  • Counsel in Supreme Administrative Court Case Confirming Real Estate Investor’s Right to Deduct VAT on Transaction Expenses

  • Counsel to a tax payer receiving confirmation in a court that a transfer of a business at an early stage qualifies as a transfer of a going concern for VAT purposes.

  • On 12 February 2019, the Finnish Supreme Administrative Court issued a resolution concerning the VAT treatment of intermediary services to Finnish students aiming to study abroad in the U.S. Piia Ahonen successfully defended the client’s position through instances, and the resolution issued by the Supreme Administrative Court as a yearbook decision finally confirms that the client’s position is right and that the tax assessments were unlawful. The intermediary services are not subject to Finnish VAT due to the fact that the client acted as an intermediary between U.S. schools and Finnish students in relation to U.S.-based education and accommodation services that are not taxed in Finland.
