For every e-commerce operator, filing GSTR-8 is a must to accumulate TCS(Tax Collected at Source), for all taxable supplies made through it. The tax collected at source by thee-commerce dealer and the complete information for these supplies needs to be mentioned every month by visiting the GST portal, in the Form GSTR-8.

Every month, one can file the return in Form GSTR-8 by visiting the GST Portal. However, the GSTR-8 filing for a specific month needs to be done upon completing that particular month.

In this article we will find out more about GSTR 8 format, eligibility to file, due date, penalties, the return filing process.

Let’s get started!

What is GSTR-8 Return?

GSTR-8 is an exceptional GST Return that needs to be filed by e-commerce companies that deduct Tax Collected at Source(TCS) from their customers. The return consists of supplies that an e-commerce operator makes through their online platform and TCS collects on these supplies.

Every e-commerce company operating and making supplies in India needs to file GSTR-8 and be registered under GST. For GST, any person who makes supplies through an online platform is treated as an e-commerce operator.

For Example, Mr. A registered himself in www. amazon. In and sold laptops through amazon. Any sale made on amazon, the amount is received by amazon and later paid to Mr. A at the end of the month. Amazon will deduct his commission and also collect TCS from Mr. A. The rest amount will be paid to Mr. A. Then amazon needs to file GSTR 8 showing all supplies made through his platform.

The Purpose of GSTR-8 Form

The primary purpose of the GSTR 8 format is to maintain the right information regarding the TCS amount which e-commerce operators collect on supplies made through their platform.

It ensures that there is a seamless flow of input credit to the suppliers who have paid TCS to the e-commerce operator. In Part C of the GSTR-2A return form, the respected supplier can view the TCS details.

The collected TCS by the e-commerce operator goes directly to the government, which the concerned supplier can eventually recover through the Input credit mechanism.

Due Dates for Filing GSTR-8 Form

An E-commerce operator can file GSTR-8 after the month ends and the last date to file the details is the 10th of the following month of the tax period.
