Start My Foreign Pension 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 1040 and pension-distribution schedules
- Form 3520 / Form 3520-A (test the exceptions)
- Form 8621 for PFIC holdings inside the SIPP
- Form 8938
- FBAR (for holding accounts)
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 plan deed, provider, governing law, and investment-control facts
- The full holding list and each fund's legal issuer and domicile
- Contributions, employer funding, relief-at-source, and distributions by year
- Treaty residence, saving-clause facts, and prior U.S. filings
Documents to gather
Start with the governing document, then add the annual statements. Keep the original record together with any translation.
- SIPP plan deed, provider terms, and annual statement
- Complete holding list with legal issuers, domiciles, and identifiers
- Contribution, transfer, and distribution records by year
- Fund prospectuses, annual reports, NAV statements, and any AIS
- Prior U.S. returns and any Forms 3520, 3520-A, 8621, or 8938
Common record gaps and translation needs
- Provider statements that lack fund-level legal identifiers
- Missing annual information statements (AIS) needed for a QEF election
- Unclear basis and acquisition history for older holdings
Unresolved questions
These questions stay open until the governing documents, holdings, and filing-year facts are reviewed.
- Is the SIPP a foreign trust or grantor-trust arrangement for U.S. purposes, and do the exceptions apply?
- Which underlying holdings are PFIC stock, and is a Form 8621 filing trigger met?
- How were contributions and distributions reported under the treaty for each year?
