ZATCA Wave 24: Emergency 4-Day Compliance Guide for Saudi SMEs 2026

4 Days Left Before ZATCA Wave 24 Enforcement: What Saudi SMEs Must Do Right Now

As of today, Friday June 26, 2026, Saudi businesses have exactly four days before the ZATCA Wave 24 deadline expires. On June 30, 2026, the compliance window closes permanently. From July 1, the Zakat, Tax and Customs Authority enters full enforcement mode — no grace periods, no waivers, and fines starting at SAR 5,000 per violation, escalating to SAR 50,000 per invoice.

If your business has not completed Phase 2 integration with the Fatoora portal yet, this is your emergency guide. Wave 24 brings the revenue threshold down to SAR 375,000 for the first time, pulling tens of thousands of small and medium businesses into mandatory e-invoicing scope that were previously exempt. If you are one of them, the next 96 hours are critical.

What ZATCA Wave 24 Actually Requires

Wave 24 is part of Phase 2 (Integration Phase) of Saudi Arabia's national e-invoicing program. Unlike Phase 1, which simply required businesses to issue structured digital invoices, Phase 2 mandates a live, automated connection between your invoicing system and ZATCA's Fatoora portal. The technical requirements include:

• Issuing invoices in ZATCA-compliant XML format (UBL 2.1 standard)
• Submitting B2B invoices to Fatoora for clearance before delivering them to buyers
• Reporting B2C simplified invoices to Fatoora within 24 hours of issuance
• Including cryptographic stamps and QR codes on all invoices
• Using only ZATCA-certified e-invoicing solutions

These are not optional add-ons — they are hard technical requirements that cannot be satisfied by manual workarounds. Fatoora processed over 8.2 billion e-invoices in 2025 alone, a 64% surge from the previous year. The infrastructure is live and the enforcement deadline is real.

Who Is Affected by the SAR 375,000 Threshold?

Wave 24 targets every VAT-registered business in Saudi Arabia whose taxable revenue exceeded SAR 375,000 in 2022, 2023, or 2024. This is a significant expansion compared to Wave 23, which had a SAR 750,000 threshold, bringing thousands of smaller businesses into mandatory Phase 2 compliance for the first time in the program's history.

Industries explicitly in scope include:

• Retail stores, e-commerce platforms, and distributors
• Professional service firms: accountants, consultants, engineers, and legal advisors
• Restaurants, cafes, hotels, and hospitality operators
• Private clinics, medical centers, and diagnostic laboratories
• Construction subcontractors and logistics and delivery companies

The practical test: if your business is VAT-registered and generated more than SAR 375,000 in taxable revenue in any of those three years, you must comply before June 30 — even if you have not yet received a formal notification letter from ZATCA. The obligation exists regardless of whether notification was received.

What Happens After July 1, 2026?

The consequences of missing the deadline are immediate and compound with every invoice issued after July 1:

• Invoice rejection: B2B invoices not cleared by Fatoora will be rejected by the portal, completely blocking your sales to other businesses with no manual workaround available
• Lost VAT input deduction: Your business customers cannot claim the 15% input VAT deduction on purchases from you if your invoices are not ZATCA-compliant, making you less competitive than compliant suppliers offering the same products or services
• Fines of SAR 5,000–50,000 per violation, applied per non-compliant invoice and accumulating with every sale made after July 1
• Permanent loss of penalty amnesty: ZATCA's initiative for correcting historical e-invoicing errors and waiving related penalties expires on June 30 — after that date, retroactive fines cannot be reversed under any current ZATCA program

The compounding risk is the real danger. A business issuing 100 invoices per month faces potential fines exceeding SAR 500,000 in the first month of non-compliance alone, before ZATCA even begins formal enforcement action targeting the business directly.

How Watily Solves This

With four days remaining, you still have time — but not much of it, and ZATCA-certified solution providers are operating under peak demand pressure this week. Watily's ZATCA e-invoicing solution is built specifically for Saudi SMEs, providing complete Phase 2 integration with the Fatoora portal without requiring in-house technical expertise, complex IT projects, or large implementation budgets.

What Watily's ZATCA e-invoicing platform delivers:

• Full Fatoora portal integration meeting all Wave 24 technical requirements out of the box
• Auto-generated UBL 2.1 XML invoices with cryptographic stamps and QR codes on every invoice
• Unified Arabic dashboard for managing B2B clearance submissions and B2C reporting in one place
• Arabic-language technical support throughout the onboarding and go-live process
• Compatibility with most existing accounting systems — no need to replace your current setup in most cases

Thousands of Saudi SMEs have already completed their ZATCA compliance through Watily. The system is designed for business owners, not developers — onboarding takes hours, not weeks. That matters enormously when you have 96 hours left to meet a mandatory government deadline.

Your 4-Day Emergency Compliance Action Plan

Here is the exact step-by-step plan for the next four days:

• Day 1 (Today, June 26): Verify your eligibility by checking whether your 2022, 2023, or 2024 taxable revenue exceeded SAR 375,000. If it did, register on Watily's ZATCA platform immediately and begin account setup.
• Day 2 (June 27): Complete your business profile, enter your VAT registration details, and establish the live connection to the Fatoora portal.
• Day 3 (June 28–29): Issue a test invoice and verify successful submission and clearance through the Fatoora system. Resolve any configuration issues before the final day.
• Day 4 (June 30): Issue your first fully compliant production invoice before midnight and confirm it is cleared by Fatoora.

Do not wait until the morning of June 30 — certified providers are under peak demand pressure this week, and starting today gives you the best chance of completing integration before the deadline passes.

Saudi Arabia is not extending the Wave 24 deadline. With SAR 50,000 maximum fines per violation stacking on every invoice from July 1, the cost of waiting vastly exceeds the cost of acting now. Start with Watily today and secure your business before enforcement begins. One decision made in the next 24 hours protects your entire business operation for the months and years ahead.
