Can I use the Streamlined Foreign Offshore Procedures if I have never filed a US return?

Yes. The procedures accept delinquent returns as well as amended ones. A US citizen or green-card holder who meets the non-residency test, including 330 full days outside the United States in at least one of the last three years, and whose failures were non-wilful, files three years of returns, six years of FBARs and Form 14653, and pays the tax and interest due.

Is there a penalty under the Streamlined Foreign Offshore route?

No. The IRS states that a taxpayer who complies with the foreign offshore instructions is not subject to failure-to-file, failure-to-pay, accuracy-related, information return or FBAR penalties. You pay the tax and statutory interest only. Penalties already assessed for those years are not removed, and the protection does not hold if a later examination finds fraud or wilfulness.

Do I report UK start-up shares on the FBAR or on Form 8938?

Shares held directly in your own name are reported on Form 8938, once your total specified foreign financial assets exceed the threshold for taxpayers abroad, and are not reported on the FBAR. Shares held for you by a nominee through an account, and any platform cash balance, need assessing for the FBAR, which applies when foreign accounts exceed $10,000 in aggregate.

Is every UK start-up a PFIC for US tax purposes?

No. A company is a PFIC only if 75% or more of its gross income is passive, or at least 50% of its assets on average produce or are held to produce passive income. Trading companies with revenue normally fail both tests. The risk sits with cash-rich, pre-revenue companies, and the answer comes from each company's accounts, year by year.

Does HMRC's EIS or SEIS relief count on my US tax return?

No. EIS and SEIS Income Tax relief and the Capital Gains Tax exemption on disposal are UK reliefs claimed through Self Assessment using the company's compliance certificate. The United States taxes the gain in full, and because an exempt gain bears no UK tax, there is no foreign tax credit to set against the US liability on that exit.

Do I need Form 5471 if I own less than 10% of a UK company?

Generally not as a shareholder, because the filing categories for investors turn on holding 10% or more of the vote or value. The exception is a director or officer: Category 2 can apply where any US person has acquired 10% of the company. Check each year separately, since a stake can pass through 10% before later rounds dilute it.

Streamlined Foreign Offshore: US Angels in UK Start-Ups

The IRS Streamlined Foreign Offshore Procedure (SFOP), which the IRS itself titles the Streamlined Foreign Offshore Procedures, lets a US citizen or green-card holder settled in the UK who has non-wilfully missed US returns and FBARs come back into compliance by filing three years of returns and six years of FBARs with no penalty, and a portfolio of UK start-up stakes does not stop you using it. What the portfolio changes is the size of the file. Each holding has to be tested for Form 8938, for passive foreign investment company status, for Form 5471 and for the FBAR, and every exit, write-off and interest payment in the three-year window has to be on the return.

This guide is written for investors with real money spread across early-stage UK companies: direct ordinary shares, convertible loan notes, advance subscription agreements and positions held through a syndicate or nominee. We prepare these submissions as a tax preparation and compliance exercise, and the pattern is consistent. The investor has usually been meticulous on the UK side, with relief certificates filed and Self Assessment up to date, and has either never filed in the US or has filed for years without the investments appearing anywhere.

What is the Streamlined Foreign Offshore procedure and who qualifies?

The Streamlined Foreign Offshore Procedures are the IRS route for US taxpayers living outside the United States whose failure to report foreign financial assets, pay the tax due on them and file FBARs was non-wilful. The IRS sets out the terms at https://www.irs.gov/individuals/international-taxpayers/u-s-taxpayers-residing-outside-the-united-states and the page is short enough to read in full before you start.

Two conditions carry most of the weight. The first is non-residency. A US citizen or lawful permanent resident meets it if, in at least one of the most recent three years for which the return due date has passed, they did not have a US abode and were physically outside the United States for at least 330 full days. An investor who has lived in London for a decade normally meets this comfortably, but frequent US business travel should be counted from passport stamps and travel records, not estimated. The second is non-wilful conduct, which the IRS describes as conduct due to negligence, inadvertence or mistake, or conduct that results from a good faith misunderstanding of the requirements of the law.

The package itself has four parts:

Delinquent or amended US income tax returns for each of the most recent three years for which the due date has passed, together with every required information return, such as Forms 5471 and 8938.
Delinquent FBARs (FinCEN Form 114) for each of the most recent six years for which the FBAR due date has passed, filed electronically through FinCEN's BSA E-Filing System.
A signed original Form 14653, Certification by US Person Residing Outside of the US, certifying eligibility, that all required FBARs have been filed, and that the failures were non-wilful.
Payment of the full tax shown on the returns plus statutory interest.

