Hannes Snellman assisted the client in an advance ruling process to confirm that certain services acquired regarding the target investment were considered VAT exempt management services of special investment funds and that the client did not have to pay VAT under the reverse charge mechanism. The matter was important to the client, as in practice it may vary what kind of services are needed to be acquired when acting as a lead investor or co-investor joining an investment at a later stage. The services in question formed a sufficient bundle of services qualifying for the criteria of VAT exempt financial services necessary for the client to be able to make the investment decision and similar investments in a more efficient way in the future as well. The Finnish tax authorities’ first opinion was that the services were VATable, but Hannes Snellman’s VAT team was able to change the outcome during the advance ruling process. The ruling is now final.

Counsel a real estate company in a case regarding the VAT deduction of real estate investments. The Finnish Tax Administration had not accepted the VAT deductions made by the company because it had found that the premises were used for both VAT taxable and VAT exempt activities. In the case, it was evaluated from the VAT perspective how the leasing area can be determined per floor of the building while also considering how the premises are described in the articles of association.

Assisted by Hannes Snellman's tax team, the company appealed the Tax Administration’s decision to the Administrative Court and was able to prove that the premises were mostly used for purposes entitling to a VAT deduction, wherefore the company had had the right to deduct the VAT of the costs related to these premises that were used for VATable purposes. The company won the case in the Administrative Court, after which Hannes Snellman assisted the company with the preparation of corrective VAT returns and the refund of VAT that had been groundlessly left unrefunded.
