Corporate tax law in Brazil is complex, constantly changing and often contradictory. Smart companies have an adviser who knows the rules, anticipates the risks and develops a proactive tax strategy.

It is inevitable that every large company in Brazil will someday be involved in some type of tax controversy, whether because of tax notices caused by divergent interpretations of the law, or because they are challenging the validity of some law in court.

Contentious advice may be necessary. Or you may simply need sound planning to help you avoid costly disputes.

The tax lawyers and professionals of Trench Rossi e Watanabe have deep knowledge, experience and understanding of Brazil’s tax laws. They can help you apply them to reduce your company’s risks, help ensure your compliance and maximize your position to the fullest extent possible. Our team studies your business to develop a customized tax solution. Our goal is to ensure that you pay only the taxes due – and nothing more.

Our team has expertise in tax planning and in administrative and judicial controversies. This combination gives you fast and efficient service, making the most of your time and legal budget.
