Near-expiry and expired medicines are one of the biggest stock problems for chemists and pharma distributors. Stock that is not sold in time blocks your money, and returning it to the supplier has GST consequences that many stores get wrong. This guide explains the two ways GST allows you to return time-expired medicines, who issues the credit note, what happens to your input tax credit (ITC) and which time limits matter.
Catch near-expiry stock early
Every strip, bottle and vial carries a batch number and an expiry date. Recording both at the time of purchase is the only reliable way to find stock that is close to expiry while your distributor will still take it back. Distributors usually accept expiry returns only within their own return window, so the earlier you spot a slow-moving batch, the more of its value you recover.
Manual shelf checks miss things in a busy store. ValueSoft Pharmacy Retail Billing Software gives expiry alerts and near-expiry reports by batch, so you can pull those batches off the shelf and plan the return in time. Distributors get the same with ValueSoft Pharma Wholesaler & Distributor Software, which tracks batch-wise stock, expiry and breakage.
Two ways to return expired medicines under GST
CBIC Circular No. 72/46/2018-GST, dated 26 October 2018, deals with exactly this situation. A retailer or wholesaler sending back time-expired medicines can follow either of two methods.
Method 1: Treat the return as a fresh sale
- A regular GST-registered retailer or wholesaler issues a tax invoice for the goods it sends back and charges GST on it. The value can be taken from the original purchase invoice.
- The wholesaler or manufacturer receiving the goods can claim ITC on that invoice, subject to the normal conditions of Section 16 of the CGST Act.
- A composition taxpayer returns the goods on a bill of supply and pays tax at the composition rate, so the receiver gets no ITC. An unregistered seller can use any commercial document, without charging tax.
Method 2: The supplier issues a credit note
- The retailer sends the goods back on a delivery challan, and the original supplier issues a credit note under Section 34 of the CGST Act.
- The supplier can reduce its GST on that credit note only if it is declared within the time limit (see below) and the retailer has not claimed the ITC, or has reversed it. Since 1 October 2025 this condition, that the buyer reverses the ITC, is written into Section 34(2) itself.
- If the time limit has passed, the supplier can still issue a credit note to settle the money, but it cannot reduce its tax on it.
Agree with each distributor which method they follow, because it decides who issues which document and who adjusts the tax.
Time limits for credit notes
A supplier that wants to reduce its tax through a credit note must declare it in its return no later than 30 November following the end of the financial year in which the original sale was made, or the date it files the annual return for that year, if that is earlier. For medicines sold between April 2025 and March 2026, for example, the credit note has to be declared by 30 November 2026 at the latest.
The supplier reports the credit note in GSTR-1 and adjusts its tax in GSTR-3B. As the buyer, you see it in your GSTR-2B and must reduce your ITC by the same amount in GSTR-3B.
When you must reverse ITC on expired stock
Not every expired strip goes back to the supplier. If you destroy or write off expired medicines yourself, Section 17(5)(h) of the CGST Act blocks the ITC on goods that are written off or destroyed, so you must reverse the ITC you took when you bought them.
For example, you bought medicines worth ₹10,000 plus ₹500 GST at 5% and claimed the ₹500 as ITC. If they expire and you destroy them, reverse the ₹500 in your GSTR-3B. If you keep the ITC, the department can recover it with interest, and penalties can follow.
The same applies to a manufacturer that destroys returned medicines: it reverses the ITC on those goods. For large write-offs, or returns that cross financial years, speak to your CA.
Checklist for expiry returns and write-offs
- Check near-expiry stock every month with a batch-wise expiry report.
- Agree the return method with each distributor: your tax invoice (Method 1) or their credit note (Method 2).
- Send the goods with the right document: a tax invoice for Method 1, a delivery challan for Method 2.
- Collect the credit note under Method 2 and check that it appears in your GSTR-2B.
- Reverse ITC where needed: on credit notes you receive, and on stock you destroy yourself.
- Keep records of every return and destruction (batches, quantities, dates) for audits.

Frequently asked questions
Who issues the credit note when a chemist returns expired medicines?
Under the credit note method, the original supplier (the distributor or wholesaler) issues the credit note under Section 34 of the CGST Act, and the chemist sends the goods back on a delivery challan. Alternatively, a regular GST-registered chemist can treat the return as a fresh sale and issue a tax invoice to the distributor, as CBIC Circular 72/46/2018-GST explains.
What is the time limit for a GST credit note on returned medicines?
To reduce its tax, the supplier must declare the credit note by 30 November following the end of the financial year of the original sale, or by the date it files the annual return for that year, whichever is earlier. A credit note issued later still settles the money, but the supplier cannot reduce its GST on it.
Do I have to reverse ITC on expired medicines I destroy myself?
Yes. Section 17(5)(h) of the CGST Act blocks input tax credit on goods that are written off or destroyed, so reverse the ITC you claimed on those medicines in your GSTR-3B.
