Every engagement follows the same four-stage process. It begins with understanding your position precisely and ends with every jurisdiction in order.
We establish your country of tax residence, domicile status, income bracket, and the approximate scale of your worldwide estate. These factors determine the framework within which every other question is answered.
Each property jurisdiction is assessed in full: rental tax treatment, capital gains rates, inheritance tax exposure, and the applicable double tax agreement between that country and your country of residence.
We identify every available credit, election, and exemption across all jurisdictions and determine the optimal claim sequence. Excess credits that cannot be used are flagged and the position documented.
We coordinate the preparation and submission of all returns, both local and home-country, with supporting documentation for every treaty position claimed. Annual compliance calendars are maintained across all jurisdictions.
We cover all major property investment destinations. Each jurisdiction operates under its own rules. Understanding them precisely is the basis of any effective cross-border tax position.
Add your property jurisdictions and review the tax treatment of rental income, capital gains, and inheritance in each country, together with the applicable double tax treaty position.

All figures are illustrative estimates based on headline statutory rates and broad income bracket assumptions. Actual liability depends on specific treaty interpretation, elections made, local surcharges, currency, and professional advice. This tool does not constitute tax advice.
This estimate is the starting point. Our advisers will model your exact position, apply treaty reliefs correctly, and manage filings across every jurisdiction.
We advise across six areas of cross-border property taxation, working with a network of registered specialists to ensure every position is properly filed and defensible.
We assess whether the gross or net basis applies in each jurisdiction, identify all allowable deductions, and ensure the most efficient filing method is in place. Where a net election is available — including the US W-8ECI and Canada NR6 — we model the saving before advising on whether to proceed.
Timing, holding periods, and disposal structures materially affect the CGT outcome in every jurisdiction. We model each scenario in detail, including Germany's ten-year exemption, Italy's five-year rule, and FIRPTA obligations for US disposals, before a completion date is agreed.
Real property is taxed in the jurisdiction where it is located at the date of death, regardless of where the owner was resident. We map the inheritance tax exposure in each relevant country and coordinate with specialist advisers on the appropriate mitigation structures.
Applying DTA relief correctly requires an understanding of both countries' domestic law and the specific articles of the applicable treaty. We ensure credits are claimed in the correct order, excess credits are documented, and the treaty position is supportable on review.
Where a holding structure is appropriate, we work with specialist advisers to design and implement arrangements that satisfy BEPS substance requirements, optimise dividend flows through the treaty network, and remain defensible to tax authorities in source countries.
We coordinate the preparation and filing of returns across every jurisdiction where a reporting obligation exists: local property returns, home-country foreign income schedules, and applicable information reporting requirements including FBAR, FATCA, and CRS.
Practical guides for individuals and families who own property in more than one country, whether or not those properties generate rental income.
Most people don't realise their home country can also tax income from an overseas property. Here's how double tax treaties protect you.
French property ownership involves several layers of taxation beyond income tax. Social charges, notional income imputation, and succession duties represent a material additional burden for many non-resident owners.
The country in which your property is located almost always has primary taxing rights over any disposal gain. Your country of residence will typically seek to tax the same gain, subject to treaty relief. The interaction between the two regimes varies considerably by jurisdiction.
Inheritance tax on foreign property is one of the most expensive surprises for families. The rules depend on where the property is, not where you live.
Real situations we've helped navigate. Names changed for privacy.
An Australian couple renting out their French holiday home had been filing correctly in France but had not declared the income in Australia. The double tax treaty provided credit relief, but the Australian filing obligation had been overlooked for five years.
A family based in Dubai owned a Miami apartment. Nobody had told them that non-US persons get only a $60,000 estate tax exemption.
He thought leaving the UK meant leaving his UK tax obligations behind. It didn't. We sorted three years of unfiled returns and removed the penalty risk.
They sold after 9 years and 8 months. Had they waited four more months, a time-based CGT exemption would have saved them €48,000.
The apartment was worth €900,000. With proper structuring in place beforehand, the liability could have been reduced to almost nothing.
Portugal's Non-Habitual Resident regime offered a flat 10% rate on qualifying foreign income. The election is time-critical and must be made in the year of first residence. We identified the opportunity and ensured the application was made within the window.
Questions we are asked regularly by people who own property in more than one country.
In most cases, yes. Countries that tax residents on worldwide income — which includes Australia, Canada, Germany, France, the United States, and many others — require you to declare rental income arising in any country, not only the country where the property is located. Filing a tax return in the property's country does not remove your home-country filing obligation.
The applicable double tax treaty will generally prevent double taxation by allowing a credit for tax already paid in the source country. However, a credit does not remove the requirement to file. Both returns are typically required.
A double tax agreement (DTA) — also called a double tax treaty or tax convention — is a bilateral agreement between two countries that determines which country has the right to tax specific types of income and gains, and how any double taxation that arises is relieved.
For rental income from overseas property, the treaty typically gives the source country (where the property is located) primary taxing rights. Your country of residence then taxes the same income but must give credit for the tax paid in the source country, up to the amount of your home-country tax on that income. The credit prevents double taxation but does not refund excess foreign tax.
Where no DTA exists between two countries, most nations provide unilateral domestic relief, though this is generally less comprehensive than treaty relief.
