For PFIC planning, C-suite expats, everything comes down to where the money sits. Non-US pooled funds — UK OEICs, unit trusts, investment trusts, and ISA funds — are treated as passive foreign investment companies by the IRS. Executives escape the trap by holding US-domiciled funds, direct securities, and treaty-protected pensions, and by filing Form 8621 correctly each year.
The label “passive foreign investment company” traces back to Internal Revenue Code section 1297, which sets out the two tests that apply to a fund. A non-US corporation is a PFIC if either 75% of its gross income is passive, or 50% of its assets produce passive income.
Almost every pooled UK investment vehicle clears that bar without effort. A UK OEIC, a unit trust, an investment trust, a money-market fund, and the London- or Dublin-listed ETFs that a private bank buys on your behalf are all corporations that hold shares and bonds and pass through dividends and interest. To Washington, they are textbook PFICs.
This catches senior executives more often than any other group, and rarely through their own decision. A newly relocated chief financial officer signs a discretionary mandate with a UK wealth manager, and the default portfolio is built from OEICs and Irish-domiciled ETFs. Bonus cash gets parked in a money-market fund.
The workplace share plan reinvests dividends into a pooled vehicle. None of it looks like an offshore scheme, yet each line is a separate PFIC that the executive must now report to the IRS.
The reporting mechanism is Form 8621, filed per fund, per year. Hold fourteen pooled funds,s and you file fourteen forms. The IRS instructions for Form 8621 run to dozens of pages precisely because the calculations behind each election are so involved. For business operators, the compliance cost alone is a compelling reason to restructure.
The instinct of most executives is to leave investments to advisers and deal with taxes in April. With PFICs, that instinct is expensive because the punishing default regime applies automatically the moment you own the fund — not the moment you sell it.
The three possible treatments are set out below, and the difference between them is measured in real money.
Under the default rule in section 1291, any “excess distribution” or gain on sale is thrown back across your entire holding period, taxed at the highest ordinary rate for each year, and then charged compound interest as though the tax had been due all along. Long-term capital-gain rates do not apply.
A five-figure gain on a fund held through a relocation can generate a tax-and-interest bill that swallows most of the profit. Sound PFIC planning for C-suite expats always starts by avoiding Section 1291 before a distribution or sale ever triggers it.

Regime |
How does it tax you |
Practical reality for executives |
|---|---|---|
|
§1291 excess distribution (default) |
Large dividends and gains are subject to compound interest in addition to top ordinary rates for each year they are retained. |
The worst outcome applies automatically unless you elect out in time |
|
QEF — section 1295 |
Annual pass-through of the fund’s ordinary earnings and capital gains, taxed as they arise |
Needs a PFIC Annual Information Statement, which almost no UK fund produces |
|
Mark-to-market — section 1296 |
Annual tax on unrealized gains as ordinary income; losses deductible up to prior gains |
Only for shares regularly traded on a qualified exchange; workable but at the ordinary rate. |
The cleanest result is typically the QEF election, but this is contingent upon the fund providing you with a compliant PFIC Annual Information Statement, which UK managers never do. That leaves the mark-to-market election under section 1296 as the realistic fallback for a listed fund. In our guide on QEF versus mark-to-market elections, we thoroughly evaluate the two options, and the decision can significantly affect an executive’s after-tax return. The trap is that both elections work best when made in the first year of ownership; leave it, and you inherit the section 1291 history you were trying to avoid.
Senior UK-based executives are routinely told the ISA is the sensible tax-free home for their savings. For an American, that advice is wrong twice over. The UK ISA shelters nothing from the IRS, because the US-UK treaty contains no article extending ISA status to US persons — every dividend, interest payment and gain inside the wrapper is fully taxable on the US return.
Worse, a stocks-and-shares ISA is usually filled with the exact pooled funds that count as PFICs, so the executive gets the full section 1291 treatment inside a wrapper they believed was tax-free. We unpack this in our note on the ISA tax trap for US persons, and it is the single most common mistake we correct for incoming C-suite clients.
The escape route is structural, not clever. It rests on moving investment capital out of non-US pooled funds and into holdings that the IRS treats as normal. In practice, PFIC planning for C-suite expats follows a short, repeatable pattern that a good adviser can implement within one or two tax years.
First, hold US-domiciled funds and ETFs inside a US brokerage account. A fund registered in the United States is not a PFIC, so it is taxed like any other US investment, with normal capital-gain treatment and no Form 8621. Our overview of US-domiciled funds for expats explains how executives can maintain a diversified, index-based portfolio without ever touching a PFIC.
Second, for wealth you want held in the UK, hold individual shares and bonds directly rather than in pooled vehicles — a share in a single company is not a PFIC. Third, avoid ISAs and OEICs as investment homes, and where existing elections are possible, make the QEF or mark-to-market election in year one.
Pensions are the reassuring exception. A UK workplace pension or SIPP generally receives protection under the pension articles of the US-UK income tax treaty, so the underlying funds are shielded from PFIC treatment while inside the plan. That is a deliberate treaty outcome, explained further in the IRS material on tax treaties. The distinction that trips executives up is simple: a real pension is protected; an ISA is not. Careful PFIC planning for C-suite expats leans hard on treaty-protected pensions and leaves taxable investing to clean, US-friendly structures.

