GST registration for e-commerce sellers in India — the 2026 guide.
If you sell on Amazon, Flipkart, Meesho, Myntra or your own Shopify store, GST registration is not optional the way it is for offline traders. This guide sets out the statutory position under Sec. 24 of the CGST Act, the TCS mechanism under Sec. 52, and the exact filings your business needs to stay on the right side of the department.
1. Who must register
Section 24(ix) — no turnover threshold applies
The general rule under Sec. 22 of the CGST Act is that a business registers for GST once its aggregate turnover crosses INR 40 lakh (goods) or INR 20 lakh (services) in a financial year. Sec. 24 lists exceptions where registration is mandatory from the first rupee. Two of those exceptions catch almost every e-commerce seller:
- Sec. 24(ix) — Persons who supply goods, other than notified services, through an electronic commerce operator required to collect TCS under Sec. 52. This covers Amazon, Flipkart, Meesho, Myntra, Nykaa, Ajio, FirstCry, Snapdeal, and every similar marketplace.
- Sec. 24(i) — Persons making any inter-state taxable supply. The first invoice you raise to a customer in another state triggers this, regardless of turnover.
The practical consequence: if you plan to sell on any Indian marketplace, or ship physical goods across state lines from your own Shopify or WooCommerce store, you register before your first sale. There is no runway to hit the threshold first and register later.
2. The interstate rule
Why almost every online store crosses this line on day one
Small offline retailers often stay under the turnover threshold their entire working life. Online sellers rarely do. The moment a Delhi-based Shopify store ships a candle to a customer in Bengaluru, Sec. 24(i) applies and registration becomes mandatory.
Common founder trap: assuming that because Shopify itself is not an "e-commerce operator" in the Sec. 52 sense, the seller doesn't need GST. The rule that catches you is not Sec. 24(ix) — it's Sec. 24(i). Interstate supply is the trigger.
Services sold entirely within one state (a coaching class in Pune selling only to Pune customers) can still rely on the INR 20 lakh threshold. But the moment the service is delivered across state lines — an online course, a SaaS tool, a consulting call over Zoom — the same rule applies.
3. TCS under Sec. 52
How marketplaces deduct tax at source, and how you recover it
Every e-commerce operator required to collect TCS deducts 1% of the net value of your sales on the platform: 0.5% CGST + 0.5% SGST for intra-state supplies, or 1% IGST for interstate. "Net value" means gross sales minus returns for the month. The operator files this in Form GSTR-8 by the 10th of the following month, and the credit reflects in your electronic cash ledger.

Reconcile the TCS reflected in Form GSTR-2X against your marketplace payout statement every month. Mismatches are the single most common reason for Sec. 61 scrutiny notices to online sellers.

5. Monthly & annual returns
Your GST calendar as an e-commerce seller
| Return | Purpose | Frequency | Due |
|---|---|---|---|
| GSTR-1 | Outward supplies (invoice-level) | Monthly / QRMP | 11th of next month |
| GSTR-3B | Summary + tax payment | Monthly | 20th of next month |

| GSTR-9C | Reconciliation statement | Annual (if turnover > INR 5 cr) | 31 December of following FY |
6. Common notices
The three notices online sellers see most often
- Sec. 61 — scrutiny of returns. Triggered by mismatch between GSTR-3B outward supplies and the TCS reflected in GSTR-8. Fix: reconcile marketplace payout statements to books each month before filing GSTR-3B.
- Rule 21A — suspension of registration. Issued on non-filing of returns for six consecutive months. Fix: file the pending returns with late fees under Sec. 47 and apply for revocation in Form GST REG-21 within 30 days.
- Sec. 73 — demand for short payment. Common where TCS credit is claimed but the underlying GSTR-8 shows a lower figure. Fix: reconcile at the invoice level and file DRC-06 with supporting workings.
7. Questions
Frequently asked by online sellers
Is GST registration mandatory for e-commerce sellers in India?
Yes. Section 24(ix) of the CGST Act, 2017 requires every person supplying goods through an e-commerce operator (Amazon, Flipkart, Meesho, Myntra) to register under GST — regardless of turnover. The INR 40 lakh / 20 lakh threshold does not apply. For services sold through your own Shopify or WooCommerce store, the standard turnover threshold applies unless you supply interstate.
Do I need GST to sell on my own Shopify store?
If you sell services and stay within your state, the standard threshold (INR 20 lakh for services, INR 40 lakh for goods) applies. But the moment you make an interstate supply of goods, Sec. 24(i) makes registration mandatory from the first rupee. Most Shopify and WooCommerce merchants selling physical products cross this line on day one.
What is TCS on Amazon, Flipkart and Meesho?
Under Sec. 52 of the CGST Act, marketplaces deduct 1% Tax Collected at Source (0.5% CGST + 0.5% SGST, or 1% IGST for interstate) on the net value of your sales. This appears in Form GSTR-8 filed by the operator and reflects in your electronic cash ledger. You can offset it against your monthly output GST liability.
Which GST returns do e-commerce sellers file?
GSTR-1 (outward supplies, monthly or quarterly under QRMP), GSTR-3B (summary + tax payment, monthly), and GSTR-9 (annual return if turnover exceeds INR 2 crore). Reconcile GSTR-8 (filed by the marketplace) against your books each month to confirm TCS credit.
Can e-commerce sellers opt for the Composition Scheme?
No. Sec. 10(2)(d) explicitly bars composition for suppliers making supplies through an e-commerce operator that collects TCS. If Amazon or Flipkart is deducting TCS on your sales, you must be a regular registered taxpayer.
What happens if I sell without GST registration on a marketplace?
Marketplaces will not onboard a seller without a valid GSTIN. If you register a business incorrectly (e.g. as unregistered) and later transact, Sec. 122 attracts a penalty of INR 10,000 or the tax evaded, whichever is higher, plus interest under Sec. 50. Retrospective compliance is filed but late fees and denial of ITC on the intervening period are common.
