GST Return Filing for E-commerce Sellers
GSTR-1 and GSTR-3B filing for marketplace and website sellers, with sales, returns and TCS reconciled.
Get Started Today
GST return filing for e-commerce sellers is the periodic compliance that businesses selling through online marketplaces, their own websites or social channels must complete under GST. It suits any seller whose orders are routed through an e-commerce operator, because the marketplace dashboard rarely matches the books exactly. Our team prepares GSTR-1 from your order data, reconciles marketplace settlement reports, files GSTR-3B and checks the tax collected at source that operators report against your GSTIN. Sales returns, cancellations and refunds are treated as the GST law requires, so your liability is not overstated and your credits are not missed. Forms and dates are set by the GST Council and the portal, and we confirm them each period.

How It Works
Collect marketplace and store data
We gather the sales, return and settlement reports from every marketplace and your own website, along with purchase invoices and your last filed returns, so nothing sold is left out.
Reconcile orders with books
Order-level data is matched with payouts and accounting entries. Differences such as commissions, shipping fees, cancelled orders and customer refunds are identified and explained before any figure is reported.
Prepare and file GSTR-1
Outward supplies are classified by type, state and tax rate, credit notes are recorded for returns, and GSTR-1 is shared with you for confirmation before it is filed on the GST portal.
Check TCS and input credit
We compare the tax collected at source reported by operators against your expected amounts, and review purchase credits against the auto-drafted statement so only eligible credit is taken.
File GSTR-3B and pay tax
GSTR-3B is prepared with the liability, credit and any TCS adjustment worked out. Once you approve it, we guide the payment and file the return within the portal timeline.
Keep a reconciliation file
You receive a short reconciliation note showing how marketplace data, books and returns tie together, which becomes useful for annual return preparation and any later departmental query.
Documents Required
- GST registration certificate and portal login access
- Marketplace sales and settlement reports for the period

- Own website or social commerce order and payment data
- Purchase invoices for goods, packaging and services used

Timeline and Fees
Indicative timeline: Monthly or quarterly filing cycles apply, with the due dates notified on the GST portal. A first-time reconciliation of marketplace data usually takes a few working days, depending on how clean your order records are.
Professional fee: The fee depends on how many marketplaces and states you operate in, the monthly order volume, the quality of your records and how often returns must be filed. We confirm the scope in writing after reviewing a sample month of data.
What Can Go Wrong if This Is Missed or Done Incorrectly
- Late filing of GSTR-1 or GSTR-3B attracts a late fee and interest on unpaid tax under the GST law
- Understating sales compared with marketplace-reported data can invite a notice and a demand for tax
- Wrongly claimed input credit may have to be reversed with interest
- Unreconciled TCS credit can sit unused, locking up working capital
- Continued non-filing can lead to the department restricting e-way bill generation or cancelling the registration
Frequently Asked Questions
Do I file GSTR-1 and GSTR-3B if I sell only on Amazon or Flipkart?
Yes. A registered seller on a marketplace files its own outward supplies return and summary return like any other taxpayer. The marketplace does not file these for you. The operator files a separate statement for tax collected at source, but your own returns remain your responsibility.
What is GSTR-8 and does a seller have to file it?
GSTR-8 is the statement filed by the e-commerce operator, not by the seller, to report the tax it collected at source from supplier payouts. Sellers do not file it. They only need to check that the amounts the operator reports against their GSTIN match what was actually deducted.
How do I claim credit for TCS deducted by the marketplace?
The tax collected at source by an operator is reported against your GSTIN and shows up on the GST portal after the operator files its statement. You review it, and the credit is taken through the portal mechanism into your cash ledger. Our team verifies the amounts first so that mismatches are raised early.
How are customer returns and refunds shown in GST returns?
When a customer returns goods, the original supply is adjusted through a credit note, and the reduction is reported in a later GSTR-1, with the tax effect reaching GSTR-3B. The adjustment must follow the time and condition limits in the GST law, so returns accepted late need careful handling.
Can mismatched marketplace data cause a GST notice?
It can. Departments compare your declared sales with data reported by marketplaces and payment channels. If your returns show lower turnover than operators report, a notice or intimation may follow. Regular reconciliation between order data, payouts and returns is the practical way to avoid that situation.
Do I need a separate registration for each state I ship from?
Generally a seller needs registration in each state from which it stores or supplies goods, for example when stock sits in a marketplace fulfilment warehouse in another state. The exact position depends on your set-up. See our e-commerce GST registration page and ask our team to review your inventory locations.
