FBAR Filing for Foreign LLC Owners: Complete Guide (2026)

FBAR is not a tax form. Nothing is calculated on it and nothing is owed with it. It is a transparency filing: the US Treasury wants a yearly map of where American money sits offshore, and it has wanted one since the Bank Secrecy Act of 1970. The form is administered by the Financial Crimes Enforcement Network (FinCEN), a Treasury bureau that is not the IRS — although the IRS was delegated authority to enforce and penalise FBAR violations in 2003, which is why almost every FBAR conversation ends up sounding like a tax conversation.

That split matters more than it sounds. Because FBAR lives outside the Internal Revenue Code, it has its own definitions, its own deadline mechanics, its own penalty regime, and its own filing channel. You cannot attach it to a return, you cannot mail it, and being current on your income tax says nothing about being current on FBAR.

Three properties of the threshold catch people out, and all three are deliberate.

• It is aggregate. Ten accounts holding $1,100 each total $11,000, so all ten are reportable — even though no single account is close to the limit.
• It is peak value, not closing value. An account that briefly held $40,000 in March and finished December at $200 is measured at $40,000.
• It is a whole-year test. An account opened in February and closed in June still counts for that year, and still has to be listed.

One consequence is that a single large transaction can create an FBAR year out of nothing. A founder who routes a $60,000 client payment through a foreign business account for a week has crossed the threshold, and the fact that the money left again is irrelevant. Convert each peak to US dollars using the Treasury Reporting Rates of Exchange for December 31 of that year — not the rate on the day of the transaction.

What counts as a “foreign financial account”

The category is broader than a chequing account. It covers bank accounts, savings accounts, securities and brokerage accounts, mutual funds, most foreign life insurance and annuity policies with a cash value, and accounts held at a foreign branch of a US institution. A US branch of a foreign bank is not foreign. Directly-held foreign real estate and physical assets are not accounts and are not reported.

This is the section most FBAR guides skip, because most FBAR guides are written for American expatriates rather than for nonresidents who own US companies. The regulation at 31 C.F.R. §1010.350(b) defines a United States person to include a corporation, partnership, limited liability company, trust, or estate created, organised, or formed under the laws of the United States or any State. Ownership is not part of the test. Your Wyoming or Delaware LLC is a US person on the day it is formed, whether its member lives in London, Lagos, or Lahore.

So the question splits in two, and the answers are usually different:

The practical scenario is common and easily missed. A nonresident founder forms a Wyoming LLC, opens the US account everyone expects — and then opens a second account at a bank in Dubai, Singapore, or Estonia in the LLC’s name to receive regional payments. That second account is a foreign financial account of a United States person. If it peaks above $10,000, the LLC has an FBAR obligation in its own name and under its own EIN, even though its owner has none personally.

Note that a disregarded entity does not disappear here the way it does for income tax. FinCEN’s instructions require the entity to file in its own name; being disregarded for US income tax purposes is not a reason to skip it. That mirrors what happens with the foreign-owned disregarded entityand Form 5472, where the same “invisible” LLC is treated as a corporation solely for reporting.

Signature authority counts too

You do not need to own an account to report it. A US person with signature or other authority over a foreign account — an employee who can direct funds, a manager on a company account — reports it in Part IV of the form, even with no financial interest whatsoever.

These two are the most confused pair in cross-border compliance, largely because both report foreign money and both can be triggered by the same bank account. The cleanest way to hold them apart is that FBAR is a Treasury/FinCEN filing about accounts, while Form 8938 is an IRS filing about assets — a wider category that includes foreign stock, partnership interests, and certain contracts that FBAR never touches.

Because the thresholds differ by a factor of five and the asset definitions do not line up, all four outcomes are real: you may owe neither, one, the other, or both. Filing Form 8938 never discharges an FBAR obligation, and vice versa — the IRS says so explicitly in its own comparison table. The detail is in our Form 8938 FATCA guide.

