Two-Stage Tax Residency Relocation: When It Holds and When It Is a Risk.
Moving first to a treaty country and then to the final destination is a widely circulated technique in tax mobility forums and blogs. It is also a figure catalogued in the literature on improper use of treaties, and since the multilateral instrument came into force administrations have a specific tool to deny its benefits. This guide explains when such a structure holds, when it does not, and what separates it from a legitimate relocation.
The recipe that circulates, and what it leaves out
Tax mobility forums and blogs repeat a recommendation in almost identical wording: before moving to a low-tax jurisdiction, first reside in a "bridge country" that is not flagged, preferably one with a double taxation treaty and information exchange, obtain your tax residency certificate there, and relocate afterwards.
The recommendation rests on real logic, and in certain circumstances it describes a perfectly valid arrangement. What is almost never mentioned is that the structure has a technical name, is catalogued in the literature on improper use of treaties, and since 2018 administrations have had a tool designed specifically to disarm it.
This guide explains when a two-stage relocation holds and when it does not.
Why the technique exists
The underlying reasoning is sound. Where the country of origin and the final destination have no treaty, three things follow:
- There is no tie-breaker. If both States treat you as resident, no rule decides which prevails.
- There is no double taxation credit.
- The destination's certificate obliges the origin to nothing.
If a third jurisdiction does hold a treaty with the country of origin, moving there first supplies what was missing: the Article 4 ladder, and often a clause requiring credit for exit tax. None of that is fictitious.
What this is actually called
In international tax literature, using an intermediate jurisdiction to access treaty benefits that would not be available directly is called treaty shopping, and its variants are described and classified: direct conduits, stepping-stone structures, triangular arrangements, hybrid entities and — the one at issue here — taxpayer emigration to another treaty State.
A figure being catalogued does not make it unlawful. It makes it known. And known structures attract the scrutiny that known structures attract.
The tool that changed the picture
The OECD's BEPS project introduced, through the multilateral instrument, a general anti-abuse clause now extended across most treaties in force: the principal purpose test.
Its wording is deliberately broad: treaty benefits may be denied where it is reasonable to conclude that obtaining that benefit was one of the principal purposes of the arrangement or transaction, unless it is established that granting it accords with the object and purpose of the relevant provisions.
Note the formulation. It does not require the tax purpose to have been the only one, or even the main one: it is enough that it was one of the principal ones. That is a low threshold, and it shifts the burden of argument onto the taxpayer.
What separates a valid relocation from a fragile structure
The difference is not the number of stages. It is whether each stage corresponds to a real residence.
Supports the relocation:
- An independent reason for the intermediate stage, unrelated to the tax benefit: business in the region, family, work, a project, pre-existing ties.
- Actual substance: a real home, presence, a centre of vital interests genuinely relocated.
- Tax compliance in the intermediate jurisdiction: registration where required, returns filed, obligations met.
- Coherent duration. There is no statutory period, but a residence sustained over years defends itself; a brief stay followed by an immediate jump does not.
- Contemporaneous documentation of the reason. This is the most neglected point: business reasons are evidenced by correspondence, decisions and facts from the time, not by explanations written years later.
Weakens the relocation:
- Nominal residence without effective presence.
- An intermediate stage that coincides in time — and only in time — with a significant asset event.
- The absence of any reason other than the tax one.
- A documentary trail showing the structure was designed to capture the treaty.
What a two-stage relocation does not resolve
The origin country's exit tax. These regimes generally count the period of liability to the origin State, not treaty residence elsewhere, so an intermediate stop does not reset the clock. There is a ruling to that effect in at least one European jurisdiction. And the intermediate move may trigger the charge in its own right.
Outstanding obligations in the intermediate jurisdiction. Being tax resident somewhere means its obligations, not only its treaties. Invoking years of intermediate residence may open questions about the returns for those years.
The need for advice in each jurisdiction. A relocation involving three countries requires advisers in three countries. No firm answers for foreign law.
On vocabulary
A practical observation that is not cosmetic. Terms such as "triangulation", "bridge country" or "structure" belong to the register of schemes, and they frame an arrangement before anyone examines its substance.
Where a relocation rests on real reasons — and many do — the correct description is the one reflecting those reasons: a person whose activity sits in a region moves their residence there, in stages, for operational or family reasons. This is not window-dressing: the principal purpose test asks precisely about purpose, and a real purpose, where it exists, must be capable of being evidenced from the outset.
The myths that cost the most
"If there's a treaty, the benefits are automatic." Since the multilateral instrument came into force, no. The principal purpose test applies on top of the treaty.
"Everyone does it, so it's safe." A technique being widespread is exactly what makes administrations familiar with it.
"A year in the intermediate country is enough." There is no statutory period, but there is no shortcut either: what is examined is the reality of the residence, and one year followed by an immediate jump is weak.
"Nobody is going to reconstruct my history." Automatic exchange of information allows precisely that.
What to do
- First check whether a treaty exists between your country of origin and the final destination. If it does, you probably need no intermediate stage at all.
- If you opt for two stages, make sure the intermediate one has its own reason and document it from the outset.
- Treat the intermediate residence as a real one, tax obligations included.
- Do not count on it solving the exit tax. It does not.
- Coordinate advice across all three jurisdictions, and be wary of anyone offering to resolve it all from one.
Questions from the source
Questions, answers, and sources preserved from the historical archive. Nucleus has not verified their currency or links.
What is a 'bridge country'?
It is the informal name for an intermediate jurisdiction to which someone moves their tax residency before relocating to their final destination, usually because that intermediate jurisdiction does hold a double taxation treaty with the country of origin while the final destination does not. The technique seeks a tie-breaker rule and a credit mechanism that would not exist on a direct move.
Is it legal to relocate in two stages?
Moving your tax residency is a right, and doing so in two stages is not unlawful in itself. What determines the outcome is whether each stage corresponds to a real residence. An effective, sustained intermediate residence with its own reason is a valid legal position; a nominal residence set up to capture treaty benefits is precisely what anti-abuse clauses target.
What is the principal purpose test?
It is a general anti-abuse clause incorporated into most treaties through the multilateral instrument arising from the BEPS project. It allows treaty benefits to be denied where it is reasonable to conclude that obtaining that benefit was one of the principal purposes of the arrangement or transaction, unless it is established that granting it would accord with the object and purpose of the relevant provisions.
Does an intermediate stop avoid the origin country's exit tax?
It should not be relied upon. Exit taxation regimes generally count the period of liability to the origin State, regardless of where treaty residence sat, so an intermediate stage does not reset the clock. There is a ruling to that effect in at least one European jurisdiction. In addition, the intermediate change of residence may itself trigger the charge.
How long should the intermediate stage last?
There is no statutory period. What is examined is not duration but the reality of the residence: an actual home, a centre of vital interests, compliance with tax obligations, presence. A brief stay followed by an immediate jump to the final destination is hard to defend; a residence sustained over several years, with substance and its own reason, is a different matter.
