Expats Tax Services


Expats who temporarily move abroad may face not only the complexity of a foreign tax system; they may also remain liable to some taxes at home. Hence International Tax Planning is essential to avoid unnecessary double taxation.

For most of our clients, the most valuable advice provided by us is based on our deep understanding of tax systems in various countries, enabling us to point out the interaction between the country of residence and country of domicile (often in Common Law Jurisdictions). In any way it is possible to end up in a Tax Residency in one or more countries, triggering Tax Liabilities in each country.

Through our scope of work in International Taxation we offer a seamlessly integrated second to none international and local tax advice – always backed up through local partners. We cover the full range of Taxation – Income Tax, Capital Gains Tax, Gift & Inheritance Tax and Wealth Tax.

Speak to us prior to moving abroad to discuss the complexity of Tax Residency.


Due to the complexity of Tax Laws, an “out of the box” offer and advice is almost impossible. As a consequence we will follow up a personal and individual approach, making our advisory services suit fit your personal circumstances.

Our dedicated Tax Services will cover the full range of personal tax requirements, even if even your tax status and/or residency spans two, three or more countries in Europe, the UK and abroad.

Please find out more about the range of Tax Services we provide down below in the accordion boxes. Furthermore, we have separate parts of the website dedicated to “Inheritance & Succession”, Tax Planning and “Trusts & Estates”.

You can always stop by the Office – appointment required – to speak about your needs. We are pleased to discuss your situation and requirements.


Different countries have their own tax laws. If you are a resident in one country and have income and gains from another, you may have to pay tax on the same income in both countries – or none of them. DTA – Double Taxation Agreements aim to avoid ‘double taxation’ or double non-taxation.

For example, an individual who is resident in Belgium, but has rental income from a property in another country, may have to pay tax on the rental income in both in Belgium and that other country.

To avoid double taxation (and of course a double non-taxation), many countries entered into Tax Treaties (DTA – Double Taxation Agreements), mainly based on international OECD-Standards.


Therefore it is important to plan a tax structure BEFORE entering into any agreements abroad that may trigger tax issues.
