If you are a US citizen, a Green Card holder, or a British expat who has moved to the United States and become a US tax resident, and you hold a Quilter ISA, a Quilter Collective Investment Account (CIA), or a Quilter Collective Investment Bond (CIB), you are very likely holding investments that the Internal Revenue Service treats as Passive Foreign Investment Companies, or PFICs. This is not a minor technicality. It is one of the more punitive corners of the US tax code, and none of these three wrappers offers any protection from it.
The Quilter Collective Retirement Account, or CRA, which is the Quilter pension, is different: investments held within the pension wrapper are not subject to PFIC reporting during accumulation, because the wrapper itself is recognized under the US-UK Double Taxation Agreement. This guide covers all four Quilter wrappers, why the ISA, CIA, and CIB carry PFIC exposure and the CRA generally does not, and what the sensible next steps are. Your personal position should always be confirmed with a qualified US tax adviser.
Key takeaways
- The Quilter ISA, CIA, and CIB are UK domestic products with no recognition under US tax law. Their US treatment is driven by what sits inside them, and that is usually UK or European funds that the IRS treats as PFICs.
- A diversified ISA, CIA, or CIB holding fifteen or twenty underlying funds is not holding one PFIC. It is holding many, each assessed separately, each generally requiring its own Form 8621 every year.
- If you are a UK expat who has moved to the US, none of these holdings were PFICs when you bought them. They became PFICs on the day you became a US person, which is why the months before a move are worth more than any amount of tidying up afterwards.
- The default Section 1291 regime taxes gains at the highest marginal rate for prior years, with an interest charge, and it applies whether or not the fund has made money.
- The Quilter CRA, the pension, is the exception. Its holdings are not PFIC-reportable during accumulation, because the pension wrapper is recognized under the treaty.
- A Quilter CIB can, in some cases, also raise a foreign trust question, bringing Form 3520 and Form 3520-A into scope. This is fact-specific and should be assessed individually.
- Advising a US person on any of these four wrappers requires an adviser with individual SEC authorization. An FCA-only adviser is not equipped or authorized to do it properly.

Why US Tax Law Treats These UK Wrappers Differently
The Quilter ISA, CIA, and CIB are all UK domestic products, designed and regulated with UK residents in mind, and none of them has any recognition under US tax law. The UK tax-free status of the ISA means nothing to the IRS. The CIA is simply an ordinary taxable brokerage account from a US perspective. The UK life-fund taxation and chargeable event gain rules of the CIB have no US equivalent and are not recognized as tax-deferred insurance under US rules.
This matters because the US tax treatment of these three wrappers is driven entirely by what sits inside them, not by the wrapper. And what typically sits inside them, UK and European domiciled OEICs and unit trusts, is precisely the type of holding US tax law was written to catch. The CRA is the exception, addressed separately below.
If You Are a UK Expat Who Has Moved, or Is Moving, to the US
A large share of the people who reach this page are not American at all. They are British, they built a perfectly sensible portfolio of Quilter products while living and paying tax in the UK, and then a job, a spouse or a visa took them to the United States. Nothing about the investments changed. Everything about how they are taxed did.
Your Quilter holdings were not PFICs when you bought them
A UK domiciled fund inside a Quilter ISA is an ordinary UK investment when the person holding it is a UK resident. PFIC is not a property of the fund. It is a status that attaches once the holder becomes a US person, and it attaches to each underlying fund separately. The ISA wrapper, which does all the work in the UK, is invisible to the IRS, so the tax-free status you have relied on for years stops protecting you the moment you become a US tax resident. Most British expats find this out from a US accountant during their first filing season, by which time the year in question is closed and the choices that were available have narrowed.
The window before your US residency start date
Your exposure runs from your US residency start date, which depends on whether you hold a Green Card or meet the substantial presence test, and which certain elections can move. The practical consequence is simple even though the mechanics are not: decisions taken about UK holdings before that date sit outside the US net, and decisions taken after it do not. That makes the months before a move the single most valuable planning window a UK expat will get, and it is almost always the one that gets missed, because a relocation is dominated by visas, housing and schools rather than by fund domicile.
What can actually be done inside that window is US tax planning, and it belongs with a CPA or an Enrolled Agent rather than in an article. The point we would press is narrower: get the position reviewed before the date rather than after it. It is also worth knowing that your existing UK adviser will not be able to help you once you are US resident, because advising a US person on funds requires individual SEC authorization, as set out further down this page.
