Form 8621: QEF vs Mark-to-Market vs Section 1291

Three regimes can apply to the same passive foreign investment company, and which one you get depends on what you elect and when. Elect nothing and you fall into the default section 1291 excess distribution regime, which spreads gains and large distributions back across your whole holding period, taxes each prior year at the highest rate then in force, and adds an interest charge. The escapes are a QEF election under section 1295, which needs an annual statement the fund has no commercial reason to produce, and a mark-to-market election under section 1296, open only to "marketable stock". Both are normally made on a timely filed return for the first year of the holding period, and both are generally irrevocable without the Commissioner's consent.

This is the mechanics companion to our overview of PFIC tax rules for US investors abroad.

Key takeaways

• Doing nothing is a choice, usually the expensive one. Section 1291 denies capital gains rates and loss relief, and adds an interest charge computed under the section 6621 rates.
• QEF is the best regime and the least available. Whether you get the required statement is the fund's decision, not yours.
• Mark-to-market turns on a definition. "Marketable stock" means regularly traded on a qualified exchange, or a fund meeting all eight conditions in Regulations section 1.1296-2(d)(1).
• Timing is the whole game. Elect in the first year of the holding period for a clean start; elect later and the taint survives unless you purge it - and under section 1298(b)(1) stock stays PFIC stock even after the company stops qualifying.

The three regimes side by side

| | Section 1291 (no election) | QEF - section 1295 | Mark-to-market - section 1296 |

|---|---|---|---|

| Annual income | None until a distribution or disposition | Pro rata earnings and net capital gain, distributed or not | Year-end value over basis |

| Character | Ordinary; no capital gains rates | Ordinary plus long-term capital gain | Ordinary, per section 1296(c)(1)(A) |

| Rate | Highest rate under section 1 or 11 for each prior year | Your normal rates | Your ordinary rates |

| Interest charge | Yes - section 1291(c)(3) | No | No |

| Losses | Ignored | Normal rules | Capped at "unreversed inclusions" |

| UK fund availability | Always | Rare - needs the fund's help | Sometimes - needs "marketable stock" |

| Revocability | n/a | Consent only | Consent, or automatic termination |

Doing nothing: why section 1291 is punitive

Section 1291 does not tax you as you go. It waits, then bills you for the deferral you supposedly enjoyed.

Two events trigger it. An excess distribution is defined by section 1291(b) as the part of the year's distributions exceeding 125% of the average over the three preceding tax years, or the shorter part of your holding period; the total is zero in the year the holding period begins, so a first-year dividend cannot be one. On a disposition, the entire gain is an excess distribution, and a loss is not taken into account at all.

Part V is where the pain is. Per the Instructions for Form 8621, you divide the excess distribution by the days in your holding period, allocate it across them, and then:

• Amounts allocated to the current year and to pre-PFIC years are ordinary income now.
• Each prior PFIC year's amount is excluded from income but multiplied by the highest rate under section 1 or 11 for that year, and the results summed as additional tax.
• Creditable foreign taxes allocated to a PFIC year reduce that year's increase but not below zero, and unused amounts cannot be carried over.
• Interest runs on each year's increase from that year's return due date to the due date for the year of the distribution or disposition, "determined by using the rates and methods under section 6621".

So you lose capital gains rates, pay at the top statutory rate regardless of your bracket, and face a charge that grows with the holding. The investor who bought a UK fund fifteen years ago and forgot faces the largest bill.

Relief at the bottom end is narrow: an exception from completing Part I where aggregate PFIC stock is $25,000 or less on the last day of the year ($50,000 for joint filers), with a separate $5,000 threshold for certain indirect holdings and no excess distribution or section 1291 gain. That is an exception from one part of one form, not from filing or from the tax.

The QEF election: best regime, usually out of reach

A QEF election under section 1295 treats the fund much like a US mutual fund. Each year you include your pro rata share of ordinary earnings as ordinary income and of net capital gain as long-term capital gain, distributed or not, with basis adjusted for inclusions and distributions. No interest charge, no top-rate recomputation, and long-term gain keeps its character; Election B under section 1294 can defer tax on undistributed earnings.

Almost nobody holding a UK fund gets there, because of one document.

Regulations section 1.1295-1(g)(1) requires the PFIC to provide a signed PFIC Annual Information Statement for each of its tax years ending within your election year: the fund's tax year dates; your pro rata shares of ordinary earnings and net capital gain, or enough information to calculate them; distributions in cash and property; and either permission to inspect and copy the permanent books and records or a description of Commissioner-approved alternative documentation.

