US Taxes for Americans Living in Ireland
Ireland has emerged as one of the most popular European destinations for US tech professionals, Google, Meta, Apple, and dozens of other US multinationals base their European headquarters in Dublin. For US citizens in Ireland, the US-Ireland tax treaty is robust, and Ireland's relatively moderate income tax rates make the Foreign Tax Credit the standard approach. But Ireland's tax system has unique features, the remittance basis for non-domiciled residents, PRSI (social insurance), and USC (Universal Social Charge), that require careful navigation alongside IRS obligations.
Local tax authority
The US-Ireland tax treaty (1997, protocol 1999) covers income tax with treaty rates on dividends (15% portfolio, 5% for 10%+ holdings), interest (0%), and royalties (0%). The treaty includes a Savings Clause for US citizens and specific provisions for government pensions, social security, and teachers. A US-Ireland totalization agreement coordinates Social Security / PRSI contributions.
Ireland-specific complexities
- Ireland's Universal Social Charge (USC) of up to 8% and PRSI (4%) add to income tax rates (up to 40%), creating combined effective rates above 50% for high earners
- Irish non-domiciled residents may elect the remittance basis, taxed only on Irish income and foreign income remitted to Ireland, but this does not affect US worldwide reporting
- Ireland does not have a general wealth tax, but Capital Acquisitions Tax (CAT) on gifts and inheritances is notable
- FBAR applies to all Irish bank accounts (AIB, Bank of Ireland, Permanent TSB, N26 etc.) above the $10,000 threshold
- Irish Capital Gains Tax (CGT) of 33% on most gains is creditable against US CGT, but the rates and holding period rules differ
- Irish pension schemes (PRSAs, occupational pensions) may not receive full treaty protection for US persons
What's different about filing from Ireland
Combined Irish tax rates and FTC
Ireland's income tax runs at 20% (standard rate) and 40% (higher rate), but this understates the true burden. The Universal Social Charge (USC) adds up to 8%, and PRSI adds another 4%, bringing combined effective marginal rates to over 50% for earnings above approximately €70,000. These rates are creditable (at least in part) against US income tax via the FTC. In practice, for most US expats in Ireland earning above the standard rate band, Irish taxes paid fully offset US liability.
The remittance basis and US citizens
Ireland allows non-Irish-domiciled individuals to elect the 'remittance basis' of taxation, meaning only Irish-source income and foreign income actually brought into Ireland is subject to Irish tax. This can be an attractive option for some internationals in Ireland. However, for US citizens, the remittance basis does not affect US obligations: the US taxes worldwide income regardless of whether income is remitted to Ireland or not. US citizens on the remittance basis must still report all worldwide income to the IRS.
Irish CGT and US capital gains
Ireland's Capital Gains Tax (CGT) rate is 33% for most assets (with some exceptions). This can be credited against US capital gains tax via the FTC in the capital gains basket. However, Ireland's definition of a capital gain, holding period rules, and allowable deductions differ from US rules, the same transaction may produce different gain amounts under Irish and US law. We reconcile both calculations to maximize available FTC while correctly reporting gains under each system.

Frequently asked questions about US taxes in Ireland
Should I use FEIE or FTC for my Irish income?
FTC is typically the better choice for US expats in Ireland. Combined income tax, USC, and PRSI often produces effective marginal rates above 50% for higher earners, well above US rates. Using FTC means Irish taxes paid effectively eliminate US income tax liability on Irish income. FEIE could be considered for lower-income expats, but the 5-year revocation bar risk makes FTC the safer long-term approach.
Are Irish USC and PRSI creditable against US taxes?
The creditability of USC and PRSI is nuanced. PRSI contributions to the Irish social insurance system are generally not creditable (they're more akin to payroll taxes than income taxes), but are covered by the US-Ireland totalization agreement (so you don't pay into both Social Security systems). USC's creditability as a foreign income tax is an ongoing area, we apply the most favorable defensible position for your return.
Do Irish bank accounts need to be reported on FBAR?
Yes. All Irish financial accounts, AIB, Bank of Ireland, Permanent TSB, Ulster Bank, Revolut (Irish entity), N26, etc., count toward your FBAR threshold. If the aggregate of all foreign accounts exceeded $10,000 at any point, FBAR is required.
I have an Irish pension (PRSA or occupational scheme), how is it treated for US taxes?
Irish pension schemes are not explicitly addressed in the US-Ireland treaty as treaty-protected pensions in the same way as UK or German pensions. The US tax treatment of Irish pension contributions and growth is complex, contributions may or may not be deductible, and growth may be taxable annually. This is an area where professional guidance is particularly important.
