In the deepest and most far reaching analysis of the UK tax system in more than 30 years, the Mirrlees Review puts the case for radical tax reform. It shows how the current system is inefficient, overly complex and frequently unfair. And it sets out a range of proposals designed to increase output and welfare.

Government, through the tax system, takes around £4 in every £10 earned in the economy. It is not surprising that getting tax design wrong can be hugely costly.
