“Why Ireland is Changing its Corporate Tax System: A Look at OECD Agreement and Its Impact”

As one of the world’s leading economies, Ireland has established itself as a hub for multinational corporations seeking a favorable tax environment. However, the country’s tax system has recently come under scrutiny with the introduction of new corporation tax rules. The changes are expected to have a significant impact on Ireland’s economy, raising questions about whether the new rules will make the country richer or poorer. In this article, we examine the potential effects of the new corporation tax rules and discuss the implications for Ireland’s future economic growth.


The reason for Ireland’s change in its corporation tax system is due to its participation in an agreement with the OECD to reform the way major companies are taxed. This was an effort to stop large multinational companies from using profits to pay low tax rates, a problem that was previously addressed by the OECD in 2015. Subsequently, an agreement was reached in the European Union to implement a minimum 15% effective tax rate on companies with annual turnover exceeding €750 million. Initially, it was thought that Ireland would have to abandon its existing 12.5% corporation tax rate. However, it was agreed that smaller companies would still pay lower rates. As a result, big companies in Ireland will now pay tax at the 12.5% rate and then a top-up charge to bring their effective rate to 15%. The exact amount this change will raise for the exchequer is difficult to estimate, but last year’s tax figures suggest the increase could be €3.5-€4.5 billion. However, the reallocation of where big companies pay corporation tax may cause some loss for Ireland. Negotiations on the implementation of the reallocation part of the OECD deal are ongoing. Although the 15% part of the deal is now tied down in the EU, the Biden administration in the US might face difficulties in aligning with the OECD deal, potentially causing tensions over the top-up tax’s interaction with the US system for taxing the overseas earnings of its companies.


In conclusion, the new corporation tax rules will undoubtedly have a significant impact on Ireland’s economic landscape. While it’s too early to predict whether they will make the country richer or poorer, it’s clear that the changes will encourage greater transparency and accountability among businesses operating in Ireland. If implemented correctly, these new rules could help Ireland maintain its reputation as a leading destination for foreign investment while also ensuring that corporations pay their fair share of taxes. However, there are also risks associated with these changes, particularly if companies choose to relocate to other jurisdictions with more favourable tax policies. Ultimately, only time will tell what effect these new regulations will have on Ireland’s fiscal health, but for now, it’s important for businesses and policymakers alike to stay informed and adapt to the evolving tax landscape.