If you have already moved
If the date has passed, the window has closed and the question becomes how to manage the position rather than how to avoid it. Work through the rest of this guide, because the four wrappers do not behave the same way: the CRA pension is treated differently from the ISA, CIA and CIB, and a CIB can raise a separate foreign trust question. One warning before you act on your own. Selling the funds does not erase the reporting history and can crystallize the Section 1291 charge rather than end it, so establish the reporting position before making disposals. Our guide to whether a US resident can keep a UK ISA covers the wrapper question in more detail.
What Is a PFIC, and Why Are UK Funds Almost Always Caught?
Under Internal Revenue Code Section 1297, a foreign corporation is a PFIC if it meets either of two tests: 75 percent or more of its gross income is passive income, such as dividends, interest, and capital gains, or 50 percent or more of its assets, by average value, produce or are held to produce passive income. A typical UK-domiciled OEIC or unit trust, which exists to hold a portfolio of shares, bonds, or other securities and to distribute the resulting income and gains to investors, meets this test almost by definition.
This means a typical diversified Quilter ISA, CIA, or CIB, holding perhaps ten, twenty, or more underlying funds, is not holding one PFIC. It is holding many, and each one is assessed separately.
PFIC status does not depend on performance
A PFIC is defined by what the fund invests in and how it earns its income, not by whether it has made money for you. A fund that has fallen in value is still a PFIC if it meets the income or asset test. The tax and reporting consequences described below apply regardless of investment performance.
The Default PFIC Tax Regime Under Section 1291
Absent a valid and timely election, a PFIC holding is taxed under the default excess distribution regime in Section 1291. When you sell a PFIC at a gain, or receive a distribution larger than 125 percent of the average of the prior three years of distributions, the excess amount is treated as though it had accrued evenly over your entire holding period. The portion allocated to the current year is taxed as ordinary income. The portion allocated to earlier years is taxed at the highest marginal ordinary income tax rate in effect for each of those years, regardless of your actual tax bracket in those years, and an interest charge is added on top to reflect the deferral.
This produces materially worse outcomes than ordinary capital gains treatment in almost every case: no benefit from preferential long-term capital gains rates, no benefit from being in a lower tax bracket in earlier years, and an additional interest charge for the privilege.
Elections That Can Reduce the Impact, and Their Practical Limits
Two elections exist that can improve on the default regime, but both have real practical limits for UK retail funds.
- A Qualified Electing Fund, or QEF, election requires the fund itself to supply a PFIC Annual Information Statement each year, calculated under US tax principles. Very few UK or European retail funds provide this, so a QEF election is often simply unavailable.
- A mark-to-market election is available for PFIC stock that is regularly traded on a qualified exchange, and taxes the increase in value each year as ordinary income, with a corresponding ordinary loss allowed for declines, up to prior gains. Many underlying OEICs and unit trusts do not qualify as regularly traded on a qualified exchange in the way the election requires.
In practice, many US persons holding UK retail funds end up under the default Section 1291 regime for at least some of their holdings, simply because the more favorable elections are not available for the specific funds involved.
The Reporting Burden: Form 8621
Each PFIC generally requires its own Form 8621 to be filed with your US tax return each year you hold it, whether or not a distribution or disposal took place. A diversified Quilter ISA, CIA, or CIB holding fifteen or twenty underlying funds can mean fifteen or twenty separate forms every year. This is a compliance cost in its own right, quite apart from the tax, and it is one of the reasons US persons are generally advised to restructure these wrappers rather than simply hold them.
The CIB and an Additional Complication: Foreign Trust Classification
Beyond PFIC exposure in the underlying funds, some UK life insurance bond structures, including a Quilter CIB, can also raise the question of whether the arrangement constitutes a foreign trust for US tax purposes, depending on how the policy is structured and how much control and economic benefit the policyholder retains. Where that analysis applies, it brings its own separate and demanding reporting regime, potentially including Form 3520 for the US owner and Form 3520-A for the trust itself. Whether a specific bond is treated this way is fact-specific and should always be confirmed individually, not assumed either way.
Your Quilter Pension, the CRA: The PFIC Exception
If you hold a Quilter pension, it is almost certainly held in the Collective Retirement Account, or CRA, and it is treated differently from the other three wrappers. Investments held within the CRA, like those in any UK registered pension scheme, are not subject to PFIC reporting during accumulation, because the pension wrapper itself is recognized under the US-UK Double Taxation Agreement, with reporting relief under IRS regulations at Section 1298(f). This is a meaningful planning point: it means the PFIC problem described above is specific to the ISA, CIA, and CIB, and not to the pension.
