The movement of high-net-worth individuals across borders has accelerated beyond all historical precedent. In 2024, an estimated 128,000 millionaires relocated internationally, according to Henley & Partners’ Private Wealth Migration Report. That figure is projected to reach 142,000 in 2025 — the highest ever recorded — and 165,000 by 2026. What was once a niche practice has become a mainstream strategic consideration for anyone with significant assets and the flexibility to relocate. The drivers are structural, the scale is unprecedented, and the implications for both source and destination countries are profound.
This analysis examines the key corridors, regulatory shifts, and strategic considerations shaping the global tax relocation landscape heading into 2026.
The Great Wealth Migration
The numbers are striking. According to Henley Private Wealth Migration data, the UAE led all destination countries in 2025 with a net inflow of 9,800 millionaires — a record — followed by the United States at 7,500 and Singapore at 1,600. On the departure side, the United Kingdom is the single largest source of outflows, losing an estimated 16,500 millionaires in 2025 alone — more than double its 2024 figure. China lost an estimated 7,800 and India 3,500.
The structural shift is visible in the family office ecosystem. Deloitte reports that the number of family offices globally reached 8,030 in 2024, with assets under management totalling approximately USD 5.5 trillion. By 2030, those figures are projected to reach 10,720 offices and USD 9.5 trillion in AUM. Knight Frank’s Wealth Report identifies over two million ultra-high-net-worth individuals globally — those with investable assets exceeding USD 10 million — a population increasingly willing to optimise their tax position through jurisdictional arbitrage.
The drivers behind this migration are not reducible to taxation alone. Quality of life, personal security, access to international schooling, the ease of conducting global business, and the geopolitical environment all factor into relocation decisions. However, tax optimisation remains the primary catalyst: when marginal income tax rates in the country of origin exceed forty or fifty per cent, and capital gains and inheritance taxes add further friction, the economic case for relocation becomes difficult to dismiss.
Regulatory Landscape Shifts
The global regulatory environment is in flux, and the direction of change is overwhelmingly towards greater taxation, increased transparency, and reduced flexibility for mobile capital.
United Kingdom — Non-Dom Abolition
The UK abolished its centuries-old non-domicile regime effective 6 April 2025, replacing it with a four-year Foreign Income and Gains (FIG) exemption available only to new arrivals. Existing non-doms lost their remittance basis entirely. A Temporary Repatriation Facility allows previously sheltered foreign income to be brought onshore at 12 per cent in years one and two, rising to 15 per cent in year three. HMRC has hired 400 additional compliance staff and is analysing approximately 400 GB of data on offshore structures. The government forecasts recovering GBP 500 million over five years from enhanced enforcement. The result has been the sharpest outflow of wealthy individuals in UK history — an estimated 16,500 millionaires in 2025 according to Henley data.
Portugal — NHR Closed, IFICI Introduced
Portugal’s Non-Habitual Resident programme, once the most attractive tax incentive in Europe, was closed to new applicants from 1 January 2024. The replacement — known as IFICI, or informally “NHR 2.0” — offers a 20 per cent flat rate on qualifying Portuguese-source income, with foreign income exempt for a period of ten years. Applicants must not have been tax resident in Portugal for the five years preceding application. The Golden Visa programme has been restructured: residential property investment in Lisbon and Porto is no longer eligible, though the fund investment route remains available from EUR 500,000. Portugal retains lifestyle appeal, but its fiscal proposition has narrowed materially.
OECD Pillar Two & Global Minimum Tax
The OECD’s Pillar Two framework establishes a 15 per cent global minimum effective tax rate for multinational enterprises with consolidated revenue exceeding EUR 750 million. The framework now encompasses 147 countries. The Income Inclusion Rule (IIR) took effect from January 2024, with the Undertaxed Profits Rule (UTPR) effective from 2025 for jurisdictions with tax rates below 20 per cent, and the remainder from 2026. While Pillar Two applies to corporate structures rather than individuals directly, it constrains the ability to shelter income through low-tax corporate vehicles — a strategy that has underpinned many HNWI tax plans.
