GST suppliers giving post-sale discount have to take undertaking from clients: CBIC

Suppliers giving post-sale discounts through credit notes under GST will have to ensure that the client gives an undertaking or a CA certificate stating that the ITC availed on the discount value has been reversed, the CBIC has said.

Currently, there is no mechanism to track whether the Input Tax Credit (ITC) on such discounts has been reversed or not.

Till the time a functionality is made available on the common portal to enable the suppliers as well as the tax officers to verify the reversal, the supplier may procure a certificate from the recipient of the supply, issued by the Chartered Accountant (CA) or the Cost Accountant (CMA), certifying that the recipient has made the required proportionate reversal of ITC at his end in respect of such credit note issued by the supplier.
