Following the Government statement on overpayments and underpayments in the PAYE system, Harriett Baldwin raises her concerns that other problems with the HMRC computer system have yet to be uncovered. Harriett Baldwin (West Worcestershire) (Con): A couple of years ago, HMRC lost my personal information and that of 25 million other people on the child benefit disc, and in my constituency surgeries each week, HMRC problems consistently generate the most casework. In opening the boot-or the bonnet-of the car that is the computer system at HMRC, what other problems is the new mechanic going to find? Mr Gauke: HMRC has faced many problems and challenges over recent years: a merger, coping with a complicated tax credits system, and a number of other issues. We need to be realistic about what can be done with our tax system-tax simplification is indeed important-and allow HMRC to focus on its key concerns and do the very important job that it has to do. | Hansard
