For seven decades, Ireland's foreign direct investment model has been one of the great success stories of small open economy policy. Low corporate tax, a highly educated English-speaking workforce, EU access and a pro-business political consensus combined to attract an extraordinary concentration of the world's most valuable companies to a country of five million people.

That model is not broken. But it is under pressure from multiple directions simultaneously — and an internal IDA Ireland briefing, reported by RTÉ in May 2026, made this case with unusual candour. Ireland must work ever harder to win foreign investment in a fractured global economy where it has little ability to influence major events. The country, the briefing noted, is "not even a middle power."

Understanding what is changing — and what Ireland is doing about it — is essential for any business operating in the FDI ecosystem.

The Tax Advantage Has Narrowed

Ireland's 12.5 per cent corporation tax rate was, for decades, the single most powerful tool in the country's FDI arsenal. That era is over — not because the rate has changed, but because the global context around it has.

The OECD's Pillar Two global minimum tax, now in effect, sets a floor of 15 per cent for large multinational corporations operating across participating jurisdictions. Ireland transposed the necessary legislation and now applies the 15 per cent minimum tax to qualifying multinationals. Corporation tax receipts hit a record €106 billion in 2025, reflecting the profitability of the multinational base — but the competitive advantage that a 12.5 per cent rate once represented against peer economies has been significantly reduced.

The R&D tax credit — long a secondary pillar of Ireland's innovation pitch — was enhanced in Budget 2026, with the rate rising from 30 per cent to 35 per cent and the first-year payment threshold increasing from €75,000 to €87,500. The government has also committed to publishing an R&D Compass to consider further targeted changes to keep Ireland competitive on innovation incentives.

But as RSM Ireland has noted, Ireland's corporate tax framework has become increasingly complex as a result of successive rounds of international tax reform — creating compliance costs and legal uncertainty for multinational groups that were not a feature of the simpler regime of a decade ago.

The Competition Has Intensified

IDA Ireland Chair Feargal O'Rourke, speaking on RTÉ in January 2026, put the competitive challenge directly: countries with very deep pockets — the UAE, Saudi Arabia and others — are now actively pursuing the same FDI that Ireland has historically won. "There's more economic nationalism out there than there had been over the last decade, and we're seeing increased competition," he said.

France and Germany have also placed increased emphasis on FDI attraction. The global trade environment has fractured significantly — the IDA internal briefing cited 2,500 trade restrictions imposed in the first ten months of 2025, five times the equivalent figure from 2015. US tariff policy under the Trump administration has seen the effective US tariff rate rise from 2.3 per cent in January 2025 to 10.3 per cent in January 2026.

Ireland's openness — the very quality that made it attractive to FDI for generations — leaves it more exposed to these global trends than more domestically oriented economies. That is the uncomfortable arithmetic of being a small, deeply globalised country.

Despite this, IDA recorded a remarkable year in 2025 — 323 investments, a 38 per cent increase on 2024, with 78 new-name investors and €2.5 billion in client research, development and innovation expenditure. The EY Attractiveness Survey 2026 noted that software and IT services was Ireland's leading FDI sector, with projects doubling in the year and accounting for more than 40 per cent of the total. Research and development projects accounted for 25 per cent of Irish investments — far ahead of the European average of 7 per cent.

The Infrastructure Gap

The most consistent message from IDA, government and business leaders in 2026 is that tax competitiveness alone is no longer sufficient. The conversation has shifted to infrastructure.

Housing, energy, water and transport infrastructure are now identified by IDA's own strategy and by external analysts as the critical determinants of Ireland's FDI competitiveness over the next decade. The IDA internal briefing specifically flagged speeding up infrastructure delivery and smarter regulatory systems as priorities.

The energy constraint is acute. Data centres — a key component of Ireland's digital economy and AI infrastructure ambition — require significant electricity capacity. Ireland's grid has not kept pace with demand. The government has removed caps on data centre development and committed €3.5 billion in equity to ESB Networks and EirGrid for grid expansion, but the delivery timeline remains a material risk.

As one analysis in the Irish Examiner put it in February 2026: "Our physical infrastructure has not kept pace with our economic ambition. For successive governments, the investment in our roads, rail, water and, perhaps most critically, our power grid has lagged behind the needs of a modern economy."

The Emerging Opportunity

The pressure on Ireland's traditional FDI model is real. But so is the opportunity that the next phase of global investment presents.

IDA's 2025-2029 strategy identifies AI, semiconductors, health and sustainability as the convergent growth drivers of the next investment cycle. Ireland is already positioned in three of the four. The semiconductor sector alone spans 130 companies, generates €13.5 billion in exports and employs 19,000 people. AI infrastructure investment is accelerating — the government covers 50 per cent of investment costs for AI research and innovation projects, and the International AI Summit comes to the RDS in Dublin in October 2026.

More than two thirds of overseas companies already invested in Ireland plan to increase their investment in the next year, according to EY research. The existing base — 1,800 IDA client companies employing over 300,000 people — is not going anywhere. The strategic task is to deepen that base and diversify it into the next generation of high-value sectors before competitors do.

Ireland's English language, common law legal system, EU membership, political stability and decade-deep talent relationships with the world's most valuable companies remain genuine differentiators. In a world of increasing geopolitical uncertainty, those qualities are becoming more valuable, not less.

The Bottom Line

Ireland's FDI model is not failing. But the conditions that made it exceptional for seventy years are changing faster than at any previous point. The tax floor has risen. The competition has deepened. The infrastructure demands have grown. And the sectors driving the next wave of global investment — AI, semiconductors, advanced manufacturing, green technology — require capabilities that go well beyond a favourable tax rate.

Ireland has the track record, the talent and the institutional expertise to compete for the next generation of FDI. Whether it has the infrastructure, the regulatory speed and the policy ambition to do so is the question that 2026 is beginning to answer.
