EIS, SEIS and VCTs: Why US Citizens Should Think Twice

The UK's venture capital reliefs cut a UK tax bill, but the IRS recognises none of them. What an EIS, SEIS or VCT investment really costs a US citizen once foreign tax credits, PFIC rules and US capital gains tax are counted.

SEIS and EIS money flows into early-stage UK companies like this one, but a US citizen investor gets none of the UK reliefs back on the US return.

For an EIS SEIS US citizen investor, the UK reliefs are real but the US ignores them: the Income Tax relief shrinks the foreign tax credit you would have used against US tax, the UK-exempt gain is fully taxable in the US, and VCTs are likely PFICs. The net benefit is usually far smaller than the brochure suggests.

The Enterprise Investment Scheme (EIS), the Seed Enterprise Investment Scheme (SEIS) and Venture Capital Trusts (VCTs) are among the most generous reliefs in the UK tax code. UK advisers recommend them to higher earners every spring. For a US citizen or green card holder living in the UK, the same advice can backfire, because the US taxes worldwide income and has no matching relief. This guide sets out what each scheme gives you in the UK for 2026/27, what the IRS does with it, and how to decide whether the investment still makes sense.

What do EIS, SEIS and VCTs offer UK taxpayers in 2026/27?

EIS, SEIS and VCTs give an upfront Income Tax reduction plus Capital Gains Tax advantages, in return for investing in small, higher-risk UK companies and holding the shares for a minimum period. The figures below come from the GOV.UK guidance on venture capital schemes tax relief for investors, last updated on 6 April 2026.

SchemeIncome Tax reliefAnnual investment limitMinimum holdingUK CGT treatment
SEIS50%£200,0003 yearsGain on the shares exempt; 50% of the investment can exempt other gains, up to £100,000
EIS30%£1 million (£2 million if at least £1 million goes into knowledge-intensive companies)3 yearsGain on the shares exempt; other gains can be deferred in full
VCT20%£200,0005 yearsGains exempt, including on second-hand shares; dividends free of Income Tax

The VCT figure is new. GOV.UK records that the percentage of a VCT investment on which relief can be claimed was updated on 6 April 2026, and the rate it now shows is 20%, down from the 30% that applied before. EIS and SEIS rates are unchanged.

Three further UK rules matter for planning. Relief cannot be carried forward: GOV.UK says unused relief is lost. EIS and SEIS relief can be claimed in the year of investment or carried back to the previous tax year, while VCT relief is limited to the year of investment. And for EIS and SEIS you must not be connected with the company, which broadly means not holding more than 30% of it and not being a paid employee, with limited exceptions for directors.

Does the US recognise EIS or SEIS relief for a US citizen?

No. The US recognises neither EIS, SEIS nor VCT relief. A US citizen or green card holder files a Form 1040 reporting worldwide income and gains, and the US computes its tax under US law alone. A UK relief changes how much UK tax you pay; it does not change your US taxable income by a single dollar.

The US/UK tax treaty does not fill the gap either. Under the treaty's saving clause the US keeps the right to tax its own citizens as if the treaty did not exist, apart from a short list of exceptions, and venture capital reliefs are not on that list. Our guide to the saving clause in the US/UK tax treaty explains how far that reaches.

So the question for an American is never "how much relief do I get?" It is "how much relief survives once the US return is done?" That depends on how the UK relief interacts with the foreign tax credit.

How EIS and SEIS relief shrinks your foreign tax credit

The foreign tax credit is the main way an American in the UK avoids paying full tax twice. You pay UK Income Tax on your salary, then claim that UK tax as a credit against the US tax on the same salary. Because UK rates are usually higher than US rates on employment income, many Americans in the UK end up owing little or no US tax on their pay.

EIS, SEIS and VCT relief reduces the UK Income Tax you actually pay. The IRS says the foreign tax that qualifies for the credit is only the legal and actual foreign tax liability you paid or accrued, reduced by any refund. When EIS relief brings your UK bill down by £30,000, your creditable UK tax falls by the same £30,000.

What happens next depends on how much headroom you had:

  • Large excess credits. If your UK tax was well above the US tax on the same income, the relief mostly uses up credits you could not have used anyway. The UK saving largely survives.
  • Little or no excess. If your UK tax only just covered the US tax, the relief leaves a gap, and the US collects tax on that gap. Part of the UK saving moves straight to the IRS.
  • Carryovers. Unused foreign tax credits from earlier years can sometimes absorb the gap, which is why the answer depends on your full credit history and not just one year.

Our guide to the foreign tax credit and UK tax relief shows how the credit limit is calculated, and the IRS foreign tax credit page covers the categories of income the credit is sorted into.

