The first 90 days after an international relocation determine whether the move actually works. Applicants who sequence the early tasks correctly build momentum and avoid the cascading delays that frustrate many wealth-migration relocations. Applicants who treat the first 90 days as "settling in" and leave the administrative work for later often discover that specific deadlines have been missed, bank accounts cannot be opened, schools have been allocated elsewhere, and the entire relocation has to be rescued through specialist intervention. Here is the week-by-week checklist that works.
Most wealth-migration relocations require multiple trips between the exit and destination jurisdictions during the first 90 days — collecting documents, visiting banks, meeting tax counsel, addressing family issues. Private charter flexibility handles the scheduling problem that commercial aviation cannot.

Collect residency documents. Most residency applications submitted before arrival require personal collection of the final documents at a specific government office within a specific window after arrival. Portugal requires SEF collection visits. Italy requires Questura appointments. Malta requires Identity Malta collection. Switzerland requires cantonal migration office visits. UAE requires Emirates ID biometric completion at approved centres. The specific collection point and timeline vary by jurisdiction but the principle is universal — the residency card or permit is not active until it has been physically collected, and many other processes (banking, schooling, property registration) require the active residency document as evidence.
Register at the local municipality. Many European destinations require residents to register at the local municipality or commune within the first seven to thirty days of arrival. The registration certificate (certificate of residence, certificado de residencia, Wohnsitzbestätigung, and similar local equivalents) is typically a prerequisite for opening local bank accounts, enrolling in healthcare systems, registering children in schools, and accessing other local services. The specific registration deadline varies by jurisdiction — Italy requires 90 days for EU citizens, Switzerland requires 14 days for all residents, Portugal requires 90 days for EU citizens and immediate registration for non-EU visa holders. Missing the deadline can trigger fines and administrative complications.
Activate local mobile phone service. Tourist roaming or international SIM services do not work for most local services that require phone number verification. Activate a local mobile account (not just a prepaid tourist SIM) with a contract in the resident's name, using the new residency documents as identification. This enables receipt of SMS verification codes from local banks, government services, schools, and utilities — which is the specific friction point that blocks many first-month activities for applicants who arrive with only international phone coverage.
Banking is typically the slowest element of the first 90 days, which is why it should start as early as possible — ideally in week two, as soon as the residency documents are collected and municipal registration is complete. Banking delays cascade into delays with property registration, utility contracts, schooling payments, and almost everything else that requires a local bank account.
Open local bank account(s). The specific bank choice matters. International banks with dedicated expat services (HSBC, UBS, Credit Suisse, Deutsche Bank, BNP Paribas, Emirates NBD for UAE) typically handle new-resident applications more efficiently than purely local banks. Required documentation typically includes: residency permit or card, municipal registration certificate, proof of local address (rental lease or property deed), tax identification number from the destination jurisdiction (or evidence that it is being applied for), source of funds documentation showing the origin of wealth being brought into the new jurisdiction, and in some cases personal references or introductory letters from existing banking relationships. Applicants should budget two to six weeks for the full account opening process, and should expect some iteration as the bank's compliance team requests additional documentation.
Apply for destination tax identification number. Each jurisdiction has its own tax ID system: Portugal issues a NIF (Número de Identificação Fiscal), Italy issues a Codice Fiscale, Spain issues a NIE/NIF, UAE issues a Tax Registration Number through the Federal Tax Authority. The tax ID is typically required for banking, property transactions, employment, and most significant financial interactions, and should be obtained within the first two weeks of arrival. Some jurisdictions issue tax IDs within days of application; others take weeks. The application process is typically straightforward but requires appearing at the relevant tax office with residency documentation and proof of address.
Coordinate with destination tax counsel. If specialist destination tax counsel has been engaged (typically a requirement for flat-tax elections, non-dom regime applications, or complex planning), the first month is when the formal tax residency establishment work needs to happen. This includes filing the flat-tax election (Italy), the non-dom registration (Malta, Cyprus), or the equivalent local procedure. Missing the specific deadlines for these elections can defer the tax benefits by a full tax year and can create compliance complications that take specialist intervention to resolve.
Finalise schooling enrolment. If the schooling search and application was done correctly during the 9-18 month pre-arrival planning period (see the separate family relocation article in this pillar), the first month should involve finalising the school enrolment paperwork, paying the initial fees, and managing the logistics of the first school day. For families whose children will start school during the first 90 days, the specific enrolment completion and first-day preparation are priority items for weeks 4-6. For families whose children will start at the beginning of the next academic year, the first month should confirm the acceptance and pay the enrolment deposit to secure the place.
Enrol in destination healthcare system. Most European destinations require residents to enrol in either the public healthcare system (Portugal SNS, Italy SSN, Spain SNS, Switzerland KVG/LAMal mandatory private insurance) or to maintain adequate private international insurance that meets the residency requirements. The enrolment process varies by jurisdiction but typically requires: residency documentation, tax ID, proof of local address, and in some cases income evidence or specific insurance premium payments. Switzerland specifically requires all residents to enrol in mandatory private health insurance (KVG/LAMal) within three months of arrival, and failure to enrol can result in the cantonal authority automatically assigning the resident to a default insurance plan at potentially unfavourable terms.
