unsecured loans taken by the Partnership Firm

Sorry to ask but whether the concerned Individual is either shareholder or director of the company.

True....if he is the shareholder, it could be treated as "Sharedolders Deposits" under Unsecured Loans and if a director, then loans from Directors under the same group.

If the person from whom the loan has been taken are a director or shareholder of the comapny or their relatives then it will not attract the provisions of Section 58A. But do take a letter from the depositers that the said loan granted to the company was out of own funds.
