These are taxpayers with an annual income between SAR 375,000 million and SAR 750,000 in either 2022 or 2023.

The confirmed waves so far include:
25th wave Feb 2027 – taxpayers annual income between SAR 0.35 million and SAR 187,500
24th wave Jun 2026 – taxpayers annual income between SAR 750,000 and SAR 350,000
23rd wave Mar 2026 – taxpayers annual income between SAR 0.75 million and SAR 1 million
22nd wave Jan 2026 – taxpayers annual income between SAR 1 million and SAR 1.25 million

- B2C invoices will instead be reported in near-live format, within 24 hours of booking. Paper invoices for customers is still permitted, although e-invoices can be offered. In either case, a QR Code is required.
The latest guidance for businesses above the threshold covers:
- Control requirements, business rules for validation of the xml invoices
- Technical specifications of e-invoices, certain data fields between mandatory, conditional or optional
