The sequencing error
People building cross-border tax structures almost always start with the wrong question. They ask: "Where should I incorporate my holding company?" They should ask: "Where should I be tax-resident as an individual?"
The personal tax residency position is the foundation. It determines which country has primary taxing rights over your worldwide income, which tax treaties apply, and which controlled-foreign-corporation rules can reach your holding structures. A sophisticated holding arrangement sitting on an unaddressed personal residency problem will either fail outright or produce expensive litigation when challenged.
Layer 1: Tax Residency
Tax residency is the legal determination of which country has the right to tax your income. It is established primarily by:
- Physical presence: Most countries use a 183-day test. Some countries use shorter tests or no defined threshold.
- Centre of vital interests: OECD model treaty tiebreaker — where is your family, your permanent home, your primary economic relationships?
- Formal registration: Many jurisdictions require you to formally register as a resident or deregister from your prior country — it's not just about where you sleep.
Exit taxes and deemed disposals
Many countries impose exit taxes when you cease residency — a deemed disposal of assets at market value on the day you leave, triggering a capital gains liability. UK, Australia, Canada and several European countries have exit tax regimes. Model this before you plan the move, not after.

Layer 2: Domicile
Domicile is a separate legal concept from residency, primarily relevant in UK common-law jurisdictions. Your domicile of origin is acquired at birth and persists until replaced. Your domicile of choice is acquired by residing in a country with the fixed and settled intention of remaining there permanently.
In the UK, domicile determines exposure to UK inheritance tax on worldwide assets. A UK-resident non-domiciliary historically benefited from the remittance basis of taxation. This regime has been significantly reformed from April 2025 — seek current professional advice.
Changing domicile is harder than changing residency. It requires evidence of settled intention: property ownership abroad, disposal of UK home, family ties abroad, stated intention in a will, extended physical absence. Courts look at the totality of circumstances.
Layer 3: Holding Structure
Once personal residency and domicile are established, the holding structure can be constructed above them.
Controlled foreign corporation (CFC) rules
CFC rules are the mechanism by which home-country tax authorities "pierce" foreign holding structures and attribute income back to a resident individual. Almost every sophisticated tax jurisdiction has them. The basic test: if you control a foreign entity and that entity earns passive income not taxed at an acceptable rate, the income may be attributed to you and taxed in your hands.
CFC rules make it largely ineffective to hold a Cayman or BVI company generating investment income while remaining tax-resident in the UK, Australia, or Germany. The income comes back to you under CFC attribution regardless of what the offshore structure says.
When structures do work
Holding structures work when they reflect genuine commercial substance in the jurisdiction where the structure sits, AND the beneficial owner's personal tax residency is in a country that either has no CFC rules, or where the holding jurisdiction's tax rate exceeds the CFC threshold, or where the income type is exempt.
A UAE-resident founder holding a UAE free zone company that earns consulting income — and who genuinely lives in Dubai — has a structure that works. The same structure for a UK-resident founder who visits Dubai four times a year is almost certainly attributed back to UK residence and subject to UK tax.
The sequencing summary
Step 1: Identify the target personal tax residency and model the exit. Step 2: Address domicile if you're in a common-law jurisdiction with inheritance tax exposure. Step 3: Build the holding structure above the settled residency foundation. Step 4: Ensure substance in every entity in the chain. Step 5: Maintain annual compliance in all relevant jurisdictions.
