Do I need to report my UK house on a missed FBAR?

No. UK real property held directly in your own name is not a foreign financial account. IRM 4.26.16 places real estate, and an arrangement holding solely real estate, outside the financial account definition, so a London flat or a buy-to-let never appears on Form 114 and no exception has to be claimed. The rental income still belongs on your US return, and if the property sits behind any arrangement involving a UK financial institution account, that account is reportable in its own right.

Are directly held UK shares reportable on the FBAR?

Not if you hold them in registered form. The IRS FBAR Reference Guide states that individual bonds, notes or stock certificates held by the filer are not a financial account. Where your own name is entered on the company's register of members, there is no account and nothing to report. Where the same shares sit in a nominee, custody or platform account with a UK broker or wealth manager, the account itself is reportable at its whole value and the underlying holdings become irrelevant to the form.

Where in the regulations are the FBAR reporting exceptions actually set out?

At 31 CFR 1010.350(c)(4), subdivided (i) through (iv): accounts of United States governmental bodies, Indian Tribes, States and their instrumentalities; accounts of an international financial institution of which the United States government is a member; accounts at a United States military banking facility; and correspondent or nostro accounts used solely for bank-to-bank settlements. Commentary frequently cites paragraph (g), which is in fact headed Special rules. Verify the lettering on the current eCFR text before relying on any secondary summary.

Is gold stored in a UK vault reportable on Form 114?

It depends on the contract, not the label. Precious metals held directly are not a financial account, and a plain safe deposit box where the institution has no right to access or dispose of the contents falls outside the form under IRM 4.26.16. Where a UK vault operator holds allocated metal under a custody arrangement permitting it to value, transfer or otherwise deal with the metal on your instruction, the relationship is an account and it is reportable. Read the clauses on access, valuation and disposal.

Does a nil or very small UK balance still go on the form?

Yes, once the threshold is met. The IRS tests the aggregate value of all foreign financial accounts at any time during the calendar year against 10,000 US dollars. Once that combined total is exceeded, every reportable account is listed regardless of its individual size, including dormant accounts and accounts holding a few pounds. Sterling denomination makes no difference, because the regulation asks where the account is maintained, and inactivity makes no difference either while the account remains open.

What records should I keep for an item I concluded was not reportable?

31 CFR 1010.420 requires records for reportable accounts showing the name in which the account is maintained, the number, the name and address of the institution, the type of account and the maximum value during the period, retained for five years and available at all times for inspection. An item that is not an account at all never enters that regime, but you should still hold the evidence establishing the characterisation: title documents, register of members entries, custody or storage contracts, loan agreements, and a dated note of the source relied on.

Missed FBAR: Which UK Accounts Are Not Reportable

A missed FBAR history is rebuilt by first deciding what does not belong on the form, and for most UK-resident Americans the answer is that a directly owned London flat, shares held in registered form, physical currency, directly held gold and an unsecured loan to a UK trading company are not foreign financial accounts at all. A second and entirely separate category exists: holdings that genuinely are foreign financial accounts, which the FinCEN regulation at 31 CFR 1010.350(c)(4) then relieves from reporting. Keeping those two categories apart is the difference between a defensible catch-up and a guess.

That distinction is not academic. In a catch-up covering several years, every line you add to Form 114 is a line you must value, source and defend, and every line you leave off is one you must be able to justify. The Financial Crimes Enforcement Network draws the boundary in two different places for two different reasons, and the note you write in the file is different in each case. One is a definitional question about whether an account exists at all. The other assumes an account exists and then carves it out. Collapsing them into a single list of exceptions, which is what almost every published summary does, is the most common structural error we see in reconstructed filings.

What does a missed FBAR filing actually have to capture?

The reporting duty in 31 CFR 1010.350(a) attaches to a United States person with a financial interest in, or signature or other authority over, a bank, securities or other financial account in a foreign country. The IRS page titled Report of Foreign Bank and Financial Accounts (FBAR) on irs.gov states the trigger plainly: an FBAR is required where the aggregate value of those foreign financial accounts exceeded 10,000 US dollars at any time during the calendar year. The same page confirms the annual filing is due 15 April following the calendar year reported, with an automatic extension to 15 October.

