A 1031 exchange in Montana lets you sell investment real estate and reinvest in like-kind property while deferring the tax on the gain. The federal rules apply the same way everywhere. Montana is an unusual case: it taxes long-term capital gains at a low preferential rate, has no sales tax, and yet is one of only four states that applies a clawback to 1031 exchanges. We act as your qualified intermediary, holding the proceeds and handling the documentation so the exchange holds from sale to closing.

How much is capital gains tax on real estate in Montana?
Montana is one of the few states that taxes long-term capital gains at a lower rate than ordinary income. Where its top income rate runs to roughly 5.65%, long-term capital gains are taxed at a preferential 3.0% or 4.1% depending on the bracket, and Montana also allows a small credit on net capital gains. So the Montana tax on a property gain is comparatively light. It still sits on top of the federal tax an exchange defers:
- Long-term capital gains at 0%, 15%, or 20%, with the 20% rate applying above $545,500 of taxable income for single filers and $613,700 for married couples filing jointly in 2026.
- The 3.8% Net Investment Income Tax above $200,000 of modified adjusted gross income for single filers, $250,000 for married couples.
- Depreciation recapture, taxed as unrecaptured Section 1250 gain at up to 25%.
- Montana's preferential long-term rate of 3.0% or 4.1% on the gain.
Montana conforms to Section 1031, so a properly structured exchange defers both the federal and the Montana tax. The full federal framework is in our main 1031 exchange guide.
The Montana clawback
Despite the low rate, Montana is one of four clawback states, with California, Oregon, and Massachusetts. When you sell Montana property, exchange into replacement property in another state, and later sell that replacement in a taxable transaction, Montana expects to tax the gain that accrued while the property was in Montana, even after a move. The exchange defers the tax at the time it is done, but Montana keeps its claim on the Montana-source gain, so plan for it if you reinvest out of state and keep your records aligned so the deferred gain is tracked.
Montana 1031 exchange rules and timeline
The federal deadlines govern, and they are strict:
- 45-day identification. Identify replacement property in writing within 45 days of the sale.
- 180-day closing. Close within 180 days of the sale, or by your return due date including extensions, whichever is earlier.
- No constructive receipt. Proceeds go to your qualified intermediary, never to you.
- Equal or greater value and debt. Reinvest all net proceeds and match or exceed the relinquished value and debt, or the shortfall is taxable boot.
- Same taxpayer. The entity that sold must be the entity that buys.
Montana does not impose a general nonresident real estate withholding the way many income-tax states do, which simplifies the closing compared with states like Oregon or California.
1031 exchanges across Montana markets
Montana has seen extraordinary demand and price appreciation, much of it from out-of-state buyers, and exchange activity clusters in a handful of markets. The Gallatin Valley around Bozeman has been one of the fastest-growing areas in the country, with ranch, resort, and commercial property, and nearby Big Sky carries ultra-prime resort real estate. The Flathead Valley around Kalispell and Whitefish, near Glacier National Park, draws resort and second-home investment. Missoula adds university-driven multifamily and commercial demand, and Billings, the largest city, anchors agriculture, energy, and medical property. Two local factors belong in your replacement-property math: many resort properties depend on short-term rental income, which is increasingly shaped by local rules, and Montana property taxes have risen sharply after recent residential reassessments and remain a live political issue, so use current figures rather than historical ones.
Common Montana 1031 exchange mistakes
- Overlooking the Montana clawback and assuming the low rate or a move out of state ends the state's claim.
- Underwriting a resort or ranch property on short-term rental income without checking local rules.
- Budgeting property tax at pre-reassessment levels.
- Taking receipt of the proceeds, or missing the 45-day identification window.
