sign bilateral tax-treaties with the haven, and also to avoid being black-listed. This issue has caused debate on what constitutes a tax haven, with the OECD most focused on transparency (the key issue of traditional tax havens), but others focused on outcomes such as total effective corporate taxes paid. It is common to see the media, and elected representatives, of a modern corporate tax haven ask the question, "Are we a tax haven ?" For example, when it was shown in 2014, prompted by an October 2013 Bloomberg piece, that the effective tax rate of U.S. multinationals in Ireland was 2.2% (using the U.S. Bureau of Economic Analysis method), it led to denials by the Irish Government and the production of studies claiming Ireland's effective tax rate was 12.5%. However, when the EU fined Apple in 2016, Ireland's largest company, €13 billion in Irish back taxes (the largest tax fine in corporate history), the EU stated that Apple's effective tax rate in Ireland was approximately 0.005% for the 2004-2014 period. The EU's position was found, on appeal in the EU's court, to be unsupported by the facts. However, the G7 leaders in the wake of reporting about a Microsoft subsidiary's level of taxation in 2020, have proposed an agreement on a global minimum corporate tax rate of 15%. Activists in the Tax Justice Network propose that Ireland's effective corporate tax rate was not 12.5%, but closer to the BEA calculation. Studies cited by The Irish Times and other outlets suggest that the effective tax rate is close to the headline 12.5 percent rate – but this is a theoretical result based on a theoretical "standard firm with 60 employees" and no exports: in reality, multinational businesses and their corporate structures vary significantly. It is not just Ireland, however. The same BEA calculation showed that the ETRs of U.S. corporates in other jurisdictions was also very low: Luxembourg (2.4%), the Netherlands (3.4%) and the US for multinationals based in other parts of the World. When Gabriel Zucman, published a multi-year investigation into corporate tax havens in June 2018, showing that Ireland is the largest global corporate tax haven (having allegedly shielded $106 billion in profits in 2015), and that Ireland's effective tax rate was 4% (including all non-Irish corporates), the Irish Government countered that they could not be a tax haven as they are OECD-compliant.
