GST on E-Commerce: You listed your first product on Amazon or Flipkart, made a few sales, and then noticed a small deduction on your payment settlement that nobody warned you about. Or maybe your accountant just told you that you need GST registration even though you're making less than ₹20 lakhs a year. Either way, you're now in a rabbit hole of GST rules that seem designed for chartered accountants, not actual sellers.
Most articles either copy-paste the law or give you such a high-level overview that you leave with no idea what to actually do. This article is different. It covers what the rules mean in practice — specifically for people selling on online marketplaces or running their own e-commerce store.
This is the part that catches most new sellers off guard. Under normal GST rules, you only need to register if your annual turnover crosses ₹20 lakhs (₹10 lakhs in special category states). But the moment you start selling through an e-commerce operator — Amazon, Flipkart, Meesho, Myntra, or any similar platform — that threshold disappears entirely.
Section 24 of the CGST Act makes it mandatory for anyone supplying goods or services through an e-commerce platform to register for GST, regardless of how much or how little they sell. You could be selling five items a month. You still need a GSTIN before you list a single product.
This rule exists because the government wants a paper trail for every transaction flowing through these platforms. The platforms themselves are required to collect tax on your behalf — and they can only do that if you have a GST registration number on file.

The definition is broader than people think. An e-commerce operator is any person who owns, operates, or manages a digital or electronic facility through which other people supply goods or services. Amazon and Flipkart are the obvious ones. But this also covers aggregators in the food delivery, cab-hailing, and home services space — which is why Swiggy restaurant partners and Ola driver-partners have their own specific rules under Section 9(5) of the CGST Act.
If you sell through your own website with no intermediary, different rules apply. You're treated as a regular supplier, and the ₹20 lakh threshold does apply to you.
One question that comes up constantly: can a seller under the composition scheme sell on Amazon or Flipkart? The short answer is no. Composition dealers are not allowed to make inter-state supplies, and most marketplace sales involve buyers across states. Even if all your buyers happened to be in the same state, the GST law explicitly bars composition dealers from supplying through e-commerce operators. If you're currently on the composition scheme and want to start selling on a marketplace, you'll need to switch to the regular scheme first.
Every payment settlement you receive from an e-commerce operator comes with a small deduction. That's Tax Collected at Source, or TCS — and it's one of the most misunderstood parts of GST for online sellers.
Here's how it works: when a platform like Flipkart collects payment from a customer on your behalf, it's required to hold back 1% of the net value of taxable sales (0.5% CGST + 0.5% SGST, or 1% IGST for inter-state sales) and deposit it directly with the government. The platform doesn't keep this money — it goes to your GST credit ledger.
A lot of sellers confuse TCS under GST with TDS under Income Tax. They're completely separate mechanisms. TCS under GST (Section 52 of the CGST Act) is collected by the e-commerce operator from the payment it owes you. TDS under the Income Tax Act operates on a different schedule entirely. Both can apply to you simultaneously, which is why your settlement statement can look confusing.
The TCS that platforms collect shows up in your GSTR-2A and GSTR-2B once the platform files its own return — GSTR-8. You can then claim this as a credit while filing your own GST returns, effectively reducing your output tax liability.
Take the example of a seller on Amazon selling home decor items with a monthly turnover of ₹3 lakhs on the platform. At 1% TCS, the platform holds back ₹3,000 every month. Over a year, that's ₹36,000 sitting in their GST credit ledger. Many sellers don't realise they can claim this back — they just watch the deductions happen and assume it's a fee. It isn't. Once you file your GSTR-3B and reconcile with the credit available in your ledger, that ₹36,000 comes back to you as a credit against your tax dues or can even be claimed as a refund if you're in a consistent credit surplus. The catch: you have to actually reconcile.
This is where most sellers get overwhelmed. There are multiple return forms, multiple deadlines, and the rules for marketplace sellers differ slightly from direct-to-consumer sellers.
If you're a regular GST-registered seller supplying through e-commerce platforms, you need to file:
• GSTR-1 — outward supply details (monthly or quarterly)
• GSTR-3B — summary return with tax payment (monthly)
• GSTR-9 — annual return (once a year)
Every transaction in GST requires you to determine the 'place of supply' — because this determines whether you're paying CGST+SGST or IGST. For e-commerce sellers, most sales are to customers in different states, which makes them inter-state supplies. Those attract IGST. The platform collects TCS on IGST at 1% for these transactions.
