Ireland publishes a three-phase VAT modernisation timeline starting November 2028

What changed in detail

Irish Revenue published a VAT Modernisation Timeline, updated 20 July 2026, setting three phases for mandatory e-invoicing and real-time digital reporting:

• Phase 1 — November 2028. VAT-registered large corporates implement mandatory e-invoicing and real-time reporting for domestic B2B transactions. Revenue notes this phase affects relatively few businesses, many with existing international e-invoicing experience.
• Phase 2 — November 2029. The domestic obligation extends to VAT-registered businesses engaged in cross-border EU B2B trade subject to zero-rate arrangements, giving them time to familiarise themselves domestically before the EU-wide system becomes mandatory.
• Phase 3 — July 2030. Full implementation of the EU ViDA requirements for cross-border EU B2B transactions across all Member States; Irish businesses already on the domestic system transition to the EU obligations.

For all phases, Revenue states that businesses must be able to receive and process e-invoices from any supplier mandated to issue them.

What it means

Ireland has put dates on the board ahead of the legislation that will carry them, so treat these as planning anchors rather than as obligations with a legal basis you can cite yet.

The receive-capability requirement is the one that bites earliest and is easiest to underestimate. It is not phased by size: from Phase 1, any business trading with a mandated large corporate needs to accept a structured invoice, which for many finance teams is a bigger change than issuing one. Scoping this as “we are not a large corporate, so 2028 is not our problem” is the mistake the timeline is written to prevent.
