For an Indian e-commerce seller, GST compliance depends on what you sell, where you sell it, how your sales are structured and whether a specific registration exception applies. A low turnover alone does not settle the question. Check registration eligibility first, then issue and reconcile the right sales documents, report outward supplies, and follow the return schedule that applies to your GST account.
Does an e-commerce seller have to register for GST?
Not necessarily in every case—but do not assume that turnover below the ordinary registration threshold makes you exempt. CBIC’s sectoral FAQ describes compulsory registration for suppliers selling through an e-commerce operator (ECO) that is required to collect tax at source under section 52 of the CGST Act. That FAQ reflects the general statutory framework; it does not establish every later notification-based exception for certain unregistered goods suppliers.

Whether you must register depends on your product or service, whether it is taxable or exempt, your turnover, the State or Union Territory and place of supply, whether sales are intra-state or inter-state, and the role of the platform. Before relying on an exemption as an unregistered supplier, check the current notification conditions or consult a GST practitioner. The available official guidance does not establish the full current conditions for that exception.

Work through these questions before deciding
- What are you supplying? Identify whether you sell goods or services and whether the supply is taxable or exempt.
- How does the transaction work? Determine whether the website merely advertises your products or an ECO facilitates sales by you and collects customer consideration.
- Where is the supply made? Check the relevant place-of-supply rules and whether the transaction is intra-state or inter-state.
- Does a specific exemption apply? Verify the current notification against your exact category and sales model; do not infer an exemption solely from low turnover.
- Confirm before acting. If the exemption or ECO/TCS status is unclear, get advice based on the actual transactions rather than relying on a general marketplace rule.
CBIC’s published FAQ says a person applying for registration submits Part A of FORM GST REG-01 electronically through the GST Common Portal, declaring PAN, mobile number, email address and State or Union Territory. Complete the application using the portal’s current instructions and accurate business details.

How marketplace and own-site sales differ
Section 52 TCS concerns an ECO facilitating supplies by other sellers; it is not a substitute for a seller’s own GST registration, invoicing or return obligations. CBIC’s FAQ distinguishes a marketplace facilitating third-party sales from an operator selling only its own products on its own site. It says the latter does not collect section 52 TCS on those own-account sales. Its FAQ also states that a person selling their own products through a website has no requirement to collect TCS under that section. This point is about TCS, not whether GST is payable on the sale or whether the seller must register.
| Sales arrangement | What the official guidance says about section 52 TCS | What the seller still needs to assess |
|---|---|---|
| ECO facilitates sales by other suppliers | CBIC’s FAQ describes the operator as collecting TCS on the net value of taxable supplies made through it, reduced by taxable supplies returned during that month. | Registration eligibility, tax on the seller’s supplies, invoices and seller-side return reporting. |
| Operator sells only its own products through its own website | CBIC’s FAQ says section 52 TCS is not collected on those own-account sales. | The operator’s own GST obligations still depend on the supplies and applicable rules. |
| Seller sells through a self-hosted website | CBIC’s FAQ says there is no section 52 TCS requirement for selling one’s own products through a website. | Whether the seller must register and account for GST; the TCS point does not decide either issue. |
These distinctions describe the framework in CBIC’s FAQ. Apply current law and notifications to the actual arrangement, especially where a platform’s role or an unregistered-supplier exception is in question.
What invoices and sales records should you keep?
CBIC’s FAQ says registered persons making taxable supplies generally issue a tax invoice. Composition taxpayers and suppliers of exempt supplies use a bill of supply. The document and tax treatment should match the seller’s status and the supply; marketplace order confirmations or settlement statements do not, by themselves, answer which GST document is required.

