Homer led HMRC between 2012 and April this year, and was made a Dame in the 2016 New Year’s Honours List.

The Advisory Committee on Business Appointments (Acoba) confirmed it had approved Homer’s application to become a member of the University of Birmingham Council, an unpaid role which the watchdog said was in line with her ‘longstanding’ relationship with the university. She was awarded an honorary doctorate by Birmingham in 2013.

Her stint leading the tax authority was controversial and attracted heavy criticism, particularly over its effectiveness in its attempts to curb tax avoidance.

She was called before the Public Accounts Committee on a regular basis, not only to defend HMRC but also to explain some of the more questionable tax arrangements made with companies, global profit shifting and the Swiss private accounts leaks.  

Homer has also presided over HMRC’s switch to digital working, which saw a major shake-up of tax offices at the end of last year, in a move to consolidate services into 13 regional centres. 

Upon her departure from HMRC, Homer received a £2.4m pension pot following years working in the Civil Service.
