Section 52 tax collection at source: collection, credit and mismatch disputes
A collection mechanism that produces a three way reconciliation between the platform, the seller and the portal.
Section 52 requires an electronic commerce operator to collect tax at source at the notified rate on the net value of taxable supplies made through it by other suppliers where the consideration is to be collected by the operator. Net value is the aggregate value of taxable supplies of goods or services made through the operator by all registered persons, other than notified services, reduced by the value of supplies returned. The amount is paid by the tenth of the following month, reported in GSTR-8, and credited to the supplier's electronic cash ledger.
The computation
The base is the net value of taxable supplies, which excludes supplies notified under Section 9(5) and is reduced by the value of supplies returned in the same month.
The rate is as notified and was reduced from the original rate; verify the rate applicable to the period.
It applies only where the consideration is collected by the operator. Where the seller collects directly, the obligation does not arise.
Exempt supplies are outside the base, and the classification of exempt items in the catalogue therefore has a TCS consequence.
The reconciliation, and where it breaks
The operator files GSTR-8. The supplier sees the TCS credit and claims it in its return, and the amount is credited to the cash ledger.
The mismatches that recur: returns and cancellations processed in a different month from the sale, so the net value differs between the platform and the seller.
Value differences where the platform reports the gross order value and the seller reports the invoice value net of discounts.
State allocation differences, where the platform allocates to the warehouse state and the seller to its registered state.
Timing differences at month end, where the sale and the collection fall in different periods.
Each of these produces a notice to the seller for under reported turnover, and the answer is the reconciliation, not an argument.
What each side should do
For the platform: reconcile GSTR-8 to the transaction ledger monthly, and give sellers a downloadable statement matching what has been reported.
For the seller: reconcile the platform statement to your own invoices and to the TCS credit in the cash ledger every month, and claim the credit in the same period.
For both: agree the treatment of returns, cancellations, discounts and shipping charges in the onboarding agreement, so the reporting is consistent from the start.
For the seller: remember that TCS credit sits in the cash ledger and must be claimed; unclaimed TCS credit accumulates unnoticed and is refundable.
What to do on Monday
Reconcile the platform statement, your invoices and the TCS credit in the cash ledger every month.
Agree the treatment of returns, discounts and shipping in the platform onboarding agreement.
Claim TCS credit in the same period; unclaimed credit accumulates silently.
Review the cash ledger annually and claim a refund of accumulated TCS.

Write to the GST practiceQuestions we are asked on this
Is TCS applicable to Section 9(5) supplies?
No. Those supplies are excluded from the net value because the operator pays the tax as deemed supplier.
Can TCS credit be used to pay tax?
It is credited to the electronic cash ledger and can be used like any cash ledger balance, once claimed.
What if the platform reports a higher value?
Reconcile and take it up with the platform. A notice to the seller for turnover under reporting is answered with the reconciliation.
Is TCS refundable if unused?
A cash ledger balance is refundable under Section 49(6) with Section 54. Review it annually.
Does TCS apply to exempt supplies?
No. The base is taxable supplies.
