Why this choice matters
Mauritius offers two flagship vehicles for international business: the Global Business Company (GBC) and the Authorised Company. They share the same underlying Companies Act, but they operate under different tax, substance, and supervisory regimes. The decision affects how the company is taxed, what it can do, how it is regulated, how it is perceived by banks, and the ongoing cost of running it.
Founders sometimes pick the lighter route to save fees up front, only to discover later that banking, treaty access, or licensing required a GBC from the start. Restructuring after the fact is possible, but it is rarely as clean as choosing well in the first place.
Side-by-side comparison
| Dimension | Global Business Company (GBC) | Authorised Company |
|---|---|---|
| Regulator | Financial Services Commission (FSC) of Mauritius. | Registrar of Companies, with FSC supervision of the licensed management company. |
| Tax residence | Tax-resident in Mauritius; access to the corporate tax regime, with a partial exemption available on certain foreign-source income, subject to substance. | Non-resident in Mauritius for tax purposes; management and control must be outside Mauritius. |
| Treaty access | Potentially eligible for a Tax Residence Certificate where substance conditions are met. | Not eligible for Mauritius tax treaty benefits. |
| Substance | Required: typically at least two Mauritius-resident directors with relevant competence, a local office, and operating expenditure consistent with the activity. | Not required in Mauritius; managed and controlled from outside. |
| Permitted activity | International business, holding, investment funds, treasury, regional headquarters, regulated services subject to licensing. | International business entirely outside Mauritius; cannot conduct business in Mauritius. |
| Banking perception | Generally well understood by Mauritius and regional banks; substance, audited accounts, and FSC supervision support the file. | Banking is possible but typically requires a stronger commercial narrative, clear UBO chain, and source-of-funds evidence. |
| Annual obligations | Audited financial statements, FSC reporting, tax return, and ongoing substance review. | Annual return and financial summary through the management company. |
| Setup timeline | Around three to six weeks once the KYC pack is complete, subject to FSC review. | Around two to three weeks once the KYC pack is complete. |
| Cost profile | Higher: management company, FSC fees, two resident directors, office, audit. | Lower: management company and government fees, no local substance requirement. |
When a GBC tends to be the better fit
- You want treaty access, investor-grade banking, or you operate in a sector that benefits from a regulated structure.
- You expect to hold a Mauritius licence (for example, investment dealer, payment intermediary services, fund manager, or family office).
- You plan to build real operations in Mauritius: directors, staff, office, services performed locally.
- You are pairing the company with a Mauritius residency or relocation plan.
- You expect institutional counterparties or investors who will run their own due diligence on the structure.
When an Authorised Company can be considered
- The activity is entirely outside Mauritius and does not require treaty access.
- The ownership and management are based abroad and willing to maintain real foreign management and control.
- The expected banking partners are comfortable with a non-resident, lightly regulated Mauritius vehicle, given the file.
- Cost and speed are prioritised, and the founder understands that licensing or substance changes may require a future migration to GBC status.
Practical banking considerations
For a GBC, audited accounts, FSC oversight, and Mauritius-resident directors usually reduce friction at onboarding, especially with Mauritius and regional banks. Banks will still expect a clear activity description, UBO chain, source of funds, and transaction-flow forecast, but the structure itself does part of the explaining.
For an Authorised Company, the structure does less of the work. Compliance teams typically want to understand why Mauritius was chosen, where management actually sits, how the company will operate without local substance, what the source of funds is, and which corridors and counterparties are involved. EMIs can be part of the early operating plan in either case, particularly where the activity is payment-led or multi-currency. Bank approval remains at the institution's discretion in every scenario.
Decision rule
Choose the structure that tells the strongest compliance story for the activity you actually plan to run, not for the cheapest set-up cost. If treaty access, licensing, institutional banking, or relocation are realistic next steps, a GBC is usually the safer starting point. If the activity is genuinely external, light, and the founder has the discipline to maintain foreign management and a clean banking file, an Authorised Company can be appropriate.
Next step
The right way to decide is to map the activity, owners, jurisdictions, and intended banking partners against both structures before the first form is signed. Brunel Advisory can run that comparison with you confidentially and help line up the incorporation, banking, and any relocation steps as one coherent plan.
