Count departure and preceding-year days together
Irish residence can continue in a year with fewer than 183 days because the 280-day two-year test also applies. Review the preceding year and the rule for a current year with 30 days or fewer, rather than relying only on a new overseas residence certificate. Keep records of arrival and departure dates because part-day presence generally counts.
A treaty may resolve dual residence, but it needs a separate factual assessment and does not erase all domestic filing requirements automatically. Any split-year employment treatment is not a blanket exemption for investment income and gains after the flight date. Before agreeing a major disposal, identify the income category, residence result and any ordinary-residence continuation. Build the destination’s residence chronology alongside the Irish one so that overlapping periods and treaty positions can be explained consistently.
Ordinary residence can continue for three tax years
Someone who has become ordinarily resident generally remains so for three tax years after leaving. Revenue’s stated exceptions include a wholly foreign trade or profession, employment with all duties performed abroad, and certain foreign income not exceeding €3,810. The treatment is therefore more specific than “all worldwide income stays taxable” or “nothing is taxable after departure.”
Domicile and the remittance rules can add another layer. Before distributing accumulated foreign profits or selling an investment portfolio, establish whether the receipt is income or a gain, where it arises, and which residence/domicile rules remain applicable. Preserve old account records and evidence of capital rather than mixing funds immediately before moving. The departure advice should cover each relevant tax year and the expected transactions in it, including an earlier-than-planned return to Ireland.
Maintain evidence of the continuing Irish connections
A departure plan should identify Irish property, directorships, employment days and business activity retained after the move. A foreign-incorporated company managed from Ireland does not become nonresident simply because a new address is registered abroad; actual control must match the proposed result. An Irish-incorporated company also has its own residence and treaty analysis independently of the shareholder.
Complete the final and continuing returns, update banks with accurate tax residence and identification numbers, and preserve the records supporting remittance tracing and the end of ordinary residence. Consider the immigration consequences of absence if retaining permission or later pursuing citizenship matters. The first destination return should use facts consistent with the Irish departure file. Before returning for substantial periods, retest the day counts and company-management position rather than treating the original departure as permanent protection.