Form 5472 is the filing that actually applies to nearly every reader of this page. It is required of a US entity that is at least 25% foreign-owned and had any reportable transaction with a foreign related party — and since funding the LLC is itself a reportable transaction, virtually every foreign-owned single-member LLC has one. FBAR, by contrast, may or may not apply depending on where the money sits.

The overlap in filers is what makes this worth stating plainly. One founder, one LLC, and three possible filings — Form 5472 for the related-party transactions, FBAR if the accounts are foreign and large enough, and Form 8938 if the founder is a US tax resident with enough foreign assets. Start from the Form 5472 guide, then confirm your own position with the do-I-need-to-file qualifier. The whole year’s obligations are laid out in the annual compliance checklist.

1. 1Test the $10,000 threshold. Add the maximum value of every foreign financial account you own or control at any single moment during the calendar year. If the combined peak tops $10,000 — even for one day — an FBAR is due. The test is aggregate and peak-value, not year-end.
2. 2Gather each account's details. For every account collect the financial institution's name and address, the account number, the account type, and the maximum value during the year converted to US dollars using the Treasury year-end rate.
3. 3Open the BSA E-Filing System. Go to bsaefiling.fincen.treas.gov and choose FinCEN Form 114. Individuals can file without registering. There is no fee. FBAR cannot be mailed or attached to a tax return.
4. 4Complete FinCEN Form 114. Enter the filer's identifying details in Part I, then one Part II entry per account you own outright and one Part III entry per jointly-owned account. If you only have signature authority, use Part IV.
5. 5Sign and submit electronically. Sign in the electronic signature block, submit, and save the BSA tracking ID confirmation. Keep account records for five years. The deadline is April 15, with an automatic extension to October 15 that requires no request.

Two mechanical points are worth repeating because they generate the most avoidable errors. First, the October 15 extension is automatic — you do not request it, and there is no form to file, which also means there is no Form 7004 equivalent to get wrong. Second, if someone else files on your behalf, they need FinCEN Form 114a on file authorising them; it is not submitted with the FBAR but must be retained.

The willful/non-willful distinction is the whole ballgame, and the gap between the two is enormous. A non-willful violation is a failure the filer did not know about or did not understand. A willful one involves a voluntary, intentional disregard of a known duty — including “wilful blindness,” which is how a filer who ticked the foreign-account box on Schedule B and then filed no FBAR ends up in the expensive column.

Voluntary correction is almost always cheaper than discovery, and the two mainstream routes divide neatly on one question: was the underlying income reported?

• Delinquent FBAR Submission Procedures. For filers who have no unreported income and are not under examination. You e-file the late FBARs through the BSA system and select a reason for filing late. FinCEN states it will not impose a penalty where the income was properly reported and taxed.
• Streamlined Filing Compliance Procedures. For non-willful filers who also have unreported income. The domestic version carries a 5% miscellaneous offshore penalty; the foreign-resident version carries none. Both require a signed non-willfulness certification.
• Voluntary Disclosure Practice. The route for potentially willful conduct, which is criminal-exposure territory and belongs with a qualified attorney, not a filing service.

Choosing between them is a judgment about your own facts, and getting it wrong is costly in both directions — a willful filer who uses the streamlined route has certified something untrue. If there is any doubt about which side of the line you are on, that is a conversation for a cross-border tax attorney before anything is filed. The mechanics of proactive correction on the IRS side are covered in our penalty abatement and relief guide.

It is worth being blunt about relative risk. For most foreign founders reading this, FBAR turns out not to apply — the LLC banks in the US, the owner is a nonresident, and there is no foreign account in the company’s name. Form 5472 applies to almost all of them, every single year, and carries the larger and more automatic penalty. Spending an afternoon on FBAR while the 5472 goes unfiled is the wrong trade.

form5472.tax prepares, reviews, and files Form 5472 with the pro forma Form 1120 for a flat $299 — against $547 at form5472.online and $1,999/year at doola. Compare the options on the pricing page, or start on the apply page. We do not prepare FBARs; if your LLC has foreign accounts over the threshold, file Form 114 yourself at bsaefiling.fincen.treas.gov, or work with a cross-border practitioner.
