Why Foreign Property Does Not Qualify for a 1031 Exchange

The 1031 exchange foreign property exclusion is a hard rule in Section 1031 of the U.S. Tax Code: you cannot use a 1031 exchange to defer capital gains by swapping U.S. real estate for foreign property or vice versa. Both properties must be located within the United States.

The Statutory Boundary: U.S. Real Estate Only

Section 1031(a) of the Internal Revenue Code allows an investor to defer capital gains when exchanging property for “like-kind” property of equal or greater value. For decades, “like-kind” was interpreted expansively within the U.S.: an office building could trade for a shopping center, a vacant lot for rental housing. The Tax Cuts and Jobs Act of 2017 narrowed the rule for real property, tightening the definition of like-kind to “real property for real property,” but did not create any carve-out for international swaps.

The IRS has long held that Section 1031 exchanges are limited to property within the United States. A U.S. apartment building and a London flat are not like-kind under Section 1031, even though both are real estate. A farm in Iowa and a ranch in Mexico do not qualify. The statute does not explicitly say “U.S. property,” but the IRS has interpreted the legislative history and longstanding regulatory practice to require domestic property.

This boundary is absolute. There is no sliding scale, no exception for closely comparable properties, no relief for good-faith mistakes. If you close an exchange where the relinquished property or the replacement property is located outside the United States, the entire exchange fails. You owe capital gains tax on the full gain in the year of sale.

What “Like-Kind” Means (and Doesn’t)

Before the 2017 Tax Cuts and Jobs Act, Section 1031 allowed “like-kind” exchanges of personal property and real property. A taxpayer could swap a rental apartment for a parking lot, or even trade real estate for a partnership interest or equipment. The statute was read to mean properties that were of the same broad class or used in the same business.

The 2017 amendment tightened the rule for real property only: as of January 1, 2018, real property can now only be exchanged for real property. A commercial building and a residential lot are still like-kind to each other (both are real property), but real property and personal property (or a business interest) no longer qualify together.

However—and crucially—this tightening did not modify the foreign property rule. The foreign exclusion preexists any modern amendment. The IRS position is that “real property for real property” under the 2017 rules means U.S. real property for U.S. real property.

The Mistake: Assuming Comparable Properties Are Like-Kind

Many investors and even some tax professionals misread the foreign property rule. A common error:

“I own a rental house in California with a $400,000 gain. I want to exchange it for a condo in Cancún, Mexico. Both are residential real property, so they’re like-kind under Section 1031.”

This is incorrect. The properties are not like-kind under Section 1031 because the Mexico property is foreign. The IRS will disallow the exchange. The investor must recognize the $400,000 gain in the year of the Mexican purchase and pay capital gains tax on it (at 15–20% federal long-term rate for most investors, plus applicable state tax and 3.8% net investment income tax if applicable).

The mistake is understandable because “like-kind” seems to be about the nature of the property (residential, commercial, land use), not geography. But Section 1031 has always been interpreted as a domestic tax benefit. Congress never extended it to international real estate.

Tax Consequences of a Failed Exchange

If you sign a contract to exchange U.S. real estate for foreign property and proceed without consulting a tax adviser, you will:

1. Recognize the full gain in the year of disposition. If you sold U.S. property worth $2 million with a $500,000 basis, you owe tax on the $1.5 million gain, regardless of how much you are investing in the foreign replacement.

2. Lose the deferral entirely. There is no partial credit. The fact that you reinvested proceeds in real estate outside the U.S. does not reduce your tax liability.

3. Face the acquired property without a stepped-up basis. Your cost basis in the foreign property is its actual purchase price, not its value at sale. If the foreign property later appreciates and you sell it, you will owe tax on that appreciation as well.

4. Incur potential FIRPTA tax if you later sell the foreign property to a foreign buyer (see discussion below).

Foreign Tax Complications: FIRPTA and Sourcing Rules

Even if you could use a 1031 exchange for foreign property (you cannot), U.S. tax law adds another layer of complexity. If you own foreign real property as a U.S. person, gains from its sale are subject to taxation. The foreign country where the property is located may also tax the gain.

Additionally, if a foreign buyer purchases real property located in the United States, the Foreign Investment in Real Property Tax Act (FIRPTA) requires the buyer to withhold 15% of the sale price. Conversely, U.S. owners of foreign real estate generally cannot use FIRPTA protections—the foreign country’s tax laws apply.

The interplay of U.S. and foreign tax rules, combined with currency risk and political risk, makes foreign real estate investment tax-heavy. A 1031 exchange provides one of the few ways to defer U.S. capital gains on a domestic property swap. Foreign property swaps receive no such relief.

Workarounds and Alternatives

Investors who own U.S. real estate with large gains and wish to diversify internationally have limited options:

• Accept the capital gains tax and reinvest. Pay the tax, net of proceeds, and invest the remainder in foreign property. This is straightforward but costly.

• Hold the U.S. property and borrow against it. Use an equity line or mortgage to fund foreign real estate investment without triggering a sale. You’ll owe interest, but no capital gains tax.

• Donate to charity via a conservation easement (if eligible). In narrow cases, you can get a charitable deduction and avoid capital gains, though regulations now tightly restrict this strategy.

• Use a Delaware Statutory Trust (DST) or TIC within the U.S. only. Some investors use DSTs to simplify management of U.S. real estate, which may qualify for 1031 treatment. This is not a foreign workaround, but it can simplify domestic exchanges.

• Plan a multi-step exchange. Swap U.S. property A for U.S. property B (1031-deferred), then later sell property B and invest proceeds in foreign property (without deferral). You pay tax on property B when you sell it, but you’ve deferred tax on property A.

None of these routes allow you to escape the foreign property exclusion. The rule is a bedrock principle of U.S. tax policy, and the IRS enforces it strictly.
