Introduction
Volume discounts and turnover rebates are standard commercial tools used by manufacturers and suppliers to incentivise dealers, distributors, and large customers. These discounts are typically agreed upfront and passed on after the supply has been made, often through credit notes at the end of a quarter or financial year. The critical question is: Can these post-sale discounts be excluded from the taxable value for GST purposes?
The answer is yes, but only if the conditions under Section 15(3)(b) of the CGST Act, 2017 are satisfied. The CBIC has recently issued Circular No. 251/08/2025-GST to provide much-needed clarity on this issue.
Legal Framework: Section 15(3)(b) of the CGST Act, 2017
Exclusion of Post-Supply Discounts
Section 15(3)(b) provides that the value of supply shall not include any discount given after the supply has been effected if:
- The discount is established in terms of an agreement entered into at or before the time of supply and specifically linked to relevant invoices.
- The input tax credit attributable to the discount has been reversed by the recipient of the supply.
The CBIC Circular No. 251/08/2025-GST
The CBIC issued Circular No. 251/08/2025-GST dated 12th September 2025, providing clarity on the GST implications of secondary or post-sale discounts. The circular clarified that where a supplier issues a financial or commercial credit note for a post-sale discount, the recipient is not required to reverse ITC if the discount is a pure price reduction without any service element.
However, where the dealer explicitly undertakes promotional services under a contractual agreement — such as co-branding, advertising campaigns, or sales drives — GST is applicable on such services.
Conditions for Exclusion from Taxable Value
Agreement Before Supply
The discount must be established in an agreement entered into at or before the time of supply. The agreement should clearly specify the discount structure, the targets, and the method of calculation.
Invoice Linkage
The discount must be specifically linked to relevant invoices. This means the credit note must reference the original invoices to which the discount relates. However, the CBIC has recently eased this requirement for FMCG companies dealing with product returns and discounts.
ITC Reversal by Recipient
Where the discount is a pure price reduction and the supplier reduces the taxable value, the recipient must reverse the proportionate ITC. The CBIC Circular No. 251/08/2025-GST has clarified the circumstances under which ITC reversal is required.
Practical Implications
Credit Note Mechanism
The supplier issues a credit note under Section 34 of the CGST Act for the post-sale discount. The credit note reduces the taxable value and the tax liability of the supplier. The supplier can adjust the GST liability in the return for the period in which the credit note is issued.
ITC Adjustment by Recipient
The recipient adjusts the ITC in their electronic credit ledger. Where the discount is a pure price reduction, the recipient must reverse the proportionate ITC. Where the discount is consideration for promotional services, the recipient claims ITC on the GST charged by the supplier.
GSTR-1 Reporting
The supplier must report the credit note in Table 9B of GSTR-1 for the period in which it is issued.
Common Types of Volume Discounts and Rebates
- Volume-Based Discounts: Discounts based on the quantity purchased over a period.
- Turnover Rebates: Rebates based on the total turnover achieved by the dealer.
- Payment Target Discounts: Discounts for achieving payment targets.
- Sales Target Discounts: Discounts for achieving sales targets.
- Annual Incentives: Year-end incentives based on overall performance.
Documentation Required
- Discount Agreement: Agreement specifying the discount structure.
- Credit Note: Credit note issued under Section 34.
- Invoice Linkage: Documentation linking the credit note to relevant invoices.
- ITC Reversal Proof: Proof of ITC reversal by the recipient.
Best Practices
- Document the Agreement: Ensure the discount agreement is in place before supply.
- Issue Proper Credit Notes: Issue credit notes that comply with Section 34.
- Ensure ITC Reversal: Ensure the recipient reverses the proportionate ITC where required.
- Maintain Records: Document all discounts and credit notes.
- Review Dealer Agreements: Review dealer agreements for promotional service clauses.
- Seek Professional Assistance: For complex discount structures, seek guidance.
Conclusion
Volume discounts and turnover rebates can be excluded from the taxable value under Section 15(3)(b), provided the conditions are satisfied. The CBIC Circular No. 251/08/2025-GST has provided much-needed clarity on the treatment of post-sale discounts and the ITC reversal requirement. Proper documentation and timely compliance are essential.
