One of my client has deducted and paid TDS into Central Govt Account but he has not filed TDS Return during last 2 Financial Year due to Non Availability of PAN on the part of Deductees. Now he has been collecting PAN From the Past deductees. it may take some time to complete the process. Now Shall i file TDS Return for the current Financial Year. Because TDS Provisions has been changed making it mandatory for the FY 2012-13 to File return on or before 15th of every quarter. Can i File Returns for the last missing 2 years later?
