ZATCA E-Invoicing in Saudi Arabia 2026: Complete Guide to Avoid Fines

The Zakat, Tax and Customs Authority (ZATCA) e-invoicing mandate has fundamentally changed how businesses in Saudi Arabia issue invoices. With Phase 2 (Integration Phase) now actively enforced, every business above the revenue threshold must generate and transmit e-invoices in real time. This guide tells you exactly what you need to know.

What Is ZATCA E-Invoicing?

ZATCA e-invoicing (Fatoorah) requires businesses to generate invoices in a structured electronic format (XML) instead of paper or unstructured PDF. Each invoice must contain specific required fields including seller and buyer information, tax registration number (TRN), VAT amount, and a QR code.

The Two Phases Explained

Phase 1: Generation Phase (December 2021)

Businesses were required to generate and store e-invoices electronically. Paper invoices were no longer acceptable. This phase affected all VAT-registered businesses regardless of revenue.

Phase 2: Integration Phase (from January 2023, rolling waves)

Businesses must now integrate their invoicing systems directly with the ZATCA portal. Standard invoices (B2B) require clearance from ZATCA before being sent to the buyer. Simplified invoices (B2C, like retail receipts) require reporting to ZATCA within 24 hours.

Who Is Affected?

Phase 2 is being rolled out in waves based on annual revenue. Businesses with annual revenues above SAR 3 million entered the mandate in the first waves. By 2026, all VAT-registered businesses are expected to be fully integrated.

Key Requirements for Every E-Invoice

• Seller name and VAT registration number
• Buyer name and VAT registration number (for B2B)
• Invoice date and unique serial number
• Description, quantity, and unit price of each item
• VAT rate and VAT amount
• Total amount including and excluding VAT
• QR code (mandatory for simplified invoices)
• Cryptographic stamp (UUID)

Penalties for Non-Compliance

ZATCA applies significant penalties for e-invoicing violations:

• Failure to issue an e-invoice: up to SAR 10,000 per violation
• Failure to keep e-invoice records: up to SAR 50,000
• Manipulating invoice data: up to triple the tax amount
