Relocating Internationally: The Three Things You Actually Need to Solve

International relocation advice typically focuses on the destination: which visa to apply for, which jurisdiction has the lowest tax rate, which country has the best quality of life. What this advice consistently fails to address is the practical infrastructure that must be in place from day one: tax residency, banking and healthcare. These three elements are interdependent, and failure in any one of them can make an otherwise well-planned relocation unworkable.

The Tax Residency Problem

Departure vs. Arrival

Tax residency is not a single event. It is two separate processes that must be coordinated:

1. Departure from the current tax jurisdiction: The individual must satisfy the departure rules of their home country. These vary enormously:

   • United Kingdom: The Statutory Residence Test (SRT) requires analysis of automatic overseas tests, automatic UK tests, and sufficient ties. Departure in mid-year may qualify for split-year treatment under Cases 1-4.
   • United States: US citizens and green card holders are taxed on worldwide income regardless of where they live. Departure requires renunciation of citizenship or relinquishment of the green card, with potential exit tax (Section 877A IRC).
   • Australia: The individual must cease to be a resident under the primary and secondary tests of Section 6(1) of the Income Tax Assessment Act 1936, typically requiring severance of ties and a clear intention not to return.
   • Germany: Section 1 EStG deems individuals resident if they maintain a dwelling (Wohnung) in Germany. Simply leaving does not end residency if a furnished property is retained.
   • France: Article 4B of the CGI defines residence by reference to home (foyer), principal place of abode, professional activity, or centre of economic interests. Any one is sufficient.

2. Arrival in the new jurisdiction: The individual must positively establish tax residency in the destination country. This requires satisfying the destination country's residency tests, which typically include 183-day presence, habitual abode, centre of vital interests, or registration with the tax authority.

The Gap Problem

The most dangerous scenario is the gap: the period between departure from one jurisdiction and establishment of tax residency in another. During this gap:

• The individual may be tax resident nowhere, which creates problems with financial institutions (who require a tax residency certificate for CRS purposes), insurance providers, and investment platforms.
• Alternatively, the individual may inadvertently remain tax resident in their former jurisdiction because the departure conditions were not properly satisfied.
• Worst case: the individual is tax resident in both jurisdictions simultaneously, potentially facing double taxation with no treaty relief if the tie-breaker provisions are not properly engaged.

How to Solve It

• Map the departure rules of the home jurisdiction with precision. Identify the exact conditions required and the date on which they will be satisfied.
• Map the arrival rules of the destination jurisdiction. Identify when tax residency will be established and what documentation is required (registration, physical presence, substance).
• Ensure there is no gap. The departure date from one jurisdiction and the arrival date in the other should be coordinated to avoid a period of statelessness.
• Obtain a Tax Residency Certificate (TRC) from the destination jurisdiction as soon as eligibility permits. This document is required by banks, brokerages and other financial institutions under CRS.

The Banking Problem

Why Banking Breaks

Banking is the most frequent point of failure in international relocations. The problems include:

1. Home-Country Bank Account Closure

Many banks will close accounts when notified that the account holder has become non-resident. This is particularly common with:

• UK high street banks (Barclays, Lloyds, NatWest) for customers who move to non-approved jurisdictions
• US banks for customers who move abroad and fail to update their address (triggering FATCA compliance issues)
• EU banks when the customer's new jurisdiction is outside the EU/EEA

2. Destination-Country Account Opening

Opening a bank account in the new jurisdiction often requires:

• A valid local residence visa or permit (chicken-and-egg problem: the visa may require a bank account, and the bank account may require a visa)
• Proof of local address (utility bill, rental agreement)
• Source of wealth documentation that meets the local bank's AML/KYC standards
• Physical presence at the bank branch (many jurisdictions do not permit remote account opening for new residents)

3. The CRS Mismatch

Under the Common Reporting Standard, financial institutions report account holder information to the tax authority of the jurisdiction where the account holder is tax resident. If the individual's CRS self-certification does not match their visa status, address, or other documentation, the bank may:

• Refuse to open the account
• Request additional documentation
• Report to multiple jurisdictions simultaneously
• Close the account if inconsistencies are not resolved

How to Solve It

• Do not close home-country accounts prematurely. Maintain at least one account in the former jurisdiction until the destination-country banking relationship is fully established and tested (3-6 months of smooth operation).
• Open destination-country accounts early. If possible, open accounts during a preliminary visit or through a private banking relationship. Some banks permit account opening for visa applicants before the visa is finalised.
• Prepare source of wealth documentation in advance. This includes: tax returns from the preceding 3-5 years, business financial statements, property sale contracts, inheritance documentation, and any other evidence of how the individual's wealth was accumulated.
• Consider international or multi-currency banking. Banks like HSBC Expat (Jersey), Standard Chartered (Singapore/UAE), and Swissquote offer multi-jurisdictional capabilities that reduce dependence on a single country's banking system.

