Introduction: Why a Return of Capital From a UK Company Is Taxed Twice Over
A return of capital is a payment a UK company makes to its shareholders out of their own subscribed capital rather than out of profits, and for an American shareholder it is one of the most misunderstood events on a US tax return. In London, the label decides the answer. A properly executed capital reduction repays share capital, HMRC treats the cash as a capital receipt, and income tax does not apply. In Washington, however, the label means almost nothing. The Internal Revenue Code ignores what the company calls the payment and asks a single question: does the company have earnings and profits?
Consequently, the founders, investors, investment bankers and company owners we work with are regularly surprised to discover that a payment their British accountant described as a tax-free return of capital is a fully taxable dividend in the United States. The reverse also happens. A listed company can pay cash through a B share scheme that HMRC now taxes as income, while the IRS treats part of the same cash as a return of capital that simply reduces basis. In both cases the two tax systems describe the same pound in different ways, and the foreign tax credit struggles to bridge the gap.
At TaxYork, we prepare US and UK returns for American shareholders in British companies, from owner-managed trading groups to FTSE holdings. This guide explains how a UK company returns capital, how HMRC taxes it, how the IRS taxes it under section 301, where the mismatches arise, and how to report the event correctly, including what to do if earlier returns got it wrong.
How a UK Company Makes a Return of Capital
A UK company can hand capital back to shareholders in several ways. Most commonly, it reduces its share capital or cancels its share premium account and pays the released amount out in cash. Alternatively, it can buy back or redeem shares, make a capital distribution in a members' voluntary liquidation, or, for larger listed companies, issue a special class of B shares that are then redeemed or paid out. Each route produces a return of capital in the commercial sense, yet each carries a different tax analysis on both sides of the Atlantic.
This article concentrates on the first and last routes: capital reductions and B share schemes. Share buybacks raise their own redemption tests, which we cover in our guide to UK share buybacks for American owners. Similarly, distributions in a solvent winding up follow separate liquidation rules, set out in our guide to a members' voluntary liquidation for American shareholders.
Why High-Net-Worth Shareholders Meet This Problem
In practice, a return of capital usually follows a liquidity event. A trading company sells a division and holds more cash than it needs. A holding company receives sale proceeds from a subsidiary. A venture-backed company raises more money than it can deploy and decides to give some back. A listed company completes a disposal and returns the surplus to investors. In each case the sums are large, the UK paperwork is professionally drafted, and the US consequences are rarely considered until the American shareholder's return is due.
The UK Rules: When HMRC Treats a Return of Capital as Capital
Under UK law, the starting point is company law. Furthermore, the tax result depends on whether the payment genuinely repays share capital or merely relabels profits.
Capital Reductions Under the Companies Act 2006
Section 641 of the Companies Act 2006 lets a company reduce its share capital in two ways. A private company limited by shares can pass a special resolution supported by a solvency statement, in which every director confirms the company can pay its debts for the next twelve months. Alternatively, any company, including a public company, can pass a special resolution confirmed by the court. Directors who make a solvency statement without reasonable grounds commit an offence, so the process is taken seriously.
A reduction can cancel paid-up share capital, cancel the share premium account, or reduce the nominal value of each share. The company can then either pay the released amount to shareholders immediately or credit it to distributable reserves for later dividends. That second choice matters enormously for UK tax, because a dividend paid out of reserves created by a reduction is an ordinary dividend, while a direct repayment of capital is not.
Why a Direct Repayment Is Not a UK Distribution
Section 1000 of the Corporation Tax Act 2010 defines a distribution broadly, but it excludes so much of a payment as represents a repayment of capital on the shares. Importantly, section 1025 of the same Act provides that a premium paid for new consideration counts as share capital for this purpose. Therefore, cash returned by cancelling a share premium account that investors actually funded is a repayment of capital, not an income distribution.
Instead of income tax, a shareholder who receives this kind of return of capital faces capital gains tax. Under section 122 of the Taxation of Chargeable Gains Act 1992, a capital distribution is treated as a part disposal of the shares. The shareholder deducts a proportion of their base cost, calculated by comparing the cash received with the value of the shares retained, and pays tax on the resulting gain at 18% or 24%, according to the current capital gains tax rates.
The Small Distribution Rule
Notably, a small capital distribution need not trigger a disposal at all. HMRC's Capital Gains Manual at CG57835 explains that HMRC regards a distribution as small if it is 5% or less of the value of the shares, and that it may also accept any distribution of £3,000 or less. In that case, the small return of capital simply reduces the base cost and is taxed on a later sale. A shareholder can, however, choose to treat a small distribution as a disposal, which can be useful where unused annual exemption is available.
