An e-commerce seller in Mumbai operates under a GST framework that differs from a conventional trader’s. The marketplace collects tax at source under Section 52, the seller must reconcile the TCS credit with its own output tax, and the registration trigger is not limited to the turnover threshold: inter-state supply and supply through an e-commerce operator can require registration regardless of turnover.
The TCS Mechanism
The e-commerce operator collects TCS at the notified rate on the net taxable supplies and reports it in GSTR-8. The seller’s TCS credit appears in its electronic cash ledger and can be used against output tax. The seller should reconcile the marketplace’s TCS certificate with its own sales register and GSTR-3B. A mismatch is a common scrutiny trigger.
The Registration Triggers
A seller supplying through an e-commerce operator may be required to register even below the threshold, subject to the exemptions for specified categories. Inter-state supply also triggers registration. The seller should map each channel—own website, marketplace, social commerce—and determine the registration obligation for each.
The Invoice and Return Discipline
The seller should issue GST-compliant invoices for every supply, maintain the HSN at the required digit level, and reconcile GSTR-1 with the marketplace’s GSTR-8. The annual return and reconciliation statement should tie the marketplace TCS to the seller’s turnover.
What the Consultant Does
The consultant assists with the registration mapping, the TCS reconciliation, the invoice discipline and the notice response. The value is in the reconciliation architecture that keeps the marketplace data and the seller’s returns aligned.
