Running Monthly Payroll Step by Step

If you are asking how to run payroll in Mauritius, the short answer is that it is a cycle, not a single task. The same sequence repeats every month: collect the variable data, calculate gross pay, apply statutory deductions, check the result, pay staff, issue payslips, file the returns and archive the evidence. Once the cycle is fixed, each month takes much less effort than the first.

This page walks through that payroll process in Mauritius in the order a payroll officer would follow it. It does not replace the detailed rules, which sit on the dedicated pages for each levy, and it gives no figures that depend on the current rates. For the wider picture of what an employer owes, start with payroll in Mauritius.

The monthly cycle at a glance

Before the first cycle: set the foundations

A smooth monthly run depends on a few decisions taken once.

• Employer registration. You must be registered with the tax authority as an employer before you pay anyone. The steps are on the page about registering as an employer before hiring.
• Employment contracts. Every employee should have a written contract stating pay, allowances, working time and notice, because payroll can only apply what the contract and the law say.
• A payroll calendar. Fix a cut-off date for inputs, a review date, a payment date and a filing date. Share it with managers so that late changes are the exception.
• A master file per employee. Keep identity details, tax and contribution references, bank details and contract terms in one place, and change them only on a documented instruction.

Step one: collect and freeze the variable data

Fixed salaries rarely change, but the rest does. Before each run, gather:

• hours worked, absences and approved overtime, where the contract or the applicable wages regulations provide for it;
• leave taken during the period, including unpaid leave;
• new joiners, with their start date, and leavers, with their last day;
• one-off items such as commissions, expense reimbursements, a bonus or an advance to recover.

Set a cut-off and stick to it. A change received after the cut-off goes into the next month, unless it corrects an error. This single habit prevents most reruns. Make sure the timesheet approver is a manager, not the payroll officer, so that the person who calculates pay is not the person who validates hours.

If you employ people in a sector with a specific wages order, check it before you set up overtime and allowance rules; the page on wages regulations and employer obligations explains where to look.

Step two: compute gross pay

Gross pay is everything the employee earns before deductions. Build it line by line:

1. basic salary for the period, adjusted for part-month joiners and leavers;
2. fixed allowances written into the contract;
3. overtime and other variable pay;
4. any bonus due this month, including the year-end bonus where it applies, which is covered under the 13th month bonus in payroll;
5. benefits in kind, which usually need a taxable value assigned to them.

Keep each component on its own line in the payroll system or spreadsheet. A single "total pay" figure makes errors impossible to trace and makes the payslip harder to explain.

Step three: apply statutory and other deductions

From gross pay you compute what is withheld. Three items concern almost every employer:

• Income tax at source. Employers withhold tax on employment income under the PAYE system and remit it to the tax authority. See PAYE in Mauritius for employers.
• Contribution Sociale Généralisée. Both employer and employee contribute, and the rate depends on the employee's pay. Details are on CSG contributions for employers and employees.
• National Savings Fund. A further contribution is linked to a payroll return; read NSF contributions and payroll returns.

Rates and thresholds are revised from time to time, so take them from the official source on the day you run payroll rather than from an old spreadsheet. If you want to test your calculation, the walkthrough on calculating net pay in Mauritius shows how the lines connect.

Other deductions, such as a recovered advance or a loan repayment, should rest on a written authorisation from the employee or on a legal basis. Never deduct something simply because the employee agreed verbally. Which deductions are lawful, and in what order, can depend on the employee's situation; ask an adviser when in doubt.

Step four: review before you pay

Review is the cheapest control you have. Before approving the run:

• compare each employee's net pay with last month and investigate any movement beyond what you expected;
• check that leavers have been paid their final amounts and removed from the next run;
• check that no joiner is missing and that no one appears twice;
• reconcile total gross pay to the payroll journal that will go to bookkeeping;
• confirm that someone other than the preparer signs off.

A short exception report, listing only the people whose pay changed and why, is easier to review than the full register and catches most mistakes.

