What is GSTR-8?
GSTR-8 is a monthly GST return that e-commerce operators must file if they are liable to collect Tax Collected at Source (TCS) under GST laws. This return captures details of all supplies facilitated through their platform and the TCS amount deducted on these transactions.
Once filed, the TCS data from GSTR-8 is reflected in the suppliers’ GST records, allowing them to claim the TCS credit in their electronic cash ledger for offsetting future tax liabilities.
Who Should File GSTR-8?
E-commerce operators registered under GST who collect Tax Collected at Source (TCS) on the supplies made through their platform must file GSTR-8 each month.

FAQs
When an e-commerce operator deducts TCS from a seller’s sales, the amount is deposited with the government and reported through GSTR-8. This TCS detail then appears automatically in the supplier’s GSTR-2A statement, allowing the supplier to claim input tax credit for the TCS collected. Accurate and timely GSTR-8 filing by the operator ensures the seller’s TCS credits are reflected correctly in GSTR-2A, meaning the deducted TCS can be set off against the seller’s future GST liabilities, thereby reducing their net tax outflow.
To calculate TCS for GSTR-8, first determine the net taxable supplies made by each supplier through your e-commerce platform by subtracting returned goods/services from the total taxable supplies, then apply the applicable TCS rate—1% (0.5% CGST + 0.5% SGST for intra-state or 1% IGST for interstate)—on this net amount, ensuring accurate supplier-wise records and matching invoice details with GSTINs to avoid discrepancies in your GSTR-8 return.
No, if no TCS is deducted in a month, filing GSTR-8 is optional.
Yes, sellers can claim TCS as a credit in their GSTR-2B and adjust it against their GST liability.
