Two destinations, two lifestyles, one thing in common: ultra-attractive taxation. Mauritius and Dubai attract thousands of expats every year looking for tax optimization. But these two "tax havens" could not be more different.
On one side, a French-speaking tropical island with a modest cost of living and a 15% flat tax. On the other, a futuristic metropolis with zero income tax but expensive living costs. This guide helps you choose. Check our pages on Mauritius and United Arab Emirates, or use the UAE vs Mauritius comparator.
1. Overview: Two Different Tax Models
Let's start with the big picture:
| Criteria | Mauritius | Dubai (UAE) |
|---|---|---|
| Income tax | 0% to 20% (progressive) | 0% |
| Corporate tax | 15% (effective 3% GBL) | 9% (0% in Free Zone) |
| Capital gains | 0% | 0% |
| VAT | 15% | 5% |
| Cost of living (single) | EUR 800/month | EUR 2,200/month |
| City center rent | EUR 550/month | EUR 1,800/month |
| Language | French, English, Creole | Arabic, English |
| Tax treaty with France | Yes | Yes |
| Inheritance tax | 0% | 0% |
In short: Dubai wins on income tax (0% vs 15%). Mauritius wins on cost of living (2-3x cheaper) and effective corporate tax via the GBL regime (3% vs 9%).
2. Income Tax: 0% vs Progressive Flat Tax
Dubai: Zero Income Tax
This is Dubai's knockout argument. The UAE levies no personal income tax at all. Whether you are an employee, freelancer or investor, you keep 100% of your gross income. No brackets, no filings, no declarations. Zero.
This applies to all residents regardless of nationality. It covers salaries, business income, dividends and capital gains. For details, read our complete guide to Dubai taxes.
Mauritius: Progressive Flat Tax Up to 20%
Mauritius applies a progressive system:
- Up to MUR 500,000 (~EUR 10,000): 0%
- MUR 500,000 to 1,000,000 (~EUR 10,000 to 20,000): 10%
- Above MUR 1,000,000 (~EUR 20,000): 20%
For an expat earning EUR 80,000/year, the effective rate is around 18%. More than Dubai, but far less than France (40-50%). And the total absence of capital gains tax partially compensates.
On EUR 80,000 income: you pay EUR 0 tax in Dubai and about EUR 14,400 in Mauritius. But wait until you see the cost of living section.
3. Corporate Tax: The GBL Regime Changes Everything
Dubai: 9% CT (or 0% in Free Zones)
The UAE introduced a 9% corporate tax in 2023 on profits above AED 375,000 (~EUR 94,000). Companies in Free Zones can benefit from full exemption on qualifying income. Key Free Zones include DMCC, IFZA and DIFC.
Mauritius: 15% CT (but effective 3% with GBL)
The standard rate is 15%. But the Global Business Licence (GBL) regime changes everything. GBL companies receive a deemed foreign tax credit of 80%, bringing the effective rate down to 3%. One of the lowest in the world.
Requirements: real economic substance in Mauritius (office, employees, local activity). More details on the Mauritius Revenue Authority website.
For corporate tax: Dubai offers 0% in Free Zones, but Mauritius offers effective 3% via GBL with a network of 45+ tax treaties. Advantage Mauritius for international holding structures.
4. Cost of Living: Massive Advantage for Mauritius
This is where the comparison shifts. Dubai is an expensive city. Mauritius is an affordable island.
- Rent (city center apartment): Mauritius EUR 550/month vs Dubai EUR 1,800/month
- Monthly cost of living (single): Mauritius EUR 800/month vs Dubai EUR 2,200/month
- Monthly cost of living (couple): Mauritius EUR 1,300/month vs Dubai EUR 3,500/month
- Health insurance: Mauritius EUR 45/month vs Dubai EUR 200/month
- International school: Mauritius EUR 7,000/year vs Dubai EUR 15,000/year
An expat in Dubai spends roughly EUR 16,800 more per year than in Mauritius (rent + daily living). This surplus absorbs a big part of the 0% income tax advantage.
Take a freelancer earning EUR 80,000/year:
- Dubai: EUR 0 tax, but ~EUR 48,000 annual expenses (rent + living). Remaining: ~EUR 32,000.
- Mauritius: ~EUR 14,400 tax, but ~EUR 16,200 annual expenses. Remaining: ~EUR 49,400.
Surprise: at EUR 80,000/year income, you keep MORE money in Mauritius than in Dubai thanks to the lower cost of living. Dubai's break-even point is around EUR 120,000/year.
5. Lifestyle: Tropical Beach vs Futuristic Metropolis
Mauritius: The French-Speaking Tropical Paradise
- Climate: 25C annual average, tropical with rainy season (Dec-Mar)
- Language: French, English and Creole. You live in French daily.
- Internet: 50 Mbps average. Fine for remote work, but not exceptional.
