The post‑Brexit landscape and the OECD’s push for a global minimum corporate tax are reshaping how high‑net‑worth entrepreneurs think about citizenship, residency, and tax planning. While the United Kingdom is unlikely to impose sweeping new restrictions on its citizens, other high‑tax jurisdictions may tighten rules that affect the ability to move to low‑ or zero‑tax jurisdictions.
Global minimum tax and its ripple effects
- The OECD and similar bodies are drafting policies that require multinational companies—and, by extension, high‑income individuals—to pay a minimum tax rate (often cited around 11 %).
- Countries that have traditionally offered “brilliant systems” for tax avoidance are being pressured to align with these standards.
- The trend suggests that, over the next 5‑15 years, it will become harder for citizens of high‑tax nations (e.g., the UK, Canada, Australia) to relocate to low‑tax jurisdictions without facing back‑door tax obligations.
How Brexit changes the UK picture
- For UK citizens who are six‑, seven‑, or eight‑figure entrepreneurs, the immediate impact appears limited.
- The UK is expected to remain relatively open to its diaspora, with British embassies continuing to provide consular support abroad.
- Unlike the United States, the UK is not projected to adopt a strict “pay‑nothing‑else” tax regime for expatriates.
- The main risk is indirect: as other countries adopt the OECD minimum‑tax framework, the UK may find it more difficult to secure low‑tax residency options for its citizens.
Options for living and working in the European Union
| Path | Typical requirements | Tax implications |
|---|---|---|
| Ancestry‑based citizenship (e.g., Irish) | Proof of lineage to an EU country | Usually grants full EU citizenship with minimal tax burden if you remain non‑resident. |
| Golden visa programs | Significant investment (often €250 k‑€500 k) in real estate or business | Grants residency; naturalization may require several years of physical presence. |
| Freelancer visas | Demonstrated self‑employment income; sometimes paired with tax incentives (e.g., Portugal’s Non‑Habitual Resident regime) | Allows work in the EU but typically subjects you to local taxes on earned income. |
| Student visas | Acceptance into an EU educational institution | Primarily for study; limited work rights and subject to local tax on any income. |
- Portugal, Italy, and similar jurisdictions can combine freelancer visas with tax exemptions, making them attractive for digital nomads who do not wish to become full tax residents.
- Ireland offers an immigrant investment program that, while more expensive than other EU options, provides a clear pathway for UK citizens due to historic ties.
Practical considerations for nomadic high‑net‑worth individuals
- Assess long‑term tax exposure – Even if you can temporarily avoid taxes, the global minimum‑tax regime may eventually capture income earned abroad.
- Diversify citizenship options – Holding multiple passports (e.g., UK, Canadian, Irish) can provide flexibility if one jurisdiction tightens its rules.
- Plan for residency duration – Short‑term stays (up to six months) in the EU generally avoid tax residency, but longer stays trigger local tax obligations.
- Monitor policy developments – OECD proposals, EU tax directives, and individual country reforms (e.g., Barbados ending its two‑tier offshore system) can change the calculus quickly.
Bottom line
For successful entrepreneurs, the evolving tax environment does not spell immediate disaster for UK citizens, but it does signal a future where moving to low‑tax havens will involve more scrutiny and potential tax liabilities. Leveraging ancestry‑based citizenship, golden‑visa investments, or freelancer‑visa schemes can preserve mobility, provided the tax implications of each option are carefully evaluated.
