How to Register for VAT in Mauritius Online, Steps, Documents and MRA E‑services

Understanding how to register for VAT in Mauritius is now more urgent than ever for local businesses, foreign digital suppliers and sole traders alike. The compulsory registration threshold was lowered to MUR 3,000,000 effective 1 October 2025, bringing thousands of additional enterprises within the VAT net, while Mauritius extended VAT to certain cross‑border digital and electronic services from 1 January 2026. The Mauritius Revenue Authority (MRA) has simultaneously rolled out a simplified online registration portal, making the entire process, from form submission to certificate issuance, accessible through its e‑services platform.

This guide walks through every step of VAT registration online in Mauritius: who must register, which documents to gather, which MRA VAT forms to use, and how to navigate the portal without delays or rejections.

Quick decision checklist, do you need to register?

• Turnover test. Your taxable supplies have exceeded, or are likely to exceed, MUR 3,000,000 in the relevant period.
• Nature of supplies. You supply taxable goods or services, or, from 1 January 2026, in‑scope digital/electronic services, to customers in Mauritius.
• Voluntary option. Even below the threshold, you may register voluntarily to reclaim input VAT.

Who Must Register for VAT in Mauritius (Compulsory vs Voluntary)

Any person carrying on a business in Mauritius whose taxable supplies exceed the statutory threshold is required to apply for compulsory VAT registration in Mauritius. The obligation applies to companies, partnerships, sole traders and, since 1 January 2026, foreign suppliers of qualifying digital services. Two tests determine whether you have crossed the line: the look‑back test (taxable turnover in the preceding 12 months already exceeds the threshold) and the forward‑looking test (there are reasonable grounds to expect turnover will exceed the threshold in the next 12 months).

A practical illustration highlights the distinction. A sole trader whose cumulative invoices over the past year total MUR 2,800,000 is not yet compulsorily required to register. However, a newly formed company that has signed contracts projecting MUR 3,200,000 in its first year of trading is caught by the forward‑looking test and must apply before making its first taxable supply. In each case, failure to register on time exposes the business to penalties and back‑dated VAT assessments.

Current Thresholds and Timeline

Voluntary Registration, Pros and Cons

Businesses below the MUR 3,000,000 threshold may still opt for voluntary registration. The main advantage is the ability to reclaim input VAT on purchases, which is particularly valuable for start‑ups with heavy capital expenditure. The trade‑off is the compliance burden: you must charge VAT on all taxable supplies, file periodic MRA VAT returns, and maintain detailed records. Industry observers note that voluntary registration is most beneficial for B2B suppliers whose customers are themselves VAT‑registered, since those customers can claim input credits and are therefore indifferent to the VAT charge on invoices.

VAT Rates, Taxable Supplies and Exemptions

The standard VAT rate in Mauritius is 15 %, applied to most goods and services supplied in the country. Every VAT registered company in Mauritius must charge this rate on taxable supplies and account for it in periodic returns.

Exemptions and Zero‑Rating

Certain supplies are exempt from VAT, meaning no VAT is charged and no input credit may be claimed. Common categories subject to VAT exemption in Mauritius include financial services, residential rental income and selected educational and medical services. Zero‑rated supplies, by contrast, attract VAT at 0 % but still allow the supplier to reclaim input VAT, exports of goods are the most significant example. Understanding which category applies to your business is critical because it determines both whether you need to register and how to register for VAT correctly. The MRA publishes a detailed schedule of exempt and zero‑rated items, and businesses should consult it before applying.

Documents and Evidence You Must Prepare, VAT Registration Mauritius Requirements

Gathering the right documentation before you start the online application is the single most effective way to avoid processing delays. The MRA requires proof of identity, business existence, premises, turnover and banking details. The exact package depends on whether the applicant is a sole trader, a registered company, a foreign digital supplier or an agent filing under a Power of Attorney.

Power of Attorney and Agent Submission

Where a professional accountant or tax adviser submits the application on behalf of the business, the MRA requires a formal POA. The document must identify both parties, state the scope of authority (specifically VAT registration), and be signed by a director or the sole trader. Early indications suggest that incomplete or vaguely worded POAs are a frequent cause of application queries, so practitioners are advised to use clear, purpose‑specific language rather than generic authorisation clauses.

