PFIC portfolio analyzer

The scanner for a whole portfolio rather than one fund: say where it is held, drop in a positions or transactions export or add each fund by name, and get every holding screened by the same engine a paid return uses — likely PFICs, the ones that need review, the §1291 tax on anything sold this year, and the FBAR, Form 8938 and catch-up questions the account raises. No signup, nothing saved. For a single fund, the PFIC checker is faster; for one known sale, use the Form 8621 calculator.

1 · Where are your investments held?

Optional, but it is what turns a list of funds into a filing picture: the wrapper decides the trust and treaty questions, the balance band decides the FBAR, and the filing history decides the route back.

Wealthsimple

Wealthsimple's managed portfolios are built from ETFs, and the Canadian-listed ones are non-US pooled vehicles — generally PFICs. Self-directed accounts can hold US-listed ETFs, which are not.

A positions export (Schwab, Fidelity, Vanguard, Swissquote, DEGIRO, Questrade, Wealthsimple…), a transactions export, or an Interactive Brokers activity statement — as CSV. The file is read in this browser tab and never uploaded. XLSX and PDF are not read yet: export the same table as CSV.

What this tool answers

One question, answered properly.

It answers

Which of several holdings are PFICs, the §1291 tax on any you sold this year computed by the same engine a paid return uses, and the IRS forms that combination triggers.

It does not answer

Anything about holdings you do not enter, and it does not file. Classification is screening on the facts you give it, not a determination about the fund.

The rest of the PFIC cluster

Each of these answers a different question.
