Capital Gains on Your Foreign Home When You Renounce

“What happens to my house?” is one of the most common questions people ask when they start thinking seriously about renouncing. And it’s one of the questions most likely to produce unnecessary panic, because the answer, for the majority of people, is: nothing. Nothing happens to your house.

But the minority of cases where something does happen? That’s where the numbers get significant. So let’s walk through exactly how US capital gains rules apply to your foreign home when you expatriate, who actually owes tax, and how to structure the timing so you don’t pay more than you need to.

The Threshold Question: Are You a Covered Expatriate?

Everything about capital gains on your home — and on every other asset — starts with one question: are you a covered expatriate?

If you are not a covered expatriate (net worth under $2 million, average annual tax under $211,000, and five years of clean tax filings), then renouncing has zero US capital gains consequences. No deemed sale. No exit tax. No reporting requirement beyond the standard Form 8854. Your house, your portfolio, your business — the IRS doesn’t get a parting shot at any of it.

This is the situation most renunciants are in. If your total net worth is well under $2 million, you can stop worrying about the deemed sale entirely. Sell your house whenever you want, before or after renouncing, and the only capital gains tax you’ll deal with is whatever your country of residence charges.

If you are a covered expatriate, keep reading. This is where it gets interesting.

The Deemed Sale: How It Works for Your Home

Covered expatriates are treated as if they sold all worldwide assets at fair market value on the day before their expatriation date. This includes your foreign home. The “sale” is fictional — you’re not actually selling anything — but the tax on the fictional gain is very real.

Here’s how the math works for a home:

Fair market value on the day before expatriation: This is what your home would sell for in an arm’s-length transaction. You’ll want a professional appraisal — not a Zillow estimate, not what your neighbor sold for, but an actual valuation you can defend if the IRS asks questions.

Minus your cost basis: What you paid for the home, plus qualifying improvements (renovations, additions — not repairs or maintenance), minus any depreciation you’ve taken.

Equals your unrealized gain. This gain gets included in your total exit tax calculation along with all your other assets.

Suppose you bought a house in London for $400,000 twelve years ago, put $100,000 into renovations, and it’s now worth $900,000. Your basis is $500,000. Your unrealized gain is $400,000. That $400,000 goes into the exit tax pot alongside your portfolio gains, business interests, and everything else.

The $250K/$500K Primary Residence Exclusion

Here’s where the news gets better. The Section 121 primary residence exclusion — the same one that lets US homeowners exclude $250,000 of gain ($500,000 if married filing jointly) when they sell their home — applies to the deemed sale.

To qualify, you need to meet the ownership and use tests: you must have owned and used the home as your primary residence for at least two of the five years ending on the day before your expatriation date. If you’ve been living in the house, you almost certainly qualify.

This exclusion is applied before the $910,000 exit tax exclusion. The combined effect:

Filing Status	Residence Exclusion	Exit Tax Exclusion	Combined Shelter
Single	$250,000	$910,000	$1,160,000
Married Filing Jointly	$500,000	$910,000	$1,410,000

For the London house example: your $400,000 gain is entirely covered by the $250,000 residence exclusion alone. The exit tax exclusion hasn’t even been touched, leaving the full $910,000 available for your other assets.

Even for covered expatriates with expensive homes, the stacking of these two exclusions provides substantial protection. A covered expatriate with a home gain of $800,000 and $600,000 in portfolio gains — $1.4 million total — would owe zero exit tax as a single filer, because the $250,000 residence exclusion and the $910,000 exit tax exclusion together cover the entire amount.

Selling Before vs. After Renouncing

The timing of a home sale relative to your renunciation date matters, and the optimal strategy depends entirely on your covered expatriate status.

If you are NOT a covered expatriate:

Sell after renouncing. Once you’re no longer a US person, the US has no authority to tax gains on your foreign assets. You’ll owe capital gains tax only in your country of residence — and many countries offer their own exemptions for primary residences. Selling before renouncing means reporting the gain on a US tax return and potentially paying US capital gains tax that you could have avoided entirely by waiting.

If you ARE a covered expatriate:

The calculation is more nuanced. You have two paths:

Path A: Sell before renouncing. You recognize the gain while still a US citizen and apply the $250K/$500K primary residence exclusion. The gain is taxed at regular capital gains rates (20% federal, plus 3.8% NIIT for high earners). The advantage: the gain is recognized and taxed on your terms, and it’s no longer an unrealized gain sitting in the exit tax calculation.

