Mr. Rahul,
Form 19 is used for withdrawal of employee's contribution and Form 10 C is used for withdrawal of EPS (Employer part payment). If you deny for pension scheme certificate then only you will get this contribution. If you say "YES" for pension scheme, you will get lamination. As per revised EPFO circular, TDS is applicable withdrawal of PF before completion of 5 years, which please note. Always maintain and guide people to transfer the PF amount, this is only a saving that will be useful at the time of retirement to a private employee. Always thinking about withdrawing and spending is not advisable.
Secondly, you are eligible for claiming pension on and after crossing 50 Years, Lesser percentage than when you get pension after crossing 58 years. This is upto you to take a decision.
Once you withdraw your contributions or employer contribution, you cannot use the same number in new organisation.
