Abreu Advogados is the law firm set to provide legal advice in a new society, working daily to ensure that for new industries, new ideas are created; for new pressures, new solutions are planned and for new challenges, new answers are provided.

A full-service law firm with offices in Lisbon, Oporto and Funchal (in partnership) and a network of associated law firms in Portuguese speaking jurisdictions, Abreu Advogados is amongst the largest law firms in Portugal.

With a professional management structure committed to creating a client-oriented culture, Abreu Advogados was the first law firm in Portugal to certify its quality management system under the European ISO 9001 standards and is now at the forefront of ESG practices in Portugal.

Tax law is the firm’s DNA. Abreu Advogados’ tax team is one of the largest, most highly-skilled and most senior tax teams in Portugal. It has a track record in transactional tax, international taxation, indirect taxation, complex litigation, transfer pricing and private wealth taxation. Abreu Advogados' tax team has a long-standing client database, addressing the most diverse areas, while always investing in new areas of tax law. Its involvement in climate change taxes, renewable energy taxation, digital assets and blockchain technology taxation and recently the new EU taxes for 2023-2027, have considerably boosted its position in the market.

Given the range of areas in which the lawyers are experts, as well as the inherently innovative nature of the matters which they deal with, the firm often teams up with some of the largest international law firms. Together they handle some of the largest and most complex tax-related transactions of the new circular and digital economy, assisting prominent families and family offices and taking on tax litigation, shaping both tax law and tax authorities’ regulations and practice.
