What is GSTR-8?

GSTR-8 is a monthly statement that must be filed by e-commerce operators who manage online marketplaces where other vendors sell goods and services to customers. This return includes detailed information about supplies made through the platform by both registered and unregistered sellers, basic details of the customers, the amount of tax collected at source (TCS), tax payable, and tax paid. Additionally, the GSTR-8 form allows for the seamless transfer of tax credits to suppliers, as the tax collected at source is reflected in the suppliers’ electronic cash ledger, enabling them to claim credit against their tax liabilities.

Who should file GSTR-8?

GSTR-8 Form must be filed by every e-commerce operator who is registered under GST laws and is required to collect Tax Collected at Source (TCS) on outward supplies of goods and/or services made through their e-commerce portal or platform. This includes all e-commerce operators facilitating sales by taxable persons registered on their platform.

GSTR-8 Due Date

The due date for filing GSTR-8 is the 10th of the month following the relevant tax period. This means that e-commerce operators must file their GSTR-8 return for each month by the 10th of the next month. For example, the GSTR-8 for the month of March must be filed on or before the 10th of April. 

Details to be provided in GSTR-8 Returns

The GSTR-8 return consists of nine key sections that e-commerce operators must fill out accurately to ensure compliance with GST requirements. Below is a breakdown of each section:

1. GSTIN

Enter the GSTIN of the e-commerce operator. In case a GSTIN is not yet allotted, the provisional ID can be used for filing purposes.

2. Legal Name of the Registered Person:

The legal name of the taxpayer will automatically appear based on the login credentials used on the GST Portal.

3. Details of Supplies Made Through the E-commerce Operator:

This section requires reporting the gross value of supplies made to both registered and unregistered persons, along with the value of supplies returned by them. The net amount, calculated as the difference between supplies made and returns, is the amount on which TCS will be applicable.

4. Amendments to Details of Supplies from Previous Returns:

Any corrections or modifications to data reported in earlier GSTR-8 statements can be made in this section, ensuring accurate reporting.

5. Details of Interest:

If there has been a delay in the payment of TCS, interest is levied, and the details of such interest amounts must be reported here.

6. Tax Payable and Paid:

This part captures the total tax liability under SGST, CGST, and IGST, along with the tax already paid by the e-commerce operator.

7. Interest Payable and Paid:

An interest rate of 18% is applicable on late payments of GST, and this section reflects the interest amount calculated on outstanding tax liabilities.

8. Refund Claimed from Electronic Cash Ledger:

Refund claims can be made from the electronic cash ledger, but only after the complete discharge of TCS liabilities for the relevant tax period.

9. Debit Entries in Cash Ledger for TCS/Interest Payment:

After payment of tax and filing of the return, the amounts debited from the cash ledger will be reflected. Additionally, the tax collected at source will be transferred to Part C of the supplier’s GSTR-2A once GSTR-8 is filed.

Penalty for Not Filing GSTR-8

If GSTR-8 is not filed within the due date, a late fee of ₹100 per day under CGST and ₹100 per day under SGST is levied, totaling ₹200 per day. However, this penalty is capped at a maximum of ₹5,000. There is no late fee applicable for IGST in case of delayed filing. In addition to the late fee, the taxpayer must pay interest at 18% per annum on the outstanding tax amount. This interest is calculated from the day after the due date until the actual date of payment. 

Pre-requisites for Filing GSTR-8 

Before filing GSTR-8, e-commerce operators must ensure the following conditions are fulfilled:
