Mr. Rahul,
Form 19 is used for the withdrawal of the employee's contribution, and Form 10 C is used for the withdrawal of EPS (Employer part payment). If you opt out of the pension scheme certificate, then only will you receive this contribution. If you choose "YES" for the pension scheme, you will receive a pension. As per the revised EPFO circular, TDS is applicable to the withdrawal of PF before completion of 5 years, please take note of this. Always advise people to transfer the PF amount; this is a saving that will be beneficial at the time of retirement for a private employee. Constantly considering withdrawing and spending is not advisable.
Secondly, you are eligible to claim a pension on or after crossing 50 years, with a lesser percentage than when you receive a pension after crossing 58 years. The decision is yours to make.
Once you withdraw your contributions or employer contribution, you cannot use the same number in a new organization.
