The Vault Part 2: Where They Hide

The Global Geography of $9.5 Trillion: How Singapore Grew 400% in Four Years, Why Dubai Welcomed 9,800 Millionaires in 2025, and What the Cayman Islands' 100,000 Companies Actually Do

In 2020, Singapore had about 400 family offices. By 2024, that number hit 2,000—a 400% increase in four years. They now manage over S$90 billion ($67 billion USD). Why Singapore? Because in 2020, the government launched Section 13O/13U tax incentives that offer 0% tax on designated investments. Meanwhile, Dubai welcomed 9,800 millionaires in 2025 alone—while the UK lost 16,500. The UAE offers 0% tax on income, corporate profits, capital gains, inheritance, and property. And the Cayman Islands? Population 65,000. Registered companies: 100,000. Government revenue: $800 million per year—not from taxes (they have none), but from incorporation fees. Family offices don't just avoid taxes. They operate in a parallel financial system with its own geographic hubs, legal frameworks, and infrastructure. This is the map.

The Hierarchy: Tier 1 vs. Tier 2 Jurisdictions

Understanding the System

Not all tax havens are created equal. For family offices, jurisdictions fall into two categories:

Tier 1 (Lifestyle + Tax Optimization): Places where ultra-wealthy families actually live. Singapore, Dubai, Switzerland, Monaco, London. These offer:

  • World-class infrastructure (schools, hospitals, airports)
  • Political stability and rule of law
  • Quality of life (safety, culture, dining)
  • Tax benefits (ranging from low to zero)
  • Banking sophistication

Tier 2 (Pure Tax Structures): Places where money lives, but people don't. Cayman Islands, British Virgin Islands, Panama, Jersey, Guernsey. These offer:

  • Zero or near-zero taxation
  • Maximum secrecy and privacy
  • Minimal disclosure requirements
  • Holding company structures
  • But limited lifestyle amenities (you wouldn't raise kids there)

The sophisticated strategy? Use both. Live in Singapore or Dubai (Tier 1), but route investments through Cayman entities (Tier 2).

Let's examine each major jurisdiction.

Singapore: The Asian Wealth Magnet

The Explosive Growth

According to the Monetary Authority of Singapore (MAS), the city-state has experienced explosive growth in family offices:

SINGAPORE FAMILY OFFICE GROWTH:

2020: ~400 family offices
2024: 2,000+ family offices (400% increase)
Assets Under Management: S$90 billion+ ($67 billion USD)
New 2025 Rules (Effective April 10):
  - Minimum AUM: S$35 million ($25.6 million USD)
  - Must employ 2-3 investment professionals
  - Local business spending: S$280K-700K ($205K-$512K USD/year)
Approval Timeline: 3 months for fast-track applications

The Tax Incentive Structure

Singapore's appeal comes from Section 13O and Section 13U tax incentive schemes, which the MAS administers.

Here's how it works:

Section 13O (Single-Family Offices):

  • For family offices managing one family's wealth
  • Minimum fund size: S$20 million ($14.6M USD) - raised from S$10M in 2025
  • Requires fund manager company in Singapore (2+ investment professionals)
  • Minimum local business spending: S$200,000 per year
  • Tax benefit: 0% tax on specified investment income (stocks, bonds, funds)

Section 13U (Multi-Family Offices):

  • For offices managing multiple families
  • Higher minimum fund size: S$50 million ($36.6M USD)
  • Must employ 3+ investment professionals
  • Minimum local spending: S$500,000 per year
  • Tax benefit: Same 0% tax on designated investments

What the 2025 Rule Changes Mean

In July 2024, MAS announced new requirements taking effect April 10, 2025. The goal: filter out "brass plate" operations (shell companies with no real substance) and attract only serious family offices.

The changes include:

  • Minimum AUM increased to S$35 million (was S$20M for Section 13O)
  • Must have 2-3 investment professionals with relevant qualifications
  • Annual business spending requirement: S$280K-700K (depending on structure)
  • Fund manager must be based in "Grade A office space" in Singapore

The result? Despite the higher requirements, applications surged. Why? Because the tax savings still massively outweigh the costs.

