Ex officio taxation: No “surprise” income without prior notice of adjustment
In its judgment of 8 May 2026, the Court of Cassation reaffirmed an important limitation on the tax authorities’ power to impose an assessment ex officio: where a taxpayer is assessed ex officio for failing to respond to a notice of adjustment, the assessment may only be based on income already identified in that notice. The tax authorities cannot introduce additional income that the taxpayer has never had an opportunity to challenge.
