Is a UK currency broker a foreign financial account for FBAR purposes?

Where the broker holds a balance for you, conservative practice is yes. 31 CFR 1010.350(c)(3) treats an account with a person in the business of accepting deposits as a financial agency as an other financial account. FinCEN has not addressed currency brokers by name, so held balances, wallets and forward deposits are reported as other financial accounts rather than left off the form.

Do I report a same-day spot transfer through a currency broker on the FBAR?

A single spot transfer where no balance is held and nothing remains with the broker has the strongest argument that no account relationship exists, because the money is only in transit. That is an argument rather than published FinCEN guidance. If the broker's ledger shows funds held overnight or awaiting your instruction, treat it as a reportable account for that calendar year.

Should I report the broker's safeguarding bank account instead of the broker?

No. Under the UK Payment Services Regulations 2017 and Electronic Money Regulations 2011, the safeguarding account is opened in the broker's name and pools customer funds. You are not the owner of record and cannot instruct the bank. The FBAR names the broker as the institution and uses your client reference as the account designation.

Is money held with a UK currency broker protected by the FSCS?

The FCA has stated that funds held by payments and e-money firms are not directly protected by the Financial Services Compensation Scheme. They are protected by safeguarding, which means segregation or insurance, and customers may face loss or delay if the firm fails. This is a commercial risk to weigh separately from the US reporting question.

How do I file a late FBAR for a missed currency broker balance?

File or amend the FBAR electronically through FinCEN's BSA E-Filing System, select a reason for filing late and give a factual explanation. The IRS says it will not penalize a properly reported late FBAR where it finds reasonable cause. If income was also unreported, the Streamlined Filing Compliance Procedures, with three years of returns and six years of FBARs, are usually the route.

Does Bittner mean there is no penalty for leaving one account off an FBAR?

No. Bittner v. United States (2023) held that the non-willful FBAR penalty, up to $10,000 before inflation adjustment, applies per deficient annual report rather than per account. An incomplete report is still a violation. The willful penalty was not changed and is still measured against account balances, which is significant for a house-purchase sum.

Missed FBAR: Money Held With a UK Currency Broker

A Missed FBAR is the usual result when an American in the UK moves a house deposit, a bonus or sale proceeds through a UK currency broker and nobody treats the broker as a foreign financial account. The short answer: where the broker holds a balance for you (a wallet, a held-balance facility, or a deposit against a forward contract), conservative practice is to report it on FinCEN Form 114 as an other financial account. A same-day spot transfer with no balance left behind is the one pattern with a respectable argument that no account exists. FinCEN has not published guidance that addresses currency brokers by name, so the position is built from the regulation itself.

In the returns we prepare for high-net-worth Americans in the UK, this is one of the most consistently overlooked accounts. The client lists every bank, ISA and brokerage account, and forgets the firm that carried the largest single sum of the year. This article sets out how we analyse each type of broker relationship, what goes on the form, and how a missed year is put right.

Is money held with a UK currency broker a reportable foreign financial account?

The reporting rule is 31 CFR 1010.350, which can be read at https://www.ecfr.gov/current/title-31/section-1010.350 or https://www.law.cornell.edu/cfr/text/31/1010.350. Paragraph (a) requires each 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 to report that relationship for each year in which it exists. Paragraph (c) then defines three types of reportable account.

Bank account: a savings deposit, demand deposit, checking or any other account maintained with a person engaged in the business of banking. A UK currency broker authorised as a payment institution or e-money institution is not a bank and does not hold a deposit-taking permission, so this limb does not fit comfortably.
Securities account: an account with a person engaged in the business of buying, selling, holding or trading stock or other securities. A deliverable currency transfer is not a securities trade, so this limb does not fit either.
Other financial account: this includes an account with a person that is in the business of accepting deposits as a financial agency, and an account with a person that acts as a broker or dealer for futures or options transactions in any commodity on or subject to the rules of a commodity exchange or association. The first of these is the limb that matters for currency brokers.

An other financial account is, for this purpose, an account with a person whose business is accepting customers' money and holding or moving it on their behalf. The Bank Secrecy Act defines a financial agency broadly, at 31 U.S.C. 5312(a)(1), as a person acting for another as a financial institution, bailee, depository or agent, or acting in a similar way in relation to money. A UK currency broker receives client money into its own client-facing ledger, holds it, converts it and pays it away on instruction. That is very close to the statutory description, even though UK regulation is careful to say the broker is not taking deposits in the banking sense.

