Fund Mergers, Splits and Spin-Offs: PFIC Events That Don’t Look Like Sales

Key takeaways

• Section 1291 taxes what happens to your shares. A fund merger, a reverse split or cash for a fractional share all count, even though you sold nothing.
• Section 1291(f) lets regulations force gain on a PFIC transfer that would otherwise be tax-free. The only regulations under it are proposed.
• In the ordinary case a split spreads your basis over the new share count and carries your holding period. A qualifying merger carries both, lot by lot.
• Cash in lieu of a fractional share is treated as a redemption of the fraction. A gain on it is a section 1291 disposition and takes the fund outside the $25,000 Form 8621 exception that year.
• After a merger, the Form 8621 instructions require the new reference ID to be correlated with the old one in its first year.
• The PFIC Calculator & Form 8621 Generator handles splits, mergers, spin-offs, cash in lieu and ticker changes, and links old and new reference IDs after a merger.

You got this far. You know the fund is a PFIC, you know the 125% test, and you track your purchases block by block.

Then the fund company sends a notice. Your fund is merging into a sister fund, or ten shares are becoming one, or a few dollars arrive as cash in lieu of a fractional share. You sold nothing, so the spreadsheet stays as it is.

Here is what most calculations miss. Section 1291 doesn’t ask whether you meant to sell. It asks what happened to your shares.

Why does a corporate action matter for a PFIC?

Section 1291 taxes excess distributions and dispositions, and the Form 8621 instructions treat stock of a section 1291 fund as disposed of if it is sold, transferred or pledged. So a corporate action is a tax-free exchange, a disposition, a distribution or nothing at all. Which one it is decides your Part V this year, and the basis and holding period behind every later gain.

The rule over all of them: section 1291(f)

Section 1291(f) says that, to the extent provided in regulations, when PFIC stock is transferred without full recognition of gain, the excess of its value over its basis is recognized as gain “notwithstanding any provision of law”. It is a switch that can turn off the tax-free treatment of a reorganization.

Treasury’s rules under it exist only as proposed regulations, Prop. Reg. §1.1291-6, never finalized. Described broadly, they separate an exchange that leaves you holding stock of another PFIC, which the section 1291 regime can follow, from one that doesn’t. I keep this general on purpose. Section 1291(f) works only “to the extent provided in regulations”, and how far proposed rules can carry it is an open question. I work out every PFIC reorganization on its facts.

What does a merger do to your shares?

When a merger qualifies as a reorganization under section 368(a)(1), section 354(a) gives you no gain or loss, section 358(a) carries your basis into the new shares and section 1223(1) carries your holding period. Treas. Reg. §1.358-2(a)(2) makes basis follow the shares: as far as possible, each new share traces to old shares bought on the same date at the same price. That’s lot by lot.

Section 1291 takes its holding period from section 1223, so a later gain on the new shares is spread back over the years you held the old fund. If you already owned the surviving fund, you now hold lots of one fund with two different pasts. My guide to PFIC lot tracking explains why each one stays its own calculation.

Cash for all your shares is a disposition, and section 1291(a)(2) taxes the gain as an excess distribution. Cash alongside new shares brings recognized gain, up to the cash, under section 356(a). And a merger into a company that isn’t a PFIC leaves the deferral nowhere to follow you. That is the case section 1291(f) was written for, and the one I’d least want to guess at.

What do splits and reverse splits do?

A split is usually a distribution of stock on stock: section 305(a) keeps it out of income, section 307(a) spreads your basis across the old and new shares, and section 1223(4) carries the holding period. A reverse split is usually an exchange, tax-free as a recapitalization under section 368(a)(1)(E) or under section 1036, with basis and holding period carried over.

So in the ordinary case nothing is taxed and nothing resets. The trap is the per-share history. The 125% test runs share by share, and section 1291(b)(3)(B) requires proper adjustments for stock splits and stock dividends. Skip them and a spreadsheet can find an excess distribution that isn’t there, or miss one that is. My guide to the 125% test, block by block covers the test.

Did you consider the fractional share?

Reverse splits and mergers rarely divide evenly, so the fund pays cash for the fraction. Treas. Reg. §1.305-3(c) treats cash in lieu on a stock dividend as if the fraction were issued and then redeemed, with the cash taxed under section 302. The same approach is generally applied after a merger or reverse split, and for a fractional share it usually means exchange treatment: a sale of the fraction.

On a PFIC, a gain on that fraction is a disposition, taxed as an excess distribution and reported on Part V for the block of shares it came from. And under Treas. Reg. §1.1298-1(c)(2), the $25,000 exception doesn’t cover a fund in a year you recognize gain on it. A few dollars of cash in lieu can put a fund back on Form 8621. My guide to Form 8621 filing exceptions covers where each one stops.

Did you consider what a merger carries with it?

