How can a deductor know his TAN if he has an old TAN, or if he has earlier applied for TAN but hasn't got TAN?

TIN Facilitation Centres will help the deductors in ascertaining their correct TAN from the database. TAN can also be verified from the information on the website of Income Tax Department at www.incometaxindia.gov.in. Using the "Know Your TAN" facility at www.incometaxindia.gov.in or https://incometaxindiaefiling.gov.in the deductor can know his TAN.
