What TAN Adv Is Used For

Deductor verification

Confirm a TAN belongs to the organisation named on a TDS certificate before you accept it.

Employer and payroll onboarding

Verify an employer TAN with its registered address and contact details during business KYC.

TDS compliance

Validate the TAN on file before filing returns, so a rejected filing does not cost you a penalty.

Vendor master cleanup

Re-verify TAN records across a supplier database and correct stale addresses.
