GST Registration for E-Commerce Sellers — Mandatory Regardless of Turnover
Section 24(ix) of the CGST Act mandates GST registration for every person who supplies goods or services through an e-commerce operator. This is an absolute mandatory registration provision — unlike the threshold-based registration for other businesses, there is no minimum turnover exemption for e-commerce sellers. A home baker selling Rs.10,000 worth of goods on Amazon, a craftsperson listing handmade products on Flipkart, or a reseller using Meesho must all be GST-registered before making their first sale.nnThe mandatory registration requirement exists because e-commerce platforms operate as TCS collectors under Section 52 of the CGST Act. The platform deducts 1% TCS on every settlement to the seller — this TCS mechanism only works if the seller has a valid GSTIN on record with the platform. Amazon, Flipkart, and all other registered e-commerce operators in India require sellers to submit their GSTIN during the seller onboarding process. Sellers without GSTIN cannot complete the onboarding and cannot list products for sale.nnOne important exception was introduced by the CBIC: state-wise notified persons making intrastate supply through e-commerce platforms have been given a threshold exemption in certain states. Under this notification, small sellers making sales only within their own state on certain platforms can use the threshold limit applicable to intrastate suppliers. However, this exception is state-specific and platform-specific and is not a universal exemption. For most practical purposes, any seller planning to sell on national e-commerce platforms serving customers across India should assume mandatory GST registration from the start.
TCS by E-Commerce Operators — 1% on Net Sales Value
Section 52 of the CGST Act requires e-commerce operators — Amazon, Flipkart, Meesho, Myntra, Nykaa, Ajio, Swiggy, Zomato, Ola, Uber, and any other platform facilitating supply of goods or services — to collect TCS at 1% of the net value of taxable supplies made by sellers through their platform. The TCS is collected at the time of payment to the seller (settlement) and deposited with the GST government by the 10th of the following month.nnThe 1% TCS is split as 0.5% CGST and 0.5% SGST for intrastate sales and 1% IGST for interstate sales. The TCS is computed on the net value — which means the amount after returns and cancellations, not the gross sales figure. For example, if a seller's monthly gross sales on Amazon are Rs.5 lakh but Rs.50,000 in orders were returned, the TCS base is Rs.4.5 lakh and TCS is Rs.4,500 (1% of Rs.4.5 lakh). The platform deducts this Rs.4,500 from the monthly settlement and deposits it with the government.nnFrom the seller's perspective, the 1% TCS appears in their Form 26AS equivalent for GST — the GSTR-2A and GSTR-2B statements — as a credit. Sellers claim this TCS as ITC credit in their GSTR-3B return in Table 4(A)(1). The TCS credit offsets the seller's output GST liability. For a seller paying 12% or 18% GST on their products, the 1% TCS from the platform is effectively an advance payment of 1/12th or 1/18th of the output tax — reducing the cash required for monthly GST payment.

GST Returns for E-Commerce Sellers — GSTR-1 and GSTR-3B
E-commerce sellers file the same standard GST returns as other registered taxpayers — GSTR-1 (outward supply statement) and GSTR-3B (monthly summary return). For most small and medium e-commerce sellers with turnover below Rs.5 crore, the QRMP scheme (Quarterly Return Monthly Payment) is available, allowing quarterly GSTR-1 and GSTR-3B filing with monthly advance payments. However, given the high frequency of interstate sales on e-commerce platforms, monthly filing may be more practical for sellers with large volumes.nnIn GSTR-1, e-commerce sales to unregistered buyers (which is most B2C e-commerce) are reported in Table 8 (B2C small) as consolidated state-wise totals, or in Table 7 (B2C large) for individual sales above Rs.2.5 lakh in the inter-state category. E-commerce sellers rarely have B2B invoice-level reporting requirements unless they sell to registered business buyers — a less common scenario in retail e-commerce.nnFor GSTR-3B, the outward supply from e-commerce platforms must be accurately declared in Table 3.1(a). The TCS credit from the platform is claimed in Table 4(A)(1). A common mistake among e-commerce sellers is declaring only the settlement amount received from the platform (net of TCS and platform commission) as their taxable turnover — this is incorrect. The full sale value (gross revenue to the customer) is the taxable turnover, not the net settlement. The platform commission is a business expense in the income statement but does not reduce GST taxable turnover.
Composition Scheme and E-Commerce — Strictly Prohibited
One of the absolute prohibitions in the GST composition scheme is that composition dealers cannot supply goods through e-commerce operators. Section 10(2)(d) of the CGST Act explicitly states that a composition dealer is ineligible if they are a person who makes supply of goods through an e-commerce operator. This prohibition applies to all e-commerce platforms — Amazon, Flipkart, Meesho, Myntra, and any other operator.nnA business that is under the composition scheme cannot register as a seller on any e-commerce platform — doing so would automatically disqualify them from the composition scheme and make them liable for regular GST on their entire turnover for the year, including penalties. Businesses considering selling on e-commerce platforms must first check if they are under the composition scheme and if so, exit the composition scheme before registering as an e-commerce seller.nnThe prohibition exists because composition dealers issue bills of supply (not GST invoices), do not charge GST to customers, and pay a fixed percentage of turnover as composition tax. E-commerce platforms operate on the assumption that sellers collect GST from customers and provide GST invoices — the TCS mechanism and ITC framework only work with regular GST taxpayers. The incompatibility between composition scheme and e-commerce selling is fundamental and cannot be worked around.
ITC on E-Commerce Business Expenses — What Can Be Claimed
E-commerce sellers who are regular GST taxpayers can claim Input Tax Credit on their business input expenses, significantly reducing their net GST outflow. Key ITC-eligible expenses for e-commerce sellers include: packaging materials (boxes, bubble wrap, tape, labels) at applicable GST rates; warehousing and fulfillment centre fees paid to Amazon FBA, Flipkart Fulfillment, or third-party logistics providers at 18% GST; photography and product listing services for creating product images; catalogue management and content writing services; advertising on the platform and social media; accounting and CA fees for GST compliance; and shipping and courier services for seller-fulfilled orders.nnPlatform commission (referral fee) paid to Amazon, Flipkart, or Meesho attracts 18% GST as a service fee. E-commerce sellers registered for GST can claim ITC on this 18% commission GST, effectively reducing their net commission cost. For a seller paying Rs.1 lakh in monthly Amazon referral fees, the GST on commission is Rs.18,000. Claiming this as ITC reduces the seller's monthly output tax liability by Rs.18,000 — a meaningful saving for sellers with significant platform fees.nnInventory purchases for resale attract GST at the applicable rate for the product category — typically 12% or 18% for most goods. This input GST on purchases is fully claimable as ITC. E-commerce sellers should ensure all supplier invoices are in the seller's GSTIN name and that suppliers are GST-registered and filing their returns — supplier non-compliance directly reduces the seller's GSTR-2B ITC availability.
