Founders who incorporate in Mauritius are usually chasing one number: a 3% effective corporate tax rate, legally, on qualifying foreign income. That figure is real, it is built into the law, and it has made this small Indian Ocean island one of the most respected offshore company hubs on the planet. The catch is that it comes with conditions most cheap-jurisdiction blogs never mention. Substance. Reporting. Real management.
This guide is the straight version. If you want to use this jurisdiction properly, you need to understand the two company types, how the partial exemption actually drops your rate, what substance the regulator now demands, and what the whole thing costs. Get those right and you have a clean, treaty-rich base. Get them wrong and you have an expensive shell that fails its first audit.

Why Incorporate in Mauritius at All
Plenty of places promise zero tax. Most of them are blacklisted, banked nowhere, and toxic to serious counterparties. Mauritius took a different road. It built a low-tax regime that international bodies actually accept, backed by real regulation and a deep treaty network. That credibility is the whole point.
The headline corporate rate is 15%. For a GBC, an 80% partial exemption on qualifying foreign income drops the effective rate to 3%. There is no capital gains tax. There is no withholding tax on dividends paid to non-residents. And Mauritius sits inside more than 45 double-taxation treaties, including strong ones with India and across Africa, which is why it became the preferred gateway for investment into those markets.
Here’s the kicker. Because Mauritius is a compliant, treaty-rich jurisdiction rather than a pure tax haven, banks open accounts for Mauritian companies far more readily than for shell companies registered in blacklisted micro-states. Set up a company here and you get the low rate and the bankability. That pairing is rarer than it sounds. Compare it with the EU route in our guide to incorporating in Cyprus.
GBC vs Authorised Company
The first real decision is which vehicle to use. The two main structures serve very different purposes, and choosing wrong is the most expensive mistake people make.
Global Business Company (GBC)
The GBC is tax-resident in Mauritius, which means it can access the treaty network. It pays the 15% rate, reduced to an effective 3% on qualifying foreign income through the 80% partial exemption. To keep that status it must meet economic substance requirements: real management and control in Mauritius, adequate qualified employees, a minimum level of local expenditure, and a Mauritian-resident director or two. This is the vehicle for anyone who wants treaty benefits and a genuine operating base.
Authorised Company
The Authorised Company is treated as non-resident for tax purposes. It is taxed only on Mauritius-source income, which for most international businesses means effectively nothing is taxed locally, but it cannot use the double-tax treaties. It is simpler and cheaper to run, with lighter substance demands, and suits pure holding or trading structures that do not need treaty access. Its management and control sit outside Mauritius.
| Feature | Global Business Company | Authorised Company |
|---|---|---|
| Tax residency | Resident in Mauritius | Non-resident |
| Effective tax on foreign income | 3% (after 80% exemption) | 0% locally (Mauritius-source only taxed) |
| Treaty access | Yes, 45+ treaties | No |
| Substance required | Yes, full economic substance | Lighter |
| Best for | Treaty planning, operating businesses | Holding, simple trading |
How the 3% Rate Actually Works
The number people quote is real, but it is not automatic. The 15% corporate rate applies to a GBC. The 80% partial exemption then exempts 80% of certain categories of qualifying foreign income, such as foreign dividends, interest, and income from specified activities. Tax falls on the remaining 20%, at 15%, which works out to a 3% effective rate on that income.
That exemption is conditional. The company must satisfy substance requirements tied to the income stream, meaning real activity in Mauritius, not a brass plaque. Fail the substance test and the exemption is denied, leaving you on the full 15%. This is exactly why a serious provider matters. The structure is only as good as the substance behind it. Many founders pair the company with an offshore bank account and review their exposure under the Common Reporting Standard before they start moving money.
How to Incorporate in Mauritius: Step by Step
