Gaurav Kumar

Understanding GST for E-Commerce Sellers — the specific GST obligations that apply to businesses selling through online marketplaces — starts with knowing exactly what the process involves. Here's a step-by-step breakdown for anyone selling goods or services via e-commerce platforms.

Step 1

Register for GST before listing on a marketplace, if mandated.

Step 2

Provide correct GSTIN details to each platform.

Step 3

Reconcile TCS credited by the platform each period.

Step 4

File returns reflecting sales made through all platforms.

Documents to Keep Ready

Before starting, it helps to have these ready so the process moves without unnecessary back-and-forth:

  • GST registration regardless of turnover, where mandated for online sellers
  • Details of all platforms you sell through
  • Reconciliation of TCS deducted by the platform against your returns
  • Correct HSN/SAC classification for listed products
  • Invoicing compliant with GST rules for online sales
  • Records of platform commission and related expenses

What to Watch Out For

Assuming small online sellers are exempt from registration — this is one of the most frequent slip-ups at this stage, so it's worth double-checking before you proceed.
