1031 Exchange in Montana
Montana conforms to the federal 1031 like-kind exchange rules, so a properly structured exchange defers Montana income tax on the same timeline as federal tax. But Montana is a clawback state: under Mont. Admin. R. 42.2.308, when you relinquish Montana property in a 1031 exchange for out-of-state replacement property, Montana defers the Montana-source gain and requires it to be reported when that gain is later recognized federally. Montana has no general sales tax and, by constitutional prohibition, no real estate transfer tax.
Fast Facts
- State Income Tax on Capital Gains
- Montana taxes net long-term capital gains under a separate two-rate schedule of 3.0% and 4.1% (MCA 15-30-2103), lower than the ordinary income rates of 4.7% and 5.9% that apply to short-term gain and other income.
- Conforms to Federal 1031
- Yes. Montana follows the federal like-kind exchange rules, so a valid federal 1031 deferral is generally recognized for Montana income tax purposes on the same timeline.
- Clawback Rule
- Yes. Under Mont. Admin. R. 42.2.308, Montana-source gain deferred by exchanging Montana property into out-of-state property is reported to Montana when it is later recognized for federal purposes.
- Non-Resident Withholding
- Montana's Real Estate Backup Withholding Act requires 2.5% withholding on the sales price of Montana real estate, but a transfer is exempt when the property is relinquished in a 1031 exchange in which gain or loss is not recognized.
- Transfer Tax & Sales Tax
- Montana has no general statewide sales tax, and Article VIII, Section 17 of the Montana Constitution prohibits any state or local tax on the sale or transfer of real property. A Realty Transfer Certificate is filed with the deed.
Why Montana Is Different: The Clawback Rule
Most states that conform to Section 1031 let the deferral ride and tax the gain later, if and when it is recognized on a taxable state return. Montana takes a more explicit approach for one specific fact pattern: relinquishing Montana real property in a 1031 exchange for out-of-state replacement property.
Montana honors the deferral at the time of the exchange, so you do not pay Montana tax when you close. What Montana does not do is give up its claim to the gain that accrued while the property was located in Montana. Under Mont. Admin. R. 42.2.308 — titled “Nonresident calculation of Montana source income realized and recognized when Montana property is relinquished as part of a Section 1031 exchange” — the gain realized on the Montana property retains its Montana-source character. Recognition is deferred while like-kind property is held, but the deferred Montana-source gain must be reported to Montana “if and when the gain is recognized for federal income tax purposes.” The amount Montana can reach in that later year never exceeds the gain recognized federally.
The practical effect: if you sell Montana investment property and exchange into another state, you have effectively kept a Montana tax obligation attached to that deferred gain. When you eventually sell the out-of-state replacement property in a taxable transaction, the deferred Montana-source portion becomes reportable Montana income — even if you have long since moved your capital and your residency elsewhere. Montana investors planning a cross-state exchange should model this eventual Montana add-back into their long-term tax picture, not just the federal deferral, and keep records that let them trace the Montana-source gain forward across the exchange.

Montana Tax Rate and Sales Tax Context
Montana applies a separate, lower rate schedule to net long-term capital gains. Under MCA 15-30-2103, net long-term capital gains are taxed at 3.0% up to a filing-status threshold and 4.1% above it, reduced by nonqualified taxable income — so gain from selling long-held investment real estate is generally taxed more lightly than ordinary income. Montana’s ordinary individual income tax uses a two-rate structure of 4.7% and 5.9%, with the 5.9% top rate applying above the bracket threshold; short-term gain and boot that does not qualify as long-term capital gain fall under those ordinary rates. Because rates and thresholds change year to year — and Montana has enacted further reductions taking effect in 2026 that lower the top ordinary rate to 5.65% — always confirm the current figure on the Montana Department of Revenue rate tables before you plan a transaction.
On the transaction side, Montana is unusually light. The state has no general statewide sales tax, and Article VIII, Section 17 of the Montana Constitution flatly prohibits the state or any local government from imposing any tax — including a sales tax — on the sale or transfer of real property. That means there is no real estate transfer tax, deed tax, or documentary stamp tax on Montana conveyances. What Montana does require is a Realty Transfer Certificate (Form RTC), filed with the county clerk and recorder when a deed is recorded; it is an informational filing, not a tax. The practical result is that Montana investors typically face far lower friction costs at closing than investors in states with meaningful transfer or documentary-stamp taxes.
Step-by-Step Process
- 1
Engage a Qualified Intermediary Before Closing
For a delayed exchange, you must set up a Qualified Intermediary (QI) before you close on the relinquished Montana property. You cannot take actual or constructive receipt of the sale proceeds — the QI holds the funds. Structuring the sale as a valid 1031 exchange in which gain is not recognized also exempts the transfer from Montana's 2.5% real estate backup withholding.
- 2
Sell the Relinquished Property
Close the sale of your relinquished Montana property with the QI receiving the proceeds. A Realty Transfer Certificate (Form RTC) is filed with the deed at the county clerk and recorder. Report the disposition on federal Form 8824.
- 3
Identify Replacement Property Within 45 Days
You have 45 calendar days from the sale of the relinquished property to formally identify potential replacement property in writing, following the federal identification rules (such as the three-property rule or 200% rule).
- 4
Close on Replacement Property Within 180 Days
You must acquire the replacement property within 180 calendar days of the sale (or your tax-return due date including extensions, if earlier). Only real property held for investment or business use qualifies under post-2017 federal law.
- 5
Report Federally — and Track the Montana Clawback
Report the exchange on federal Form 8824. If your replacement property is outside Montana, keep records that trace the deferred Montana-source gain forward, because Mont. Admin. R. 42.2.308 requires that gain to be reported to Montana when it is later recognized federally on the eventual disposition of the out-of-state property.

Frequently Asked Questions
Yes. Montana recognizes the federal like-kind exchange rules, so a properly structured 1031 exchange defers Montana income tax on the same timeline as federal tax. The key wrinkle is that if you relinquish Montana property in an exchange for out-of-state replacement property, Montana tracks the deferred Montana-source gain and recaptures it later under its clawback rule (Mont. Admin. R. 42.2.308).
Under Mont. Admin. R. 42.2.308, when Montana real property is relinquished in a 1031 exchange for property located outside Montana, the gain retains its Montana-source character and is deferred at the time of the exchange. When the out-of-state replacement property is later sold in a transaction where gain is recognized for federal purposes, the deferred Montana-source amount becomes reportable Montana income, up to the gain recognized federally. That is why cross-state exchanges keep a Montana tax obligation attached to the deferred gain.
Montana's Real Estate Backup Withholding Act requires 2.5% withholding on the sales price of Montana real estate, but the transfer is exempt when the property is being relinquished in a 1031 exchange in which gain or loss is not recognized. Sales under $250,000 and a transferor's principal residence are also exempt. Confirm the exemption applies to your structure before closing.
Montana taxes net long-term capital gains under a separate schedule of 3.0% and 4.1% (MCA 15-30-2103). Short-term gain and other income are taxed at Montana's ordinary rates of 4.7% and 5.9%. Boot in a partial exchange, or gain from a failed exchange, is taxed according to whether it qualifies as net long-term capital gain or as ordinary income. Check the Montana Department of Revenue rate tables for the current thresholds.
No. Article VIII, Section 17 of the Montana Constitution prohibits the state and local governments from imposing any tax on the sale or transfer of real property, so there is no transfer tax, deed tax, or documentary stamp tax. Montana also has no general sales tax. A Realty Transfer Certificate (Form RTC) must be filed with the deed, but it is an informational document, not a tax.