Evidence for Foreign Digital Suppliers

Since the 1 January 2026 extension, foreign suppliers of qualifying digital services must demonstrate that their customers are located in Mauritius. Acceptable evidence includes billing address details, IP geolocation data, bank or credit‑card country of issue, and platform‑level sales reports filtered by jurisdiction. Compiling this evidence before starting the registration process can materially reduce back‑and‑forth with the MRA.

Which Form to Use, VAT1 vs VAT1A (MRA VAT Forms Explained)

The MRA provides two principal forms for VAT registration. Understanding which to use is straightforward, but selecting the wrong one is a surprisingly common error that leads to unnecessary resubmissions.

• VAT1 (Standard Registration Form). Used for most businesses, companies, partnerships and sole traders applying through traditional channels or needing to provide detailed supplementary information not captured by the simplified form.
• VAT1A (Simplified Registration Form). Designed for use through the MRA e‑services portal. It captures essential fields, BRN, TAN, estimated annual turnover, nature of business activity, bank details, and is the form most applicants will complete when registering online.

Completing the VAT1A, Key Fields

When you open the VAT1A through the e‑services portal, pay close attention to the following fields:

1. BRN. Enter exactly as shown on your Business Registration Certificate. A single‑digit mismatch will trigger a system validation error.
2. TAN (Tax Account Number). This is your unique tax identifier issued by MRA. If you do not yet have a TAN, you must apply for one before starting VAT registration.
3. Estimated annual turnover. Base this on actual figures (look‑back test) or credible projections (forward‑looking test). Overstating or understating turnover can lead to queries.
4. Principal business activity. Use the MRA’s activity classification codes where prompted; free‑text descriptions alone may be rejected.
5. Bank details. A Mauritius‑based bank account is required. Provide account number, bank name and branch.

The likely practical effect of using VAT1A rather than VAT1 is a faster processing time, because the simplified form feeds directly into MRA’s automated validation system.

MRA E‑Services, How to Register for VAT Online in Mauritius (Step‑by‑Step)

Yes, you can complete VAT registration online in Mauritius through the MRA’s e‑services portal. The simplified VAT registration e‑service allows applicants to log in, complete the VAT1A, upload supporting documents and submit, all without visiting an MRA office. Below is the annotated process.

1. Prepare your documents. Assemble every item listed in the documents checklist above. Convert hard copies to clear PDF or JPEG scans; the portal imposes file‑size limits, so keep each file under 2 MB where possible.
2. Access the MRA Simplified VAT Registration e‑service. Navigate to the MRA website and select the Simplified VAT Registration option under VAT e‑services. You will be prompted to log in.
3. Log in using your credentials. The portal accepts three login identifiers, your National Identity Card (NID) number, your Business Registration Number (BRN) or your Tax Account Number (TAN). Choose the one that corresponds to the profile already registered with MRA. If you have never created an MRA online account, you will need to register for portal access first by following the on‑screen prompts.
4. Complete the VAT1A form. Fill in each field carefully, BRN, TAN, turnover estimate, business activity code, contact information and bank details. The system validates entries in real time; correct any flagged errors before proceeding.
5. Upload supporting documents. Attach scanned copies of your BRN certificate, NID or passport, lease agreement, bank details and turnover evidence. Label each upload clearly (e.g., “BRN_Certificate.pdf”).
6. Review and submit. The portal generates a summary screen. Verify every entry, then confirm submission. You will receive an electronic acknowledgement with a reference number, save this for follow‑up.
7. After submission. MRA reviews the application and supporting evidence. If everything is in order, a Certificate of Registration bearing your VAT number is issued. If additional information is needed, MRA will contact you via the email address on file. Respond promptly to avoid delays.

Login Options and Recovering Credentials

If you have forgotten your MRA e‑services password, use the “Forgot Password” link on the login page. You will need your NID or BRN to verify your identity. For TAN‑related login issues, contact MRA directly or visit a Taxpayer Service Centre with your original BRN certificate and NID.

