TAN (Tax Deduction and Collection Account Number) is a 10-character alphanumeric code assigned by the Income Tax Department of India to entities tasked with deducting or collecting taxes at source.
It is mandatory for all individuals and organizations—such as tax deductors, tax collectors, and government bodies—involved in TDS (Tax Deducted at Source) or TCS (Tax Collected at Source) processes.
TAN must be mentioned in all related returns, challans, and communications submitted to the government concerning TDS and TCS transactions.
