Dear Malini,
Form 5A is not a monthly return form, but it is submitted at the time of enforcement and subsequently when any change takes place in the board of directors or owners. The return submitted monthly showing the names and details of newly joined employees is not Form 5A but Form 5. Forms for withdrawal (Form 19, 10C), Pension (Form 10D), forms for advances, and forms for nomination are available on the official websites of the EPFO, whereas Form 5A and related forms are available on demand at the office of the PF Enforcement Officer.
Regards,
Madhu.T.K
