Correction in Vat Number for 2024 invoice

General
1

Dear Experts,

One of our customers is requesting a correction to the VAT number invoices issued in mid-2024 (June–Oct). These invoices were already cleared and submitted to ZATCA.

They’ve now stopped payment and are asking us to fix the issue.

We know we can’t edit cleared invoices, so we’re considering issuing a credit note and reissuing new invoices with the correct VAT number, dated now.(Jul-2025)

Can anyone confirm:

  • Is this process acceptable under ZATCA, even for older invoices?
  • Any official guidance or risk in doing this so late?
  • How will this affect VAT reporting and compliance?

We’re using Odoo (Phase 2 compliant).
Thanks in advance.

@Imran2025 primarily it is a tax policy question and this is not the right forum to discuss tax policy positions. From E Invoicing perspective you can issue credit note to reverse old invoice and issue a new invoice. The impact on seller’s output VAT liability and buyer’s input VAT deduction eligibility should be assessed by respective parties’ tax teams.

Also both parties may consider an additional point that as per Article 40(10) of VAT Regulations, buyer will have to reverse input VAT on invoices that remain unpaid for more than 12 months.
