Commercial credit notes under GST: when a credit note carries no tax
A commercial credit note, also called a financial credit note, is a credit note you raise without GST on it. It reduces what the buyer owes you. It does not reduce the output tax you have already paid, and the buyer does not have to reverse any input tax credit.
It is not a lesser version of a proper credit note. It is the document you are left with when a tax credit note is no longer available, and knowing which one you are raising is the difference between recovering 18% and absorbing it.
What makes a credit note commercial
A credit note under Section 34 of the CGST Act carries tax. It goes into your GSTR-1, reduces your output liability, and shows up in your buyer's GSTR-2B telling them to reverse credit.
A commercial credit note is not issued under Section 34 at all. It is an ordinary business document between two parties. There is no GST on its face, it does not appear in your GST return, and nothing happens to anyone's tax.
The GST law does not prohibit it. Circular 92/11/2019 acknowledged that suppliers may issue financial or commercial credit notes where the conditions for a tax credit note are not met.
When a commercial credit note is your only option
Two situations, and both are common.
The deadline has passed
A tax credit note can only reduce your liability if it is declared by 30 November following the end of the financial year in which the supply was made, or the date you file the annual return for that year, whichever is earlier.
A sale made in July 2026 falls in FY 2026-27. The credit note has to be declared by 30 November 2027.
After that, you can still settle with your customer. You just cannot do it with tax. The document becomes commercial.
This is the one that hurts in pharma and FMCG, where expiry returns sit at the retailer for a year before anyone deals with them. The goods come back, the money goes back, and the GST stays gone.
The discount does not meet Section 15(3)(b)
A discount given after a supply only reduces taxable value if both of these hold:
- It was established in an agreement entered into before or at the time of the supply, and can be linked to the specific invoices it relates to, and
- The input tax credit attributable to the discount has been reversed by the recipient.
Miss either one and the discount cannot reduce your taxable value. You can still pay it. You pay it through a commercial credit note.
The second condition is the one people forget is not in their control. You need your buyer to actually reverse the credit, and you need to be able to show they did.
A quarterly scheme decided in March, with nothing written before the quarter began, fails the first condition outright. No amount of paperwork afterwards rescues it.
Commercial or tax credit note
| Tax credit note | Commercial credit note | |
|---|---|---|
| Issued under | Section 34 | No specific provision |
| GST shown on it | Yes | No |
| Appears in GSTR-1 | Yes, CDNR or CDNUR | No |
| Your output tax | Reduced | Unchanged |
| Buyer reverses ITC | Yes | No |
| Deadline | 30 November following the FY | None |
The row that decides the argument with your buyer is the last but one. A commercial credit note is easier for your buyer to accept, because they keep their full input tax credit. A tax credit note costs them a reversal. That is exactly why some buyers quietly prefer the commercial route and some suppliers do not realise they are paying for that preference.
What it costs, in rupees
Take a ₹1,00,000 sale at 18%. You invoiced ₹1,18,000 and paid ₹18,000 of output tax.
The goods come back after the November cut-off. You agree to credit the customer in full.
With a tax credit note, had it been in time: you refund ₹1,18,000 and reduce your output tax by ₹18,000. The sale reverses cleanly.
With a commercial credit note, which is all you have left: you refund ₹1,18,000 and your output tax stays at ₹18,000.
That ₹18,000 is not a timing difference or a deferral. It is gone. On a 5% net margin, you have just given away the entire profit on ₹3,60,000 of sales to cover the tax on one ₹1 lakh return.
This is why "we will clear the returns at year end" is an expensive policy rather than an administrative one.
Raise it so it cannot be mistaken for a tax credit note
A commercial credit note that looks like a tax credit note is a problem for both sides. Keep it unambiguous:
- Do not show GST on it. No rate, no tax amount, no split of CGST and SGST. The value is a single figure.
- Label it plainly. "Commercial credit note" or "Financial credit note" on the face of the document.
- Keep it out of the GST series. A separate numbering series from your Section 34 credit notes, so the two never mix when someone reconciles.
- Reference the original invoice anyway. Not because GST requires it, but because your customer's ledger and yours have to agree.
- Do not put it in GSTR-1. It has no table. Software that files every credit note into CDNR will create a mismatch the portal or your buyer will find.
What your buyer should do with it
Nothing, in GST terms. There is no input tax credit to reverse, because no tax was adjusted.
In their books it reduces the amount payable to you. If they are reversing credit against a commercial credit note, they are giving up credit they are entitled to keep, and it is worth telling them.
The habit that avoids all of this
Almost every commercial credit note a distributor raises is a tax credit note that was available once and expired.
Two habits remove most of them:
Deal with returns in the month they happen. Not in the annual clean up. The deadline is generous until the goods have been sitting at a retailer for fourteen months.
Write schemes down before the period starts. A quarterly rebate agreed in writing before the quarter, referenced on the invoices it applies to, is a tax credit note later. The same rebate decided afterwards is a gift with GST on top.
The rest of what a return does to your stock, your tax and your profit is in credit notes, debit notes and sales returns under GST. If your problem is the opposite one, an invoice that charged too little, that is a debit note.
Where Dhela fits
Dhela raises credit notes against the original sales invoice, puts saleable units back into stock at the cost they left at, and carries the note into the GSTR-1 working papers in the right table with the original invoice referenced.
The reason it records a return the day the goods arrive rather than when someone gets round to the paperwork is the deadline above. A return sitting in a WhatsApp thread for eleven months is the one that turns commercial.
Dhela does not currently mark a credit note as commercial rather than tax adjusting. Every credit note it raises is a Section 34 one. If you need a commercial credit note, raise it outside Dhela and keep it in its own series.
