A missed FBAR is easy to picture when it involves a forgotten savings account at a UK bank, and much harder to spot when the money never really felt like yours to hold - it sat, for a matter of days or weeks, in a solicitor's client account during the purchase or sale of a property. A US person who moved several hundred thousand pounds of completion money through a conveyancer in London will often have no idea that the brief passage of those funds through a foreign account could, on the right facts, have created a reporting obligation on FinCEN Form 114. This is one of the genuinely difficult edges of the FBAR regime, and it rewards a careful look rather than a confident assumption in either direction.
The question is not whether the solicitor did anything wrong - they almost certainly did not - but whether you, as the beneficial owner of money held in their name at a UK bank, had a reportable financial interest in a foreign financial account during the year the transaction completed. The answer turns on how the money was held, for how long, and in what kind of account, and it is fact-specific enough that it belongs in front of an adviser rather than being settled by a blog. What follows explains the moving parts so you can see why, and work out whether your own conveyancing year is one to look at again.
How can a solicitor's client account lead to a missed FBAR?
When you buy or sell UK property, large sums pass through your solicitor's hands. The deposit on exchange, the balance of the purchase price on completion, or the net proceeds of a sale will typically be received into and paid out of a client account - a bank account the law firm holds at a UK bank, in its own name, ring-fenced from the firm's own money and holding funds that beneficially belong to clients. For a few days or weeks, a slice of that account represents your money.
If you are a US person, the FBAR regime does not care that the money was only passing through, nor that a regulated professional controlled it. It asks a narrower question: during that calendar year, did you have a financial interest in, or signature or other authority over, a foreign financial account, and did your foreign accounts in aggregate top 10,000 dollars at any point? A conveyancing transaction can answer yes to both halves of that question, and a filer who never thought of the solicitor's account at all ends up with a missed FBAR without ever opening a foreign bank account in any ordinary sense.
What does the FBAR require, and what is a "financial interest"?
The FBAR - the Report of Foreign Bank and Financial Accounts, filed electronically as FinCEN Form 114 - must be filed by a US person who has a financial interest in, or signature or other authority over, one or more financial accounts located outside the United States, where the aggregate value of those accounts exceeded 10,000 dollars at any time during the calendar year. US person covers US citizens, lawful permanent residents and others treated as US residents for tax purposes. The threshold is tested on the combined maximum of every reportable account, not account by account, and it is tested in US dollars.
Financial interest is the concept that matters most here. The FinCEN rules give a US person a financial interest not only in an account they own of record or hold legal title to, but also in an account whose owner of record or holder of legal title is acting as that person's agent, nominee, attorney, or in some other capacity on their behalf. That agency language is a close description of a solicitor holding your money. Signature or other authority is a different trigger - the power to control the disposition of funds by dealing directly with the bank - and it usually points the other way in a conveyancing case, because the one person who cannot instruct the bank about a client account is you. The client has no signing power over it; only the firm does. So if a solicitor's account is reportable by you at all, it is almost always because of a financial interest through the firm's agency, not because of signature authority.
Is money in a solicitor's pooled client account reportable?
This is where honesty matters more than a slogan. Most UK firms operate a general client account - a single pooled account at a UK bank that holds money belonging to many clients at once. Your completion money sits in it alongside dozens of other people's funds, you are not the owner of record, and no discrete sub-account bears your name. Whether a US client has a reportable financial interest in that pooled account is genuinely contestable. The agency rule in the FinCEN regulations can be read to reach it, because the firm holds the money on your behalf; but a pooled account holding many clients' money, in which you cannot point to a ring-fenced balance that is your own account, does not map cleanly onto the form's model of an account with an owner and a maximum value.
The practical difficulties track the legal ones. If you did have a financial interest in the pooled account, what is its maximum value - the whole pooled balance, which is mostly other clients' money, or only your slice of it? The form is built around an account you can value, and a commingled client account resists that. Reasonable advisers land in different places on the general pooled account, and there is no Treasury guidance that settles the point for conveyancing money specifically. What is not in doubt is that the question is live, that it is driven by the size and timing of your transaction, and that waving it away because the solicitor was in charge is not a safe answer.
Does a designated client account change the answer?
It can, and this is the distinction that too many quick answers miss. A designated or separate client account is opened for one client's money alone - often where the sums are large or will be held for a while - and it sits at the bank in the firm's name but for that single client, usually earning interest for them. That looks far more like an account held by the firm purely as your agent or nominee, with an identifiable holder, an identifiable balance and an identifiable maximum value. On those facts the agency rule in the FinCEN regulations has a much more natural fit, and the case for treating it as your reportable foreign financial account is correspondingly stronger.
So the same transaction can produce different FBAR answers depending on a decision the solicitor made for reasons that had nothing to do with US tax - whether to run your money through the general client account or to open a designated account for it. If you are reviewing a past conveyancing year, finding out which kind of account held your money is one of the first things worth establishing, because it materially changes how confident the analysis can be.
Does a balance that lasts only a few days really count?
Yes - and this surprises people more than any other feature of the FBAR. The amount you report for an account is its maximum value during the calendar year, the greatest the balance reached at any moment, not the balance on 31 December and not an average. A sum that lands and leaves within a single week sets that account's maximum for the entire year, and a balance that existed for one afternoon counts in full. There is no minimum holding period and no exception for brevity. Completion money is, by its nature, a spike: it arrives, it rests for days, it moves on. If the account it rested in is reportable by you, the week it sat there is enough to fix a maximum value that can dwarf everything else you hold.
