Practice head(s):

María Inés Brandt; Gabriel Gotlib; Walter Keiniger; Fernando Vaquero


María Ines Brandt has extensive tax knowledge and has become a partner for us when making decisions with a tax impact. She is an excellent professional.

The firm has experts in all areas of the business. They always provide thorough analysis.

Walter Keiniger has strong knowledge and is proactive with solutions.

A team with extensive experience and knowledge in tax matters, in a very complex jurisdiction given the continuous changes applied by the authorities.

They think “out of the box” to try to provide solutions to the questions that arise with the continuous increase in legal restrictions.

The team is made up of members with a lot of experience and solid knowledge in taxation. They balance analysis between the legal theoretical framework and concrete experience gained in administrative and judicial courts.

For a client the most important attribute of a tax practice is having confidence in the advice you are given. Tax advice is often hedged, which makes it a gamble for the client. The tax practice at Marval, and particularly the advice of Walter Keiniger, does not follow this pattern. The advice is clear and well-researched and therefore valuable.
