Tax Residency: Optimization and Planning for HNWI

What is tax residency for individuals and why is it important for HNWI?

Tax residency is an individual’s status that determines how a country taxes their income and assets. For High-Net-Worth Individuals (HNWI), this concept is paramount, as a tax resident is generally obligated to pay taxes on their worldwide income, whereas a non-resident is taxed only on income sourced within that country. Correct understanding and planning of tax residency not only helps avoid double taxation but also significantly optimizes tax burden, preserving and increasing wealth.

It’s crucial to understand that immigration status (e.g., temporary or permanent residence) and tax residency for individuals are distinct legal concepts and do not always coincide. Obtaining a residence permit does not automatically make one a tax resident, and vice versa.

How is tax residency determined: criteria and tie-breakers

Determining tax residency often seems complex due to variations in national laws. However, there are general principles, criteria, and mechanisms for resolving residency conflicts, which are particularly relevant for international HNWI tax planning.

Key criteria for determining tax residency

  • 183-day rule: Many countries, including Russia and most EU nations, use the criterion of physical presence in their territory for at least 183 calendar days within any 12 consecutive months. However, this is just one test and rarely the sole determinant.
  • Permanent home: Availability of a permanent dwelling at the individual’s disposal.
  • Centre of vital interests: This criterion assesses where a person’s primary economic, social, and family ties are located. It includes the place of residence of the family, business activities, social contacts, and asset management. In practice, between 2024–2026, the centre of vital interests often outweighs the formal count of days in disputed situations.
  • Habitual abode: Where the person spends most of their time, apart from their permanent home.
  • Citizenship: In some cases, citizenship can be a decisive factor if other criteria do not provide a clear answer.

Resolving residency conflicts: DTA tie-breakers

When an individual is considered a resident by the domestic laws of two countries simultaneously, the conflict is resolved using the provisions of Double Taxation Agreements (DTAs), employing so-called “tie-breakers.” The standard sequence according to the OECD Model Convention includes,:

  1. Permanent home.
  2. Centre of vital interests (family, business, social ties).
  3. Habitual abode.
  4. Citizenship.
  5. Mutual agreement procedure by competent authorities.

It’s important to note that from 2022–2023, certain provisions of Russia’s DTAs have been suspended, which may complicate the application of some tie-breakers and reduced rates. In such cases, the resolution of double taxation may occur through domestic tax credits, where provided.

Pre-immigration planning: key to successful change tax residency

For HNWI planning to change tax residency, it is critically important to start planning long before the actual relocation. This process is called pre-immigration planning, and its effective window is typically 12–24 months before the change of residency.

Pre-immigration planning is not an attempt to evade taxes but a legitimate preparation for relocation, allowing individuals to understand tax implications, resolve residency conflicts, mitigate the risk of double taxation, and ensure asset structures are transparent and documented. This is a key element of tax optimization for wealthy individuals.

Main objectives of pre-immigration planning:

  • Determining the moment of change tax residency: A clear understanding of when and by what criteria you will become a tax resident of the new country.
  • Reviewing worldwide income taxation: Understanding how the new country will tax your income from all sources, including foreign dividends, interest, capital gains, and rental income.
  • Asset restructuring: Selling or restructuring assets before relocation can significantly reduce the future tax base. For example, in some cases, it makes sense to establish the cost basis of assets (step-up basis) before moving to reduce future tax liabilities in the country of new residency.
  • Reviewing brokerage accounts and companies: Assessing the tax implications of owning foreign companies, trusts, and foundations.
  • Estate planning: Preparing or modifying estate plans, considering the laws of the new country and potential conflicts of rights.
  • Insurance policies: Analyzing the taxation of foreign insurance products and investment policies.
  • Documenting capital origin: Preparing documents on acquisition, portfolio valuation, and transaction history to confirm capital origin to banks and tax authorities.

A unique aspect of pre-immigration planning is that many decisions are only effective before relocation. After a change in tax status, some operations may have different tax consequences in the new country.

Domicile and residency: important distinctions for tax planning

The concepts of “tax residency” and “domicile” are often confused, though they have different legal natures.