GST Portal guidance describes GSTR-1 as the statement of outward supplies and its reporting workflows cover invoice details, recipients, credit and debit notes, consumer supplies and ECO-related supplies. In the online workflow, invoice information includes number, date, invoice value and supply details. Use the live portal instructions for the relevant tax period because reporting tables and requirements can change.
Reconcile platform activity to the documents you report
- Match orders and fulfilled sales to invoices or bills of supply issued.
- Account for cancellations, refunds, returns, credit notes and debit notes in the relevant records and reporting.
- Compare marketplace transaction and settlement statements with sales records, including any TCS entries.
- Check that the GST treatment, recipient details and supply values in the source records agree with what you report in GSTR-1.
This reconciliation is a practical way to reduce mismatches between sales activity and outward-supply reporting; the cited portal guidance does not prescribe a particular accounting product or workflow.
How GSTR-1 filing frequency and reporting work
GSTR-1 is the monthly or quarterly outward-supplies statement for applicable normal and casual registered taxpayers. GST Portal guidance says it must be filed even when there was no business activity in the period, subject to the taxpayer category and applicable law.
| Filing pattern | Ordinary GSTR-1 deadline in GST Portal guidance | Eligibility or qualification |
|---|---|---|
| Monthly | 11th of the succeeding month | Ordinary date in the portal guide; a government notification may extend it. |
| Quarterly | 13th after the quarter ends | Portal guidance says taxpayers with preceding-year turnover up to ₹5 crore, or newly registered taxpayers expecting aggregate turnover up to ₹5 crore, may opt for quarterly GSTR-1 and GSTR-3B, subject to conditions. |
The ₹5 crore figure is the GST Portal’s stated QRMP eligibility ceiling, not a general GST registration threshold. Eligible QRMP taxpayers file GSTR-1 and GSTR-3B quarterly and make monthly tax payments by challan under the scheme guidance. Check eligibility and the account’s portal status rather than assuming the scheme applies. The dates above are ordinary GSTR-1 dates from the portal guide, not a guarantee of the deadline for every period; consult the live return calendar and applicable notifications. The sources cited here do not establish a current general GSTR-3B due date, so check the live calendar for that return.

Portal table requirements have changed over time. The GSTR-1 creation guide says that from the August 2024 tax period, qualifying inter-state B2C invoices above ₹1 lakh are reported as B2C Large; lower-value inter-state and intra-state consumer supplies are handled in consolidated B2C reporting. The guide also notes that from the May 2025 tax period the HSN summary uses separate B2B and B2C tabs. These are period-specific portal instructions: follow the live GSTR-1 workflow for the return you are filing rather than carrying older table assumptions forward.

Does e-invoicing apply to marketplace sellers?
The e-invoice mandate is separate from marketplace onboarding and from section 52 TCS. Official Invoice Registration Portal guidance states that the B2B e-invoice threshold was lowered to aggregate annual turnover of ₹5 crore from 1 August 2023, subject to exemptions and scope. The portal also says an ECO can generate e-invoices on behalf of sellers using its platform. That feature does not establish whether a particular seller is covered.
Check your own preceding-year aggregate turnover, the transaction type, applicable exemptions and current reporting requirements against the live mandate guidance. Do not treat a marketplace’s ability to generate an e-invoice as proof that the seller is either in scope or exempt.
Quick Recap
A practical compliance sequence
- Decide registration status. Map your goods or services, turnover, geography and sales route; verify any claimed exemption in current notifications.
- Set up the correct sales document. Issue a tax invoice or bill of supply as appropriate to your GST status and the supply.
- Capture complete transaction records. Keep invoice data and reconcile it to orders, fulfillment, cancellations, returns, credit or debit notes and platform statements.
- Confirm the return pattern. Check whether you file monthly or are eligible and opted into QRMP; verify the current due date for the specific period.
- Prepare and file outward-supply details. Use the GSTR-1 tables and portal instructions that apply to that tax period, including ECO-related reporting where relevant.
- Check e-invoice applicability independently. Assess the mandate against your own turnover, transaction coverage and exemptions, regardless of marketplace onboarding features.
