However, a person who is required to deduct tax under section 194-IA can use PAN in place of TAN as he is not required to obtain TAN. Under Section 203A of the Income Tax Act, 1961, it is mandatory to quote Tax Deduction Account Number (TAN) allotted by the Income Tax Department (ITD) on all TDS returns.
