Last updated: 2026-05-07
Short Definition
Official invoice for VAT-applicable transactions, must include tax registration number, QR code, and tax amount.
Overview
Legal Basis
The electronic tax invoice is based on the Value Added Tax Law issued by Royal Decree No. (M/113) of 1438 AH, and the ZATCA Governor's decision on mandatory electronic invoicing issued in 2021. Phase One (issuance) was in 2021, and Phase Two (linking and integration with ZATCA) began gradually from 2023 according to entity size. The regulation requires all tax-registered entities to issue electronic invoices in specified formats (XML or PDF/A-3 with embedded XML), with strict penalties for violations.
Practical Example
Al-Dhahabi Real Estate office leases a commercial office in Riyadh to Advanced Technology company at monthly rent SAR 15,000 + 15% VAT. Each month, Al-Dhahabi office issues an electronic tax invoice via the Fatoorah system including: Al-Dhahabi name and tax number, Advanced Technology name and tax number, invoice date and number (e.g., INV-2026-03-127), description «Office No. 305 rent for March 2026», base rent 15,000, 15% VAT = 2,250, total 17,250, QR code and digital signature. The invoice is sent to the client, and automatically uploaded to ZATCA. Technology company receives the invoice and registers it in its accounting to deduct Input VAT in its declaration. Both parties are fully and instantly documented tax-wise.
Common Mistakes
- ✗Issuing paper or manual invoices for tax-registered entity — a serious ZATCA violation since 2022 with penalties reaching SAR 50,000.
- ✗Overlooking one of the mandatory elements in the invoice — like buyer entity tax number, invalidates invoice.
- ✗Issuing invoice without QR code — clear technical violation; invoice without QR is invalid for ZATCA.
- ✗Mixing residential property invoices (exempt) with commercial (15%) — causes calculation and tax errors.
- ✗Delaying invoice issuance from actual service date — exposes entity to audit and may be considered evasion.
International Differences
Electronic invoicing systems are spreading globally. In the UAE, ZATCA UAE launches E-Invoicing system gradually from 2024. In Turkey, e-Fatura is mandatory for large entities since 2014, with gradual expansion. In Egypt, the Egyptian Electronic Invoice system is similar, with gradual mandatory application. In the UK, Making Tax Digital (MTD) from HMRC requires keeping digital records. In the European Union, PEPPOL and VAT in Digital Age unify invoicing between member states. In the US, no federal mandate, but some states apply requirements. The Saudi advantage in electronic Fatoorah is speed of application (5 years to cover all sectors), integration with all government platforms (Ejar, Etimad, Najiz), unified QR code for instant verification, and high digital security with approved electronic signature.