Two points of honesty are needed here. First, the regulation lists the types of account but does not set a bright-line test for when a transaction relationship becomes an account. Second, we have found no FinCEN ruling or FBAR instruction that addresses a non-bank foreign exchange firm directly. The nearest FinCEN ruling involving a foreign exchange broker, FIN-2008-R004, published at https://www.fincen.gov/system/files/guidance/fin-2008-r004.pdf, deals with whether a US intermediary was a money services business. It says nothing about whether a customer's balance with such a firm is a reportable account. Where the guidance is silent and the penalty framework is severe, the compliance answer is to report held balances.

Which currency broker arrangements create an account, and which do not?

The label on the product matters less than the facts: did the broker hold money for you, in your name on its ledger, for any period, with you able to instruct what happened to it? We sort broker relationships into four patterns.

Pure same-day spot transfer. You agree a rate, send dollars, and the broker pays sterling to your UK bank account or your conveyancer the same day or on the normal settlement date. Nothing is left behind and no balance is available to you between trades. The argument that there is no account is at its strongest here: the money is in transit under a single payment instruction, not held at your disposal. It is an argument, not a published safe harbour, and it weakens quickly if the broker opened a client profile with a standing ledger that carried a balance overnight or longer.
Held-balance or multi-currency wallet facility. The broker converts your funds and holds the sterling (or leaves the dollars unconverted) until you give a payment instruction, often days or weeks later while a completion date moves. You can see a balance, and you control it. We treat this as a reportable other financial account in every case.
Forward contract with a deposit or margin. You fix a rate today for delivery months ahead and pay a deposit, with the possibility of further margin if the market moves against the contract. The deposit is your money, held by the broker against your obligation, for a defined period. We treat the deposit balance as reportable. The forward contract itself is a separate asset for Form 8938 purposes, covered below.
Limit orders and standing instructions with funds lodged. If money has been sent to the broker to await a target rate, it is a held balance however the order is described. If no money has been lodged and the order is only an instruction, there is nothing to report until funds arrive.

The failure mode we see most often is a client who describes the whole relationship as a transfer, when the broker statement shows a deposit lodged in March, the balance paid in June, and converted sterling sitting for nine days before completion. That is not a transfer. It is an account with a six-figure deposit balance followed by a seven-figure held balance.

What about the broker's safeguarding account at a bank?

UK payment institutions and e-money institutions must protect customer money under the Payment Services Regulations 2017 (https://www.legislation.gov.uk/uksi/2017/752) and the Electronic Money Regulations 2011 (https://www.legislation.gov.uk/uksi/2011/99). The Financial Conduct Authority explains at https://www.fca.org.uk/firms/emi-payment-institutions-safeguarding-requirements that firms must safeguard relevant funds either by segregating them from all other funds they hold or by covering them with an insurance policy or comparable guarantee. The FCA's strengthened safeguarding rules, including the new CASS 15 chapter of its Handbook, took effect on 7 May 2026.

In the segregation method, the broker places customer money in a designated safeguarding account at a bank. Clients sometimes ask whether that bank account is the thing to report. In our view it is not. The safeguarding account is opened and operated by the broker, in the broker's name, pooling the funds of many customers. The customer is not the owner of record, has no legal title to the bank account and has no authority to instruct the bank. Under 31 CFR 1010.350(e)(1), a financial interest arises for the owner of record or holder of legal title, and none of the look-through rules in (e)(2) fits an ordinary customer of a regulated payments firm. The reportable relationship is the customer's own balance with the broker, and the institution named on the FBAR is the broker, not its bank.

A second point matters to anyone moving a seven-figure sum. Safeguarding is not deposit insurance. The FCA has stated in its work on the safeguarding regime that funds held by payments and e-money firms are not directly protected by the Financial Services Compensation Scheme, and that customers can lose money or face delays in getting funds back if a firm fails. That is a commercial risk rather than a tax point, but it is also evidence of the legal character of the arrangement: your claim is against the broker, which is exactly why the broker is the account-holding institution for reporting purposes.

Why does a single house-purchase transfer break the $10,000 test?