Step 1: Choose your structure. Decide between a Global Business Company for treaty access and the 3% effective rate, or an Authorised Company for a simpler non-resident vehicle. Your business model and need for treaties drives this.
Step 2: Engage a licensed management company. Mauritius requires a licensed corporate services provider to act as agent, handle the regulator, and supply registered office and resident directors. This is mandatory, not optional.
Step 3: File for incorporation and the relevant licence. Submit the application to the Financial Services Commission and Registrar of Companies with due-diligence documents. In straightforward cases a GBC can be set up within days.
Step 4: Establish economic substance. For a GBC, put real management and control in Mauritius: resident directors, qualified staff or outsourced core functions, local expenditure, and genuine decision-making on the island. This protects the 3% rate.
Step 5: Open banking and maintain compliance. Open a corporate account, file annual returns and audited accounts, and keep substance documented. Ongoing compliance is what keeps the structure valid year after year.
What It Costs to Incorporate in Mauritius
Costs vary with structure and provider, but a realistic budget looks like this. These are indicative market ranges, not government fee schedules, and a quote from a licensed management company will be specific to your case.
| Item | Indicative cost (2026) |
|---|---|
| GBC setup (incl. licensing) | USD 3,000 to 6,000 |
| GBC annual maintenance | USD 5,000 to 12,000+ (incl. substance) |
| Authorised Company setup | USD 1,500 to 3,000 |
| Authorised Company annual | USD 2,000 to 4,000 |
| Audit (GBC, required) | From USD 2,000 |
The GBC costs more because real substance costs more. That is the point. A cheaper jurisdiction with no substance might look attractive until a bank, a treaty partner, or your home tax authority asks where the company is actually managed. Pairing your company with the right personal base matters too, which is why founders often look at residency options alongside the corporate structure. There is a bonus for those who go big: a qualifying business investment of USD 500,000 or more, held alongside 2 years of residence, can unlock an accelerated route to Mauritian citizenship under Section 9(3) of the Citizenship Act. The same capital that builds your company can also buy a second passport, far faster than the standard 7-year clock.
Common Mistakes Founders Make
- Choosing a GBC for treaty benefits, then failing to build real substance, which collapses the exemption back to the full 15%.
- Picking an Authorised Company and then expecting treaty relief it can never provide.
- Treating the 3% rate as automatic. It applies only to qualifying foreign income that meets the conditions.
- Ignoring home-country controlled foreign company rules, which can tax the profits anyway if you do not also fix your personal residency.
- Using a bargain provider with no real presence, then struggling to open a bank account or pass an audit.
Mauritius vs Other Company Jurisdictions
How does a Mauritius company compare with the usual alternatives founders consider? Here is an honest snapshot for 2026.
| Jurisdiction | Headline corporate tax | Effective on foreign income | Treaty network |
|---|---|---|---|
| Mauritius (GBC) | 15% | 3% with substance | 45+ treaties |
| Cyprus | 12.5% | Often near 0% on dividends | Broad EU network |
| UAE | 9% | 9% above threshold | Wide network |
| US LLC (non-resident) | 0% federal pass-through | 0% if no US-source income | Treaties via members |
| Bahamas | 0% | 0% but no treaties | Minimal |
Each has a place. A non-resident US LLC can be brilliant for simple online businesses with no US activity, which is why many founders weigh it against a Mauritius GBC; see how an offshore base works alongside incorporating in the Bahamas. The UAE suits Gulf-focused operations. But for treaty-driven planning into India and Africa, with bankability and a 3% effective rate, Mauritius is in a class of its own.

Final Thoughts
The decision to incorporate in Mauritius is not about finding the lowest number on a brochure. It is about pairing a genuinely low effective rate with credibility, treaty access, and banking that works. The 3% is real. So is the substance you must build to keep it. Do both properly and you have a structure that survives scrutiny, not one that crumbles at the first audit. Want a readiness check first?

The clock is ticking on the old tricks. Tax authorities are sharper, substance rules are tighter, and brass-plate companies are dying. A real Mauritius structure is the opposite of that, which is why it keeps winning.
