The Goods and Services Tax Return 8 is a monthly return to be filed by e-commerce operators registered under GST who are required to collect tax at source. Details of supplies that take place via an e-commerce operator, amount of TCS collected and GSTIN must be specified in GSTR-8. This guide by H&R Block India will help you understand everything you need to know about the Form GSTR-8.

What is TCS or Tax Collected at source?

Where a seller on behalf of the government collects and remits tax from a buyer, it is called tax collected at source. This mechanism is similar to Tax deducted at source (TDS). It is mandatory under the GST regime for an e-commerce operator to collect and remit tax on those transactions which take place through its portal. For example: If Ram sells clothes worth INR 50,000 through Flipkart, Flipkart must collect tax at source on that amount and remit It to the Government.

Who is an e-Commerce Operator?

E-commerce operator means any person who owns, operates or manages the digital or electronic facility or platform for electronic commerce.

When is TCS applicable under GST?

TCS is applicable only to e-commerce operators in the GST regime. E-commerce operators like Jabong, Flipkart, Ebay, Amazon supply both goods and services on which they have to collect tax at the rate of 1% on the net value of taxable supplies. Hence an e-commerce operator must register for TCS and file monthly returns (GSTR 8).
