CSG / Social Contributions return for Employer / Employee

Following changes brought by the Finance (Miscellaneous Provisions) Act 2020, the Contribution Sociale Généralisée (CSG), has been introduced and is applicable as from the month of September 2020. Every employer is required to submit, electronically, a monthly contribution return on a monthly basis giving the details of each employee, the CSG, NSF and Training Levy applicable and at the same time electronically pay the contributions payable to the MRA. A self-employed is required to pay CSG at an amount of 150 rupees per month. This new system of social contributions replaces the National Pensions Fund (NPF) and the last month in respect of which contributions to the National Pensions Fund was applicable is August 2020. With a view to facilitate employers, the MRA has put in place a system for e-Filing of a monthly PAYE/CSG/NSF return. Employers are required to use the new templates as from the pay period of September 2020.

As from September 2021 under The Social Contribution and Social Benefits Act 2021, social contributions shall apply on end of year bonus prescribed under an enactment. The social contributions payable on end of year bonus shall be computed separately from the contributions payable on the monthly basic wage/salary. The social contribution on end of year bonus shall be calculated on the basic wage/salary component only (excluding any allowance, commission, productivity payment etc).

Where in a calendar year an employer effects payment of the statutory end of year bonus in more than one month, the social contribution rate applicable in each month shall be determined by cumulating the amount of end of year bonus paid in the respective month.

To avail of this facility, employers are requested to use their Employer Registration Number (ERN) as User ID and the password allocated by the MRA. Two options are available for the submission of the return; either using "SCREEN INPUT" or a CSV file as per MRA’s specifications given below. Employers having opted to input employee details one by one will have to select "SCREEN INPUT", after login.

However, a self-employed is required to use his National Identity Card Number (NID)/ Non- Citizen Identity Card Number (NCID) for Login. A one-time password (OTP) will be sent to the mobile number provided by you at the time of Login.

Employers should include the details of ALL their employees in the return.

The minimum and maximum basic wage or salary on which Contributions to the National Savings Fund (NSF) are payable as from 01 July 2023 are given in the table below:
