India GST e-commerce treatment depends on the legal supplier, operator, place of supply, registration status, product classification, and payment flow. Marketplace TCS, operator-paid tax for notified services, and foreign OIDAR rules are separate mechanisms.
Key takeaways
GST registration is state-specific and should follow the entity and place from which supplies are made.
E-commerce operators can have registration and tax-collection-at-source obligations for supplies by other sellers.
Returns reduce the net value used for relevant TCS calculations when the statutory conditions apply.
Foreign suppliers of OIDAR services to non-taxable online recipients in India have a dedicated registration and payment analysis.
Map entities, states, warehouses, and GSTINs
Start with legal entities, principal and additional places of business, warehouses, marketplace fulfillment locations, dispatch states, customer states, and invoicing flows. GST registration is PAN-based and state-specific, so one GSTIN should not be applied across every fulfillment location without analysis.
Connect each order to the supplying registration and determine whether it is intra-state or inter-state under place-of-supply rules. A marketplace warehouse can change operational facts even when the platform handles customer acquisition.
- Maintain an entity-and-state registration matrix.
- Map inventory movement and dispatch locations.
- Validate GSTINs and invoice ownership.
- Review new fulfillment locations before use.
Separate operator, seller, TCS, and section 9(5) roles
An e-commerce operator owns, operates, or manages a digital facility or platform. Operators can collect TCS on the net value of taxable supplies by other registered sellers when consideration is collected by the operator. That is different from notified services for which the operator pays GST as if it were the supplier.
A merchant selling its own goods through its own website does not collect TCS from itself merely because the website is electronic, although ordinary GST can still apply. Build a channel matrix showing seller, invoice issuer, consideration collector, TCS collector, tax payer, refund owner, and return disclosure.
- Do not confuse TCS with output GST.
- Map section 9(5) services separately.
- Reconcile platform statements to seller books.
- Store the effective law and notification.
Handle registration, taxability, and place of supply
Classify goods and services under the relevant HSN or SAC framework and confirm the current rate and exemption. Determine place of supply, time of supply, value, reverse-charge status, and whether CGST/SGST or IGST applies. Product labels in a catalog are not a legal classification.
Registration requirements for sellers using operators have changed over time and can include notified exceptions, so use current CBIC and GST portal guidance rather than an old general summary. Foreign or non-resident sellers need a specific entry and registration analysis.
- Version rate and classification decisions.
- Document place-of-supply evidence.
- Test discounts, shipping, bundles, and credit notes.
- Review threshold exceptions before launch.
OIDAR services supplied from outside India
Online information and database access or retrieval services can include automated internet-delivered offerings with minimal human intervention. Foreign suppliers serving non-taxable online recipients in India may need simplified registration, collection, invoicing, and filing.
Determine recipient status and location using reliable evidence, and distinguish B2B transactions where reverse-charge consequences may apply. Platforms and intermediaries require their own analysis based on contractual and payment control. Store the decision with the customer and order record.
- Maintain an OIDAR product list.
- Capture recipient GST registration status.
- Use documented customer-location indicators.
- Review platform responsibility separately.
Invoices, returns, TCS reconciliation, and controls
Issue invoices and credit notes with the correct GSTIN, place of supply, classification, taxable value, rate, and tax components. Reconcile GSTR data, operator statements, TCS credits, returns, cancellations, payment settlements, electronic ledgers, and books before filing.
Returns can reduce the relevant net taxable-supplies base for operator TCS, but the order, return, and reporting period must be traceable. Investigate mismatches quickly because they can affect cash flow and credits. Preserve registration records, filings, challans, notices, and supporting exports.
- Match each return to the original order.
- Reconcile TCS credits to operator reports.
- Keep state registrations and ledgers separate.
- Assign owners for portal notices and corrections.
Frequently asked questions
Is GST registration in India nationwide?
No. GST registration is PAN-based and state-specific, so businesses may need registrations in multiple states based on their places and supplies.
Is marketplace TCS the same as the seller’s GST?
No. TCS is collected by the operator under section 52 on the relevant net value; the seller still accounts for its output GST unless another rule shifts liability.
Does a seller’s own website create a TCS obligation?
Selling your own products on your own website does not by itself require collecting TCS from yourself, though ordinary GST obligations remain.
What is OIDAR?
OIDAR covers specified automated online information and database access or retrieval services, with special rules for foreign suppliers to Indian non-taxable online recipients.
