Mauritius and international tax transparency
Mauritius has made the strategic choice of full tax transparency by adhering to the main international regulatory frameworks for the exchange of information. This compliance is a fundamental pillar of the credibility of Mauritius as an international financial centre and guarantees the durability of the tax advantages offered by the jurisdiction.
Two major regulatory frameworks govern the exchange of tax information in Mauritius:
FATCA (Foreign Account Tax Compliance Act)
A US initiative from 2010 to combat tax evasion by US taxpayers holding accounts abroad. Mauritius signed a Model 1 IGA with the United States in 2014.
CRS (Common Reporting Standard)
A global OECD standard adopted in 2014 for automatic multilateral exchange between 100+ jurisdictions. Mauritius carried out its first CRS exchange in 2018.
FATCA/CRS compliance is perfectly compatible with legal tax optimisation in Mauritius. The exchange of information concerns the existence and balance of accounts, not the legitimacy of tax structures. The benefits of the Partial Exemption System and of DTAs remain fully effective.
FATCA: the American framework
Origins and objectives
FATCA (Foreign Account Tax Compliance Act) was enacted by the United States in 2010 as part of the HIRE Act (Hiring Incentives to Restore Employment Act). Its aim is to combat tax evasion by American taxpayers (US Persons) who hold accounts and financial assets abroad, by requiring foreign financial institutions (FFIs) to report these accounts.
FATCA provides for a punitive 30% withholding tax on all US-source payments (dividends, interest, proceeds from the disposal of US assets) made to financial institutions that do not comply with its requirements. This sanction is a powerful lever for compliance.
The Mauritius-United States intergovernmental agreement (Model 1 IGA)
Mauritius signed a Model 1 Intergovernmental Agreement (IGA) with the United States in 2014. This model provides for a government-to-government exchange of information, which simplifies the obligations of Mauritian financial institutions:
-
Collection by financial institutions
Mauritian FFIs identify and collect information on accounts held by US Persons (US citizens, permanent residents, entities controlled by US Persons).
-
Reporting to the MRA
FFIs report the information collected to the Mauritius Revenue Authority (MRA), and not directly to the IRS.
-
Government exchange
The MRA transmits the information to the American IRS (Internal Revenue Service) in accordance with the IGA protocol.
-
Reciprocity
The IRS transmits to the MRA certain information on accounts held in the United States by Mauritian tax residents.
Financial institutions covered by FATCA
Mauritian financial institutions required to comply with FATCA include:
- Commercial banks: MCB, SBM, AfrAsia Bank, Bank One, HSBC, Barclays (ABSA), etc.
- Insurance companies: offering investment products with surrender value (life insurance, unit-linked products)
- Investment funds: CIS, Expert Funds, private pension funds, private equity funds
- Management Companies: acting as agents or depositaries for GBCs
- Brokerage firms: stockbrokers, securities dealers, custodians
- Trusts and foundations: when they hold financial accounts on behalf of US beneficiaries
Information reported under FATCA
| Category | Information reported |
|---|---|
| Holder identity | Full name, address, American Tax Identification Number (TIN) (SSN or EIN), date of birth |
| Account information | Account number, name of the financial institution, balance or value at calendar year-end |
| Income | Total amount of interest, dividends and other income paid or credited to the account during the year |
| Disposal proceeds | Gross amounts of sales or redemptions of financial assets (shares, bonds, funds) |
CRS: the OECD's global standard
Overview of the Common Reporting Standard
The CRS (Common Reporting Standard), developed by the OECD and adopted by the G20 in 2014, is a global standard for the automatic exchange of tax information (Automatic Exchange of Information — AEOI). It is directly inspired by FATCA but applies multilaterally between more than 100 participating jurisdictions, thereby covering almost all of the world's financial centres.
Mauritius was one of the first countries in the Africa-Indian Ocean region to adopt the CRS, with a first exchange of information in 2018. This early adherence demonstrates the commitment of Mauritius to tax transparency and reinforces its position as a trusted financial centre.