The operative word throughout is account. Paragraph (c) of the regulation sets out the reportable types: a bank account, meaning a savings deposit, demand deposit, checking or any other account maintained with a person engaged in the business of banking; a securities account, meaning an account with a person in the business of buying, selling, holding or trading stock or securities; and a residual class of other financial account reaching, among other things, deposits accepted as a financial agency, insurance and annuity policies with a cash value, futures and options broker accounts, and interests in mutual funds or similar pooled vehicles. If what you own is not held through one of those relationships, the reporting duty does not engage, however large the value and however obviously British the asset.

Which UK assets are not foreign financial accounts at all?

This is the first door out, and it is definitional. The Internal Revenue Manual at IRM 4.26.16, the IRS material governing FBAR examination, lists items that are not a financial account for these purposes at IRM 4.26.16.2.2. Read alongside the IRS FBAR Reference Guide, the practical list for a wealthy American in the United Kingdom looks like this.

UK real property held directly in your own name, including a London flat or a buy-to-let, and an arrangement that holds solely real property.
Shares, gilts, corporate bonds and other securities held directly in registered form, where your own name sits on the issuer's register or on a certificate rather than inside a broker's client account.
Physical currency held personally, such as sterling notes in a domestic safe or a private strongbox.
Precious metals, precious stones and jewels held directly, together with art, antiques and collectibles kept as chattels rather than through a custodian.
An unsecured loan you have made to a UK trade or business that is not itself a financial institution.
A plain safe deposit box, where the UK institution rents you space and has no right to access, value or dispose of what is inside.

UK real property is the cleanest case. A flat in Marylebone is not an account, and it does not become one because it is worth several million pounds or because it produces rent. IRM 4.26.16 puts real estate, and an arrangement holding solely real estate, outside the financial account definition. The rent is of course income and belongs on the return; the mortgage is a liability and never reaches Form 114 in any event, because the form captures account values rather than debts.

Directly registered securities are where high-net-worth UK-resident Americans most often go wrong, and they go wrong in both directions. The IRS FBAR Reference Guide states that individual bonds, notes or stock certificates held by the filer are not a financial account. If you hold shares in a private UK company as a registered member, with your name entered on the company's register of members and a share certificate behind it, there is no account and nothing to report on Form 114. The moment those same shares are moved into a nominee arrangement with a UK broker, wealth manager or investment platform, the position reverses completely. The reportable item becomes the account, valued as a whole, and the identity of the underlying holdings becomes irrelevant to the form.

Physical assets follow the same logic. Gold bars in a private safe, a watch collection, British paintings and sterling banknotes are owned outright rather than held through a financial relationship. What converts them is custody. If a UK vault operator holds allocated metal for you under a contract permitting it to value, transfer, sell or otherwise deal with the metal on your instruction, that is an account relationship and it is reportable. If the same operator merely rents you a sealed box that only you may open, IRM 4.26.16 treats it as a safety deposit box and it falls outside the form. Read the storage contract, not the marketing brochure.

The unsecured loan point is narrow and worth stating precisely. Per the IRS FBAR Reference Guide, an unsecured loan to a foreign trade or business that is not a financial institution is not a financial account. A 400,000 pound advance to a friend's UK engineering company on a simple loan note is therefore outside Form 114 entirely. Lend the same money through a UK peer-to-peer lending platform that holds your funds in a client money account and the platform account is squarely reportable, because you have interposed a financial relationship that did not previously exist.

When does a UK asset stop being outside the form?

One question resolves nearly every borderline case: does a UK institution stand between you and the asset with the ability to hold, value or deal with it on your instruction? Direct ownership means there is nobody to name in the institution fields on Form 114. Once a platform, nominee, custodian or broker sits in the chain, those fields have an obvious answer, and that is your signal that an account exists.

Two consequences follow that filers routinely miss. First, the account is reportable even where every asset inside it would have been non-reportable if held directly, so a UK platform holding nothing but directly issued corporate bonds is still a securities account. Second, the account is reportable at its whole value; you do not disclose the underlying line items and you do not net anything off. A single wrapper can therefore convert a long list of excluded assets into one reportable account. In a catch-up the wrapper, not the asset, is the unit of analysis, and an inventory built asset by asset rather than account by account will produce the wrong answer even when every individual characterisation is right.

Which UK accounts are excepted by the FinCEN rules?

