US Firms Paid 2.2% Effect Tax Rate in Ireland
By Carl O'Brien
US multinationals reported paying tax rates of 2.2 per cent in Ireland during 2011, according to a new study.
A research paper by Prof James Stewart, associate professor in finance at Trinity College Dublin, also challenges Government claims that effective corporation tax rates in Ireland are just below the headline rate of 12.5 per cent.
Instead, the study suggests Ireland’s effective tax rate for American firms is similar to jurisdictions regarded as tax havens such as Bermuda, based on latest US Bureau of Economic Analysis statistics.
The research paper’s findings come at a sensitive time as Ireland finds itself in the global spotlight for helping multinationals avoid taxes around the world.