If you're selling digital goods or software products, the place of supply rules shift again — it becomes the location of the buyer, which creates compliance complexity if you're selling to customers outside India. Zero-rated supply rules come into play for exports, and you may be eligible to claim a refund on input tax credit.
E-commerce operators are required to file GSTR-8 by the 10th of every month, declaring the TCS they've collected from all sellers on their platform. You don't file this — the platform does. But you need to track it because the credit it generates flows into your GSTR-2B. If a platform delays or misfiles their GSTR-8, your credit gets delayed too. This is one of those situations where 'it'll auto-populate' doesn't always mean 'it'll auto-populate on time.'
Most of the confusion I see among e-commerce sellers comes from one of three mistakes. Let's name them directly.
The platform collects TCS on your behalf. That's it. The GST registration, the return filing, the invoice generation — all of that is still your responsibility. Platforms have started being stricter about this; Amazon, for example, requires a valid GSTIN before activating a seller account. But having an active account does not mean you're compliant. Returns still need to be filed.
When you sell on a B2C basis through a marketplace, the platform often generates invoices on your behalf — but not always. And when you sell directly or on a wholesale basis, you're responsible for issuing GST-compliant invoices. These must include your GSTIN, the buyer's GSTIN (for B2B), HSN/SAC codes, and the correct tax rate. Getting this wrong creates reconciliation issues down the line.
Under Section 9(5), certain services — primarily cab aggregation, food delivery, and accommodation booking — require the e-commerce operator itself to pay the GST, not the individual service provider. So if you're an Ola or Uber driver or a restaurant on Zomato, the tax liability has shifted to the platform. This is a significant relief for individual service providers, but many don't know it applies to them.

Yes, you do. The mandatory registration rule for e-commerce sellers applies regardless of turnover. Even a single sale through a marketplace triggers the requirement. Most platforms will ask for your GSTIN before allowing you to list products. If you're found operating without registration, the penalty under GST law can be ₹10,000 or the amount of tax evaded — whichever is higher. Register before you start selling, not after.
The TCS deducted by the platform appears in your GSTR-2B after the platform files its GSTR-8 return. When you file your GSTR-3B, this amount appears as a credit that reduces your total GST liability. If your credits exceed your liability for that period, you can apply for a refund through the GST portal. The key is to reconcile your settlement statements with what appears in your GSTR-2B every month — discrepancies happen, and they need to be flagged early.
No. Composition scheme dealers are not allowed to supply goods through e-commerce operators, as per Section 10(2)(d) of the CGST Act. You'd need to opt out of the composition scheme and migrate to the regular GST scheme. The process involves filing Form CMP-04, after which your composition registration is cancelled and you receive a regular GSTIN. Do this before you start listing — not midway through the year.
This is a real operational issue and it happens. You cannot force the platform to file on time, but you can follow up through the seller support portal with your settlement data as proof. Your credit will appear in GSTR-2B only after the platform files. In the meantime, pay your own GST liability using cash and claim the TCS credit in a subsequent month once it's reflected. Delaying your own return filing because of a platform's GSTR-8 delay is not advisable — you'll incur late fees regardless.
Yes. Digital goods — including e-books, software, templates, stock photos, and online courses — are classified as OIDAR (Online Information and Database Access or Retrieval) services under GST. They attract 18% GST. If you're selling to customers in India through your own website, you're required to collect and remit GST. Exports of services are zero-rated, but the documentation requirements are strict. If you're unsure which category your digital product falls under, a quick consultation with a GST advisor can save you a lot of trouble later.
Getting a GSTIN is the easy part. The compliance — monthly returns, TCS reconciliation, proper invoicing, annual GSTR-9 filing — is where most small e-commerce sellers quietly fall behind. And the GST system doesn't give much grace for 'I didn't know.'
GST on e-commerce in India is genuinely one of the more complex areas of the law, not because the rules are impossible to follow but because there are so many moving parts: your own filings, the platform's filings, the credit flows between them, and the specific rules that apply depending on what you're selling and how. The sellers who manage it well aren't necessarily the biggest ones — they're the ones who set up a clean system early and keep their reconciliations current.
If you're just starting out, get your GSTIN, map out your specific compliance calendar, and don't assume the platform is handling more than TCS. Everything else is your job.
