For many entrepreneurs in Mauritius, the first VAT Return is a source of real stress. The MRA form looks intimidating, the fields seem obscure, and the fear of making a mistake leads to procrastination — which only makes things worse. This guide demystifies the VAT return from start to finish: filing frequency, form fields, mistakes to avoid, and what to do if you miss the deadline.
👉 The deadline you must never miss: the 20th of the following month after the period ends. For January, the return and payment are due by 20 February — no exceptions. Any late submission automatically triggers a penalty of Rs 2,000 per month plus 1% interest on the amount owed.
Monthly or Quarterly: Who Decides, and Can It Change?
The MRA sets your filing frequency at the time of registration, based on your estimated turnover.
Assigned to businesses with turnover exceeding Rs 10 million per year. Return due by the 20th of each month for the previous period. Advantage: you track your VAT position in real time and avoid unpleasant surprises.
For businesses between Rs 3M and Rs 10M annual turnover, return due by the 20th of the month after each quarter periods (January–March, April–June, July–September, October–December). Less admin, but watch out for cumulative amounts (if you miss the date, you pay at least Rs 2000).
👉 Can you request a change of frequency? Yes. If your situation changes significantly (strong growth or a drop in activity), you can submit a written request to the MRA. The change takes effect at the start of the next period. Conversely, if your turnover crosses the Rs 10M threshold, the MRA may switch you to monthly filing on its own initiative.
The 5 Key Fields of the VAT Return Form
The MRA form may look daunting at first glance. In practice, it comes down to 5 main sections:
Output Tax (VAT charged)
Total VAT you have charged your clients during the period. Add up the VAT from all your sales invoices subject to 15%.
Input Tax (deductible VAT)
VAT you have paid on your business purchases (supplies, equipment, services…). Only expenses related to your taxable activity are deductible.
Net VAT payable (balance due)
The result of A – B. If positive, this is the amount you owe the MRA. If negative, you have a VAT credit.
Zero-rated supplies
The ex-VAT amount of your sales invoiced at 0% (clients outside Mauritius, exports). These amounts do not enter the output tax calculation but must be declared.
Exempt supplies
The ex-VAT amount of your VAT-exempt sales (education, healthcare…). Like zero-rated sales, these are declared but not taxed.
Pre-Submission Checklist
- All sales invoices for the period have been recorded
- All purchase invoices (deductible VAT) have been entered
- Credit notes have been accounted for
- Zero-rated sales are separated from 15% taxable sales
- Exempt supplies have been identified and isolated
- The VAT balance (output − input) has been calculated and checked
- Payment is ready if the balance is positive
- No personal expenses are included in deductible VAT
VAT Credit: Refund or Carry Forward?
If your input tax exceeds your output tax — which often happens for freelancers who invoice many foreign clients at zero-rate — you have two options.
- Carry forward to the next period: the credit is automatically deducted from your next return. This is the simplest option if your activity is regular.
- Refund request to the MRA: submit a formal request via MRA e-Services. The standard processing time is 60 to 90 days. The MRA may ask for supporting documents before issuing the refund.
👉 Tip: if your VAT credit is recurring and significant, claiming a refund is better than carrying it forward — letting a credit accumulate over several periods without recovering it means unnecessarily tying up cash.
The 4 Most Common Mistakes
Invoicing a foreign client at 0% VAT does not mean ignoring those sales in your return. They must appear in Box D of the form. Their absence can trigger an MRA review of the consistency of your declared turnover figures.
The VAT Return form requires ex-VAT amounts everywhere, except for the VAT itself. Entering inc-VAT figures artificially inflates your base and creates a discrepancy that the MRA will detect when cross-referencing your invoices.
A credit note cancels or reduces an invoice. If you issue a credit note in January but forget it in your January return, you declare more output tax than you actually collected — you overpay, and the correction after the fact is cumbersome.
VAT on a personal meal, a non-business purchase, or a mixed-use expense (a car also used privately) is not fully deductible. Claiming these amounts without justification is one of the most frequent triggers for reassessment during an audit.
Missed the Deadline: What Now?
If you missed the 20th, act immediately — every additional day makes things worse. Log in to MRA e-Services, submit your late return and pay the amount due along with the applicable penalties. Hoping it goes unnoticed is the worst strategy: the MRA automatically cross-references data and follows up with non-compliant taxpayers.
A voluntary late filing — even with penalties — is always preferable to a forced reassessment following an audit, which can result in adjustments covering previous periods as well.
