Italian UCITS funds are nearly all PFICs under US rules. Default treatment can tax a 10-year gain at retroactive top rates with interest charges that exceed the gain itself.

You move to the US, intending to keep your Italian portfolio of mutual funds and ETFs. They've performed well; selling now means Italian capital-gains tax. So you keep them.
What you don't know: the moment you become a US tax resident, those funds are almost certainly PFICs (Passive Foreign Investment Companies) under §1297. The default tax treatment is among the most punitive in the US Internal Revenue Code.
A foreign corporation is a PFIC if either:
Italian mutual funds, SICAVs, ETFs and most UCITS structures meet both tests almost universally. Their entire purpose is passive investment.
The default rule punishes accumulated growth. When you sell the PFIC or receive an "excess distribution":
A 10-year hold with a 50% gain can trigger a tax bill that exceeds the gain itself.
You can opt out of §1291 with one of three elections — but each has barriers:
The cleanest economic outcome: annual inclusion of income, capital-gain treatment preserved. But it requires the PFIC to provide a "PFIC Annual Information Statement." Italian retail funds almost never produce this — there is no demand from Italian investors who don't pay US tax.
Annual gain or loss as ordinary income/loss based on year-end market value. Available only for PFICs traded on a "qualified" exchange. Many Borsa Italiana ETFs may qualify; most retail mutual funds don't.
MTM eliminates the §1291 interest charge but accelerates tax on unrealized gains.
The punitive default. Avoid where possible.
For most Italians, the cleanest approach is:
The lifetime tax saved versus default PFIC treatment usually exceeds the upfront Italian capital gain by 10x.
Most are domiciled in Ireland or Luxembourg (UCITS). They are still PFICs because the test is based on the foreign corporation's nature (passive investment), not the listing venue. The listing may make MTM available, but it does not exempt them.
Whatever election you choose, Form 8621 must be filed for every PFIC interest, every tax year. Failure to file leaves the year open to IRS assessment indefinitely.
