Tax and compliance basics every small business owner should know in Mauritius

Starting a small business in Mauritius is an exciting step, but it also comes with legal responsibilities that every entrepreneur must understand and manage. Complying with tax obligations and regulatory requirements set by the Mauritius Revenue Authority (MRA) is not optional - it’s fundamental to operating legally and sustainably.

📑Register for tax with the MRA

Every business operating in Mauritius must be registered with the Mauritius Revenue Authority (MRA) for tax purposes. This includes obtaining a Tax Account Number (TAN) for filing returns and payments.

For electronic filing and payments, the MRA’s e-Services platform allows businesses to submit their income tax, VAT and other returns online:

💰Understand income tax requirements

For self-employed individuals (sole traders)

Self-employed persons must file an annual income tax return declaring business income from the year ended 30 June. Depending on your revenue and income, you may choose to file a standard, simplified, or presumptive return via MRA e-services.

If your gross business income exceeds certain thresholds, you may also need to submit quarterly statements under the Current Payment System (CPS).

For incorporated companies

Companies - even in their first year -  must file a Corporate Income Tax Return with the MRA, typically within six months of the financial year-end. Corporate tax in Mauritius is generally assessed at 15%, with certain incentives or exemptions available depending on activity.

Official guiding documents and forms can be found on the MRA business and corporate taxation pages:

🏷️ Value Added Tax (VAT) compliance

VAT is a tax on goods and services supplied in Mauritius. The standard rate is 15%.

When must you register?

From 1 October 2025, compulsory VAT registration applies to businesses whose annual taxable supplies exceed MUR 3 million down from the previous threshold of MUR 6 million.

Once registered, you must:

✔ Charge VAT on taxable sales
✔ Issue VAT-compliant invoices
✔ Submit VAT returns electronically (usually quarterly or monthly)
✔ File and pay on time to avoid penalties

👥 Payroll and employer responsibilities

If you employ staff, the MRA automatically registers your business as an employer for PAYE and social contributions when you indicate this during business registration or via your first employee return.

📍As an employer, you are responsible for:

✔ Withholding PAYE (Pay As You Earn) tax from employees
✔ Submitting monthly PAYE and social contributions returns
✔ Issuing year-end employee income statements

These obligations are submitted electronically using your employer registration number (ERN).

📂 Keep accurate records

Good record-keeping is the foundation of tax compliance. You should consistently maintain:

✔ Sales and purchase invoices
✔ Bank statements
✔ Payroll records
✔ Expense receipts
✔ VAT and income tax filings

Accurate documentation makes it easier to complete returns, claim deductions, and respond to any audit or inquiry from the MRA. It also increases your credibility when applying for financing such as SME loans or working capital solutions with MCB.

Maintaining separate business banking records helps simplify all tax reporting.

📅 Meet deadlines

Tax deadlines are strict. Key points include:

✔ Income tax returns for individuals and companies are due annually, based on the year ending 30 June.
✔ VAT returns are usually quarterly or monthly once registered.
✔ PAYE and social contributions returns are monthly for employers.

Missing deadlines can result in penalties and interest charges, so maintain a compliance calendar to track filings.

🤝 7️⃣ Seek advice to stay compliant

Mauritian tax law includes specific nuances — for example, changes to VAT thresholds and employer reporting requirements. When in doubt, consult with a qualified accountant or tax adviser to ensure accurate compliance and planning.
