VdA's Tax practice area, present since the first edition, contributes once again to the book "Cadernos IVA 2021", the ninth edition of a project promoted by Católica Tax, under the coordination of Professor Sérgio Vasques.

This book is a collection of papers on VAT by authors specialised in this field from the consulting, legal, academic and business world.

VdA contributed with two articles, one co-authored by Conceição Gamito (Senior Adviser), Rita Simão Luís (Associate) and Nídia Rebelo (Trainee), entitled "The Expiry of the Right to Assess VAT for Undue Deduction", and the other by Vítor Loureiro e Silva (Associate), entitled "Reflections on the Inversion of the VAT Taxable Person".