• Taint. Section 1298(b)(1) treats your shares as PFIC stock if the company “or any predecessor” was a PFIC during your holding period. My guide to tainted and clean PFIC lots follows that lot by lot.
• A predecessor. Section 1298(b)(2) lets a new company’s first year with income escape PFIC status only if no predecessor was a PFIC. The Code doesn’t define predecessor, but a fund that absorbed a PFIC is the obvious candidate. My guide to the PFIC start-up exception covers the other conditions.
• A new reference ID. A foreign fund often has no EIN, so Form 8621 identifies it by a reference ID you assign, the same one every year. After a merger or acquisition, the instructions require a new ID correlated with the old one, written as the new ID, a space, then the old ID, in the new ID’s first year.

Did you consider a spin-off?

Rare in a fund, less rare in a foreign holding company. Each of its three questions turns on facts in the company’s own documents, so I’ll raise them, not answer them.

• Basis and holding period. If it qualifies under section 355, section 358(b)(2) and (c) allocate your basis between the old and new shares, and section 1223(1)(B) carries the holding period. If it doesn’t, the new shares are a distribution of property under section 301, and on PFIC stock a distribution goes through the 125% test.
• Is the spun-off company a PFIC? It needs its own income test and asset test, year by year. The free PFIC Analyzer is a place to start.
• Does section 1291(f) reach it? That depends on the proposed regulations and the weight they carry.

Did you consider a new ticker, name or home?

A new ticker or name on the same shares of the same company isn’t a sale or other disposition. But some broker statements show the old line closing and a new one opening. A spreadsheet keyed on ticker sees two funds, starts a fresh holding period and loses every lot’s history, and a reference ID built from the ticker changes with it.

A move of the fund’s charter to another country is different. Section 368(a)(1)(F) treats “a mere change in identity, form, or place of organization of one corporation, however effected” as a reorganization, so it is an exchange in its own right, and the country of incorporation you report changes too. My guide to what makes a fund foreign for PFIC purposes covers why the charter decides that.

How the PFIC Calculator handles it

The PFIC Calculator & Form 8621 Generator handles splits and reverse splits, mergers and share exchanges with tacked holding periods and basis carried lot by lot, spin-offs, cash in lieu of fractional shares, and ticker or name changes. It also:

• keeps each fund’s reference ID the same every year, and links the old and new IDs after a merger;
• takes the country of incorporation from the charter and follows a fund that redomiciles, tax year by tax year;
• runs the 125% test per block, and files a separate Part V for each block of shares, as the Form 8621 instructions describe, with a loss kept on its own Part V;
• flags what it cannot know, such as shares transferred in with no basis or acquisition date, or a share balance that goes negative.

It won’t produce a figure when a rate or price is missing, and it computes section 1291 only, not QEF or mark-to-market. Whether a merger or spin-off qualifies as tax-free, or whether section 1291(f) reaches it, is a legal question about your facts. No calculator answers that for you.

When to have a CPA look

A corporate action is where one wrong entry quietly changes every later year. The calculator’s optional CPA review has a CPA check the calculator’s own workpapers before you file. It covers the workpapers the calculator produced, not a return or forms prepared somewhere else. The price is in the calculator’s pricing section.

Glossary

• Reorganization: a merger, recapitalization, change of place of organization or other transaction listed in section 368(a)(1). It can be tax-free for shareholders.
• Nonrecognition: a rule under which a gain or loss is realized but not taxed now. Basis and holding period usually carry into what you receive.
• Cash in lieu: cash paid instead of a fractional share after a split, merger or stock dividend.
• Reference ID number: the identifier you assign to a PFIC on Form 8621 when it has no EIN, used to track it from year to year.
• Predecessor: the word section 1298 uses to carry a company’s PFIC history into its successor. The Code doesn’t define it.
• Tacked holding period: a holding period that includes the time you held the property you gave up. See the PFIC excess distribution regime for why it matters.

Frequently asked questions

Is a fund merger a taxable event for PFIC shares?

It can be either. A merger that qualifies as a reorganization is generally tax-free under section 354, with basis and holding period carried over. But section 1291(f) lets regulations force gain on a PFIC transfer anyway, and the only regulations under it are proposed. Cash you receive is taxed, and gain on PFIC stock goes through section 1291.

Does a stock split change my PFIC holding period?

Not in the ordinary case. A split under section 305(a) carries the holding period into the new shares under section 1223(4), and section 307 spreads the basis over the new share count. The 125% test needs a proper adjustment for the split under section 1291(b)(3)(B).

Is cash in lieu of a fractional share a PFIC disposition?

Usually. The regulations treat it as if the fraction was issued and then redeemed, and section 302 usually treats that redemption as an exchange. A gain on it is taxed under section 1291, and it takes the fund outside the $25,000 Form 8621 exception for that year.

Do I need a new reference ID after a fund merger?

The Form 8621 instructions require a reference ID that correlates the previous ID with the new one after a merger or acquisition, entered as the new ID, a space and the old ID, in the first year the new ID is used. Otherwise the same ID must be used every year.

Is a ticker change a sale of my PFIC?

No. A new ticker or name on the same shares of the same company isn’t a sale or exchange. A change in where the fund is incorporated is different: it can be a reorganization under section 368(a)(1)(F).
