cn TDS receivable balance of past years b carried forwaded?

 Past year claim can't be setoff against current year or later liability. But it will refunded by income tax department if you have refund(i.e., TDS is more than tax payable). 

If you find any problem find a chartered accountant office who are specialized in income tax dealing. But it is true that most of refunds are yet to be disbursed by department.