Transition international health coverage. For applicants who were using international health insurance during the residency application period, the first 90 days is when the coverage should transition from the international plan to the destination's local system. This transition should be managed carefully to avoid gaps in coverage — the international plan should remain active until the local enrolment is confirmed and the local coverage is effective, and only then should the international plan be reduced or cancelled.
Most destinations require proof of health insurance during the first 90 days while the local healthcare enrolment is being processed. SafetyWing's global policy provides continuous coverage during the transition period and covers multi-country transitions when relocations involve extended exit phases.
Get a Quote →Set up utility accounts. Electricity, gas, water, internet, and landline phone services typically need to be transferred from the previous occupant or set up in the new resident's name within the first two months of arrival. Each jurisdiction has specific utility providers and specific contract requirements, and applicants frequently need to provide: residency documentation, tax ID, proof of address, and initial deposits. Internet service typically requires the longest setup time in most destinations (two to six weeks from contract signing to active service), so it should be initiated early in the process if fast internet access is a priority.
Vehicle registration and driving licence. If the relocation involves bringing a vehicle from the exit jurisdiction, the destination typically requires formal import and re-registration within a specific window (often three to twelve months depending on the jurisdiction). Driving licences also require specific conversion processes. Within the EU, exchange of EU driving licences is typically straightforward. For non-EU licences, most European destinations require either an international driving permit (valid for limited period) or conversion to a local licence, which may require a driving test in some cases. Switzerland and Italy have specific rules about driving licence conversion that should be researched ahead of the move. UAE requires Emirates ID before the driving licence can be issued.
Property formalisation. If the relocation involves property purchase in the destination rather than rental, the formal property registration, tax payments (property transfer taxes, registration fees, notary fees), and ongoing property management arrangements should be finalised in the second month of residence. Property purchases typically involve notary appointments, tax authority submissions, and registration filings that take several weeks to complete. Property rentals are usually faster but still require formal registration with the local municipality and sometimes with the tax authority.
The final weeks of the first 90 days should focus on formally closing tax residency and administrative obligations in the exit jurisdiction. This element is often overlooked because applicants assume that establishing residence in the new jurisdiction automatically terminates residence in the previous one — but most jurisdictions require specific notification and documentation to confirm the transition.
Notify exit-jurisdiction tax authority. UK departures should submit Form P85 or equivalent Self Assessment declarations confirming that UK tax residence has ended under the Statutory Residence Test. US persons should be aware that US citizens remain subject to US worldwide taxation regardless of residence; only US residents who are not citizens can terminate US tax residency through specific procedures (typically involving Form 8854 for long-term residents). Most European countries require a formal change-of-residence notification to the local tax authority with the effective date aligned to when the individual actually ceased being tax resident under local rules.
Close or convert exit-jurisdiction accounts. Bank accounts, investment accounts, utility accounts, insurance policies, and other administrative relationships in the exit jurisdiction should be either closed, transferred, or converted to non-resident status. Some relationships (pension accounts, specific investment accounts, estate planning structures) should typically be maintained with modified terms rather than closed, and specialist advice from exit-jurisdiction counsel is essential to manage the specific transitions correctly.
Update exit-jurisdiction official records. Government records including driving licence, voter registration, property ownership, and similar administrative records should be updated to reflect the new residence. Some records (voter registration specifically) may require specific notifications or de-registration to comply with the new jurisdiction's rules about voting rights and political participation.
Complete the cross-border tax coordination. The final weeks of the first 90 days should include a coordination meeting between exit-jurisdiction and destination-jurisdiction tax counsel to confirm that the transition is complete, that tax residency has cleanly moved between jurisdictions, that there are no gaps or overlaps in tax obligations, and that any specific transition elements (the UK Temporary Repatriation Facility, Italian flat tax election, non-dom registration) have been properly filed and acknowledged by the relevant authorities.
Three specific mistakes cause the most problems in the first 90 days.
Delaying tax registration in the new jurisdiction. Most destinations expect new residents to register with the local tax authority within a specific window (often 30 to 90 days of arrival) to establish the transition from previous tax residency. Delays can create gaps or overlaps in tax residency status that cause compliance problems later, including potential dual residency with associated tax complications, missed deadlines for flat-tax elections or non-dom regime applications, and complications in resolving the transition of historical investment and employment income from the exit jurisdiction.
Over-committing to the new jurisdiction before residency is fully confirmed. Buying property, signing long-term leases, or cutting ties to the previous jurisdiction before the destination residency is formally granted can leave applicants in an uncomfortable position if the residency application encounters delays or complications. The practical rule is to maintain flexibility on high-value commitments until the residency documentation is in hand and the tax residency has been formally established. Initial property rental rather than immediate purchase, short-term leases rather than long-term commitments, and maintained exit-jurisdiction ties during the first 90 days all support flexibility that can be valuable if complications arise.
