If you worked abroad — even for a few years — you may have a foreign pension or employer retirement plan quietly accumulating value. For Form 8938 purposes, these arrangements are among the most reportable and the most confusing assets you can hold. Here's why they cause so much trouble, and how to think about them.
The starting point: they're usually reportable
A foreign pension or deferred compensation plan is generally a specified foreign financial asset. That means your interest in the plan counts toward your reporting threshold and, if you're over it, must be reported on Form 8938. This surprises people who think of a pension as something they can't touch yet — but Form 8938 cares about the interest you hold, not whether you can withdraw it today.
Reporting the asset is separate from taxing the income
Two different questions get tangled here. One is disclosure: does this pension go on Form 8938? (Usually yes.) The other is taxation: is the growth inside the pension taxable to you now, and does a treaty defer it? Those are governed by different rules. You can have a pension that must be disclosed on Form 8938 even though a treaty defers U.S. tax on its internal growth.
Why valuation is the hard part
The single biggest practical headache is putting a number on the pension. Unlike a bank account with a monthly statement, many foreign pensions won't hand you a clean lump-sum value — especially defined-benefit plans that promise a future income stream rather than a current account balance.
The instructions provide fallback approaches for exactly this problem. Broadly:
- If you know the fair market value of your interest, use it.
- If you can't determine the fair market value but received distributions during the year, the value of your interest can be based on those distributions.
- If you can't determine the value and received nothing during the year, a value of $0 may be permissible for the maximum value — though you generally still report the account's existence.
We walk through the mechanics in more general terms in Valuing Foreign Assets for Form 8938.
Employer plans vs. personal accounts
The nature of the plan matters. A personal foreign retirement account that looks and behaves like a brokerage account is usually straightforward: it has a balance, and you report that. A workplace pension — particularly a defined-benefit scheme where your employer promises a future payout — is where valuation and characterization get genuinely difficult, because there may be no "account" balance attributable to you at all.
Treaties don't turn off Form 8938
A common and costly assumption is that a favorable tax treaty makes a foreign pension "invisible" to the IRS. It generally doesn't. Treaties may affect whether and when the income is taxed, but they don't switch off the information reporting requirement. Form 8938 is a disclosure obligation, and treaty benefits on the tax side don't erase it. Treating a treaty as a reason to leave the pension off the form is a classic route to a penalty.
Coordination with other forms
Depending on the structure, a foreign pension can implicate other information returns too — for example, arrangements treated as foreign trusts, or plans holding investments that raise PFIC questions on Form 8621. Where an asset is fully reported on one of those other forms, the duplicative-reporting rule means you don't re-detail it on Form 8938; you note the other form instead. Sorting out which forms apply is precisely the kind of analysis worth professional help.
This is the area we most often flag for a professional
Foreign pensions sit at the intersection of valuation difficulty, treaty interaction, and overlapping forms. If you have a foreign workplace pension of any real size, the cost of a professional review is usually small next to the risk of mischaracterizing it across several years. Nothing here is a substitute for advice on your specific plan.
