Meet the Mauritius Revenue Authority (MRA): The Country's Tax Administrator
The tax authority in Mauritius is the Mauritius Revenue Authority (MRA), a body corporate that administers and collects the bulk of the country's tax revenues under the supervision of the Ministry of Finance and Economic Development. For a foreign owner, this single institution is the counterparty for almost every tax obligation your Mauritian entity will carry, from registration to filing, audit, and dispute. Its official mandate sets out the scope of what it does and how it answers to the State.
This article explains how the MRA is structured, what taxes and reporting it oversees, how you register and file, the deadlines that apply, and the powers it holds in assessment and enforcement. It is written for non-resident business owners, investors, and their advisers weighing incorporation in Mauritius or maintaining a company already established there.
The Legal Mandate and Role of the MRA
The MRA was created as an agent of the State to run an integrated revenue system, and it collects roughly 90% of all tax revenues in the country. The Ministry of Finance keeps overall responsibility for the organisation and monitors how it performs.
Its statutory functions sit in the Mauritius Revenue Authority Act 2004: administering the Revenue Laws, assessing liability, collecting and accounting for tax, coordinating activities under those laws, and delivering public service that encourages voluntary compliance. The operational framework rests mainly on the Income Tax Act, the Value Added Tax Act, and the Financial Services Act.
In practical terms, the authority both raises assessments and enforces them. That combination of assessment, collection, and enforcement under one roof is what you deal with as a taxpayer.

What the MRA Administers and Oversees
The MRA manages corporate income tax, personal income tax, value-added tax, and customs duties. Corporate income tax reaches companies, trusts, trustees of unit trust schemes, collective investment schemes, foundations, and non-resident partnerships (sociétés).
VAT applies at a standard rate of 15% on supplies of goods and services, with registration becoming compulsory once annual turnover passes MUR 6 million. Several recent measures expand what the authority oversees, and they matter for higher-revenue foreign-owned structures.
| Measure | Effective | Who it reaches | Rate |
|---|---|---|---|
| Corporate Climate Responsibility (CCR) levy | Year of assessment from 1 July 2024 | Companies and resident sociétés, turnover above MUR 50 million | 2% of chargeable income |
| Fair Share Contribution | 1 July 2025 to 30 June 2028 | Corporates (excluding banks), chargeable income and supplies above MUR 24 million | 5% (standard rate) / 2% (3% reduced rate) |
| Qualified Domestic Minimum Top-up Tax (QDMTT) | Year of assessment from 1 July 2025 | Mauritius-resident entities in MNE groups with consolidated revenue of EUR 750 million or more | Top-up to 15% effective rate |
Mauritius levies no capital gains tax. It also imposes no withholding tax on dividends paid by a Mauritian company, and none on interest or royalties paid to non-residents, unless an applicable treaty provides otherwise.
The authority is also the country's competent body for international exchange of information. It administers the OECD Common Reporting Standard and, under a Model 1 agreement with the United States, receives FATCA data from Mauritian financial institutions and passes it to the IRS.
On treaties, Mauritius has concluded 45 double taxation agreements in total; the DTA register lists them. The country signed the OECD/G20 Multilateral Convention on 5 July 2017, indicating that 23 of its in-force treaties will be covered by the BEPS MLI while the remaining 19 are revised bilaterally.
Registering as a Taxpayer with the MRA
Every company must register with the MRA on incorporation, which produces a Tax Account Number (TAN). The TAN is the identifier you will quote for all tax dealings, and registration can be done through the MRA e-services platform or by lodging forms at MRA offices.
For employees who are not Mauritius citizens, e-filing access uses the identification number issued by the Passport and Immigration Office or another number issued by the Director-General. VAT registration runs through a simplified online facility, accessed with a National Identity Card, Business Registration Number, or TAN and password.
If you intend to claim treaty benefits, your company must hold a Tax Residence Certificate from the MRA. That certificate requires proof that management and control are genuinely exercised from Mauritius, which in practice means a local office, qualified personnel, and board meetings held there.
Failing to register for VAT is an offence. On conviction, the penalty can reach three times the tax involved and imprisonment for up to eight years.

The MRA e-Services Portal and Online Filing Tools
Filing in Mauritius is largely electronic. The e-Services portal lets taxpayers submit returns online and pay by direct debit or credit card, and an e-Filing Service Centre facility allows approved agents to file on a taxpayer's behalf. A service centre acting for you must hold written authority and arrange electronic payment of any tax, penalty, surcharge, or interest.
