Edward Troup has been announced as executive chair of HMRC, while Jon Thompson will become chief executive, the government has confirmed today.
Troup, who is currently HMRC’s tax assurance Commissioner, will take up his new role on 5 April.
Thompson, currently permanent secretary at the Ministry of Defence, will join HMRC "shortly".
Heywood said: "Edward’s deep tax expertise and long experience in both HMRC and HM Treasury make him an excellent choice to lead the department through an important phase of change and amid unprecedented public interest in taxation.
"Jon’s experience of leading one of the biggest departments in government, coupled with his strong financial background, make him strongly placed to deliver HMRC’s ambitious transformation plans, large-scale operations and modern customer services."
Under the new leadership structure, Troup will chair HMRC’s board and Thompson will chair HMRC’s executive committee. He will also be the accounting officer for HMRC.
The arrangements for assuring large tax settlements in HMRC will be reviewed after they start.