This is the second door, and it operates differently. Here the holding genuinely is a foreign financial account, and the regulation then relieves it from reporting. A great deal of online commentary places these exceptions at paragraph (g) of the regulation. Check the source before you repeat it. On the current eCFR text, paragraph (g) is headed Special rules, while the account-type exceptions sit at 31 CFR 1010.350(c)(4), subdivided (i) through (iv). Getting the citation right matters when you are writing a position into a file that an examiner may later read.

An account of a department or agency of the United States, an Indian Tribe, or any State or political subdivision of a State, or a wholly-owned entity, agency or instrumentality of any of those bodies, at 31 CFR 1010.350(c)(4)(i).
An account of an international financial institution of which the United States government is a member, at 31 CFR 1010.350(c)(4)(ii).
An account in an institution known as a United States military banking facility, or United States military finance facility, operated by a United States financial institution designated by the United States Government to serve United States government installations abroad, at 31 CFR 1010.350(c)(4)(iii). The regulation states expressly that such an account need not be reported even though the facility is located in a foreign country.
Correspondent or nostro accounts that are maintained by banks and used solely for bank-to-bank settlements, at 31 CFR 1010.350(c)(4)(iv).

Read that list honestly against a private client's UK holdings and almost none of it applies. An investment banker living in Kensington will not hold a correspondent account, and the military banking facility exception reaches a narrow population attached to United States installations. The IRS FBAR page carries the same four items in the same terms. The value of the list is therefore negative rather than positive: it demonstrates that FinCEN legislated a small, closed set of account-level reliefs, and that there is no general exception for a UK current account because it is small, dormant, denominated in sterling, held jointly, or opened long before you understood the rules. If you cannot point at a subparagraph, there is no exception.

The Form 114 instructions published on the BSA E-Filing system also allow certain account detail to be reported in reduced form in defined circumstances, so that specified items in the account parts of the form need not be completed. Confirm the current wording of that relief in the FinCEN Form 114 instructions on bsaefiling.fincen.gov before relying on it, and treat it for what it is. Reduced reporting is a filing mechanics concession, not an exclusion. An account reported in reduced form has still been reported, the underlying records still have to exist, and the account still counts towards the aggregate threshold.

A worked example: one UK asset list, two reasons to exclude

Take a composite client we will call Marcus Ellery, an American citizen resident in London and a partner in a corporate finance business, who comes to us having filed no FBAR for six years. The figures below are illustrative and self-computed to show the method rather than any real client's position.

A Marylebone flat held directly in his own name, worth roughly 2.4 million pounds.
12,000 ordinary shares in a private UK company, registered in his own name on the register of members, worth roughly 850,000 pounds.
Allocated gold held with a UK vault operator under a custody contract, worth roughly 300,000 pounds.
A UK investment platform portfolio of funds and directly issued gilts, peak value 1.9 million pounds.
A UK current account, peak value 42,000 pounds.
A UK savings account, peak value 6,000 pounds.
A dormant UK building society account, peak value 180 pounds.
A 250,000 pound unsecured loan note issued to a friend's UK engineering company.

Walk the list. The flat is out through the first door: real property held directly is not an account. The registered shares are out on the same basis, because Marcus is a member on the register and no UK institution holds them for him. The loan note is out as well, because the borrower is a trading company and not a financial institution. That removes roughly 3.55 million pounds of value from the analysis without any exception being needed, for the simple reason that none of those three items is an account in the first place.

The gold is the item that turns on documents. Marcus's custody contract permits the operator to move and value the metal on instruction, so the arrangement is an account and stays in. Had the same metal sat in a sealed box the operator could not open, it would have joined the first group. The platform portfolio is a securities account, reported at its whole 1.9 million pound peak value, notwithstanding that some of the gilts inside it would have been outside the form if Marcus had held them directly. The current account, the savings account and the dormant building society account are all bank accounts, and nothing in 31 CFR 1010.350(c)(4) touches any of them.

So the aggregate test is run on five accounts rather than on eight items, and their combined peak value comfortably exceeds the 10,000 US dollar threshold in every year under review. All five go on each year's Form 114, including the account holding 180 pounds. The three excluded items produce no Form 114 line at all, but they do produce something else that matters just as much: a written reason, which is the subject of the last two sections.

Does a dormant or nil-balance UK account still count?

