Sell a rental, buy a bigger one, and pay no capital-gains tax this year. That is the promise of a Section 1031 exchange, and it is real, but the rules are unforgiving. Here is how it works for an Alaska investor, in plain English.
What a 1031 exchange actually does
When you sell an investment property at a gain, you normally owe federal capital-gains tax plus depreciation recapture. A 1031 exchange lets you roll the full proceeds into another investment property and defer that tax. Not erase it. The gain follows you into the new property and comes due when you eventually sell without exchanging. Many investors exchange repeatedly and never sell outright, and heirs receive the property at a stepped-up basis.
Alaska has no state income tax, so the only bill you are deferring is federal. That makes the math simpler than in most states but does not make it small: on a $200,000 gain with recapture, the tax can run $40,000 to $60,000.
Both properties must be held for investment
The property you sell and the one you buy must both be held for business or investment use. A duplex you rent out qualifies. Your own home does not. A cabin you mostly use yourself does not. Land held for appreciation does. Since 2018, only real estate qualifies; you cannot exchange into equipment or a business.
“Like-kind” is broad for real estate. A fourplex in Wasilla can be exchanged for a commercial building in Anchorage, raw land on the Kenai, or a triplex in Fairbanks. What matters is investment use, not property type.
The two clocks that blow most exchanges
- 45 days after your sale closes, you must identify the replacement property in writing to your intermediary. You can name up to three properties, or more under value rules.
- 180 days after your sale closes, you must close on the replacement. The 45 days are inside the 180, not added to it.
Neither clock pauses for weekends, holidays, a seller who backs out, or an Alaska winter that slows an inspection. Investors who start looking only after their sale closes run out of time. Start the search before you list.
You cannot touch the money
The sale proceeds must go straight from closing to a qualified intermediary, a third party who holds the funds and buys the replacement on your behalf. If the money lands in your account, even for a day, the exchange fails and the whole gain is taxable. Your title company, your agent, and your CPA cannot serve as intermediary. Line one up before your sale closes; it cannot be added afterward.
To defer everything, trade up
To defer the full gain you must buy a replacement worth at least as much as what you sold and reinvest all the cash. If you buy cheaper or pull cash out, the difference (called “boot”) is taxed. Trading a $450,000 duplex for a $700,000 fourplex defers everything. Trading down to a $350,000 property triggers tax on the $100,000 gap.
Where Alaska investors actually exchange into
The most common move we see is a single rental house exchanged into a two- to four-unit property in the Mat-Su Valley or Anchorage, because those still qualify for residential financing and rents per door are strong. Current inventory is in the Alaska multi-family search. Investors with larger gains sometimes move into five-plus-unit buildings or commercial property, which shift to commercial lending; see our guide to financing multi-family and commercial property in Alaska.
A checklist before you list
- Confirm with your CPA that the property qualifies and estimate the tax you are deferring.
- Engage a qualified intermediary and get their wiring instructions to your title company.
- Start shopping replacements now. Have two or three candidates before your sale closes.
- Get pre-approved for the replacement so the 180-day clock is not spent waiting on a lender.
- Tell your agent it is an exchange. Purchase contracts should include 1031 cooperation language.
