Understanding Post-Sale Discounts & Credit Notes Under GST.

A Practical Guide Based on CBIC Circular No. 251/08/2025-GST (Dated 12 September 2025) - Below is a well-structured article based on Circular No. 251/08/2025-GST, written in a clear, practical, and example-rich manner for easy understanding by taxpayers, businesses, and professionals.

The Central Board of Indirect Taxes & Customs (CBIC) has issued Circular No. 251/08/2025-GST to clarify long-pending doubts surrounding secondary discounts, post-sale discounts, financial/ commercial credit notes, and their GST implications.

This article breaks down the circular into simple language, supported with practical business examples so that manufacturers, distributors, dealers, and tax professionals can apply the law correctly.

1. Input Tax Credit (ITC) When Supplier Issues Financial/Commercial Credit Notes

CBIC Clarification

If a supplier issues financial or commercial credit noteswithout GST (i.e., GST liability is not reduced), the recipient is NOT required to reverse ITC, even if the payment made is less than the original invoice value.

Why?

• Section 16(1) allows ITC of tax charged on supply.
• When a credit note is issued without GST, the original tax charged remains unchanged.
• Therefore, no ITC reversal is required.

Exhibit 1: Simple Practical Example

Scenario:
A manufacturer issues an invoice:

• Goods value: Rs. 1,00,000
• GST @18%: Rs. 18,000
• Total invoice amount: Rs. 1,18,000

Later, the manufacturer issues a commercial credit note of Rs.10,000 (without GST) for achieving quarterly targets.

Dealer pays: Rs.1,08,000 instead of Rs.1,18,000.

Effect on ITC:

• Dealer can still claim full ITC of Rs.18,000.
• No reversal is needed because the GST amount was not reduced.

Correct Treatment:

• Supplier cannot reduce tax liability.
• Recipient need not reverse ITC.

2. Whether a Post-Sale Discount is Consideration for Dealer’s Supply to End Customer

This is one of the most misunderstood areas in GST.

CBIC Clarification

There are two separate sale transactions:

1. Manufacturer,  Dealer
2. Dealer,  End customer

If there is no agreement between manufacturer & end customer, the post-sale discount given to the dealer is NOT a consideration for “inducement” of the dealer’s sale to the customer.

This discount reduces pricing only, not a payment for extra services.

Exhibit 2: Normal Business Discount

Scenario:

• Manufacturer sells goods to a dealer for Rs.10,000.
• Dealer is free to sell to any customer at any price.
• Manufacturer later gives a post-sale discount of Rs.1,000 (commercial credit note) to increase market competitiveness.

Is this discount a consideration or inducement?

No. The discount only reduces the effective sale price between manufacturer and dealer.

GST Impact:

• Discount is not “consideration” for the dealer’s sale.
• No GST is payable by the dealer on this discount.

However, one important exception exists…

If the manufacturer has an agreement with the end customer to offer a specific discounted price, and instructs the dealer accordingly, then:

The discount becomes part of the consideration because it acts as an inducement to the dealer for selling to the customer at that lower price.

Exhibit 3: Discount Linked to a Customer Commitment

Scenario:

• Manufacturer enters into an agreement with Tata Motors to supply parts at Rs.900 each.
• Dealer supplies the goods to Tata Motors (end customer).
• Manufacturer compensates dealer with a Rs.100 discount per unit through a commercial credit note.

GST Impact:

• This discount is an inducement for the dealer’s supply to Tata Motors.
• Hence, the discount must be added to the dealer’s consideration for GST purposes.

3. Are Post-Sale Discounts Consideration for Promotional Activities?

Dealers often perform promotional activities such as local marketing, banners, discount campaigns, etc. The question is:

Is the post-sale discount a payment for such promotional services?

CBIC Clarification

Usually, No.

If the promotional activities are done to increase the dealer’s own sales in goods he owns, then:

• Post-sale discount is NOT consideration for services.
• No separate GST applies.

Exhibit 4: Normal Promotional Activities (Not Taxable)

Scenario:
Dealer runs a Diwali sale and advertises the manufacturer’s brand. Manufacturer gives a post-sale discount of Rs.50 per item.

GST Impact:

• Dealer is not rendering a service to the manufacturer.
• No GST on this discount.

However — GST WILL APPLY when promotional services are specifically contracted.

If the dealer performs specific, agreed marketing services for the manufacturer, e.g.:

• Advertising campaigns
• Market surveys
• Co-branding
• Store branding
• Special display arrangements
• Customer support helpdesks
• Promotional events

…AND the agreement specifies a separate consideration, then:

This is a taxable supply of service by the dealer.

Exhibit 5: Specific Marketing Services (Taxable)

Scenario:
Manufacturer signs a contract with dealer:

• Dealer must run a co-branded hoarding campaign.
• Manufacturer will pay Rs. 2,00,000 as marketing support.

GST Impact:

• Dealer must raise a GST invoice on manufacturer for Rs. 2,00,000 + GST.
• This is separate from post-sale discounts.

Summary Table for Easy Understanding

Conclusion

Circular No. 251/08/2025-GST settles long-standing confusion on secondary discounts by laying down clear principles:

• Not all post-sale discounts are taxable.
• Not all promotional activities amount to a taxable service.
• ITC need not be reversed when credit notes are issued without GST.
• Only discounts tied to specific inducements or contracted services attract GST.

These clarifications restore ease of doing business and prevent unnecessary litigation.
