Questione giuridica chiave
Whether the shareholder loan interest had to be adjusted as a hidden profit distribution under the arm's-length principle and the ESTV circular.
Decisione estratta
Yes. The taxpayer did not prove that the 0.25% interest corresponded to market conditions; the circular applied, and the correction was justified.
Motivazione estratta
The circular was not binding law but a valid administrative guideline. The company failed to show that the loan to the shareholder would have been granted on the same terms to an unrelated third party. No written agreement, no amortization plan, no security, and unpaid interest supported the conclusion that the arrangement did not withstand a third-party comparison.
