In case duplicate TANs have been allotted, the TAN which has been used regularly should be continued to be used. The other TAN/s should be surrendered for cancellation using 'Form for Changes or Correction in TAN' which can be downloaded from NSDL-TIN website or may be procured from TIN-FCs or other vendors.
Ours is an organization into alcohal business. We need to collect TCS from the buyers while supplying goods to them and file the quarterly TCS returns. The organization has multiple TAN no and I was told that we are required to have a separate TAN no. for every State. Is is correct that an an organization needs to obtain separate TAN for every State in which it carries on the business?
