13th Month Bonus in Payroll

The end of year bonus in Mauritius is a yearly payment that most employees receive in addition to their normal pay. In everyday speech it is the "13th month salary", although the legal name and the way it is worked out matter more than the label. For a company with staff, it is a predictable cash outflow and a payroll event with tax and contribution consequences.

This page follows the bonus through the payroll: what it is, how it reaches the employee, how it is taxed, and how it feeds into social contributions. It does not repeat the wider rules on pay and working conditions, which are covered in wages regulations and employer obligations.

What the end of year bonus is

In Mauritius the bonus is not a gift and not a matter of company custom alone. It is an entitlement set by employment legislation and the regulations that apply to the employee's sector. Its precise basis therefore depends on the contract, the sector and the legislation in force at the time of payment.

Three points are worth keeping in mind:

• It is distinct from a performance bonus. A discretionary reward for results is a separate item, even if both are paid in the same month.
• It can be improved by contract. A contract, a collective agreement or an established practice may give the employee more than the legal minimum. The minimum cannot be reduced by contract.
• Sector rules can differ. Some sectors follow their own remuneration regulations. Check the rules that cover your employees before fixing the amount.

The exact formula, the statutory payment date and any thresholds are set by the legislation and change from time to time. This page deliberately gives no figure for them; confirm the current rule with your adviser or the competent authority before you budget.

Who is entitled to it

As a rule, an employee who has worked during the year is entitled to the bonus, in proportion to the period of service. The questions that come up most often are these:

• Part-year employees. Someone who joined during the year normally receives a bonus calculated on the period actually worked.
• Leavers. An employee who leaves before year end is generally entitled to a pro rata amount, payable on departure or at the usual time depending on the rule that applies.
• Part-time and fixed-term staff. They are not excluded by that status alone; the bonus follows the pay actually earned.
• Directors. An executive director who is on the payroll is treated like an employee for payroll purposes, but a director paid by fee is a different case. How that payment should be structured is explained in paying a director properly.

A company with a single director and no other staff may have no bonus obligation at all. That is a common situation for a small private company with one director, and it is worth confirming before the year end rather than assuming.

How the bonus is calculated and paid

The bonus is based on the remuneration earned during the year, and the regulations define which components count. Whether overtime, commission or allowances are included is a question of the definition in force, not of what the company decides.

In practice, payroll teams follow a simple sequence:

Pay the bonus through the payroll system, not outside it. A payment made in cash or by a separate transfer without a payslip leaves the employer with no record of the tax and contributions, and the employee with no proof of income. The rules on what the slip must show are set out in what a payslip must contain.

The payment deadline

The legislation sets a date by which the bonus must be paid. Missing it exposes the employer to a claim by the employee and to enforcement action. Build the date into your yearly planning, alongside the other fixed dates in the compliance calendar.

How the bonus is taxed

The bonus is employment income. It is added to the employee's other remuneration and is subject to PAYE through the employer. There is no separate bonus tax regime that applies by itself, and the employer withholds the tax in the same way as for salary.

Two practical consequences follow:

• The tax effect depends on the employee. The amount withheld on the bonus depends on the employee's overall income and the method of calculating PAYE in force, so two employees receiving the same bonus can see different deductions.
• The employer's job is to withhold and report. The employee's final position is settled through the income tax return where one is due.

For the withholding mechanics, see PAYE in Mauritius for employers. For how the different deductions compare, see payroll taxes in Mauritius compared.

Contributions on the bonus

The bonus is generally part of the remuneration on which social contributions are computed. Two contributions deserve attention:

• CSG. The employer and the employee each contribute on remuneration, and a bonus paid in a month increases the base for that month. See CSG contributions for employers and employees.
• NSF. Contributions are linked to monthly remuneration and may be subject to a ceiling. A large bonus in one month can therefore have a different effect from the same amount spread over the year. See NSF contributions and payroll returns.

The training levy and other employer charges can also be linked to remuneration. The treatment of the HRDC levy is covered in the training levy paid to the HRDC.

Summary table

Accounting and cash planning

The bonus is a cost of the year in which the service is rendered, even if it is paid shortly after the year end. Where the financial year ends before the payment date, the amount is normally recognised as a liability in the accounts. This is an accounting point for your preparer of financial statements; see preparing annual financial statements for the wider process.

On the cash side, plan for the bonus together with the tax and contributions that fall due on it. Many employers set aside a monthly provision rather than absorb the full cost in a single month. Quarterly management accounts are a convenient place to track that provision.

Common mistakes

• Treating the bonus as optional when the employee has a statutory entitlement.
• Paying it outside the payroll, so tax and contributions are not declared.
• Forgetting the pro rata amount owed to leavers.
• Applying the wrong definition of remuneration, which gives a bonus that is too high or too low.
• Missing the payment date because it was not entered in the yearly planner.