In most countries, an unoccupied property that is not let does not generate a current income tax liability. However, there are exceptions. France and Spain both impute a notional rental income on second homes during periods when they are not formally let, and require a return to be filed and tax paid on this imputed income.
Regardless of whether the property generates income, two other obligations are worth considering: inheritance tax exposure (which applies in the country where the property is situated at the date of the owner's death, regardless of whether it was ever rented) and the requirement to declare the asset in your home country on any applicable worldwide wealth or information reporting forms.
The country in which the property is located almost always has primary taxing rights over any gain on disposal. Under international tax treaty principles (Article 13 of the OECD Model Convention), real property gains are taxable in the source country as a matter of course.
Your home country will also generally seek to tax the same gain, applying a credit for any CGT paid in the source jurisdiction. The credit is capped at the home-country tax on the gain, so if the source country rate exceeds your home-country rate, the excess is not recoverable.
Several countries offer significant hold-period exemptions that can reduce or eliminate the source-country liability: Germany exempts gains on property held for ten years or more; Italy exempts gains on property held for five years or more; France applies a progressive abatement that reaches full exemption at twenty-two years.
Real property is subject to the inheritance or estate tax of the country in which it is located at the date of death. This applies regardless of where the owner was resident or domiciled. It is one of the most consistent principles in international tax law.
The rates and thresholds vary considerably. France applies progressive rates up to 45% for direct heirs. Spain applies rates of up to 34% with a multiplier for wealthier heirs. The United States applies a 40% rate above a $60,000 exemption for non-resident, non-citizen owners — a particularly severe position for foreign owners of US property. Italy, by contrast, applies a 4% rate above a €1 million threshold for direct heirs, making it one of the more succession-efficient European jurisdictions.
Australia, Singapore, and the UAE currently levy no estate or inheritance tax, which simplifies the succession position for property in those jurisdictions.
Parameter is an introductory and coordination service. We are not a firm of accountants, solicitors, or registered tax advisers, and we do not hold professional regulatory authorisation in any jurisdiction. We do not provide tax advice, legal advice, or financial advice directly.
What we do is help individuals and families who own property in more than one country to understand the landscape of their cross-border tax position and to connect them with the right registered specialists in each relevant jurisdiction. We maintain a network of registered tax consultants, accountants, notaries, and legal advisers across the key property markets, and we coordinate the process on behalf of our clients to ensure that no adviser is working in isolation from the others.
Our registered specialist network handles all formal advice, filings, and legal work, under their own engagement terms and professional indemnity coverage.
The calculator produces indicative estimates based on published statutory rates and broad income bracket assumptions. It is designed to give a directionally useful picture of where tax liabilities may arise across multiple jurisdictions, and to illustrate how double tax treaty credits interact with home-country liabilities.
It is not, and does not purport to be, a substitute for professional advice. Actual tax liabilities depend on specific facts, treaty interpretation, domestic elections, exchange rates, local surcharges, and other factors that the calculator does not capture. The figures it produces should be treated as a starting point for a conversation with a qualified adviser, not as a reliable estimate of a final position.
Joint ownership with a spouse introduces several considerations that differ from sole ownership. For income tax, the rental profit is generally split between the owners in proportion to their legal ownership, and each files separately in both the source country and their home country. If the spouses are resident in different countries, the analysis becomes more complex.
For CGT, each owner is assessed on their proportionate share of the gain. Where spouses are resident in the same country with different marginal rates, there may be planning opportunities around the allocation of ownership interests, though these must be considered in the context of the rules in each jurisdiction.
For inheritance tax, the position depends on the marital property regime applicable to the couple, the law of the country where the property is situated, and any applicable treaty. Some jurisdictions provide full exemption for transfers between spouses; others do not. Taking advice on the succession position when purchasing jointly is advisable.
The immediate obligations depend on the country where the property is located, but in most jurisdictions there are time-limited filing requirements following a death. Italy requires a succession declaration within twelve months of the date of death. France has a filing obligation within six months for deaths in France and twelve months for deaths abroad. Many other countries have their own timelines. Missing these deadlines typically results in penalties, though these are generally manageable if addressed promptly.
Beyond the succession declaration, you will need to establish your cost base for future CGT purposes. In most countries, the relevant base is the market value of the property at the date of death. Obtaining a formal valuation at that date — or as close to it as possible — is important and becomes more difficult to reconstruct as time passes.
If the property is let, you will immediately have a rental income tax obligation in the country where it is situated. If you intend to sell, understanding the CGT position (including any hold-period exemptions available from the date of inheritance) is a priority before committing to a completion date.
The ownership structure has a material impact on the tax treatment at every stage: rental income, disposal, and succession. Personal ownership is the most straightforward for compliance purposes but may not be the most efficient for tax or estate planning.
Holding through a company changes the tax analysis. Rental profits within the company are subject to corporate tax rather than personal income tax rates. Dividends paid from the company to the shareholders attract withholding tax in the source country, reducible by treaty. On death, the heirs inherit shares in the company rather than the property directly, which may change the succession tax exposure depending on how the relevant country treats shares versus real estate for inheritance tax purposes.
The appropriate structure depends on the jurisdiction, the expected holding period, the anticipated eventual exit, and the succession intentions of the owner. There is no universally correct answer. The question should be assessed at the point of acquisition wherever possible.