Who's Actually There

Some notable families and individuals with Singapore family offices:

  • Ray Dalio (Bridgewater Associates founder) — operates family office in Singapore
  • Sergey Brin (Google co-founder) — Singapore family office structure
  • Mukesh Ambani (Asia's richest person) — Reliance family office presence
  • James Dyson (vacuum/technology billionaire) — moved family office to Singapore in 2019
  • Eduardo Saverin (Facebook co-founder) — renounced US citizenship, Singapore resident since 2012

The Complete Package

Singapore offers what Dubai can't quite match yet:

  • Political stability (uninterrupted PAP rule since 1959)
  • Rule of law (British common law system, ranked #1 in Asia)
  • World-class education (international schools, NUS, INSEAD)
  • Geographic position (between Asian markets and Europe/US)
  • English-speaking (official language, business-friendly)
  • Infrastructure (Changi Airport rated #1 globally)

The only downside? Cost of living. Singapore is consistently ranked among the world's most expensive cities. But for billionaires, that's irrelevant.

Dubai/UAE: The Fastest-Growing Hub

The 2025 Migration Wave

According to the 2025 Henley Private Wealth Migration Report, Dubai is experiencing the fastest growth in high-net-worth individuals globally:

DUBAI/UAE MILLIONAIRE MIGRATION (2025):

Millionaires arriving: 9,800 (highest in world)
UK millionaires departing: -16,500 (negative migration)
Current family offices: ~55 single-family offices (2023 estimate)
Projected growth: 100+ by 2027

TAX RATES:
• Personal income tax: 0%
• Corporate tax: 0-9% (free zones often 0%)
• Capital gains tax: 0%
• Property tax: 0%
• Inheritance tax: 0%
• Dividend tax: 0%

The Two Financial Free Zones

Dubai has two main jurisdictions for family offices, each with different advantages:

DIFC (Dubai International Financial Centre):

  • Established 2004, modeled on London financial district
  • Common law jurisdiction (not Sharia law)
  • Minimum capital: $50 million
  • Licensing timeline: 7-10 days
  • Independent courts (DIFC Courts, English as official language)
  • 100% foreign ownership, 100% profit repatriation
  • Prestigious address (preferred by established wealth)

ADGM (Abu Dhabi Global Market):

  • Established 2015 (newer, more flexible)
  • Common law jurisdiction
  • More flexible capital requirements (case-by-case)
  • Licensing timeline: 20-30 days
  • Similar legal protections to DIFC
  • Often lower setup costs

The Golden Visa Program

The UAE's Golden Visa program is a key driver of family office migration:

UAE GOLDEN VISA REQUIREMENTS:

10-Year Residency (renewable)
Property Investment Route: AED 3 million ($820,000 USD) property
Business Investment Route: Establish company with capital
Includes: Spouse, children, domestic staff
No minimum stay requirement (can live elsewhere, maintain tax residency)
No income tax ever (UAE constitution prohibits federal income tax)

The genius of this system: You can be a UAE tax resident without actually living there full-time. Many billionaires maintain Dubai residency (for tax purposes) while spending most of their time in London, New York, or elsewhere.

Why Dubai Over Singapore?

Dubai offers advantages Singapore doesn't:

  • True 0% tax: Singapore still taxes some income; Dubai taxes nothing
  • Faster setup: DIFC licensing in 7-10 days vs. Singapore's 3 months
  • Lower operating costs: No S$280K-700K annual spending requirement
  • Real estate ROI: 8-12% annual returns with 0% property tax
  • Geographic access: Between Europe, Africa, and Asia (different time zones than Singapore)
  • Lifestyle: Luxury shopping, world-class restaurants, beaches, golf

The downsides?

