E-commerce changes the GST rules for you in one big way: registration is generally mandatory to sell goods through platforms — regardless of turnover.

What the platforms do with your tax

Marketplaces collect a small tax at source (TCS) on your sales and deposit it against your GSTIN. That amount appears in your portal ledger and can be claimed — but only if your returns are filed and reconciled.

Your monthly rhythm as a seller

  • Report platform sales in GSTR-1 (the platform’s reports rarely match your books perfectly — reconcile)
  • Claim TCS credit through the portal
  • Match commission invoices from the platform to claim input credit on fees

Common seller mistakes

Registering in only one state while storing stock in another state’s warehouse (an additional registration may be needed), ignoring returns during zero-sales months, and never claiming the TCS sitting in the ledger.
