Question 21: There are cases in which the ECO does not provide invoicing solution to the seller. In such cases, invoice is generated by the seller and received by the buyer without ECO getting to know about it. The payment flows through the ECO. In such cases, on what value is TCS to be collected? Can TCS be collected on the entire value of the transaction?
Answer: Section 52(1) of the CGST Act, 2017 mandates that TCS is to be collected on the net taxable value of such supplies in respect of which the ECO collects the consideration. The amount collected should be duly reported in GSTR-8 and remitted to the Government. Any such amount collected will be available to the concerned supplier as credit in his electronic cash ledger.

Question 22: GST requires a dealer to maintain a consecutive serial number for invoices. If we are supplying from multiple locations, do we need to centrally maintain the invoice numbers serially?
Answer: Section 46 of the CGST Rules, 2017 provides that invoice may have “a consecutive serial number not exceeding sixteen characters, in one or multiple series, containing alphabets or numerals or special characters hyphen or dash and slash symbolised as “-” and “/” respectively, and any combination thereof, unique for a financial year”. Therefore, a supplier can have multiple series for the same year, so long as the same series is not used across financial years. Therefore, you may have a different invoice series for each location having consecutive serial numbers running across that series.

Question 23: There are sellers who are selling exempted or zero-tax goods like books through ECOs. Will marketplaces be required to collect TCS on such supplies?
Answer: As per Section 52(1) of the CGST Act, 2017 TCS is to be collected on “the net value of taxable supplies” made through an ECO. When the supply itself is not taxable, the question of TCS does not arise.

Question 24: I am a supplier selling my own products through a web site hosted by me. Do I fall under the definition of an “electronic commerce operator”? Am I required to collect TCS on such supplies?
Answer: As per the definitions in Section 2 (44) and 2(45) of the CGST Act, 2017, you will come under the definition of an “electronic commerce operator”. However, according to Section 52 of the Act ibid, TCS is required to be collected on the net value of taxable supplies made through it by other suppliers where the consideration is to be collected by the ECO. In cases where someone is selling their own products through a website, there is no requirement to collect tax at source as per the provisions of this Section. These transactions will be liable to GST at the prevailing rates.

Question 25: We purchase goods from different vendors and are selling them on our website under our own billing. Is TCS required to be collected on such supplies?
Answer: No. According to Section 52 of the CGST Act, 2017, TCS is required to be collected on the net value of taxable supplies made through it by other suppliers where the consideration is to be collected by the ECO. In this case, there are two transactions - where you purchase the goods from the vendors, and where you sell it through your website. For the first transaction, GST is leviable, and will need to be paid to your vendor, on which credit is available for you. The second transaction is a supply on your own account, and not by other suppliers and there is no requirement to collect tax at source. The transaction will attract GST at the prevailing rates.
Note: Reference to CGST Act, 2017 includes reference to SGST Act, 2017 and UTGST Act, 2017 also.
