Necessity Of ESI & PF

Hi All,
I worked in a small IT Company with a strength of 150 employees. But there was no ESI, PF, etc.. Just they were deducting PT and TDS from salary. Is it possible to skip PF and ESI in any company? Is it not mandatory to have PF & ESI? Please clarify my doubt..

Dear Sai Sowmya,
Once the workforce strength crosses 20. the organisation is coverable under EPF act.
However for ESI , the organisations with 10 or more people and within the limit of the notified area are coverable.

Hi Sethupathy,
Thanks for your reply.. Even i know that eligibility criterias for PF and ESI, my question is whether an organisation can skip these two like my previous organisation did?

Dear Sowmiya,
It is not possible to skip this. Even in the later years they will be issued with coverage notice ,then they have to pay the arrears also, from the date in which they have actually coverable.
Try to explain them
All the best,