B Share Schemes and Section 396A
For many years, listed companies used B share schemes to give shareholders a choice. Investors could take an income option, taxed as a dividend, or a capital option, in which B shares were redeemed and taxed as a capital disposal. That choice ended for UK income tax with section 396A of the Income Tax (Trading and Other Income) Act 2005, inserted by Finance Act 2015. Where a shareholder can choose between a distribution and an alternative receipt of substantially the same value, the alternative receipt is taxed as a distribution. The rule applies to receipts on or after 6 April 2015.
As a result, a UK resident individual who takes cash under a modern B share scheme is usually taxed at the dividend rates of 10.75%, 35.75% or 39.35% for 2026/27, as set out on the GOV.UK tax on dividends page. Historically, many such schemes also barred US shareholders from the capital option, forcing them onto the income route for securities law reasons.
Anti-Avoidance That Can Turn Capital Into Income
Two further UK rules deserve attention. First, section 1022 of the Corporation Tax Act 2010 treats a later bonus issue as a distribution where the company has previously repaid share capital, so a reduction followed by a capitalisation of profits can be recharacterised. Second, the transactions in securities rules in Part 13 of the Income Tax Act 2007 let HMRC counteract an income tax advantage where a close company returns cash in capital form. Owner-managed companies therefore often seek advance clearance before paying a return of capital to their shareholders.
The US Rules: Section 301 Ignores the Label
On the American side, the analysis of a return of capital is entirely different. Above all, the IRS does not care whether the UK company paid the cash out of share capital, share premium or retained profits.
Earnings and Profits Decide Everything
Section 301 of the Internal Revenue Code divides any distribution of property into three layers. First, the portion that is a dividend under section 316 is included in gross income. Second, the portion that is not a dividend reduces the shareholder's adjusted basis in the stock. Third, anything beyond basis is treated as gain from the sale or exchange of property. Only the second layer is a return of capital in the US sense.
Crucially, section 316 of the Internal Revenue Code defines a dividend as any distribution out of accumulated earnings and profits, or out of earnings and profits of the current year. Consequently, a UK company that has retained profits from earlier years will usually pay a dividend for US purposes, however carefully the UK documents describe a capital repayment. Accounting reserves and UK distributable profits are irrelevant. The test is US earnings and profits, which a US shareholder must compute.
The Current-Year Trap
Specifically, the current-year rule catches many shareholders off guard. Earnings and profits for the current year are measured at the end of the company's tax year, not on the date of payment. Therefore, a UK company with an accumulated deficit can still pay a taxable dividend if it is profitable in the year it pays the cash. Conversely, a company that is profitable at the payment date can end the year with a loss, turning a feared dividend into a genuine return of capital. The shareholder often cannot know the answer until the company's accounts close.
Computing Earnings and Profits for a UK Company
For a foreign corporation, earnings and profits are computed broadly under US tax principles, following Treasury Regulation 1.964-1, and in the company's functional currency, which is normally sterling. The dividend portion is then translated into dollars at the spot rate on the date of payment. Moreover, the computation adjusts UK accounts for items such as depreciation methods, tax provisions and unrealised gains, so the US figure can differ substantially from the UK balance sheet. Few UK companies prepare this calculation unless an American shareholder asks for it.
Basis Recovery, Share by Share
Once earnings and profits are exhausted, the remaining cash is a return of capital that reduces basis. Importantly, US courts apply this share by share. In Johnson v. United States, a 1971 appeals court decision, the court refused to let a shareholder pool basis across blocks of shares bought at different prices. Therefore, an investor who built a holding over several years must track each block. A distribution can exhaust the basis of a cheap early block and create a capital gain on it, even while a later, expensive block still has basis left.
When basis reaches zero, section 301(c)(3) treats the excess as capital gain, long-term if the block has been held for more than one year. In addition, both the dividend layer and the gain layer are investment income for the 3.8% net investment income tax, which no UK tax can offset.
Capital Reductions That Cancel Shares: The Redemption Question
A capital reduction can be carried out in two technically different ways, and the US analysis follows the mechanics rather than the commercial purpose.
Reducing Nominal Value or Cancelling Share Premium
Where a company reduces the nominal value of every share, or cancels its share premium account, no shares disappear. For US purposes, the shareholder simply receives a distribution, and section 301 decides how much of it is a true return of capital. Hence a pro rata return of capital of this kind is a dividend to the extent of earnings and profits, with any excess reducing basis.
Cancelling Shares Pro Rata
Alternatively, a company can cancel a proportion of each shareholder's shares and repay the capital on them. Under section 317(b), that is a redemption, so the shareholder first asks whether section 302 of the Internal Revenue Code grants sale treatment. However, a strictly pro rata cancellation leaves every shareholder with the same percentage as before. It cannot be substantially disproportionate, it does not terminate anyone's interest, and it is rarely a meaningful reduction. Accordingly, the payment falls back into section 301, and the basis of the cancelled shares moves across to the shares the shareholder still holds.
