The IRS Streamlined Foreign Offshore Procedure is the route a US person living in the UK uses to correct years of unfiled or incomplete US tax returns without penalty, and a UK Enterprise Management Incentive (EMI) share option is one of the most common items that forces the issue. EMI options are tax-advantaged in the United Kingdom, but the United States does not recognise that favourable treatment. For a US citizen or green card holder working for a UK company, the grant, exercise and sale of EMI shares are taxed under ordinary US rules, and the income those events generate is frequently the reason a Streamlined catch-up becomes necessary at all. This article explains how EMI options flow through a Streamlined Foreign Offshore submission, where the US and UK results diverge, and what the certification on Form 14653 actually asks you to confirm.
What is the IRS Streamlined Foreign Offshore Procedure?
The Streamlined Foreign Offshore Procedures are one of two tracks within the IRS Streamlined Filing Compliance Procedures, described at https://www.irs.gov/individuals/international-taxpayers/streamlined-filing-compliance-procedures. They exist for taxpayers whose failure to file returns, report income or file foreign account reports was non-willful, meaning conduct that results from negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. The foreign track is for people who meet a non-residency requirement; a separate domestic track exists for US residents and carries a miscellaneous offshore penalty. The foreign track does not.
The mechanics are set out at https://www.irs.gov/individuals/international-taxpayers/us-taxpayers-residing-outside-the-united-states. A qualifying taxpayer files delinquent or amended returns for the most recent three years for which the due date has passed, together with any required information returns, and files delinquent foreign bank account reports (FinCEN Form 114, the FBAR) for the most recent six years. Full tax and interest are paid with the filing. The IRS states that a taxpayer who is eligible and who follows the instructions will not be subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. For a US person in the UK, that penalty relief is the central reason to use this route rather than simply filing forward.
The non-residency test matters. For US citizens and green card holders, the IRS requires that, in at least one of the three covered years, the person had no US abode and was physically outside the United States for at least 330 full days. A US person who has lived and worked in London for several years normally satisfies this comfortably. Note that the older Delinquent FBAR Submission Procedures that practitioners once relied on as a standalone named route are no longer presented by the IRS as a live option; late FBARs are now filed through FinCEN's BSA E-Filing System with a late-filing reason, or inside the Streamlined Filing Compliance Procedures. For anyone with unreported UK equity income, the Streamlined Foreign Offshore track is almost always the cleaner path.
Why does a UK EMI option create a US tax problem at all?
An EMI option is a UK-specific, HMRC-approved share option designed to let smaller trading companies reward key employees. The UK advantages are real and are summarised on GOV.UK at https://www.gov.uk/tax-employee-share-schemes/enterprise-management-incentives-emis. The headline point is that you pay no UK Income Tax or National Insurance if you acquire the shares for at least the market value they had when the option was granted, and a Capital Gains Tax charge is instead deferred to the eventual sale. In other words, in the UK a correctly structured EMI exercise is usually a non-event for income tax, and the tax arrives only when you sell.
The United States does not recognise EMI status. The favourable UK characterisation is a feature of UK domestic law, and nothing in US law imports it. For US federal tax purposes, an EMI option is treated as a nonqualified (nonstatutory) stock option. It is not a US incentive stock option, because incentive stock option status depends on a US-qualifying plan and a list of Internal Revenue Code conditions that an EMI scheme does not meet. The consequence is that each stage of the option's life is tested against the ordinary US rules, and those rules produce income at a different time and of a different character than the UK rules do.
This divergence is why EMI appears so often in Streamlined cases. A UK-based US person reasonably sees a scheme their employer describes as tax-free at exercise, their UK payroll withholds nothing, and they conclude there is nothing to report. The US return tells a different story, and the gap typically surfaces only when the shares are sold, when an accountant reviews the position, or when the company goes through a funding round or sale and the equity history is examined.
How does the US tax an EMI option at grant, exercise and sale?
Because an EMI option is a nonqualified option for US purposes, the timing generally runs as follows. At grant, a nonqualified option over private company shares usually has no readily ascertainable fair market value, so there is ordinarily no US income event on the grant itself. That lines up with the UK, where grant at market value is not taxed. The two systems part company at exercise.
On exercise, US rules under Section 83 of the Internal Revenue Code generally treat the spread, meaning the fair market value of the shares at exercise minus the exercise price paid, as ordinary compensation income in the year of exercise. The UK, by contrast, imposes no income tax at that moment on a qualifying EMI exercise. So a US person can have a substantial slug of US ordinary income in a year in which their UK tax position shows nothing. If the shares received on exercise are themselves subject to a substantial risk of forfeiture, the Section 83 timing shifts and a Section 83(b) election can become relevant, which is a separate decision with its own 30-day deadline.
