Mauritius GBC in 2026: Substance, Banking, Treaties and Cost

A Mauritius GBC is a real company in a real financial centre, and that is both the selling point and the cost. It is tax resident in Mauritius, it can hold a tax residence certificate and use Mauritius's 50-plus tax treaties, and on qualifying income it pays an effective 3%. In exchange, the law requires two Mauritius-resident directors, management and control from Mauritius, a licensed management company, an audit, and its principal bank account in Mauritius.

That last rule decides most of what follows. You don't shop for a bank for a GBC the way you do for a BVI or Seychelles company. The GBC comes with a Mauritius bank account by design, opened through your management company, usually in two to four weeks once the licence is issued. The real questions are whether your business fits the structure, which bank you put your principal account with, and whether your substance would survive a foreign tax authority asking where the company is really run.

This guide covers what a GBC is in 2026, the substance rules and what they cost, how GBC banking works in practice, what changed this year (FSC fees, the India treaty, Silver Bank), how a GBC compares with a UAE free zone company, and why GBC files fail.

What a Mauritius GBC is (and the Authorised Company alternative)

A Global Business Corporation, more formally a company holding a Global Business Licence (GBL) from the Financial Services Commission (FSC), is a Mauritius-resident company that is majority-owned by non-citizens and does its business principally outside Mauritius. It replaced the old GBC1 on 1 January 2019. The old GBC2 was abolished on the same date, and the grandfathered GBC2s lapsed on 30 June 2021.

Its replacement for low-substance use is the Authorised Company (AC). The two are often sold side by side, and they are not interchangeable:

The AC is the cheaper licence, but banks read it the same way they read any other non-resident company: the question becomes "where is this actually managed, and is it taxed there?" If your answer is "nowhere," an AC gets you the same rejections as a Seychelles IBC. Our breakdown of what banks accept for offshore companies covers that problem in detail.

The GBC is the one that fits operators who need a treaty-resident holding, treasury or service company with a credible tax home. Everything below is about the GBC.

The substance rules a GBC must meet

There are two layers, and most problems come from mixing them up.

Layer 1: the Financial Services Act (every GBC). Section 71 requires a GBC to be managed and controlled from Mauritius and administered by a licensed management company. In practice that means:

• at least two Mauritius-resident directors with enough independence of mind to actually decide things;
• board meetings in Mauritius with at least two of those directors present;
• the principal bank account in Mauritius at all times;
• accounting records kept at the Mauritius registered office;
• statutory financial statements prepared and audited in Mauritius.

Layer 2: the Income Tax Act (only if you claim the 80% partial exemption). To get the 3% effective rate, the GBC must also carry out its core income-generating activities (CIGA) in Mauritius, employ (directly or through its management company) an adequate number of suitably qualified people, and incur minimum expenditure proportionate to its activity. The FSC confirmed in January 2022 that the CIGA test applies only to GBCs claiming the exemption. A GBC that takes the foreign tax credit route instead does not need to show CIGA in Mauritius, though it still needs Layer 1.

The partial exemption only covers listed income types, not everything. As of 2026 the MRA's list includes foreign dividends, interest (excluding banks, deposit-takers, forex dealers, insurers and certain lenders), peer-to-peer lending interest, profits of a foreign permanent establishment, fund and asset manager income, ship and aircraft leasing, reinsurance, international fibre capacity, aircraft financing and services, and income of FSC-licensed Payment Intermediary Services and robo-advisory licence holders. Ordinary trading or consulting profit is not on the list: it is taxed at 15%, less any foreign tax credit.

The operator takeaway: a GBC is a 3% company for holding, financing and a short list of licensed activities. For a trading or services business it is a 15% company with treaty access. Anyone selling you "3% on everything" hasn't read the list. As always, take advice where you and the company's owners are tax resident: your home country's CFC and management-and-control rules can override all of this.

Two tax facts help: Mauritius has no capital gains tax as such and no withholding tax on dividends the company pays. And GBL holders are excluded from both the Fair Share Contribution (the levy on larger domestic companies that runs to June 2028) and the 10% alternative minimum tax that started on 1 July 2026 for certain domestic sectors.

How GBC banking actually works

Because the principal account must be in Mauritius, the GBC's banking starts with a Mauritius bank, not with whoever will take you. The Bank of Mauritius deposit insurance membership list for May 2026 names 13 banks, including MCB, SBM, Absa Bank (Mauritius), AfrAsia, Bank One, Investec and SBI (Mauritius). In practice the management company you appoint will have working relationships with a few of them and will introduce you.

What to expect:

• Sequence. Management company appointed, KYC pack done, company incorporated, GBL application filed with the FSC (around 10 business days for a plain GBC with a complete file, several weeks longer if it needs an activity licence), then the bank account, typically another 2 to 4 weeks. Budget 6 to 8 weeks end to end.
• Correspondents. Your USD clears through the bank's US correspondent, so the bank screens your counterparties with that correspondent in mind.
• Documents. A Mauritius bank's GBC checklist is long but predictable. Bank One's published list includes the GBL certificate, FSC fee receipt, constitution, registers of directors and shareholders dated within the past year, a structure chart, a UBO declaration, source of wealth and source of funds evidence for the beneficial owners, CRS/FATCA forms, and passport, proof of address, a bank or professional reference and a CV for every director, signatory and 20%+ shareholder. Certified copies only.

The account is the anchor, not the whole stack

A Mauritius bank is a good home for the holding company's funds, the dividends and the audit trail. It is not a payments engine. If the business needs EUR collections with a local IBAN, card acquiring or high-volume payouts, you add those on top: an EU bank or EMI account for collections, a PSP for cards. A GBC with audited accounts and a tax residence certificate is a much easier file at those institutions than a no-tax offshore company, which is the point of using it. Our guide to EMI vs bank multi-currency IBANs covers how to layer them, and the provider matcher shows which licensed banks and EMIs publicly accept or restrict your sector.

