Recommended next step
This product is mapped to the pfic consultation. The consultation organizes the facts and records before any preparation scope is written.
Start My IntakePossible U.S. reporting channels
These are screening questions, not conclusions. Whether a form applies depends on your specific facts and the current instructions for the filing year.
- Form 8621 for foreign pooled investments
- Form 8938
- FBAR (for the holding account)
- Form 1040 and investment-income schedules
Facts that can change the U.S. analysis
These facts matter more than the product name. Identify each one for the relevant year and preserve the document that supports it.
- The complete annual statement and holding list, including legal issuers and domiciles
- Whether any holding is a foreign mutual fund, ETF, or unit trust
- Cash versus individual foreign shares versus pooled funds
- Distributions, sales, transfers, and year-end values in original currency
Documents to gather
Start with the governing document, then add the annual statements. Keep the original record together with any translation.
- ISA provider terms and complete annual statement
- Holding-level list with legal issuers, domiciles, and identifiers
- Fund prospectuses, annual reports, NAV statements, and any AIS
- Transaction history, cost basis, distributions, and year-end values
- Prior U.S. returns and any Forms 8621, 8938, or FBARs
Common record gaps and translation needs
- Provider summaries that hide fund-level legal identifiers
- Missing AIS for a QEF election decision
- Unclear basis or acquisition dates for older holdings
Unresolved questions
These questions stay open until the governing documents, holdings, and filing-year facts are reviewed.
- Which holdings are PFIC stock, and is a Form 8621 filing trigger met for the year?
- Do FBAR and Form 8938 apply to the account and its maximum value?
- Was a QEF or mark-to-market election made, and is the supporting information complete?
