A missed FBAR on a UK employer share plan account is one of the most common gaps we correct for investment bankers and senior executives, because the plan account never feels like a bank account. If you are a US person and a UK share plan administrator, registrar or nominee holds cash or vested shares for you, that holding is capable of being a foreign financial account, and its maximum value during the year counts toward the aggregate threshold on FinCEN Form 114. The IRS states the core rule at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar and the rule is that a US person must file an FBAR if the aggregate value of their foreign financial accounts exceeded 10,000 dollars at any time during the calendar year reported. The threshold is aggregate across all accounts, not a per-account allowance, so a Save As You Earn savings balance of a few thousand pounds sitting alongside a UK current account is often enough on its own to put you over the line.
The failure mode we see most often is not ignorance of the FBAR. It is a partial FBAR. The client has been filing FinCEN Form 114 diligently for years, listing the UK current account, the offset mortgage savings pot and perhaps a stockbroker account, and has simply never thought of the Sharesave balance or the Share Incentive Plan holding as an account at all. They think of it as a benefit, a payroll deduction, or a line on the annual share plan statement that arrives with the P60. In the returns we prepare, that single omission is the reason a set of otherwise clean FBARs is incomplete for six consecutive years, and it is usually only discovered when a scheme matures and a six-figure balance appears out of nowhere.
What counts as a foreign financial account for FBAR purposes?
A foreign financial account is a financial account located outside the United States in which you have a financial interest or over which you have signature or other authority. The Internal Revenue Manual sets out the categories at https://www.irs.gov/irm/part4/irm_04-026-016, and the definition is deliberately broad. A bank account covers a savings deposit, demand deposit, checking account or time deposit. A securities account covers a securities account, securities derivatives account or other financial instruments account held with a person engaged in the business of buying, selling, holding or trading stock or other securities. Other financial accounts pull in insurance and annuity policies with a cash value, commodity futures and options accounts, and mutual funds. Nothing in that list requires the institution to call itself a bank, and nothing requires the account to be one you opened voluntarily.
- Bank accounts: savings, current, deposit and time deposit accounts held with a UK institution.
- Securities accounts: accounts held with a person in the business of buying, selling, holding or trading stock or other securities, which is exactly what a share plan administrator, registrar or nominee service does.
- Other financial accounts: insurance and annuity contracts with cash value, commodity and futures accounts, and pooled fund holdings.
- Accounts held for you by an agent or nominee, where the nominee is the owner of record but the economic benefit is yours.
- Accounts you do not own but can direct, which fall into the separate signature authority category.
- Joint accounts, where the entire account value is reported by each filer with a financial interest, not a proportionate share.
The test for whether an account is foreign is geographic, not corporate. An account maintained at a UK branch of a US bank is a foreign account for FBAR purposes, while an account at a US branch of a UK bank is not. That matters for share plans because global employers frequently use an administrator with entities on both sides of the Atlantic. What controls is where the account itself is maintained, which is the question to put to the plan administrator in writing rather than assume from the logo on the statement.
Why does a UK employer share plan account create a missed FBAR?
A UK employer share plan account creates a reporting obligation because of what actually sits inside it, not because of what it is called. Strip away the branding and a typical plan account contains a cash pool and a share pool. The cash pool holds monthly salary deductions before they are applied, cash dividends awaiting payment or reinvestment, fractional entitlement proceeds and, after a sale, the net cash proceeds until they are paid across to a UK current account. The share pool holds vested shares registered to a nominee for your benefit. Both are held with an institution in the business of holding and trading securities, in a jurisdiction outside the United States, for your economic benefit. That is a foreign financial account on the ordinary meaning of the FBAR definition.
The reason this is a high-earner blind spot rather than a beginner error is the size of the numbers. Bankers and executives on multi-year share plans routinely accumulate five and six figure balances with a share plan administrator, often more than sits in any bank account they hold, and the balance grows through payroll rather than through any transaction they consciously make. There is no debit card, no sort code, no statement that looks like a bank statement, and frequently no online banking style login. The account is invisible to the mental checklist most people run when a preparer asks whether they hold any foreign bank accounts, which is why the question has to be asked differently.