Underestimating the family adjustment timeline. Children and spouses frequently need longer than the main applicant to adjust to the new destination. Relocations where the main applicant prioritises tax and business setup over family integration often produce dissatisfaction in the first year that can derail the entire relocation. The first 90 days should include specific attention to family adjustment — social activities for the spouse, school adjustment for children, and cultural integration activities that help the family feel genuinely at home in the new destination rather than just technically resident there. The long-term success of the relocation frequently depends more on this family adjustment than on the technical tax and administrative setup.
Beyond the specific 90-day checklist, several ongoing considerations should be managed through the first year of new residency. Tax filing in both jurisdictions covering the year of transition, which typically requires coordinated advice from exit and destination tax counsel. Property and investment portfolio review to ensure alignment with the new jurisdiction's tax framework and to take advantage of any specific regime benefits. Cultural and language integration for the family, which supports long-term sustainability of the relocation. Social network development in the new destination, which often lags the administrative setup by several months but is typically what determines whether the relocation feels like a success at the one-year mark.
The first 90 days establishes the administrative foundation. The first year establishes whether the foundation actually supports a sustainable long-term residence. Applicants who complete the 90-day checklist but neglect the longer-term integration often find themselves administratively settled but emotionally unsettled, and some reverse the relocation within two to three years. Applicants who approach the first year as a genuine settling-in period — social, cultural, and family integration alongside the administrative setup — typically produce more durable outcomes and report higher satisfaction with the relocation decision.
The first week should prioritise three essential actions that unlock everything else. First, collect any residency documentation that was prepared during the application phase, including biometric cards, residency permits, and identification documents — most jurisdictions require personal collection of these documents from specific government offices within a specific window after arrival, and delays here can cascade into delays with banking, schooling, and property registration. Second, register at the local municipality or equivalent administrative office if required by the jurisdiction; many European destinations require residents to register within the first seven or fourteen days of arrival, and the registration certificate is a prerequisite for almost everything else. Third, activate or finalise local mobile phone service with a resident account (not just tourist roaming), because many local services and bank verifications require a local phone number. Other tasks — banking, utilities, healthcare, schooling — can wait until week two or three, but these three should not.
Banking is typically the slowest element of the first 90 days because local banks in most jurisdictions require significant documentation before opening accounts for new residents. The typical timeline is two to six weeks from initial application to active account, with some jurisdictions (Switzerland notably) taking longer and some (UAE and Singapore) able to complete the process faster for qualifying applicants. Required documentation typically includes the residency permit or card, proof of local address (rental lease or property deed), tax identification number from the destination jurisdiction, source of funds documentation, and in some cases personal references. Some jurisdictions require the applicant to appear in person at a specific branch for the initial meeting. The specific bank choice matters — international banks with dedicated expat services (HSBC, Credit Suisse, UBS, Emirates NBD for UAE) often handle new-resident applications more efficiently than purely local banks that may have limited experience with non-national clients. Applicants should begin the banking process within the first two weeks of arrival and should expect it to continue through the first month or longer.
Three common mistakes cause the most problems. First, delaying tax registration in the new jurisdiction — most destinations expect new residents to register with the local tax authority within a specific window (often 30 to 90 days of arrival) to establish the transition from previous tax residency, and delays can create gaps or overlaps in tax residency status that cause compliance problems later. Second, over-committing to the new jurisdiction before the residency status is fully confirmed — buying property, signing long-term leases, or cutting ties to the previous jurisdiction before the destination residency is formally granted can leave applicants in an uncomfortable position if the residency application encounters delays or complications. Third, underestimating the schooling and family adjustment timeline — children and spouses frequently need longer than the main applicant to adjust to the new destination, and relocations where the main applicant prioritises tax and business setup over family integration often produce dissatisfaction in the first year that can derail the entire relocation. Specialist advisors can help manage all three risks, but applicants should plan for each specifically rather than assuming they will work out on their own.
The timing and specific notification requirements depend on the previous jurisdiction, but most developed countries require formal notification of departure or change in tax residency status within a specific window. The UK requires submission of Form P85 (for individuals leaving the UK to work abroad) or similar declarations as part of the Self Assessment tax return covering the year of departure; the notification should be made as soon as the UK tax residency has actually ceased under the Statutory Residence Test, typically in the tax year of departure. The US has different requirements for US citizens (who continue to be taxed on worldwide income regardless of residence) versus US residents who are not citizens (who can terminate US tax residency through specific procedures). Most European countries require a change of tax residency form to be submitted to the local tax authority, with the effective date aligned to when the individual actually ceased being tax resident under local rules. Specialist tax counsel in both the exit and entry jurisdictions should coordinate on the specific timing and documentation to ensure the transition is clean and does not create tax liability gaps or overlaps. The first 30 to 60 days of the new residency are typically when the exit-side notifications should be completed.
