Ireland Tax Residency Calculator
Ireland has two day-count routes to tax residency: 183 days this year, or 280 days across this year and last combined (with at least 30 this year). Enter your stays once — the tool works out both year counts and applies both tests. The full rule guide covers what residency actually costs you.
1 · Your days in Ireland
Add your stays in Ireland across this year and last. Since 2009, being present for any part of a day counts as a full day — arrival and departure days included.

The lookback is the trap
Most people watch the 183-day line and miss the two-year one. The patterns that get caught:
- Steady commuting — 140 days a year, every year, is resident from year two onward (140 + 140 = 280).
- A heavy year followed by a "light" one — 200 days last year means just 80 this year triggers the lookback.
- The recovery move — after a heavy year, staying under 30 days for a full calendar year is the only guaranteed reset.
Since 2009 any part of a day counts — including a late-evening arrival — so the old midnight-based planning no longer works.
Frequently asked questions
183 days in the calendar year, or 280 days combined across the current and previous years — but the lookback only applies if you have at least 30 days in the current year. Any part of a day in Ireland counts as a full day.
Add this year's days to last year's. If the total reaches 280 and you have 30+ days this year, you're resident this year — even at, say, 140 days per year, a pattern the 183-day test alone would never catch. Frequent commuters between Dublin and London hit this one constantly.
Yes — fewer than 30 days in a year means you can't become resident that year via the lookback, no matter how heavy the previous year was. 29 days is the hard floor when you're carrying a big prior-year count.
After three consecutive years of residence you become ordinarily resident — and it takes three consecutive non-resident years to shed it. During that tail, Ireland can still tax most of your worldwide income (with exceptions for foreign employment income and small investment income), so leaving Ireland is a three-year project, not a one-year one.
