Tax and Duties

Thommessen has for a number of years been awarded a top ranking in tax law. Our lawyers assist Norwegian and multinational clients in a broad range of industries on Norwegian and international tax matters and in disputes with the Norwegian authorities.

Tax law is characterised by internationalisation, a changing world economy and technological developments. Norwegian tax law has become more complex and is increasingly affected by international legal developments. An inadequate understanding of applicable regulations may have major repercussions for businesses. We provide clear and practical advice, thereby enabling our clients to attain their commercial objectives in the most effective manner.

With more than 20 lawyers, Thommessen has one of Norway’s very largest and most experienced tax teams. We cover all tax law practice areas, with a focus on transactions, the equity and debt markets, joint ventures, fund establishment, real estate, renewable energy, shipping, as well as oil and gas. We assist a range of clients, from major listed multinationals and international private equity funds to venture capital companies and seed capital companies. Our lawyers assist in disputes with the Norwegian tax authorities and litigate a considerable number of tax matters before the Norwegian courts, including the Supreme Court.

They have a very competent team with great depth and breadth. Client
