Dear Rupesh,
When the provision of an Act or the Rules framed under the same requires the employer or another person to do something in a particular manner, they are obligated to do it in that manner and not otherwise. Maintenance of registers, issuance of wage slips, collection of nominations, and exhibition of notices in physical forms cannot be dispensed with due to the availability of the required details in electronic form unless there are specific statutory exemptions in this regard.
Rule 26(2) of the Minimum Wages (Central) Rules, 1950
Rule 26(2) prescribes the issuance of wage slips in Form XI. Your State Payment of Wages Rules would have a specific rule for the issuance of salary/wage slips to the employees.
Purpose of Issuing Wage Slips
The purpose of this provision is to enable the employee to know their gross salary, deductions, and net salary. Therefore, you cannot skip this just because of the payment through ECS.
