Overtime Calculation Mauritius: 2026 Employer Guide

The cornerstone of all overtime calculations in Mauritius is the Workers' Rights Act (WRA) 2019. As of 2026, the law remains clear: a standard work week consists of 45 hours of work. This is typically structured as five days of nine hours or six days of alternating lengths, excluding meal breaks.

Any work performed in excess of those 45 hours constitutes overtime. Additionally, for employees working a five-day week, any work performed on the sixth day (the typical Saturday) is treated as overtime, provided the 45-hour threshold has been reached. It is important to note that the WRA 2019 protects employees from being forced to work overtime without reasonable notice, and remuneration must be paid no later than the next pay cycle. Failure to calculate this correctly can lead to disputes with the Ministry of Labour and potential Industrial Court cases.

To calculate overtime accurately, you must first determine the employee's 'Hourly Rate'. In Mauritius, this is generally calculated by dividing the monthly basic salary by the number of hours in a month. For a standard 45-hour week, the industry standard divisor is 195 hours (45 hours x 52 weeks / 12 months).

For example, if an employee earns MUR 30,000 per month:

• Basic Hourly Rate = MUR 30,000 / 195 = MUR 153.85 per hour.

Once the hourly rate is established, you apply the prescribed multipliers:

1. 1.5x Rate: Applied for hours worked beyond 45 hours on a normal working day or on a Saturday (for 5-day week workers).
2. 2.0x (Double) Rate: Applied for any work performed on a Sunday or a Public Holiday.

Using our example, an hour of overtime on a Monday would cost MUR 230.77 (153.85 x 1.5), while an hour on a Sunday would cost MUR 307.70 (153.85 x 2).

Work on Sundays and Public Holidays in Mauritius carries a specific premium. Regardless of whether the employee has already completed 45 hours during the week, work on these days is inherently 'overtime' in nature. Under the WRA 2019, if an employee works on a public holiday, they are entitled to a full day's pay plus an additional amount calculated at double rate for every hour worked.

For businesses in the hospitality or retail sectors that operate on 'staggered' rosters, the rules can be more complex. However, the principle remains that total weekly hours exceeding 45 must be compensated. If a Public Holiday falls on a day the employee is already scheduled to work as part of their 45 hours, the 2x rate still applies to the hours worked that day. This is a common area of confusion where Payroll.mu provides essential automated logic to prevent over or under-payment.

Overtime is not just an expense; it is taxable income. In the 2025/2026 tax environment, all overtime earnings must be included in the 'Gross Pay' for the calculation of Contribution Sociale Généralisée (CSG) and the Revenue Reserve Fund (PRGF).

From a PAYE (Pay As You Earn) perspective, overtime is added to the basic salary and other allowances. Since Mauritius moved to a progressive tax system (0% to 20%), high amounts of overtime can push an employee into a higher tax bracket for that specific month. Employers are responsible for accurately deducting the correct tax amount and submitting the Monthly Return via the MRA e-Filing portal. With Anexa’s accounting integration, these figures flow directly from payroll to your financial statements, ensuring the MRA Statement of Assets and Liabilities always balances.

Manual calculation of overtime via Excel is the leading cause of labor disputes in Mauritius. Common errors include using the wrong divisor (e.g., using 160 hours instead of 195), forgetting to include fixed allowances in the 'basic' calculation for certain Remuneration Orders, or failing to track 'Time Off in Lieu' (TOIL) correctly.

By using a localized solution like Payroll.mu, these variables are pre-configured. Our software understands the 2019 Workers' Rights Act by default. It allows for digital time-and-attendance integration, meaning hours are pulled directly from biometric scanners or mobile clock-ins, calculated against the 45-hour threshold, and pushed to the payslip with the correct 1.5x or 2x multipliers automatically. This level of automation is no longer a luxury in 2026; it is a necessity for risk management.