The IRS states the filing trigger at https://www.irs.gov/newsroom/details-on-reporting-foreign-bank-and-financial-accounts: a US person must file where the aggregate value of all foreign financial accounts exceeds $10,000 at any time during the calendar year. Three features of that test catch broker balances.

It is an aggregate test. The broker balance is added to every UK current account, savings account, ISA and brokerage account. Most of our clients are over the threshold before the broker is counted, so the broker question is rarely whether to file but whether the filed form was complete.
It is an any-time test. A balance held for one night counts. A house purchase routed through a held-balance facility will exceed $10,000 by a factor of a hundred or more, however briefly.
It ignores the year-end position. A broker wallet that is empty on 31 December is still reportable for the year if it held funds earlier in that year.

The due date is 15 April following the calendar year, with an automatic extension to 15 October that requires no request. The form is filed electronically through FinCEN's BSA E-Filing System at https://bsaefiling.fincen.gov, separately from the federal income tax return. FinCEN's own FBAR page at https://www.fincen.gov/report-foreign-bank-and-financial-accounts links to the line item filing instructions.

How is the maximum value of a currency broker balance calculated?

The FBAR asks for the maximum value of each account during the year, not the closing balance. The IRS guidance cited above says filers figure the greatest value in the currency of the account and convert it into US dollars using the Treasury Bureau of the Fiscal Service exchange rate for the last day of the calendar year. Those rates are published at https://fiscaldata.treasury.gov/datasets/treasury-reporting-rates-exchange/. The rate actually achieved on your transfer is irrelevant to this figure, which regularly surprises clients who have a contract note showing a different rate.

The Internal Revenue Manual at https://www.irs.gov/irm/part4/irm_04-026-016 describes the maximum value as the largest amount of currency and non-monetary assets appearing on any quarterly or more frequent account statement for the year. Currency brokers do not always issue periodic statements in the way a bank does. In practice we ask the broker for a full transaction history or ledger export for the client reference and take the highest balance from that. Where a broker keeps separate ledgers by currency under one client reference, we report the peak of each currency ledger converted at the year-end rate, and we keep the working papers showing how the figure was derived.

What account number and institution details go on the FBAR?

The IRS says filers must keep, for five years from the FBAR due date, the name on each account, the account number or other designation, the name and address of the foreign institution, the type of account and the greatest value during the year. For a currency broker, those items translate as follows.

Type of account: other, with a short description such as currency broker held balance or forward contract deposit. It is not a bank account and should not be labelled as one.
Financial institution name and address: the legal name and registered UK address of the broker entity you contracted with, taken from its terms of business or the FCA Register, not the name of the bank where its safeguarding account is held.
Account number or other designation: the client reference, account ID or wallet number the broker uses for you. If the broker issued you named virtual account details for paying in, record those in your file, but the identifier of your relationship with the broker is the client reference.
Joint relationships: where spouses are both named on the broker facility, each US-person spouse has a financial interest and the account appears as jointly owned.

Worked scenario: a London house purchase through a forward contract

This is an illustration with assumed figures and an assumed exchange rate, not a client case. A US citizen resident in London agrees to buy a house and sells US investments to fund it, leaving $2,000,000 to convert. In March she books a forward contract with a UK currency broker to fix the rate for a June completion and pays a 5% deposit of $100,000. In June she pays the remaining $1,900,000. The broker converts the whole $2,000,000 at an assumed rate of 0.80 pounds per dollar, producing 1,600,000 pounds, which sits in her sterling wallet for nine days because completion slips. The broker then pays her conveyancer. A residual balance of 12,000 pounds stays in the wallet at 31 December.

On these facts the broker relationship is reportable for the year. The dollar ledger held $100,000 from March to June and peaked when the balance arrived. The sterling ledger peaked at 1,600,000 pounds. Assuming, purely for illustration, that the Treasury year-end rate is also 0.80 pounds per dollar, the sterling peak converts to $2,000,000. In a real year the Treasury rate will differ from the contract rate and the reported figure will differ from the dollars she actually sent. The account type is other, the institution is the broker, and the designation is her client reference. The closing 12,000 pounds does not reduce the maximum value. If she filed her FBAR listing only her bank and investment accounts, she filed an incomplete report, and the following year the residual wallet balance creates the same question again.

Does the same balance go on Form 8938, and what about the currency gain?