Step five: pay your employees and issue payslips

Once approved, transfer net pay using the bank details on the master file, and keep the bank confirmation with the payroll papers. Pay by the date set in the contract or applicable rules, so the cut-off and review dates should be set early enough to make that date comfortable.

Payslips are not a courtesy. Each employee should receive a clear statement for the period showing what was earned, what was deducted and what was paid. The exact content is set by law, and the page on what a payslip must contain lists it. As a practical matter, a good payslip shows:

Deliver payslips through a channel that is secure and traceable. Sending them as unprotected attachments to a shared mailbox is a common cause of data leaks.

Step six: file the returns and remit the amounts

After payment comes the compliance side. Each employer obligation has its own return, its own channel and its own statutory deadline. In practice you will:

• submit the PAYE, CSG and NSF information through the tax authority's online channel;
• remit the amounts withheld and the employer's own contributions by the due date;
• reconcile the amounts remitted with the payroll journal.

A late return can be penalised, so the filing date in your payroll calendar should sit comfortably before the legal deadline. If you are new to the online portal, the online filing walkthrough is a useful companion. Penalties and their consequences are discussed generally on the page about penalties for non-compliance.

Step seven: record, reconcile and archive

The last step is the one most often skipped. For each month, store:

• the approved payroll register and the exception report;
• the payslips as issued;
• the bank confirmation and the filed returns with their acknowledgements;
• the input documents: approved timesheets, leave forms and any authorisation for a deduction.

Post the payroll journal to your books so that salary cost, withheld taxes and contributions payable appear correctly. How long to keep each category is explained on the page about company records. Year-end work, such as employee tax summaries, builds directly on these monthly files.

Protecting employee data in the payroll process

Payroll holds some of the most sensitive data a company has: identity numbers, bank accounts, family situation and sometimes health-related absences. Under the Data Protection Act 2017, a company that decides how that data is used acts as a controller, and a payroll bureau acting on its behalf is a processor. Controllers and processors register with the Data Protection Commissioner, and the registration certificate is valid for 3 years (section 16(3) of the Data Protection Act 2017).

The registration or renewal fee depends on headcount. Under the Data Protection (Fees) Regulations 2020, in force since 1 August 2020, it is Rs 1 000 for up to 5 employees, Rs 1 500 for 6 to 25 employees and Rs 2 500 for more than 25 employees.

If payroll is processed outside Mauritius, for example by a group function abroad, section 36 of the Data Protection Act 2017 lets a controller or processor transfer personal data out of the country in certain cases, including where it has given the Commissioner proof of appropriate safeguards, or where the data subject has given explicit consent after being informed of the risks. Which route suits your set-up is a legal question for an adviser.

A monthly payroll checklist

Use this list at every cycle and keep a signed copy with the payroll papers.

• Inputs frozen at the cut-off date and approved by the line manager
• Joiners, leavers and changes of contract applied
• Gross pay computed with each component on its own line
• PAYE, CSG and NSF calculated with the rates currently published
• Authorised deductions supported by a written document
• Variance report reviewed and signed by a second person
• Net pay transferred and the bank confirmation saved
• Payslips issued securely to every employee
• Returns filed and amounts remitted before the legal deadline
• Payroll journal posted to the books
• Records archived and access restricted

Common mistakes to avoid

• Leaving the cut-off to chance. Accepting changes up to the last minute is the main cause of rerun payroll and corrected payslips.
• One person doing everything. When the same person enters, calculates, approves and pays, a mistake or fraud can go unseen.
• Using last year's rates. Rates and thresholds change; check the official source each cycle.
• Treating a contractor as an employee, or the reverse. The classification affects what you must withhold. If the position is unclear, take advice before the first payment.
• Forgetting leavers. A departure that is not recorded can mean pay going out after the last day.
• Weak document storage. Payroll files should not sit in a shared folder open to the whole team.

If you outsource the work, the cycle does not disappear; you still approve the inputs and the output. The page on choosing a corporate services provider helps you assess who should handle it.
