Tax residency in Ireland
An individual is tax resident in Ireland for a tax year if present in the State for 183 days or more in that year, or for 280 days or more in aggregate in that year and the preceding year, provided the individual is present for at least 30 days in each of those two years; a year with fewer than 30 days’ presence is disregarded for the two-year aggregation. Ordinary residence arises after being resident in Ireland for three consecutive tax years and continues until the individual has been nonresident for three consecutive tax years, with commencement and cessation applying from the start of the fourth year. Domicile is a separate concept from residence. Where an individual is resident in Ireland and another jurisdiction under domestic rules, any applicable double tax treaty tie-breaker (generally considering permanent home, centre of vital interests, habitual abode, and nationality, and if needed mutual agreement) determines treaty residence.