Common Portal Errors and How to Fix Them

• BRN mismatch. The BRN entered on the form does not match MRA’s records. Solution: verify against your BRN certificate and re‑enter without spaces or dashes.
• File upload failure. Files exceeding the size limit or in unsupported formats are rejected. Solution: compress PDFs and convert images to JPEG before uploading.
• Session timeout. The portal may time out after a period of inactivity. Solution: prepare all information offline first, then complete the form in a single session.
• Duplicate application. Submitting a second application before the first is processed triggers a duplicate warning. Solution: use your reference number to check status instead of resubmitting.
• Missing TAN. The form will not proceed without a valid TAN. Solution: apply for a TAN through MRA’s e‑services before starting VAT registration.

After Registration, VAT Number, Invoices, Returns and Obligations

Once MRA approves your application, you receive a Certificate of Registration displaying your unique VAT registration number. From that date onward, every VAT registered company in Mauritius, or sole trader, must comply with invoicing, filing and payment obligations.

Your VAT invoices must show the supplier’s name, address and VAT number, the customer’s details, a description of the goods or services, the taxable value, the VAT amount (at 15 %) and the invoice date. Failure to issue compliant invoices is itself a penalty offence.

Filing VAT Returns, Self‑Filing vs Agent

VAT‑registered persons must file an MRA VAT return (Form VAT 3) for each taxable period and pay any VAT due by the prescribed deadline. Returns can be filed by the business owner directly through MRA e‑services or by an authorised agent. Self‑filing is straightforward for small operations with few transactions; larger or more complex businesses typically engage a professional accountant to ensure accuracy and timely submission.

How to Update Your Details

Changes in business address, ownership structure, bank details or trading name must be notified to MRA promptly. Updates can be submitted through the e‑services portal or in writing. Keeping records current avoids correspondence delays and ensures VAT certificates reflect accurate information.

Special Cases, New Businesses, Foreign Suppliers and Digital Services

Newly formed businesses face a unique challenge: they have no 12‑month look‑back data. In this situation, registration is triggered by the forward‑looking test, if projected turnover from signed contracts, order books or realistic business plans exceeds MUR 3,000,000, registration is compulsory before the first taxable supply is made. Industry observers expect MRA to scrutinise projections carefully, so maintaining supporting documentation (signed agreements, letters of intent) is essential.

Businesses with intermittent or seasonal supplies should aggregate turnover across the full 12‑month window rather than assessing individual months in isolation. A tourism operator earning most revenue between October and March, for example, must still consider the entire year.

The most significant recent change concerns foreign suppliers. From 1 January 2026, non‑resident providers of certain digital and electronic services to Mauritius‑based consumers are required to register for VAT. This applies regardless of whether the supplier has a physical presence in Mauritius. Affected suppliers include providers of streaming services, downloadable software, online advertising platforms, cloud‑based SaaS products and electronic marketplace facilitators. These businesses must register through MRA’s portal, appoint a local agent where necessary, and charge 15 % VAT on qualifying supplies.

Practical Checklist, How to Register for VAT and What to Expect After Submission

1. Confirm obligation. Determine whether you meet the compulsory threshold (MUR 3,000,000) or qualify under the digital services extension.
2. Obtain BRN and TAN. Ensure both are active and correctly recorded with MRA before starting the VAT application.
3. Gather documents. Use the entity‑specific checklist table above; scan all items as PDF/JPEG under 2 MB each.
4. Select the correct form. Use VAT1A for the online simplified route; VAT1 only if directed by MRA or if supplementary detail is needed.
5. Complete and submit via MRA e‑services. Log in with NID, BRN or TAN; fill in the form; upload documents; submit and save your reference number.
6. Monitor your application. Check email for MRA queries; respond within the timeframe indicated to avoid delays.
7. Receive your Certificate of Registration. Once issued, begin charging VAT, issuing compliant invoices and preparing for your first VAT 3 return.

Conclusion

Knowing how to register for VAT is the first compliance milestone for any business operating in Mauritius, and the process is now entirely achievable online through the MRA’s e‑services portal. With the threshold lowered to MUR 3,000,000 and VAT extended to digital services, more businesses than ever must act. Prepare your documents early, choose the correct MRA VAT form (VAT1A for the simplified online route), and submit a complete application to minimise processing time. Once registered, stay on top of invoicing rules, MRA VAT return deadlines and recordkeeping obligations to remain fully compliant. For businesses navigating complex structures, cross‑border digital supplies or first‑time registration, professional accounting and tax advisory support can be invaluable.
