One of our employees resigned from the job on 31.03.2020. The bonus payable to the employee for the FY 2019-20 was sent to the bank through the salary account of the employee. It was learned that the employee had closed the salary account, and the cheque was returned by the bank. We tried to contact the employee using the official contact details. However, the employee no longer resides at the provided address. What action should we take regarding the bonus payable amount?