The Healthcare Problem

Why Healthcare Is Overlooked

Advisers focused on tax and immigration rarely address healthcare. The result: clients arrive in their new jurisdiction and discover that:

• They are not eligible for the public healthcare system (either because their visa type does not qualify or because there is a waiting period)
• Their home-country private health insurance does not provide coverage in the new jurisdiction
• They have pre-existing conditions that are excluded from new insurance policies
• The local healthcare standard does not meet their expectations, particularly in developing countries popular with tax-motivated migrants (UAE, Panama, Georgia, Thailand)

Coverage Models by Jurisdiction

Jurisdictions with universal healthcare for residents:

• UK (NHS — available to all residents, including visa holders)
• Portugal, Spain, France, Italy, Germany (public systems, but access may require social security registration and contributions)
• Singapore (subsidised public healthcare, but private insurance is standard for expatriates)
• Thailand (public system available, but private insurance strongly recommended)

Jurisdictions requiring private insurance:

• UAE (health insurance is mandatory; employers must provide it for employed individuals, self-employed must arrange their own)
• Panama (no universal coverage; private insurance essential)
• Cayman Islands, Bermuda (private insurance mandatory)
• Georgia (affordable private insurance available; public system is basic)

Jurisdictions with limited coverage for new arrivals:

• Australia (Medicare is available to citizens and permanent residents; temporary visa holders require private insurance)
• New Zealand (public healthcare available to residents, but waiting periods may apply for certain treatments)
• Cyprus (GESY universal system, but registration and contributions required)

Critical Considerations

• Pre-existing conditions: Most international health insurers apply exclusions or surcharges for pre-existing conditions. Securing coverage before relocating is essential.
• Continuity of care: If the individual is under treatment for a chronic condition, arrangements must be made to continue treatment in the new jurisdiction. Medical records, prescriptions and specialist referrals should be prepared before departure.
• Dental and optical: Often excluded from standard health insurance plans. Separate coverage or out-of-pocket budgeting is required.
• Emergency evacuation: For relocations to developing countries or remote locations, evacuation insurance should be considered.

How to Solve It

• Secure international health insurance before relocating. Leading providers include Cigna Global, Bupa International, AXA International, and Allianz Care. Premiums range from USD 3,000-15,000 per year per person depending on age, coverage level and region.
• Register with the destination country's public healthcare system as soon as eligibility permits.
• Identify local hospitals, GPs and specialists before arrival. For families with children, locate paediatric facilities and establish relationships early.
• Maintain home-country health insurance for a transitional period (3-6 months) to cover any treatment that was in progress at the time of departure.

The Integration Framework

The three elements — tax residency, banking and healthcare — must work together. A practical timeline:

Months -6 to -3 (Pre-departure):

• Engage tax advisers in both the departure and arrival jurisdictions
• Begin source of wealth documentation
• Research and apply for international health insurance
• Open preliminary banking relationship in the destination country (if possible)

Month 0 (Departure):

• Ensure departure conditions are documented (e.g., UK SRT day count begins, property is let or sold, employment is terminated)
• Activate international health insurance
• Maintain home-country banking temporarily

Months +1 to +3 (Arrival):

• Register with the destination country's tax authority
• Complete local banking KYC process
• Register with the local healthcare system
• Obtain Tax Residency Certificate as soon as eligible

Months +3 to +6 (Stabilisation):

• Confirm CRS reporting is correctly aligned with new tax residency
• Transition home-country accounts to non-resident status or close
• Establish local medical relationships
• Review insurance coverage for adequacy

Key Takeaways

• Successful international relocation requires solving three problems simultaneously: tax residency, banking and healthcare. Failure in any one creates cascading problems in the others.
• Tax residency is a two-sided problem: departure from the home jurisdiction must be properly executed, and arrival in the new jurisdiction must be positively established. A gap between the two creates compliance and practical risks.
• Banking is the most frequent failure point. Accounts may be closed by the home-country bank upon notification of non-residence, and opening accounts in the new jurisdiction requires documentation that many relocators do not have ready.
• Healthcare coverage gaps are dangerous and common. International health insurance should be arranged before departure, and pre-existing conditions must be disclosed and covered.
• The entire process should be planned 3-6 months in advance, with professional advisers engaged in both the departure and arrival jurisdictions. Reactive planning after arrival is significantly more expensive and less effective.
• The interaction between CRS reporting, bank KYC requirements, and tax residency certificates means that consistency across all three elements is critical. Discrepancies will trigger queries from financial institutions, tax authorities, or both.
