Major High Court judgment on tax appeal to be closely watched

Perrigo wants the court to quash the 2018 assessment raised against it after a Revenue audit in 2016.

A High Court judge will give judgment next week on a significant action by drug company Perrigo against the Revenue and State aimed at overturning a €1.64 billion tax assessment.

Mr Justice Denis McDonald’s decision next Wednesday could have significant implications well beyond Perrigo and the hearing was closely monitored by large companies and tax consultants. Irish-headquartered Perrigo, which bought Irish pharm group Elan in 2013, wants the court to quash the 2018 assessment raised against it after a Revenue audit in 2016.
