Credit Notes in Belgium: Rules, Mandatory Details, and Template

Key Takeaway: In Belgium, a credit note (note de crédit / creditnota) is the only legal way to cancel or reduce an already-issued invoice. Deleting an invoice is strictly prohibited under the Belgian VAT Code. A compliant credit note must have its own chronological sequential number, expressly reference the original invoice, include the mandatory VAT statement ("TVA à restituer à l'État dans la mesure où elle a été initialement déduite"), and be reported in VAT grid 85. In B2B, it must be transmitted electronically via Peppol UBL.

Have you sent an invoice with a calculation error, omitted a promised discount, or had a client exercise their right of withdrawal? In Belgian accounting, you can never simply delete the invoice or overwrite its number.

Belgian tax law requires continuous sequential numbering of all accounting documents. To cancel or amend an existing receivable, the only legally recognized instrument is a credit note.

This guide details the statutory obligations under Belgian Royal Decree No. 1, mandatory statements, VAT periodic return reporting (grid 85), and electronic Peppol transmission requirements.

1. When Must You Issue a Credit Note in Belgium?

Issuing a credit note is legally mandatory whenever an invoiced transaction is reduced or cancelled:

1. Clerical errors on the initial invoice: a pricing typo, an incorrect VAT rate (such as standard 21% instead of 6% renovation), or a wrong enterprise number.
2. Total order cancellation: customer contract termination, cancellation agreed between both parties, or unperformed services.
3. Goods returned: physical return of defective or unwanted products with an agreement for refund.
4. Post-invoice discount or rebate: a commercial discount granted after issuance or an early payment discount.
5. Irrecoverable debt in formal bankruptcy: customer bankruptcy confirmed by a commercial court ruling, entitling you to recover previously remitted VAT from the tax authorities.

Warning: Never delete an invoice number from your accounting records. Gaps in invoice sequences are the first trigger for tax audits in Belgium. A missing invoice incurs administrative fines ranging from €50 to €5,000 per missing document, plus disqualification of related tax deductions.

2. Mandatory Mentions on a Belgian Credit Note

Article 13 of Belgian Royal Decree No. 1 of 29 December 1992 sets out the statutory details required on every credit note issued in Belgium.

3. Mandatory VAT Statement and Periodic Return Reporting

When issuing a credit note with VAT to a taxable business customer, you are requesting a tax reimbursement from the Belgian Treasury for VAT originally declared.

To legalize this refund, Article 13, § 2 of Royal Decree No. 1 requires the following explicit statement printed on the credit note:

« TVA à restituer à l'État dans la mesure où elle a été initialement déduite. »
(Dutch: « Terug te storten btw aan de Staat in de mate waarin ze oorspronkelijk in aftrek werd gebracht. »)

This clause officially notifies your client that they must repay the input VAT they previously deducted on the original invoice. If this phrase is omitted, the seller loses the right to recover the VAT from the tax administration.

Impact on Your Belgian VAT Return (Seller)

On your next periodic VAT return:

• Grid 85 (VAT adjustments in favour of the declarant): enter the VAT amount of the credit note. This reduces total VAT owed to the state (or increases your reimbursable tax credit).
• Grid 48 (Turnover downward adjustments): report the net taxable base of the credit note for goods or services originally taxed at the standard 21% rate.

Impact on Your Business Client (Buyer)

Upon receiving the credit note:

• They must enter the reimbursed VAT amount in Grid 84 (VAT adjustments in favour of the State), remitting that tax back to the Treasury.
• They record the net deduction in Grid 87 or applicable expense adjustment accounts.

4. Electronic Credit Notes and Peppol UBL Mandate in Belgium

Under Belgium's B2B electronic invoicing mandate, credit notes exchanged between VAT-registered businesses must also be transmitted in structured electronic format via the Peppol network.

A plain PDF credit note attached to an email no longer fulfills legal B2B requirements:

• UBL Credit Note format (BIS Billing 3.0): the XML document uses the European electronic invoicing profile under UNCL1001 document type code "381" (Credit Note).
• Mandatory cac:BillingReference tag: the XML file must link to the original invoice identifier using cac:InvoiceDocumentReference, enabling automated matching in the client's accounting software.
• Positive values in UBL standard: unlike some accounting software displaying negative figures with minus signs (-), Peppol UBL requires positive numbers; the document type code 381 establishes the credit direction. You can validate your XML files directly using our free Peppol UBL validator.