The IRS states that a taxpayer who complies with these instructions will not be subject to failure-to-file and failure-to-pay penalties, accuracy-related penalties, information return penalties or FBAR penalties. There is no percentage-of-assets charge under the foreign offshore route; that feature belongs to the separate domestic procedure for US residents. The protection is not unconditional. Previously assessed penalties are not removed, and the IRS reserves the position where a later examination finds fraud or wilfulness.

The returns go on paper to the Austin address given on the IRS page, not through e-file, with the wording the IRS specifies written in red at the top of each return. A missing or deficient Form 14653 means the returns are processed in the ordinary way, without the penalty protection. The general eligibility conditions for all streamlined submissions also apply, so anyone who has already heard from the IRS about an examination should establish their position before preparing anything.

Why do angel portfolios make a streamlined submission harder?

An angel investor has eight, fifteen or thirty separate legal relationships, each with its own cap table, instrument type and history of funding rounds. US reporting asks a different question of each company, and the answer can change from year to year as rounds dilute you, as a company's cash position moves, or as a loan note converts.

The failure mode we see most often is a return prepared on the assumption that small unquoted stakes are invisible to the US system because they pay no dividends and sit outside any brokerage account. They are not. For each holding, four tests need running:

Form 8938: is the holding a specified foreign financial asset, and does the total cross the threshold for a taxpayer living abroad?
PFIC: did the company meet the passive income test or the passive asset test in any year you held it?
Form 5471: did you reach 10% of the company, or serve as an officer or director when a US person did?
FBAR: is the position held directly in your own name, or through an account that someone holds on your behalf?

Do directly held UK start-up shares go on Form 8938?

Yes, where the threshold is met. The IRS comparison table at https://www.irs.gov/businesses/comparison-of-form-8938-and-fbar-requirements confirms that foreign stock or securities not held in a financial account are reportable on Form 8938, and that the same directly held stock is not reportable on the FBAR. This is the most common gap in the returns we review for investors who had been filing: bank accounts on the FBAR, salary on the return, and the share certificates nowhere.

For taxpayers living abroad, the same IRS page gives the thresholds. A single filer, or a married person filing separately, must file when the total value of specified foreign financial assets is more than $200,000 on the last day of the tax year or more than $300,000 at any time during the year. For a married couple filing jointly the figures are $400,000 and $600,000. Form 8938 is attached to the income tax return, which is why it travels with the three streamlined returns and not with the FBARs.

The practical difficulty is valuation. Unquoted shares have no screen price, so a reasonable estimate has to be built and documented, usually from the price of the most recent funding round, adjusted where a company has plainly deteriorated. Loan notes and advance subscription agreements need the same attention. They are claims against a foreign company and should be assessed for Form 8938 alongside the shares, not left out because no share certificate has been issued yet. The IRS page puts the penalty for failing to disclose at up to $10,000, with further amounts after IRS notice, which is one of the exposures the streamlined terms remove.

When is a UK start-up a passive foreign investment company?

A passive foreign investment company, or PFIC, is a foreign corporation that meets either of two tests for its tax year. Under the income test, 75% or more of its gross income is passive income. Under the asset test, at least 50% of the average percentage of its assets produce passive income or are held to produce it. Both tests are set out in the Form 8621 instructions at https://www.irs.gov/instructions/i8621 and neither contains any carve-out for a company simply because it is a genuine operating business.

That is why early-stage companies are exposed. A pre-revenue company that has just closed a funding round may hold little except cash, and its only income may be bank interest. Cash is generally treated as a passive asset for this purpose, so a cash-rich company with no revenue can meet one or both tests in exactly the years when an angel is most likely to invest. Once trading revenue and operating assets build up, the company typically falls outside the definition, but the earlier years remain part of your holding period.

The statute does contain a start-up year exception. Under section 1298(b)(2), which can be read at https://www.law.cornell.edu/uscode/text/26/1298 a corporation is not treated as a PFIC for the first taxable year in which it has gross income if three conditions are met: no predecessor was a PFIC, it is established to the satisfaction of the Secretary that it will not be a PFIC in either of the two following years, and it is in fact not a PFIC in either of those years. The exception is narrower than it sounds. It covers one year, it is measured from the first year with gross income, and it fails retrospectively if the company is still cash-heavy and pre-revenue in year two or three. For a company that raises seed money and takes three years to reach meaningful sales, it often does not help.

