Can I Keep My US Brokerage Account When I Move to Ireland?

Potentially, yes.

There is no general rule requiring you to move an ordinary US brokerage portfolio to Ireland simply because your residential address changes.

But your broker has its own rules.

Some US firms continue providing services to clients resident overseas.

Others may:

• retain existing accounts but restrict new investments
• stop allowing mutual-fund purchases
• restrict managed accounts
• stop providing investment advice
• limit certain securities
• refuse to open additional accounts
• ask the client to transfer elsewhere

That means two separate questions need answering:

Can I keep the account?

and

Can I continue using the account in the way I want?

They are not always the same thing.

1. Keeping the account is different from keeping every investment

This distinction is important.

Your US brokerage firm may allow the account to remain open.

That does not necessarily mean:

• every existing investment remains suitable
• every security remains available to purchase
• your tax position remains unchanged
• your investment strategy should remain identical

Review the account, investments and tax treatment separately.

2. Check the broker before changing your residential address

Provider policies differ.

Some institutions are comfortable with clients resident in Ireland.

Others are not.

Possible outcomes include:

• full service continues
• account remains open but investment purchases are restricted
• mutual funds become unavailable
• managed portfolio services stop
• new accounts cannot be opened
• trading becomes restricted
• the client is asked to transfer elsewhere

Check the policy before making the move.

3. Do not rely on an old answer from your broker

Cross-border servicing policies can change.

A provider that previously accepted Irish residents may change its compliance policy.

Similarly, restrictions may differ depending on:

• citizenship
• account type
• securities held
• advice relationship
• country of residence

Confirm the current position directly with the provider.

4. Do not close the account until you know what will replace it

This is particularly important for Americans abroad.

Access to:

• US custody
• US-listed investments
• international-friendly providers

can be harder to establish after leaving the United States.

Selling everything and closing the account first can leave you with fewer options.

5. Ireland can tax investments even if the account remains in America

Where you hold the account does not by itself determine where the investment income is taxable.

An Irish resident may need to consider Irish tax on:

• dividends
• interest
• capital gains
• fund distributions

alongside continuing US obligations where they remain a US taxpayer.

The account can remain physically and legally in America while Ireland still has taxing rights over the income and gains.

6. Residence and domicile both matter in Ireland

Ireland distinguishes between:

• residence
• ordinary residence
• domicile

An individual who is Irish resident and domiciled is generally taxable in Ireland on worldwide income, subject to applicable treaty relief.

Someone who is not Irish domiciled can have a different position.

That distinction needs to be established before deciding how foreign investments should be managed.

7. The remittance basis may apply to some non-Irish-domiciled individuals

Certain Irish-resident people who are not Irish domiciled can be taxed on specified foreign income and foreign gains on a remittance basis.

Broadly, this can mean tax arises when relevant foreign income or gains are brought into Ireland.

But the detailed rules matter.

For a US citizen, the position is more complicated because the United States generally continues taxing worldwide income.

Do not build an investment strategy around the Irish remittance basis without specialist advice.

8. Irish citizens returning home should not automatically assume they are non-domiciled

Domicile is a legal concept rather than simply nationality or residence.

Someone born in Ireland may have an Irish domicile of origin.

Whether that domicile has changed during years abroad depends on the facts and intentions.

This can materially change how foreign investments are taxed after returning.

9. US dividends can become Irish taxable income

Dividends from US companies may need to be declared in Ireland once you are Irish resident.

Ireland generally taxes foreign dividends as income.

The amount of Irish tax can depend on:

• your overall income
• applicable tax rates
• foreign withholding
• treaty relief
• foreign tax credits
• domicile and remittance treatment where relevant

The United States may also withhold tax on the dividend.

10. The US-Ireland treaty can help coordinate dividend taxation

The US-Ireland tax treaty contains provisions relating to dividends and double taxation.

That does not necessarily mean the dividend is taxed only once.

Instead, the interaction can involve:

• US withholding
• Irish tax
• foreign tax credits

The relevant withholding documentation should therefore be kept up to date with the US brokerage provider.

11. Ordinary share gains can fall within Irish Capital Gains Tax

Ireland generally applies Capital Gains Tax to gains on disposals of assets, including shares, where the relevant Irish tax rules apply.

