PFIC
A PFIC is a foreign pooled investment — most non-US mutual funds, ETFs, and many investment-style accounts. US owners face punitive tax and complex Form 8621 reporting, which is why non-US funds (including many held in ISAs) are problematic for Americans.

In more detail
The PFIC rules impose a harsh default tax regime (with interest charges) and onerous Form 8621 reporting on US owners of foreign pooled investments. Because most UK funds, investment trusts, and fund-based ISAs are PFICs, Americans in the UK are frequently caught — a UK-tax-efficient ISA can be a US tax problem. Elections (QEF or mark-to-market) can soften the treatment but require information UK funds rarely provide.