Two situations catch the C-suite specifically. The first is relocation. An executive who moves to the United States, or an American posted to London, usually arrives with a pile of UK fund holdings already within the PFIC regime. The right move is to clean up before the move where the timing works — realizing and repositioning while still outside the harshest exposure — or immediately after, with elections made in the first US filing year.
Leaving legacy OEICs untouched turns a manageable position into years of Section 1291 interest.
The second trap is deferred compensation and share plans. Bonus cash awaiting investment, dividend reinvestment within an employer share plan, and vested equity swept into a default pooled fund all silently create PFICs.
Executives should check the default reinvestment setting on every employer plan and redirect it, and manage bonus cash so it never lands in a money-market OEIC. The interaction with equity awards is its own subject; we cover it in our guide to the US tax treatment of RSUs and stock options for expats, and the mechanics of the annual filing itself, including Form 8621, are explained. Thoughtful PFIC planning: C-suite expats treat these defaults as the first thing to switch off, not the last.
Deferred compensation adds a further wrinkle for the C-suite. Long-term incentive plans and non-qualified deferral arrangements often allow the executive to nominate where deferred sums are notionally invested, and the menu is frequently drawn from the very pooled funds that count as PFICs. Because these balances can run to seven figures and sit untouched for years, an unnoticed default here compounds quietly into one of the largest exposures on the whole return. Reviewing the deferral menu at the point of election — not at retirement — is where the real saving is made, and it costs nothing but attention.
Delphine Aretz, a dual US-UK citizen, was promoted to Chief Operating Officer of a London media group and inherited a GBP 900,000 portfolio her previous private bank had built entirely from UK OEICs and Irish ETFs — plus a maxed stocks-and-shares ISA she believed was tax-free. She had filed no Form 8621 in three years.
We mapped every line: eleven separate PFICs, each generating excess-distribution exposure under section 1291, and an ISA offering no US shelter at all. Over two tax years, we unwound the pooled funds, rebuilt the taxable core in US-domiciled ETFs held in a US brokerage, moved her long-term UK equity exposure into directly held shares, retained her treaty-protected SIPP, and redirected her employer share plan away from default fund reinvestment.
Where a listed holding had to be sold across a year boundary, we used a mark-to-market election to cap the damage. Delphine’s annual filing dropped from 11 Forms 8621 to 2, and her projected tax on the portfolio’s next disposal fell by roughly 40% relative to the section 1291 default.

If they are pooled vehicles — OEICs, unit trusts, investment trusts, money-market funds, or UK and Irish ETFs — then yes, almost certainly. Each pool invests money in a non-US corporation whose income and assets are passive, which is exactly what the passive foreign investment company definition captures. Directly held individual shares and bonds are not PFICs.
No. The US-UK treaty has no article recognizing ISA tax-free status, so every dividend, interest payment, and gain within the wrapper is taxable on your US return. Because most stocks-and-shares ISAs hold pooled funds, the holdings are also PFICs. The ISA gives an American no US shelter and often adds PFIC exposure on top.
It rests on three moves: holding your taxable portfolio in US-domiciled funds within a US brokerage, directly holding individual shares rather than pooled funds for UK exposure, and keeping investment capital out of ISAs and OEICs. Treaty-protected pensions stay as they are. Done early, this keeps you entirely out of the Section 1291 regime.
It taxes gains and large distributions at the top ordinary income rate for each year you held the fund, then adds compound interest as if the tax had been overdue throughout that period. It deliberately removes any benefit of long-term capital-gain rates or deferral, which is why escaping it before a sale or distribution matters so much.
Sometimes. A QEF election yields the best result but requires a compliant Annual Information Statement, which UK funds rarely provide. A mark-to-market election is available for shares regularly traded on a qualified exchange. Both work best in the first year of ownership; older holdings usually need to be unwound and repositioned instead.
