Statutory text
Bare law
(1) Where one or more tax invoices have been issued for supply of any goods or services or both and the taxable value or tax charged in that tax invoice is found to exceed the taxable value or tax payable in respect of such supply, or where the goods supplied are returned by the recipient, or where goods or services or both supplied are found to be deficient, the registered person, who has supplied such goods or services or both, may issue to the recipient one or more credit notes for supplies made in a financial year containing such particulars as may be prescribed.
(2) Any registered person who issues a credit note in relation to a supply of goods or services or both shall declare the details of such credit note in the return for the month during which such credit note has been issued but not later than the thirtieth day of November following the end of the financial year in which such supply was made, or the date of furnishing of the relevant annual return, whichever is earlier, and the tax liability shall be adjusted in such manner as may be prescribed: Provided that no reduction in output tax liability of the supplier shall be permitted, if the–– (i) input tax credit as is attributable to such a credit note, if availed, has not been reversed by the recipient, where such recipient is a registered person; or (ii) incidence of tax on such supply has been passed on to any other person, in other cases.
(3) Where one or more tax invoices have been issued for supply of any goods or services or both and the taxable value or tax charged in that tax invoice is found to be less than the taxable value or tax payable in respect of such supply, the registered person, who has supplied such goods or services or both, shall issue to the recipient one or more debit notes for supplies made in a financial year containing such particulars as may be prescribed.
(4) Any registered person who issues a debit note in relation to a supply of goods or services or both shall declare the details of such debit note in the return for the month during which such debit note has been issued and the tax liability shall be adjusted in such manner as may be prescribed.
Explanation.––For the purposes of this Act, the expression “debit note” shall include a supplementary invoice.
Introduction
Credit notes address overcharged taxable value or tax, returned goods or deficient supplies. Debit notes address undercharged value or tax. For a credit note, the statutory reporting cutoff is 30 November after the supply financial year or the relevant annual return filing date, whichever is earlier. The consolidated Act includes a 2025 condition limiting output-tax reduction where recipient ITC has not been reversed or tax incidence was passed on.
Key takeaways
Credit note for excess or returns
A registered supplier may issue one or more credit notes for a financial year's supplies when value or tax was too high, goods were returned or the supply was deficient.
Debit note for short charge
Where an invoice understates taxable value or tax, the registered supplier issues one or more debit notes and reports them in the return.
Credit-note tax adjustment has a cutoff
Report the credit note by 30 November following the supply year or relevant annual return filing, whichever is earlier, to adjust liability under subsection (2).
Recipient ITC or tax incidence may block reduction
The 2025 proviso denies supplier output-tax reduction if the registered recipient has not reversed attributable ITC, or, in other cases, tax incidence was passed to another person.
Identify credit or debit direction
Compare invoice value and tax with the correct supply value and tax. Excess, returned goods or deficient supply point to a credit note; a short charge points to a debit note. Preserve evidence of the reason and original invoices.
Report a credit note on time
Declare it in the return for the issue month, subject to subsection (2)'s 30 November or annual-return cutoff. Tax liability adjusts only in the prescribed manner and subject to the statutory proviso.
Check the 2025 output-tax reduction condition
For a registered recipient who availed attributable ITC, verify reversal before reducing supplier output tax. In other cases, test whether tax incidence was passed on. The current proviso took effect on 1 October 2025; period-specific treatment should be reviewed.
Report debit notes
Issue the prescribed debit-note particulars and declare the note in the issue-month return. A supplementary invoice is included in the Act's debit-note expression.
Practical checklist
Do
- Match every note to the original supply and reason for adjustment.
- Track the credit-note reporting cutoff and annual-return date.
- Check recipient ITC reversal or tax-incidence evidence before output-tax reduction.
Avoid
- Use a credit note to reduce tax after the statutory reporting cutoff without legal review.
- Assume issuing a commercial credit note automatically reduces GST liability.
- Treat a debit note as a credit note in returns.
Frequently asked questions
Can one credit note cover more than one invoice?
Section 34(1) permits one or more credit notes for supplies made in a financial year, subject to prescribed particulars and reporting.
Is issuing a credit note enough to reduce GST output tax?
No. Subsection (2) imposes reporting and adjustment requirements, and its current proviso may bar reduction depending on recipient ITC reversal or tax incidence.
