The Firm

We are tax lawyers with background in accounting and vastly experienced in complex tax matters, with solid academic background and proven professional experience, both in Brazil and in the United States, with a global approach on taxation.

The idea for setting-up our own tax boutique was born with a handshake in 2007, when we (Matheus and Leonardo) were colleagues in the Post-Graduation course in International Tax, hence, in an academic environment. Twelve years later, we combine our professional expertise with that of competent colleagues in a life project of technical excellence, strategic efficiency and pragmatic service offering. We love what we do and we want to apply our knowledge and passion to the business environment.

Bueno & Castro Tax Lawyers: Experts in tax efficiency.

We believe that there is no high-quality legal and tax advice without a genuine commitment to the practicality of our advice and conclusions, deep accounting knowledge and permanent technical updating, since tax law – specially in Brazil – changes every day.

Our partners have more than 20 years’ experience in the legal market, acquired in respected law firms, major Big4 audit firms and renowned schools and higher education institutions in São Paulo, New York and Washington D.C. Our experience empowers us to advise clients on cutting-edge topics and be a reference in the tax area and in the specialized media, often featuring in newspapers and broadcasting vehicles.

We have learned that to be seen as business partners and trusted advisors of our clients, we must cherish a transparent, close and pragmatic relationship, with a hands-on approach and always be prepared and available to solve problems that come their way.

We consciously chose the boutique model to enable the high degree of specialization and technical quality worthy of large structures with the speed and character of smaller firms. We make a point of understanding our clients' operations, background and history, presenting different and creative solutions and possible alternatives by measuring all costs and risks involved, both in the tax and accounting areas. We know that in order to solve complex business issues, deep technical expertise must be combined with discernable and didactic solutions, so each job is always conducted personally by one of our partners aimed at presenting the best possible option of client´s problems based on the their own reality, history and goals.

Our international experience and vast knowledge of accounting is testimony to our practice regarding valuable topics that transcend the mere tax burden, but that also generates financial and economic momentum for the business as a whole. Transparent and predictable pricing allows our partners' interests to be aligned with yours, nurturing lasting relationships of trust without the burden of a hourly-rate only solution for determining our legal fees.


Our firm has been recognized as one of the best in Tax Law in Brazil
