Credit and Debit Notes in Saudi Arabia: When and How to Correct an Invoice

An invoice may need adjustment after issue because of a return, later discount, or agreed increase. A controlled correction does not begin by erasing the original invoice; it uses a linked document that preserves the history of the change.

Credit note or debit note?

A credit note reduces the supply value or VAT, for example after returned goods or a post-sale discount. A debit note increases the value or VAT, such as an additional amount due in connection with the original supply.

Events that can require adjustment

The need for an adjustment is linked to changes addressed by Saudi VAT rules, including cancellation of a supply, a change in its nature, a change in consideration, or goods returned by the customer. Review the actual facts with your tax adviser before selecting the document.

What is the issue deadline?

ZATCA's guide to the VAT Implementing Regulations amendments states that the required note must be issued within 15 days after the end of the month in which the triggering event occurred. Record the event date immediately rather than waiting for year-end.

Reference the original invoice

ZATCA's Detailed E-Invoicing Guideline says the note must reference the original invoice and follow the type of invoice it corrects. Retain the reference number, adjustment reason, affected lines, and changed amounts.

A lower-risk correction workflow

1. Preserve the original invoice record.
2. Document the event, date, reason, and relevant approval.
3. Choose credit for a reduction or debit for an increase.
4. Reference the original invoice number clearly.
5. Review the VAT return effect with your accountant.
6. Retain the invoice and note together in a traceable record.

Important: A correction note is not an unrelated replacement invoice. Its value comes from a clear, justified link to the original document.
