Do the UK EIS tax reliefs reduce my US tax bill?

No. The 30% income tax relief and the capital gains exemption are features of UK law, and US law does not recognise them. The United States taxes your worldwide income and gains under its own rules, so an EIS gain that is tax-free in Britain is still taxable in America. A foreign tax credit only helps where you actually paid UK tax, and an exempt EIS gain produces none to credit.

Is a directly held EIS shareholding reportable on the FBAR?

Not by itself. The FBAR reports foreign financial accounts, and shares registered in your own name on the company's register are not an account. If instead you hold the EIS shares through a UK platform, broker or fund nominee account, that account is FBAR-reportable once your aggregate foreign accounts exceed 10,000 dollars at any time in the year.

Are my EIS shares a PFIC?

Usually not, if you hold direct shares in a genuine EIS-qualifying trading company, because an active trading business does not meet the passive income or asset tests. The answer is fact-specific, though. A pooled corporate EIS fund that simply holds a portfolio of shares can be a PFIC in its own right, and even a direct holding can raise the question in an early year when the company is sitting on uninvested cash.

I never filed Form 8938 for my EIS shares — what should I do now?

File amended returns adding the Form 8938 for each affected year, with a reasonable-cause statement explaining why it was missed. If all income was already reported there is no additional tax, and the exposure is information-return penalties that reasonable cause is meant to address. If income or a gain was also unreported, the Streamlined Foreign Offshore Procedures are usually the better route.

The UK made my EIS gain tax-free. Is it really taxable in the US?

Yes. The UK capital gains exemption has no effect on your US return. When you dispose of the shares, the United States taxes the gain under its own rules, normally at long-term capital gains rates if you held them over a year. Because there is no UK tax on the exempt gain, there is no foreign tax credit to offset the US charge, so the US tax is a genuine cost.

Can I use the Streamlined Foreign Offshore Procedures to fix a missed EIS holding?

Often, yes, if your failure to report was non-willful and you meet the non-residency test. You file three years of amended or delinquent returns and six years of FBARs with a certification of non-willfulness, and eligible filers avoid the usual penalties, paying only tax and interest. It is only available while the IRS has not yet contacted you, so the time to act is before any notice arrives.

Missed Reporting a UK EIS Holding to the IRS

Missed reporting an investment account is one of the quieter cross-border failures we see, and a UK Enterprise Investment Scheme holding is a textbook way for it to happen. A US citizen living in Britain is offered the chance to back a promising young UK company, puts in a few thousand pounds, claims 30% income tax relief on the UK side, and files the paperwork away feeling they have done everything by the book. They have — in Britain. What nobody tells them is that the United States taxes its citizens on worldwide income and assets wherever they live, and that the shares they now hold may have triggered one or more US reporting duties the moment the subscription was accepted. The EIS certificate that felt like a reward for sensible investing can quietly become a missed foreign-asset disclosure.

This article is about that specific gap: a US person who invested in an EIS and never reported it to the IRS. We will look at what EIS actually is, why its generous UK reliefs do nothing for you in America, which US forms were probably missed — Form 8938 above all, the FBAR in some fact patterns, and possibly Form 8621 — and how you unwind the problem now. The PFIC question in particular needs a careful, fact-specific answer, because the wrong assumption in either direction is costly. This is not about wills or family wealth structures; it is purely about an ordinary direct investment that slipped below the US radar.

What is the UK Enterprise Investment Scheme?

The Enterprise Investment Scheme is a UK government initiative designed to channel private money into small, higher-risk trading companies that would struggle to raise capital otherwise. In exchange for taking that risk, the investor collects a bundle of UK tax incentives. The headline relief is income tax relief worth 30% of the amount subscribed for new shares, set against the investor's UK income tax bill, subject to an annual limit and a minimum holding period. Hold the shares for at least three years and meet the conditions, and any gain on their eventual sale is exempt from UK capital gains tax. There is also deferral relief, which lets an investor postpone an existing capital gain by reinvesting it into EIS shares, and loss relief if the company fails — a real possibility given the kind of company EIS exists to fund.