How CRS works in Mauritius
The CRS operates according to a four-step process:
- Identification: Mauritian financial institutions identify account holders who are tax residents of a jurisdiction participating in the CRS
- Due diligence: institutions apply rigorous verification procedures to determine and confirm the tax residence of holders
- Annual reporting: information is reported to the MRA before 31 July of each year (for accounts of the preceding calendar year)
- International exchange: the MRA transmits the information to the tax authorities of partner jurisdictions before 30 September
Main exchange partner jurisdictions
| Region | Main jurisdictions |
|---|---|
| Europe | France, United Kingdom, Germany, Luxembourg, Belgium, Switzerland, Italy, Spain, Netherlands, Austria, Ireland |
| Asia-Pacific | India, China, Singapore, Hong Kong, Japan, Australia, Malaysia, South Korea, Indonesia |
| Africa | South Africa, Nigeria, Ghana, Kenya, Seychelles, Uganda |
| Middle East | United Arab Emirates, Bahrain, Qatar, Saudi Arabia, Kuwait, Lebanon |
| Americas | Canada, Brazil, Argentina, Mexico, Cayman Islands, BVI, Bermuda, Curaçao |
Information exchanged under CRS
The information exchanged under the CRS is similar to that of FATCA but applies to all participating jurisdictions:
- Identity: full name, address, jurisdiction(s) of tax residence, tax identification number (TIN), date and place of birth
- Accounts: account number, name and identification number of the financial institution, balance or value as at 31 December
- Income: total amount of interest, dividends, other income and gross disposal proceeds credited during the calendar year
Mauritian legal framework for the exchange of information
The implementation of FATCA and the CRS in Mauritius rests on a solid and comprehensive legal framework:
| Legal text | Purpose | Date |
|---|---|---|
| Income Tax Act (sections 76A-76F) | National legal basis for the automatic exchange of tax information | Amended in 2015 |
| Income Tax (Common Reporting Standard) Regulations | Detailed rules for the implementation of the CRS (due diligence procedures, reporting formats) | 2015 (regularly revised) |
| FATCA Model 1 IGA | Bilateral agreement between Mauritius and the United States for FATCA exchange | Signed in 2014 |
| Multilateral Convention on Mutual Administrative Assistance in Tax Matters | International legal basis for multilateral exchange of information | Ratified by Mauritius in 2015 |
| Data Protection Act 2017 | Protection of exchanged personal data; regulation of the use of information | 2017 (revised) |
| Financial Intelligence and Anti-Money Laundering Act (FIAMLA) | Additional anti-money laundering vigilance and reporting obligations | 2002 (regularly revised) |
Obligations of financial institutions
Due diligence procedures
Mauritian financial institutions must implement rigorous due diligence procedures to identify the tax residence of their clients. Procedures differ depending on the type of account:
- New accounts (individuals): mandatory self-certification at the time of opening, with verification of the consistency of the information declared
- New accounts (entities): self-certification + classification of the entity (FI, Active NFE, Passive NFE) + identification of controlling persons for Passive NFEs
- Pre-existing accounts (individuals): systematic review of existing data, search for indicators of foreign residence (address, telephone number, transfer instructions, power of attorney)
- Pre-existing accounts (entities): classification of the entity (Active/Passive NFE) and identification of controlling persons for Passive NFEs
Classification of entities
| Classification | Description | FATCA/CRS obligation |
|---|---|---|
| Financial Institution (FI) | Bank, insurance with investment products, fund, custodian, portfolio management company | FATCA/CRS reporting obligation: collection and reporting of client accounts |
| Active Non-Financial Entity (Active NFE) | Operating company (trading, services, industry, active holding managing a group) | Subject to reporting by its bank. No look-through on controlling persons |
| Passive Non-Financial Entity (Passive NFE) | Passive holding, investment company without an FI licence, portfolio company | Mandatory look-through: financial institutions identify and report controlling persons (shareholders/beneficial owners > 25%) |
Reporting deadlines
| Framework | Period covered | Reporting to the MRA | International exchange |
|---|---|---|---|
| FATCA | Calendar year (1 January — 31 December) | 31 July of the following year | 30 September (MRA to IRS) |
| CRS | Calendar year (1 January — 31 December) | 31 July of the following year | 30 September (MRA to partner jurisdictions) |
Impact on GBCs and investors
Impact on Global Business Companies
The impact of FATCA and the CRS on GBCs depends on their classification:
GBC classified as Financial Institution
Investment fund, management company, insurance: full obligation to implement FATCA/CRS due diligence and reporting procedures. Significant compliance cost (IT systems, dedicated staff, legal advice).
