GST for Ecommerce Business – Complete Guide to Registration, TCS & Compliance in India

What is GST for Ecommerce Business?

GST for ecommerce business refers to the Goods and Services Tax rules and compliance requirements that apply to individuals and businesses selling goods or services through online channels. This includes marketplaces like Amazon, Flipkart, Meesho, social commerce on Instagram and Facebook, independent websites on Shopify, and B2B platforms like IndiaMART. The GST framework mandates registration, collection of TCS by operators, monthly return filing, and input tax credit claims. It is a specialised area because the obligations differ based on how you sell – whether through a third‑party platform that processes payments or through your own website. This guide is your one‑stop resource, and DisyTax has helped over 10,000 ecommerce businesses get compliant. Start with our GST basic terms to understand the fundamentals.

How GST Applies to Ecommerce Businesses in India

The GST law creates two categories of online sellers: those who sell through an e‑commerce operator (marketplace) and those who sell through their own website. For marketplace sellers, the operator is required to collect TCS, and the seller must compulsorily register for GST. For own‑website sellers, the normal turnover thresholds apply. Additionally, the nature of the product or service determines the applicable GST rate. The place of supply rules further decide whether IGST or CGST+SGST is charged. Below we break down each aspect in detail.

Is GST Registration Mandatory for Ecommerce Businesses?

It depends on your sales channel. If you sell on any marketplace like Amazon, Flipkart, Meesho, Myntra, etc., GST registration is absolutely mandatory from the very first sale. There is no turnover exemption. This is because of Section 24 of the CGST Act. If you sell exclusively through your own website (Shopify, WooCommerce) and do not use any marketplace, you need GST registration only when your aggregate turnover exceeds ₹40 lakh (for goods) or ₹20 lakh (for services). Social commerce with in‑app checkout (Instagram Checkout, Facebook Shop) also triggers mandatory registration. For a detailed breakdown, see our guide on is GST mandatory for online sellers.

Section 24 of GST Act and Ecommerce Registration Rules

Section 24 is the legal backbone that makes GST registration compulsory for e‑commerce sellers. It states that notwithstanding anything in Section 22 (which provides the threshold exemption), every person supplying goods or services through an e‑commerce operator who is required to collect TCS must register for GST. This single provision overrides the turnover exemption and covers virtually every marketplace seller. It is also the reason why composition scheme is not available to marketplace sellers. For an in‑depth understanding, read our GST registration for ecommerce sellers guide.

GST Registration Requirements for Ecommerce Businesses

To register, you need to file Form GST REG‑01 on the GST portal. The requirements include a valid PAN, Aadhaar, proof of business address, bank account details, and a photograph. The process takes approximately 7 working days. You can use our online GST registration service for a hassle‑free experience. For multi‑state FBA sellers, additional registrations are required in each state where inventory is stored.

GST for Amazon, Flipkart, Meesho and Other Marketplaces

All major marketplaces operate under the same GST framework. Sellers on Amazon, Flipkart, Meesho, Myntra, Ajio, Blinkit, JioMart, etc., must register, file monthly returns, and have TCS deducted at 1%. Each platform has its own settlement report format, but the reconciliation principles remain the same. We have dedicated guides for each platform:

GST for Shopify and Independent Ecommerce Websites

If you run your own website (Shopify, WooCommerce, custom), you are not automatically subject to marketplace rules. You need registration only when your turnover crosses the threshold. However, voluntary registration is common for ITC benefits and payment gateway requirements. We also cover GST for Shopify stores, GST for dropshipping, and GST for Instagram sellers in detail.

TCS (Tax Collected at Source) Under GST for Ecommerce Businesses

TCS is a 1% tax collected by e‑commerce operators on the net taxable value of supplies. For intra‑state sales, it is 0.5% CGST + 0.5% SGST; for inter‑state, 1% IGST. The operator files GSTR‑8 monthly, and the seller can claim this TCS as credit in GSTR‑3B. TCS impacts cash flow but is fully creditable. Reconciliation of TCS between settlement reports and GSTR‑2A is critical. Explore our comprehensive TCS on e‑commerce guide and the Amazon TCS reconciliation guide.

GST Invoice Requirements for Online Sellers

Every sale must be accompanied by a GST‑compliant invoice. Marketplaces often auto‑generate invoices, but the seller is responsible for correctness. The invoice must contain GSTIN, HSN codes, place of supply, and tax breakup. For B2B sales, the buyer's GSTIN is also required. Our GST invoice format guide provides a ready template.

GST Rates Applicable to Ecommerce Sales

Rates vary from 0% (essentials) to 28% (luxury items). Common rates: 5% (packaged food, footwear ≤₹1000), 12% (mobile phones, butter), 18% (most consumer goods), 28% (cars, cement). Use our GST HSN rate finder to determine the correct rate.

Input Tax Credit (ITC) Benefits for Ecommerce Businesses

ITC allows you to reduce your GST liability by claiming credit on business expenses: marketplace fees (18% GST), advertising, shipping, packaging, and inventory purchases. Proper ITC management can significantly improve margins. See our ITC guide for details.

GST Return Filing Requirements for Ecommerce Businesses

All marketplace sellers must file GSTR‑1 (outward supplies) and GSTR‑3B (summary) monthly, and GSTR‑9 annually. Own‑website sellers with turnover up to ₹5 Cr can opt for QRMP quarterly filing. Timely filing avoids late fees (₹50/day) and keeps your registration active. Get our GST return filing guide for online sellers for a step‑by‑step walkthrough.

GSTR‑1 and GSTR‑3B Filing for Online Sellers

GSTR‑1 reports all sales (B2C state‑wise summary, B2B invoice‑wise). GSTR‑3B is where you claim ITC, TCS credit, and pay tax. Reconciliation between these returns and platform settlement reports is non‑negotiable. Our GSTR‑1 and GSTR‑3B guides explain each field.
