Dear KR Mathur Ji,
Your company was liable to obtain a PF code and make the remittance of PF dues from the date your company had 20 or more employees, including contract laborers, irrespective of their salary limit. Your company's liability for PF dues, interest, and damages starts from this date. The same will be calculated based on various records, registers, balance sheets, books of accounts, account ledger, etc.
Thanks for the response and valuable advice. Actually, I wanted to avoid liabilities as I am able to restore the records due to a mix-up of data, whereas I have made all records available according to the balance sheet.
Regards,
KR Mathur
