The new system is of immense benefit to the common taxpayer. Now a single copy of simplified Challan has to be filled up replacing the earlier quadruplicate Challan. Secondly, it would be possible to obtain an acknowledgement for taxes paid at your own bank branch immediately. Further, the acknowledgment counterfoil with the rubber stamp containing the Challan Identification Number (CIN) assures that the payment accounted for. The Tax payer can view the details of tax paid by him by logging on to http://tinnsdl.com and typing the unique CIN given by the bank. (For more details visit NSDL Home page www.nsdl.co.in). Tax-payer is no longer required to attach copies/acknowledgment of challan with the Return. He should only mention the CIN details in the Income-tax Returns.
