Introduction
1.These explanatory notes relate to the Corporation Tax Act 2010 which received Royal Assent on 3 March 2010. They have been prepared by the Tax Law Rewrite project at HMRC to assist readers in understanding the Act. They do not form part of the Act and have not been endorsed by Parliament.
2.The notes need to be read in conjunction with the Act. They are not, and are not meant to be, a comprehensive description of its contents. So if a section or part of a section does not seem to require explanation or comment, none is given.
3.The commentary on each section indicates the main origin or origins of the section. A full statement of the origins of each section is contained in the Act’s Table of Origins.
4.At the end of the commentary, there is supporting material in two annexes:
	Annex 1 contains details of the minor changes in the law made by the Act;
	Annex 2 contains lists of:the Extra-Statutory Concessions to which the Act gives effect,the minor changes made by the Act which involve giving statutory effect to principles derived from case law, andprovisions not included in the Act on the grounds of redundancy.
