Norway’s Supreme Court upheld the Court of Appeal’s ruling that discretionary income assessment under section 13-1 of the Tax Act in thin capitalisation cases must be based on a net assessment of the entire transaction, allowing interest margins on intra-group loans within borrowing capacity to be adjusted upwards in the taxpayer’s favour. The State’s appeal was dismissed and it was ordered to pay costs of NOK 2,000,000 to Orlen Upstream Norway AS.
