U.S. taxpayers must avoid purchasing foreign mutual funds, foreign ETFs, or foreign unit trusts through non-U.S. brokerage accounts. The IRS classifies these offshore pooled investments as passive foreign investment companys (PFICs) under IRC §1297. A foreign corporation is classified as a PFIC if it meets either of the following criteria:
75% or more of its gross income is passive income (dividends, interest, capital gains, royalties, or rents under the Foreign Personal Holding Company Income rules of IRC §954).
50% or more of its assets produce, or are held to produce, passive income.
If you do not make a timely election, the IRS subjects your PFIC investment to the punitive default rules of IRC §1291, “Interest on tax deferral”:
To escape the default excess distribution regime, U.S. taxpayers must file Form 8621 annually for every single PFIC owned and attempt to execute one of two elections:
The optimal election. You agree to include your pro-rata share of the PFIC’s actual ordinary earnings and net capital gains in your taxable income annually under IRC §1293, preserving preferential long-term capital gains tax rates on realized gains. However, the QEF election is structurally impossible for most retail investors: it legally requires the foreign fund manager to produce a highly detailed “PFIC Annual Information Statement” that complies with U.S. tax accounting rules, which foreign fund managers almost universally refuse to prepare.
Under ( IRC §1296) is available only for PFIC shares that are regularly traded on a registered national exchange or approved foreign exchange. You agree to mark the security to market on the last day of your tax year. Any paper gain is taxed immediately as ordinary income. Paper losses are deductible only to the extent of previously recognized MTM gains. While the MTM election eliminates the interest surcharge, it forces you to pay annual ordinary income taxes on unrealized paper gains.
The immense accounting fees and compliance costs of filing Form 8621, combined with the risk of confiscatory interest penalties, make foreign mutual funds entirely unsuitable for U.S. citizens and tax residents. All offshore capital must be held in U.S-domiciled vehicles or direct individual foreign stocks.
