A central proposal was the establishment of a Welsh Revenue Authority as a Non-Ministerial Department, which would therefore be operationally separate from Welsh Ministers and accountable to the Assembly.  That received strong backing, as did the establishment of a Taxpayers’ Charter, which would set out clearly the standards of behaviour and values of the Welsh Revenue Authority and also of Welsh taxpayers.