This does not mean a CRA held by a US person is free of complexity. Drawdown should be structured with reference to the US-UK Double Taxation Agreement, including the correct application of the pension provisions and the treatment of the Pension Commencement Lump Sum, sometimes referred to as the 25 percent tax-free cash, under US income tax rules. The US treatment of that lump sum is genuinely unsettled: the absence of a clean treaty exemption can create a US tax liability if it is not planned for, so it should be modeled with your US tax adviser rather than assumed to be tax-free. Annual FBAR and Form 8938 reporting obligations also apply to the CRA as a foreign financial account, separately from the PFIC question.
FATCA, FBAR, and Form 8938
Separately from PFIC treatment, holding a Quilter CRA, ISA, CIA, or CIB as a US person also engages the standard foreign account reporting regime. The Foreign Account Tax Compliance Act, or FATCA, requires UK financial institutions to report US account holders to HMRC, which shares that information with the IRS. You are likely to have a Foreign Bank Account Report, or FBAR, filing obligation with FinCEN if your combined foreign accounts exceed 10,000 US dollars at any point in the year, and a Form 8938 filing obligation with your tax return if your specified foreign financial assets exceed the relevant threshold for your filing status and residence.
The Adviser Authorization Point for US Persons
Advising a US person on any of these four Quilter wrappers is not something an FCA-only adviser is equipped, or authorized, to do properly. It requires individual SEC authorization under the US Investment Advisers Act, alongside a working knowledge of PFIC rules, the US-UK Double Taxation Agreement, FATCA, FBAR, Form 8938, and, where relevant, foreign trust classification. Very few UK advisers hold this combination. Cameron James USA advisers hold individual SEC authorization, alongside our UK authorizations.
What Are the Alternatives?
For the CRA, the pension wrapper itself does not need to change to solve a PFIC problem, because there generally is not one. The priority is usually adviser authorization and drawdown planning, often through a transfer into an International SIPP structured with US-connected clients in mind. For the ISA, CIA, and CIB, there is no way to make the wrapper stop being a PFIC-holding structure while it continues to hold UK or European retail funds. The fix generally involves changing what is held, where it is held, or both, coordinated with your US tax adviser.
Holding as a US person, unreviewed, versus a US-aware restructured position
| Wrapper | Position as a US person, unreviewed | US-aware approach |
| CRA (pension) | PFIC-exempt within the wrapper, but the adviser is often not SEC-authorized, and the lump sum and drawdown are not planned for US tax. | Adviser holds SEC authorization; drawdown structured with reference to the treaty and the Pension Commencement Lump Sum. |
| ISA | PFIC exposure across most underlying funds; no US recognition of the wrapper. | Restructured toward non-PFIC or US-compliant holdings, coordinated with your US tax adviser. |
| CIA | PFIC exposure across most underlying funds; Form 8621 per fund likely. | Restructured fund selection, or a US-compliant brokerage arrangement. |
| CIB | PFIC exposure plus possible foreign trust considerations. | Reviewed for foreign trust risk; restructured where appropriate. |
How Cameron James USA Provides Holistic Cross-Border Planning
Cameron James USA works with US-connected individuals navigating the intersection of UK and US financial regulation, alongside British expats in the US and other non-UK residents. Our advisers hold individual SEC authorization and other relevant regulatory authorizations, and operate within an FCA-authorized firm. Our US-connected planning covers:
- CRA review and transfer into an International SIPP where appropriate, with drawdown structured around the US-UK Double Taxation Agreement and the Pension Commencement Lump Sum.
- Review of existing Quilter ISAs, CIAs, and CIBs for PFIC exposure, fund by fund, and for the CIB, an initial view on foreign trust classification risk.
- Restructuring options, including US-compliant fund selection, US brokerage platforms, and appropriately structured arrangements, coordinated with your US tax adviser.
- Coordination with your US tax adviser on Form 8621, FBAR, Form 8938, and, where relevant, Form 3520 and Form 3520-A.
- Estate and inheritance tax planning for US-connected clients with UK assets, including the interaction between UK and US succession and transfer tax rules.
- Financial planning across transition points, such as relocating between the UK and the US, or a change in family or employment circumstances.
