Hi Mirza,
Yes, it's very true that those companies with a strength of more than 20 employees have to register themselves with the PF department; it's an obligation of the employer. After registration, they deduct 12% of your basic salary, and the same amount is deducted from their side as well, depositing it with the PF fund.
At the end of every financial year, the PF department provides a statement for each registered individual to the company representative separately. You can collect this statement from them. The statement covers the period from April of the previous year to March of the current year, including any previously deposited amounts.
The PF amount can be withdrawn after leaving the company. Following a 60-day separation, you are required to submit filled-up FORM 10c and FORM 19, the withdrawal forms, to the PF department through the previous employer or directly.
I hope this information helps you.
Regards,
Amit Seth
