What happens to capital gains tax when you sell foreign real estate

Capital gains tax on foreign property depends on your citizenship and where you live when you sell, not where the property is located. If you are a U.S. citizen or resident alien, you owe federal capital gains tax on the profit from selling foreign real estate, just as you would on U.S. property. The country where the property sits may also tax the sale — this is separate from what you owe the IRS.

The strategies people use to reduce this tax are legal but narrow. They involve timing the sale, using losses to offset gains, or in rare cases, holding the property long enough to may have access to for a lower tax rate. There is no blanket exemption for foreign property, and the IRS requires you to report the sale on your tax return regardless of where you live now.

The most common mistake is assuming that selling foreign property outside the U.S. means you do not owe U.S. tax. That is false. The second mistake is not accounting for tax paid to the foreign country — you may be able to claim a credit for it, which reduces what you owe the IRS, but only if you report both correctly.

Key Takeaways

  • U.S. citizens and resident aliens owe federal capital gains tax on foreign property sales, and the foreign country may tax it too.
  • Long-term capital gains (property held over one year) are taxed at lower rates than short-term gains, and this applies to foreign property the same way.
  • You can offset capital gains with capital losses from other investments or property sales in the same year.
  • Tax paid to a foreign country may reduce your U.S. tax bill through the foreign tax credit, but you must report it correctly on Form 1118.
  • Timing the sale across two tax years, using a 1031 exchange, or holding until death may lower or defer tax, depending on your situation.

How long-term versus short-term capital gains rates work

The tax rate on your profit depends on how long you owned the property before selling. If you held it for more than one year, it is a long-term capital gain and taxed at 0%, 15%, or 20% depending on your income. If you held it for one year or less, it is a short-term capital gain and taxed as ordinary income — meaning your regular tax bracket applies, which is usually higher.

This rate structure is identical for foreign and U.S. property. A property you bought in Mexico five years ago and sold this year qualifies for long-term rates. A property you bought and sold within the same calendar year does not. The IRS counts the holding period from the date you acquired it to the date you sold it.

For someone in the 24% ordinary income bracket, the difference is significant: a $100,000 gain taxed as short-term costs $24,000 in federal tax, while the same gain taxed as long-term costs $15,000. Waiting a few months to cross the one-year threshold can save thousands, and this is one of the few legal moves available to most sellers.

Using capital losses to reduce what you owe

If you have losses from other investments or property sales in the same year, you can subtract them from your capital gains. This is called loss harvesting and it is one of the few concrete ways to lower your tax bill. A $50,000 gain on foreign property minus a $20,000 loss on stocks means you report only $30,000 in net capital gains.

The loss must be a real loss — a property or investment you actually sold for less than you paid. Unrealized losses (property that is worth less but you have not sold) do not count. You can carry unused losses forward to future years if your losses exceed your gains in the current year, but the rules are complex and depend on your income level.

This strategy works best if you have other investments you were already planning to sell at a loss. It is not a reason to sell a losing property just to offset a gain, because you still lose money overall — you simply reduce the tax on the gain.

Foreign tax credits and how they reduce your U.S. bill

Most countries tax property sales within their borders. If you paid capital gains tax to the country where the property is located, you may be able to claim a foreign tax credit on your U.S. return, which reduces your federal tax dollar-for-dollar (up to the amount of U.S. tax owed on that income). This prevents double taxation on the same gain.

To claim the credit, you file Form 1118 (Foreign Tax Credit) with your U.S. tax return and report the tax you paid to the foreign country. The credit is limited to the U.S. tax you owe on foreign-source income, so if the foreign country taxed you at a higher rate than the U.S., the excess credit cannot be used (though it can sometimes be carried back or forward). If the foreign country taxed you at a lower rate, you owe the difference to the IRS.

Example: You sell a property in Canada and owe $30,000 in Canadian capital gains tax. Your U.S. federal tax on the same gain is $20,000. You can claim a $20,000 credit against your U.S. bill, reducing it to zero. The remaining $10,000 in Canadian tax is your cost of doing business in Canada — the U.S. does not refund it.

