Effective corporate tax rate ‘under 11%’

The effective corporate tax rate paid by companies in Ireland is just under 11%, according to an in-depth analysis prepared for the Department of Finance.

The department commissioned UCC economics lecturer, Seamus Coffey, to look at the eight measures available used to calculate the effective tax rate. These estimates range from 2.2% to 15.5%.

Mr Coffey found the two most accurate measures for calculating the effective corporate tax rate over the past 10 years was the CSO and Revenue. Based on CSO figures, firms had an average effective corporate tax rate of 10.9% over the past 10 years and a rate of 8.4% for 2012.