GBC classified as Active NFE
Trading, exported services, active holding: no obligation to report as a reporting entity. Must provide a self-certification to its banks and financial partners. Favourable classification as there is no look-through.
GBC classified as Passive NFE
Passive holding, portfolio company: its controlling persons (shareholders, beneficial owners holding more than 25%) will be identified and reported by the financial institutions holding the GBC's accounts.
Impact on individual investors
Investors holding accounts in Mauritius should be aware that:
- Their account information will be automatically transmitted to their jurisdiction of tax residence
- They must declare these accounts in their country of residence (an obligation independent of the CRS, which has existed for a long time in most countries)
- Failure to declare in the country of residence can result in severe penalties
In France, financial accounts held abroad must be declared annually (form 3916 / 3916-bis). The fine for non-declaration is EUR 1,500 per account (increased to EUR 10,000 for accounts in countries that have not signed an assistance agreement). In the event of regularisation, the increases are reduced.
OECD assessment of Mauritius
The OECD's Global Forum on Transparency and Exchange of Information for Tax Purposes has assessed Mauritius on several occasions. The results testify to the seriousness of Mauritian compliance:
| Assessment | Rating obtained | Comment |
|---|---|---|
| Phase 1 (legal and regulatory framework) | Compliant | Adequate and comprehensive legal framework for the exchange of information on request and automatically |
| Phase 2 (practical implementation) | Largely Compliant | Effective implementation with minor recommendations on certain operational aspects |
| AEOI (CRS automatic exchange) | Compliant | Automatic exchange operational, reliable and on time with 100+ jurisdictions |
Concrete benefits of compliance for users of Mauritius
- International credibility: Mauritius is recognised as a reliable and transparent jurisdiction by regulators, correspondent banks and institutional investors
- Easier banking access: international banks maintain solid correspondent relationships with Mauritian banks, facilitating international transactions and the opening of a bank account in Mauritius
- Protection against blacklisting: compliance prevents any listing on the blacklists of the EU, the OECD or the FATF, which would have disastrous consequences for structures based in Mauritius
- Legal certainty: investors and entrepreneurs benefit from regulatory predictability and legal protection against accusations of using tax havens
- Durability of tax advantages: compliance guarantees that legitimate advantages (Partial Exemption, DTAs, capital gains exemption) will not be called into question by the international community
Best practices for businesses and investors
-
Determine your classification
Identify whether your entity is a Financial Institution, an Active NFE or a Passive NFE. This classification determines the scope of your obligations and the impact on your shareholders.
-
Prepare self-certifications
Accurately complete the self-certification forms requested by your banks. Correctly indicate all your tax residences and TIN. Incorrect information constitutes an offence.
-
Declare your foreign accounts
Make sure to declare your Mauritian accounts in your jurisdiction of tax residence (form 3916 in France, FBAR in the United States, etc.).
-
Keep up-to-date records
Maintain complete documentation on your beneficial owners, your ownership structure and the history of changes of controlling persons. A corporate secretarial service can assist you with this administrative management.
-
Report changes
Any change of tax residence must be reported to your financial institutions within 90 days. A move, the acquisition of nationality or a change in tax status must be communicated proactively.
-
Consult a professional
FATCA/CRS rules are technical and their implications vary according to your situation. A specialised tax advisor can optimise your classification and minimise negative impacts.
FATCA/CRS and tax optimisation: full compatibility
FATCA/CRS compliance does not affect in any way the legitimate tax advantages of Mauritius. The effective rate of 3%, the exemption of capital gains, the absence of withholding tax on dividends and the benefits of DTAs are legal provisions of Mauritian law. The automatic exchange of information concerns the existence and balances of accounts, not the legitimacy of the structures — provided that substance and compliance are ensured.
Warning: FATCA/CRS obligations are complex and their implications vary according to your personal situation, your tax residence and the nature of your structures. The penalties for non-compliance are significant. Consult a qualified tax advisor for a personalised analysis.
