Irons, who has been married to Irish actor Sinéad Cusack since 1978 and owns Kilcoe Castle in County Cork, had previously expressed a desire for Irish citizenship.
Sinéad Cusack revealed that the process would require a 'very extreme rethink of all his tax situations,' leading him to abandon the application.
Following Brexit, there has been a record increase in UK residents applying for Irish passports, with 242,772 applications in 2024.
Irons' adult children, Samuel and Max, are eligible for Irish passports through their mother, Sinéad Cusack, who is fully Irish.
