Janne Juusela

Partner, Member of the Finnish Bar, Ph.D. (Law)

I have over 20 years of experience in advising companies on tax matters. I have provided comprehensive advice to both domestic and international companies from all fields of business. In addition to publicly listed companies, I have assisted several family-owned companies and their owners. I specialise in corporate taxation, international tax law, mergers and acquisitions, and tax litigation.

Prior to joining Castrén & Snellman, I was a partner and head of tax practice in another Finnish law firm. I have also worked as a tax specialist in an international auditing company. In the early days of my career, I worked for the Ministry of Finance preparing tax laws.

I defended my doctoral thesis on tax law in 1998, and since 2002 I have been an adjunct professor of tax law at the University of Helsinki. I have authored several books and articles on taxation, and I am a co-author of ‘Corporate taxation I-II’, a cumulatively supplemented handbook on tax law.

Chambers Europe, The Legal 500, Who’s Who Legal, International Tax Review and Best Lawyers rank me among Finland’s leading tax experts.

We act as the lead legal counsel in the groundbreaking case of Multitude SE’s (Multitude) proposed relocation from Finland to Switzerland. The first phase of the relocation, involving the transfer of Multitude’s registered office from Finland to Malta pursuant to SE Regulation, was successfully completed on 30 June 2024. In this connection, Multitude’s shares were removed from the Finnish book-entry system and the issuer central securities depository of the shares changed from Euroclear Finland Oy to the CSD operated by the Malta Stock Exchange. In practice, all of Multitude’s shares are now held through Clearstream. In Malta, the company is anticipated to be converted into a public limited liability company under Maltese law, following which it will seek redomiciliation from Malta to Switzerland. Given that Finnish legislation does not allow for direct relocation to a non-European Economic Area country such as Switzerland while preserving the company’s legal personality, the process necessitated a multi-jurisdictional strategy as outlined above. Our mandate encompasses advising Multitude on all aspects governed by Finnish law concerning the proposed relocation and coordinating the work of local legal counsel and various other advisors involved in the project. The process also involved a written procedure to amend Multitude’s existing subordinated capital notes and senior bonds to facilitate the relocation as well as placement of EUR 80 million senior guaranteed notes by a newly established Multitude Capital Oyj. ”The transfer to Malta marks a significant step in Multitude’s journey. This pioneering and complex process has been successfully implemented with the invaluable support of our own team and advisors. Castrén & Snellman has masterfully orchestrated the entire project, ensuring seamless coordination across multiple jurisdictions. We look forward to achieving our next step with the further relocation to Switzerland”, says Jorma Jokela, Multitude’s CEO. Multitude is a fully regulated growth platform for financial technology, employing over 700 individuals across 25 countries. Its shares are listed on the regulated market (Prime Standard) of the Frankfurt Stock Exchange.

We assisted a very wealthy private individual in a large-scale tax dispute that concerned expatriation. The tax authorities reviewed the taxation of the private individual through a subsequent assessment, arguing that the final preliminary ruling on the individual’s expatriation could be disregarded as subsequent assessment showed that some of the future plans included in the application had not been realised. The reassessment of taxation carried out by the Tax Administration led to significant residual taxes for the individual. A key issue in the tax dispute was whether genuine expatriation could be subject to the tax avoidance regime.
