Introduction
GST compliance for e-commerce sellers is more complex than regular businesses due to marketplace involvement, TCS (Tax Collected at Source), and multiple return obligations. Whether you sell on platforms like Amazon, Flipkart, Meesho, or your own website, correct and timely GST return filing is essential to avoid mismatches, penalties, and ITC loss.
This Saving Mantra guide explains the step-by-step process for e-commerce seller GST return filing, applicable returns, due dates, and compliance best practices.
Who Is an E-Commerce Seller Under GST?
An e-commerce seller is a person who supplies goods or services through an electronic commerce operator (ECO). These sellers are mandatorily required to obtain GST registration, irrespective of turnover (except certain service providers as notified).
GST Registration Requirement for E-Commerce Sellers
GST registration is mandatory if you:
- Sell goods through an e-commerce platform
- Supply through marketplaces collecting TCS
- Make inter-state taxable supplies
Threshold exemption generally does not apply to e-commerce sellers of goods.
GST Returns Applicable to E-Commerce Sellers

- Details of outward supplies
- Includes B2C and B2B sales
- Filed monthly or quarterly (QRMP)
2. GSTR-3B

3. GSTR-2B (Auto-generated)

Note:
GSTR-8 is filed by the e-commerce operator, not by the seller.
