About

Provided by Mannrich e Vasconcelos Advogados

Our tax litigation practice represents clients with a creative and strategic approach, considering case law, cost-benefit, and extralegal factors such as economic impact data.

In the administrative sphere, our practice is led by Carlos Henrique de Oliveira, former president of the Administrative Council of Tax Appeals (CARF), whose experience encompasses complex topics, including social security disputes, income tax issues, and other intricate matters.

We also maintain a dedicated team in Brasília for representation before the Superior Courts, which includes Nina Pencak, a former clerk at the Supreme Court (STF). In São Paulo, our office is strategically located near the Federal Courts and the Courts of Appeals, enabling our team to engage proactively.

We are dedicated to the development of innovative arguments for our clients. We highlight the exclusion of sales tax from the PIS/Cofins calculation base, a discussion that for a long time was considered inapplicable to ethanol and gasoline companies, but based on public data obtained by our team, we were able to obtain favorable decisions.

Our team also provides advisory services on important public policy projects and tax debt transactions. We have been dedicated to the development of technologies to identify judgment trends and the best arguments to be used in lawsuits. Large companies seek our assistance in these projects, which aim to create a strategic view of tax litigation, mitigating conflicts and reducing costs.
