Structure and current context of tax-legal relationships

Abstract

This article offers a drone’s-eye perspective on the architecture of tax legal relationships, deconstructing their structure beyond the traditional view of mere tax obligation. The research identifies a dense substantive core, composed of primary rights and duties, while extending its analysis to a vast formal periphery where multiple layers of ancillary rights and duties intersect, defining the daily interaction between the State and taxpayers.

By mapping these layers, the text provides a clearer understanding of how the individual's legal standing is shaped by a web of norms that requires increasingly sophisticated tax risk management.

The text focuses critically on the paradigm shift currently underway in Tax Law, driven by unprecedented technological advancements and a technical sophistication that tests the boundaries of legal certainty. It discusses the role of the parliamentary statutory reserve (reserva de lei) not only as a jurisdictional rule but as a guarantee of clarity and transparency that must protect citizens' trust in the face of taxing power. Furthermore, it warns of the dangers of hypertrophied and hermetic legislation, arguing that tax justice is inseparable from the intelligibility of norms and respect for the democratic forum.

By bridging classic legal dogmatics with the challenges of modernity, this contribution is aimed at those seeking to decipher the current dynamics of the tax system and its evolution within a context of increasing institutional complexity.