The regulation reads as a duty on the fund, but the consequence of non-performance falls on you. A UK OEIC has no US filing obligation, no US regulator to answer to, and often no interest in the few Americans on its register. If it declines, you cannot meet the annual election requirements and the election is unavailable in substance, even though the box sits there on the form. The alternative documentation route needs a private letter ruling and closing agreement, and is available only in rare circumstances.

So ask, in writing, before money moves: do you issue a statement to US shareholders, for which share classes and fiscal years, automatically or on request? Pro rata figures or raw data? Does it include the books-and-records undertaking, and are combined statements available for lower-tier PFICs? Some large non-US managers do produce these; a fund that has never heard of the document is telling you the answer. Check this per fund, per year.

Recordkeeping is part of the election: under Regulations section 1.1295-1(f) you must keep every Form 8621, attachment and annual statement for each year it is in effect, and failing to produce them on request can invalidate it - treated as though it was never made, dropping you into section 1291 for the whole period.

The mark-to-market election: it turns on "marketable stock"

A section 1296 election is the realistic alternative. Each year you include the excess of year-end fair market value over adjusted basis as ordinary income. Where basis exceeds value you get a deduction, but only up to your unreversed inclusions - prior inclusions less prior deductions for the same stock, under section 1296(d). Everything is ordinary, so capital gains treatment goes permanently; in exchange, so do the interest charge and the top-rate recomputation.

The gate is the definition. Section 1296(e) and Regulations section 1.1296-2 give two routes.

Route one: regularly traded on a qualified exchange

Stock is regularly traded for a calendar year if it trades, in other than de minimis quantities, on at least 15 days during each calendar quarter, with a relaxed test in an IPO year and an anti-abuse rule disregarding trades made principally to meet it.

A qualified exchange or other market is a national securities exchange registered with the SEC, the national market system under section 11A of the Securities Exchange Act of 1934, or a foreign exchange regulated by a governmental authority in its home country with enforced listing, disclosure and surveillance rules designed to prevent fraud and promote active trading.

This is the plausible route for UK investment trusts and London-listed ETFs. Whether a particular London Stock Exchange segment meets the test is a determination against those criteria, not something you can look up - the IRS publishes no definitive list of qualified foreign exchanges for this purpose. Confirm the exchange analysis for the specific listing and years.

Route two: the eight conditions for NAV funds

Open-ended UK funds are not exchange traded at all. Regulations section 1.1296-2(d)(1) gives them a separate route, for a foreign corporation offering for sale or having outstanding stock redeemable at net asset value, provided all of the following hold for your class throughout the calendar year:

• more than 100 shareholders in the class, ignoring shareholders related under section 267(b);
• readily available to the general public at NAV, minimum initial investment no more than $10,000;
• quotations published at least weekly in a widely available permanent medium not controlled by the issuer;
• annual audited financial statements, including a balance sheet and an income and expense statement, made public;
• regulated as an investment company by a foreign government body with broad inspection and enforcement authority;
• no senior securities authorised or outstanding, including debt beyond de minimis amounts;
• at least 90% of gross income passive under section 1297(a)(1); and
• at least 90% of assets, on average, producing or held to produce passive income.

A conventional FCA-authorised OEIC or unit trust may satisfy several. Others cannot be assumed: institutional and clean share classes often carry minimums above $10,000, publication in a medium the issuer does not control is not automatic, gearing raises the senior securities question, and the 90% tests are annual facts. Check each condition against the prospectus, accounts and published pricing for every year in issue - this is a per-fund, per-share-class, per-year analysis.

The election can also end without you doing anything: under Regulations section 1.1296-1(h)(3) it terminates automatically if the stock ceases to be marketable, putting the holder back under section 1291.

Timing, and what a late election costs

Both elections are due by the due date of the return, including extensions, for the first year to which they apply - Regulations section 1.1295-1(e) for QEF, Regulations section 1.1296-1(h)(1) for mark-to-market. A late section 1296 election is permitted only under the section 9100 relief provisions: discretionary, not a filing you can simply make.

For QEF, an election in the first year of the holding period produces what the instructions call a pedigreed QEF - the fund is treated as a QEF throughout and section 1291 never applies. Elect later and you have an unpedigreed QEF: the rules govern forward, but the earlier years remain section 1291 years, so a later disposition still drags the old period through the excess distribution machinery.

A genuinely retroactive QEF election is governed exclusively by Regulations section 1.1295-3, which displaces section 9100 relief and offers two routes:

1. Protective statement. Only if, as of the original election due date, you reasonably believed the corporation was not a PFIC, and filed a statement with that year's return setting out that belief and extending the limitations period for all PFIC-related taxes for every covered year. It had to be done at the time; it is not a repair.

