Phase 2 — Wave 23
OverdueOverdue by 81 days
Your integration deadline (31 March 2026) has passed. Businesses in Wave 23 should already be live on the Fatoora platform — integrate immediately to limit non-compliance penalties.
Saudi e-invoicing runs in two phases. Phase 1 (Generation) has applied to all resident VAT-registered taxpayers since 4 December 2021. Phase 2 (Integration) began on 1 January 2023 and is being rolled out in waves, each defined by a VAT-taxable-revenue band, starting with the largest businesses.
Wave 24 effectively brings the entire VAT-registered population into scope, because SAR 375,000 is also the mandatory VAT registration threshold. Once integrated, standard (B2B/B2G) invoices must be cleared by ZATCA in real time and simplified (B2C) invoices reported within 24 hours — see the Generation vs Integration explainer.
Each taxpayer's deadline depends on their wave, which is set by annual VAT-taxable revenue. The most recent waves: Wave 23 (turnover SAR 750,000–1,000,000) had to integrate by 31 March 2026, and Wave 24 (turnover above SAR 375,000 up to SAR 750,000) must integrate by 30 June 2026.
ZATCA assigns your wave by your highest annual VAT-taxable revenue in the relevant reference years (2021–2024 depending on the wave). Larger businesses integrated first; Wave 24 brings the rest of the VAT-registered population — anyone above the SAR 375,000 registration threshold — into Phase 2.
Phase 1 (Generation), live since 4 December 2021, requires you to generate and store structured electronic invoices. Phase 2 (Integration) additionally requires your system to connect to the Fatoora platform, add a UUID, cryptographic stamp and digital signature, clear standard (B2B/B2G) invoices in real time, and report simplified (B2C) invoices within 24 hours.
