Compliance Obligations After Acquiring New Citizenship or Residency

Acquiring a second citizenship or a new residency status is often the point at which an individual's attention turns to enjoying the benefits of their new status. It is also the point at which a new set of compliance obligations is triggered — obligations that are frequently misunderstood, underestimated, or simply overlooked.

This guide maps the key reporting and compliance obligations that arise for HNW individuals following the acquisition of a new citizenship or residency status.

Common Reporting Standard (CRS): What Financial Institutions Will Report

The Common Reporting Standard (CRS), developed by the OECD and implemented by over 100 participating jurisdictions, requires financial institutions to identify the tax residency of their account holders and report account information to the tax authority of each jurisdiction of tax residence.

How CRS interacts with new citizenship or residency:

When you acquire a new residency status — particularly one that triggers tax residency in the new country — your financial institutions in existing jurisdictions will typically ask you to update your CRS self-certification. You are required to disclose:

• Your jurisdiction(s) of tax residency
• Your Tax Identification Number (TIN) in each jurisdiction

Financial institutions that hold accounts for you will report your account balances, income, and other information to the tax authority of each declared jurisdiction of tax residency.

What this means practically:

• A UK bank holding accounts for a new UAE resident (who has acquired UAE Golden Visa status) will, if it collects UAE tax residency information, report account details to HMRC (UK, if still tax resident there) — not to the UAE (which does not participate as a recipient of CRS data in the same way, given the UAE's tax position)
• A Swiss bank holding accounts for someone who has acquired Maltese citizenship and established Malta tax residency will report to the Maltese tax authority
• If you have not updated your CRS status with financial institutions and continue to be treated as a resident of your previous jurisdiction, incorrect reporting may occur — both under-reporting and over-reporting

You have a legal obligation to update your CRS self-certification when your circumstances change. Providing a false self-certification is an offence under the domestic law of most CRS-participating jurisdictions.

FBAR: Annual Filing for US Persons

FinCEN Report 114 (FBAR) must be filed annually by any US person who has a financial interest in, or signature authority over, foreign financial accounts if the aggregate value exceeds $10,000 at any point during the calendar year.

FBAR is relevant to investment migration in the following contexts:

1. Acquiring new accounts in a new jurisdiction — bank accounts opened to facilitate a Golden Visa investment, residency programme, or citizenship application create new foreign account obligations for US persons

2. Acquiring interests in foreign entities — investing through a foreign company (as many Golden Visa programmes require) may create FBAR obligations if the US person has a financial interest in the entity's foreign accounts

3. New residency triggering new accounts — relocating to a new country typically means opening new local bank accounts, which are immediately within scope

FBAR penalties are severe: for non-wilful violations, a penalty of approximately $10,000 (inflation-adjusted) applies per report (per year), not per account — the position confirmed by the US Supreme Court in Bittner v United States (2023); for wilful violations, the greater of approximately $100,000 (inflation-adjusted) or 50% of the account value per violation. Criminal penalties apply in egregious cases.

FBAR is filed electronically with FinCEN by 15 April each year (automatic extension to 15 October available).

IRS Form 8840: Closer Connection Exception for US Tax Residency

US individuals who spend significant time in the United States but are not US citizens or green card holders may become US tax residents under the Substantial Presence Test — spending 183 days or more in the US in the current year, or a weighted sum over three years.

IRS Form 8840 allows a non-citizen, non-green-card holder to claim the Closer Connection Exception — avoiding US tax residency under the Substantial Presence Test by demonstrating that they have a closer connection to a foreign country.

For investment migrants who frequently visit the US (to maintain US business relationships, visit family, or oversee US investments), the Substantial Presence Test is a genuine risk. Form 8840:

• Must be filed each year that the exception is claimed
• Requires you to demonstrate that you maintained a tax home in a foreign country throughout the year
• Requires that you had a closer connection to that foreign country than to the US
• Cannot be used by those who held a green card at any point during the year
• Cannot be used to avoid US tax if you spent 183 days or more in the US in the current year (only the weighted 3-year test version applies)

For investment migrants from countries like the Caribbean (whose programmes require little time in the country), the Form 8840 exception is particularly important if US time is substantial.

UK Inheritance Tax: The Domicile Tail

Acquiring a new residency or citizenship does not automatically end UK Inheritance Tax (IHT) exposure for former UK residents.

From 6 April 2025, the UK abolished the concept of domicile (and the old "deemed domiciled after 15 of the previous 20 years" rule) for tax purposes and moved IHT onto a residence-based footing. Under the new framework, an individual is a "long-term UK resident" — and so within the scope of UK IHT on their worldwide estate — once they have been UK tax resident for at least 10 of the previous 20 tax years.

The fundamental risk for former UK residents remains: once you have become a long-term UK resident, leaving the UK does not immediately remove your worldwide estate from UK IHT. A "tail" applies — broadly between three and ten years depending on how long you were UK resident — during which your worldwide estate stays within the UK IHT net after you cease to be UK resident.

Practical implication for investment migrants:

A UK-based HNW individual who acquires Caribbean citizenship and relocates to the UAE, intending to exit UK tax residency entirely, cannot immediately assume their worldwide estate is outside the UK IHT net. Depending on the length of prior UK residence, the UK IHT tail can extend many years into the future.

During this tail period, assets held in offshore trusts (which were previously outside UK IHT under the pre-2025 excluded property trust rules) may also be brought into scope under the new framework. Immediate planning — reviewed against the post-2025 rules — is essential.

Obligation to Disclose New Passports to Existing Country

Many countries require their citizens to notify relevant authorities upon acquiring a foreign passport or citizenship:

India: Upon acquiring another citizenship, a person automatically ceases to be an Indian citizen and must surrender their Indian passport to an Indian consulate or mission. Failure to surrender an Indian passport after acquiring another citizenship is an offence.

China: A Chinese national who acquires foreign citizenship is expected to surrender their Chinese passport. China does not recognise the dual citizenship, and using a Chinese passport after naturalisation elsewhere is problematic.

South Africa: South Africa requires dual nationals to enter and exit South Africa on their South African passport (not a foreign one), and citizens who acquire another nationality in some circumstances may need to apply to retain South African citizenship.

UK: The UK does not require disclosure of additional citizenships to any government authority in normal circumstances. However, security-cleared employees and certain public servants may have contractual or security obligations.

US: A US person who acquires a foreign nationality (without the intent to relinquish US citizenship) retains US citizenship and has no obligation to notify the State Department of the additional citizenship in most cases. However, US citizens should travel to and from the US on their US passport, and using a foreign passport to enter the US can create complications.

Passport Application Conflict Disclosure

When applying for a new passport — whether upon initial citizenship or renewal — most countries require disclosure of all other citizenships and passports currently held. Failure to disclose can constitute fraud in the passport application and create grounds for passport cancellation or criminal prosecution.

For investment migrants who have used different names, name spellings, or have changed personal details across different jurisdictions, consistency in documentation is important. Conflicts between name spellings, dates of birth, or other identifying information across multiple passports and supporting documents require careful management.
