Do I need to file an FBAR if the company account never held any of my own money?

Yes. The FBAR is triggered by signature or other authority over a foreign account, not by whose money it holds. If you are on the bank mandate for your UK company's account, you report it once your total foreign balances exceed $10,000 at any point in the year, even though every pound belongs to the business.

What exchange rate do I use to value a UK account for the FBAR?

Convert each account's highest balance for the year into US dollars using the US Treasury's year-end exchange rate for that year. Use the same rate consistently across all accounts for a given year, and keep a note of the rate and its source so your figures can be defended later if anyone asks.

How many years of missed FBARs do I usually have to file?

The FBAR carries a six-year window, so catch-up filings generally cover up to the past six years. Under the Streamlined Procedures you file six years of FBARs along with the required amended or delinquent returns. The exact years depend on your facts, so confirm the scope with an adviser before you file.

Will filing late FBARs trigger an audit?

Filing late does not automatically trigger an audit, and coming forward voluntarily is viewed far more favourably than being caught first. The bigger risk is doing nothing, or filing inconsistent reports in a hurry. A clean, well-documented catch-up with a coherent explanation is your best protection against trouble.

I am a director but own no shares. Does that change anything?

It can simplify your position. Without shares you generally have signature authority but no financial interest, so you still file the FBAR but may avoid Form 5471 and the ownership-based reporting. When listing the account you would tick the signature-authority box rather than the financial-interest box.

Can my UK accountant handle my missed FBAR?

Most UK accountants do not handle US filings, and the FBAR is a US obligation filed through a US electronic system. You need an adviser who works across both systems and understands the Streamlined and reasonable-cause routes. US-UK Tax Advisors specialises in exactly this kind of cross-border catch-up work.

Missed FBAR on a UK Company Account You Direct

You moved to London years ago, set up a UK limited company, and your accountant opened a business current account in the company's name. You are listed at Companies House as a director, and your signature is on the bank mandate so you can authorise supplier payments. It never occurred to you that a US tax form could be lurking behind that arrangement. Then a colleague mentions the FBAR over coffee, and the ground quietly shifts under your feet.

A missed FBAR is one of the most common surprises we see among US citizens running a British business. The reporting duty does not care whose money sits in the account. It attaches to you personally, as a US person, the moment you can sign on a foreign financial account, even if every pound in it belongs to the company. This article walks through who must file, how a directorship pulls you into the net, the realistic ways to put things right, and how FBAR interacts with the other forms an owner-director often owes.

Who actually has to file an FBAR?

Any US person whose foreign financial accounts add up to more than $10,000 at any point in the calendar year must file an FBAR. A US person means a US citizen, a green card holder, or a US tax resident, wherever in the world they actually live. The form itself is FinCEN Form 114, the Report of Foreign Bank and Financial Accounts, and it is filed electronically through the BSA E-Filing System rather than attached to your tax return. It is due on 15 April, with an automatic extension to 15 October that you do not have to request.

Two separate things can create a filing duty: a financial interest in an account, or signature or other authority over it. Most people assume only the first matters, the account you own with your name and your money. But the second category catches directors, officers, and employees who can move money that belongs to someone else. That is exactly where a US citizen sitting on the board of a UK company tends to get caught out, because the authority is real even when the ownership is not.

What counts as signature or other authority over a UK business account?

Signature or other authority means you can control the disposition of money in the account by delivering an instruction to the bank, whether alone or together with someone else. In plain terms, if the bank will act on your signature or your online banking authorisation to pay money out, you have authority over that account. It does not matter that the funds are the company's, that another director has to co-sign, or that you have personally never moved a single penny. The capacity to instruct is what counts.

Being named on the bank mandate for the company's current account
Holding online banking credentials that let you approve or release payments
Being a cheque signatory, even as a backup who rarely signs
Having a company debit card or corporate card drawn on the account
Authority to instruct wire transfers or standing orders, alone or jointly

A UK limited company almost always needs at least one director who can operate the bank account day to day. If that director is a US person, the authority test is usually met the moment the mandate is signed. The real question then becomes whether the balances are large enough to require a report, not whether a report is even conceptually in play. For most trading companies, the answer to the balance question is yes.