Information Exchange & Transparency
The Common Reporting Standard now covers 126 of 171 Global Forum member jurisdictions committed to automatic exchange of financial account information. CRS 2.0, currently in implementation, expands coverage to crypto-assets and digital currencies. The UAE has committed to CRS crypto-asset exchanges by 2028. Separately, the US FATCA regime involves reporting from over 300,000 foreign financial institutions globally, with penalties of USD 10,000 to USD 50,000 or more for non-filing, and a 40 per cent penalty on undisclosed asset understatements. The era of financial opacity is effectively over.
Exit Taxes
Several major jurisdictions impose departure taxes that increase the cost of relocation and demand careful advance planning. The United States applies a mark-to-market deemed sale on all worldwide assets of covered expatriates, with an exclusion threshold of USD 890,000 for 2025. Australia imposes a deemed disposal at market value when tax residency ends. Canada applies a deemed disposition at fair market value on the day before departure. Germany levies an exit tax on holders of one per cent or more of a company’s shares. France taxes residents of ten or more years who hold shares exceeding EUR 800,000 or representing more than 50 per cent of a company. Norway requires deferred exit tax to be settled within twelve years. Notably, the UK does not impose a formal exit tax — though the abolition of the non-dom regime itself functions as a powerful inducement to depart.
Top Destinations: A Comparative View
United Arab Emirates
The UAE remains the dominant destination for HNWI relocation globally, attracting a record net inflow of 9,800 millionaires in 2025 (Henley). The proposition is straightforward: zero personal income tax, zero capital gains tax, zero dividend tax, and zero inheritance tax. Corporate tax stands at nine per cent on profits exceeding AED 375,000, though qualifying free zone entities engaged in international activities remain exempt.
The Golden Visa programme grants a ten-year renewable visa to property investors meeting a minimum threshold of AED 2 million. Tax residency can be established with as few as 90 days of physical presence per year — notably less than the 183-day standard applied in most other jurisdictions. A family of four can expect a cost of living of approximately USD 5,000 per month, excluding housing, in Dubai. The combination of fiscal efficiency, infrastructure quality, and strategic geographic positioning between Europe and Asia continues to make the UAE the default choice for the majority of relocating families.
Singapore
Singapore occupies a unique position as Asia’s premier wealth management hub. Personal income tax is progressive from zero to 24 per cent, with the top rate applying to income above SGD 1 million (effective from Year of Assessment 2024). There is no capital gains tax. Corporate tax stands at 17 per cent.
Entry for ultra-high-net-worth individuals is principally through the Global Investor Programme, which requires a minimum of SGD 200 million in AUM with SGD 50 million deployed in Singapore over five years. The family office route under Section 13O requires a minimum AUM of SGD 20 million and provides full income tax exemption on qualifying investments; the Section 13U scheme raises the threshold to SGD 50 million. Singapore is signalling that it wants quality over quantity: fewer but larger and more committed wealth creators, rather than a broad influx of tax-motivated migrants.
Switzerland
Switzerland’s lump-sum taxation regime (forfait fiscal) remains available to foreign nationals who do not engage in gainful employment within the country. The federal minimum taxable base is CHF 434,700 for 2025, with typical minimum annual tax obligations of CHF 200,000 to CHF 300,000 or more, depending on the canton. Approximately 5,000 individuals nationally participate in the programme, collectively generating over CHF 1 billion in cantonal tax revenue. However, the regime is not universally available — the cantons of Zurich, Basel-Stadt, Basel-Landschaft, Schaffhausen, and Appenzell Ausserrhoden have abolished it.
Monaco
Monaco offers zero income tax, zero capital gains tax, zero inheritance tax for direct heirs, and no wealth tax. Residency requires a minimum bank deposit of EUR 500,000 and physical presence of at least three months per year. The trade-off is cost: average property prices exceed EUR 52,000 per square metre, and a family monthly budget typically exceeds EUR 23,000. Monaco is a compelling option for individuals with very substantial liquid wealth who prioritise proximity to Southern Europe.
