The cohort at Advokatfirmaet Thommessen AS has a strong reputation for its abilities advising its client roster on the full remit of complex taxation issues, often in cross-jurisdictional contexts. Its workload incorporates direct tax and property tax matters, as well as advising on the tax aspects of fund establishments, capital markets issues, joint ventures and renewable energy transactions; the team is also noted as ‘one of the leading teams in indirect tax’, an area of expertise of Bjørn Christian Lilletvedt Tovsen. The practice is also equipped to handle contentious cases at various court levels; Finn Backer-Grøndahl advises foreign clients on tax disputes with national authorities. Other key practitioners include Ståle Kristiansen who ’stands out in the field’, and Espen Ommedal, who advises high-net-worth clients on migrations. Marianne Brynjulfsen Overaa has a corporate tax focus, Camilla Hammer Solheim joined the practice from BAHR in September 2024, and Marius Holm Rynning helms the offering.
