Dear Mr.Kumar !
Yes.
PF deduction is compulsory.
There is a Statutory Act regarding the PF i.e. is "The Employees Provident Fund and Miscellanious Provisions Act".
The Major benefit with the coverage of PF is, if any employee works for One day and on any reason if he/she dies, his/her dependant spouce will get the pension for whole life, and two children will get a minimum amount for their education until they get the age of 21 if boy, 25 if girl.
I think you better understood what is the benefit with PF coverage.
Regards.