What Mauritius banks are wary of

The usual list:

• businesses with no link to the GBC's stated purpose (a "holding company" receiving card settlement from a nutra funnel);
• crypto flows without a licensed counterparty. Since the VAITOS Act came into force on 7 February 2022, doing VASP business in or from Mauritius without an FSC licence is an offence, so a GBC trading or exchanging crypto for clients needs that licence, not just a bank account;
• high-risk card verticals (gaming, adult, forex affiliates) where the bank would carry the correspondent exposure;
• counterparties in sanctioned or heavily monitored jurisdictions. US correspondents are re-papering foreign banks after this year's enforcement actions, and Mauritius banks pass that scrutiny on.

What changed in 2026

FSC fees went up on 1 July 2026. The amended Consolidated Licensing and Fees Rules (gazetted 30 June) set the GBL at USD 600 processing and USD 2,600 a year, and the Authorised Company at USD 600 and USD 1,400. The FSC extended this year's renewal deadline to 30 September 2026. If your management company hasn't confirmed payment, ask: an unpaid licence fee is exactly what a bank's periodic review catches.

The India–Mauritius protocol is in force. The 2024 protocol adding a Principal Purpose Test (Article 27B) entered into force on 10 August 2026, and India gave effect to it by notification on 13 October 2026. A treaty benefit can now be denied where getting it was one of the principal purposes of the arrangement. A tax residence certificate is still necessary evidence, but on its own it no longer settles the question. Real decision-making in Mauritius, minutes written at the time and a commercial reason for the structure matter more than ever. The protocol does not expressly remove the grandfathering of share investments made before 1 April 2017.

The Finance Act 2026 touched residence. EY's alert on the Act (No. 14 of 2026) reports a change, effective 12 August 2026, under which a company may be considered to have its central management and control outside Mauritius where its principal officer is non-resident. If your GBC's principal officer is you, living abroad, raise it with your management company and tax adviser now. Losing Mauritius residence would cost you the treaty access you set the company up for. The Act also requires beneficial-owner registers to record each owner's date of birth by 30 June 2027.

A Mauritius bank failed. Silver Bank, licensed in November 2021, was placed under a conservator in February 2024, moved to receivership on 30 March 2026, and lost its licence on 30 April 2026. Mauritius deposit insurance covers Rs 300,000 per depositor, and only for resident individuals: corporates, domestic or foreign, are excluded. A GBC's deposits are not insured. Pick the principal bank for its balance sheet, not for the friendliest relationship manager, and keep a second account for operating funds.

List status is clean. Mauritius left the FATF grey list in October 2021 and the EU high-risk third-country list with effect from 7 January 2022. It was not on the FATF June 2026 list of jurisdictions under increased monitoring. (The BVI was.) That matters at EU banks and EMIs that use list status as a hard filter.

Mauritius GBC vs UAE free zone company

This is the comparison most operators are actually making.

If you will run the business from Dubai and live there, a UAE company is usually the more honest structure, because the management and the people are where the company is. Our comparison of UAE free zones covers that side, including the free zone tax rules. If you need a treaty-resident holding or financing company and you are not moving, Mauritius is often the better tool. Plenty of groups use both: a UAE operating company owned by a Mauritius holding.

Why GBC files fail

1. Substance on paper only. Two resident directors who sign whatever arrives, board meetings that are a formality, decisions made by email from another country. That fails the FSC's management-and-control test, a foreign tax authority's residence test, and now the India PPT.
2. Claiming 3% on income that isn't on the list. Trading or consulting profit booked as "exempt" gets reassessed at 15%, and it makes the audit qualified or awkward. Banks read the audit.
3. The wrong business in the wrong wrapper. A GBC can't carry on business in Mauritius beyond incidental activity. A crypto or payments business needs the matching FSC licence on top of the GBL.
4. Weak source of wealth. The FSC, the management company and the bank all vet the beneficial owners. "Trading profits" without statements, contracts or tax returns behind them is the most common reason a bank asks for more and then stops replying.
5. No commercial story. Banks and treaty partners both ask why this company is in Mauritius. "Because it's 3%" is not an answer. "Because it holds our African subsidiaries, raises the group's financing and is run by a finance team in Ebène" is.
6. Fees and filings lapse. A missed FSC fee or a late audit is the fastest route to a bank review, and banks typically check licence and filing status at their periodic KYC refresh.

The GBC setup that works

• A management company that does more than file forms. It provides the resident directors and the company secretary, and it should provide people who actually understand the business. Ask who the directors are and what else they sit on.
• Directors who decide. Board packs, minutes that record real discussion, and key decisions taken at board meetings in Mauritius. Keep the paper: under the PPT, minutes written at the time are your evidence.
• Clear income mapping. Before year one, list each income stream and whether it is partial-exemption income (with CIGA) or 15% income. Decide the exemption-or-tax-credit question per stream with your adviser.
• Two Mauritius banks, or one bank plus an EU account. The principal account at a well-capitalised Mauritius bank, a second account elsewhere for operating funds, and a payments layer that matches your sector.
• A source-of-wealth file you'd be happy to send to any bank. Statements, sale agreements, prior company accounts, tax returns. Building it after a bank freezes the account is far harder.
• A calendar. FSC fee by its due date, audit filed within 6 months of year end, tax return within 6 months of the end of the month the year ends, tax residence certificate renewed before you need it.

If you are deciding between Mauritius, the UAE, Hong Kong or a classic offshore company, start from where the business is run and who it banks with, then pick the wrapper. Our company formation and offshore corporate banking teams can map the structure and the bank stack together before you pay anyone a licence fee.
