E-invoicing penalties and the waiver initiative: what ends on 31 December 2026

Each of these is a regulatory compliance failure, not a clerical error. And their treatment varies by the violation's seriousness and recurrence, per ZATCA's published schedules — which is what you must check when needed, because this guide does not print unconfirmed amounts.

• Not issuing electronic invoices inside an approved connected solution — paper invoices or invoices issued from a spreadsheet outside the integration system still count as a violation.
• Issuing simplified household invoices without the mandatory QR code, or failing to report them within 24 hours.
• Tampering with an invoice after clearance or reporting — editing, deleting or reissuing it instead of correcting it with a note.
• Omitting mandatory invoice fields, especially incorrect buyer names or codes on standard invoices.

The Fines and Financial Penalties Waiver Initiative ZATCA ran in recent rounds allowed taxpayers to settle fines from earlier periods and closed material violations in their files. It ends on 31 December 2026, after which late joiners to Phase 2 enter January with no waiver for any remaining unresolved violations, on top of the Wave 25 integration date of 1 February 2027.

The waiver does not postpone the deadline, and it is not a permission to miss the date. It cancels past fines under conditions; it does not exempt future obligations. The practical reading is the opposite: the authority kept a window open to settle the dust before the deadline strikes. Use it.

Firms get fined for defective routine, not for conspiracy. The four operations that prevent nearly all e-invoicing violations are: generating every invoice inside the same connected system, classifying by buyer at the moment the invoice is written, reporting simplified invoices on the day of issue, and correcting mistakes with notes instead of editing. None of them is used concurrently with the deadline.