  • Less political stability than Singapore (though UAE has been stable for decades)
  • Newer financial center (less track record than Switzerland or Singapore)
  • Extreme climate (summer temperatures exceed 110°F/43°C)
  • Cultural restrictions (though far more liberal than other Gulf states)

Who's Moving There

Recent high-profile family office migrations to Dubai include:

  • Russian oligarchs (post-2022 sanctions, seeking non-Western jurisdiction)
  • British entrepreneurs (fleeing UK's 45% top income tax rate)
  • Indian billionaires (second homes, business expansion)
  • Crypto billionaires (Dubai is crypto-friendly with clear regulations)
  • African wealth (political instability driving capital flight)

Cayman Islands: The Pure Offshore Play

The Numbers Don't Make Sense (Until They Do)

The Cayman Islands presents a statistical anomaly that reveals how offshore finance actually works:

CAYMAN ISLANDS BY THE NUMBERS:

Population: 65,000
Registered companies: 100,000+
Ratio: 1.5 companies per resident
Government revenue (2022): $800 million
Revenue per capita: $12,000+
Source of revenue: 100% from fees (zero taxation)
Global banking rank: 4th largest financial center (2008)

TAX RATES:
• Corporate tax: 0%
• Income tax: 0%
• Capital gains tax: 0%
• Property tax: 0%
• Inheritance tax: 0%
• Import duties: 5-27% (main government revenue source)

How This Actually Works

The Cayman Islands doesn't have family offices the way Singapore does—with offices, staff, and operations. Instead, it serves as a legal domicile for holding companies, trusts, and investment vehicles.

A typical structure:

  1. Family lives in Singapore or Dubai (Tier 1 jurisdiction)
  2. Family office operates there (investment decisions, staff, operations)
  3. Holding companies registered in Cayman (legal ownership of assets)
  4. Investments flow through Cayman entities (zero tax on profits)
  5. Profits reinvested or distributed (family receives money in Singapore/Dubai)

As of 2008, the Cayman Islands were the fourth-largest financial center in the world, with more registered businesses than people. This isn't because 100,000 actual companies operate there—it's because 100,000 legal entities are registered there.

Who Actually Uses Cayman?

Multinational corporations:

  • Apple routes international sales through Irish-Cayman structures
  • Google uses "Double Irish with a Dutch Sandwich" (Cayman as final destination)
  • Nike has 73 subsidiaries in Bermuda and Cayman combined

Hedge funds:

Family offices:

  • Use Cayman holding companies to own real estate globally
  • Cayman trusts for generational wealth transfer
  • Cayman SPVs (Special Purpose Vehicles) for private equity investments

The Government Revenue Model

How does the Cayman government generate $800 million per year with zero taxation?

CAYMAN GOVERNMENT REVENUE SOURCES:

Company registration fees: $500-1,500 per company per year
Banking license fees: Hundreds of thousands per bank
Work permit fees: $1,400+ per foreign worker
Import duties: 5-27% on all imported goods
Tourism fees: Cruise ship fees, hotel taxes
Financial services fees: Trust registration, mutual fund fees

RESULT: $12,000+ per capita government revenue (higher than many developed nations with income taxes)

The model is ingenious: Don't tax the money, tax the infrastructure that moves it.

Switzerland: The Original and Still Champion

Why It Still Matters

Despite competition from Singapore and Dubai, Switzerland remains the gold standard for European and Latin American wealth:

SWITZERLAND FAMILY OFFICE LANDSCAPE:

Offshore wealth held: CHF 2.1 trillion ($2.4 trillion USD, 2022)
Family offices: 300-500 estimated (concentrated in Geneva, Zurich, Zug)
Key advantages: Political neutrality, banking secrecy (reduced but still strong), rule of law
Tax structure: Lump-sum taxation available (negotiate flat tax based on lifestyle, not income)
Primary clients: European old money, Latin American wealth, Russian oligarchs (pre-2022)

Switzerland's appeal isn't about zero tax (it's not zero). It's about:

  • Stability: Neutral in both World Wars, 700+ years of continuous governance
  • Privacy: Banking secrecy laws (weakened by international pressure, but still stronger than most)
  • Infrastructure: World-class private banks (UBS, Credit Suisse, Julius Baer)
  • Discretion: Cultural norm of privacy (Swiss don't talk about money)
  • Quality of life: Alps, lakes, safety, healthcare, schools

The Lump-Sum Tax Trick

For ultra-wealthy foreigners, Switzerland offers "lump-sum taxation" (forfait fiscal):

  • Available to foreign nationals who don't work in Switzerland
  • Tax calculated based on annual living expenses, NOT actual income
  • Typical rate: 5x annual rent or 7x annual living costs (varies by canton)
  • Result: Billionaire pays taxes as if they have $1-2M income, not $100M+

Example: If you rent a CHF 50,000/year apartment in Geneva, your taxable base might be CHF 250,000—even if you earn CHF 50 million globally. Your effective tax rate approaches zero.