On sale, the US treats the disposal as a capital event, measuring gain against a basis equal to the exercise price plus any amount already taxed as ordinary income at exercise. The UK applies Capital Gains Tax to its own measure of the gain. The two gains are rarely identical, because the US figure is computed in dollars from a dollar basis while the UK figure is computed in sterling, and exchange rate movement across a multi-year hold alone can drive them apart. The following sequence captures the usual pattern for a US person holding EMI options in the UK:
- Grant: no US income event and no UK income tax, assuming the option is granted at market value
- Vesting: generally no standalone US charge on a vanilla option, unless shares are received early and are forfeitable
- Exercise: US ordinary income on the spread under Section 83, while the UK charges no income tax on a qualifying EMI exercise
- Sale: US capital gain or loss measured from a stepped-up basis, and a separate UK Capital Gains Tax computation in sterling
Does exercising an EMI option trigger US alternative minimum tax?
This is a frequent point of confusion, because US employees are often warned that exercising an incentive stock option creates an alternative minimum tax preference. That warning does not translate directly to EMI. Since an EMI option is a nonqualified option for US purposes, exercising it does not create the incentive stock option alternative minimum tax preference item. Instead, the spread is ordinary income in the regular tax computation in the year of exercise, as described above.
That does not mean the alternative minimum tax can be ignored. A year with a large equity event, foreign tax credits, and multiple adjustments is exactly the kind of year in which the alternative minimum tax interacts with the regular tax in unexpected ways, so the position should be computed rather than assumed away. The practical point for a Streamlined submission is narrower: the exercise-year ordinary income is the figure most likely to have been omitted, and it is the figure that must be picked up on the amended or delinquent return for that year.
What about the shares themselves: PFIC and Form 5471?
Once the option is exercised, the US person owns shares in a foreign corporation, and two information-reporting regimes can switch on. The first is the passive foreign investment company, or PFIC, regime. A foreign corporation is a PFIC if it fails either an income test or an asset test weighted towards passive income and assets. EMI can only be offered by companies carrying on a qualifying trade, so an active operating business is usually not a PFIC. The risk is not zero, however: an early-stage company sitting on a large cash pile from a funding round can fail the asset test in a given year, and the tests are mechanical and must be run rather than presumed. If the company is a PFIC, the shareholder faces the punitive PFIC rules and Form 8621, which is one of the information returns that would accompany the relevant Streamlined years.
The second regime is Form 5471, the information return for US persons with interests in foreign corporations. A small option position is well below the thresholds, but exercising options and accumulating shares can push a US employee across the ownership lines that bring Form 5471 into play, particularly founders and senior staff whose holdings grow over successive rounds. The categories of filer, the attribution rules and the overlap between them are detailed, and a filer who meets more than one category does not file multiple times for the same facts. Form 5471 carries heavy penalties for omission, which is precisely why it is one of the required information returns that a Streamlined Foreign Offshore submission is designed to bring up to date.
How do EMI options surface inside the IRS Streamlined Foreign Offshore Procedure?
In a Streamlined Foreign Offshore submission, the EMI history is not reported as a single line. It is spread across the three years of income tax returns, the six years of FBARs, and the certification. On the income side, the exercise-year ordinary income belongs on the Form 1040 for the year of exercise, and if that year falls inside the three-year window it is corrected there. Where the exercise predates the three covered years, the income itself may sit outside the window, but the resulting share ownership, and any dividends or sale proceeds since, still have to be reported correctly in the covered years.
On the account side, an unexercised option is not itself a foreign financial account, and shares held directly in your own name on a company register are not an FBAR account either. But shares and cash held through a foreign brokerage, nominee or custodial account are reportable, and those accounts must appear on the six years of FBARs. Many EMI participants hold their post-exercise shares through exactly such an arrangement without realising it is an account for FBAR purposes. The specified foreign financial asset rules behind Form 8938 can also pull the holding onto the income tax return where the thresholds are met.
- Three years of returns: pick up any exercise-year ordinary income and any dividend or sale income in the covered years
- Required information returns: attach Form 8938, Form 8621 or Form 5471 for the covered years where the facts require them
- Six years of FBARs: report any foreign brokerage, nominee or custodial account holding the shares or sale proceeds
- Form 14653: certify eligibility, that all required FBARs are now filed, and that the conduct was non-willful
A worked example of an EMI exercise in a Streamlined catch-up
The following figures are illustrative only and are chosen to show the mechanics, not to state any threshold or rate. Suppose a US citizen who has lived in London for six years was granted EMI options in year one over 10,000 shares with an exercise price of 1 pound per share, equal to the market value at grant. In year four she exercised when the shares were worth 9 pounds each. For UK purposes, the qualifying EMI exercise produced no income tax charge. For US purposes, the spread of 8 pounds per share, roughly 80,000 pounds converted to dollars at the exercise-date rate, was ordinary compensation income on her year-four Form 1040. She did not report it, because her UK payroll showed nothing and she assumed the scheme was tax-free.
