TurboTax can't file Form 8621 (PFIC) — here's the fix

You finished your return in TurboTax — but it never asked about your foreign funds, or it told you outright that it can't handle Form 8621. You're not doing anything wrong. Mainstream U.S. consumer tax software is built for U.S.-domiciled holdings, and the PFIC regime is exactly the part it leaves out.

Does TurboTax support Form 8621?

Short answer: no. Based on TurboTax's own support guidance and what expat filers consistently report, Form 8621 — the information return for passive foreign investment companies (PFICs) — is not part of the guided interview, and TurboTax does not support e-filing it. Separately, TurboTax does not file the FBAR either: that's a distinct filing made with FinCEN, not with your tax return.

Why this happens to Americans abroad

A PFIC is, in practice, most non-U.S. pooled funds — UCITS ETFs, Swiss and European funds, and the fund holdings inside a fund-based Pillar 3a. PFIC status turns on the fund's non-U.S. structure, not on what it invests in. TurboTax is designed around U.S. brokerage 1099s; it never asks the questions that would surface a foreign fund, so the 8621 obligation stays invisible until you find out the hard way.

You're likely affected if any of these apply:

• You hold a UCITS / EU / Swiss-domiciled ETF or fund (Ireland, Luxembourg, or Switzerland domicile).
• You invest through a non-U.S. broker (Swissquote, UBS, PostFinance) or the IBKR UK branch.
• You have a fund-based Pillar 3a (VIAC, finpension, Frankly) as a U.S. person.
• You received distributions from, or sold, a foreign fund during the year.

What Form 8621 actually involves

Without an election, a PFIC falls under the default §1291 "excess distribution" regime: gains and certain distributions are taxed as ordinary income at the highest rate, spread back across your holding period, plus an interest charge on the deferred tax. Two elections can change this — QEF (§1295) and mark-to-market (§1296) — but each has its own requirements, and each PFIC generally needs its own Form 8621.

There is a reporting exception worth checking: if the aggregate value of your PFIC stock is $25,000 or less ($50,000 or less married filing jointly) and you have no distributions or dispositions to report, Form 8621 filing may not be required for that year. (Verify against the current IRS Form 8621 instructions for your facts.)

What TurboTax skips vs what an expat with foreign funds actually needs

How to file Form 8621 without a $200-per-form CPA

You have three realistic options: hand-build the §1291 worksheet yourself (accurate but painful), pay a human firm — most charge $150–$300 per Form 8621, so multi-fund investors pay per form — or use self-serve software that detects your PFICs and drafts the forms for a flat fee. Atamatax's PFIC tier is $499 flat and includes up to 25 Forms 8621.
