The Office of Tax Simplification (OTS) celebrates its tenth anniversary later this year. The initial task of building the Office was taken on by its first Tax Director, John Whiting, supported by Michael Jack as chair. In 2015, the OTS was made an independent office of the Treasury and in 2016 was given statutory authority. The statute provides that the OTS shall have a majority of independent board members (four), as well as the chair and the tax director. The board is completed by senior officials from HM Treasury and HMRC.
