Is GST registration mandatory for online sellers?

Short answerYes — if you sell goods through an e-commerce platform like Amazon or Flipkart, GST registration is mandatory from the first rupee, with no threshold benefit. Suppliers of certain services through platforms have limited relaxations.

Mandatory for goods sellers on platforms

The threshold exemption doesn’t apply — you must register before you start selling goods on a marketplace, and the platform also collects TCS.

Some service relaxations

Certain small service suppliers through e-commerce have conditional relief. Confirm the current position for your case.

TCS, reconciliation and the platform setup

For a goods seller on a marketplace, registration is compulsory from the first sale, and the platform deducts Tax Collected at Source (TCS) — a small percentage of the net taxable supplies — before paying you. That TCS appears in your electronic cash ledger and can be claimed once you file, so you reconcile what the platform reports (in its GSTR-8) with your own sales each month. Practically this means your GSTIN must be linked correctly on the platform, your invoices must match what the marketplace reports, and you file GSTR-1 and GSTR-3B like any regular dealer. A recent relaxation lets certain small suppliers sell goods through e-commerce without registration if they stay within a single state, below the threshold, and obtain only an enrolment number — but the conditions are specific, so confirm the current position before relying on it. Service suppliers on platforms have their own limited relaxations. The recurring work is the monthly reconciliation: matching marketplace settlement reports, TCS credited, returns and refunds, and your books, so that the tax paid and the credit claimed line up and don’t trigger a mismatch notice later.