Path B: Keep the home and let the deemed sale apply. The gain is included in the exit tax calculation, but you can apply both the residence exclusion and the $910K exit tax exclusion. The advantage: if your total unrealized gains across all assets are below the combined exclusion, you may owe nothing.

Which path is better depends on the total picture — not just your home, but all your assets. If your home is your primary source of unrealized gain and the rest of your portfolio has modest gains, Path B might shelter everything. If you have large gains across multiple assets, selling the home first (Path A) might free up the exit tax exclusion for your other investments.

A cross-border tax professional can model both scenarios with your actual numbers. This is one of the cases where the consultation fee pays for itself several times over.

Country-Specific Angles

Your country of residence has its own capital gains rules, and they don’t care about your US situation. Here’s how a few major expat destinations handle primary residences:

Canada: The principal residence exemption eliminates capital gains tax entirely on your primary home. If you’re a Canadian tax resident selling your Canadian home, you typically owe zero Canadian capital gains tax — regardless of the gain amount. This makes Canada one of the most favorable countries for the “sell after renouncing” strategy.

United Kingdom: The UK offers Private Residence Relief, which exempts your primary home from Capital Gains Tax. However, periods of absence, letting the property, or owning it as a non-resident can reduce the exemption. The rules changed significantly in recent years, and non-residents selling UK property now face CGT obligations that didn’t exist before.

Australia: No exemption on the gain itself, but Australian residents get a 50% CGT discount on assets held for more than 12 months. A $400,000 gain on a home held for 15 years would be taxed on only $200,000. The main residence exemption applies to homes that have been your primary residence throughout the ownership period, but the rules for non-residents have tightened considerably — temporary residents and non-residents may lose the exemption entirely.

Germany: Gains on property held for more than 10 years are completely tax-free. If you’ve owned your German home for a decade, there’s zero German capital gains tax on the sale, regardless of the gain. For shorter holding periods, gains are taxed as ordinary income.

The interaction between US exit tax rules and your country’s domestic rules can create opportunities — or traps. Don’t assume that a tax treaty eliminates double taxation on the deemed sale. Many treaties don’t address the exit tax specifically.

Fair Market Value: Get an Appraisal

If you’re a covered expatriate and the deemed sale applies, you need to establish the fair market value of your home on the day before your expatriation date. This is the number the IRS will use to calculate your gain.

“Fair market value” means the price a willing buyer and a willing seller would agree to, with both having reasonable knowledge of the relevant facts. In practice, for the exit tax, this means a professional appraisal.

Not a tax assessment. Not a real estate agent’s listing opinion. A formal appraisal from a qualified professional that you can submit to the IRS as supporting documentation for your Form 8854.

The appraisal should be dated as close to your expatriation date as possible. Getting one three months before you renounce and another shortly after gives you a defensible bracket. The cost is typically $300–$800 for a standard residential appraisal, depending on the country and the complexity of the property. For a home worth hundreds of thousands of dollars, it’s cheap insurance.

Joint Ownership With a Non-US Spouse

If you own your home jointly with a non-US spouse, only your share is included in the deemed sale calculation. In most jurisdictions, joint ownership implies a 50/50 split, so a home with $600,000 in total gain would attribute $300,000 to you.

This can make a significant difference. If you’re right at the edge of the exit tax exclusion, having your spouse’s half excluded from the calculation might keep you below the threshold entirely.

One caveat: the IRS will look at the substance of the arrangement, not just the title. If you transferred your share to your spouse last week in an obvious attempt to reduce the deemed sale, expect scrutiny. Legitimate long-standing joint ownership is fine. Last-minute reshuffling is not.

Putting It All Together

The fear around “capital gains on my home” is one of the most common concerns people have when they start researching renunciation. The reality is more nuanced — and, for most people, much less scary — than the fear suggests.

If you’re not a covered expatriate, your home is irrelevant to the US tax picture. Sell it whenever you want. The US gets nothing.

If you are a covered expatriate, the combination of the residence exclusion and the exit tax exclusion shelters up to $1.16 million in gain ($1.41 million if married filing jointly). For most homeowners, even in expensive markets, that covers the entire gain.

The people who face real exposure are covered expatriates with homes that have appreciated by more than $1 million beyond their basis — and who also have significant gains in other assets competing for the $910K exclusion. That’s a real but relatively narrow group.

For everyone else: get your numbers, understand your covered expatriate status, check your country’s domestic exemptions, and make the timing decision based on actual math rather than forum anxiety. The consultation with a cross-border tax professional — the same one you’ll need for the overall renunciation process — should include a specific discussion of your home.

Your house is probably fine. But “probably” is worth confirming with real numbers.