A clawback adds another layer

If you sell EIS or SEIS shares inside the minimum period, or the company stops qualifying, HMRC can withdraw the relief. You then pay the UK tax after all. For US purposes, that later UK tax may relate back to the earlier year, which can mean amending the US return to restore the credit. That is paperwork a UK-only investor never sees.

The UK-exempt gain is fully taxable in the US

The headline EIS and SEIS benefit is a gain free of UK Capital Gains Tax after three years. For a US citizen it is not tax-free. The gain is reported on Schedule D of the US return in dollars, and because the UK charged nothing, there is no UK tax to credit against it. The full US tax is a real cost.

The IRS guidance on capital gains and losses treats shares held for more than one year as long-term, so a three-year EIS holding normally qualifies for long-term capital gains rates. The gain is measured in dollars, using the exchange rate when you bought and when you sold, so currency movement alone can create a US gain or loss that does not exist in sterling. Our post on UK Capital Gains Tax for US citizens covers those currency gains in more detail.

Deferral and reinvestment relief do not cross the Atlantic

EIS deferral relief lets a UK investor reinvest a gain from any asset into EIS shares and postpone the UK tax. SEIS reinvestment relief goes further and exempts part of the gain. Neither exists in US law. The original gain is taxed on the US return in the year you made it, whatever you did with the proceeds. A US citizen who sells a property or a share portfolio and reinvests into EIS still pays US tax on that gain straight away, and has no UK tax that year to credit against it.

Losses are worth less in the US

Startups fail, and the UK softens that with loss relief: GOV.UK says an EIS loss, less the Income Tax relief already given, can be set against income of the year of sale or the year before. The US is far less generous. The IRS limits net capital losses set against other income to $3,000 a year ($1,500 if married filing separately), with the rest carried forward to later years. A large EIS write-off can take many years to use on the US side.

Is a VCT a PFIC for a US citizen?

A Venture Capital Trust is very likely to be a PFIC for a US shareholder. The Instructions for Form 8621 define a passive foreign investment company as a foreign corporation where 75% or more of gross income is passive, or at least 50% of its assets produce passive income. A VCT is a UK investment company that earns dividends, interest and gains on the shares it holds, which is exactly the income the test catches.

PFIC status brings three problems. Under the excess distribution rules, a distribution above 125% of the average of the previous three years is spread over every day of the holding period: the share for the current year is ordinary income, and the share for earlier PFIC years carries a separate tax and interest charge under section 1291(c). Form 8621 is generally required for each PFIC each year. And the tax-free VCT dividend becomes US taxable income with no UK tax to credit.

The elections that soften the rules are hard to use here. A qualified electing fund (QEF) election requires the company to give shareholders a PFIC Annual Information Statement, which UK VCTs rarely produce for US investors. A mark-to-market election is only available for marketable stock that is regularly traded on a qualifying exchange; listed VCT shares may qualify, but the market for them is thin, and a mark-to-market election taxes paper gains each year as ordinary income. Our pages on the PFIC definition and the excess distribution rules walk through the mechanics.

Can an EIS or SEIS company be a PFIC?

Sometimes. An EIS or SEIS company is usually a trading business, which normally keeps it outside the PFIC rules. But a startup that has just raised money may hold mostly cash for a year or more, and cash is a passive asset under the asset test. Interest on that cash is passive income. The answer has to be tested each year from the company's accounts, and a US investor should ask the company for the figures before investing.

US reporting for EIS, SEIS and VCT shares

Holding shares in a UK company brings US information returns even when no tax is due:

  1. Form 8938. The IRS comparison of Form 8938 and FBAR requirements lists foreign stock held directly, outside a financial account, as reportable on Form 8938. For taxpayers living abroad the threshold is more than $200,000 on the last day of the year or $300,000 at any time (single or married filing separately), or $400,000 and $600,000 for married couples filing jointly.
  2. FBAR. Shares held directly are not an FBAR item. Shares held through a nominee, platform or managed EIS portfolio may sit in a custody account, and that account can be reportable. See our guide to FBAR vs Form 8938.
  3. Form 8621. Required for each PFIC, including most VCTs and any EIS or SEIS company that meets the PFIC tests in a given year.
  4. Form 5471. Larger stakes in a UK company, or controlling stakes held with other US persons, can trigger this return; SEIS and EIS founders and angel syndicates should check it.

EIS vs SEIS vs VCT for a US citizen: which survives best?

