Do You Have to Declare Your Foreign Property to Your Home Country? A Country-by-Country Guide
Published on: June 26, 2026
This is one of the most-searched and most-misunderstood questions in cross-border real estate, because it actually contains two very different questions:
- Do you have to declare the asset itself, the property, on a form to your home tax authority?
- Do you have to declare the income it produces, the rent and the capital gain when you sell?
For most people in most countries, the answer to the second is yes, and the answer to the first is no. A handful of countries are the exception. And in the background, automatic information-sharing between tax authorities means "they will never find out" is no longer a realistic plan. Here is how it works, country by country.
This is general information, not tax or legal advice. Thresholds and rules change, and cross-border tax is genuinely complex. Confirm your own position with a qualified cross-border tax adviser before relying on anything here.
United States: the property itself is usually not reported
This surprises people, but it is confirmed directly by the IRS: directly held foreign real estate is not a "specified foreign financial asset" and does not have to be reported on Form 8938 (FATCA) or on the FBAR. A personal residence or a rental property you own in your own name abroad is not, by itself, a reportable asset.
The catches are around it, not on it:
- Income is taxable and reportable. Rental income and the capital gain on sale go on your US return, because the US taxes worldwide income.
- Foreign bank accounts trigger the FBAR. If a foreign account, including one you use to collect rent or manage the property, exceeds $10,000 in aggregate at any point in the year, you must file the FBAR (FinCEN Form 114).
- Holding the property through a foreign entity changes everything. If you own it via a foreign company, partnership or trust, that entity becomes reportable on Form 8938 and potentially Forms 5471 or 3520, even though the property held directly would not be. Our FATCA and FBAR guide covers the detail.
Canada: depends on whether it is personal-use or investment
Canada uses Form T1135 (the Foreign Income Verification Statement), required when the total cost of your "specified foreign property" exceeds CAD $100,000 at any time in the year. The key distinction is what counts:
- A personal-use property is excluded. A vacation home you use yourself and do not rent is explicitly not specified foreign property, even if it cost far more than CAD $100,000.
- An investment or rental property is included once your aggregate foreign property crosses the threshold.
Either way, the income and the capital gain are taxable in Canada regardless of T1135. And the penalty for missing a required T1135 is real: CAD $25 per day up to CAD $2,500, even if you owed no additional tax. The form is informational, but the fine for skipping it is not.
United Kingdom: no asset register, but the income is taxed
The UK has no foreign-asset declaration form equivalent to the T1135 or Modelo 720. What it has is worldwide taxation for UK residents. If you are UK tax resident, your foreign rental income goes on your Self Assessment return, and capital gains tax applies when you sell.
The big recent change: the non-domicile regime was abolished from 6 April 2025 and replaced with a residence-based system. The old "remittance" shelter that let some long-term residents keep foreign income outside UK tax is largely gone, which makes accurate reporting of overseas property income more important than it used to be.
Australia: worldwide income, heavy data matching
Like the UK, Australia has no standalone foreign-asset register, but Australian tax residents are taxed on worldwide income. Foreign rental income must be declared, and capital gains tax applies on disposal. The Australian Taxation Office runs extensive international data-matching, so undeclared foreign property income is increasingly likely to surface on its own.
Spain: the country that does want the asset declared
Spain is the clearest example of a country that requires you to declare the property itself. Modelo 720 obliges Spanish tax residents to report foreign assets, including real estate (valued at acquisition cost), where the total in any one category exceeds €50,000. It is purely informational, you do not pay tax through it, but it tells the Spanish tax authority what you hold abroad.
The penalty regime was notorious until the European Court of Justice ruled in January 2022 that the original fines were disproportionate. Spain softened them, but penalties for late or incorrect filing still apply, so it remains a real obligation rather than an optional one. (Crypto, incidentally, now goes on a separate form, Modelo 721.)
The pattern, and why "they won't find out" fails
Step back and the picture is simple. Most countries that tax worldwide income want the income and the gain, not a list of your assets. A minority, with Spain the headline example, also want the asset itself declared on a dedicated form. Canada sits in between, asking for investment property but exempting personal-use homes.
What has changed for everyone is visibility. The Common Reporting Standard (CRS), adopted by more than 100 jurisdictions, automatically shares financial-account information between tax authorities, and the US equivalent, FATCA, does the same for US persons. Combined with registry digitisation and data matching, this means the bank account behind your foreign property, and often the property itself, is increasingly transparent to your home tax authority. Our guide to the CRS explains how the exchange works.
Declaring the asset vs the income, at a glance
| Country | Declare the asset? | Declare rental income? | Declare gain on sale? | Key form |
|---|---|---|---|---|
| United States | No (if held directly) | Yes | Yes | FBAR / Form 8938 (accounts and entities) |
| Canada | Investment property only, over CAD $100k | Yes | Yes | T1135 |
| United Kingdom | No | Yes | Yes | Self Assessment |
| Australia | No | Yes | Yes | Income tax return |
| Spain | Yes, over €50k per category | Yes | Yes | Modelo 720 |
Frequently asked questions
Do I have to tell my home country I bought property abroad?
In most countries you declare the income it earns, not the purchase itself. The main exceptions are countries with dedicated foreign-asset forms, such as Spain's Modelo 720, and Canada's T1135 for investment (not personal-use) property.
Is foreign real estate reported on the FBAR?
No. Directly held foreign real estate is not reportable on the FBAR or Form 8938. But a foreign bank account connected to the property can trigger the FBAR, and property held through a foreign entity changes the answer.
Does owning a vacation home abroad require a Canadian T1135?
No. A personal-use vacation home is explicitly excluded from T1135, even above the CAD $100,000 threshold. A foreign rental or investment property is included.
Will my home country find out about my overseas property?
Increasingly, yes. The CRS shares financial-account data across more than 100 jurisdictions, FATCA does the same for US persons, and tax authorities run data matching. Non-disclosure is a poor strategy.
