La Reforma Tributaria derivada del proceso armonizador comunitario y su repercusión en el Impuesto sobre Sociedades

Abstract

Three recent modifications of IS are analyzed, in particular, the limitation on the deductibility of financial expenses, the deduction of the negative income from permanent establishments abroad and new developments in the exit tax on permanent establishments, which are example to represent the limits to future tax reform. These limits will operate in the sense that the new regulation can not
be altered by future reforms, as they result from the unstoppable harmonization and coordination of European corporate taxation.