The current general CGT rate is 33% for most gains.

Individuals also currently have an annual CGT exemption of €1,270.

But not every investment product falls into the ordinary CGT framework.

That distinction is crucial.

12. Do not assume every ETF receives 33% CGT treatment

This is one of the biggest potential traps.

Ireland has specific rules for certain:

• Irish investment funds
• offshore funds
• ETFs
• collective investment structures

Depending on the fund's domicile and legal structure, returns may fall under Ireland's specialised fund-tax regime rather than normal CGT.

The classification needs to be established before buying or selling the investment.

13. Ireland changed the tax rate for certain investment funds in 2026

From 1 January 2026, the individual tax rate applicable to income and gains from relevant Irish-domiciled investment funds and equivalent qualifying offshore funds was reduced from 41% to 38%.

This regime is separate from ordinary CGT.

That makes fund classification important.

Two investments with similar economic exposure can potentially receive different Irish tax treatment because of their legal structure and domicile.

14. Certain funds can also face eight-year deemed disposal

Ireland's fund regime can impose a deemed disposal at the end of each eight-year period for relevant investments.

That means tax can potentially arise even if you have not actually sold the investment.

The investor may effectively need to calculate a taxable gain at the eight-year point.

This is a major difference from a conventional buy-and-hold share portfolio.

15. Americans have an additional problem with foreign funds

A non-US fund may work well under Irish rules but be problematic under US rules.

Many foreign mutual funds and ETFs can potentially be treated as Passive Foreign Investment Companies, or PFICs, for US taxpayers.

PFIC status can create:

• Form 8621 reporting
• additional tax calculations
• potentially punitive tax outcomes
• greater accounting costs
• extensive record keeping

This makes investment selection for Americans in Ireland unusually complicated.

16. The locally obvious investment can therefore be the wrong one

An Irish adviser may naturally recommend:

• an Irish-domiciled fund
• UCITS ETF
• European mutual fund
• managed fund portfolio

These are normal investment solutions for many Irish investors.

For a US taxpayer, they can potentially create PFIC issues.

Investment advice therefore needs to take the US taxpayer position into account from the outset.

17. US-listed investments can avoid some PFIC problems

US-domiciled shares, funds and ETFs are not generally PFICs simply because the investor lives overseas.

That can make a US brokerage account useful.

But avoiding PFIC status does not mean the investment is automatically tax-efficient in Ireland.

The Irish analysis still needs to consider:

• dividends
• gains
• fund classification
• residence
• domicile
• remittances
• estate planning

18. A US-listed ETF needs Irish analysis before being treated like an ordinary share

Do not assume that because an ETF is US domiciled it automatically receives ordinary 33% CGT treatment in Ireland.

Irish rules concerning offshore funds and equivalent investments are technical.

The legal characteristics of the particular fund should be checked.

For substantial portfolios, obtain Irish tax advice on the intended investment universe before restructuring.

19. Direct shares can sometimes be simpler from a classification perspective

Holding shares directly in companies is different from holding pooled investment funds.

A direct share portfolio may avoid certain fund-classification questions.

But it can bring other issues:

• diversification
• administration
• trading costs
• concentration risk
• portfolio complexity

Tax treatment should not be allowed to produce a poor investment portfolio.

20. Investment structure should balance tax and investment quality

The aim is not:

“Avoid every tax at all costs.”

It is to create a portfolio that balances:

• diversification
• expected return
• risk
• tax
• costs
• simplicity
• accessibility
• regulation
• future residence

A highly tax-efficient portfolio that is badly diversified is not a good financial plan.

21. Keep excellent cost-basis records

Before moving to Ireland, download:

• purchase dates
• quantities
• acquisition prices
• reinvested dividends
• corporate actions
• stock splits
• transfers
• historic statements

Irish and US calculations can require different records.

Do not rely on your US provider retaining everything indefinitely.

22. Selling before or after moving can produce different results

If you are planning to sell a large investment, timing can matter.

Review:

• date of Irish tax residence
• domicile
• accrued gains
• US taxation
• Irish taxation
• treaty relief
• currency
• whether the transaction can genuinely be timed flexibly

Do not trigger a sale simply because you are moving without modelling both sides.

23. Split-year treatment should not be treated as a general investment exemption

Irish split-year treatment primarily concerns employment income in the year of arrival or departure.

