GST for online sellers: marketplace, own website and the TCS twist
Selling online changes the GST rules in ways many first-time sellers do not expect. Put your goods on a marketplace and registration becomes compulsory from your first sale, TCS enters the picture, and stock in another state can mean another GSTIN. Here is what actually applies, and where the exceptions sit.

Online selling rewrites the threshold rule
For an offline business, GST usually waits until turnover crosses ₹40 lakh (goods) or ₹20 lakh (services). Online selling breaks that comfort. The moment you list taxable goods on a marketplace that collects TCS — Amazon, Flipkart, Meesho and the like — registration is compulsory from your very first sale, no matter how small your turnover. That single fact surprises more new sellers than any other.
But the picture is not uniform. Whether you sell on a marketplace or your own website, whether you deal in goods or services, and where your stock physically sits all change what applies. This guide sorts those cases out. For the general threshold logic behind it all, see do I need GST registration?, and confirm current rules on gst.gov.in.
Selling goods through a marketplace
Section 24(ix) makes registration compulsory for persons selling goods through TCS-collecting e-commerce operators, regardless of turnover. In practice, the major platforms ask for a GSTIN at onboarding for taxable goods anyway, so you rarely get far without one.
There is one narrow exception, live since 1 October 2023: an unregistered person may sell goods intra-state only through e-commerce, below the threshold, using an enrolment number from the portal — but with no inter-state sales. Because national marketplaces route orders across states, most sellers cannot rely on this and still need a full GSTIN. Service providers on platforms are treated differently: apart from notified services (like restaurant, cab or housekeeping supplied through the platform under Section 9(5)), they keep the ₹20 lakh service exemption.
We have platform-specific guides for the big three: GST for Amazon sellers, Flipkart sellers and Meesho sellers.
Tax Collected at Source — and why the rate matters
When you sell through a marketplace, the operator deducts TCS under Section 52 on your net taxable supplies and deposits it with the government. It is not an extra tax you lose — it lands in your electronic cash ledger to be claimed against your liability. The number to get right:
The TCS rate is 0.5%, not 1%
TCS is 0.5% of net taxable supplies — 0.25% central plus 0.25% state, or 0.5% integrated for inter-state — reduced from 1% with effect from 10 July 2024. Many older articles online still quote the outdated 1% figure, so cross-check the live rate on the portal before relying on it.
The operator reports the TCS it collected in GSTR-8, filed by the 10th of the following month, and that credit reflects in your ledger. The word "net" matters: customer returns reduce your net taxable supplies, so the TCS is calculated after returns are netted off — which is exactly why reconciliation (below) is not optional.
Selling only on your own website
Running your own online store is legally different from selling through a TCS-collecting marketplace. Because there is no operator collecting TCS, the specific compulsory e-commerce trigger does not automatically apply. That does not mean you are off the hook, though:
- If you make inter-state supplies of goods — shipping to customers in other states — you must register on that ground regardless of turnover.
- If you cross the turnover threshold for your supply type, you must register on that ground.
- Payment gateways and business buyers often expect a GSTIN in any case.
So the honest summary is: an own-website seller who stays intra-state and below the threshold might not need to register yet, but most own-website sellers who ship nationally end up needing a GSTIN. Get your specific position checked rather than assuming either way.
Multi-state stock and TCS reconciliation
Two operational realities catch growing e-commerce sellers, and both are worth planning for early:
- Stock in another state needs registration there. If you place inventory in a marketplace fulfilment warehouse in another state, you are generally making supplies from a place of business in that state and need a GSTIN there. Sellers using fulfilment programmes across regions often end up with multiple registrations.
- TCS and report reconciliation. The platform's monthly transaction reports must be reconciled against your GSTR-1 so that sales, returns and net taxable value all match. Mismatches between marketplace reports and returns are a leading cause of GST notices — see GST notices explained.
High-return categories need tighter books
In categories such as apparel, return rates are high, and every return moves your net taxable value and the TCS on it. If your returns and your filed figures drift apart, expect questions. Reconciling platform reports to your returns each month is the fix.
What we do — and what we do not promise
Compliance, not a shortcut around the rules
We help online sellers register, obtain additional-state registrations where stock requires them, reconcile marketplace TCS reports against returns, and file every month on time. What we do not do is promise a way around registration when the law requires it, or claim any special standing — we are a documentation and compliance firm, and the GSTIN is granted by the department, not by us.
If you are still tiny and genuinely intra-state, we will tell you honestly whether the enrolment-number route fits before you rush into full registration. If you are shipping nationally through a marketplace, we will set you up properly the first time so a reconciliation gap never becomes a notice.
Our pricing is fixed and simple: ₹499 one-time for registration and ₹499 a month for return filing, with any government fees separate and disclosed before work begins. Composition is generally not an option for national marketplace sellers — see composition vs regular GST for why.
