The phone call always sounds the same. A senior banker, in their late thirties or early forties, calls from a City office between meetings to explain that something within the firm has flagged a US tax issue. Sometimes it’s an internal mobility review. Sometimes it’s a routine FATCA form circulated by HR. Sometimes it’s a payroll question about a deferred award that no one can answer cleanly. By the time the conversation reaches us, the banker already knows they’ve missed several years of US returns. What they don’t know is whether the solution will cost them a hundred thousand pounds or several million, and whether the next twelve months will involve a quiet catch-up or an open IRS examination. Specialist IRS Streamlined Filing Experts exist precisely for this conversation, because banker compensation disrupts ordinary expat tax workflows in ways that require real subject-matter knowledge.
This guide explains how the Streamlined Foreign Offshore Procedures actually work for someone with banker-style pay, what gets missed when generalist advisers try to handle these cases, and what a clean submission looks like from first call to filing.
IRS Streamlined Filing Experts are cross-border tax advisers who specialize in Streamlined Filing Compliance Procedure submissions for US persons living outside the United States. The procedure itself is an IRS program that allows non-wilful taxpayers to file three years of federal returns and six years of FBARs without the standard civil penalty regime applying. Qualifying foreign-resident filers see the failure-to-file, failure-to-pay, accuracy-related, information return, and FBAR penalties waived in full. The formal rules are available on the IRS website at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures.
The label “expert” matters because the gap between a competent Streamlined submission and a banker-grade Streamlined submission is wide. Anyone qualified can file three years of returns and six FBARs. Far fewer advisers can correctly handle a portfolio of deferred bonus awards across overlapping vesting tranches, time-apportioned RSUs that straddle US and UK working periods, characterize carried interest in a side-pocket investment fund, identify FBAR-reportable accounts where the banker holds signing rights but no beneficial ownership, and draft a Form 14653 narrative credible enough to survive examination of a financially literate taxpayer. That gap is what makes specialist advice worth paying for.
Banking compliance has tightened on three fronts this year. FATCA reporting from UK and international banks has reached the point where the IRS sees almost every account a US-citizen banker holds before any conversation about disclosure happens. UK banks, US brokerages, Swiss private banks, and the in-house custody platforms used by major firms all share account data under the relevant intergovernmental agreements, including the https://www.gov.uk/government/publications/uk-us-automatic-exchange-of-information-agreement. The data is already with the IRS by the time the banker walks into an adviser’s office.
Internal compliance within banks has also moved up a gear. Bulge-bracket and boutique firms in London now run periodic US tax compliance reviews on their American staff. The driver is partly self-protection, because firms with non-compliant US-person employees face their own FATCA exposure. The practical effect is that HR or the internal mobility team often surfaces the gap before the IRS does, which gives the banker a narrow window to file Streamlined before any formal notification closes the door.
IRS enforcement priorities point in the same direction. The agency has publicly committed to multi-year funding for enforcement against high-income individuals and complex compensation structures, and bankers sit squarely within that population. The wilful FBAR penalty regime, capped at the greater of $129,210 (the 2024 inflation-adjusted figure) or 50% of the account balance per violation per year, makes the cost of waiting for IRS contact disproportionately large for anyone with seven-figure account balances.
Deferred bonus structures sit at the center of every banker’s streamlined submission. A standard London banker bonus splits into a current-year cash payment and a deferred portion that vests over three to five years, often in restricted stock, notional units linked to firm performance, or deferred cash subject to forfeiture clauses. UK tax usually bites at the vest. US tax can bite earlier or later, depending on whether the plan is subject to IRC §409A, whether there is a substantial risk of forfeiture, and how the underlying instrument is characterized. Reconstructing this picture across three field years for a banker carrying multiple rolling deferral tranches from different bonus cycles is the single most demanding part of the work, and getting it wrong creates exactly the kind of inconsistency examiners look for.
Restricted stock units granted by a US parent and vested while the banker is UK-resident are among the most common foreign tax credit failures in cross-border banking work. The UK taxes the vest on a time-apportioned basis if the grant period covered any US working time. The US taxes the vest in full, with a foreign tax credit available for UK tax paid on the same income. When the apportionment isn’t modeled correctly, the banker either pays tax twice on a portion of the vest or wastes credit that can’t be carried forward to a useful purpose. Specialist IRS Streamlined Filing Experts model the apportionment day by day across the grant period, match the UK and US numbers, and document the credit position so the submission holds together if examined.
