On 5 October 2026, coinciding with the Irish Budget 2027 announcement, EY Ireland released a detailed assessment of how the Budget’s tax measures can strengthen Ireland’s international investment appeal. The analysis focuses on four pillars: infrastructure investment, energy security, talent availability, and tax certainty. With the implementation of OECD Pillar Two (global minimum 15% tax) effective from January 2024 for large MNEs, Ireland’s traditional 12.5% corporate tax rate advantage has been neutralized for in-scope groups. Consequently, the report argues that future competitiveness hinges on non-tax factors underpinned by a stable, transparent, and predictable tax administration. The Budget 2027 commitments include a multi-year infrastructure capital envelope, accelerated grid connection for renewable energy, and expansion of the National Training Fund – all supported by tax policy measures such as extended capital allowances for energy-efficient equipment and enhanced R&D credit certainty provisions.
Key Takeaways
- Tax Certainty Protocol: The government has committed to a new “Tax Certainty Protocol” requiring advance publication of tax guidance on major policy changes, a 12-month lead-in for legislative changes affecting cross-border structures, and a dedicated MNE liaison unit within the Revenue Commissioners. This directly addresses investor concerns about retrospective changes and unpredictable audit practices.
- Infrastructure-Linked Tax Incentives: New accelerated capital allowances (ACA) for investments in designated “strategic infrastructure corridors” (e.g., water, broadband, transport) aim to crowd-in private capital. Companies investing in qualifying assets in these zones can claim 125% of expenditure in Year 1, subject to EU State Aid approval.
- Green Transition Tax Package: A suite of measures including a refundable tax credit for green hydrogen production, enhanced Section 110 treatment for renewable energy project finance, and a carbon leakage protection mechanism for energy-intensive industries (EIIs) aligned with EU CBAM regulations.
Impacts
- Foreign Direct Investment (FDI) Decisions: The certainty protocol reduces the risk premium for Ireland in location benchmarking models, potentially improving Ireland’s ranking in indices like the IMD World Competitiveness Yearbook and EY’s own Attractiveness Survey.
- Domestic Enterprise: The ACA for strategic infrastructure benefits Irish construction, engineering, and services firms in the supply chain, while the green hydrogen credit supports the emerging indigenous renewable energy sector.
- Compliance & Reporting: MNEs must update their tax risk frameworks to incorporate the new liaison unit procedures and ensure transfer pricing documentation reflects the enhanced certainty environment. The changes also interact with Country-by-Country Reporting (CbCR) and Pillar Two GloBE data requirements.