Does a UK Ltd director really trigger a Missed FBAR?

Yes, a US-person director with signing power over a UK company's bank account can absolutely end up with a missed FBAR, and it happens all the time. The confusion usually comes from a reasonable but wrong assumption: that the FBAR only covers personal accounts. Because the company account holds the company's money, people file nothing, and the obligation quietly goes unmet year after year. There is a narrow relief for certain employees of entities that already report, but it is limited and does not reach the owner-director of a small British company. For the typical US founder or co-director of a UK Ltd, the safe working rule is simple: if you can sign, you count the account. You report its highest value during the year and tick the box showing signature authority, and where you also hold shares, a financial interest as well.

How does the $10,000 aggregate threshold work?

The $10,000 threshold is aggregate, not per account, and it looks at the highest balance each account reached during the year rather than the balance on any single day. You add together the peak value of every foreign financial account you own or can sign on, and if the combined figure tops $10,000 at any moment in the calendar year, every one of those accounts becomes reportable, including the ones with trivial balances. Two traps follow from this. First, the account does not have to stay above $10,000 for long; a single day at the top of its range is enough to pull in the whole year. Second, personal and business accounts go into the same pot: your own current account, a dormant savings account, and the company's business account are all added together. Many directors clear the threshold on the business account alone, because trading receipts, VAT held back for the quarter, and a corporation-tax reserve can stack up fast.

A worked example: when a modest business account crosses the line

Consider Dana, a US citizen living in Bristol who co-founded a UK consultancy set up as a limited company. She is a Companies House director and is named on the business current account so she can pay suppliers. During the year the account opened at around £4,000, climbed to a high of £62,000 in September when two client invoices settled just before the quarter's VAT and corporation tax were paid, then fell back by December. The money was never really hers, and most of it was spoken for within weeks.

Dana also keeps a personal UK current account that peaked at about £3,500 during the year. At roughly 1.27 dollars to the pound, the business account's September high converts to about $78,700 and her personal account to about $4,450. The peak balances are what matter, so her aggregate is roughly $83,150, far above the $10,000 line. Dana has to file an FBAR reporting both accounts, using each account's own highest balance for the year. The fact that the £62,000 was earmarked for tax and gone within weeks changes nothing; the high-water mark is the figure FinCEN wants to see.

What are the realistic routes to fix a Missed FBAR?

The two realistic routes to correct a missed FBAR today are the IRS Streamlined Filing Compliance Procedures, if you qualify, or a straightforward delinquent filing accompanied by a reasonable-cause statement. The old Delinquent FBAR Submission Procedures that many older articles still describe as a tidy standalone program should not be relied on as a current, published route; it is no longer presented that way, and building a strategy around it is risky.

Which path fits depends mainly on whether you also under-reported income. If your US returns were otherwise correct and you simply never filed the FBARs, you may be able to e-file the late reports through the BSA system and attach a clear explanation of why they are late. If there is unreported income, which is common when a company pays dividends or the structure was never reported properly, the Streamlined route is usually the better fit because it brings both the returns and the FBARs back into line at once.

Streamlined Foreign Offshore Procedures: for US persons who meet a non-residency test, typically those genuinely living in the UK; the miscellaneous offshore penalty is waived for eligible filers
Streamlined Domestic Offshore Procedures: for US persons who do not meet the non-residency test and are effectively based in the States
Both require that the failure to file was non-willful, and ask for amended or delinquent returns plus up to six years of FBARs
Both demand a signed certification explaining, honestly and specifically, why the omission was non-willful

Eligibility is not something to guess at. The non-residency test, the number of years in scope, and the certification language all have to be right, and a weak or boilerplate explanation can do real damage to your position. This is the point at which most directors should bring in a cross-border specialist rather than improvise, because the route you choose shapes everything that follows.