In year six she sells the shares for 15 pounds each. For US purposes her basis is the exercise price plus the spread already taxable at exercise, so the taxable gain is measured from 9 pounds, not from 1 pound; the UK computes its own Capital Gains Tax on the sterling gain. When she comes to file a Streamlined Foreign Offshore submission covering her three most recent years, the omitted exercise income from year four is corrected if that year is in the window, the brokerage account holding the shares goes onto six years of FBARs, and the sale is reported with a basis that reflects the US income already recognised. Her Form 14653 narrative explains, truthfully, that she believed the UK tax-advantaged status settled the US position too. That is a classic non-willful fact pattern, but it has to be set out honestly and supported by the documents.
What does the Form 14653 certification actually require?
Form 14653, the Certification by U.S. Person Residing Outside of the United States for Streamlined Foreign Offshore Procedures, is the document that ties the submission together, and it is signed under penalties of perjury. On it, the taxpayer certifies that they are eligible for the procedures, that all required FBARs have now been filed, and that the failure to report income, pay tax and file the required returns and FBARs resulted from non-willful conduct. The IRS defines that as conduct due to negligence, inadvertence, mistake, or a good-faith misunderstanding of the law.
The narrative portion is not a formality. It must give the specific reasons for the non-compliance, covering the taxpayer's personal and financial background, and an EMI case needs to explain plainly why the equity income went unreported. A statement that the employer described the scheme as tax-free, that UK payroll withheld nothing, and that the taxpayer did not understand the separate US treatment is often accurate and persuasive, but it must be the real story. Overstating reliance on an adviser who was never consulted, or glossing over a point the taxpayer did in fact understand, is the sort of thing that turns a non-willful narrative into a willful problem. Preparation discipline, not advocacy, is what carries the certification.
How is double taxation relieved, and where does it break down?
Because the UK taxes the EMI gain at sale while the US taxes part of the same economic value as ordinary income at exercise, relief from double taxation depends on matching the two systems in time and in character. The main US mechanism is the foreign tax credit, claimed by individuals on Form 1116, Foreign Tax Credit, described at https://www.irs.gov/individuals/international-taxpayers/foreign-tax-credit. In principle, UK tax paid on the equity can be credited against US tax on the same income, subject to the sourcing, basketing and limitation rules.
The break point is timing. The US income arises at exercise; the UK income tax charge on a qualifying EMI is nil at exercise, and the UK instead charges Capital Gains Tax at sale. If the US recognises ordinary income in year four and the UK recognises a capital gain in year six, there may be little or no UK tax in year four to credit against the US charge, and the credit machinery does not always reach across years cleanly. Carryback and carryforward rules can rescue part of the position, and the sourcing of the compensation element matters, but the mismatch is structural rather than a filing error. A Streamlined submission that recognises the income correctly is the starting point; optimising the credit across the affected years is a separate piece of preparation.
What should a US person with EMI options do before filing?
The groundwork for a clean Streamlined Foreign Offshore submission is mostly documentary, and it is worth assembling before any return is drafted. The aim is to reconstruct the equity history precisely enough that the income, the accounts and the certification all tell the same, verifiable story.
- Gather the EMI option agreement, grant notices, the agreed market value at grant and the exercise paperwork
- Establish the share value and exchange rate at the date of exercise, since the spread is a US income figure
- Identify every foreign account that held the options proceeds, shares or dividends for the six FBAR years
- Test the company for PFIC status in each relevant year and check whether Form 5471 or Form 8938 is required
- Confirm the non-residency requirement is met for the covered years before relying on the foreign track
- Draft the Form 14653 narrative from the real facts, and keep the evidence that supports every statement in it
Tax rules, filing thresholds, forms and procedures change, and the Streamlined Filing Compliance Procedures themselves have been revised over time and could be withdrawn or altered. Nothing here is a substitute for checking the current position directly on IRS.gov and GOV.UK and taking preparation and compliance support from someone competent in both systems at once. The recurring failure in EMI cases is not a sophisticated error; it is a UK-advantaged scheme assumed to be US-advantaged, discovered late. The IRS Streamlined Foreign Offshore Procedure exists precisely to fix that, without penalty, for the US person who acts before the IRS does.
