Abstract

Key messages: The success of the recently agreed international tax reform hinges on a technical issue in the design of the Pillar 2 global minimum tax Pillar 2 ensures the minimum taxation of ‘residual’ (e.g. non-routine) profts at 15%. ‘Routine’ proft is not subject to Pillar 2. The effects depend on which of two possible options is used: Option 1 removes the incentive to compete below a liability of 15% of residual profts and puts a floor to tax competition Option 2 still maintains an incentive for governments to compete by reducing their taxes – possibly all the way to zero. Consequences for tax competition depend on the technical details to be revealed. Announcement containing more details of the proposal are expected shortly.
