The US could benefit to the tune of €57 billion a year.
Based on OECD tax figures for 2016 and 2017, the Observatory estimates that the rule change would have seen Ireland’s corporate tax take increase by €7.7 billion or 91% in 2016 and €12.4 billion or 137% in 2017.
Luxembourg would have seen its corporate tax take increase by 108% in 2016 and 182% in 2017.
The EU average increase would have been 15% in 2016 and 18% in 2017.
The OECD average would be an increase of 7% in 2016 and 12% in 2017.
The Observatory’s report finds the EU-27 would see its combined corporate tax revenue increase by a quarter or €83 billion.
The US could benefit to the tune of €57 billion a year.
Developing countries would benefit less with an increase of €6 billion for China, €4 billion for South Africa and €1.5 billion for Brazil.
The report finds developing and low-income countries will benefit less as most multinationals are headquartered in high-income countries.
If ‘carve-outs’ are applied, which are tax allowances for expenditure on payroll and investment in factory sites and other assets in countries, then the potential revenue in the EU-27 would be reduced to around €64 billion.
Over ten years, as the value of the ‘carve-outs’ decline, the potential extra revenue could be reduced by 14%.