Where a holding is a PFIC, Form 8621 comes into the return. The instructions require a separate Form 8621 for each PFIC, and the default treatment taxes gains and certain larger distributions under the excess distribution rules, with part of the amount allocated back over the holding period and subject to an interest charge. Elections exist, including the qualified electing fund election, but that election depends on information the company has to supply, and most UK start-ups have never been asked for it. The instructions also provide a limited exception from the annual Part I reporting where the total value of all PFIC stock is $25,000 or less at year end, or $50,000 on a joint return, and there has been no excess distribution or gain.

Whether a particular company was a PFIC in a particular year is a factual question answered from its accounts, not from its sector. In a streamlined file, we request the statutory accounts for each company for each year of ownership and record the result company by company. Convertible instruments need separate thought, because the same section treats an option to acquire stock as ownership of that stock under regulations, so an unconverted right is not automatically outside the regime.

When does a minority angel stake trigger Form 5471?

Usually it does not, and that should be said plainly. Form 5471 is built around a 10% ownership threshold, and a typical angel cheque buys a low single-digit percentage. The categories are defined in the instructions at https://www.irs.gov/instructions/i5471 and three of them are the ones an investor can fall into without controlling anything.

Category 3 applies to a US person who acquires stock that takes them to the 10% threshold, or who acquires a further 10% or more. A lead investor in a first seed round can cross 10% briefly before later rounds dilute the stake, and the filing obligation arises for the year of acquisition even if the percentage is back under 10% eighteen months later. Category 2 applies to a US citizen or resident who is an officer or director of a foreign corporation in which a US person has made such an acquisition. Angels who take a board seat should note that the test looks at whether any US person crossed the threshold, not only the director personally. Category 5 applies to a US shareholder, meaning a US person holding 10% or more of the vote or value, of a controlled foreign corporation, which is a foreign corporation more than 50% owned by such US shareholders. A syndicate dominated by American investors can produce that result in a company none of them thinks of as American.

Control in the Category 4 sense is unusual for an angel, but where a filer meets both Category 4 and Category 5a, the current form has them check Category 4 only. The instructions state a $10,000 penalty for each annual accounting period of each foreign corporation for failure to file, which again is covered by the streamlined penalty terms when the form is included in the package. There is also an interaction worth knowing: the Form 8621 instructions describe an overlap rule under which a US shareholder of a controlled foreign corporation that is also a PFIC is generally not subject to the PFIC provisions for that stock during the qualified portion of the holding period. A 10% holder and a 2% holder in the same company can therefore be on entirely different forms.

Are nominee and platform holdings reportable on the FBAR?

Share certificates in your own name are not FBAR items. Accounts are. The FBAR is required when the aggregate value of foreign financial accounts exceeds $10,000 at any time in the calendar year, and the regulation at https://www.law.cornell.edu/cfr/text/31/1010.350 defines both what an account is and when you have a financial interest in one. A securities account is an account with a person engaged in the business of buying, selling, holding or trading stock or other securities. A US person has a financial interest in an account where they are the owner of record or hold legal title, and also where the owner of record is a person acting as an agent, nominee, attorney or in some other capacity on their behalf.

That second limb is what catches investors who use online investment platforms and syndicates. Where shares are registered in the name of a nominee company and you see only a dashboard entry, the question is whether that arrangement is an account maintained with a business that holds securities for clients. In many platform structures we look at, it is, and in almost all of them there is also a client cash balance holding uninvested funds or exit proceeds awaiting withdrawal. Both need assessing for each of the six FBAR years. The answer depends on the platform's legal terms, so we read the nominee agreement, not the marketing page.

How are exits, write-offs and loan-note interest reported?

A sale of start-up shares is a capital disposal for US purposes and is reported on Form 8949 and Schedule D, unless the company was a PFIC, in which case Form 8621 governs the gain. The US computation is done in dollars: the cost is translated at the rate when you invested and the proceeds at the rate when you sold, so the US gain will not match the sterling gain on your UK computation, and currency movement over a six- or seven-year hold can move the figure materially in either direction.

Failures matter as much as successes in an angel portfolio. The US rules allow a loss when a security becomes wholly worthless, and the difficult part is the year: the loss belongs to the year the shares actually became worthless, which is a question of evidence such as an insolvency appointment, a dissolution or a formal cessation of trade. Because a streamlined submission covers only three years of returns, a company that failed before the window opened does not produce a loss inside it. We establish the timeline for every failed holding before deciding what the returns can properly show.

