Cross-border succession planning: passing wealth without a tax disaster

Zero Tax · Updated July 2026 · 8 min read

A family with property in two countries, investment accounts in a third and a business in a fourth discovered, when the head of the family died, that each asset opened its own process: a notary here, a probate lawyer there, an inheritance tax nobody had planned for. The wealth had been built well. The succession had not. And that difference cost time, money and family conflict that could have been avoided entirely.

Why cross-border succession is different

When all your wealth sits in one country, inheritance follows a single law and a single tax authority. When it is spread across countries, three layers collide that rarely line up: which law governs the succession of each asset, which country taxes it, and what process must be opened in each place to transfer it. Real estate is usually taxed and governed by the country where it sits, whatever the owner's residence. A financial account may follow the residence or domicile of the deceased. A company follows the law of the country where it was formed.

The result, without planning, is that heirs open parallel processes in several countries, sometimes under contradictory rules, and pay inheritance taxes that could have been reduced or avoided with structure set up in advance.

Where the tax appears

Asset typeTypical inheritance tax rule
Real estateUsually taxed where it is located, at that country's rate
Accounts and investmentsOften by residence or domicile of the deceased or heir, depending on the country
Company sharesBy the law of the country where the company was formed
Assets in a trust or foundationUnder the rules of the vehicle, if properly set up

Some countries have no inheritance tax at all; others charge substantial rates and reach assets located within their borders regardless of where the deceased lived. That is where a family with real estate in a high-inheritance-tax country gets an unwelcome surprise. The specific rates and rules are confirmed against current law in each country involved.

The detail almost nobody weighs: the most expensive problem in cross-border succession is often not the tax, it is the fragmentation. Opening probate in three or four countries, with documents that must be translated, apostilled and validated in each, can take years and freeze the assets while it grinds on. A structure that consolidates ownership of the assets before the event turns several processes into one, which is frequently worth more than any single tax saving.

The tools that bring order

Cross-border succession planning is not one instrument but a combination chosen for the case:

Which combination applies depends on where the assets are, the family's tax residence, and current law. There is no single recipe, and copying another family's structure without that diagnosis is exactly how the problems are created.

The order that works

1. Map the wealth

List every asset, the country it sits in and the succession rule that applies to it today. Without that map, any plan is blind.

2. Consolidate where it helps

Group assets under holding entities to reduce the number of processes and, where it applies, the tax charge.

3. Choose the succession vehicle

Decide whether a trust, a foundation, coordinated wills or a combination fit the family's residence.

4. Document during life

Put everything in writing, coherent and current, so the succession executes clear rules instead of improvising after the event.

Why anticipation is everything

Cross-border succession is planned during life or it is not planned at all. After the event, heirs can only administer what was left, with the options already closed and the taxes already triggered. With years of runway, ownership can be reorganised, the right vehicle chosen and everything documented calmly. If you hold wealth in more than one country, that work is what separates an orderly transition from a multi-year dispute.

Frequently asked questions

Which country taxes an inheritance when the assets are in several countries?

It depends on the asset and the countries involved. Real estate is usually taxed where it is located; financial accounts may follow the residence or domicile of the deceased or heir. With assets spread across countries, several rules can apply at once, which is why planning ahead prevents a double charge. The specific rates are confirmed against current law in each country.

What is the biggest risk in cross-border succession?

Often it is not the tax rate but the fragmentation. Assets in several countries can open a separate probate in each, with documents that must be translated, apostilled and validated locally, which can take years and freeze the assets. Consolidating ownership before the event can turn several processes into one.

Do trusts or foundations help with cross-border succession?

They can help significantly, because assets can pass under the rules of the vehicle rather than opening probate in every country where property sits. But they only work if set up correctly, coherently with the family's residence, and against current law. Poorly built, they create more problems than they solve.

When should I start cross-border succession planning?

Before it is urgent. It works when done years in advance, during life, with clean documentation. Done in a hurry or after an event, the options shrink and the costs rise. If you hold wealth in more than one country, it is already time to organise it.
