Filing monthly returns is an essential aspect of this compliance as it allows employers to declare the wages paid and the contributions made to the ESIC on behalf of their employees for that particular month. The return also provides information on the number of employees, their salaries, and the contributions made towards the ESI fund, which is used to provide the benefits to the employees.

Filing ESI monthly returns on time helps ensure that the employees receive the benefits they are entitled to, and it also helps the employers avoid penalties and legal complications that may arise from non-compliance with the ESI Act.
