Tax Deduction Account Number (TAN) is a unique 10 digit alphanumeric code allotted by the Income Tax Department to all those persons who are required to deduct tax at the source of income. It is mandatory to quote TAN on all TDS (Tax Deduction at Source) returns (including e-TDS return) or any TDS payment challan. In order to apply for a TAN or to get a change/ correction carried out in an existing TAN record, you are required to submit the requisite application form, which is available at any of the Tax Information Network Facilitation Centres (TIN-FCs) managed by the National Securities Depository Ltd (NSDL). The forms could also be downloaded from the links below

• Form 49B for issuance of new TAN and

• Form for Change or Correction in TAN data

Applicants can submit a duly filled-in application to any of the TIN-FCs. The processing fee for both the applications (new TAN and change request) is Rs.55/- each (inclusive of service tax @ 10.20%).
These applications are digitised by NSDL and forwarded to the Income Tax Department. The Income Tax Department will issue the TAN which will be intimated to NSDL online. On the basis of this, NSDL will issue the TAN letter to the applicant.
Application for change in TAN data can also be made online.