The portal handles a wide set of functions: filing and paying returns, applying for or retrieving a TAN, password recovery, e-appointments, monthly PAYE/CSG/NSF returns, VAT applications, the Tax Calculator, the Current Payment System, the Employee Declaration Form, and Portable Retirement Gratuity Fund returns.
A phased e-invoicing mandate is in effect. From 15 May 2024, taxpayers notified by the Director-General with turnover above MUR 100 million must issue e-invoices under the VAT Act e-invoicing regulations.
In-scope businesses transmit invoices in real time, in structured JSON format, to the MRA system for "fiscalisation"; each document receives an Invoice Registration Number and a QR code. Entities that are not VAT-registered, including non-resident or cross-border firms with no Mauritian VAT registration, fall outside this scope.
Filing and Payment Calendar: Key Deadlines for Taxpayers
The standard tax year runs 1 July to 30 June, though a company may keep its own accounting period. Most deadlines flow from your year-end rather than a fixed national date.
- Annual corporate income tax return: within six months of the accounting year-end, filed through e-services.
- Individual income tax return for year of assessment 2025–2026: 15 October 2025.
- Advance Payment System (used by larger taxpayers): quarterly payments and APS statements within three months after each quarter-end.
- Tax deducted at source: remitted by the following month, with the annual TDS return due by 15 August.
- VAT returns: within 20 days of the end of the relevant month or quarter; where both return and payment are electronic, the deadline extends to the end of the following month.
- FATCA and CRS returns for the 2024 calendar year: due by 31 July 2025.
- QDMTT return and payment: within 15 months of the fiscal year-end.

Assessment, Audit and Investigation Powers of the MRA
Mauritius runs a self-assessment system, so your business calculates, files, and pays on its own account. Audits follow a discretionary, risk-based approach with no published selection criteria, and larger taxpayers are more likely to be reviewed.
Certain requests reliably draw attention: a tax refund claim, a request for approval before liquidation, VAT deregistration, or removal from the register of companies. Information received through international exchange between tax authorities can also prompt an investigation.
The look-back windows are worth understanding before you structure timing. For income tax, the standard investigation window is the two years preceding the current year of assessment, lifted entirely where no return was filed or where fraud is found.
For corporate income tax, the Director-General cannot raise an assessment beyond three years preceding the current tax year, though there is no time limit on recovering tax already assessed. For VAT, assessments may extend beyond two years but not past four years after the last day of the taxable period, in cases of non-declaration, under-declaration, or overstated input tax.
The authority's information powers are broad. The Director-General can demand records from taxpayers and third parties, including banks; authorised officers may enter premises at reasonable times, inspect books and electronic records, take copies, and conduct field audits covering stock, machinery, and equipment.
Enforcement, Penalties and Dispute Resolution Channels
Penalties attach to both late filing and late payment, and they differ by tax. The figures below set out the core civil charges; criminal offences under the Income Tax Act and VAT Act can apply on top, carrying fines and imprisonment.
| Default | Penalty | Interest |
|---|---|---|
| Late income tax return | MUR 2,000 per month (max MUR 20,000) | — |
| Late tax payment | 5% of unpaid amount | 0.5% per month |
| Late VAT return | MUR 2,000 per month (max MUR 20,000) | — |
| Late VAT payment | 10% (2% for small enterprises) | 1% per month |
| Ignoring an MRA information request | Fine up to MUR 1 million on conviction | — |
If you disagree with an assessment, the first step is an objection to the MRA's Objections, Appeals and Dispute Resolution Department within 28 days, paying 10% of the assessed amount. The department has four months to issue a determination, and any tax due under that determination must be paid within 28 days.
Should the determination not satisfy you, you may make representations to the Assessment Review Committee within the same period, or ask the Director-General to refer the matter to the Alternative Tax Dispute Resolution Panel where conditions are met. There are no court fees for these mechanisms at the ARC or before the MRA.
The Ministry of Finance occasionally introduces a Tax Arrears Settlement Scheme, waiving penalties and interest on arrears under the Income Tax Act, VAT Act, or Gambling Regulatory Authority Act 2007, conditional on full payment by a set date and withdrawal of any pending case. Where no assessment exists and you need certainty on a point, you can apply for a formal tax ruling.
