Special Tax Regimes: Pitfalls and How Advisers Can Navigate Them

Brendan Harper Head of Asia and HNW Technical Services View profile

Expat tax regimes are becoming more common as high-tax jurisdictions compete to attract internationally mobile talent. These regimes offer temporary benefits, yet many clients do not appreciate their limits, complexity or the long-term consequences of relying on them.

Why Governments Introduce These Regimes

Many high-tax countries use special “expatriate” or “flat tax” regimes to attract skilled workers or high-value professionals. In this Technical Spotlight, we explore the key regimes across Utmost’s core markets:

These regimes can be compelling. However, they are also restrictive, temporary and, in some cases, poorly understood. Clients may enter them with unrealistic expectations or without a long-term plan.

The Pitfalls Advisers Should Watch For

1. Strict Qualifying Criteria

Many high-net-worth individuals consider relocating on retirement to live off savings, pensions and investment income. This profile does not meet the stringent employment-based conditions in France, Portugal or Spain.

Portugal’s NIR, for example, applies only to individuals with specific skills in narrow sectors. It also excludes foreign pension income from tax exemption, which can instead be taxed at rates up to 53%. France has equally complex employment-linked requirements.

The UK FIG regime is the least restrictive but still involves comprehensive reporting of worldwide income and gains. For clients with complex international structures, this can create administrative and compliance challenges.

2. Limited Time Frames

These regimes are temporary. Relief can last:

  • Four years under the UK FIG regime
  • Fifteen years in Italy
  • Five to ten years in France, Portugal and Spain

Once the period ends, clients become taxable on worldwide income and gains at full marginal rates. They may also fall within inheritance or wealth tax rules on global assets. If a client intends to remain in the country long-term, these regimes may only offer short-lived relief.

3. Onshore Income and Gains Are Not Covered

Most regimes apply only to offshore income and gains. Spain, France and Portugal provide relief for some employment income, but investment income and onshore gains often fall outside the preferential rules.

Clients who generate substantial local income or who dispose of domestic assets may find the regime offers limited practical value.

4. Cross-Border Connections Still Matter

Many high-net-worth individuals retain ties to other jurisdictions. They may hold assets abroad, have beneficiaries living overseas or plan to move again later in life. Expat regimes grant temporary relief but do not remove the need for long-term, cross-border planning. Planning is still required for local income tax, capital gains tax, inheritance tax and succession rules in other countries to which they are connected.

Special tax regimes can be appealing, but they are not a complete solution. Their strict criteria, temporary nature and limited scope mean advisers must help clients plan beyond the regime. The most robust strategies remain those that local residents would use, rather than relying solely on incentives designed for newcomers.

Insurance-based wealth solutions play an important role here. They help clients secure portability, manage tax exposure across borders and maintain long-term planning continuity even after preferential regimes expire.

Key Takeaways for Advisers

  • Expat regimes offer short-term benefits but come with strict conditions.
  • Relief is temporary, requiring planning that endures beyond the time threshold.
  • Most regimes do not shelter onshore income or gains.
  • Clients with international connections still need cross-border planning.
  • Insurance-based wealth solutions can provide continuity, compliance and portability.
