# Ireland Tax Residence and Foreign Income

Irish tax residence, ordinary residence and domicile are separate tests. Together they affect the treatment of Irish and foreign income.

Scope: Baseline individual income-tax context, not an assessment of domicile, treaty entitlement, remittance-basis eligibility or a special relief.

Jurisdiction: Ireland: individual income tax. Sources reviewed 2026-09-17; review due 2026-12-16.

General information, not personal tax advice. Nationality, tax residence and source of income are different questions. Consult the tax authority or a qualified adviser for your circumstances.

## Annual and two-year day tests

Tax residence normally follows 183 or more days in a calendar year, or 280 or more across that year and the preceding year. A year with 30 days or fewer does not make you resident under these tests.

## How days are counted

Any part of a day normally counts. Revenue describes exceptions for staying airside and certain unavoidable departure delays. An arrival-year residence election is a separate, conditional option.

## Residence and domicile together

A person who is both resident and domiciled in Ireland is generally taxed on worldwide income, subject to applicable treaty relief. Residence alone is not a complete description of every person's foreign-income treatment.

## Obligations can continue after departure

Three consecutive resident tax years establish ordinary residence from the fourth year. It continues for three tax years after leaving, potentially extending income-tax obligations; Revenue lists exceptions for particular foreign income.

Evidence: conditional. [Irish 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). Source location: How to know if you are ordinarily resident for tax purposes.

## Irish income can remain taxable

Someone neither resident nor domiciled can still owe tax on Irish-source income and foreign employment income for duties performed in Ireland. Ordinary residence and domicile must also be checked rather than treating departure as automatic exemption.