Do not assume it automatically shelters:

• dividends
• capital gains
• investment income

Investment disposals around the move require separate analysis.

24. Large concentrated stock positions deserve particular attention

People moving from the US technology or corporate sector may hold substantial employer shares.

That can create:

• investment concentration risk
• large embedded gains
• US tax exposure
• Irish tax exposure
• currency exposure

The decision to diversify should consider both tax and portfolio risk.

Avoid allowing tax concerns to leave an excessive proportion of your wealth in one company indefinitely.

25. RSUs and stock options are different from an ordinary brokerage portfolio

If your US brokerage account contains shares acquired through:

• RSUs
• stock options
• ESPP
• deferred compensation

the analysis may require employment-tax sourcing as well as investment tax.

Where those assets were earned before and after moving can matter.

Specialist tax advice is particularly important.

26. Keep US withholding forms up to date

The brokerage provider needs accurate information about:

• residence
• citizenship
• tax status

The correct tax form depends on the individual's status.

For example, a US citizen generally does not become a non-US taxpayer simply by moving to Ireland.

Do not submit tax documentation based solely on your new Irish address.

27. Americans remain subject to US tax while living in Ireland

US citizens generally remain within the US federal tax system on worldwide income.

That means your US investment portfolio remains relevant to your US return.

Irish tax may create foreign-tax-credit considerations.

The objective should be to coordinate the two returns rather than manage the portfolio as if only one tax system applies.

28. Moving investments to an Irish account can create additional US reporting

An American who opens Irish investment accounts may create additional US reporting obligations.

Potential reporting can include:

• FBAR
• Form 8938
• PFIC reporting

depending on the accounts and investments involved.

Keeping an existing US brokerage account may therefore sometimes offer administrative advantages.

29. Currency matters even if the investments remain in dollars

A US portfolio may continue to be denominated predominantly in USD while your lifestyle becomes euro based.

That creates currency exposure between your assets and future spending.

The answer is not necessarily to convert the entire portfolio to euro investments.

Instead, consider:

• euro emergency cash
• near-term spending
• known property costs
• future retirement withdrawals
• long-term globally diversified assets

30. Avoid making one enormous USD/EUR conversion

Moving country does not require converting every dollar on the same day.

Separate:

• relocation spending
• property money
• emergency cash
• long-term investment capital
• retirement assets

A staged approach can reduce dependency on one exchange rate.

31. Estate planning also matters

US brokerage assets can be relevant to:

• US estate tax
• Irish Capital Acquisitions Tax
• beneficiary planning
• probate
• wills
• joint ownership

US citizens and non-US citizens can have very different US estate-tax positions.

The portfolio should therefore also be considered within the wider estate plan.

32. The answer may change if you later leave Ireland

Your long-term destination matters.

If you expect to remain in Ireland permanently, the Irish tax framework deserves substantial weight.

If Ireland is a three-year assignment before returning to America, flexibility may be more valuable.

Do not restructure a lifetime portfolio around a temporary country move unless there is a clear reason to do so.

Investment planning for Americans in Ireland can involve:

• US federal tax
• Irish Income Tax
• USC
• PRSI on relevant income
• Irish Capital Gains Tax
• foreign tax credits
• treaty relief
• residence
• ordinary residence
• domicile
• remittance-basis rules
• Irish investment-fund taxation
• offshore fund rules
• deemed disposal
• PFIC rules
• Form 8621
• FBAR
• FATCA
• brokerage restrictions
• estate planning
• currency

The Irish general CGT rate is currently 33% for most gains, but certain investment funds and products fall under different tax regimes.

From 1 January 2026, the individual rate applicable to relevant Irish investment funds and equivalent qualifying offshore funds is 38%.

Investment classification is therefore essential.

US taxpayers should also review foreign mutual funds and ETFs for potential PFIC treatment before investing.

US tax advice should be obtained from a suitably qualified US tax adviser, CPA or attorney where required.

Irish tax and legal advice should be obtained from appropriately qualified Irish professionals.

Do not sell, transfer or restructure a substantial investment portfolio solely because you are changing country.

Investing involves risk. Investments can fall as well as rise, and you may get back less than you invest.

Tax rules, fund classifications, treaties and provider policies can change.
