Ireland tax residency rules
Threshold: 183 days ยท Day Count ยท Calendar year (Jan 1 โ Dec 31)
Ireland's residency framework has four pieces: residency (day-count based, 183 single-year or 280 two-year aggregate), ordinary residence (3-year sticky), domicile, and the remittance basis available to non-doms.
- 183 single-year OR 280 aggregate over current + prior tax year (with 31-day current-year minimum).
- Any presence on a calendar day counts (since 2009; pre-2009 required midnight presence).
- Non-domiciled Irish residents can use the remittance basis, foreign income taxed only when remitted.
