International Tax Planning

International Tax Planning for Ultra High Net Worth Individuals represents a comprehensive discipline situated at the intersection of tax law, corporate structuring, and investment management. In the context of a global trend toward increasing tax transparency—through mechanisms such as CRS (Common Reporting Standard), FATCA (Foreign Account Tax Compliance Act), and OECD initiatives to combat Base Erosion and Profit Shifting (BEPS)—effective tax planning requires a deep understanding of international conventions, substance requirements, and regulatory developments. For a manager overseeing a large portfolio, tax planning is an integral part of the investment process: after-tax return is the only relevant indicator for assessing management effectiveness. The tax consequences of every investment decision—from the choice of jurisdiction for registering a holding company to the timing of profit realization—must be integrated into the investment process at the planning stage, not considered post factum.

CRS/AEOI and Automatic Exchange of Tax Information

The Common Reporting Standard (CRS) is a global standard for the automatic exchange of tax information, developed by the OECD and endorsed by the G20 in 2014. CRS obliges financial institutions (Reporting Financial Institutions) to collect and transmit information about non-resident financial accounts to the tax authorities of the account holder’s tax residency jurisdiction. As of 2025, more than 110 jurisdictions participate in CRS, including the UAE, which began automatic information exchange in 2018.

Information exchanged under CRS includes:

• Name, address, tax residency jurisdiction, and Tax Identification Number (TIN) of the account holder;
• Account number;
• Name and identification number of the Reporting Financial Institution;
• Account balance or value at the end of the reporting period;
• For custodial accounts: the total amount of interest, dividends, and other income;
• For depository accounts: the total amount of interest payments.

Automatic Exchange of Information (AEOI) is the practical implementation of CRS through bilateral and multilateral agreements on information exchange. The Multilateral Competent Authority Agreement (MCAA) is the main multilateral tool for AEOI, providing a standardized exchange procedure.

Practical implications of CRS/AEOI for UHNWI include:

• Full transparency of financial assets before tax authorities of the residence jurisdiction;
• Impossibility of concealing offshore accounts and structures;
• Necessity for proactive tax compliance and Voluntary Disclosure of previously undeclared assets;
• Penalties for non-compliance ranging from 10% to 200% of unpaid tax, depending on the jurisdiction.

CRS Due Diligence: Financial institutions conduct Customer Due Diligence (CDD) to determine clients’ tax residency, using indicators such as address, phone number, standing instructions for fund transfers, and power of attorney. Self-certification of tax residency is mandatory for all new clients.

FATCA (Foreign Account Tax Compliance Act) is the US analogue of CRS, obliging foreign financial institutions to report information on accounts of US persons to the IRS. FATCA has extraterritorial effect and applies a 30% withholding tax on US-source income for non-compliant institutions.

Substance Requirements and Holding Structures

Substance Requirements are a key element of international tax planning after the OECD BEPS Action Plans. Economic Substance Rules (ESR) require that companies registered in certain jurisdictions have a real economic presence consistent with their activities.

For the UAE, Economic Substance Regulations (Cabinet Resolution No. 57 of 2020) establish requirements for companies carrying out Relevant Activities: banking, insurance, fund management, lease-finance, headquarters, shipping, holding company, intellectual property, distribution, and service centre.

Holding Company Activity: A company earning income solely from dividends and capital gains from equity interests must have an adequate number of qualified employees, adequate expenditure, and adequate premises in the UAE.

In practice, this means:

• The presence of at least one qualified employee or director physically present in the UAE;
• A real office (a virtual office is usually insufficient);
• Holding board meetings in the UAE;
• Making key management decisions within the UAE.

Holding Structures for international investments:

• UAE Holding Company (ADGM, DIFC, or mainland) — advantages: zero income tax (Corporate Tax Law 2022 establishes 9% on profits exceeding AED 375,000, but qualifying holding companies can apply the Participation Exemption for dividends and capital gains);
• Treaty network — the UAE has 100+ Double Taxation Agreements (DTAs);
• Stable regulatory environment.

Participation Exemption: UAE Corporate Tax Law provides exemption from tax for dividends and capital gains on qualifying participations, subject to conditions—ownership threshold (5%+ participation), holding period (12+ months), subject-to-tax test (the subsidiary is taxed at a rate of at least 9%).

Pillar Two (Global Minimum Tax) is an OECD/G20 initiative to establish a minimum effective tax rate of 15% for large Multinational Enterprises (MNEs) with global revenues of €750M+. Pillar Two includes:

• Income Inclusion Rule (IIR): the parent company pays top-up tax up to 15% on profits of subsidiaries in low-tax jurisdictions;
• Undertaxed Payments Rule (UTPR): a backup mechanism when IIR is not applied;
• Subject to Tax Rule (STTR): a treaty-based rule for developing countries.

For Single Family Offices (SFO) and family structures, Pillar Two is generally not directly applicable (threshold is €750M revenue), but it influences investments in large corporations and PE portfolio companies.

Exit Taxation and Change of Tax Residency

Exit Taxation is a tax levied upon a change of tax residency on unrealized capital gains. A number of jurisdictions apply exit tax upon emigration:

• Germany: Wegzugsbesteuerung (Section 6 AStG) for participations in companies of 1%+;
• France: Exit Tax on unrealized gains for individuals who were residents for 6+ years (suspended for moves to EU/EEA, deferred for third countries);
• Netherlands: Exit tax on substantial participations (5%+) with the possibility of deferral when moving to the EU;
• USA: PFIC (Passive Foreign Investment Company) rules and Expatriation Tax (Section 877A IRC) for US citizens/green card holders upon renunciation of status.

Exit planning:

• Timing—realization of gains before emigration in a jurisdiction with a lower rate;
• Step-up in basis—some jurisdictions provide a step-up on immigration, resetting unrealized gains at the time of entry;
• Treaty protection—some DTAs limit exit taxation rights;
• Deferral mechanisms—some jurisdictions allow deferral of exit tax payment upon provision of a bank guarantee.

Treaty Networks and Their Use in Planning

Double Taxation Agreements (DTAs) define the rules for taxation of various types of income (dividends, interest, royalties, capital gains) in cross-border transactions.

Key provisions:

• Withholding Tax (WHT) rates—DTAs reduce or eliminate WHT on dividends (typically 0–15%), interest (0–10%), royalties (0–10%);
• Capital Gains—DTAs specify which jurisdiction has the right to tax upon the sale of assets;
• Beneficial Ownership—requirement of actual ownership of the income for treaty benefits;
• Limitation on Benefits (LOB) and Principal Purpose Test (PPT)—anti-abuse provisions limiting treaty shopping.

UAE treaty network: The UAE has concluded 100+ DTAs, including agreements with key investment jurisdictions—UK, France, Germany, India, China, South Korea, Singapore.

Practical application: A UAE holding company receiving dividends from a subsidiary in India may apply the UAE-India DTA to reduce WHT from 20% (domestic rate) to 10% (treaty rate).

Strategic Recommendations for UHNWI

• Determine your tax residency jurisdiction taking into account personal circumstances, lifestyle preferences, and tax implications;
• Create a holding structure with real economic substance;
• Ensure full CRS/FATCA compliance;
• Integrate tax planning into the investment process at the pre-investment analysis stage;
• Regularly review the structure in light of changes in international tax legislation (BEPS 2.0, Pillar Two implementation, EU DAC updates).