There is also a cost point that matters here, because the PFIC question is one people put off precisely because they expect the review to be expensive. Cameron James USA does not charge an initial advice fee on US-connected investments or US pensions, so finding out where you stand on your Quilter holdings does not itself carry a fee. Ongoing advice, platform and fund charges still apply and are published in full.
What This Means for You
If you are a US citizen, a Green Card holder, or a US tax resident holding a Quilter CRA, ISA, CIA, or CIB, the starting assumption should be that the ISA, CIA, and CIB carry PFIC exposure in their underlying holdings, that the default US tax treatment is punitive, and that this does not improve by leaving the position unreviewed. The CRA is generally the exception, but it still needs SEC-authorized advice and proper drawdown planning.
The value of investments can fall as well as rise, and past performance is not a guide to future results. Tax rules are complex, differ significantly between the UK and the US, and change. Cameron James USA does not provide US tax advice directly; the sensible first step is a joint review with a cross-border adviser and your US tax adviser. Our fee schedule is published in full on our Our Cost page.

Frequently Asked Questions
Is my Quilter pension a PFIC?
Generally, no. Investments held within a UK registered pension scheme such as the CRA are not subject to PFIC reporting during accumulation, because the pension wrapper is recognized under the US-UK Double Taxation Agreement. This differs from the ISA, CIA, and CIB.
I am a British expat who moved to the US. Do these PFIC rules apply to me even though I am not a US citizen?
Yes. What matters is whether you are a US person for tax purposes, which includes Green Card holders and anyone who meets the substantial presence test, not only US citizens. If you are a US tax resident, the PFIC rules apply to your Quilter ISA, CIA, and CIB holdings in the same way.
I am moving to the US next year and hold a Quilter ISA. Should I do anything before I go?
Yes, and the timing matters more than the detail. The options open to you before your US residency start date are wider than the options open to you afterwards, so the review is worth doing while you are still UK resident rather than in your first US filing season. What you should actually do is a US tax question and needs a CPA or an Enrolled Agent, working alongside an adviser who holds individual SEC authorization and can act on the investments once you have moved.
Is my Quilter ISA, CIA, or CIB definitely a PFIC?
The wrapper itself is not a PFIC; the underlying funds usually are. Most UK and European domiciled OEICs and unit trusts held within these three wrappers meet the PFIC income or asset test, but this should be confirmed fund by fund.
Does the UK tax-free status of the ISA help with the US PFIC problem?
No. The ISA wrapper has no recognition under US tax law. The PFIC analysis applies to the underlying funds regardless of how they are taxed in the UK.
What is the difference between the QEF election and the mark-to-market election?
A QEF election requires the fund to provide US-specific annual reporting, which most UK retail funds do not offer. A mark-to-market election is only available for PFIC stock regularly traded on a qualified exchange. Where neither is available, the default Section 1291 regime applies.
Do I need to file Form 8621 for every fund in my Quilter CIA?
Generally, yes, one Form 8621 per PFIC per year, subject to certain de minimis exceptions. This should be confirmed with your US tax adviser based on your specific holdings and filing thresholds.
Is my Quilter CIB a foreign trust?
Not necessarily, but it can be, depending on the specific policy structure and the degree of control and benefit retained by the policyholder. This should be assessed individually rather than assumed either way.
What should I do about the Pension Commencement Lump Sum from my CRA?
The absence of a clean UK tax credit on this amount can create a US tax liability if it is not planned for, so timing and structuring should be reviewed with reference to the US-UK Double Taxation Agreement and confirmed with your US tax adviser before you draw it. Its US treatment is genuinely unsettled, so it should be modeled rather than assumed.
Should I encash my Quilter ISA, CIA, or CIB immediately?
Not automatically. Encashment itself can trigger a UK and, potentially, a US tax event, so the right course of action depends on your specific holdings, gains, and objectives. A proper review, coordinated with your US tax adviser, should come before any decision to encash.

“I meet a lot of US-connected clients, many of them British expats now living in the US, who have no idea their ISA, CIA, or CIB is full of PFICs, because nothing about the UK paperwork mentions it. Then, in the same conversation, they are relieved to learn that their CRA does not have the same problem, because the pension wrapper is actually recognized under the tax treaty.
That distinction matters. It is not a reason to leave the ISA, CIA, or CIB unreviewed, but it is a reason not to panic about the pension. If you are US-connected and hold any of these four, it is worth having the whole picture looked at properly, alongside your US tax adviser.”