Bankers regularly hold signing rights over accounts they don’t personally own. Trading book accounts, fund accounts at firms where they sit on investment committees, escrow accounts opened for deal closings, and trustee or protector accounts on family structures all carry FBAR reporting obligations under https://www.fincen.gov/report-foreign-bank-and-financial-accounts. The IRS treats signature authority and beneficial ownership identically for FBAR purposes. Bankers routinely miss these accounts in initial inventories. They don’t consider them “their” accounts, and examiners specifically look for these omissions because they’re so often missed.
Pull the full compensation history. Before any numbers are entered, gather every grant letter, every annual bonus letter, every RSU vesting schedule, every deferred award document, every long-term incentive plan summary, and every payslip for the look-back period. The deferred compensation analysis cannot be done without these documents, and the foreign tax credit calculation has nowhere to anchor without them.
Inventory every account, including signing rights. List personal current accounts, savings accounts, ISAs, SIPPs, US brokerage accounts opened in earlier life and forgotten, joint accounts with a spouse, family-related accounts, and every firm-level account where the banker holds signature authority. Pull the highest balance per account per year across the six FBAR look-back years.
Run the wilfulness analysis under privilege. Bankers occupy a different position from ordinary expats on the question of wilfulness because their profession requires financial sophistication. The Form 14653 narrative will be read on that assumption. Where the facts sit close to the wilful line, US tax counsel should run the analysis under attorney-client privilege before Streamlined is chosen. Wilful conduct routes to the IRS Voluntary Disclosure Practice, as set out in its https://www.irs.gov/compliance/criminal-investigation/irs-criminal-investigation-voluntary-disclosure-practice
Reconstruct three years of returns with each income line characterized properly. Base salary, current-year cash bonus, RSU vest values, dividend equivalents on unvested units, deferred award taxable events, partnership distributions on side investments, US-source dividends from any legacy brokerage account, and UK rental or investment income each carry their own sourcing rule and credit treatment.
Coordinate with the firm where confidentiality allows. Most major banks run internal mobility tax teams that can confirm plan characterizations and provide vesting data in a clean format. Where the banker is comfortable looping the firm in, coordination produces cleaner numbers. Where confidentiality matters, the work happens independently using the banker’s own grant letters and payslips.
Write the Form 14653 narrative as a serious document. A two-paragraph certification stating “the taxpayer did not understand US obligations” will not withstand scrutiny when the taxpayer earns seven figures in the financial services industry. The narrative needs dates, facts, and an honest explanation consistent with the documentary record. For most bankers, the truth is defensible, but it needs to be properly documented.
A US citizen managing director at a European investment bank came to us last autumn after an internal compliance review flagged the gap. She had moved to London from a New York analyst seat in 2017, promoted to MD by 2023, and had filed her last US return in 2017 on the assumption that her UK tax position covered everything that mattered. Total compensation across the eight unfiled years sat well into eight figures: base salary, an annual cash bonus, three overlapping tranches of deferred equity, cash awards, an LTIP that paid out in 2022, and a personal portfolio she had built alongside her firm holdings. Her accounts included Coutts (current and investment), HSBC (joint with her UK-born husband), a legacy JP Morgan US brokerage account from her business school years, a Hargreaves Lansdown SIPP, and signing rights over a fund vehicle in which she sat on the investment committee.
The wilfulness analysis ran first, under privilege with US tax counsel. Her facts supported Streamlined cleanly: she had filed correctly while resident in the US, her gap was tied to a specific (and common) misunderstanding about citizenship-based taxation, and there was no evidence of asset concealment. We then reconstructed three years of US returns, capturing salary, current-year cash bonus, RSU vesting with day-by-day time apportionment between US and UK working periods, dividend equivalents on unvested units, deferred cash awards taxable under §409A in the three filing years, and investment income on her personal portfolio. The foreign tax credit on UK income tax cleared most of the US liability on UK working compensation.
