CSG Mauritius Explained: 2026 Employer & Employee Guide

As of 2026, the CSG structure remains a progressive system designed to provide more support to lower-income earners while ensuring the sustainability of the National Pension Scheme. The contribution is split between the employer and the employee. For employees earning up to MUR 50,000 per month, the employee contribution is 1.5% of the basic wage, while the employer contributes 3%. For those earning above the MUR 50,000 threshold, the rates increase to 3% for the employee and 6% for the employer.

It is important to note that these rates apply to the 'Basic Wage.' Under the Workers' Rights Act 2019, the basic wage is the reward in money paid to an employee for work performed under their contract. Business owners must ensure that their payroll software, such as the solutions provided by Payroll.mu, correctly categorizes allowances and overtime to avoid overpayment or under-contribution. For domestic workers, specific flat rates or simplified tiers may apply, which are updated annually by the MRA.

Compliance is managed through the MRA e-Filing system. Employers are required to submit their CSG returns monthly, alongside PAYE (Pay As You Earn) and PRGF (Portable Gratuity Fund) contributions. The deadline for submission and payment is typically the end of the month following the month in which the salaries were paid. For example, July salary contributions must be remitted by the 31st of August.

Failure to comply with these deadlines results in a 5% penalty on the amount due and an additional interest of 1% per month for as long as the amount remains unpaid. Using a localized payroll service like Anexa.mu or the Payroll.mu platform automates these filings, generating the necessary XML files or CSV exports required for seamless MRA upload. This reduces the risk of manual data entry errors which are common in manual accounting processes.

One common point of confusion for HR managers is the distinction between CSG and PRGF. While CSG is a social contribution for immediate and future social security (like the basic retirement pension), the PRGF is a fund designed to ensure that most employees receive a gratuity upon retirement or death, regardless of the number of employers they have worked for during their career.

Unlike CSG, which is shared, the PRGF is exclusively an employer's liability (at a rate of 4.5% of the basic wage, subject to exemptions for companies with private pension schemes). In 2026, the MRA requires both to be reported on the same Joint Monthly Return. At QuickFocus.biz and Solution.mu, we advise our clients to treat these as two distinct financial liabilities that must be accrued monthly to maintain a healthy balance sheet.

Self-employed individuals in Mauritius are not exempt from the Contribution Sociale Généralisée. Whether you are a consultant, a freelancer, or a small shop owner, you are mandated to contribute based on your net income. The MRA has streamlined this process by allowing self-employed persons to pay their CSG on a monthly or quarterly basis.

In 2026, the income brackets for the self-employed are regularly reviewed. Generally, if a self-employed person's income falls below a certain threshold, they may pay a minimum prescribed fee. However, once the income exceeds the standard threshold (matching the private sector), the percentage-based system kicks in. Ensuring accurate bookkeeping is essential here, as the MRA may audit net income declarations to verify CSG accuracy. This is where Anexa.mu’s accounting services provide significant value to local entrepreneurs.

Since its inception, the CSG has been the subject of various legal challenges and policy debates. However, as of 2026, it remains the settled law of the land. The funds collected via CSG are utilized by the Ministry of Social Security to pay the Basic Retirement Pension (BRP) to citizens aged 60 and above.

Businesses should also stay aware of the 'CSG Income Allowance.' In recent years, the government has used the CSG framework to distribute direct income support to employees earning below a certain level. While this isn't a direct cost to the employer, the payroll department must ensure that employee details (like bank accounts and NID numbers) are updated in the MRA system to facilitate these direct government-to-citizen transfers.

The complexity of Mauritian payroll—comprising CSG, PRGF, PAYE, NSF, and the Levy—makes manual calculation risky. Modern businesses in Mauritius are shifting toward cloud-based automation. A localized payroll system ensures:

1. Automatic updates to tax and CSG slabs as per the National Budget.
2. Direct generation of the MRA Joint Monthly Return.
3. Accurate computation of the 'Basic Wage' vs 'Gross Salary' for contribution purposes.
4. Compliance with the latest Workers' Rights Act amendments.

By partnering with Payroll.mu or Anexa.mu, businesses can redirect their focus from administrative paperwork to strategic growth, knowing that their social contributions are calculated to the cent and submitted on time.