Those reliefs are deliberately generous because the underlying investments are genuinely risky: EIS companies are, by design, young unquoted businesses carrying on a qualifying trade. For a UK-only taxpayer the arithmetic is attractive. For a US citizen in the UK, the very same investment sits inside a second tax system that neither recognises the reliefs nor cares that HMRC blessed them.

Do the UK's EIS reliefs count for anything on my US return?

In a word, no, and this is the first hard truth. UK tax reliefs are creatures of UK law, and US law does not adopt them. The 30% income tax relief reduced your UK income tax; it has no analogue in the US system and does not reduce your US liability on anything at all. The UK capital gains exemption on a qualifying EIS disposal is, from the IRS's point of view, simply absent — when you sell the shares at a profit, the United States taxes that gain under its own rules as though the UK exemption did not exist.

The point bites hardest on gains. The foreign tax credit can relieve US tax where you have actually paid UK tax on the same income, but an EIS disposal that is exempt in the UK generates no UK tax to credit. So the very feature that makes EIS attractive to a British investor — a tax-free exit — removes the mechanism that would otherwise shield a US investor from double taxation. You can end up paying full US capital gains tax on a gain that cost you nothing in Britain, which is the opposite of what the certificate seemed to promise.

Which US form was actually missed — is it Form 8938?

In most cases, yes: Form 8938 is the headline omission. Form 8938 is the FATCA disclosure of specified foreign financial assets, and shares in a foreign corporation fall squarely within that definition when they are held directly rather than inside a US brokerage account. EIS shares are shares in a UK company, so they are a specified foreign financial asset, and they belong on Form 8938 once your total such assets cross the reporting threshold.

The thresholds are higher for Americans who genuinely live abroad, which is a small mercy. A US person living outside the United States must file Form 8938 if their specified foreign financial assets exceeded 200,000 dollars on the last day of the year or 300,000 dollars at any point during it, with those figures doubling to 400,000 and 600,000 dollars for a married couple filing jointly. The EIS holding is not measured in isolation — it is aggregated with your UK pensions, investment accounts and other foreign financial assets, so a modest EIS subscription can be the item that tips an already-substantial portfolio over the line, or simply one more asset that should have appeared on a form you were already required to file.

Does an EIS holding go on the FBAR?

Sometimes, and the answer turns entirely on how you hold the shares. The FBAR, FinCEN Form 114, reports foreign financial accounts rather than assets as such, and it is required when the aggregate maximum value of your foreign accounts exceeds 10,000 dollars at any time in the year. A direct shareholding — shares registered in your own name on the company's register, with a paper or electronic certificate — is not an account, and on its own it does not go on an FBAR.

But EIS shares are very often not held that way. If you subscribed through an investment platform, an EIS fund manager's nominee arrangement, or a broker that holds the shares for you in a custody or dealing account, then you have a foreign financial account, and that account is FBAR-reportable once the threshold is met — reported at the account's maximum value, not the cost of the shares. Two investors with identical EIS holdings can therefore have different FBAR outcomes purely because of the plumbing: one holds certificates directly and has nothing to add for the shares, the other holds them through a UK nominee account and does. This is exactly the sort of distinction that gets missed.

Is my EIS investment a PFIC?

This is the question that demands the most care on EIS cases, because the answer is genuinely fact-specific and the stakes are high. A passive foreign investment company, or PFIC, is a foreign corporation that meets either an income test — 75% or more of its gross income is passive — or an asset test — 50% or more of its assets produce, or are held to produce, passive income. If a holding is a PFIC it is reported on Form 8621 and, absent a timely election, taxed under the punitive excess-distribution rules of section 1291, which back-load tax and an interest charge onto gains and certain distributions in a way that can consume much of the return.

Here is the reassuring part. Direct shares in an EIS-qualifying operating company are generally not a PFIC, and the reason is structural. EIS relief is only available where the company carries on a genuine qualifying trade — an active business, not an investment vehicle — so an operating EIS company is usually generating active trading income and holding its assets for that trade. A company that actually trades does not look like the passive-income corporation the PFIC rules were written to catch.

