The year 2025 marks a critical phase for e invoicing in KSA, as the second phase ”Integration Phase” moves forward. Staying compliant with ZATCA’s timelines is now more important than ever.
In this article, we highlight the key deadlines for e invoicing in KSA in 2025, including details on each wave and how EZ Integrated can help you meet compliance efficiently.
Why These Dates Matter for e Invoicing in KSA
ZATCA has mandated e invoicing in KSA for all VAT-registered businesses. Phase 2 requires companies to integrate their invoicing systems with the government’s FATOORA platform.
To simplify compliance, ZATCA introduced a wave-based rollout. Each wave has a specific timeframe for integration and testing.
Missing these deadlines can result in financial penalties. Therefore, businesses must act early to avoid risks and ensure timely integration.

Take Advantage of the Penalty Waiver Initiative
ZATCA extended its penalty waiver initiative until June 30, 2025. This allows businesses to correct past violations without fines—if they meet specific conditions.
Covered violations include late VAT registration, delayed returns, late payments, and issues with e invoicing in KSA.
To benefit, businesses must:
- File all due VAT returns
- Pay outstanding taxes or request installment approval
- Comply with approved payment schedules
Note: The waiver does not cover cases of tax evasion or penalties paid before the program’s start date.
