What a "specified foreign financial asset" actually is. Section 6038D(b) builds the category in two layers. The first is any financial account maintained by a foreign financial institution, and an asset held inside such an account is not separately listed, because the account already carries it. The second layer is the part people miss: assets held for investment and not held in an account. Regulation 1.6038D-3(b) names three, and the IRS fills them out with examples. Stock or securities issued by someone who is not a US person. A financial instrument or contract held for investment with a foreign issuer or counterparty, which reaches notes and bonds issued by a foreign person, swaps and options with a foreign counterparty, and a foreign-issued life insurance or annuity contract with a cash-surrender value. And any interest in a foreign entity, which covers a partnership interest in a foreign partnership, an interest in a foreign estate, and an interest in a foreign retirement or deferred compensation plan.
"Held for investment" is a real limit, not decoration. Under Regulation section 1.6038D-3(b)(3) an asset is held for investment only if it is not used in, or held for use in, the conduct of a trade or business, and the regulation spells out when an asset is instead held in a direct relationship to a business. Note also the regulation's flat rule that stock is never treated as used in a trade or business for this test.
What is not reportable, which is where most confusion lives. The IRS answers these directly. Foreign real estate held directly is not a specified foreign financial asset, so a personal residence or a rental property abroad is not reported. If that property is held through a foreign entity, the interest in the entity is reportable and the property's value feeds into the entity's value, but the property is not listed separately. Foreign currency held directly is not reportable. Directly held precious metals such as gold are not, though a gold certificate issued by a foreign person can be. Directly held tangible property such as art, antiques, jewelry, cars and collectibles is not. A foreign government's social-security-equivalent benefit is not either, but a foreign pension is, and the instructions add the distinction that matters: the social-security exclusion "does not include an interest in a foreign pension plan."
A financial account at a US payor is outside the form even when it is abroad. Regulation 1.6038D-3(a)(3)(i) excepts an account maintained by a US payor, and the instructions define that to include a domestic branch of a foreign bank or foreign insurance company and a foreign branch or foreign subsidiary of a US financial institution. So a euro account at the London branch of a US bank is not a specified foreign financial asset for Form 8938. It is still a foreign financial account for FBAR purposes, which is exactly the kind of split the table below exists to make visible.
The thresholds, and the trigger for the higher pair. Regulation section 1.6038D-2(a) sets four pairs, each with a year-end figure and a higher any-time-during-the-year figure. A single filer living in the United States reports above $50,000 on the last day of the year or $75,000 at any time; a joint return above $100,000 or $150,000. Those quadruple for a filer living abroad, to $200,000 or $300,000 single and $400,000 or $600,000 joint. The abroad test is precise and is easy to state too loosely: the regulation applies the higher thresholds to a specified individual who is a qualified individual under section 911(d)(1), which means a foreign tax home plus either the bona fide residence test or the physical presence test. A foreign tax home on its own is not enough.
You still report even if you owe no tax, and even if the asset is worth nothing. Regulation 1.6038D-2(a)(8) requires the form "even if none of the specified foreign financial assets that must be reported affect the specified person's tax liability", and 1.6038D-2(a)(5) requires reporting an asset with no positive value. Valuation generally uses the maximum value during the year, and a taxpayer may rely on periodic account statements unless they know the statements do not reflect a reasonable estimate.
The duplicative-reporting exception. An asset already reported on a timely-filed Form 3520, Form 5471, Form 8621 or Form 8865 is not listed again on Form 8938. What the taxpayer does instead is identify on Form 8938 which of those forms was filed and how many. The value of an asset excluded this way still counts toward the aggregate that decides whether the threshold is met, for an individual filer.
The penalty stack is three provisions, not one. Section 6038D(d) imposes $10,000 for a failure to furnish the information, then $10,000 for each 30-day period, or part of one, that the failure continues more than 90 days after the IRS mails notice, capped at $50,000 of continuation penalty. Section 6038D(g) allows a reasonable-cause exception, and states expressly that a foreign jurisdiction's own penalty for disclosure is not reasonable cause. Separately, section 6501(c)(8) holds the assessment period open until three years after the required information is finally furnished, which can keep an entire return open for years. And section 6662(j) raises the accuracy-related penalty from 20 percent to 40 percent for an understatement attributable to an undisclosed foreign financial asset.
Form 8938 against the FBAR, side by side. Both reports exist; neither substitutes for the other. The IRS publishes the comparison, and these are the rows that decide most real cases.
The other structural differences: the threshold is an aggregate over $10,000 at any time for the FBAR against the four Form 8938 pairs; the FBAR treats US territories as part of the United States and Form 8938 does not; and the FBAR is filed electronically with the Financial Crimes Enforcement Network, due April 15 with an automatic extension to October 15, while Form 8938 rides along with the tax return and its extensions.
