What percentage of all tax raised between 2000 to 2017 has gone into the profit of private companies.

We said

Thank you for your request.

Unfortunately we do not have the information to answer this question. Statistics are available for the total amount of tax received by the public sector and for the total amount of money spent by the public sector. For these statistics please see the public sector finances release which contains detailed data on both tax revenue and public sector expenditure in Annex A.
