Client Profile

Detail Info
Names Michel & Catherine (anonymized)
Ages 63 and 60
Nationality French
Residence Aix-en-Provence, France
Situation Michel retiring from executive role; Catherine already retired
Net worth ~€2.2M
Composition €800K securities, €600K assurance-vie, €500K Aix apartment, €300K cash
Income Michel: pension €48K/year + portfolio income ~€30K/year

The Problem

Michel and Catherine had always planned to retire abroad. Their concerns:

Issue Detail
French pension taxation Pension taxed at progressive rates — up to 30% marginal
Portfolio income 30% PFU on all investment returns
IFI €2.2M total, but only real estate counts — still close to threshold
Inheritance exposure Two children, €2.2M estate → significant succession taxes above allowances
Cost of living Aix-en-Provence increasingly expensive for retirees
Climate Wanted warmer weather year-round

Michel asked: "We've worked our whole lives. We want to enjoy retirement without watching a third of our income go to taxes every year."


The Initial Plan: Portugal

Their first instinct was Portugal — close to France, good weather, large French expat community.

However, Portugal's NHR (Non-Habitual Resident) regime ended in 2024. Without NHR:

Tax item Portugal (post-NHR) Impact
French pension taxation 10% flat (if specific treaty provision applies) or progressive up to 48% Variable
Portuguese investment income Up to 28% on dividends/interest Comparable to France
Succession tax 10% stamp duty on Portuguese assets (no tax on foreign assets for direct heirs) Better than France
Cost of living Lower than France, but rising Moderate savings

Verdict: Without NHR, Portugal was only marginally better than France for tax purposes.


The Pivot: Mauritius

Catherine's cousin lived in Mauritius. After a 2-week visit, they fell in love with the island. And the tax situation was dramatically better.

Why Mauritius for Retirees

Factor France Mauritius
Personal income tax Up to 45% progressive 15% flat (0% on first MUR 390K)
Tax on French pension Up to 30% 15% (France-Mauritius DTA: pension taxed in country of residence)
Tax on portfolio income 30% PFU 15% (or 0% on certain capital gains)
Capital gains tax 30% PFU 0%
Inheritance tax Up to 45% 0%
Wealth tax (IFI) Yes (on French real estate) No equivalent
Cost of living High 30-40% lower

Mauritius Retirement Visa

Mauritius offers a specific visa for retirees:

Visa type Requirement Validity
Retired Non-Citizen Permit Transfer $1,500/month to Mauritius bank account 10 years, renewable
Premium Visa Proof of income/savings, health insurance 1 year, renewable

Michel and Catherine qualified for the Retired Non-Citizen Permit easily.

Pension Taxation Under the DTA

The France-Mauritius DTA determines where pensions are taxed:

Pension type Taxed where? Rate
Private sector pension (retraite complémentaire) Country of residence (Mauritius) 15%
State pension (retraite de base — régime général) Country of residence (Mauritius) 15%
Government pension (fonctionnaire) Country of source (France) French rates

Michel's pension was entirely private sector → taxed only in Mauritius at 15%.


Financial Comparison (Annual)

Income source France (tax) Mauritius (tax) Savings
Pension €48K ~€10,500 €5,700 (15% after allowance) €4,800
Portfolio returns €30K €9,000 (PFU 30%) €4,500 (15%) €4,500
Capital gains (realized) 30% 0% Variable
Annual tax savings ~€9,300+

Cost of Living Comparison

Item Aix-en-Provence Grand Baie, Mauritius Difference
Rent (2BR, quality) €1,500/month €1,150/month -€350/month
Groceries €600/month €400/month -€200/month
Dining out €400/month €250/month -€150/month
Health insurance €300/month (mutuelle) €500/month (international) +€200/month
Utilities €200/month €100/month -€100/month
Monthly difference -€600/month

Total Annual Benefit

Category Amount
Tax savings €9,300
Cost of living savings €7,200
Total annual benefit €16,500

Over a 20-year retirement: ~€330,000 in cumulative savings — before accounting for capital gains tax elimination and inheritance tax savings.


Succession Planning Impact

This was the decisive factor for Michel and Catherine.

Scenario France Mauritius
Estate: €2.2M, 2 children
Allowance €100K per parent per child = €400K N/A
Taxable €1.8M N/A
Tax rate Up to 45% 0%
Estimated succession tax €400K-€500K €0

By establishing Mauritius residency and progressively moving assets offshore, Michel and Catherine could pass their entire estate to their children tax-free.


Aix-en-Provence Apartment

Option Tax implication
Keep and rent Rental income taxed in France at 20% + 17.2% social charges
Sell immediately Capital gains tax with partial abatements (22+ years ownership)
Sell after 22 years of ownership Full income tax exemption, social charges exempt after 30 years
Decision Sell after reaching 22-year mark (2 years away) for maximum abatement

Key Takeaways

  • Portugal without NHR is no longer the obvious retirement destination — Mauritius and UAE are stronger options
  • The France-Mauritius DTA allows private pensions to be taxed at only 15% in Mauritius
  • Zero inheritance tax in Mauritius is a game-changer for families with €1M+ estates
  • Cost of living in Mauritius is genuinely lower — not just on paper
  • The Retired Non-Citizen Permit is straightforward with only $1,500/month income requirement
  • Selling French property should be timed carefully around the 22-year abatement threshold
  • Health insurance is the main extra cost — international coverage is essential

⚠️
Disclaimer: Pension taxation depends on the specific DTA provisions and the nature of the pension. Government pensions (fonctionnaire) are typically taxed in France regardless. Professional advice is required.
