What Is Form 8621?

The Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund is an IRS filing reporting PFIC holdings and elections.

Also known as: IRS Form 8621, PFIC Information Return.

How Form 8621 works

Form 8621 applies when a US person holds, directly or indirectly, shares in a foreign corporation meeting the PFIC income test of seventy-five percent passive income or the asset test of fifty percent passive assets, which commonly captures non-US mutual funds and ETFs. The filing is triggered by excess distributions, gains on disposal, a QEF or mark-to-market election, or the annual reporting duty under section 1298(f). Without an election, excess distribution rules spread gains over the holding period with an interest charge. Holdings worth 25,000 dollars or less at year end, or 50,000 dollars on a joint return, are generally excepted from part of the form, subject to conditions.

Form 8621 vs Form 5471

Unlike Form 5471, which concerns officers and shareholders meeting ownership or control criteria in a foreign corporation, Form 8621 applies to any US shareholder of a PFIC, even with a very small holding.

Example

Illustrative example: A US citizen living in Country A invests savings in a Country A index fund through a local broker. The fund is a foreign corporation earning mainly passive income, so the investor generally treats it as a PFIC and attaches Form 8621 to the US return where reporting is triggered.

Common misconception

Myth: A local pension-style or retail fund abroad is reported only on the FBAR.

Reality: Form 8621 can be required in addition to the FBAR and Form 8938, because PFIC reporting follows the fund's income and asset profile rather than the account in which shares sit.

Frequently asked questions

Who must file Form 8621?

Form 8621 is filed by a US person that is a direct or indirect PFIC shareholder when receiving certain distributions, realising gains, making QEF or mark-to-market elections, or meeting the annual reporting requirement under section 1298(f).

Do foreign ETFs require Form 8621?

Non-US ETFs and mutual funds organised as foreign corporations often meet the PFIC income or asset test, so US holders generally assess Form 8621 reporting fund by fund.