US loss treatmentCapital loss, $3,000 a year limitCapital loss, $3,000 a year limitPFIC rules complicate losses

Broadly, a direct SEIS or EIS investment in a genuine trading company is the least bad option for an American, because the PFIC risk is lower and the relief rate is higher. A VCT combines a lower UK relief with near-certain PFIC treatment, which makes it the hardest to justify for most US taxpayers.

What people get wrong

  • Treating the UK relief as the return. A 30% relief is only worth 30% to an American with surplus foreign tax credits. With no surplus, much of it becomes US tax.
  • Forgetting the deferred gain. Reinvesting a gain into EIS defers UK tax only. The US taxes that gain in the year it was made.
  • Assuming a UK-listed company is just a share. VCTs are investment companies, and investment companies are where the PFIC rules bite.
  • Leaving the UK mid-holding. GOV.UK says deferred EIS gains come back into charge if you become non-resident, while the US keeps taxing you as a citizen wherever you live.

An illustrative example

Illustrative example: a US citizen in London pays UK Income Tax on a high salary and invests £100,000 in an EIS company in 2026/27, claiming 30% relief, £30,000 off her UK bill. Before the investment her UK tax only slightly exceeded the US tax on her salary, so after the relief her creditable UK tax falls below the US tax, and she owes the IRS part of the difference. Four years later she sells the shares for £250,000. The £150,000 gain is free of UK Capital Gains Tax, but on her US return the gain is measured in dollars and taxed at long-term capital gains rates, with no UK tax to credit. Her net benefit from EIS is a fraction of the £30,000 headline. The figures are invented to show the mechanics, not a forecast of anyone's tax.

How to decide, step by step

  1. Work out your foreign tax credit position for the year: how far your UK tax exceeds the US tax on the same income, and any credit carryovers.
  2. Model the relief as reduced creditable UK tax, not as free money, and see how much US tax it creates.
  3. Ask the company or fund manager for figures that let you test PFIC status, and assume a VCT is a PFIC unless shown otherwise.
  4. Price in the US tax on any eventual gain, and the slower US use of any loss.
  5. Check how the shares will be held, so you know whether Form 8938, the FBAR or both apply.

If the numbers still work, the investment can be worthwhile, especially SEIS and EIS in a trading company you believe in. If they do not, a US-friendly alternative may suit better.

Frequently asked questions

Can a US citizen claim EIS or SEIS relief in the UK?

Yes. EIS and SEIS relief depends on paying UK Income Tax and meeting the scheme conditions, not on nationality, so a US citizen who is a UK taxpayer can claim it. The problem is on the US side. The IRS does not recognise either relief, and the UK tax you save reduces the foreign tax credit you could otherwise use against US tax on the same income.

Is an EIS gain tax-free for a US citizen?

No. A gain on EIS shares held for at least three years can be exempt from UK Capital Gains Tax, but the US taxes its citizens on worldwide gains and does not follow the UK exemption. The gain is reported on Schedule D in dollars, at long-term rates if the shares were held more than one year. Because no UK tax was paid on it, there is no foreign tax credit to offset the US tax.

Is a Venture Capital Trust a PFIC?

A Venture Capital Trust is very likely to be a PFIC for a US shareholder. A VCT is a UK investment company whose income is mostly dividends, interest and gains on shares, which is passive income under the PFIC income test. A US citizen holding VCT shares should expect to file Form 8621 and to face the excess distribution rules unless an election is available and made in time.

Are VCT dividends taxable in the US?

Yes. GOV.UK says dividends from a VCT are exempt from UK Income Tax, but a US citizen reports them on the US return. If the VCT is a PFIC, a distribution above 125% of the average of the previous three years is an excess distribution taxed under the PFIC rules. Smaller distributions are ordinary income, and there is no UK tax on them to claim as a credit.

Can an SEIS company be a PFIC?

It can. A foreign corporation is a PFIC if 75% or more of its gross income is passive or at least 50% of its assets produce passive income. A newly funded startup can hold mostly cash for a year or more, and cash counts as a passive asset. Whether a particular SEIS or EIS company is a PFIC has to be tested year by year from its accounts.

Do EIS shares go on the FBAR or Form 8938?

The IRS comparison table says foreign stock held directly, outside a financial account, is reported on Form 8938 but not on the FBAR. EIS or SEIS shares held in your own name therefore count towards the Form 8938 thresholds. Shares held through a nominee or a managed EIS portfolio may sit in a custody account, which can bring that account onto the FBAR.

What happens to EIS relief if a US citizen leaves the UK?

GOV.UK says deferred EIS Capital Gains Tax becomes payable if you become non-resident during the holding period, and Income Tax relief can be withdrawn if the conditions stop being met. The US side does not change when you move, because the US taxes its citizens wherever they live. Plan the timing of a move with both countries in view.