  • Tax residency is a status tied to actual presence, dwelling, and centre of interests. It is determined for the current tax period and can change from year to year.
  • Domicile is a concept of common law. It is the country that a person considers their permanent “home” and intends to return to. Domicile is much more stable than residency: it is not automatically lost upon relocation, and it is confirmed by an aggregation of intentions and behaviors.

Historically, domicile held great significance in the UK, where, until April 2025, the non-dom regime allowed individuals without a British domicile to avoid paying tax on unremitted foreign income. However, starting April 6, 2025, the UK replaced this regime with one based on residency for taxing foreign income and capital gains.

Global transparency and CRS: what HNWI need to know about second tax residency

In the modern world, expecting “invisibility” of foreign accounts is generally unrealistic. The Common Reporting Standard (CRS) for automatic exchange of financial information covers over 120 jurisdictions. This means that the tax authorities of your country of residency will receive information about your financial accounts in other CRS-participating countries.

For HNWI, this necessitates maximum transparency and compliance with tax laws. Any attempts to conceal assets or income can lead to severe penalties and legal consequences. Therefore, judicious offshore tax optimization must adhere to legal frameworks and international agreements. The possibility of obtaining a second tax residency also requires careful analysis.

Popular beneficial regimes for new residents and tax optimization

Some countries offer attractive tax regimes for new residents, which can be an interesting option for HNWI when choosing a jurisdiction for changing tax residency. These countries include:

  • UAE: Known for its virtually zero tax burden on individual income.
  • Cyprus: Offers a non-dom regime, allowing new residents to exempt dividends and interest from taxes for 17 years.
  • Italy: A regime for new residents, allowing a fixed tax payment of 100,000 euros per year on all foreign income.
  • Portugal: NHR (Non-Habitual Resident) regime with beneficial taxation for certain types of income.
  • Switzerland: Attracts wealthy individuals with the possibility of agreeing on a fixed lump-sum tax.
  • Greece: Offers a non-dom regime with a fixed tax of 100,000 euros on foreign income.
  • Montenegro: In some cases, may offer attractive tax conditions.

Each of these regimes has its nuances and conditions that require detailed study and consultation with international tax planning specialists. The choice of the optimal regime depends on the individual situation, sources of income, and relocation goals.

Remember, there is no universal plan. Consulting with IKRA experts will help you develop an individualized plan that considers your citizenship, current and future tax residency, asset composition, ownership structure, family situation, business interests, and relocation goals. This will enable effective tax optimization for wealthy clients.

FAQ on Tax Residency and Optimization

What is tax residency for individuals?

Tax residency for individuals is a status that determines how a country taxes the income and assets of a particular person. Essentially, it’s a tax “registration” that defines the jurisdiction entitled to levy taxes on worldwide income or only on income sourced within its territory. This is a key aspect of HNWI tax planning.

What is the difference between tax residency and citizenship or residence permit?

Tax residency differs from citizenship or a residence permit. Citizenship is a legal bond with a state, granting certain rights and obligations. A residence permit (VNZh) is permission to live in a country. Tax residency, however, is primarily determined based on actual presence, availability of a permanent home, and the centre of vital interests, rather than solely formal immigration status. This nuance is very important when considering a change tax residency.

How does change tax residency occur, and what is second tax residency?

Change tax residency typically requires fulfilling certain conditions established by the new country’s legislation, such as physical presence in the country for more than 183 days a year, having a permanent home, and shifting the centre of vital interests. For High-Net-Worth Individuals, the process must be carefully planned as part of pre-immigration planning to avoid undesirable tax consequences and residency conflicts. A second tax residency can arise if an individual meets residency criteria in several countries simultaneously, which requires proper resolution through DTAs and expert guidance.

What is the “centre of vital interests” and why is it important for determining tax residency?

The “centre of vital interests” is one of the key criteria for determining tax residency, especially when an individual spends time in multiple countries. It includes the location of family, social ties, economic activities, main assets, and medical care. In disputed situations, this criterion often outweighs the formal count of days of presence, forming the foundation for tax planning.

How to optimize taxes abroad for HNWI?

Offshore tax optimization for HNWI requires a comprehensive approach, including pre-immigration planning, asset restructuring before relocation, utilizing beneficial tax regimes for new residents (if applicable), as well as judicious estate planning and asset ownership structuring. It is important to engage experienced international tax consultants to develop an individualized strategy and ensure tax optimization for wealthy clients.
