13th Month Salary Mauritius: 2026 Guide for Employers

The most common mistake Mauritian employers make is assuming the bonus is only for those who completed the full calendar year. Under the Workers' Rights Act 2019, any employee who has been in continuous employment for at least one month (30 days) is entitled to a pro-rata bonus. This applies even if the employee resigned, was made redundant, or retired before December.

Crucially, the bonus is equivalent to 1/12th of the earnings the employee received during that calendar year. If an employee started on July 1st, they are entitled to 50% of a full month's salary. At Anexa.mu, we often see businesses forgetting to account for employees who left in the first quarter of the year, leading to unexpected claims later on.

The 'last month's salary' rule is the standard for employees who have been present throughout the year. If an employee is still in service in December, their bonus should generally be equivalent to their December basic salary. However, if the employee's salary fluctuated due to commissions or piece-work, the law requires a calculation based on 1/12th of total earnings.

Employers often forget that 'earnings' include the basic wage plus any productivity bonuses or other allowances that are deemed part of the remuneration under the specific Remuneration Order applicable to their industry. Using a local solution like Payroll.mu ensures that these specific industry-based Remuneration Orders are automatically applied to your monthly runs.

The law is very specific about the 'When.' The 13th-month salary must be paid no later than the last working day preceding the 25th of December. If an employee's contract is terminated before the end of the year, the pro-rata bonus must be paid at the time of the final settlement (typically within 7 days of the last working day).

Delaying this payment is a breach of the Workers' Rights Act. The Ministry of Labour regularly conducts audits in January to ensure compliance. Businesses using QuickFocus.biz for their accounting and payroll usually schedule these payments early in December to avoid bank bottlenecks and ensure peace of mind.

One of the most complex areas of Mauritian payroll involves sick leave and its impact on the end-of-year bonus. Legally, days taken as statutory sick leave, injury leave, or maternity leave are counted as 'days worked' for the purpose of calculating the 13th-month salary. Employers cannot deduct these days from the bonus calculation.

However, if an employee has taken unauthorized leaves or unpaid leaves beyond their statutory entitlement, the employer may adjust the bonus pro-rata. This requires meticulous record-keeping. Our team at Solution.mu recommends integrating your biometric attendance system directly with your payroll to avoid manual errors in these calculations.

In Mauritius, the 13th-month bonus is subject to Income Tax (PAYE) if the total yearly income exceeds the tax-free threshold. However, for many years, the government has provided specific exemptions or thresholds for bonus taxation to provide relief to workers. As of 2026, it is vital to check the latest MRA Budget circulars.

It is a common misconception that the bonus is 'tax-free' for everyone. Employers must accurately compute the cumulative yearly tax to determine if PAYE should be withheld from the December bonus. Failing to withhold correctly can result in the employer being held liable for the tax shortfall during an MRA audit. Anexa.mu provides specialized tax consultancy to help businesses structure their year-end rewards efficiently.

While the 13th-month salary is the legal minimum, many Mauritian companies offer a '14th month' or performance-based bonuses. It is vital to distinguish these in the payslip. The 13th month should be labeled clearly as 'End of Year Bonus' to satisfy labor inspectors.

Any additional bonus should be governed by a clear Performance Bonus Policy. Without a written policy, an additional bonus paid for three consecutive years might be considered an 'acquired right' (droit acquis) by the Industrial Court, making it mandatory in future years even if company performance dips. Always consult with a professional payroll service like Payroll.mu before establishing recurring bonus patterns.