1031 exchanges and deferring tax on foreign property

A 1031 exchange allows you to sell one investment property and buy another without paying capital gains tax on the sale — you defer the tax until you eventually sell the replacement property without doing another exchange. This works for foreign property in theory, but in practice it is extremely difficult and rarely used.

The rules require that you identify a replacement property within 45 days of selling and close on it within 180 days. The replacement property must be of equal or greater value and held for investment or business use (not personal use). The IRS does not care where the property is located, so a foreign sale can be exchanged for a U.S. property and vice versa.

The real barrier is logistics: you need a may have access to intermediary to hold the proceeds, and most intermediaries are not set up to handle foreign transactions. You also need to find a suitable replacement property in a tight timeframe, which is harder internationally. Most people use 1031 exchanges for domestic property swaps. If you own foreign property and want to explore this, consult a tax professional who handles international transactions.

Holding property until death and the step-up in basis

If you own foreign property when you die, your heirs inherit it at its fair market value on the date of your death — not at the price you paid. This is called a step-up in basis. If you paid $200,000 for a property and it is worth $500,000 when you die, your heirs' basis is $500,000. If they sell it immediately, they owe no capital gains tax.

This is not a strategy you can control — you cannot time your death — but it is worth understanding if you are planning your estate. The step-up applies to foreign property the same way it applies to U.S. property, and it can eliminate a large tax bill for your heirs. Some countries have inheritance taxes that may offset this benefit, so the math depends on both U.S. and foreign law.

If you are considering holding foreign property specifically to avoid capital gains tax, weigh this against the costs of ownership: property taxes, maintenance, currency risk, and the difficulty of managing property remotely. The tax savings may not justify the expense.

Reporting foreign property sales and FIRPTA rules

When you sell foreign real estate, you must report the sale on your U.S. tax return using Schedule D (Capital Gains and Losses) and Form 8949 (Sales of Capital Assets). You also report it on your FBAR (Foreign Bank Account Report) if the proceeds are held in a foreign account, though the FBAR is about accounts, not property sales themselves.

If you are a foreign national (not a U.S. citizen or resident alien) selling U.S. real estate, FIRPTA (Foreign Investment in Real Property Tax Act) requires the buyer to withhold 15% of the sale price and send it to the IRS. FIRPTA does not apply to foreign nationals selling foreign property, and it does not apply to U.S. citizens selling foreign property. It is a U.S.-specific rule.

The reporting requirement exists even if you do not owe tax (for example, if you sold at a loss). Failure to report can result in penalties and interest, and the IRS can assess tax years back. If you are unsure whether you reported correctly in past years, a tax professional can help you file amended returns.

Frequently Asked Questions

Can I avoid capital gains tax by renouncing my U.S. citizenship?

No. The U.S. has an exit tax that applies to certain former citizens who renounce citizenship. If you renounce and have substantial assets (over $2 million or average annual tax over $190,000 for the prior five years), you owe tax on the gain as if you sold all your property on the day before you renounce. This applies to foreign property too.

What if I sell foreign property but do not report it?

The IRS can assess tax, penalties, and interest going back several years. If the foreign country reported the sale to the IRS (many do through information-sharing agreements), the IRS will likely find out. Penalties for not reporting can exceed the tax itself. If you have unreported sales, consult a tax professional about filing amended returns.

Does the foreign country's capital gains tax rate matter?

Yes, because it affects how much foreign tax credit you can claim. If the foreign country taxes at a higher rate than the U.S., you cannot recover the excess. If it taxes at a lower rate, you owe the difference to the IRS. The foreign tax credit prevents double taxation but does not eliminate it if rates differ.

Can I split the sale across two years to lower my tax bracket?

Only if the buyer and you agree to a delayed closing or installment sale. A standard sale closes in one year and all gain is recognized in that year, regardless of your tax bracket. An installment sale spreads the gain over multiple years as you receive payments, which can lower your bracket each year. This requires the buyer's agreement and has other tax consequences — consult a tax professional before structuring it this way.

What if the foreign country does not have a tax treaty with the U.S.?

You can still claim a foreign tax credit for tax paid to that country, but the rules are more complex and the credit may be limited. Tax treaties simplify the process and often provide lower withholding rates. If you sold property in a country without a treaty, a tax professional can help you determine what credit you are may have access to to claim.
