Legal residency criteria according to tax treaties

Introduction — The Global Rules Behind Where You “Belong”

In an increasingly interconnected world, wealth no longer has borders — but taxation still does. Every investor, entrepreneur, or expatriate must answer a deceptively simple question: “Where am I legally resident for tax purposes?”

The answer determines which country can tax your income, how your investments are treated, and whether you risk double taxation.

For individuals with global assets or multiple homes, the rules can seem opaque. Yet, the criteria are not arbitrary — they are defined by international tax treaties, guided by the OECD Model Convention and applied consistently across more than 3,000 bilateral agreements worldwide.

This article unpacks those rules, explaining how residency is determined under tax treaties, why it matters for investors and entrepreneurs, and how SBH Capital Partners structures compliant fiscal residency in Saint-Barthélemy, ensuring full tax neutrality within the framework of international law.

Part 1 — Understanding Legal Tax Residency

1.1. The Concept of Residency in Tax Law

In domestic law, residency defines which jurisdiction has primary taxation rights over your income and capital gains.
Every country applies its own rules — often based on one or more of the following:

  • Physical presence test: more than 183 days per year.
  • Permanent home test: where your habitual dwelling is located.
  • Center of vital interests: where your family, work, or economic ties are strongest.
  • Domicile or nationality: in some cases (notably the U.S. and U.K.), citizenship or domicile also triggers taxation.

However, when two countries claim you as resident, a tax treaty intervenes to determine which one prevails.

1.2. The Role of Tax Treaties

Bilateral tax treaties — based on the OECD Model Tax Convention (Article 4) — exist to:

  • Avoid double taxation;
  • Prevent tax evasion and treaty abuse;
  • Define residency “tie-breaker” rules; and
  • Clarify which state can tax specific types of income.

Without such treaties, global investors risk being taxed twice — once in their home country and again in the country where the income arises.

1.3. Why Residency Is Foundational

Your tax residency acts as a legal anchor for all other fiscal concepts:

  • It determines which country has first claim on your income.
  • It decides whether your global income is taxable or only local income.
  • It defines which treaties protect you internationally.

In short, your residency is your fiscal identity. Without clarity, your assets float in a grey zone of uncertainty.

Part 2 — The OECD Tie-Breaker Rules

When two jurisdictions claim you as a tax resident, Article 4 of the OECD Model Convention provides a step-by-step hierarchy — the famous “tie-breaker” tests — to identify your single, legitimate residence.

2.1. Step 1 — Permanent Home

“An individual shall be deemed to be a resident only of the State in which he has a permanent home available to him.”

A permanent home doesn’t need to be owned — but it must be available continuously. The presence of a primary dwelling (even rented long-term) can be decisive.

2.2. Step 2 — Center of Vital Interests

If you have homes in both countries, the next test examines where your personal and economic relations are closer — where your “center of vital interests” lies.

Authorities analyze:

  • Location of family and dependents,
  • Where income is earned,
  • Social and professional connections,
  • Banking, club memberships, and lifestyle patterns.

It’s not just where you sleep — it’s where you live economically and emotionally.

2.3. Step 3 — Habitual Abode

If your vital interests can’t be clearly identified, the next factor is where you habitually reside — the country where you spend most of your time during the year.

2.4. Step 4 — Nationality

If your habitual abode remains unclear, your nationality determines residency. This rarely applies but can be decisive for “digital nomads” or frequent travelers.

2.5. Step 5 — Mutual Agreement Procedure (MAP)

If none of the above clarifies residency, both countries’ tax authorities can negotiate under a Mutual Agreement Procedure, based on documentation and substance.

This hierarchy ensures that each individual has one single tax residence for treaty purposes — not two.

Part 3 — Residency Criteria for Companies

3.1. The “Place of Effective Management” (POEM)

For corporations, the OECD defines residency based on the place of effective management — the location where key business decisions are made.

This includes:

  • Board meetings,
  • Strategic decisions,
  • Accounting and record-keeping,
  • Local management and signatory authority.

If these occur in different jurisdictions, tax authorities may requalify the company’s residence — and retroactively tax profits.

3.2. Real Substance vs. Nominal Presence

A “registered office” alone is no longer sufficient. To be legally resident, a company must have real substance, including:

  • Local directors or managers,
  • Operational decision-making on-site,
  • Bank accounts and accounting managed locally,
  • Compliance with local corporate obligations.

