Irish pensions and PRSAs: US tax issues

Irish pensions come with generous Irish tax breaks, but the US–Ireland tax treaty doesn't clearly extend them to your US return, so an American in Dublin needs to know what the IRS may tax, what to report and where PFIC risk hides.

The short version

Ireland gives income tax relief at your marginal rate on pension contributions, up to an age-based percentage of earnings capped at EUR 115,000 (about USD 128,400) [1][3].
Auto-enrollment arrived on January 1, 2026. Employees without a workplace pension may be put into MyFutureFund, with employer and state top-ups [5].
The US doesn't automatically recognize Irish pension tax breaks. The treaty's saving clause lets the US tax its citizens, and the treaty has no provision on growth inside a pension plan [6].
Funds inside an Irish pension can be PFICs, although a treaty pension-fund exception may apply in some cases [8].
Reporting still applies: FBAR and Form 8938 obligations aren't switched off by the IRS's 2020 foreign retirement trust relief [7][9].

USD conversions use the Federal Reserve H.10 rate of October 30, 2026 (EUR 1 = USD 1.1163).

Think of Irish pensions as roughly parallel to the US system: workplace plans like a 401(k) or a traditional pension, plus personal accounts like an IRA.

Irish product	Closest US idea	Key points
Occupational pension (defined benefit or defined contribution)	Company pension or 401(k)	Set up by your employer for its staff [4]
AVCs (Additional Voluntary Contributions)	Extra 401(k) deferrals	Top up an occupational scheme [2]
PRSA (Personal Retirement Savings Account)	IRA	Portable personal pension; you keep it when you change jobs and can switch providers free [4]
RAC (Retirement Annuity Contract)	Solo 401(k) or IRA for the self-employed	Personal pension, often for the self-employed [2]
PEPP (Pan-European Personal Pension Product)	No real equivalent	EU-wide personal pension that qualifies for relief [2]
MyFutureFund	A state-run auto-IRA	Auto-enrollment scheme since January 1, 2026 [5]

PRSAs in more detail

A PRSA comes in two flavors [4]:

Standard PRSA: charges are capped, and it invests only in pooled funds.
Non-Standard PRSA: uncapped charges and wider investment choices.

Employers without an occupational scheme must give employees access to at least one Standard PRSA, and you can use any authorized provider instead [4]. Providers can't demand a minimum contribution above EUR 300 a year (about USD 335) [4].

MyFutureFund

You're automatically enrolled if you don't pay into a pension through payroll, you're aged 23 to 60, and you earn EUR 20,000 or more a year (about USD 22,300) across all jobs [5]. For every EUR 3 you put in, your employer adds EUR 3 and the state adds EUR 1 [5]:

Scheme years	You	Employer	State
1 to 3	1.5%	1.5%	0.5%
4 to 6	3%	3%	1%
7 to 9	4.5%	4.5%	1.5%
10 and after	6%	6%	2%

Employer and state contributions stop at EUR 80,000 of salary a year (about USD 89,300) [5]. There's no tax relief on MyFutureFund contributions; the state top-up replaces it [5]. You can opt out in a two-month window after six months, and if you move abroad, you stay enrolled with your savings still invested [5].

The Irish tax breaks

Contributions to approved schemes get income tax relief at your marginal rate, 20% or 40%, but no relief from USC or PRSI [2][3]. The annual limit depends on your age [1]:

Age	Max. relieved contributions (% of earnings)
Under 30	15%
30 to 39	20%
40 to 49	25%
50 to 54	30%
55 to 59	35%
60 or over	40%

Earnings above EUR 115,000 don't count, and employer contributions don't use up your limit [1]. The overall cap on a tax-relieved fund, the Standard Fund Threshold, is EUR 2.2 million (about USD 2.46 million) in 2026 [3].

At retirement, Ireland lets you take a tax-free lump sum of up to EUR 200,000 (about USD 223,300) in total; the next slice up to EUR 500,000 is taxed at 20%, and anything above at your marginal rate [3].

