Frequently Asked Questions

What is the difference between tax residency and domicile?

Tax residency generally refers to where an individual lives and is subject to tax on their worldwide income, determined by physical presence tests. Domicile is a more permanent concept, often linked to an individual's 'home country' or 'country of origin' with which they have the closest ties, and it often dictates inheritance or estate tax obligations, even if one is not a tax resident.

What are 'exit taxes' and how do they apply?

Exit taxes, or expatriation taxes, are levied by some countries when an individual gives up their tax residency. These taxes often treat assets as if they were sold on the date of departure, resulting in a deemed capital gain tax liability on unrealized gains, even if the assets are not actually sold.

How does a new primary residence affect my global income tax?

Establishing a new primary residence typically shifts your primary global income tax liability to that new country. While some source-country taxation may persist, the new jurisdiction will likely tax your worldwide income, subject to tax treaties designed to prevent double taxation.

Are there wealth taxes I need to consider when relocating?

Yes, some countries impose annual wealth taxes on net assets, or specific property taxes. When relocating, you must understand if your new primary residence jurisdiction has such taxes and how they would apply to your global asset portfolio. Careful planning can sometimes mitigate these.

How do inheritance and gift taxes change with a new residence?

Inheritance and gift taxes are highly dependent on both your domicile and the location of your assets. A change in primary residence can significantly alter which country's estate and gift tax laws apply to your worldwide wealth, potentially necessitating a review of your estate plan.

What role do double taxation treaties play?

Double taxation treaties (DTTs) are bilateral agreements between countries designed to prevent individuals from being taxed twice on the same income or assets. They establish rules for allocating taxing rights, define residency, and often provide mechanisms for relief from double taxation.

Should I consider a trust or foundation when relocating my primary residence?

Yes, trusts and foundations are powerful tools for wealth structuring and can be critical for optimizing tax efficiency and protecting assets when establishing a new primary residence. Their structure and situs should be carefully reviewed to align with the tax laws of the new jurisdiction and your overall objectives.

What are common pitfalls to avoid during this process?

Common pitfalls include failing to fully sever tax ties with the former country, misunderstanding the new country's residency rules, inadequate asset restructuring, overlooking reporting requirements, and underestimating the importance of specialized legal and tax advice across all relevant jurisdictions.