How does financial interest work when a nominee holds the shares?
Financial interest is the concept that catches share plan accounts, and it is wider than legal ownership. Under the definitions summarised at https://www.irs.gov/irm/part4/irm_04-026-016, a US person has a financial interest in an account where that person is the owner of record or holds legal title, whether the account is maintained for their own benefit or for the benefit of others. Critically, a US person also has a financial interest where the owner of record or holder of legal title is a person acting as an agent, nominee, attorney, or in some other capacity on behalf of that US person. UK employer share plans are built on precisely that structure. The administrator or its nominee company is the registered holder, and you are the beneficial owner with the right to direct sale, transfer or withdrawal. The nominee arrangement does not remove the account from your FBAR, it is the very fact pattern the indirect financial interest rule was written to capture.
There is a second, separate hook worth knowing. Signature or other authority arises where an individual can control the disposition of money, funds or other assets held in a financial account by direct communication to the institution with which the account is maintained. Senior executives sometimes hold that authority over an employer-level plan funding account or an employee benefit trust bank account in the UK as part of their role. That is reportable on its own terms even where they own none of the money, and it is reported in the separate part of Form 114 for accounts over which the filer has signature authority but no financial interest.
How are Save As You Earn savings and share options treated?
Save As You Earn, or Sharesave, is the cleanest case and the one most often missed. GOV.UK describes the scheme at https://www.gov.uk/tax-employee-share-schemes/save-as-you-earn-saye and the headline terms are that you can save up to 500 pounds a month, and at the end of a savings contract of three or five years you can use the savings to buy shares. The interest and any bonus at the end of the scheme are tax free for UK purposes, and you do not pay UK Income Tax or National Insurance on the difference between what you pay for the shares and what they are worth. The savings themselves are not held by your employer. HMRC guidance on savings carriers at https://www.gov.uk/hmrc-internal-manuals/employee-tax-advantaged-share-scheme-user-manual/etassum34160 confirms that the linked savings arrangement is held with a bank, building society or European authorised institution.
That single fact resolves most of the analysis. A SAYE savings balance is money on deposit with a UK bank or building society in your name. It is a foreign bank account in the most conventional sense, indistinguishable in substance from a fixed-term savings account you opened yourself. It belongs on Form 114 as a bank account from the first year the aggregate threshold is crossed, and its maximum value climbs mechanically every month for three or five years until maturity. We have never seen a persuasive argument for leaving it off, and the UK tax-free treatment of the interest and bonus is irrelevant to the reporting question, because the FBAR is an information report rather than a tax computation.
The option itself is a different animal. An unexercised SAYE option is a contractual right to buy shares at a fixed price. It is not money or assets held in an account, nobody is maintaining an account balance for you in respect of it, and there is no statement value to report. The option does not go on the FBAR. What goes on the FBAR is the cash savings account that funds it, and then, once the option is exercised and shares are delivered, whatever account those shares land in.
How is a Share Incentive Plan account treated?
A Share Incentive Plan works differently because shares sit inside the plan rather than in your own name on the register. GOV.UK sets out the components at https://www.gov.uk/tax-employee-share-schemes/share-incentive-plans-sips and the components are that your employer can give you up to 3,600 pounds of free shares in a tax year, you can buy partnership shares out of pre-tax salary up to the lower of 1,800 pounds or 10 percent of your income for the tax year, your employer can give up to two matching shares for each partnership share you buy, and dividends on plan shares can be reinvested in dividend shares where the scheme allows it. Keep shares in the plan for five years and no UK Income Tax or National Insurance arises on their value, and keep dividend shares for at least three years and no UK Income Tax arises on them.