But generally is doing real work in that sentence, and three wrinkles deserve attention. First, timing: a brand-new company that has just raised a round of EIS money may be sitting on a large cash pile before it has deployed it, and cash is a passive asset, so in an early year even a genuine trading company can meet the asset test. The code contains a start-up exception for a company's first year with gross income, but it is narrow and does not rescue every early-stage scenario. Second, look-through rules treat a parent as holding its share of a 25%-or-more subsidiary's assets and income, which can shift the analysis for group structures. Third, and most important for investors, an EIS fund is not the same thing as an EIS company.

Many people invest through an EIS fund, and the US treatment depends on what that fund actually is. A large number of EIS funds are not companies at all — they are discretionary managed portfolios in which the manager uses your money to subscribe for shares in several underlying trading companies and holds them for you through a nominee. In that case you look through to each underlying company and run the PFIC analysis on each one, much as you would for a direct holding. If, however, the fund is itself a foreign corporation that holds a portfolio of shares — a pooled corporate vehicle — then the fund entity is very likely a PFIC in its own right, because an entity whose business is holding investments is the textbook passive company. You cannot answer the PFIC question from the marketing brochure; you have to know the legal structure.

How are EIS dividends and gains taxed on my US return?

EIS companies are growth businesses and rarely pay dividends, but when they do, the dividend is foreign-source income to a US person and is taxed as such, with a foreign tax credit available only for any UK tax actually suffered. More commonly the money event is the exit — a trade sale or an acquisition — and that is where the mismatch is sharpest. The gain the UK exempts after three years is fully taxable in the United States. If you have held the shares for more than a year it should qualify for long-term capital gains rates, which softens the blow, but there is no UK tax on the gain to credit against the US charge, so that US tax is a real, out-of-pocket cost.

If the holding turns out to be a PFIC and no qualifying election was made in time, the gain is not a clean long-term capital gain at all. Under the default section 1291 rules it becomes an excess distribution spread back over your holding period, taxed at the highest ordinary rate for each prior year with an interest charge layered on top. That is precisely why the PFIC determination matters so much, and why pretending the question does not exist is the costliest form of missed reporting.

A worked example: £50,000 into an EIS, UK relief versus the US position

Take Daniel, a US citizen who has lived in London for a decade. In 2021 he subscribed £50,000 for shares in a qualifying EIS technology company, held directly on the register in his own name. On his UK return he claimed income tax relief of 30%, worth £15,000 against his UK income tax, and he expected that holding the shares for the three-year minimum would make any eventual gain UK tax-free. These are illustrative figures, not a real client.

On the UK side, everything worked. In 2025 the company was acquired, and Daniel's shares were bought out for £120,000. Because he had met the EIS conditions, the entire £70,000 gain over his £50,000 subscription was exempt from UK capital gains tax, and he paid nothing to HMRC on the exit. In net terms, after the £15,000 of income tax relief, a £35,000 cash outlay had turned into £120,000 completely free of UK tax.

On the US side, none of that protection existed. As a US citizen, Daniel was required to report the shares on Form 8938 for every year from 2021 onward once his foreign assets crossed the threshold — which, with a UK pension already in the mix, they long had — yet he had never filed Form 8938 at all. The £120,000 exit was also a fully taxable disposal for US purposes: a gain of roughly £70,000, converted into dollars at the relevant exchange rates, taxable at US capital gains rates with no UK tax to credit because the UK had exempted it. The relief that saved him £15,000 in Britain bought him nothing in America, and the tax-free British exit produced a live US tax bill on top of years of missed disclosures.

Change one fact and it gets worse. Had Daniel invested through a pooled corporate EIS fund rather than a single trading company, each year of ownership could have required a Form 8621, and the exit could have fallen into the section 1291 excess-distribution regime instead of enjoying long-term capital gains treatment. Same £50,000, a very different US outcome, decided by the fund's legal structure.