Yes, once the aggregate threshold has been crossed. The IRS guidance tests the combined value of all foreign financial accounts at any point in the calendar year against 10,000 US dollars, not each account separately. Once that total is exceeded, every reportable account belongs on the form regardless of its own size. The dormant building society passbook holding 180 pounds is reportable for exactly the same reason as the 1.9 million pound platform: it is an account, it is maintained outside the United States, and the aggregate is met.

Two related beliefs deserve killing off. Sterling denomination is irrelevant, because the regulation asks where the account is maintained rather than what currency it holds; a UK account is foreign whether it holds pounds, dollars or nothing. Inactivity is equally irrelevant, because an account you have not touched since 2011 remains an open account with a maximum value, even if that value never moves. Reconstructed filings that quietly drop the small and sleepy accounts are the ones that look worst on examination, precisely because the omissions are trivial in amount and therefore difficult to explain as anything other than a filer who was not being thorough.

What records survive a conclusion that an item is not reportable?

31 CFR 1010.420 imposes a records duty on a person having a financial interest in, or signature or other authority over, a reportable foreign financial account. The records must show the name in which each account is maintained, the number or other designation of the account, the name and address of the foreign bank or other person with whom the account is maintained, the type of account, and the maximum value of each account during the reporting period. The regulation requires those records to be retained for a period of five years and kept at all times available for inspection as authorised by law. The IRS frames the same period as five years from the FBAR due date, and IRM 4.26.16 repeats it.

Here is the asymmetry that published guidance rarely draws out, and it is the practical payoff of keeping the two doors apart. An item that fails the account definition never enters the 1010.420 regime at all, because there is no account of which to keep records. An account that is a foreign financial account but is excepted under 1010.350(c)(4) is still an account, so the reasoning that removed it from the form is exactly the sort of material you want to hold and be able to produce. In a multi-year catch-up the retention clock is what makes this concrete: the years you are reconstructing sit inside a period during which records for reportable accounts are required to be available, so the file you build now is the file that will be read.

How do you document a not-reportable conclusion so it holds up?

A negative conclusion with no paperwork behind it is worth very little three years later, when the person who reached it has forgotten why. In a catch-up the omissions are as much a part of the file as the entries. We build a short memorandum for every material item excluded, and we attach the primary evidence that establishes the characterisation rather than a note recording the conclusion.

For UK real property: the title register entry or completion statement showing direct personal ownership.
For registered securities: a copy of the register of members entry, the share certificate, or a registrar statement showing your own name rather than a nominee's.
For stored metals, art or collectibles: the storage or custody contract itself, with the clauses on access, valuation and disposal marked, because those clauses decide the answer.
For a private loan: the loan note or agreement, together with evidence that the borrower is a trading business and not a financial institution.
For any excepted account: the subparagraph of 31 CFR 1010.350(c)(4) relied on, and the facts that bring the account inside it.
For every excluded item: a dated one-page note naming the source relied on, the date the guidance was consulted, and the person who signed the conclusion off.

The purpose is not tidiness. A catch-up filing is a set of assertions about six years of a complicated financial life, and an examiner reads it looking for whether the filer thought about the problem or guessed at it. A file that shows a documented, sourced reason for each omission changes the character of that conversation entirely. A file that shows only what was filed invites questions about everything that was not.

Where this sits in a wider UK compliance position

Deciding what is not reportable on Form 114 is one step in a much larger exercise. The same UK asset list feeds the income tax return, the foreign tax credit position and the other US information returns a person in your circumstances may owe, and an item that escapes the FBAR may well surface elsewhere. A directly registered UK shareholding is the obvious example: outside Form 114, but very much inside the return when it pays a dividend, and potentially relevant to other filings depending on the size and nature of the holding. Concluding that something does not go on the FBAR is never the same as concluding it does not matter.

Our practice provides comprehensive US and UK tax preparation and compliance services for Americans living in the United Kingdom, including full FBAR catch-up work: rebuilding the account inventory, characterising every holding against the regulation, preparing each year's Form 114, and assembling the documentary file that supports both what was filed and what was deliberately left off. If you are reconstructing a missed FBAR history and your asset list mixes property, directly held securities, stored physical assets, platform portfolios and private lending, the characterisation work is where the real value sits. It is worth doing once, and doing it properly.
