GST Credit Note Generator Formula & Calculation

A GST credit note reverses all or part of a tax invoice you already issued. Each line is calculated exactly like an invoice line — quantity times rate gives the taxable value being credited, and that line's GST% gives the tax being credited — so a full cancellation simply repeats every line of the original invoice.

For intra-state supply the tax credited is split equally into CGST and SGST; for inter-state supply it is shown as IGST. The credit note must follow the original invoice's supply type and rates, otherwise the tax you reverse won't match the tax you charged.

Example: Cancelling a ₹15,000 web design line at 18% GST gives a taxable credit of ₹15,000, tax credit of ₹2,700 (CGST ₹1,350 + SGST ₹1,350) and a total credit of ₹17,700.

Key Factors That Affect Your Result

1. Match the original invoice — Quote the original invoice number and date, and reuse its GST rates and supply type; a mismatch makes the credit note hard to reconcile in GSTR-1 and the customer's ITC reversal.
2. Deadline for the tax reduction — To reduce your output tax, the credit note generally has to be issued and declared by 30 November after the end of the financial year of the original supply (or the annual return date, if earlier). Later notes can be issued but won't reduce your tax.
3. Customer's ITC — A GST-registered customer who claimed input tax credit on the original invoice must reverse the matching credit, so send them the credit note promptly.
4. E-invoice cases — If the original was an e-invoice, check whether it can still be cancelled on the portal; once that window has passed, a credit note is the correct route.
