Procedure for filing an online application for TAN

The person, who can be referred to as deductor,  can make an application online at the website of NSDL-TIN, which is https://tin.tin.nsdl.com/tan/index.html

  • When the deductor has correctly filled the application, there is a receipt of an acknowledgment that comprises a 14 digit acknowledgment number; the status of the deductor; the name of the deductor; contact details of the deductor; payment details of the deductor; and a signature space.
  • The applicant must ensure that he has saved the receipt of acknowledgment and has obtained a printout of the same.
  • The applicant must sign the acknowledgment and that sign must be done within the confines of the signature box provided.
  • In case the applicant is not an individual, stamp or seal to be affixed.
  • If a thumb impression is made, the same must be attested by Notary Public or Magistrate or Gazette Officer.
  • Payment can be done by demand draft, or cheque, or e-payment. In case of a cheque or a demand draft, the payment is to be made in favor of the NSDL-TIN.


It is to be noted that one must never use a PAN in the field which requires quoting of TAN. If the deductor does not have TAN, then he should make an application for the same. There is, however, an exception because, under the provisions of Section 194-IA, one can make use of PAN instead of TAN but that is only an exceptional case.
