Hi,
To give you a gist about PF & ESI. PF is a compulsory contributory fund for an employee's future that is, with this money they are benefitted after retirement. Employee State Insurance Act is funded and run by the government, it is an insurance for employee's health whose gross is Rs. 21,000 or less. Further to this, I have attached a PDF briefing about PF and ESI taken from greytHR. The article will help you in better understanding the concepts.

Hi Sam, Thanks for help me...
Just for re-confirmation, As per my knowledge salary range for PF deduction has again revised. Can you correct me, if I am wrong.
Thanks
