Spain ranks among the weakest-performing EU countries for tax certainty in a recent comparative study, underscoring how legal unpredictability is emerging as a key – and often overlooked – constraint on Europe’s competitiveness.
The report, published by EPICENTER and authored by economic analyst Diego Sánchez de la Cruz, compares tax systems across 16 EU Member States, focusing not on tax rates but on how consistently and reliably tax rules are applied in practice.
Its findings suggest that while tax debates in Europe tend to focus on rates and revenues, it is legal certainty – or the lack of it – that increasingly shapes business decisions.
