# Ireland Tax Residence Tax residency rule, Ireland. Page: https://usecountr.com/trackers/tax-ie/ ## Summary You are tax resident in Ireland for a year if you are present there for 183 days or more in that year, or for 280 days or more in that year and the year before together. The tax year is the calendar year. Any part of a day counts as a day. A year with 30 days or fewer never makes you resident and adds nothing to the 280-day test. A resident who is also domiciled in Ireland is taxed on income from the whole world. Revenue, the Irish tax authority, applies the rule. - Limit: 183 days in one year, or 280 days over two years - Period: The calendar year, 1 January to 31 December - A day counts when: You are in Ireland at any time during that day - Safe floor: 30 days or fewer in a year: not resident for that year - Law: Taxes Consolidation Act 1997, section 819 - Run by: Revenue (the Irish Revenue Commissioners) ## Who it applies to - People who move to Ireland for work and need to know from which year they are resident. - Irish people who moved abroad and still spend long periods at home each year. - People who divide their time between Ireland and another country, such as the UK. - Remote workers and contractors who visit Ireland often and want to stay non-resident. ## The rule Section 819(1) of the Taxes Consolidation Act 1997 has two day tests. You are resident for a tax year if you are present in the State for at least 183 days in that year. You are also resident if you are present for at least 280 days in that year and the year before together. Revenue calls the second test the look-back rule. The State here means the Republic of Ireland, so days in Northern Ireland are not counted. Section 819(2) limits the look-back rule. If you are present for 30 days or fewer in a tax year, you are not resident for that year, and those days are ignored in the 280-day test. So the look-back rule can only make you resident when both years have more than 30 days. Section 819(4) says you are present for a day if you are in the State at any time during that day. Arrival days and departure days both count. Section 819(3) lets you choose to be resident in the year you arrive, if you can show Revenue that you are in Ireland with the intention to be resident in the next year too. The choice is made in writing and cannot be taken back. People mostly use it to get full tax credits in the first year. Two other ideas sit beside residence. Ordinary residence (section 820) follows your pattern over several years: after 3 tax years in a row as a resident you are ordinarily resident from the start of the fourth year, and you only lose that after 3 years in a row as a non-resident. Domicile is the country that is your permanent home in law. Together with residence, these decide how much of your foreign income Ireland can tax. The day count gives the answer under Irish law only. If another country also treats you as resident, the tax treaty between Ireland and that country has tie-breaker tests that decide where you are resident for the treaty. Why it exists: Ireland uses a pure day count so that residence is simple to check and hard to argue about. The 183-day test catches people who spend most of a year in the country. The 280-day test over two years stops a person from staying just under 183 days every year while living mostly in Ireland. The 30-day floor protects short visits. The state wants people who really live in Ireland to pay Irish tax on their income, also when they travel a lot. ## Counting the days You count the days you are present in Ireland in a calendar year. Any part of a day in the country is one day, also when you land late at night or leave early in the morning. 1. Take the calendar year you want to check, from 1 January to 31 December. 2. Count each day on which you were in Ireland at any time, including the day you arrived and the day you left. 3. If the total is 30 or fewer, stop: you are not resident for that year under the day tests. 4. If the total is 183 or more, you are resident for that year. 5. If it is between 31 and 182, count the year before in the same way. If that year has more than 30 days and the two totals together are 280 or more, you are resident. How Countr counts it: Countr counts every day on which your evidence shows you in Ireland, in each calendar year, because any part of a day counts. The tracker shows 182 as the limit, the last day before the 183-day test makes you resident, and warns you 14 days before. It also works out the two-year test: your days this year plus last year against 280, and it leaves a year with 30 days or fewer out of that sum. Both tests use your recorded travel only. If your history has gaps, the result can stay open, and the count runs up to the date you pick, not to the end of the year. Countr does not take out airside transit or days when you could not leave for reasons outside your control. It does not look at ordinary residence, domicile or treaty relief. ## Examples ### Resident through the two-year test Liam works for a company in Dublin and lives partly in Spain. In 2025 he is in Ireland on 150 days. In 2026 he is there on 135 days. Neither year reaches 183. But both years have more than 30 days, and 150 plus 135 is 285, which