Discounts are common in B2B and B2C trade. Under GST, discounts can reduce the value of supply only if certain conditions are met. Post-supply discounts require a credit note and have specific time of supply implications.
Value of Supply and Discounts: Section 15(3)
Section 15(3) of the CGST Act provides that the value of supply shall not include any discount which is given:
- Before or at the time of supply if such discount has been duly recorded in the invoice issued in respect of such supply.
- After the supply if:
- Such discount is established in terms of an agreement entered into at or before the time of supply and specifically linked to relevant invoices.
- Input tax credit as is attributable to the discount on the basis of document issued by the supplier has been reversed by the recipient of the supply.
Thus, pre-supply discounts are simply deducted from invoice value and do not attract GST.
Post-supply discounts can also reduce GST, but only if the above conditions are met.
Pre-Supply Discount
A discount given before or at the time of supply and recorded on the invoice is excluded from the taxable value. Example: A seller offers 10% trade discount on the invoice. The GST is calculated on the net amount after discount.
Post-Supply Discount
A discount given after the invoice has been issued, such as a year-end volume discount or cash discount. To exclude from GST:
- There must be a written agreement entered into before or at the time of supply.
- The discount must be linked to specific invoices.
- The recipient must reverse the input tax credit attributable to the discount.
Time of Supply for Post-Supply Discount
A post-supply discount is given through a credit note issued by the supplier. The time of supply for the credit note is the date of issue of the credit note, not the date of the original supply.
The supplier reduces output tax liability in the return for the period in which the credit note is issued. The recipient reverses ITC in the same period.
Example
Supplier sells goods worth Rs 5,00,000 plus 18% GST on 1 July. Under an agreement dated 1 January, the supplier agrees to give a 2% year-end discount on achieving sales targets. On 31 March, the target is met, and the supplier issues a credit note of Rs 10,000 plus Rs 1,800 GST.
- Supplier reduces output tax by Rs 1,800 in March return.
- Recipient reverses ITC of Rs 1,800 in March return.
- Time of supply for the credit note is 31 March.
Conditional vs Unconditional Discounts
A conditional discount, such as prompt payment discount, may not be known at the time of supply. If the condition is fulfilled later, a credit note can be issued. The conditions under Section 15(3) still apply.
An unconditional discount known upfront should be recorded on the invoice and deducted from value.
Impact on Input Tax Credit
If the recipient does not reverse ITC, the supplier cannot reduce output tax. The supplier may still issue a credit note, but the tax reduction will be disallowed, leading to a demand.
Practical Compliance
- Maintain discount agreements signed before supply.
- Link discounts to specific invoices in the agreement or records.
- Issue credit notes timely and link to original invoices.
- Reconcile with recipients to ensure ITC reversal.
- Report credit notes in GSTR-1 and adjust in GSTR-3B.
Common Mistakes
- Giving post-supply discount without a written agreement.
- Not linking discount to specific invoices.
- Not ensuring recipient reverses ITC.
- Issuing credit note after the September return time limit for output tax reduction.
