DDTAX is focused on providing a highly personalized service to its clients, with the direct involvement of partners in all activities, by fully comprehending clients' problems and delivering a tailor-made strategy for tax litigation and a highly technical and assertive tax consultancy.

As a tax and customs law boutique, the firm is focused on complex and strategic demands. To achieve this, it has developed a culture of combining academic refinement, a pragmatic approach on the problems, closeness to the client’s reality, a profound knowledge on administrative and judicial jurisprudence, and creative thinking on the cases, being able to deliver a clinical look on strategic cases, with deep and efficient insight.

The firm was created just after its partners left the Administrative Council of Tax Appeals (CARF),  the main Admnistrative Tax Court in Brazil, where they stood out for their very technical and in-depth decisions, which have had wide repercussions in the tax environment, and brought great prestige and notoriety for them. The two founding partners, Carlos Daniel Neto and Diego Diniz, have been lawyers for a long time, both are very respected by their peers in academic and professional circles, thanks to their solid academic background and their long experience in CARF, and are often invited as guest speakers at tax courses and specialized seminars. The third partner to join, Antônio Atulim, is a former (retired) Tax Auditor from the Federal Revenue Office, who worked as a Tax Judge at CARF for 13 years and joined the firm to strengthen both litigation and consultancy expertise.
