Prior Adversarial Hearing and the Resistance Test in Tax Assessment Proceedings

Abstract

With order no. 22441/2026, the Italian Court of Cassation clarifies the operational scope of prior hearing and the so-called resistance test in European harmonised tax matters arising from desk audits. The breach of pre-litigation participatory rights results in the invalidity of the assessment notice exclusively if the taxpayer identifies specific, non-pretextual factual elements that, through an ex ante probabilistic assessment, could have yielded an alternative or less burdensome outcome. The tax judge of merit must carry out a retrospective prognosis, avoiding any conflation between administrative allegations and strict judicial burden of proof.

Key Legal Takeaways

  • Harmonised taxes and desk audits: failure to hold a prior adversarial hearing in Value Added Tax (VAT) assessments vitiates the notice only if the taxpayer puts forward factual elements capable of satisfying the resistance test.
  • Ex ante probabilistic review: the court of merit must evaluate the potential impact of the taxpayer's submissions as at the time when the omitted administrative hearing should have taken place, without demanding judicial certainty of a different outcome.
  • Prohibition against substantive downgrading: specific factual circumstances adduced by the taxpayer cannot be dismissed merely because they were subsequently reiterated or examined on the merits during judicial tax proceedings.
  • Burden of specific factual allegation: abstract formal objections do not suffice; the taxpayer must identify concrete facts and documentary elements that could reasonably have steered the tax administration towards a milder assessment.