For FBAR purposes the plan account has both a cash and a share component, and both matter. The cash component is the accumulated salary deduction held between payroll date and the monthly share purchase, plus cash dividends held pending reinvestment and any residual cash from fractional entitlements. The share component is the free, partnership, matching and dividend shares held within the plan for your benefit. Because a UK institution holds those assets on your behalf and you can direct their disposal on withdrawal, the position we take on the returns we prepare is that the SIP account is reported, with the maximum value combining cash and the value of the shares held. The five-year UK holding rule affects the UK tax outcome and does nothing to the US reporting obligation.
Do unvested awards count toward the account balance?
Published FBAR guidance does not address equity compensation awards by name, so this has to be reasoned from the definition rather than quoted from a page. The FBAR reports the maximum value of an account, and the value of an account is what appears on the statements the institution issues for it. An unvested restricted share unit, an unexercised option and a SIP free share still inside its holding period before any risk of forfeiture has lapsed all share the same feature: they are contingent entitlements that can be lost, and nothing has been credited to an account you are able to direct. On that reasoning, an unvested award is not part of the maximum account value, and the balance you report is built from vested shares and cash actually held for you.
Two practical cautions follow. First, the moment of vesting is the moment the analysis changes, and share plan statements do not always distinguish clearly between vested and unvested holdings, so the split has to be requested from the administrator rather than eyeballed from a portfolio total. Second, the FBAR conclusion is not the Form 8938 conclusion. The IRS confirms at https://www.irs.gov/businesses/corporations/basic-questions-and-answers-on-form-8938 that an interest in a foreign pension or deferred compensation plan is reportable on Form 8938 where the thresholds are met, valued at the fair market value of your beneficial interest on the last day of the year. Where a UK award is genuinely deferred compensation rather than a plain unvested option, that separate analysis has to be run on its own terms and documented.
How do you determine the maximum account value where shares are held?
The maximum value is the largest amount of currency and non-monetary assets appearing on any quarterly or more frequent account statement issued for the year in question. Share plan administrators are the worst offenders for statement frequency. Many issue a single annual statement, some issue nothing at all unless you log in, and some issue a transaction confirmation only when shares move. Where quarterly or more frequent statements do not exist, the value has to be built from the records that do exist, and the objective is a reasonable, documented, contemporaneous figure rather than a guess made in April.
- The annual plan statement showing units and cash held, with the valuation date it uses.
- Payroll records showing the monthly deduction and the date it was applied to the plan.
- Vesting, maturity and exercise confirmations showing the number of shares delivered and the delivery date.
- Dividend confirmations showing cash received into the plan account and any reinvestment.
- Sale contract notes showing gross proceeds, costs and the date net cash left the plan account.
- A closing price for the employer share on the date of the highest holding, taken from the exchange on which the shares are listed.
Currency conversion trips people up because it does not follow the peak. The convention for the FBAR is to convert using the official exchange rate in effect at the end of the year at issue, published by the Treasury, rather than the rate on the day the balance peaked. So a sterling balance that peaked in June is converted at the December rate, which can move a borderline account either side of the threshold for reasons that have nothing to do with the account. Where you use an exchange rate, record which published rate you used and the date, because a valuation you cannot reconstruct three years later is a valuation you will end up re-doing.
What about shares registered directly in your own name?
This is the distinction that gets lost, and it cuts in the taxpayer's favour. Once shares leave the plan and are registered on the company register in your own name, whether as a certificated holding or a personal entry on the register, there is generally no financial account. Nothing is being maintained with an institution for you, there is no balance an institution is holding, and there is no account number to report. Directly registered shares are therefore generally outside the FBAR. The moment they are moved into a UK share dealing account, an ISA, or any nominee or broker service, an account exists again and the FBAR analysis restarts.
Form 8938 does not follow that logic. The IRS states at https://www.irs.gov/businesses/corporations/basic-questions-and-answers-on-form-8938 that where you hold foreign stock or securities outside a financial account, they must be reported on Form 8938 as separate line items, whereas assets held inside a reported financial account are not separately itemised because the account itself is reported. So the same block of employer shares can be off the FBAR entirely and squarely on Form 8938, purely because of where it is held. Note also that the 8938 category is foreign stock, so a directly held position in a US-incorporated employer is not caught by that line even though the plan account holding it might have been.
