Generally, every company submits Monthly returns, i.e., Form 12A(R), Form 5, and 10, along with triplicate challan. After the completion of one year period, i.e., from March to February, every employer submits Form 6A along with Form 3A, which is called Yearly returns.
First, you will receive Form 19 and 10C from the PF office. Fill out all columns correctly and then submit it to your previous organization for obtaining a signature. After that, you will submit it directly to the PF office. If the authorities of your previous company are unwilling to sign the withdrawal form, there may be some misappropriation of your PF amount. In that case, you should contact the P.F Regional Commissioner directly and explain the matter. They will take immediate action.
Wishing you good luck.
