This survey summarises the state and development of European tax policy, in particular discussing the harmonisation progress
in direct as well as indirect taxes. Based on an overview over the theoretical and empirical literature on tax competition,
we further ask whether increased tax coordination is necessary to prevent a race to the bottom. We show that theoretical predictions
on the outcome of tax competition are ambiguous, and the empirical evidence in this regard is inconclusive as well. This,
in turn, gives rise to an only limited scope of stronger tax harmonisation.
