Offshore Investment

Katelynn Minott, CPA & CEO July 1st, 2026

Offshore investment means owning investment assets outside the United States, such as foreign mutual funds, ETFs, stocks, bonds, brokerage accounts, pensions, or investment accounts held through a foreign financial institution.

Why it matters for U.S. expats

U.S. expats must report investment income from worldwide sources. Offshore investments can also trigger extra reporting on FBAR, Form 8938, and Form 8621. Some foreign funds are treated as PFICs, which can create harsh U.S. tax treatment and complex annual filing requirements.

Common questions

1. Do U.S. expats pay U.S. tax on offshore investments?

Yes. U.S. citizens and green card holders report worldwide investment income, including foreign dividends, interest, capital gains, fund distributions, and certain pension or retirement account income.

2. What offshore investments cause the biggest U.S. tax problems?

Foreign mutual funds and foreign ETFs are often the biggest problem because they can be classified as PFICs. PFIC treatment can increase tax, add interest charges, and require Form 8621.

3. Are foreign ETFs safe for U.S. expats to buy?

Foreign ETFs can create PFIC reporting and tax issues for U.S. taxpayers. Many U.S. expats avoid them unless a cross-border tax adviser has reviewed the investment first.

4. Do offshore investments need to be reported on FBAR?

Foreign financial accounts holding investments can be reportable on FBAR if the combined value of foreign financial accounts exceeds $10,000 at any point during the year.

5. Do offshore investments need to be reported on Form 8938?

Yes, if the total value of specified foreign financial assets exceeds the Form 8938 threshold that applies to your filing status and residence.

6. Is foreign investment income eligible for the Foreign Tax Credit?

Foreign tax paid on foreign-source investment income can qualify for the Foreign Tax Credit if it is an income tax or a tax in place of an income tax. The credit is claimed separately from FBAR and FATCA reporting.

7. Can offshore investments affect state tax filing?

Yes. Investment income, brokerage records, and continued ties to a U.S. state can matter if the state still treats you as a resident or part-year resident.

8. Should U.S. expats use a U.S. or foreign brokerage account?

A U.S. brokerage account can reduce PFIC exposure, but some U.S. brokers restrict clients with foreign addresses. A foreign brokerage account can be easier locally but may increase U.S. reporting and PFIC risk.

9. What should expats check before investing abroad?

Check whether the investment is a PFIC, whether it sits in a foreign financial account, whether local tax will be withheld, whether treaty rules apply, and which U.S. forms will be required.
