<s>[INST] Can we quote Permanent Account Number (PAN) in place of TAN? [/INST] No. PAN should never be quoted in the field where TAN is required to be quoted. The purposes for which PAN and TAN are allotted are different. TAN is a unique identification number which is allotted to persons who are required to deduct tax at source or collect tax at source.

PAN is a unique identification number issued to keep a linking of the transactions carried by a person like payment of tax, TDS/TCS credit, return of income, return of wealth, correspondence with the Income Tax Department or correspondence by the Income Tax Department, investments made by a person, loan taken by a person, etc. However, a person required to deduct TDS as per section 194IA or section 194IB or section 194M​, can use PAN in place of TAN. </s>
