Dear Pradeep,
Under Section 205A where a dividend has been declared by a company but has not been paid, or claimed within 30 days from the date of the declaration, the company shall within seven days from the date of expery of the said period of thirty days, transfer the total amount of dividend which remains unpaid or unclaimed to a special account to be opened by the company in that behalf to be called Unpaid Dividen Account of .............. Company Limited / Company (Private) Limited.
Thus, each year a separate account to be opened by the company to be called "XYZ Limited Unpaid Dividend Account for the Year ......"
Practically, open an separate bank account for declaration of dividend each year and if any dividend remain unclaimed or unpaid after 30 days of the date of declartion, change the nominclature of the said account on the 37th day of declaration of dividend.
