Sergio André’s new book, “Tax Planning in Marco Aurélio Greco’s Theory” (“O Planejamento Tributário na Obra de Marco Aurélio Greco”), has just been released. The book’s focus is to present a descriptive and yet critical analysis of the theory that is the most relevant in Brazil pertaining to the limits of legitimate tax avoidance. During the second semester of 2018, Sergio André and Marco Aurélio met a few times and had long conversations about Greco’s academic career and his theory. These conversations were included in the book. To view the book in full (in Portuguese), click here.