Two pieces took the longest. The deferred award characterization required reading the firm’s plan documents in detail to confirm §409A treatment and to determine the correct US taxable event for each tranche. The legacy JP Morgan brokerage account had generated US-source dividends throughout the eight unfiled years, creating a residual US tax liability that the UK foreign tax credit couldn’t offset. We filed six FBARs covering every account, including the fund vehicle for which she held signing rights, and the Form 14653 narrative ran to three pages, explaining her arrival in London, the bonus cycles that reinforced the misunderstanding, and the internal review that triggered the compliance work.
Total cash cost, including back tax, interest, and our fees, came in under £180,000. Penalty exposure for the unreported accounts alone under the wilful FBAR regime would have exceeded $9 million across the six-year look-back window.
Treating deferred compensation as a future-year issue. Some bankers assume the US tax on deferred awards only matters in the year the award pays out. A US taxable event under §409A and related provisions can occur earlier than the UK vest, and missed reporting in that earlier year is exactly what the Streamlined submission needs to address.
Ignoring the legacy US brokerage account. Bankers who opened US brokerage accounts during business school or as analysts often leave them running long after they relocate. Those accounts generate US-source income that flows into both UK worldwide income reporting and the US return. Leaving them out of the Streamlined submission breaks the entire compliance position.
Claiming the RSU foreign tax credit without proper apportionment. Time apportionment between US and UK working periods is fact-specific and document-dependent. Bankers who claim the foreign tax credit on the full UK tax paid without modeling the working-day split usually end up either double-taxed or with the IRS questioning the credit position during a later examination.
Missing accounts with signing rights. Investment committee members, deal-team signatories, and family-vehicle trustees all hold FBAR reporting obligations on accounts they don’t beneficially own. Examiners look for these omissions specifically because they’re the most reliable indicator that the FBAR work wasn’t done seriously.
Choosing Streamlined when the conduct was wilful. Bankers who previously filed US returns and then deliberately stopped, or who moved assets to non-reporting jurisdictions, face a different question from ordinary non-filers. Using Streamlined for a genuinely wilful case can convert a difficult civil matter into a criminal one, and should not be attempted without prior privileged legal analysis.
Submitting a thin Form 14653 narrative. A boilerplate certification will not survive examination by a banker. The narrative needs to be specific about dates, working history, when US obligations were first understood, and what triggered the compliance work. Examiners read these documents on the assumption that the taxpayer is financially literate.

For investment bankers in London who have fallen behind on US filings, specialist IRS Streamlined Filing Experts are the difference between a clean catch-up and a submission that unravels on later examination. The Streamlined Foreign Offshore Procedures waive the punitive penalty regime for qualifying non-wilful taxpayers, but the complexity of compensation in banking means the standard mechanics need careful overlay. Deferred bonus pools, RSU vesting across jurisdictions, signing rights over firm and fund accounts, and legacy US brokerage holdings all need their own analysis inside the submission. Bankers who act before an internal HR query or an IRS contact letter retain control of the timing, the cost, and the narrative that the IRS will read.
Yes. US citizens and green card holders must file an annual federal return, regardless of where they live, if their income exceeds the standard filing threshold. For bankers, the threshold is crossed in the first week of any normal year. FBAR filing with FinCEN is also required if foreign account balances exceed $10,000 in aggregate at any point during the year, which applies to almost every London-based banker holding personal and firm-related accounts.
Deferred bonuses are taxed under US rules when the deferral becomes taxable under IRC §409A and related provisions, which is often earlier than the UK vest. The Streamlined submission needs to capture the US taxable event in the correct year, with foreign tax credit treatment matched to UK tax paid at vest. Plan documents must be carefully read to identify the correct US characterization, which is one of the main reasons specialist advice matters for banker submissions.
RSUs are reported in the year of vest, with the fair market value at vest included in US taxable income. Where the vesting period covers both US and UK working time, the income is apportioned for foreign tax credit purposes based on the number of working days in each jurisdiction. Dividend equivalents paid on unvested units are also taxable. The submission must capture each vest event in the correct year with apportionment supporting the credit claim.
The Streamlined submission goes to the IRS, not to the bank, and the IRS does not notify employers of taxpayer filings. UK banks already report US account holders to the IRS under FATCA regardless of Streamlined status. The firm typically becomes aware of its compliance status only through its internal HR review, which operates independently of any filings the banker makes.
