I became a US person after opening my Trading 212 account. Do the PFIC rules still apply?

Yes — PFIC status and the reporting that follows depend on your US-person status and the fund's domicile in each tax year, not on when or how the account was opened. Years from when you became a US person forward are in scope.

Are the ETFs in my Pie PFICs?

Yes — a Pie is a basket of individual instruments, and each UCITS ETF inside it is generally its own PFIC needing its own Form 8621; individual company shares inside the Pie are not. Check each slice's ISIN.

Does Trading 212 count for the FBAR?

Yes — it's a foreign financial account and counts toward the $10,000 aggregate at its maximum value during the year, cash and holdings alike.

Trading 212 & PFICs for US persons

Trading 212 doesn't onboard US persons — but accidental Americans and pre-status accounts exist, and the UCITS funds on it are PFICs.

Could this investment be a PFIC?

Two questions and, if you have it, the ticker or ISIN. The read is immediate, nothing you enter leaves this page, and it names what would settle the rest.

What is it?

Ticker or ISIN (optional)

Screened against the fund registry on this page. It is never sent anywhere.

A screen. Whether a fund is a PFIC turns on its own annual income and asset facts under §1297; the read above says how far your answers go and what would settle the rest.

Trading 212 made commission-free investing mainstream in the UK and Europe. For a US person its universe has the standard European problem: the funds are UCITS, and UCITS funds are generally PFICs.

Can a US person use Trading 212?

Trading 212's terms generally do not allow US persons to open accounts (confirm with Trading 212). The US taxpayers who hold one are typically accidental Americans, people who opened the account before acquiring US status, or dual citizens who didn't realise the restriction. US tax obligations apply to all of them all the same.

What's in the account

Holding at Trading 212	PFIC?	Typical filing
UCITS ETF (ISIN IE, LU…)	Likely	Form 8621 each year
Individual shares (incl. US stocks)	No	Report the account
'Pies' (auto-invest baskets)	Look through: each UCITS slice is a fund	Form 8621 per fund
Uninvested cash earning interest (QMMF sweep)	The sweep FUND is likely a PFIC	Check where the interest option parks cash

Two easy misses: a 'Pie' is just a basket — every UCITS ETF inside it is its own PFIC — and the interest-on-cash feature can park balances in a money-market fund, which is itself a non-US fund. Check the cash line of your statement.

FBAR and Form 8938

The account counts toward the $10,000 FBAR aggregate and the Form 8938 thresholds like any other foreign brokerage. Export the annual statement with maximum and year-end values.

From one fund to the whole case

What does your PFIC situation actually require?

Four questions — how many funds, for how long, whether Forms 8621 were ever filed, whether the returns are current — and a route into the preparation that fits, with what it costs. Nothing you answer leaves this page.

A routing read, not a determination. Whether a fund is a PFIC, whether an exception applies and what a prior year needs are established when the holdings are screened; the route above says where that happens and what it costs.

When a professional's judgment is needed. A person reads the facts before any package is sold when the fund screen cannot finish, when there are more than twenty-five likely PFICs, or when a late QEF or mark-to-market election is in question — whether a late election can still be made turns on the facts and is a professional's call.