- Safety: 5/10 score. Decent, with quieter areas in the north and west.
- French community: large and well-established. Associations, restaurants, French-speaking schools.
Mauritius is the flip-flop life. White sand beaches, turquoise lagoons, relaxed pace. Ideal for families, retirees and freelancers who want to slow down.
Dubai: The 21st Century Metropolis
- Climate: 28C average, but 40-45C in summer (June-September). The heat is a real issue.
- Language: Arabic and English. English is the daily working language.
- Internet: 200 Mbps average. Excellent for remote work.
- Safety: 9/10 score. One of the safest places in the world.
- French community: medium-sized. Less structured than in Mauritius.
Dubai is energy, skyscrapers, giant malls, non-stop business. If you love urban life, networking and professional opportunities, this is your playground.
6. Visas and Residence: How to Settle
Mauritius
- Premium Visa (digital nomad): 1 year renewable, minimum income USD 1,500/month (~EUR 1,380). Free.
- Occupation Permit (investor): 10 years, minimum investment USD 50,000 (~EUR 46,000).
- Retirement Permit: 10 years, transfer of USD 1,500/month, minimum age 50.
The Premium Visa is one of the most accessible in the world. No fees, low income threshold, fast processing. More info on the EDB Mauritius website.
Dubai
- Virtual Working Programme (digital nomad): 1 year, minimum income USD 3,500/month (~EUR 3,200). Cost: USD 287.
- Free Zone Visa (entrepreneur): 2 years, company setup in a Free Zone. From EUR 5,000/year.
- Golden Visa (investor): 10 years, real estate investment of AED 2,000,000 (~EUR 500,000).
In Dubai, the most common visa for entrepreneurs is the Free Zone visa. You set up a company in a free zone like DMCC or IFZA, and you get a residence visa. The 10-year Golden Visa is reserved for major investors.
Mauritius is more accessible: free Premium Visa at EUR 1,380/month income. Dubai requires more: EUR 3,200/month minimum or EUR 5,000/year for a Free Zone.
7. Banking and Practicalities
Mauritius
Opening a bank account in Mauritius is easy. Local banks (MCB, SBM) welcome expats without difficulty. The Mauritian rupee (MUR) is stable. International transfers work well via SWIFT. Opening time: 1 to 2 weeks.
Dubai
Opening an account in Dubai is also easy once you have the visa. Major banks (Emirates NBD, ADCB, Mashreq) offer accounts in AED and USD. The dirham is pegged to the US dollar, providing exchange rate stability. Timeline: 1 to 2 weeks.
Both countries have a tax treaty with France, preventing double taxation. Note: Mauritius has signed treaties with 45+ countries, a major asset for international holding structures.
8. The Verdict: Mauritius or Dubai?
Let's be direct.
Choose Mauritius if:
- Your income is below EUR 120,000/year (low cost of living more than compensates the tax)
- You want to live in French daily
- You seek a relaxed lifestyle with beaches and nature
- You are building an international holding (GBL at effective 3% + 45 tax treaties)
- You have a family on a reasonable budget
- You are a retiree (accessible Retirement Permit, low cost of living)
Choose Dubai if:
- Your income exceeds EUR 150,000/year (the 0% tax makes a real difference)
- You want to live in a dynamic, connected metropolis
- Networking and business opportunities are your priorities
- You enjoy luxury, modern infrastructure and maximum safety
- You need ultra-fast internet (200 Mbps vs 50 Mbps)
Our take: for most French expats with mid-range income (EUR 50,000 to 120,000), Mauritius is the better choice. The low cost of living, French-speaking environment, GBL regime and accessible Premium Visa make it a more balanced option. Dubai becomes more attractive above EUR 150,000 in annual income, when the total absence of income tax makes a real net difference.

FAQ
Do you really pay 0% tax in Dubai?
Yes, on personal income. No tax on salaries, dividends or capital gains. However, companies pay 9% corporate tax on profits above AED 375,000 (~EUR 94,000), except in Free Zones where qualifying income is exempt.
Is the Mauritius GBL regime legal?
Yes. The Global Business Licence is an official regime recognized by the Mauritius Revenue Authority. It requires real economic substance (office, employees, local activity). Mauritius is not on the EU blacklist.
At what income level does Dubai become more profitable than Mauritius?
Around EUR 120,000 to 150,000/year. Below that, Dubai's high cost of living absorbs the 0% tax advantage. Above that, the 0% makes a real net difference.
Can you live in French in Dubai?
Partially. There is a French community, French schools and restaurants. But daily life runs in English. In Mauritius, French is a commonly spoken language in everyday life.
Do both countries have a tax treaty with France?
Yes. France has signed double taxation agreements with both the UAE and Mauritius. Check exit tax conditions before leaving France if your portfolio exceeds EUR 800,000. More details in our article on tax mistakes to avoid when expatriating.
