In the so-called ‘emergency Budget’, the Chancellor set out the first part of the Government’s Roadmap for corporate tax reform to ‘create the most competitive corporate tax system in the G20’ by the end of this parliament.

In producing this Roadmap, possible sources for inspiration for HM Treasury include recent policy deliberations in Australia, the US and the UK – each of which set out different perspectives. But what should the Roadmap deliver for the UK?
