HMRC chief executive Lin Homer is to depart the tax service in April after four years as chief executive.
Homer, who was made a Dame in the New Years Honour’s List in recognition of her public sector work, joined HMRC in January 2012.
Her departure comes after a tumultuous 12 months for HMRC, which began 2015 facing criticism over its failure to pursue claims of tax evasion in relation to HSBC’s Swiss private bank, and ended it being told by MPs that its inability to handle calls from the public remained “completely unacceptable”.
HMRC is currently seeking to close all 170 of its offices and relocate to 13 regional hubs, moving more services online in the process.
In a statement announcing her departure, Homer says the beginning of a new spending review period “seemed a sensible time to move on”.
She says: “HMRC has secured ministerial support and funding for our ambitious transformation programme and it has the leadership team in place to deliver it. My successor will be able to put their full weight behind seeing the transformation through to 2020.”
Chancellor George Osborne says: “Lin Homer has made a real contribution to public service modernisation and transformation. She has put the foundations in place that will see HMRC become one of the most digitally-advanced tax authorities in the world.
“It is to Lin’s great credit that the National Audit Office last year judged HMRC to be one of the strongest Departments in Government – a legacy of which she can be rightly proud.”
