Phase 2 starts in February 2027.
It expands e-invoicing beyond the initial 100 companies to all large VAT-registered companies covered by the second phase.
This means a large VAT-registered business that was not selected for the August 2026 rollout should not assume that it is outside the e-invoicing programme. It should prepare for the February 2027 expansion and check its rollout status with the Tax Authority.
Key points
- Phase 2 begins: February 2027.
- It expands coverage to all large VAT-registered companies.
- Businesses should not wait for their implementation month to begin technical preparation.
- OTA provides rollout support and communicates with rollout participants in advance.