Contacting the MRA: Offices, Helpdesks and Support
The MRA head office sits at Ehram Court, Corner Sir Virgil Naz and Mgr Gonin Streets, Port Louis, with Customer Service Desks on the ground floor. The Taxpayer Services hotline is (+230) 207 6000, and general queries reach the head office at headoffice@mra.mu.
Online support runs through the MRA e-Services portal and a dedicated Individual Portal covering income tax e-filing, TAN application and retrieval, password recovery, e-appointments, and return submissions. Note that legislation posted on the MRA website is for convenience only; the official text is that published in the Government Gazette.
What the MRA Means for a Non-Resident Owner or Adviser
For a foreign owner, the headline is that the system is aligned with OECD standards and applies consistently. All registered companies, whether a Global Business Licence entity, an Authorised Company, or a domestic firm, face a single 15% rate on net profit, applied to local and foreign-source income at the base level.
Treaty access is conditional, not automatic. You need a Tax Residence Certificate from the MRA, which means demonstrating real management and control from Mauritius, including a local office, qualified people, and board meetings held there.
Filing obligations reach even light-footprint structures. An Authorised Company, holding activities predominantly outside the country, must still file an income return within six months of its year-end, and GBC companies report to both the MRA and the Financial Services Commission, plus CRS and FATCA filings where they apply.
Expect your data to move. Mauritian financial institutions identify account holders resident in any CRS jurisdiction and report balances annually to the authority's exchange channels, which forward the information to your home tax authority; under the Model 1 agreement, US persons are captured through the IRS reporting route.
Two changes deserve close attention from advisers. The pre-Finance Act 2021 non-residence exemption for trusts and foundations whose settlors and beneficiaries were all non-resident is closed to new structures, with grandfathering for existing ones running to year of assessment 2024/2025. Separately, India and Mauritius signed a protocol on 7 March 2024 introducing a Principal Purpose Test into their treaty; ratification status should be monitored before relying on that treaty.
The common failures for foreign-owned entities are predictable: thin substance behind preferential treatment, weak transfer pricing documentation, late returns and payments, and misreading treaty entitlements. Membership of the OECD Global Forum and the FATF, and compliance with transparency and anti-money laundering standards, means the jurisdiction is not grey-listed and that mainstream compliance expectations apply to anything you build there.
Conclusion
The MRA is the single body you will deal with for registration, filing, audit, and dispute, and its rules are built to the same international standards your home regulators recognise. For a non-resident owner, the practical work is straightforward but unforgiving on detail: register for a TAN, file on time through e-services, secure a Tax Residence Certificate if you want treaty benefits, and keep substance and transfer pricing documentation in order. Get those basics right and the system is predictable; neglect them and the penalties, look-back windows, and exchange of information leave little room to recover quietly.

Frequently Asked Questions
The Mauritius Revenue Authority (MRA) administers and collects tax in Mauritius, gathering roughly 90% of national tax revenue. It operates as an agent of the State under the Ministry of Finance and Economic Development, established by the Mauritius Revenue Authority Act 2004.
Every company must register on incorporation to obtain a Tax Account Number (TAN), which is the identifier for all tax dealings, and registration can be completed online through the e-services platform. VAT registration becomes compulsory once annual turnover exceeds MUR 6 million, and treaty benefits additionally require a Tax Residence Certificate from the MRA.
A company files its annual corporate income tax return within six months of its accounting year-end, through the MRA e-services portal. An Authorised Company that operates mainly outside Mauritius is still required to file within the same six-month window.
For corporate income tax, the Director-General cannot raise an assessment beyond three years preceding the current tax year, while the standard investigation window is the two years before the current year of assessment. Both limits fall away if no return was filed or if fraud is involved, and there is no time limit on recovering tax already assessed.
You lodge an objection with the Objections, Appeals and Dispute Resolution Department within 28 days, paying 10% of the assessed amount, and the department has four months to determine it. If the outcome does not satisfy you, you may make representations to the Assessment Review Committee or request referral to the Alternative Tax Dispute Resolution Panel, with no court fees for either route.
Yes, where applicable. Mauritian financial institutions identify account holders resident in CRS-participating jurisdictions and report balances annually to the MRA, which exchanges that information automatically with the relevant foreign authority; under the Model 1 agreement, US persons' details flow through the MRA to the IRS.
