Dear Raj
The PF contribution is payable by 15th of the following month. In case of delayed remittance interest @ 12% per annum is payable. If interest is not paid the PF authorities can initiate proceeding under Section 7Q of the Act.
In addition they can also initiate proceeding under Section 14B and claim damages depending upon the number of days default in remittance.
