Irish residence can arise at 183 days in one tax year or 280 days across two years, subject to the 30-day qualification. Any part of a day generally counts, with airside and unavoidable-delay exceptions.
The rule
Ireland also has a separate 280-day test across the current and previous tax years. This counter does not calculate that second route, domicile, ordinary residence, elections, or treaty outcomes.
Counting the days
Recorded part-days, including arrival and departure, count.
- Choose the date through which you want to count, then add your recorded visits.
- Use the counting convention above. Overlapping recorded dates in the relevant region are counted only once.
- Read the result alongside the conditions. Missing records and other eligibility requirements are not inferred from a total.
Examples
These examples demonstrate the counter's arithmetic, using a count-through date of 30 October 2026. They do not determine legal status or eligibility.

Common misconceptions
“A count below the day threshold settles tax residence.”
A recorded-day total is one component. Review the separate conditions and exceptions described on this page.
“The window follows the latest twelve months.”
This counter uses the calendar year. A rolling window and a calendar year can produce different totals.
