🇮🇪 Tax residency in Ireland

Irish tax residency is a day-count test, and it has two triggers. The first is the familiar one: spend 183 days or more in Ireland in a tax year and you are resident for that year. The second is the one that catches serial visitors: 280 days combined across the current and preceding tax year also makes you resident, provided you spent at least a minimal presence in the current year. So two consecutive "safe-looking" stays of around 140 days each can still add up to Irish residency. If you are splitting the year between Ireland and elsewhere, count both years, not just the current one.

Ireland does not use a vague ties-based test to pull you in below those counts; the statutory day counts are the test. What days spent elsewhere do affect is your position in a dual-residence dispute with another country, which is resolved under whatever treaty applies.

If you become resident, Ireland taxes worldwide income by default. The top marginal income tax rate is 40%, and the Universal Social Charge and PRSI come on top of that, so the effective burden on higher earnings is meaningfully above the headline rate.

The reason Ireland stays on nomad shortlists anyway is the non-domiciled remittance basis. If you are Irish-resident but not Irish-domiciled (most foreigners are not), foreign income is only taxed if you remit it: bring it into Ireland or use it there. Income earned from foreign clients and kept offshore, invested abroad, or spent outside Ireland generally escapes Irish tax. Money you transfer to an Irish account or use to cover Irish living costs is taxable. It shelters what stays out, not what you live on locally.

On treaties: Ireland has an income tax treaty in force with the United States, which provides credit relief so the same income is not taxed twice; US citizens still file US returns wherever they live. Ireland also has treaties with the UK and Germany. Which country gets primary taxing rights depends on the income type and your residency facts, so check the specific treaty text on the Revenue Commissioners' treaty list rather than relying on a general summary.

Professional advice makes sense in specific situations: you plan to use the remittance basis (the remittance rules have traps around mixed funds and credit cards), you have income from several countries, you have Irish clients or an Irish entity, you own property, or your residency straddles two countries and a treaty tie-breaker is in play. Those are the cases where a mistake costs real money.

Ireland taxes residents on worldwide income unless you qualify for and correctly operate the remittance basis, which shelters foreign income not brought into the country.