How do conveyancing deposits and completion monies create the exposure?
Property transactions are built around a handful of moments when money is held for you. On exchange of contracts, the buyer's deposit - commonly ten per cent - is paid over and held pending completion. On completion, the full balance of the purchase price passes through the buyer's solicitor to the seller's side. On a sale, the net proceeds land with your solicitor before being sent on to you, redeployed into an onward purchase, or used to redeem a mortgage. Each of those is a point at which a UK account controlled by your solicitor holds money that is, in substance, yours - and for a US person those are exactly the moments when an FBAR question crystallises, because the sums almost always clear the 10,000 dollar aggregate threshold on their own and the money genuinely rests in a foreign account for a measurable period. The exposure is not created by anything unusual; it is created by an ordinary, lawful, well-run conveyance, and that is precisely why it is so easy to miss.
A worked example: £300,000 of completion money held for a week
Take a US citizen living in London - call her Dana - who sold a flat in 2024. On completion in June, the net proceeds of £300,000 were received into her solicitor's client account and sat there for about a week while an onward purchase was arranged, before being sent on to the new seller's solicitor. Dana held no other UK account above a modest current account that peaked at around £4,000 across the year. She filed no FBAR for 2024, assuming she was comfortably under the threshold.
Converted to US dollars at any plausible 2024 rate, £300,000 is several hundred thousand dollars - far above the 10,000 dollar reporting line, and on its own enough to require an FBAR for the year if that client account is reportable by her. The week it sat there is irrelevant to the threshold: the maximum value is the maximum value, whether it was held for seven days or the whole year. If Dana's money went through a designated client account opened for her sale, the case that she had a reportable financial interest is strong, and 2024 is very likely a missed FBAR year. If it went through the firm's general pooled account, the position is more arguable but cannot be dismissed, precisely because the sum is so large.
Either way, the right response is not to guess. It is to establish which account held the money, take advice on whether a financial interest existed, and - if it did - to report 2024 and look back at any earlier conveyancing years that followed the same pattern. The modest current account, incidentally, would also go on the form once the threshold is crossed, because an FBAR reports every foreign account you hold once any of them tips the aggregate over the line.
When does solicitor-held money raise an FBAR question?
The common thread is a US person who is the beneficial owner of money held, for any length of time, in a UK account controlled by their solicitor. The situations most worth examining are these:
- Completion monies on a UK property purchase passing through your solicitor's client account.
- The deposit paid on exchange of contracts and held by a solicitor pending completion.
- Net sale proceeds resting with your solicitor before being paid out to you or into an onward purchase.
- Money placed in a designated client account opened specifically for your transaction, especially where it earns interest for you.
- Retentions or stakeholder sums held back after completion - for defects, service-charge disputes or similar - sometimes for months.
- Funds held by a solicitor in a transaction other than conveyancing, such as a business sale or a litigation settlement, where you are the beneficial owner.
- Any such sum that, alone or combined with your other foreign accounts, pushes your aggregate maximum over 10,000 dollars at any point in the year.
Can I rely on my solicitor to report the account?
No. Your UK solicitor has no role in your US tax compliance and will not file an FBAR for you, and the firm's own regulatory and banking reporting does nothing to discharge your personal obligation. It is true that UK banks report US account holders to HMRC, which exchanges that information with the IRS under the intergovernmental agreement, but a pooled client account in the law firm's name is reported as the firm's account, not yours - so you cannot assume the IRS has been told about your slice of it, and you equally cannot assume your filing can be skipped. The FBAR is a personal report made by you, about accounts in which you have a financial interest or authority, and no professional in the chain carries that duty for you. If the account was reportable, only your own FinCEN Form 114 satisfies the requirement.
What are the catch-up options for a missed FBAR?
If you conclude that a conveyancing year produced a reportable account you did not report, the route back depends on the wider picture - in particular whether the income side of your US returns was correct. Where returns were filed and all income was reported, and the only gap is the missing form, late FBARs can be filed electronically with a statement of the reason they are late; the IRS asks late filers who are not under examination and have not been contacted to file as soon as possible to keep any penalty exposure to a minimum. This is not a formal standalone amnesty - the long-running Delinquent FBAR Submission Procedures no longer exist as a named program - so the explanation and the reasonable-cause record you file alongside the late reports do real work.
Where the missed FBAR sits alongside unreported income or unfiled returns, the Streamlined Foreign Offshore Procedures are usually the better home for a US person living in the UK. In outline they require:
- Amended or delinquent returns for the most recent three years for which the due date has passed.
- FBARs for the most recent six years for which the FBAR due date has passed - a longer look-back than the three-year return component.
- A signed certification that the failures, including the missed FBARs, were due to non-willful conduct.
- Payment of any tax and interest due with the submission; eligible non-US-resident filers face no separate offshore penalty under this route.
A missed FBAR arising from money that simply passed through a solicitor's client account is one of the more forgivable gaps in the system - it comes from the transaction feeling like a UK conveyance rather than the opening of a foreign account - but forgivable is not the same as ignorable, and the analysis genuinely turns on facts you may not have to hand. Whether a general pooled account, a designated account, a one-week spike or a long retention is involved, the sensible step is to pin down how your money was held and take advice before deciding you have nothing to report. If a conveyancing year did create a reporting obligation, acting before the IRS makes contact is what keeps the cheapest doors open.