Caribbean Citizenship by Investment
The Caribbean CBI programmes offer an alternative pathway: second citizenship with zero income, capital gains, and inheritance tax, plus visa-free access to over 140 countries. Dominica requires a minimum contribution of USD 200,000 or real estate investment of USD 200,000. St. Kitts and Nevis requires USD 250,000 or USD 400,000 in real estate. Grenada, at USD 250,000 contribution or USD 270,000 in real estate, offers a unique advantage: access to the United States E-2 Treaty Investor visa, a feature no other Caribbean CBI programme provides. It should be noted that Malta’s citizenship-by-investment programme was ruled illegal by the European Court of Justice in April 2025 and closed in July 2025 — a reminder that CBI programmes carry regulatory risk.
Italy
Italy’s HNWI flat tax regime levies EUR 200,000 per year (2025) on all foreign-source income, regardless of amount, for a duration of up to fifteen years. Family members can be added at EUR 25,000 per person. However, the regime is scheduled to increase materially: the main levy rises to EUR 300,000 in 2026, with family add-ons doubling to EUR 50,000. Italy remains attractive for individuals with very high foreign income relative to the flat levy, but the direction of travel is towards reduced competitiveness.
The Cost of Getting It Wrong
The consequences of poorly planned relocation are severe and, increasingly, irreversible. Tax residency is not determined by the purchase of a property or the issuance of a visa — it is a factual determination based on the number of days spent in a jurisdiction, the location of economic and personal ties, and the application of treaty tie-breaker provisions.
The 183-Day Rule — and Its Variations
Most countries apply the standard 183-day test: spending 183 or more days in a jurisdiction in a tax year establishes tax residency. But critical variations exist. The United States employs a Substantial Presence Test using a weighted formula: all days in the current year, plus one-third of days in the prior year, plus one-sixth of days in the year before that. The UAE requires only 90 days for holders of permanent residence. Monaco requires a minimum of three months per year. Where dual residency arises, treaty tie-breaker rules apply in a defined hierarchy: permanent home, then centre of vital interests, then habitual abode, then nationality.
Individuals who relocate without properly severing their tax residency in the country of origin risk dual taxation — being taxed as residents of both the departure and arrival jurisdictions simultaneously. This is not a theoretical risk. Revenue authorities in the United Kingdom, France, Australia, and Canada have all pursued cases against individuals who claimed to have relocated but failed to demonstrate genuine departure through their pattern of life, business connections, and family arrangements.
Substance requirements are equally critical. Simply registering a company in a free zone and obtaining a residency visa does not, by itself, establish the kind of economic substance that will withstand scrutiny. With CRS covering 126 jurisdictions, FATCA involving over 300,000 reporting institutions, and CRS 2.0 extending to crypto-assets, the information available to tax authorities is comprehensive and cross-referenced. There is no margin for administrative neglect.
The cost of imprecise planning is not merely financial. It is the loss of certainty — the fundamental objective that motivates the relocation in the first place.
Planning Framework
A well-executed tax relocation is a multi-disciplinary exercise typically spanning six to eighteen months. It cannot be reduced to a visa application or a corporate registration. The following timeline, informed by advisory best practice, outlines the key phases.
Months 1–3: Research and Assessment. Identify candidate jurisdictions based on personal circumstances, family needs, business structure, and long-term objectives. Engage specialist legal and tax counsel in both the departure and destination jurisdictions.
Months 3–6: Pre-Departure Planning. Execute pre-departure tax planning: crystallise gains where beneficial, restructure corporate vehicles, address trust and estate implications, and establish the documentary record of intended departure.
Months 4–9: Immigration and Banking. Submit residency and visa applications, establish banking relationships and investment custody in the destination jurisdiction. The Golden Visa, GIP, or equivalent programme will dictate specific requirements and timelines.
Months 6–12: Asset and Estate Restructuring. Restructure asset holdings to align with the new tax domicile. Update wills, powers of attorney, and estate plans to reflect the new jurisdictional framework. Address any cross-border succession issues.
Months 9–15: Physical Relocation. Execute the physical move. Establish genuine personal ties in the destination: housing, schooling, social connections, banking. Build the documentary record of domicile change.
Months 12–18: Certification and Compliance. Obtain a tax residency certificate in the destination jurisdiction. File departure returns in the country of origin. Ensure all international reporting obligations — CRS, FATCA, and jurisdiction-specific requirements — are met.
The families who execute relocation most effectively are those who treat it not as an event but as a process — one that requires professional guidance, disciplined execution, and sustained attention to the evolving regulatory landscape.
