The ETRs of 0–2.5% from O'Rourke's BEPS tools have drawn international criticism. Academic research has shown Ireland as a major
tax haven, and in June 2018 tax academics showed Ireland to be the largest global
tax haven, helping U.S. multinationals to shield over $100 billion in annual profits from Irish and U.S. taxation. O'Rourke's defense of Ireland's low corporate ETRs for U.S.–controlled multinationals is part of Ireland's "
green jersey agenda" to advance "
Ireland Inc." over other potential consequences, such as reputation or
financial risk, which is not an uncommon political strategy in Ireland. Regardless of the tax losses to other nations, O'Rourke's BEPS tools have brought prosperity to Ireland. 25 of Ireland's top 50 firms (by turnover) are
U.S.–controlled multinationals, employing one quarter of Ireland's private sector workforce, paying 80% of Irish business taxes, and creating 57% of Irish private sector non-farm value-add in Ireland. and on Irish corporate taxation policy. O'Rourke has sat on several major Irish State taxation review groups, including the major 2009
Commission on Taxation, and is one of the 5 people named in Ireland's
"Independent Persons of Standing" list under the Double Taxation Arbitration Convention. In February 2014, he was named in
The Irish Times 50 people who run Ireland list. O'Rourke sits on the Board of the American Chamber of Commerce Ireland, the lobby group for U.S. multinationals in Ireland. In March 2018, he noted the U.S.
Tax Cuts and Jobs Act of 2017 will be a challenge to Ireland's U.S. economic model but that Ireland should be able to withstand it. In April 2018, he advised that the Irish State should build a
rainy day fund. O'Rourke maintains an active Twitter account. ==See also==
