Can I amend Debit note(Purchase return) in next month's GSTR1 after receiving refund from supplier ?

Hey Prakhar, this is a classic GST debit note (purchase return) & ITC adjustment scenario—let’s break it down clearly:

Situation Recap:

• You raised a debit note/EWB for Rs. 80K (including GST).

• Supplier agrees to refund only 50% value + 50% GST.

• Supplier says you must:

  • Upload full 80K debit note in GSTR-1.

  • Reverse full ITC (on 80K) on your side.

  • Show remaining 40K as a loss.

• You are concerned you will pay GST on 40K loss from your own pocket if you follow supplier’s method.

Key GST points to note:

1. Debit note must reflect actual transaction — i.e., the value returned/refunded.

2. You cannot inflate the debit note in GSTR-1 to 80K if you are getting only 40K refund.

3. ITC reversal is required only to the extent you do not get credit/refund from supplier.

4. You should adjust your purchase return (debit note) value in GSTR-1 to reflect the actual refund value (40K + GST).

Can you amend Debit Note in next month’s GSTR-1?

• Yes, GSTR-1 allows amendment of debit notes in subsequent months (within the same financial year).

• So, if you initially uploaded 80K, you can reduce it later to 40K by amendment.

• But uploading inflated value upfront can cause unnecessary ITC reversal on your side in that month.

What should be done ideally?

• Upload debit note for the actual refund amount (50% or 40K + GST) in GSTR-1 of that month.

• No need to reverse ITC on full 80K, only on the amount not refunded.

• If situation changes, adjust by amending debit note in next month’s GSTR-1.

Who is right — Supplier or You?

• You are correct in principle — you should not show full 80K if refund is 40K.

• Supplier’s insistence to upload 80K and get you to bear extra GST from own pocket is not aligned with GST rules.

• ITC reversal should be proportionate to actual refund and debit note value.