How the IRS sees it

This is where Americans get tripped up. A 401(k) gets US tax deferral because the tax code says so. An Irish pension gets Irish deferral because Irish law says so. Neither country's breaks carry over automatically.

Contributions

The US–Ireland treaty has a pension-contribution rule, but it's narrow: it covers someone who was already contributing to a home-country plan just before going to work in the other country, for up to five years in total, and only if the competent authority agrees the plan corresponds to a recognized one [6]. Think of an American on a short assignment who keeps paying into a US plan. It doesn't give a long-term American resident a US deduction for joining an Irish plan.

So, as a general rule, your own contributions to an Irish pension may not reduce your US taxable income, and employer contributions may count as US income depending on the plan and when your rights vest. With Ireland's high tax rates, the foreign tax credit often absorbs any extra US tax on salary, but not always.

Growth inside the plan

The treaty contains no provision on investment growth inside a pension plan [6]. Whether the IRS taxes that growth each year, or only when you take money out, depends on how the plan is classified for US purposes, for example as an employees' trust or as an account you're treated as owning directly. That's a technical call for a cross-border preparer.

Payouts

The treaty's saving clause lets the US tax its citizens as though the treaty didn't exist, with listed exceptions [6]. Irish tax paid on a pension can generally be credited against US tax on the same income [6]. The Irish tax-free lump sum is a common trouble spot: tax-free in Ireland doesn't necessarily mean tax-free in the US.

PFICs and reporting

The PFIC question

A foreign mutual fund or ETF is usually a passive foreign investment company, with punishing US tax rules and Form 8621 [8]. Irish pension funds typically hold exactly those kinds of funds.

There is some relief. The Form 8621 instructions say an arrangement treated as a foreign pension fund under a US income tax treaty can exempt members from completing Part I for PFICs held through it, with details in Regulations section 1.1298-1(c)(4) [8]. Whether your Irish plan fits depends on the treaty and the plan, so ask your preparer. A Non-Standard PRSA where you pick individual Irish-domiciled ETFs is where the PFIC risk feels most real.

Forms to know

Form	Applies to an Irish pension?
FBAR (FinCEN Form 114)	Due April 15, with an automatic extension to October 15, when foreign accounts top USD 10,000 [9]. The FBAR excludes accounts held in a retirement plan you participate in, but doesn't spell out how that applies to foreign plans [9]
Form 8938	Not affected by the trust relief below [7]; check with your preparer
Forms 3520 and 3520-A	Not required for qualifying tax-favored foreign retirement trusts under Revenue Procedure 2020-17 [7]
Form 8621	For PFICs, subject to exceptions [8]

Revenue Procedure 2020-17 exempts eligible US individuals from Forms 3520 and 3520-A for tax-favored foreign retirement trusts that operate mainly to provide retirement benefits, accept contributions only from earned income, limit contributions (for example to USD 50,000 a year or USD 1,000,000 lifetime), restrict early withdrawals and report to the local tax authority [7]. Whether your particular Irish plan meets every condition is something your preparer should confirm.

What to do

Before you join or open anything, list what's on offer: occupational scheme, PRSA or MyFutureFund.
Ask your employer for the scheme documents, including how contributions vest.
Prefer pooled funds you can document, and keep annual statements showing contributions and values.
Talk to a US expat tax preparer who knows Irish pensions, before your first April with Irish contributions.
Keep your US accounts in mind. Many Americans keep saving in a 401(k) or IRA where they can; our 401(k) guide covers the catches.
Watch the new investment account. Budget 2027 announced a new Irish investment account from July 1, 2027, with a EUR 50,000 tax-free threshold and a EUR 12,000 annual contribution limit [10]. Funds inside may raise the same PFIC questions, so check before you sign up.

All of this is general information, and a US expat tax preparer (or lawyer) can check your situation. To compare notes with others who've been through it, try our community group for Americans in Ireland.
