Escalating uncertainty and competition in business taxation

Political events over the last year have caused turmoil in many areas of policy, including taxation. What should be the position of the UK and other countries in the light of Brexit and possible fundamental tax reform in the USA? How are countries assimilating the OECD BEPS proposals, the EU Anti-Tax Avoidance Directive and the use by the European Commission of the state aid rules?

President Trump has declared an aim of reducing the US corporation tax rate to 15%. The House of Representatives Ways and Means Committee has proposed a fundamental reform of US corporation tax - to move to the destination-basis long-advocated by the CBT. Either of these reforms would have far-reaching effects on multinational business and on other countries.

Should the UK view Brexit as an opportunity to cast off the constraints on UK taxes of the EU fundamental freedoms? Or should we view Brexit as imposing a harmful shock on the UK economy, which needs to be addressed by an offsetting relaxation in business taxation?

The UK – as other countries – faces a choice between competition for inward investment and the protection of the tax base against profit shifting. For the latter, the UK has pursued cooperation with other countries through the OECD BEPS project, but it has also taken unilateral action – for example with the Diverted Profits Tax. This dilemma of competition versus protection of the tax base has now been heightened by Brexit and the US proposals.  

The CBT’s annual summer conference addressed the most important factors shaping the agenda for business taxation in the UK and elsewhere, with these questions debated by leading speakers from business, government, academia and the professions.
