Anyone relocating abroad as a private individual faces re-registration, visits to public authorities and the question of the right health insurance. Anyone emigrating as an entrepreneur faces all of that too, plus a range of tax and company-law issues that most emigration guides never cover. The gap between what entrepreneurs expect when leaving and what actually awaits them is considerable.
An entrepreneur’s tax history is more complex than that of a private individual. Shareholdings in corporations, ongoing profit distributions, hidden reserves in company shares, a possible holding structure and unresolved transfer-pricing issues do not simply disappear when you move. They are reassessed.
For private individuals without significant entrepreneurial shareholdings, unlimited tax liability largely ends when they give up their last domestic residence. For entrepreneurs with company shares, most European states impose an exit tax that treats hidden reserves as realised at the time of departure, even if no sale has taken place.
If you do not factor this in early, you can face an unpleasant surprise: ongoing tax liability may end, but the tax burden on past increases in value remains.
Exit taxation on business shares is not a niche rule in a few countries, but a widely used instrument across Europe. France, the Netherlands, Austria, Spain, Belgium and Germany have comparable rules that tax hidden reserves in participations at the time of departure, regardless of whether any actual sale proceeds have been received.
The technical details vary significantly: connecting factors, minimum participation thresholds, valuation methods and deferral rules differ from state to state. As a concrete example: in Germany, a holding of just 1% in a corporation, held at any time within the last twelve years, triggers exit tax under § 6 AStG. The deemed capital gain is taxed at roughly 25%. With a participation showing a book value of €50,000 and an actual value of €2 million, this results in a tax charge of just under €490,000—without a single euro having been received.
Within the EU and the EEA, many of these regimes provide for interest-free deferral as long as the shares are retained. When moving to third countries such as Switzerland, Dubai or the USA, this relief often falls away and the tax becomes due immediately.
From practical advisory experience, the most common misconception is assuming exit tax only affects substantial majority holdings. In reality, minority stakes are sufficient in many states. If you hold interests in several companies, the burdens add up and you can quickly face a seven-figure tax demand that could have been reduced significantly with enough lead time.
A widespread misunderstanding concerns when you are actually tax-resident in a new country. Deregistration in the country of origin is an indication, not proof. What matters is whether genuine, substantive residence has been established in the destination state: with long-term accommodation, actual presence and verifiable connecting factors.
Most states determine tax residence using the concept of habitual abode or the centre of vital interests. Monaco requires demonstrable presence of more than 183 days as well as a permanent home. Switzerland also examines whether your centre of life has in fact been relocated, factoring family, business activities and personal habits into the assessment.
For entrepreneurs this applies all the more. Anyone moving their residence to a tax-attractive state while still effectively running their operating business from the country of origin—working there regularly and maintaining their customer base there—risks ongoing or split tax liability. In such cases, the home country can continue to argue that the true centre of life has not been moved.
In addition to personal tax liability, entrepreneurs face a second, often neglected question: do their activities abroad create a permanent establishment—and if so, where?
A permanent establishment in the tax sense does not require an office with a nameplate. A fixed place of business, a dependent agent, or even a regularly used home-office workstation abroad can be enough to raise the question of which state has the taxing right to which profits.
For location-independent business models such as digital services, consulting or remote work, this issue is particularly acute. An entrepreneur who registers a new residence in Portugal but spends most of their working time in their former home state may unintentionally create a permanent establishment there. The applicable DTA then determines which share of profit is allocated to which country.
If you want a clean tax separation, you must consistently relocate operational management: make decisions in the new country, carry out the key activities there and build the infrastructure there.
The social-security aspect of moving abroad is also often underestimated. Within the EU, Regulation (EC) No. 883/2004 generally applies, determining in which state social-security contributions are payable. One key factor is where the main focus of your work lies.
A self-employed entrepreneur who moves from one EU state but continues working in several EU states can end up with split social-security obligations, along with administrative effort and possible back payments. Those moving to a third country may lose entitlements from existing systems without an equivalent replacement.
Especially for high earners, careful review is worthwhile: in Switzerland, pension contributions are substantial and still mandatory. In Monaco, compulsory cover for the self-employed is organised far more straightforwardly.
An entrepreneur from the Netherlands with a 35% stake in his operating company decided to move to Dubai. The decision made commercial sense, but was not prepared from a tax-law perspective. Dutch exit taxation on his shares amounted to a seven-figure sum, due at the time of departure, with no deferral option for third countries. To make matters worse, he continued to actively manage his company and travelled to the Netherlands regularly, raising the issue of an ongoing permanent establishment. Had the move been planned 18 months earlier and accompanied structurally, key parts of the tax burden could have been reduced substantially through a corporate-law restructuring in advance.
In our day-to-day practice, we often see clients plan their departure emotionally as a liberating step, while treating the tax reality like a mere technicality. That is dangerous. We always say it very directly in the first meeting: the tax office is not a fan of farewells. When you leave, the treasury wants to treat it as if you sold your life’s work at that moment. If you do not proceed with clean documentation and, above all, sufficient lead time, you expose yourself to an estimation procedure that typically only goes one way: upwards.
Too little lead time. Exit planning is not a project for the last six weeks before the move. Corporate-law restructurings that reduce the tax burden on departure take time and must not give the impression of last-minute planning immediately before leaving.
Residence given up, but centre of life not relocated. Anyone who deregisters but in practice still works predominantly in the country of origin, has their family there and makes their key decisions there has not genuinely emigrated. Tax authorities across Europe are increasingly reviewing this consistently.
No substance built in the destination country. A mailbox-style arrangement in the destination state will not convince any tax authority. If you want to be tax-resident in Portugal, Monaco or Cyprus, you must actually live, work and decide there.
DTA rules misjudged. Not every double tax treaty works the same way. Some treaties allocate certain types of income to the source state regardless of residence. Anyone relying on general statements instead of checking the specific treaty text risks nasty surprises.
Social security overlooked. Especially intra-EU moves create complex overlaps that may only become apparent months or years later.
A move that is not prepared from a tax-law and corporate-law perspective can hardly be remedied afterwards. Reporting obligations that were missed, permanent establishments that arose unintentionally, and exit-tax burdens that could have been avoided with early planning: these are not abstract risks, but recurring patterns in advisory practice. A structured departure starts at least 12 to 24 months before the actual move, with a full inventory of all shareholdings, liabilities and tax connecting factors. Anyone who skips this step almost always pays the price later—and usually more expensively.
Leaving the country is one of the most far-reaching business decisions an entrepreneur can make. If you approach it in a structured way, you not only protect your assets but also lay the foundation for a durable international set-up. We can analyse your situation and guide you through the entire process, starting with a free initial consultation.
No. Formal deregistration is an indication, but not definitive proof. What matters is whether actual, substantive residence has been established in the new state and whether no material connecting factors remain in the country of origin.
No. Formal deregistration is an indication, but not conclusive evidence. The decisive factor is whether genuine, substantive residence has been established in the new state and whether no significant connecting factors remain in the country of origin.
Yes. In most EU states, the tax liability on hidden reserves arises even when moving within Europe. Within the EU and the EEA, however, there is often an interest-free deferral option as long as the shares are not disposed of.
This varies greatly depending on the country of origin. In Germany, for example, under § 6 AStG a participation of at least 1% at any point within the last twelve years is sufficient. Other European states sometimes set higher thresholds, but use comparable mechanisms.
