How to Register as an Employer with MRA Mauritius (2026 Guide)

Before you can interact with the MRA, your business must have a legal identity. For companies, this means incorporation under the Companies Act 2001. For sole traders, this involves registering a business name. Both paths result in the issuance of a Business Registration Number (BRN) from the Corporate and Business Registration Department (CBRD).

In 2026, the CBRD and MRA systems are highly integrated. When a new entity is registered, the Central Business Registration Information System (CBRIS) automatically notifies the MRA. However, receiving a Tax Account Number (TAN) does not automatically mean you are 'active' as an employer. You must specifically activate your status for PAYE and social security contributions once you hire your first staff member. Payroll.mu frequently assists new startups in navigating this 'pre-payroll' phase to ensure the MRA records match the actual start date of employment.

Every employer in Mauritius is required to register for the PAYE system if they pay emoluments to employees above the prescribed threshold. PAYE is the mechanism where the employer withholds income tax from employees' salaries and remits it to the MRA.

To register, navigate to the MRA e-Services portal. You will need your TAN and your MRA credentials (usually sent to your registered business address). Under the 'Registration' tab, you can select 'Employer Registration'. You will be required to provide details such as the estimated number of employees, the nature of the business, and the effective date from which you started paying salaries. It is vital to note that even if an employee's salary is below the tax threshold, you must still register to fulfill social security obligations.

While 'Social Security' used to be a separate department, all contributions in Mauritius are now centralized under the MRA. This includes the Contribution Sociale Généralisée (CSG) and the Portable Retirement Gratuity Fund (PRGF).

As of 2026, there is no 'separate' social security form. Instead, when you register as an employer for PAYE, you are effectively entering the system to pay CSG and PRGF. The CSG is mandatory for all employees (local and expatriates), with rates typically varying based on whether the monthly salary is below or above MUR 50,000 (subject to 2026 budget adjustments). The PRGF is specifically for the benefit of employees who are not covered by a private pension scheme. Using a local solution like Payroll.mu ensures these percentages are automatically calculated based on the latest MRA regulations.

Once registered, your primary legal obligation is the monthly e-Filing. The deadline for filing the 'Monthly Return of Employees' and making the relevant payments is generally the end of the month following the month in which the salaries were paid. For example, July's payroll must be filed by August 31st.

Each month, your return must include:

1. Employee details (NID/Passport numbers)
2. Gross salary and taxable fringes
3. Amount of PAYE deducted (if any)
4. CSG contributions (Employer and Employee shares)
5. PRGF contributions
6. National Savings Fund (NSF) and HRDC Training Levy (typically 1.5% and 1% respectively)

Accuracy is critical. Errors in NID numbers or salary reporting can lead to MRA queries and penalties. Many Mauritius businesses outsource this to Anexa.mu to safeguard against submission errors.

In addition to monthly filings, employers must provide each employee with an 'Employee Declaration Form' (EDF) at the start of the financial year. This allows employees to claim exemptions and reliefs, which determines how much PAYE you should deduct.

Furthermore, at the end of the financial year (June 30th), employers must issue a Statement of Emoluments to every employee and file an Annual Return with the MRA. This annual return reconciles all the monthly payments made throughout the year. Failure to provide a Statement of Emoluments to an employee is an offense under the Income Tax Act. For companies managing dozens of employees, HR software like QuickFocus.biz can automate the generation of these certificates at the click of a button.

Mauritius is strict regarding payroll compliance. The MRA regularly conducts audits to ensure that the classification of workers (employee vs. independent contractor) is correct and that all fringe benefits (cars, housing, etc.) are being taxed appropriately.

If your business is growing, manual spreadsheets are no longer a viable option due to the complexity of the PRGF and the shifting tax brackets in 2026. Partnering with a professional firm like Anexa ensures that your employer registration is not just a one-time setup but a continuous path of compliance. Whether it's managing the HRDC refund process or ensuring your expatriate staff have the correct Work Permit-linked tax profiles, expert guidance is invaluable.