Where does Form 8938 fit alongside the FBAR?
Form 8938 is the FATCA report of specified foreign financial assets and it runs on completely different thresholds. Per https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements, a specified individual living in the United States files where the total value of specified foreign financial assets is more than 50,000 dollars on the last day of the year or more than 75,000 dollars at any time during the year, doubled to 100,000 and 150,000 dollars for a joint return. Living abroad, the figures rise to more than 200,000 dollars at year end or 300,000 dollars at any time for a single filer, and 400,000 and 600,000 dollars respectively on a joint return. Form 8938 is attached to the income tax return, while the FBAR is filed separately with FinCEN.
Filing one does not discharge the other. The IRS is explicit at https://www.irs.gov/businesses/corporations/summary-of-fatca-reporting-for-us-taxpayers that Form 8938 does not relieve filers of FBAR filing requirements, and the same page sets out the exposure for getting 8938 wrong: a 10,000 dollar failure to file penalty, an additional penalty of up to 50,000 dollars for continued failure after notification, and a 40 percent penalty on an understatement of tax attributable to non-disclosed assets. FBAR violations carry their own civil monetary penalties, with a far higher ceiling where conduct is willful, and the statutory amounts are inflation adjusted. Two forms, two thresholds, two penalty regimes, one underlying share plan account.
Why does a vesting or maturity event spike a single year?
The timing trap is the part that turns a technical omission into a real problem. Share plan balances do not grow smoothly. They creep for years and then jump in the single year a scheme matures, options are exercised, or a long-dated award vests and settles, and that is the year the maximum value is set. Here is an illustration, with figures chosen to show the mechanics rather than drawn from any client file.
Assume an executive saves the full 500 pounds a month into a five-year SAYE contract, so contributions total 30,000 pounds over 60 months before any bonus. For illustration only, assume a rate of 1.30 dollars to the pound, and note that the rate you must actually use is the published Treasury rate in effect at the end of the relevant year. In year one the savings balance reaches around 6,000 pounds, about 7,800 dollars, which alone is under the threshold, but added to a UK current account holding 5,000 pounds the aggregate is roughly 14,300 dollars, so an FBAR is due and the SAYE account should be on it. By year four the savings alone are around 24,000 pounds, roughly 31,200 dollars. Then year five arrives. The contract matures, the option is exercised, and shares worth 120,000 pounds are delivered into the plan nominee account before being sold and the proceeds paid across. If the plan account records both the matured savings and the delivered shares, the maximum value for the year is in the region of 150,000 pounds, about 195,000 dollars at the assumed rate.
Three consequences follow from that single year. The FBAR aggregate is now far above the threshold and the omitted account is no longer a rounding error. The Form 8938 test is comfortably breached for a US resident filer, because more than 75,000 dollars of specified foreign financial assets was held at some point during the year. And because the executive had been filing FBARs all along listing only the current account, the reports for the earlier years are not merely late, they are incomplete, which is a different and slightly awkward correction. The account that felt like it had nothing in it for four years determines the exposure across all of them.
How do you catch up missed FBAR years?
The route depends entirely on whether income was also unreported. If your US returns are correct, the SAYE interest, plan dividends and any disposal gains were all picked up, and the only defect is the missing or incomplete Form 114, the fix is mechanical. You file the late reports electronically through FinCEN's BSA E-Filing System at https://bsaefiling.fincen.gov, choosing a reason for filing late from the dropdown and giving a short factual explanation in the box. The IRS position at https://www.irs.gov/businesses/small-businesses-self-employed/report-of-foreign-bank-and-financial-accounts-fbar is to file late FBARs as soon as possible to keep potential penalties to a minimum. One point to be alert to: the IRS withdrew its standalone delinquent FBAR submission procedures page, so do not rely on a named IRS programme for this. The mechanism is the late-filing reason within the BSA E-Filing System itself, or a streamlined submission.
