PFICs Inside Foreign Pensions: The Hidden Tax Trap for Expat Retirees

Many expat retirees believe their foreign pension is tax-protected because their host country does not tax pension growth. What they do not realize is that the IRS may view their pension as a foreign trust — and the funds inside that trust as PFICs.

The Double Layer Problem

Foreign pensions create a double layer of US tax complexity:

Layer 1: Is the pension a foreign trust?

• If yes → Form 3520 and 3520-A may be required.

Layer 2: Does the pension hold PFICs?

• If yes → Form 8621 may be required for each PFIC.

Result: A single foreign pension with 5 foreign mutual funds could require:

• 1 Form 3520
• 1 Form 3520-A
• 5 Forms 8621
• Plus your regular Form 1040

UK SIPPs and PFICs

UK SIPPs often hold UK-domiciled funds because the SIPP provider's default investment menu consists of local funds.

Common PFICs inside SIPPs:

• Vanguard UK-listed ETFs
• iShares European ETFs
• UK unit trusts and OEICs
• Global equity funds domiciled in Ireland or Luxembourg

Strategy:

• Hold direct UK stocks inside your SIPP instead of funds.
• UK blue-chip stocks (FTSE 100 companies) are operating companies, not PFICs.
• If your SIPP provider restricts you to funds, contact them to ask about direct stock dealing options.

Australian Superannuation and PFICs

Australian super funds (especially SMSFs) often invest in:

• Australian-domiciled ETFs (Vanguard Australia, iShares Australia)
• Managed funds from Australian providers
• Listed investment companies (LICs)

Many of these are PFICs for US taxpayers.

Strategy:

• If you have an SMSF, hold direct Australian stocks or international stocks through a US broker.
• If you are in an industry super fund, your investment choices are limited. Some industry funds offer "direct investment" options that allow you to pick individual stocks.
• Consider whether the US-Australia treaty provides any protection (limited guidance exists).

Canadian RRSPs and PFICs

The US-Canada treaty provides strong deferral for RRSPs, but it does not clearly eliminate PFIC reporting.

Common PFICs inside RRSPs:

• Canadian mutual funds
• Canadian ETFs
• US-listed ETFs are fine, but Canadian-domiciled ones are PFICs

Strategy:

• Hold US-listed ETFs inside your RRSP (e.g., VTI, VXUS, BND).
• Hold individual Canadian stocks rather than Canadian funds.
• Avoid TFSAs entirely — they are not treaty-protected and are foreign trusts.

The Compliance Cost

If your foreign pension holds multiple PFICs, the annual compliance cost can be significant:

• Professional fees: $500–$2,000 per Form 8621.
• Trust reporting: $1,000–$3,000 per Form 3520/3520-A.
• Total annual cost: $5,000–$15,000+ for a complex pension.

For some expats, the compliance cost exceeds the tax benefit of the foreign pension. In these cases, it may be worth:

• Moving pension assets to a US plan (if rollover is permitted).
• Holding only direct stocks and US-listed funds.
• Accepting the host-country tax treatment and filing US returns without the pension wrapper.
