ZATCA VAT & E-Invoicing Compliance Guide 2026: All 24 Fatoora Waves Explained

Value Added Tax in Saudi Arabia has evolved dramatically since its 2018 introduction, and 2026 marks the most critical year yet. With ZATCA’s Wave 24 of Fatoora e-invoicing now covering every VAT-registered business above SAR 375,000, and landmark amendments published in April 2025 now fully in force, there has never been a more important time to understand your compliance obligations. This guide covers everything: VAT fundamentals, all 24 Fatoora integration waves, the 2025 regulatory changes, and a complete compliance checklist.

1. VAT in Saudi Arabia — The Essentials

Value Added Tax (VAT) is an indirect tax on the supply of goods and services, governed and enforced by the Zakat, Tax and Customs Authority (ZATCA). Introduced on January 1, 2018 at 5% as part of the GCC Unified VAT Agreement and Saudi Arabia’s Vision 2030 strategy, the rate was tripled to 15% on July 1, 2020 to support post-COVID fiscal revenues. This rate remains in force in 2026.

2. VAT Rates & Supply Categories

Not all goods and services are taxed equally under ZATCA’s VAT framework. There are three supply categories, and identifying the correct one for your business activities is critical:

3. VAT Registration — Thresholds & Process

Any business making taxable supplies in Saudi Arabia must assess whether it meets ZATCA’s registration thresholds. Failing to register on time attracts an immediate SAR 10,000 penalty.

• Mandatory Registration (SAR 375,000+): Annual taxable supplies exceed this — registration is legally required. Non-residents providing digital services must also register regardless of threshold.
• Voluntary Registration (SAR 187,500+): Below mandatory but above this — eligible to voluntarily register and reclaim input VAT on business purchases.

Upon registration, ZATCA issues a 15-digit VAT Registration Number (TRN). This must appear on all tax invoices issued. For simplified B2C invoices under SAR 1,000, only the supplier’s TRN is required — the buyer’s TRN is optional.

4. VAT Return Filing — Deadlines & Obligations

All VAT-registered businesses must submit periodic returns through the ZATCA Taxpayer Portal. Frequency depends on turnover:

Even if no taxable activity occurred in a period, a nil return must still be filed. Returns must be submitted by the taxable person or an authorised representative.

5. E-Invoicing (Fatoora) — Complete Guide to All 24 Waves

Saudi Arabia’s e-invoicing mandate — Fatoora (فاتورة) — is one of the most ambitious digital tax transformation initiatives in the world. With Wave 24 announced in September 2025, virtually every VAT-registered business in the Kingdom is now in scope.

Phase 1 — Generation Phase (December 4, 2021)

All VAT-registered businesses must generate, store, and share invoices electronically using ZATCA-compliant software. Invoices must be in XML format (or PDF/A-3 with embedded XML). B2C simplified invoices require a QR code. Electronic copies must be stored for a minimum of 6 years.

Phase 2 — Integration Phase (January 2023 onwards)

Businesses must integrate their billing/ERP systems directly with ZATCA’s Fatoora platform. B2B tax invoices require real-time clearance (pre-approval) before being sent to buyers. B2C invoices must be reported in near-real-time within 24 hours. Each invoice must carry a UUID, cryptographic digital signature, and hash value.

6. Critical ZATCA VAT Amendments — April 2025 (Now in Force)

ZATCA published Board Resolution No. (01-06-24) on April 18, 2025, introducing the most significant overhaul of the VAT Implementing Regulations in years. All three changes are now effective in 2026:

Change 1: New VAT Grouping Rules — Effective October 15, 2025

Businesses under the same economic activity can now form a VAT group and file as a single consolidated taxpayer. Persons in Special Economic Zones (SEZs) are ineligible. Existing VAT groups had a 180-day grace period from April 18, 2025 to restructure.

Change 2: Expanded Deemed Supply Provisions — Effective April 2025

Intercompany transfers between related entities are now classified as deemed supplies and must be subject to VAT at the applicable rate. This closes a compliance gap previously exploited through intra-group arrangements. Businesses should immediately review their intercompany transactions.

Change 3: Digital Marketplace VAT Liability — Effective January 1, 2026

Platforms facilitating sales by non-resident or unregistered suppliers to Saudi consumers are now the VAT-liable party. This affects e-commerce marketplaces, app stores, SaaS resellers, and digital content platforms operating in KSA.

7. Tourist VAT Refund Scheme

As part of Vision 2030’s tourism strategy, ZATCA launched a Tourist VAT Refund Scheme effective April 18, 2025. Eligible international visitors can claim VAT refunds on qualifying purchases made in the Kingdom and physically exported.

• Minimum purchase threshold: SAR 5,000 total (not per item)
• Purchases must be from ZATCA-authorised retailers
• Goods must be for personal use and physically exported from Saudi Arabia
• Excluded: Food and beverages, fuel, vehicles, tobacco

10. Frequently Asked Questions

What is the current VAT rate in Saudi Arabia?

The standard VAT rate in Saudi Arabia is 15% in 2026, unchanged since July 1, 2020. There are no announced plans to change this rate.

How many Fatoora waves has ZATCA announced?

ZATCA has announced 24 waves of Phase 2 e-invoicing integration. Wave 24, announced September 26, 2025, covers businesses with annual VAT-taxable revenues above SAR 375,000, with a compliance deadline of June 30, 2026. This effectively brings the entire VAT-registered population of Saudi Arabia into Fatoora Phase 2 scope.

Which Fatoora wave applies to my business?

Your wave depends on your annual taxable turnover in either 2022, 2023, or 2024. Check the wave table above to identify your threshold. ZATCA notifies affected businesses directly via the portal at least 6 months before the integration date. If you haven’t received notification, contact SynergyStrat for assistance.

What are the April 2025 ZATCA VAT amendments?

Board Resolution No. (01-06-24) introduced three major changes: (1) New VAT grouping rules effective October 15, 2025; (2) Expanded deemed supply provisions for intercompany transfers, effective immediately; (3) Article 47(3) digital marketplace VAT liability effective January 1, 2026.

What happens if my business misses the Fatoora Phase 2 integration deadline?

Missing your deadline exposes your business to fines of SAR 5,000 to SAR 50,000 per violation. Non-compliant QR codes can attract fines of up to SAR 10,000 per invoice. Persistent non-compliance may result in temporary suspension of your VAT registration.