- Establish the six most recent years for which the FBAR due date has passed, and get the plan administrator to confirm account numbers, institution details and year-by-year maximum values in writing.
- Decide, year by year, whether the year needs an original late report or an amended report because a report was filed but the plan account was left off it.
- Check whether the underlying income was reported: SAYE interest and bonus, plan dividends, and any gain on disposal of plan shares.
- If income was omitted, stop and assess streamlined eligibility before filing anything piecemeal, because filing quietly first can close options.
- File through the BSA E-Filing System with a consistent, factual late-filing explanation across all years.
- Retain the filing confirmations and the supporting valuation file for at least five years.
Where income was also missed, the Streamlined Filing Compliance Procedures at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures are the usual route, and they require certification that the failure was due to non-willful conduct, meaning conduct due to negligence, inadvertence or mistake. If you meet the non-residency requirement, the Streamlined Foreign Offshore Procedures at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-outside-the-united-states apply. For a US citizen or lawful permanent resident that means, in one or more of the most recent three years, having no US abode and being physically outside the United States for at least 330 full days. The submission is delinquent or amended returns for the most recent three years for which the due date has passed, delinquent FBARs for the most recent six years, and a signed Form 14653. Filers who qualify are not subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties or FBAR penalties.
If you live in the United States, the Streamlined Domestic Offshore Procedures at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-in-the-united-states apply instead. Those require amended returns for the most recent three years, delinquent FBARs for the most recent six years, a signed Form 14654, and a Title 26 miscellaneous offshore penalty of 5 percent of the highest aggregate balance or value of the foreign financial assets, computed by aggregating year-end balances and values for each year in the covered period and taking the highest year. Under either track the FBARs are filed electronically through the BSA E-Filing System, selecting Other as the reason for late filing and entering Streamlined Filing Compliance Procedures in the explanation box. That wording matters, because it is how the submission is matched to the programme.
What records should you keep, and for how long?
The FBAR carries a standalone recordkeeping obligation that survives the filing. For each reportable account you must keep the name on the account, the account number, the name and address of the foreign institution, the type of account and the maximum value during the year, and the IRS requires those records to be retained for five years from the FBAR due date. For share plan accounts we build a single valuation file per year holding the annual plan statement, the vesting or maturity confirmation, the dividend and sale confirmations, the closing share price used and the exchange rate applied, with a short note explaining how the maximum value was derived and how vested and unvested holdings were split. That file is what makes a position defensible years later, and it is what converts a reconstruction exercise into a five-minute check.
The compliance checklist we run for UK share plan participants
- Ask the administrator directly where the account is maintained, rather than inferring it from the brand on the statement.
- Report the SAYE savings balance as a bank account from the first year the aggregate threshold is crossed, not from the year the shares arrive.
- Report the plan or nominee account holding vested shares and plan cash, and get vested and unvested holdings split in writing.
- Leave unexercised options and unvested awards out of the account maximum value, and record the reasoning in the file.
- Treat directly registered shares as outside the FBAR but run the separate Form 8938 analysis on them.
- Diarise the maturity or vesting year in advance, because that is the year both the FBAR and Form 8938 thresholds move.
- Convert at the published year-end Treasury rate, not the rate on the day of the peak balance, and record the rate used.
- Where an earlier FBAR was filed but the plan account was omitted, correct it by amended report rather than leaving the original standing.
The underlying point is simple enough to state and easy to miss in practice. The FBAR does not ask whether you have a foreign bank account. It asks whether a financial account is maintained outside the United States in which you have a financial interest, and a UK share plan administrator holding cash and vested shares through a nominee for a senior executive answers that question in the affirmative far more often than the executive expects. Because the balances are large and the omission is systematic rather than one-off, the correction is almost always cleaner and cheaper made proactively than after a plan administrator's own reporting brings the account to the attention of the US authorities.