2. Special consent. A ruling request to the Office of the Associate Chief Counsel (International), with a user fee, requiring reasonable reliance on a qualified tax professional who failed to identify the PFIC or advise on the election, no prejudice to the interests of the US government, and a request made before an IRS representative raises PFIC status on audit.

Purging elections, and once a PFIC always a PFIC

Where a PFIC becomes a QEF after the first year, section 1291(d)(2) allows a purging election: you recognise gain as if the stock were sold at fair market value on the first day of the QEF year. The gain is taxed as an excess distribution - you pay the section 1291 price once - but basis increases by it and a new holding period begins that day, giving a pedigreed QEF from then on. A parallel deemed dividend election on post-1986 earnings and profits applies to a controlled foreign corporation.

Election D (deemed sale with a QEF election) and Election E (deemed dividend) are due by the due date of the original return for the qualification year, or on an amended return within three years. Elections F to H, under Regulations sections 1.1297-3 and 1.1298-3, cover a corporation that has ceased to be a PFIC; once that window closes they move to Form 8621-A, which carries interest to the filing date.

Why bother? Because section 1298(b)(1) treats your stock as PFIC stock if, at any time during your holding period, the corporation or a predecessor was a PFIC that was not a qualified electing fund for you - whatever it is now. A fund that was passive for two years a decade ago still contaminates the whole period, subject to a narrow carve-out in section 1298(b)(3) for a corporation changing businesses. Purging is cheapest the year the fund stops being a PFIC.

How this lands on the UK side

ISAs. A stocks and shares ISA is a wrapper, not an entity. The US does not recognise it, so each underlying fund is its own PFIC with its own Form 8621 - the point we make at length in why the ISA tax wrapper doesn't cross the Atlantic. Worse, the UK tax-free status usually means no UK tax to credit against the US charge, and there is no exclusion to fall back on: the instructions exclude holdings through certain section 401(a), 403(b), 457(b), IRA and 529 arrangements, and an ISA is none of those.

OEICs and unit trusts. Open-ended, redeemable at NAV, not exchange traded - the Regulations section 1.1296-2(d) cases above, decided per share class per year. Accumulation units add a second trap: income is reinvested, so there is no cash in hand to pay a US charge computed on it.

Investment trusts and UCITS ETFs. Closed-ended London-listed companies and exchange-traded funds are the better candidates for route one, subject to the exchange and 15-day analysis. They remain PFICs; only the regime is in question. And UK reporting fund status does nothing for the US analysis.

Catching up several back years at once

Most PFIC problems surface in a disclosure rather than a filing. The Streamlined Foreign Offshore Procedures require delinquent or amended returns for the most recent three years for which the due date has passed, delinquent FBARs for the most recent six years, the non-residency requirement (for citizens and green card holders, no US abode and at least 330 full days outside the United States in one or more of those years), and a signed Form 14653. Our guide to Streamlined Foreign Offshore Procedure eligibility covers the gateway tests.

Holding periods run far longer than three years, and section 1291 allocates across the whole period regardless of how many returns you file - so a fifteen-year holding produces fifteen years of allocated amounts and interest inside a three-year submission. An election made on a Streamlined return is also made on a delinquent or amended return, not an original timely filed return for the first year of the holding period, which raises whether it can be effective at all for that year and whether purging is the better route. The IRS Streamlined pages address retroactive relief for certain treaty-based retirement plan deferral elections; they say nothing about PFIC elections. Confirm this on the specific facts.

Recordkeeping

• Acquisition date and cost for every lot, in original currency and translated - the holding period is the denominator in the whole section 1291 computation.
• Every distribution with its date, so the three-year average behind the 125% test can be built, each translated at the spot rate on its distribution date.
• Year-end values and unreversed inclusions for every mark-to-market year; every annual statement for each QEF year; a basis schedule, since all three regimes adjust basis differently; and the elections themselves, with the return and year each was made on.

Elections are fact-specific and generally irrevocable

This is general information about the US tax treatment of PFIC elections, not investment advice and not a substitute for advice on your facts. Every point above turns on the specific fund, share class, holding period and years in question. Both elections are one-way doors, revocable only with the Commissioner's consent, and a purging election crystallises real tax in the year it is made.

When to get help

If you hold UK funds and have never filed a Form 8621, the useful work is not choosing an election. It is establishing which elections were ever available to you, and in which years: pinning down the holding period, testing marketability against the regulation, modelling section 1291 as the baseline, then deciding whether an election, a purging election or simply paying the default charge leaves you better off.

We do that analysis as US-UK tax specialists, with every US filing reviewed and signed off by an IRS Enrolled Agent who is also ACCA-qualified on the UK side. If that is where you are, book a consultation.
