Discounts such as sales discounts, seasonal discounts and promotional schemes are very common in business. Under GST, a discount itself is not a separate good or service. Because of this, there is no independent HSN code only for discounts.

What is the HSN Code for Discounts?

In practice, there is no unique HSN code for discounts. Discounts are:

Part of the pricing of the main goods or services sold
Shown as a reduction in value on the invoice
Linked to the HSN code of the underlying product or service

So, when you give a discount on a product with a particular HSN, the discount also follows the same HSN and GST rate as that product.

How Sales Discounts Are Classified Under HSN Code?

Sales discounts can be:

Shown upfront on the invoice as trade discount
Given later as a credit note, such as year end rebate or turnover discount

In both cases:

You do not classify discount under a separate heading
You apply the same HSN and rate that applied to the original supply
In credit notes, you refer to the original invoice and HSN code

Therefore, discount is more of a value adjustment and not a separate HSN classification.

Understanding Seasonal and Promo Discounts Under HSN

Seasonal discounts and promo offers like festival sales, combo offers or buy one get one schemes also follow the same rule.

Important points:

The main product and free product, if any, are classified under their own HSN
GST is calculated on the taxable value after discount, subject to GST rules
There is no separate discount HSN to be shown anywhere in returns

You must ensure the discount conditions are clearly recorded so that GST treatment is correct.

GST and Its Impact on Discount Classification

GST law gives special rules for discounts:

Discounts given before or at the time of supply and shown on invoice can be reduced from taxable value
Post supply discounts can reduce value if they are agreed in advance and supported by credit notes and agreement

In all cases, the HSN stays the same as the underlying product. Only value changes. Wrong handling of discounts can affect tax liability and input tax credit.

Discount HSN Code Classification and GST Rates

Here are some commonly used HSN codes and GST rates for this category

4 Digit HSN Code Classification

HSN Code	HSN/SAC Code Title	Description	Old GST Rate	New GST Rate
NA	Not Applicable	Discount has no standalone 4 digit HSN. Use the 4 digit HSN of the underlying product or service and show discount as a value deduction.

8 Digit HSN Code Classification

HSN4 Code	HSN8 Code	HSN Code Title	Description	GST Rate
NA	NA	Not Applicable	Discount has no standalone 8 digit HSN. Use the same HSN as the original invoice item, including in credit notes.

* GST rates may vary based on the latest GST notifications and amendments

Is there a separate HSN code for sales discounts?

No, there is no separate HSN for discounts. Discounts simply reduce the taxable value of the goods or services supplied.

Which HSN code should I use for seasonal or promo discounts?

You should use the same HSN code as the product or service on which the discount is given.

Does GST apply on discounts?

GST is calculated on the net value after allowable discounts. So the tax amount reduces when eligible discounts are given.

How are discounts shown in GST returns?

Discounts given on the invoice are already reflected in the taxable value. Post supply discounts are reported through credit notes linked to original invoices.

Can discounts for different products have different HSN codes?

Yes, but only because the underlying products have different HSNs. The discount itself does not carry a separate HSN.
