Electronic Commerce Transactions: formula sheet

Full chapter guide

Key formulas

Electronic commerce: Supply of goods or services or both, including digital products, over a digital or electronic network; Section 2(44). The supply must take place over the network. Merely displaying information is not enough.
Electronic commerce operator: Person who owns OR operates OR manages a digital or electronic facility or platform for electronic commerce; Section 2(45). Any one of the three activities makes a person an ECO. Ownership of the goods sold is not required, and the definition does not need third-party sellers.
Supplier: Person supplying goods or services or both + agent acting as such on behalf of the supplier; Section 2(105). On a marketplace, the seller is the supplier, not the platform, unless the platform itself sells.
Role test: Platform role = ECO; selling role = supplier; one entity can hold both roles; Decide the role separately for each transaction. Registration status is then checked person by person.
TCS amount: TCS = Rate × Net value of taxable supplies; Rate is as notified, capped at 1% by Section 52. Compute supplier-wise, month-wise.
Net value of taxable supplies: Net value = Taxable supplies by registered persons through the platform in the month − Taxable supplies returned in the month − Services on which operator pays tax under Section 9(5); Use value excluding GST. Exempt, nil-rated and non-taxable supplies are not part of taxable supplies.
Split of TCS: Intra-State: CGST + SGST/UTGST, each half of the rate. Inter-State: IGST at the full rate; For a 0.5% rate: 0.25% + 0.25%, or 0.5% IGST. Follow the supply's place of supply and supplier's location.
Payment and statement timeline: Pay the TCS and file GSTR-8 by the 10th of the following month; This is a single deadline. TCS is credited to the supplier's electronic cash ledger.
Condition for collection: TCS applies only where the operator collects the consideration for the supply; If the customer pays the supplier directly, no TCS on that supply.
TDS vs TCS: TDS (Section 51): by notified deductors on payment to supplier. TCS (Section 52): by e-commerce operators on collection from customer; Both are credited to the supplier's electronic cash ledger and are not additional tax.
Who pays GST: Notified service + supplied through ECO + conditions of that entry met ⇒ ECO pays GST (treated as supplier); All three tests must be met. If any one fails, the supplier pays tax as usual and the ECO deals with TCS.
Liability of ECO under 9(5): GST payable by ECO = value of the notified service × applicable GST rate; The ECO pays on the value of the notified service itself, not on its own commission. Use the rate stated in the question.
Scope of Section 9(5): Intra-State supplies under Section 9(5) CGST Act; inter-State supplies under Section 5(5) IGST Act; The notification must name the service. Supplier-status conditions apply only to specific entries (for example accommodation and housekeeping by unregistered persons). Passenger transport is covered only as the notified entry and its exclusions state. Restaurant service has notified exclusions, and a restaurant required to be registered is outside it.
ECO without physical presence: Provisos to Section 5(5) IGST Act: representative in taxable territory pays tax; if none, ECO appoints a person in taxable territory; This is an IGST Act rule for inter-State supplies. Do not apply it to an intra-State supply under Section 9(5) CGST.
Link with Section 52: TCS base = net value of taxable supplies through ECO, excluding supplies on which ECO pays tax under 9(5); A supply taxed in the ECO's hands under 9(5) is not also subject to TCS. Other supplies through the ECO remain in the TCS base.

Quick revision

An electronic commerce operator owns, operates or manages a digital or electronic facility or platform for supplies of goods or services.
The supplier is the person who supplies goods or services through the platform; the operator is a different role.
TCS under section 52 is on the net value of taxable supplies made through the operator by registered suppliers (other than the operator), as per the law.
Net value means the aggregate value of taxable supplies (exempt and nil-rated supplies excluded) less taxable supplies returned to the suppliers.
The operator collects TCS from the amount it pays to the supplier and deposits it with the government.
Section 9(5) makes the operator liable to pay tax on notified services as if it were the supplier.
Which services fall under section 9(5) is decided by notification, so check the current list.
Under TCS the supplier remains liable for the tax; under section 9(5) the operator pays the tax on the notified services as if it were the supplier.
The operator that collects TCS furnishes a monthly statement (GSTR-8) by the 10th of the next month.
Under section 52(7), the amount collected is credited to the electronic cash ledger of the supplier on the basis of the operator's statement under section 52(4).
Under section 24(x), e-commerce operators required to collect tax at source under section 52 must register compulsorily, with no threshold exemption. They file the GSTR-8 statement. Suppliers' registration is covered separately in section 24(ix).
In every case, first identify the parties, then the type of supply, then the rule.
Always check conditions, thresholds and rates in the current official text before you answer.

Common mistakes

Calling the platform the supplier for every sale. Fix: Ask who makes the supply. The seller is the supplier. The platform is the supplier only for its own goods or services.
Saying an ECO must own the goods sold. Fix: The definition needs only owning, operating or managing the platform. Ownership of goods is irrelevant.
Applying TCS on gross sales including exempt and nil-rated supplies. Fix: Net value covers only taxable supplies. Remove exempt, nil-rated and non-taxable items before computing.
Forgetting to deduct supplies returned during the month. Fix: Always subtract the taxable value of returns made in the same month before applying the rate.
Treating every service sold through an app as covered by Section 9(5). Fix: Only services named in the notification are covered. Match the service to the list first.
Applying TCS on a supply on which the ECO already pays tax under Section 9(5). Fix: Exclude such supplies from the TCS base. The ECO pays tax on them as the supplier.

Exam tips

In case-scenario MCQs, underline the verbs: owns, operates, manages, supplies. They tell you the role directly.
Write the definition first, then apply it. Examiners award marks for the provision and the facts before the conclusion.
Always check whether the same entity plays two roles. This is a favourite trap.
Note the registration status of the supplier in the facts. It decides which later provision applies.
Quote section numbers only for the definitions you know well. Use plain words for the rest.
Write the provision first: Section 52 of the CGST Act, operator collects consideration, rate as notified and up to 1%. Then apply facts. This gives marks in the provision-facts-conclusion pattern.
In numericals, show the net value computation as a small list: add taxable supplies, subtract returns, remove exclusions. Marks are often given for the net value before the rate is applied.
Watch for traps in case scenarios: exempt supplies, Section 9(5) services, direct payments to the supplier, and returns in the same month.
