O aspecto espacial da hipótese de incidência

Abstract

Supported by the bibliography presented at the end of this paper, this study aims to analyze the spatial aspect contained in the tax juridical rule. Within this context, it is mandatory to examine the Constitution, in particular the distribution of tax competences, insofar as we intend to demonstrate that, by describing the materiality that may be possibly reached by the laws that create taxes, the Federal Constitution prevents conflicts between the units that form the Brazilian federation, therefore this matter is not at the mercy of rules of lower hierarchy, as there will be no room for fictions that may distort the constitutional delimitations. A different situation is that of international multiple taxation, and because it occurs in other plane, that of sovereignty of the States, it cannot be mediated by the Constitution of one of them. These requisites ─ presented in the first part of this paper, with no prior criticism of dissenting views (although put to test) ─ will suit the purpose of the final part of this study, i.e., the analysis of the rules that introduce the taxes within the authority of the Federal Government, the States and the Cities. At the end, it will be possible to find that the worries that gave rise to this study are dispelled to the extent that we conclude that the Federal Constitution limited the field of action of the taxing authorities and does not allow them to push the limits of their ruling spaces