is over 280. Liam is resident in Ireland for 2026. He is not resident for 2025 unless 2024 and 2025 together also reach 280. ### A short year that protects you Sofia lived in Cork for most of 2025 and was present on 255 days. She moved to Canada in January 2026 and came back only for two visits, 28 days in total. The two years add up to 283 days. That does not matter: with 30 days or fewer in 2026 she is not resident for 2026, and those 28 days are ignored. She can still be ordinarily resident, which is a separate rule. ### The late arrival that adds a day Tom plans 182 days in Ireland in 2026 and counts nights. His last flight lands in Dublin at 23:30 on 9 December, and he counted that stay from 10 December. Ireland counts any part of a day, so 9 December is a day of presence. His real total is 183 days. He is resident for 2026, and the 30 minutes before midnight made the difference. ## Exceptions - Airside transit: you are not treated as present while you arrive and leave and stay the whole time in a part of an airport or port that is closed to the public. - Force majeure: if you cannot leave on your planned day because of extraordinary natural events or a failure of a third party that you could not foresee or avoid, such as severe weather or a broken aircraft, the day after your planned departure is not counted. - Split-year treatment (section 822): in the year you arrive or leave for good, your employment income can be taxed as if you were resident for only part of the year. It applies to employment income only. - Election to be resident (section 819(3)): you can choose to be resident in your year of arrival, in writing, when you will be resident in the next year. - Ordinary residence: after you leave, you stay ordinarily resident for 3 tax years and can still be taxed on some foreign income, but not on other foreign income of 3,810 euro or less, and not on work done fully abroad. - Tax treaties: a double taxation agreement can decide that you are resident in the other country for the treaty, even when you meet the Irish day test. ## Common misconceptions - "If I stay under 183 days every year, I am never resident in Ireland." The look-back rule adds two years together. With 140 days this year and 140 last year you have 280 days, and you are resident for this year. - "A day only counts if I sleep in Ireland." Any part of a day counts. A morning flight out or a late landing each makes a day of presence. Counting nights gives you a total that is too low. - "Once I am non-resident, Ireland cannot tax my foreign income." If you were resident for 3 years in a row, you stay ordinarily resident for 3 more tax years after you leave. In those years some foreign income, such as investment income above 3,810 euro, can still be taxed in Ireland. - "The Irish tax year starts in April, like in the UK." The Irish tax year is the calendar year, 1 January to 31 December. The days are counted inside that period. ## Questions and answers ### Does the day I arrive in Ireland count as a day for tax residence? Yes. You are present for a day if you are in Ireland at any time during it. The day you arrive and the day you leave both count as full days. ### How does the 280-day rule work in Ireland? Add your days in the current year to your days in the year before. If the sum is 280 or more, you are resident for the current year. A year with 30 days or fewer is left out, so both years must have more than 30 days. ### Do days in Northern Ireland count for Irish tax residence? No. The test counts presence in the State, which is the Republic of Ireland. Days in Belfast or Derry are days in the UK and are not counted for the Irish test. ### What happens if I am in Ireland for exactly 183 days? You are resident for that year. The law says at least 183 days, so 182 days is the most you can spend without meeting the one-year test. You still have to check the 280-day test. ### Do I count a stop at Dublin Airport between two flights? Not if you stay airside for the whole stop, in the part of the airport that the public cannot enter. If you pass through arrivals and go into the country, the day counts. ### Can I be tax resident in Ireland and in another country in the same year? Yes, because each country uses its own test. When that happens, the tax treaty between the two countries has tie-breaker tests, starting with where your permanent home is, to decide your residence for the treaty. ## Sources - [Revenue, How to know if you are resident for tax purposes](https://www.revenue.ie/en/jobs-and-pensions/tax-residence/resident-for-tax-purposes.aspx) - [Revenue, How to know if you are ordinarily resident for tax purposes](https://www.revenue.ie/en/jobs-and-pensions/tax-residence/ordinarily-resident-tax-purposes.aspx) - [Revenue, Tax and Duty Manual Part 34-00-01, residence of individuals (sections 819 to 822)](https://www.revenue.ie/en/tax-professionals/tdm/income-tax-capital-gains-tax-corporation-tax/part-34/34-00-01.pdf) - [Revenue, Moving to or from Ireland during the tax year](https://www.revenue.ie/en/jobs-and-pensions/tax-residence/moving-to-from-ireland.aspx) --- Countr is an app for iPhone that counts your days in every country for visa, tax and residency rules, from the photos on your phone and your location.
