In Europe, the rules surrounding tax residency can create significant constraints, especially for families. In the United Kingdom, for example, spending as few as 16 to 46 days with your partner or children can be sufficient to be considered a tax resident. France assesses where your economic interests lie, Spain often presumes residency if your spouse and children live there, and Germany applies rules even if you are renting a property.
In short, many millionaires were previously compelled to keep their families in Europe for social and educational reasons, accepting the often substantial tax burdens as a consequence.
However, the situation is changing rapidly. The UAE now offers high-quality education with an AI-integrated curriculum, safe cities, and numerous family-friendly attractions such as Saadiyat Island, Disneyland Abu Dhabi and the Sphere. Parents increasingly feel their children are better off here, both in terms of safety and education. Consequently, Europe is now losing millionaires, and the future taxpayers they represent. The UAE gains in both capital and talent, while families can still enjoy carefree summer visits to Europe.
How Residence Rules in the UK and EU Complicate Matters for Families
The UK’s Statutory Residence Test (SRT) is a prime example of how complex and stringent these rules can be. If you spend 183 days or more in the UK, you are automatically a UK tax resident. However, even with fewer days, you can still become a resident through “ties” such as having a home, work, family, or available accommodation in the country.
Similar principles apply in other European jurisdictions. If your children attend school in the UK, your partner lives there, or you have a home available for use, you often automatically acquire a “family tie” or “accommodation tie,” which can trigger your tax status more quickly. Even if you personally spend little time in Europe, you may still be considered a resident due to these connections.
In countries like Spain, the rule is straightforward: if your family lives there, you are often automatically deemed a resident. France examines your “centre of economic interests,” looking at the source of your income, your business, investments, etc. In Germany, even renting a property or an extended stay can be sufficient to classify you as a taxpayer. In practice, these rules make it difficult to relocate alone; often, the entire family must move to avoid remaining classified as an ordinary European taxpayer.
These cases demonstrate that tax authorities and courts primarily assess the totality of an individual’s personal and economic interests. Even brief stays or limited use of a property can be enough to maintain tax residency status in a European country.
Why the UAE Has Become (More) Attractive for Families
The UAE is no longer just for singles or businesspeople. Here are reasons why families are emigrating more frequently:
Education & Innovation From the 2025-2026 academic year, artificial intelligence (AI) will become a compulsory subject in public schools, from kindergarten through to Year 12. The curriculum covers concepts such as data, algorithms, ethics, and applications, tailored to each age group. For parents, this means world-class education in Dubai, without the need for their children to remain in Europe for “quality” schooling.
Safety & Quality of Life Relatively low levels of violence, low crime rates, stable infrastructure, and high-quality residential communities make the UAE attractive. Families often report feeling safer here than in some European cities, a factor increasingly cited as a motivation for moving.
Family-Friendly Amenities Attractions such as Disneyland Abu Dhabi, the Sphere, green spaces, beaches, luxury malls, sports facilities, and resorts enable families to build a full and enriching life here without constantly needing to return to Europe.
Fiscal Freedom with Retained Mobility As the UAE levies no income tax, millionaires can manage their capital with far greater freedom. Simultaneously, they can still visit Europe in the summer without tax pressure, provided they carefully manage their European residency status.
Long-Term Impact: Europe Loses, the UAE Gains
When affluent families leave Europe, they take not only their immediate tax contributions but also future generations of taxpayers. Children who grow up in the UAE, advance in its business community or internationally, often do not return to Europe to pay taxes.
Europe is beginning to hollow itself out as a pool for investment and talent, precisely at a time when innovation, knowledge, and capital are crucial. The UAE benefits: the country is attracting capital today while building a talent base for the future.
For millionaires who can make the move, the transition is increasingly logical. And for countries hoping to retain their elite and top talent? The warning is clear: if your tax rules force families to leave, you lose both wealth and your future.
