TDS on e commerce payouts requires operators to deduct tax when crediting or paying participants, subject to PAN and threshold exceptions. Section 194O requires e commerce operators to deduct tax at source when amounts of sale or services are credited to or paid to e commerce participants through the operator's digital platform, including amounts paid directly by purchasers if the transaction was facilitated by the operator; receipts for advertising or unrelated services are excluded; the operator's deduction under this section precludes deduction under other Chapter provisions for the same transaction.