Income during the holding period is usually modest. Dividends from early-stage companies are rare, and where one is paid it goes on the return like any other foreign dividend, with separate treatment if the payer is a PFIC. Loan-note interest is the item most often missed. Interest on a convertible loan note is ordinary income for US purposes, and notes that roll up interest and convert it into shares still need reviewing for the years in which that interest is treated as arising, since no cash arrives to prompt the question. Advance subscription agreements carry no interest, but the date on which they convert sets the start of the holding period and the cost of the resulting shares, so the conversion paperwork belongs in the file.

Do EIS and SEIS reliefs reduce US tax?

No. The Enterprise Investment Scheme and Seed Enterprise Investment Scheme are UK reliefs and have no US equivalent. HMRC's investor guidance at https://www.gov.uk/guidance/venture-capital-schemes-tax-relief-for-investors sets out Income Tax relief of 30% of the amount invested under EIS and 50% under SEIS, a minimum holding period of at least three years, and no Capital Gains Tax on a disposal of the shares where the Income Tax relief has not been reduced or withdrawn. Relief is claimed using the compliance certificate issued by the company, through Self Assessment or a tax code adjustment.

None of that enters the US computation, and two consequences follow. A gain that is exempt in the UK is still a taxable capital gain on the US return, and because no UK tax was paid on it there is no foreign tax to credit against the US liability. Separately, the UK Income Tax relief lowers your UK tax bill in the year of investment, which reduces the pool of UK tax available to offset US tax on your other income. Investors who assumed that being fully taxed in the UK left nothing to pay in the US are often right for a salary and wrong for an exempt exit.

What does a streamlined file look like for an investor with eight holdings?

The following is an illustration only. The figures are assumed for the example and are not drawn from any client. Take a US citizen, single, living in London since 2014, employed in finance and never a US filer. She spends fewer than three weeks a year in the United States and has no US home. Her portfolio is assumed to be worth roughly $450,000 in dollar terms at each year end, spread across eight positions.

Holdings 1 to 3: ordinary shares held in her own name in three trading companies, each under 3%, all subscribed under EIS. One was sold at a gain inside the three-year window; one went into liquidation inside the window.
Holding 4: a 12% stake taken in a founding SEIS round, with a board seat, later diluted below 10%.
Holding 5: a convertible loan note with rolled-up interest, not yet converted.
Holding 6: an advance subscription agreement that converted into shares during the window.
Holdings 7 and 8: two positions held through a syndicate, registered in the name of a platform nominee, with a client cash balance on the same platform.

Non-residency is met on the 330-day test for all three years. Form 8938 is required in each year because the assumed value exceeds the $200,000 year-end threshold for a single filer abroad, and every position is listed with a documented value. PFIC testing is run on all eight companies from their filed accounts; assume two were cash-rich and pre-revenue in their first two years, fail the start-up year exception and need a Form 8621 each. Holding 4 needs Form 5471 analysis for the year she reached 10% and for her period as a director. Holdings 7 and 8 and the platform cash balance go on six years of FBARs with her bank accounts, since the aggregate is well over $10,000.

The exit on holding 1 is exempt from UK Capital Gains Tax under EIS, so the US gain, recomputed in dollars, carries US tax with no UK credit against it. The liquidation produces a US capital loss in the year the shares became worthless. Rolled-up interest on holding 5 is reviewed for each year. Form 14653 then tells the story honestly: UK-compliant throughout, unaware that citizenship alone created a US filing obligation, and no steps taken to conceal anything. The result is three returns with a substantial stack of attachments, six FBARs, tax and interest on the exit, and no penalties.

What records should you gather before starting?

The preparation time on these files is driven by documents, not by the forms. For each company we ask for the subscription agreement or loan note instrument, the share certificate or nominee statement, the cap table position after each round, statutory accounts for each year of ownership, any EIS3 or SEIS3 certificate, and completion statements for any sale or liquidation distribution. For the platform, we ask for the nominee terms and annual statements showing cash balances. A travel log for the three return years supports the non-residency test.

Late FBARs outside a streamlined submission are filed through FinCEN's BSA E-Filing System with a reason for late filing, and that route offers none of the certainty described above for the income tax side. For an investor whose omissions include unreported gains or interest, the streamlined package is the route designed for the facts. Our role is the preparation: testing each holding, assembling the returns, information returns and FBARs, and making sure the certification is supported by the record.
