The minimum bonus that an employer is required to pay, even if he suffers losses during the accounting year or there is no allocable surplus, is 8.33% of the salary during the accounting year. The balance payable is "Set Off".
Now you have mentioned that you were paid the minimum, and the remaining amount has not been paid yet. As per the Bonus Act, in a situation where for any accounting year there is no available surplus or the allocable surplus falls short of the minimum bonus payable to the employees, and there is no amount or sufficient amount carried forward and set on that could be utilized for the purpose of payment of the minimum bonus, then such minimum amount or the deficiency, as the case may be, shall be carried forward for being set off in the succeeding accounting year and so on up to and inclusive of the fourth accounting year.
I hope this is the information you have been looking for.
