Non-compliance in Employee Registration and Contribution Payment
Not registering employees on their dates of entry and non-payment of contributions are serious non-compliances.
When you register an employee after ten days of their joining, the system will automatically generate a show-cause notice, and you have to explain the reason for the delay in registration. You can register them now, but for all benefits, the date of registration would be treated as the date of joining.
Retrospective ESI Payment
To pay ESI retrospectively, you will have to provide the actual date after replying to the show-cause notice. In the case of those who were registered but contributions were not paid, you can pay now, but with interest and penal charges.
