Daniel & Diniz Advocacia Tributária

Daniel & Diniz (DDTAX) was created by former administrative tax judges at CARF, who joined forces to develop a tax law and customs practice aimed at designing technical, creative, and effective solutions for today’s challenges in those fields. Their approach combines legal sophistication, hands-on experience, and close collaboration with clients.

The firm has a solid track record of good results in administrative tax litigation, with significant current results in IRPJ, CSLL, PIS and COFINS cases, as well as highly complex customs cases.

The firm's main objective is always to exceed our clients’ expectations in achieving the best possible outcome for their challenges, solidifying our position as a national leader in tax and customs law.

Our firm stands out for its ability to identify and develop solutions that often go unnoticed, always employing a strategic, technical, and cooperative outlook. We pursue each matter in an innovative manner—thinking outside the box and exploring possibilities that others may not, free from common assumptions.

This distinctive perspective allows us to discover efficient avenues and effective opportunities, consistently aiming to deliver a level of excellence that exceeds expectations and drives our clients’ success.

We highly value intellectual development, scientific analysis, and debate, coupled with a solid understanding of our clients’ activities. These pillars guide our approach to crafting responses that combine deep technical knowledge with practical accuracy.

At DDTAX, professional development is driven by collective effort and the perspectives of our entire team, always under the direct and close supervision of the partners. Our goal is to deliver the most technically robust solutions, encouraging open discussion and the creative formulation of new ideas.

Our relationships with clients are built on a highly personalized approach, always focused on fostering mutual trust. We remain constantly available to provide support and clarify questions, ensuring clients feel secure throughout their activities and in their case management. We achieve this through transparency and clarity in our communication.

Our commitment extends beyond mere service delivery: we work with absolute dedication to achieve success, adopting a strategic posture enhanced by innovative ideas to secure the best possible results for every case.