Missed reporting an investment account: your US forms checklist

When a US investor realises an EIS holding was never reported, the first job is to map exactly which forms were in play. Missed reporting an investment account rarely involves a single form; it is usually a cluster, and the cluster depends on how the shares were held and what the underlying company was. Here is the checklist we run:

Form 8938 (Statement of Specified Foreign Financial Assets) — almost always in play, because directly held foreign shares are specified foreign financial assets once your worldwide foreign assets exceed the abroad thresholds of 200,000 or 300,000 dollars for single filers and 400,000 or 600,000 dollars for a joint return.
FBAR (FinCEN Form 114) — in play only if the shares are held through a foreign account, such as a platform, broker or fund nominee, and your aggregate foreign accounts exceeded 10,000 dollars at any point in the year. Not required for shares held directly on the company register.
Form 8621 (PFIC reporting) — in play if the holding is a PFIC: unlikely for direct shares in an active trading company, but a genuine risk for a pooled corporate EIS fund, and possible even for a direct holding in an early year dominated by cash. Fact-specific, so check the structure.
Form 1040 with Schedule B and Schedule D — any dividends must be reported on Schedule B, and a disposal goes on Schedule D and Form 8949 as a taxable capital gain regardless of the UK exemption.
Form 1116 (Foreign Tax Credit) — relevant only to the extent you actually paid UK tax; an EIS gain that is UK-exempt generates no credit to claim.

How do I catch up — amended returns or Streamlined Foreign Offshore?

The right remediation route depends on two things: whether you also under-reported income, and whether your failure to file was non-willful. If your US returns were otherwise correct and complete and you simply omitted Form 8938 or Form 8621 — the income was reported, or there was none to report — the fix is usually to file amended returns adding the missing forms, with a reasonable-cause statement explaining the omission. There is no income tax to make good in that scenario; the exposure is information-return penalties, which reasonable cause is designed to address.

Where the EIS holding also meant income or gains went unreported — an unreported dividend, or more often an unreported disposal — the Streamlined Foreign Offshore Procedures are usually the better home for US citizens resident in the UK. The streamlined route requires that your conduct was non-willful, that you meet the non-residency test (broadly, physically outside the US for at least 330 full days in at least one of the three years, with no US abode), and that you file amended or delinquent returns for the most recent three years and FBARs for the most recent six, together with a signed certification of non-willfulness. Eligible filers who complete it are relieved of failure-to-file, accuracy-related and information-return penalties, and of FBAR penalties, paying only the tax and interest actually due.

One caution on the FBAR side, if your shares were held through a reportable account. The IRS previously ran Delinquent FBAR Submission Procedures for people who had reported all their income but missed the FBAR; that route was withdrawn in mid-2026 and should not be relied on as a live, penalty-free option. Late FBARs should still be filed as soon as possible with an explanation, and where they sit alongside unreported income the streamlined procedures are the cleaner path. Both routes depend on the IRS not having contacted you first, which is why acting before any letter arrives is worth so much.

Putting a missed EIS holding right

Missed reporting an investment account is unsettling precisely because it tends to happen to careful people — the investor who did everything the UK asked and simply did not know a second tax system was watching. An EIS holding is a classic trigger: generous UK reliefs that mean nothing in America, a disposal that is tax-free in Britain and taxable in the States, and a PFIC question that has to be answered on the facts rather than assumed away. The reassuring news is that the problem is fixable, and it is almost always better to fix it on your own initiative than to wait for a letter.

The order of operations matters. Establish how the shares are held, determine whether the company or fund is a PFIC, quantify any US tax on dividends or the exit, and then choose the catch-up route that fits — amended returns with reasonable cause for a pure disclosure gap, or the Streamlined Foreign Offshore Procedures where income was also missed. Handled properly, a frightening-looking omission becomes a clean, well-documented filing, and the EIS investment goes back to being what it was meant to be: a bet on a young company, not a latent US compliance problem.