Willful or non-willful: where does a forgetful director sit?

Most directors who simply never knew about the FBAR fall on the non-willful side of the line, but the distinction is factual and matters enormously. Non-willful means the failure was not a voluntary, intentional disregard of a known legal duty, the honest 'I had no idea' case. Willful is broader than outright fraud: it covers intentional conduct and also reckless disregard, such as suspecting a duty existed and then deliberately choosing not to look into it. The penalty framework tracks that gap. Non-willful violations carry a civil penalty capped by statute and adjusted for inflation, and following a recent Supreme Court decision that penalty is generally assessed per annual report rather than per account. Willful violations expose the person to a far larger penalty measured against the account balance. Reasonable cause, meaning a genuine and well-documented reason for the failure, can reduce or remove penalties, which is why the explanation you give is the heart of the case rather than a formality. Coming forward before the IRS contacts you keeps the gentler routes open; waiting until you are already under examination can shut them.

What about Form 5471 and Form 8938 if you also own the company?

If you own shares in the UK company, not just sign on its account, you are usually into Form 5471 and sometimes Form 8938 territory as well, and these sit alongside the FBAR rather than replacing it. Form 5471 is the information return for US persons who are officers, directors, or shareholders in certain foreign corporations, and a US owner-director of a UK Ltd frequently has to file it; the penalties for a missed 5471 are steep and entirely separate from anything FBAR-related. Form 8938, the Statement of Specified Foreign Financial Assets, is filed with your Form 1040 when your foreign assets exceed thresholds that are higher than the FBAR's and that differ depending on whether you live in the UK or the US. The FBAR and Form 8938 overlap but are not duplicates; they go to different places, use different thresholds, and both must be filed when both apply. A proper catch-up looks at FBAR, 5471, and 8938 together, because fixing one and ignoring the others leaves the exposure only half closed.

How do you reconstruct records for years you never tracked?

Start by pulling the full statement history for every foreign account, because the FBAR asks for the maximum value each account reached in each year, a figure you can only defend with the underlying statements. UK banks can usually provide several years of statements through online banking or on request, and Companies House filings help you confirm when you became a director and which accounts existed in each period. Treat this as evidence-gathering, not guesswork.

Request complete annual statements for every UK personal and business account, going back at least six years
For each account and each year, identify the single highest balance shown on the statements
Convert each peak figure to US dollars using the US Treasury year-end rate the FBAR expects
List every account where you are a signatory, including company accounts you think of as not yours
Confirm your directorship dates and shareholdings from Companies House to scope any Form 5471 duty
Keep a written timeline of what you knew and when, to support a non-willful or reasonable-cause position
Have a cross-border adviser review eligibility and the route before you file anything

Do not file piecemeal in a panic. A rushed set of FBARs with inconsistent figures, submitted without first deciding on the right disclosure route, can undercut the very non-willful story you need to tell. Reconstruct the numbers first, choose the route second, then file as a single coherent package so your returns, FBARs, and any information forms all tell the same story.

Putting a Missed FBAR behind you

A missed FBAR on a UK business account is a common and fixable problem, not a sign that you have done something sinister. The reporting duty follows your signature, not your money, so a US-person director of a UK limited company usually has to report the company account once total foreign balances top $10,000 at any point in the year. The good news is that the correction routes, Streamlined where you qualify or a careful delinquent filing with a reasonable-cause explanation, are designed for exactly this situation, provided you act before the IRS comes to you.

Because the FBAR so often travels with Form 5471 and Form 8938 for owner-directors, the safest move is to map the whole position once and fix it in a single consistent filing. If you are a US citizen in the UK who has just realised your company account should have been on an FBAR for years, speak to a cross-border specialist at US-UK Tax Advisors before you file anything. Getting the route and the certification right the first time is what turns a worrying backlog into a closed chapter.
