Why do some small islands become rich? And how does money move across the ocean?
A tax havenA country where people and companies pay very little tax. It's like a shop where everything is 90% off — but for taxes! Some countries do this on purpose to attract money from around the world. is a place where companies pay very little tax. Imagine if your allowance was taxed 10% in Singapore, but only 1% in Mauritius. Where would you keep your money?
Mauritius is one of these places. Many big companies set up offices there — even if they don't sell anything to Mauritians — just to pay less tax.
When a company in Singapore wants to invest in Africa, the money often goes through Mauritius first. This is called an offshore companyA company that is registered in one country but does business in another. Like having a Singapore-registered company that only sells things in Malaysia. The company is "offshore" from where the actual business happens..
Why? Because Mauritius has special agreements with many countries that make moving money cheaper and easier. It's like having a VIP pass that lets you skip the queue at every theme park in the world.
Mauritius wasn't always a money island. 50 years ago, it was mostly sugarcaneA tall grass plant that looks like bamboo. When you squeeze it, sweet juice comes out. That juice is boiled to make sugar. Mauritius was once covered in sugarcane farms! farms. Over 90% of their money came from selling sugar.
But sugar prices went up and down. So Mauritius decided to become a financial hubA city or country where lots of banks, investment companies, and financial services are based. Like how Singapore is a financial hub for Asia, Mauritius became one for Africa. instead. Smart move!
Some people say tax havens are unfair. If big companies don't pay taxes, then the government has less money for schools, hospitals, and roads.
Other people say tax havens help poor countries attract investment. What do you think?
Singapore is also a financial hub! But it's not called a tax haven because it follows more international rules. Still, Singapore's low taxes (compared to other countries) is one reason so many companies set up here.
Connection: Mauritius and Singapore are both small islands that became rich by being good places for money to flow through. But they did it in different ways.
A company in Japan wants to invest in a farm in Kenya. Why might they set up an office in Mauritius first?
Ask your parents: "If you could keep your money in any country, would you? Is it fair to pay less tax just because you can?"
Mauritius is officially a tax havenA jurisdiction with intentionally low or zero tax rates, minimal financial transparency, and legal frameworks designed to attract foreign capital. The OECD maintains a "grey list" of countries that don't meet international tax standards. Mauritius was on it until 2021. — one of the few left after global crackdowns. In 2020, the EU blacklisted Mauritius. To get off the list, Mauritius had to raise its corporate tax to 15% and prove that companies actually had real offices and employees there (not just a mailbox).
The paradox: Tax havens help rich people and companies avoid taxes that would otherwise fund public services. But they also bring investment to small islands that have few other resources. Is the money worth the cost?
An offshore companyA legal entity registered in a jurisdiction where it has no significant business operations. For example, a tech company registered in Mauritius that develops software in India and sells to customers in Europe. The company is "offshore" from its actual operations. Critics call this "profit shifting" — moving profits to low-tax countries while keeping operations in high-tax ones. in Mauritius works like this:
1. A Singapore company wants to invest in an African mining project
2. Instead of sending money directly, it creates a Mauritius company
3. The Mauritius company invests in Africa
4. Profits flow back to Mauritius (low tax) instead of Singapore (higher tax)
5. The Singapore company pays less tax overall
This is legal. But is it right? That's the debate.
In 1968, when Mauritius became independent, over 90% of its export earnings came from sugar. This is called the resource curseWhen a country relies too heavily on one natural resource (like oil, diamonds, or sugar). The problem: when prices crash, the whole economy crashes. Also, countries with easy resource money often don't develop other industries, skilled workers, or good governance. It's called a "curse" because having valuable resources should be a blessing — but often isn't. — when a country depends on one thing, and that thing's price crashes, the whole country suffers.
Mauritius avoided the curse by diversifying. First into textiles, then tourism, then financial services. Today, financial services contribute more to GDP than sugar ever did. The Mauritius MiracleThe transformation of Mauritius from a poor sugar island (GDP per capita ~$200 in 1968) to Africa's wealthiest country (GDP per capita ~$11,000 today). Economists study this as a rare example of successful economic development in Africa. Key factors: property rights, rule of law, export processing zones, and strategic use of tax policy. is studied in economics textbooks worldwide.
Arguments FOR: Tax competition keeps governments honest. If a country taxes too much, companies leave. This forces governments to be efficient. Also, developing countries need FDIForeign Direct Investment — when a company from one country invests directly in another country (building a factory, buying a company, starting operations). Unlike "hot money" that flows in and out quickly, FDI is long-term and creates jobs. Mauritius attracts FDI because of its tax treaties. to grow, and low taxes attract it.
Arguments AGAINST: The OECD estimates that tax havens cost governments $100-240 billion in lost tax revenue every year. That's money that could fund schools, hospitals, and infrastructure. Developing countries lose the most because they rely more on corporate tax.
Your turn: If you ran a small island with no natural resources, would you become a tax haven? What's the alternative?
Both are small islands that became wealthy through finance. But they took different paths:
Singapore: Low but not zero tax. Strong rule of law. World-class infrastructure. Attracts real business (HQ, manufacturing, trading). Not on any tax haven blacklist.
Mauritius: Very low tax. Specializes in treaty shoppingWhen a company routes investments through a country specifically to take advantage of that country's tax treaties with other nations. For example, a US company investing in India through Mauritius because the Mauritius-India tax treaty has lower rates than the US-India treaty. This is legal but controversial — India has been trying to close these loopholes. — using tax treaties to reduce taxes on investments flowing between countries. Was on EU blacklist until 2021.
Key insight: Both succeeded, but Singapore's model is more sustainable. Mauritius is now trying to transition from "tax haven" to "real financial hub" — building actual banking, insurance, and wealth management industries.
A US tech company earns $100M profit from European customers. It has a subsidiary in Mauritius with 3 employees. The Mauritius subsidiary holds the European IP license. How much less tax might they pay vs declaring the profit in the US (21% corporate tax)?
Ask your parents: "If you were the finance minister of a small island nation, would you lower taxes to attract companies, even if it meant less money for schools? Where's the line between smart policy and unfair competition?"
