The TAN number is allotted by the Income Tax Department, based on applications submitted to the Tax Information Network (TIN) or the TIN facilitation Centres. TAN numbers can be allotted to firms, companies, government departments or individuals. The TIN facilitation centres are managed by National Securities Depository Limited (NSDL). Once TAN number has been allotted, NSDL will intimate the TAN at the address mentioned for all future correspondence related to TDS/TCS.
