Usually yes. The test is not where the fund is marketed or what it is called, but whether a non-US corporation meets one of two statutory tests: a proportion of its income being passive, or a proportion of its assets producing passive income. A pooled fund holding shares, bonds and cash meets one or both almost by design. Canadian mutual funds, exchange traded funds and pooled segregated products therefore fall in, and so do many funds sold in the United Kingdom, India and the Gulf. The classification is made fund by fund and year by year, so a holding can be inside the regime for some of the years you held it and outside for others.

Why anyone asks
Terms in this area are shaped by citizenship-based taxation, which means they keep applying to someone who has not lived in the United States for decades. That is why a US-facing definition frequently reaches a person who assumed it could not.

Where the two countries disagree
Cross-border files go wrong quietly here: one country has a concept the other does not, so a position that is obviously right domestically has no counterpart abroad. The mismatch is the exposure, and it is found by mapping the term in both systems rather than in one.
Where you will actually see it
PFIC matters in the contexts below. Each of those pages says what it does there, and what it costs to handle.
What it means for your own file
If PFIC is in a notice you have received, bring the notice. The definition matters far less than what the sender is actually asking for. If that describes your position, the next step is a short call — not a form.
Where a concept appears in a treaty, the governing words are the ones in the treaty in force for your year, not the general description here. Protocols and multilateral positions change them more often than people expect.

Cross-border tax case studies
Identifying which portfolio positions were pooled foreign funds
A client held accounts with brokerages in two countries and had never been told that the classification question existed. The statements listed positions without distinguishing pooled vehicles from direct holdings. We went through the portfolio position by position, establishing the legal form of each issuer and whether it pooled investments, and reading prospectuses where the answer was not obvious. The engagement produced a holdings register that records, for each position, the classification reached and the document it was reached from. Subsequent years are prepared from that register rather than from the statements, which is what keeps the annual work proportionate.
Reconstructing acquisition dates for units bought decades earlier
The computations under the default regime turn on the length of the holding period, and the client's records began part way through. Original purchase confirmations had been lost in a house move. We obtained account histories from the fund's transfer agent, matched reinvested distributions to the units they created, and treated each reinvestment as its own acquisition with its own start date. The engagement produced a dated acquisition schedule for every tranche of units, which made the allocation calculations possible and gave the file a documented answer to the only question that drives them.
Computing the default regime where a manager published nothing
A client held two funds whose manager had no US investors and declined to produce annual information statements, which closed off the current-inclusion election for those holdings. Rather than press the manager, we established from the fund documents that the units were not redeemable in a way that opened the annual valuation route either. The default regime was therefore computed as it stood, with the allocation across the holding period and the interest element set out in a supporting schedule. The engagement produced a filed position, and a note recommending the manager question be asked before any similar purchase.
Working out inherited fund units and where the holding period starts
A client inherited units in a foreign pooled fund from a parent who had held them for many years, and assumed the inheritance reset everything. That question had to be answered before any computation could be done, because the holding period and the cost carried into the new hands drive the whole result. We assembled the deceased's acquisition records and the estate documents, took a documented position on the starting point, and prepared the return on that basis with the reasoning attached. The engagement produced a filed return and a written position the family can rely on for later years.
Simplifying a portfolio so later purchases raise no classification question
The annual cost of this client's file was driven by the number of pooled holdings rather than their value, and new purchases were being added each year without anyone asking the question. We set out, with the client's investment adviser, which kinds of holding raise the classification issue and which do not, so that the same market exposure could be obtained without multiplying the work. The engagement produced a short screening note the adviser now applies before buying, and a plan for the existing positions that deals with them in an order the client chose.
Putting several unreported years in order before choosing a route
A client came in intending to make a disclosure immediately, before anybody knew what was being disclosed. We did the classification and the computations first, for each holding and each year, which showed that the exposure was concentrated in one long-held fund and that the remaining positions were straightforward. Only then was the correction route selected, with the years taken oldest first. The engagement produced the filed years, a written chronology of what was held and when, and a supporting file that answers a later query from documents rather than from recollection.
Two Passports, Two Returns, One Income
Dual citizenship does not let you choose which country taxes you. The work is establishing residence, applying the treaty article that governs each income type, and preparing both returns from one set of figures so they agree line for line.

Industries & Client Types We Serve Worldwide
Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.
Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.

PFIC: further questions
The reporting obligation does not depend on making a gain, and the default regime is unkind about losses. A holding is reported for the year on a per-fund basis, and the questions asked include what you held, what it distributed and what you disposed of. A loss on a holding inside the default regime does not become an allowable loss you can set against other income the way an ordinary capital loss would, and it cannot be netted against a taxable amount arising on a different fund. So a portfolio that made nothing overall can still produce tax on one holding and nothing usable on another.
Because the default regime is not a tax on this year's gain. A distribution above a permitted amount, and any gain on sale, is thrown back across the period you held the units. Each earlier year's slice is taxed at the top ordinary rate in force for that year, with an interest charge running from when that year's tax would have fallen due. Nothing is treated as a capital gain, and the reliefs that normally soften investment income are unavailable. The effect compounds with time held, so a modest holding bought long ago can produce a liability out of all proportion to the amount received. Elections change this, but they have to be in place.
Work from the holdings, not from the account. A brokerage statement lists positions without saying which are corporations pooling investments and which are direct shares or bonds, so each position has to be identified: the legal form of the issuer, whether it pools, and whether it meets the income or asset test for that year. Some managers publish annual statements that settle the question and carry the figures an election needs; many publish nothing, and cannot be compelled to. Where nothing is published the position still has to be classified, from the prospectus and the financial statements. This identification step is the bulk of the work on most files.
Separately. The regime looks at each holding on its own, and the consequences follow the individual fund: its classification, the date you acquired it, what it has distributed, whether an election is available for it, and the character of what comes out. A portfolio of many small fund positions therefore generates many parallel computations rather than one, which is why the compliance cost is driven by the number of holdings rather than by their value. It is also why simplifying a portfolio, with your investment adviser, often does more for the annual cost of the file than any argument about the computations themselves.
It is a common position and it is fixable, but the order of work matters. First establish which holdings were inside the regime and for which years, because that decides the size of the problem. Then reconstruct the acquisition dates and cost, since the throwback calculation depends on the length of the holding period rather than on this year alone. Only then is it possible to say whether a correction covering earlier years is proportionate, or whether an election going forward plus a clean current filing is the sensible route. Choosing the disclosure route before the computations are done is how these files become more expensive than they need to be.
This is the classic hybrid mismatch. The United States generally treats a single-member LLC as transparent and taxes the member on the profit as it arises. Canada treats the LLC as a corporation and taxes the member on distributions. So the two countries tax different amounts in different years, and the foreign tax credit — which needs the same income taxed by both in the same year — often cannot bridge it. The treaty relief for hybrids is narrow. See why a Canadian should rarely own an LLC.
Three mechanisms, and which one you get depends on your residence country's law and the treaty. Exemption leaves the foreign income out of the residence-country base. Credit taxes it and then subtracts the foreign tax, capped at the residence-country tax on that income. Deduction merely reduces taxable income by the foreign tax, and is usually the weakest. Canada and the United States lead with credit; several treaties give exemption for specific income types. See claiming the credit.
