Credit Notes and Invoice Corrections in Malta

Sooner or later you will send an invoice that turns out to be wrong: a returned item, an overcharge, a discount agreed after the fact. In Malta you do not fix this by deleting or editing the original invoice; you issue a credit note. Here is how credit notes work, when to use them, and how they affect your VAT.

What is a credit note?

A credit note, sometimes called a credit memo, is a document that reduces the amount of a previously issued invoice. It is effectively a negative invoice: it cancels all or part of the original sale and adjusts the VAT that was charged. Because it changes your output VAT, it is a formal accounting document, not an informal note to the client.

When you need to issue a credit note

• The customer returns goods or cancels part of an order;
• You overcharged, or applied the wrong price or VAT rate;
• You agree a discount or rebate after invoicing;
• A service was not delivered as invoiced;
• An invoice was issued in error or duplicated.

What a credit note must show

A credit note must be clearly identifiable as such and, most importantly, cross-referenced to the original invoice. It should include:

• The label "credit note" and its own sequential number;
• The date of issue;
• A reference to the original invoice number and date;
• Your details and the customer's details, as on the invoice;
• The amount being credited and the VAT adjusted, per rate;
• The reason for the credit.

The golden rule: never delete an issued invoice

Once an invoice has been issued and recorded, deleting it or quietly editing the figures breaks your sequential numbering and your VAT trail, which is exactly what an inspection flags. The correct fix is always to issue a credit note that references the original, then, if needed, a fresh corrected invoice. This keeps an honest, auditable history of what happened. See our compliant invoice guide on why gap-free numbering matters.

How a credit note affects your VAT return

A credit note reduces the output VAT you previously declared on the sale, and correspondingly reduces the input VAT your customer reclaimed. You account for it in the VAT period in which it is issued. Keeping credit notes tied to their invoices makes your quarterly VAT return straightforward and your records consistent.

What about debit notes?

A debit note does the opposite: it increases the value of a supply, for example when you undercharged. Like credit notes, debit notes must reference the original invoice and adjust the VAT accordingly. In practice credit notes are far more common.
