Interactive Brokers, Switzerland and PFIC reporting
Check each fund and the account maintaining it. A broker name, ticker or ISIN prefix does not establish all of your US reporting obligations.

Direct answer
Does using Interactive Brokers avoid PFIC reporting?
No. The broker does not determine whether a holding is a PFIC. A US-organized fund cannot be a PFIC; a foreign corporation must be assessed under the PFIC income and asset tests, including any applicable exceptions and holding history.
Many conventional non-US pooled funds need PFIC analysis. An account's location is a separate FBAR and Form 8938 question. Confirm your own IBKR contracting entity, maintaining branch, product access and reporting documents directly rather than assuming that every Swiss customer has the same setup.

What changes the answer
- The legal vehicle, income and assets of the holding.
- Direct or indirect ownership, prior PFIC years and evidence for any election.
- The applicable Form 8621 filing triggers and exceptions.

Check it for your own holding
Could this investment be a PFIC?
Two questions and, if you have it, the ticker or ISIN. The read is immediate, nothing you enter leaves this page, and it names what would settle the rest.

A screen. Whether a fund is a PFIC turns on its own annual income and asset facts under §1297; the read above says how far your answers go and what would settle the rest.
Start with the holdings, not the broker
A foreign corporation may be a PFIC because of its income or assets. Conventional non-US pooled funds commonly need this analysis, including funds held through IBKR. A familiar index, exchange or trading currency does not establish the legal vehicle or settle the annual tests. Use the fund documents and the official Form 8621 instructions.
Confirm the account serving you
Use your account agreement and statements to identify the contracting institution and the branch maintaining the account. Ask IBKR to confirm current investment access and available tax reports for your own account. A US parent company or a US tax statement does not by itself settle foreign-account reporting.
Build the filing inventory before choosing an output
- List each fund and every relevant holding year.
- Recover acquisition dates, basis, sales, distributions and any election evidence.
- Screen potential PFICs, then check the filing triggers and exceptions in the official instructions.
- Use supported calculations only where the records and method fit; route uncertain elections, indirect holdings and missing history for professional review.
The PFIC cost calculator estimates preparation scope; the Form 8621 calculator models supported §1291 inputs. Neither selects an election or replaces professional advice. The software scope page explains worksheets, supported years, prices and who files.
Reading the IBKR Activity Statement for Form 8621
IBKR's Activity Statement is a single CSV with many sections, and each Form 8621 input lives in a different one:
- Trades — dated buys and sells per symbol: the lot history §1291 allocates a gain over.
- Dividends and Withholding Tax — dated distributions and the tax taken from them. The first feeds the 125% excess-distribution test; the second feeds the foreign tax credit.
- Open Positions — year-end quantity and value, the starting point for a mark-to-market computation and for Form 8938.
- Financial Instrument Information — each symbol's ISIN, which tells a UCITS ETF (an IE or LU ISIN, generally a PFIC) apart from a US-listed ETF (a US ISIN, not a PFIC).
The portfolio analyzer reads the multi-section format directly and separates the PFIC lines from the rest, so you can see the count of Forms 8621 before deciding how to produce them.
Identify the holdings that need a closer look
The free Swiss PFIC checker screens indicators and leaves uncertain classifications open. No account numbers or tax documents are needed for the initial screen.
From one fund to the whole case
What does your PFIC situation actually require?
Four questions — how many funds, for how long, whether Forms 8621 were ever filed, whether the returns are current — and a route into the preparation that fits, with what it costs. Nothing you answer leaves this page.

A routing read, not a determination. Whether a fund is a PFIC, whether an exception applies and what a prior year needs are established when the holdings are screened; the route above says where that happens and what it costs.