The Arbitrage Strategy: Using Multiple Jurisdictions

The Sophisticated Approach

The most sophisticated family offices don't choose one jurisdiction—they use several simultaneously:

TYPICAL MULTI-JURISDICTION STRUCTURE:

TIER 1 (RESIDENCE):
• Singapore or Dubai (where family actually lives)
• Benefits: Lifestyle, 0-low tax, banking, schools

TIER 2 (LEGAL DOMICILE):
• Cayman, BVI, or Jersey (where entities are registered)
• Benefits: Zero tax, maximum privacy, flexible corporate law

TIER 3 (BANKING):
• Switzerland or Singapore (where money is actually held)
• Benefits: Banking sophistication, political stability

TIER 4 (ASSETS):
• Real estate in London, New York, Miami
• Art stored in Geneva Freeport
• Yachts registered in Cayman
• Private jets registered in Isle of Man

A Real Example (Anonymized)

Here's how a typical tech billionaire might structure their family office:

  1. Lives in Singapore with Section 13O family office (pays 0% on investments)
  2. Holding company in Cayman owns all major assets (zero corporate tax)
  3. Bank accounts at UBS Switzerland (privacy + stability)
  4. Real estate in London owned through Jersey company (reduced stamp duty)
  5. Art collection in Geneva Freeport (no import taxes, climate-controlled)
  6. Yacht registered in Cayman (flag of convenience, minimal regulations)
  7. Private jet registered in Isle of Man (lower registration fees, EU access)
  8. Philanthropy through Delaware foundation (US tax deduction, global grant-making)

Result: Global asset portfolio worth $1+ billion, effective tax rate under 5%, complete privacy on asset ownership.

The Migration Patterns: Who's Going Where

2025 Trends

Based on recent wealth migration data:

Biggest Gainers (Millionaire Inflows, 2025):

  • UAE: +9,800
  • Singapore: +3,500
  • USA: +2,200 (mostly Miami, Texas, Florida)
  • Switzerland: +1,500
  • Portugal: +800 (Golden Visa program)

Biggest Losers (Millionaire Outflows, 2025):

  • UK: -16,500 (tax increases, Labour government)
  • China: -15,200 (political uncertainty, COVID policies)
  • India: -4,300 (seeking second residency)
  • South Korea: -1,200
  • Russia: -1,000 (sanctions, war)

What This Means

The UK is losing nearly 2x as many millionaires as Dubai is gaining. Where are they going? Dubai, Singapore, Monaco, Switzerland, Miami.

China's outflows are driven by wealthy families seeking political diversification. India's outflows are mostly families maintaining dual residency (living in India, but holding Singapore/Dubai residency for tax optimization).

The geography of family offices reveals a parallel financial system that operates by completely different rules than the one normal citizens inhabit. In this system, you choose your tax rate by choosing your ZIP code. You can be a resident of a zero-tax jurisdiction while living elsewhere. Your companies can be registered where they pay zero tax, even if they operate globally. Your assets can be owned by entities in six different countries, each chosen for maximum advantage. And the best part? It's all legal. Singapore added 1,600 family offices in four years. Dubai welcomed 9,800 millionaires in 2025 alone. The Cayman Islands has more companies than people. This isn't tax evasion—it's tax optimization. And it's only available to the ultra-wealthy who can afford the $3.2 million per year it costs to run a family office. By 2030, 10,720 families will operate in this parallel system, managing $9.5 trillion. And they're not hiding in bunkers—they're living in luxury in Singapore, Dubai, and Geneva, operating in plain sight, completely legally, under rules designed specifically for them.
NEXT IN THE SERIES: Part 3 examines how family offices actually invest. We'll document why they prefer illiquid assets (real estate, private equity, art) that are hard to value and easy to underreport. We'll show how "fair market value" becomes whatever the family office's appraiser says it is. And we'll reveal the valuation games that let billionaires claim their $500 million art collection is only worth $50 million for tax purposes. The data will prove that family offices don't just avoid taxes on income—they engineer entire portfolios designed to minimize taxation at every level.
