replacement property can be anywhere in the U.S., and Missouri does not claw back or track the deferred gain afterward.
Do I still need a qualified intermediary in Missouri?
Yes. The QI requirement is federal — your sale proceeds must be held by an independent intermediary, not by you, in every state.
Does Missouri track my deferred gain after the exchange?
No. Missouri has no claw-back rule and no annual reporting tied to deferred exchange gain.