Form 8938 is a separate regime with different thresholds, set out by the IRS at https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements. For taxpayers living abroad, the form is required where specified foreign financial assets exceed $200,000 on the last day of the tax year or $300,000 at any time for single and married-filing-separately filers, and $400,000 on the last day or $600,000 at any time for joint filers. A seven-figure broker balance can carry a household over the any-time limb in a year when it would otherwise have been under.

Whether a non-bank broker balance is a financial account maintained by a foreign financial institution, or an interest in a contract with a foreign counterparty, is a technical classification question for the preparer. Either way, we include a held balance, and we consider separately whether an open forward contract at year end is a reportable contract with a non-US counterparty. Filing Form 8938 never replaces the FBAR: the IRS comparison page is explicit that both may be required for the same asset.

The conversion itself is a separate return issue. Holding sterling and then spending it on a house, or closing out a forward contract, can produce a currency gain or loss under Internal Revenue Code Section 988, measured in dollars between acquisition and disposal of the currency. That belongs on the income tax return, not the FBAR, and we cover it in separate articles on this site. The practical link is that the same broker ledger supplies the figures for both.

How do you fix a Missed FBAR for a currency broker balance?

The remedy depends on what else is wrong. Where the only defect is that the FBAR was not filed, or was filed without the broker balance, and all related income was reported on the tax return, the FBAR is filed or amended late through the BSA E-Filing System. The electronic form asks the filer to select a reason for filing late and allows a written explanation. The IRS states that it will not penalize those who properly report a foreign financial account on a late-filed FBAR where it finds they have reasonable cause for the late filing. The explanation should be factual: what the arrangement was, why it was not recognised as an account, and when the omission was identified.

The IRS formerly published a named delinquent FBAR procedure for this situation. That page was withdrawn around 1 July 2026 and should not be relied on as a current route. Late FBARs are filed through BSA E-Filing with a reason, or as part of a streamlined submission.

Where the missed broker balance sits alongside unreported income, such as an unreported Section 988 gain, interest, or wider unfiled returns, the Streamlined Filing Compliance Procedures are usually the relevant route. The IRS sets out the foreign offshore version at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states. It requires tax 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, and a certification on Form 14653 that the failures resulted from non-willful conduct. The IRS defines non-willful conduct as conduct due to negligence, inadvertence or mistake, or conduct that results from a good faith misunderstanding of the requirements of the law. A taxpayer who qualifies and complies is not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties under that procedure. Not recognising a currency broker as an account-holding institution, where FinCEN has never said so in terms, is the kind of fact pattern the non-willful definition describes, but the certification is a statement of the taxpayer's own facts and has to be accurate for that taxpayer.

What penalties apply to a non-willful Missed FBAR after Bittner?

The IRS comparison page states the civil FBAR penalty as up to $10,000 if non-willful, and, if willful, up to the greater of $100,000 or 50 percent of account balances. Those statutory amounts are adjusted for inflation. Criminal penalties also exist for willful violations.

In Bittner v. United States, decided by the Supreme Court on 28 February 2023, the Court held by five votes to four that the non-willful penalty applies once per report, not once per account. That matters directly here. Leaving a currency broker off an FBAR that was otherwise late or deficient does not create an additional non-willful penalty for that account: the violation is the deficient annual report. Bittner did not change the willful penalty, which is still measured by reference to account balances, and a seven-figure house-purchase balance makes that calculation serious. It is the reason we do not regard leaving a held balance off the form as a defensible economy.

A preparer's checklist for broker balances

Ask every client, every year, whether money moved between currencies and through whom. Do not rely on a list of bank accounts.
Obtain the broker's full ledger or transaction history for the client reference, not just contract notes.
Identify whether funds were ever held: forward deposits, margin, converted funds awaiting instruction, residual balances.
Record the broker's legal entity name and UK address and the client reference as the account designation.
Compute the maximum value per currency ledger and convert at the Treasury year-end rate.
Test the Form 8938 any-time threshold with the broker balance included.
Pass the same ledger to whoever computes the Section 988 result on the income tax return.
If prior years are missing the broker, decide between a late or amended FBAR with a reason and a streamlined submission before filing anything piecemeal.

This article describes how we prepare and file these forms. It is general information on compliance and is not a substitute for a review of your own broker documents and filing history.
