Who taxes you?
As a US citizen working in Ireland, you're subject to taxation by both countries. The US taxes citizens on worldwide income, but the Foreign Earned Income Exclusion (FEIE) can exclude up to $132,900 of foreign earned income in 2026 if you meet the 330-day physical presence test. Ireland taxes residents who are also Irish domiciled on their worldwide income, with progressive rates up to 40%, plus Universal Social Charge (USC). If you are resident in Ireland but not domiciled there (domicile broadly means the country you intend to live in permanently, and you keep your domicile of origin unless you choose a new one), foreign income such as US interest and dividends is taxed in Ireland only when you bring it into Ireland. Pay for work you do in Ireland is taxed in full either way. The US-Ireland tax treaty provides foreign tax credits to prevent double taxation.
Common pitfalls
- Irish tax rates are high, with top marginal rate of 40% plus USC
- Universal Social Charge (USC) adds additional tax on top of income tax
Is there a US-Ireland tax treaty?
Yes. The US-Ireland income tax treaty is in force, and foreign tax credits cover what it does not.
Getting paid in Euro
Salaries in Dublin are paid in Euro (EUR). A 100,000 US-dollar salary is roughly 92,000 EUR at current rates. That matters twice over: your US return is always filed in dollars, so the rate on each payday feeds straight into what you report, and a currency that moves against the dollar changes what the same nominal salary is worth to you without your pay changing at all.
Frequently asked questions
Not on the same income: a treaty is in force. You pay the higher of the two rates, not both.
The Euro (EUR). A 100,000 US-dollar salary is about 92,000 EUR at current rates. Your US tax is always calculated in dollars, so the exchange rate on the day you are paid feeds directly into what you report, and into how far the same nominal salary goes in Dublin.
Ireland has a progressive income tax system with rates of 20% and 40%, plus Universal Social Charge (USC) which adds additional tax on top of income tax. You can claim foreign tax credits on your US return to offset taxes paid to Ireland.
The USC is an additional tax in Ireland that applies on top of income tax. Rates vary from 0% to 8% depending on income level, with progressive brackets. It's separate from income tax and social insurance contributions.
