The three cases, so they do not get mixed up
| What happened | Credit note? | What to do |
|---|---|---|
| The tax authority rejected it | No | Issue a new invoice referencing it |
| The customer rejected it | Yes | Credit note, then a new invoice |
| It simply came out wrong | Yes | Return, amount or wording corrected |
Who rejected it determines which document applies.
Case 1 · The tax authority rejected it
Here there is nothing to void, because the document never had any validity. The regulation is explicit: when the Ministry of Finance's confirmation message is a rejection, for tax purposes the corresponding credit or debit note must not be made. What applies is issuing a new document immediately, stating which one it replaces. What a rejection means.
Case 2 · The customer rejected it
If the recipient rejects the invoice, wholly or partly, and the tax authority approves that rejection, the recipient returns the message to the issuer. From there the issuer has two obligations, in this order:
-
Issue the credit note
To modify or void, wholly or partly, the accounting effect of the invoice. It has to reference the original document by its key.
-
Then issue the corrected invoice
With the next number in the series, and the correction actually made — otherwise the recipient rejects it again.
Case 3 · It simply came out wrong
A return, a later discount, a wrong amount, a mistyped description. The invoice was accepted and is valid, so it is corrected with a credit note — partial if only part of it is affected, total if the whole thing is.
What never happens
- The number is not reused. Not after a rejection, not after a credit note. The sequence moves forward and never goes back.
- The original is not modified. An electronic document is unalterable by design: that is what the signature is for.
- Nothing is deleted. Voided documents are kept for five years too.
The right document for what happened
A rejected document offers a replacement, not a credit note. An accepted one offers the note, with the reference already filled in.
See how it worksAbout this article. The prohibition on issuing a credit note over a rejected document, and the obligations after a customer's rejection, come from the Electronic Documents Regulation; the reference requirements, from the version 4.4 annex.