This is the principle underlying SBH Capital Partners’ management framework: ensuring that all governance occurs within Saint-Barthélemy, thereby establishing indisputable fiscal residency.

Part 4 — How Tax Treaties Protect Global Investors

4.1. Elimination of Double Taxation

Tax treaties prevent overlapping claims through two main methods:

  • Exemption method: income taxed in one country is exempt in the other.
  • Credit method: taxes paid abroad are credited against domestic taxes.

Residency determines which method applies — hence, choosing the correct jurisdiction is critical.

4.2. Reduced Withholding Taxes

Residents of treaty countries often enjoy lower withholding tax rates on dividends, interest, and royalties.
For example, a resident of France investing in a treaty partner like Singapore may pay 10% instead of 25% withholding.

Without recognized residency, these advantages vanish.

4.3. Protection from Fiscal Arbitrage and Greylisting

Operating within treaty frameworks signals legitimacy. Jurisdictions recognized under OECD standards — such as Saint-Barthélemy — are transparent, cooperative, and fully compliant.

This avoids reputational risk, blocked bank transfers, or classification as an “offshore” entity.

Part 5 — Saint-Barthélemy: Treaty Logic Within French Law

5.1. A Unique Legal Position

Saint-Barthélemy is a French Overseas Collectivity under Article 74 of the French Constitution. It applies French civil law but operates under its own fiscal sovereignty.

This creates a rare balance:

  • Tax neutrality for residents,
  • Full legal protection under French jurisdiction,
  • Recognition under international treaties via France.

In practical terms:

  • Individuals resident for five consecutive years become exempt from French income, wealth, and capital gains tax.
  • Locally managed companies are considered Saint-Barthélemy tax residents — not French mainland entities.

5.2. Treaty Protection via France

As part of France, Saint-Barthélemy indirectly benefits from France’s extensive network of double taxation treaties.
While not all apply automatically, investors gain the same legal credibility and banking acceptance as any French entity.

This gives Saint-Barthélemy residents the best of both worlds:

  • Local tax neutrality,
  • Global legal recognition.

5.3. SBH Capital Partners’ Framework

SBH Capital Partners ensures that every client’s structure meets residency criteria:

  1. The company is registered and managed locally.
  2. All decisions are made in Saint-Barthélemy.
  3. Banking, accounting, and compliance occur under local oversight.
  4. Documentation satisfies OECD and CRS standards.

This guarantees that both individual and corporate residency are defensible under any tax treaty.

Part 6 — Building a Legally Recognized Fiscal Identity

6.1. Substance Creates Legitimacy

Whether personal or corporate, substance — physical presence, governance, and integration — is the key to establishing legal residency under treaty law.
A passport does not define residency; activity and evidence do.

6.2. Avoiding Grey Zones

Hybrid or undeclared residencies invite scrutiny. Maintaining two homes, mixed bank accounts, or remote company control creates ambiguity.
Under the CRS, this ambiguity can result in data being sent to multiple jurisdictions, increasing exposure.

6.3. The SBH Approach

At SBH Capital Partners, we help clients:

  • Build documented fiscal substance in Saint-Barthélemy,
  • Create locally managed companies with effective control,
  • Align residency status with investment and inheritance planning,
  • Maintain global compliance while preserving tax neutrality.

This transforms residency from a vulnerability into a strategic asset — one that protects wealth, credibility, and freedom.

Conclusion — Residency as the Foundation of Legal Sovereignty

Tax treaties are the world’s legal map of fiscal belonging. They determine who has the right to tax you, who must respect your exemptions, and where your wealth truly resides.

In a transparent, post-BEPS world, residency is not a loophole — it’s a legal position backed by documentation, substance, and strategy.

By establishing clear, compliant residency in Saint-Barthélemy, investors enjoy:

  • Fiscal neutrality,
  • International recognition,
  • Legal protection under French jurisdiction, and
  • A permanent defense against double taxation.

With SBH Capital Partners, residency becomes more than a status — it becomes the foundation of lasting, lawful sovereignty.

Because in international taxation, your greatest asset is not your wealth.
It’s where your wealth resides legally.
