A 1031 exchange in Maine 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. Maine adds a state tax on the gain and a nonresident withholding step at closing, and because so much Maine property, particularly along the coast, is owned by people who live out of state, that withholding comes up often here. 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 Maine?
Maine taxes the gain as ordinary income, with a top rate of about 7.15%. That sits on top of the federal tax an exchange also 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%.
- Maine's rate of up to about 7.15% on the gain.
Maine conforms to Section 1031, so a properly structured exchange defers both the federal and the Maine tax. The full federal framework is in our main 1031 exchange guide.
Maine's nonresident withholding
When a nonresident sells Maine real estate for more than $50,000, the buyer withholds 2.5% of the sale price and remits it to Maine Revenue Services. It is a prepayment against the Maine tax, not an extra tax, but it pulls cash at the table. In a 1031 exchange you reduce or eliminate the withholding by submitting Form REW-5, a request for exemption or reduction, at least roughly two weeks before closing, supported by your intermediary's documentation. Given how many Maine sellers are nonresidents, filing the REW-5 in good time is a routine but important step here.
Maine 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.
1031 exchanges across Maine markets
Portland and its surroundings carry most of Maine's urban exchange activity, with a growing multifamily and commercial market that has drawn investment from across the Northeast. The defining feature of the rest of the state is its coastal and vacation property: the midcoast, Bar Harbor and Acadia, and towns like Kennebunkport carry high-value second-home and short-term rental property, much of it owned by nonresidents, which is why the withholding step is so common. The western mountains add ski-resort demand around Sunday River and Sugarloaf, and Bangor and Lewiston-Auburn provide lower-cost commercial and multifamily options. Maine property tax is moderate to high and set locally, so confirm the rate for any replacement deal.
Common Maine 1031 exchange mistakes
- Missing the REW-5 filing window, so 2.5% of the sale price is withheld and tied up.
- Underwriting coastal short-term rentals without accounting for local rules and seasonality.
- Taking receipt of the proceeds, or missing the 45-day identification window.
- Trading down or pulling cash out, which creates taxable boot.
Start your Maine 1031 exchange
Set up your exchange before your relinquished property closes, and file the REW-5 in good time, so the withholding is handled and the proceeds never reach your hands. Contact our team to begin, or to talk through a specific deal.