Non-Pro Rata Reductions
Occasionally, a reduction cancels only one class or one shareholder's shares, for example to buy out a departing investor. In that case section 302 can apply properly, and the departing shareholder may obtain exchange treatment. Meanwhile, the remaining American shareholders should check whether their percentage has risen. A reduction that lifts a US person above 10% of vote or value can create a new Form 5471 filing obligation, and one that lifts US ownership above 50% can make the company a controlled foreign corporation.
Share Consolidations Alongside a Return of Value
Listed companies often consolidate shares at the same time as a return of value, so that the share price is unaffected. For US purposes, a consolidation is normally a tax-free recapitalisation or exchange of common stock for common stock. Basis carries over to the new shares in proportion. Nevertheless, the consolidation and the cash payment are separate steps, and the cash still follows section 301.
Where the Two Systems Collide
The real cost of a return of capital for an American in Britain lies in the mismatch between the two analyses.
UK Capital, US Dividend
This is the most common pattern when an owner-managed company pays a return of capital. HMRC taxes a part disposal at 18% or 24%, while the IRS taxes a qualified dividend at up to 20% plus 3.8% net investment income tax. A UK company is normally a qualified foreign corporation under the US-UK treaty, so the 20% rate applies. Furthermore, the two taxes fall on the same cash in the same year, so the UK capital gains tax can usually be credited against the US tax on the dividend, provided the amounts are assigned correctly under the foreign tax credit regulations.
However, the credit is never perfect. The net investment income tax cannot be credited at all. Additionally, because the US treats the cash as a dividend, the shareholder's US basis is untouched, while the UK base cost has been partly used up. On a later sale, the UK gain will therefore exceed the US gain, and the extra UK tax on that later sale may exceed the US tax it can be credited against.
UK Dividend, US Return of Capital
The reverse pattern arises with B share schemes and with companies that have little or no earnings and profits. HMRC taxes the payment as a dividend at up to 39.35%, while the IRS treats it as a return of capital that only reduces basis. There is then UK tax but no US income in that year. Under Treasury Regulation 1.861-20, foreign tax on a payment the US treats as a return of capital is assigned to the category the earnings would have fallen into, usually passive. That tax can be claimed on Form 1116, but if there is no other passive foreign income it simply carries forward for up to ten years.
Controlled Foreign Corporations and Previously Taxed Earnings
Where the UK company is a controlled foreign corporation, the ordering changes again. Section 959 of the Internal Revenue Code treats distributions as coming first from previously taxed earnings and profits, which are excluded from income because the shareholder already paid US tax on them under subpart F or the former GILTI regime. Only after that layer do ordinary earnings and profits, and then basis, come into play. In addition, a distribution of previously taxed earnings can produce a foreign currency gain or loss under section 986(c), measured against the exchange rates when the earnings were originally included.
Passive Foreign Investment Companies
Where an American holds shares in a UK investment company that is a passive foreign investment company, the excess distribution rules in section 1291 of the Internal Revenue Code can reach a large one-off distribution, with tax at the highest ordinary rate plus an interest charge. How those rules interact with return-of-capital treatment is unsettled, so a PFIC shareholder should model any payout separately before it is paid.
Listed Company Returns of Value: What American Investors Should Expect
Large UK companies still return surplus cash, but the methods used for a listed return of capital have changed since 2015. Many now use special dividends, tender offers or on-market buybacks instead of B shares. Where a B share scheme is still used, it typically offers only an income route for UK purposes.
Reading the Company's US Tax Disclosure
Listed companies with a significant American shareholder base often publish a US tax section in their circular. Some also publish a statement similar to IRS Form 8937, which US issuers use to report how a corporate action affects basis. A UK company is not obliged to file one. Therefore, the American investor must often rely on the circular's description of the company's earnings and profits, which is usually phrased cautiously.
Brokerage Reporting Is Often Wrong
Moreover, US brokers frequently report a UK return of capital inconsistently. One broker may code the whole payment as a dividend on Form 1099-DIV, while another reports a nondividend distribution or nothing at all. UK platforms issue no US forms. The IRS Publication 550 section on nondividend distributions confirms that it is the shareholder who must reduce basis and report any excess as gain, so a wrong broker code does not change the correct answer.
Illustrative Case Study: A £900,000 Return of Capital
The following example is illustrative, uses rounded figures, and assumes an exchange rate of $1.30 to the pound.
The Facts
Eleanor is a US citizen who has lived in London for fifteen years. She owns 30% of a UK trading company she co-founded, having subscribed £1,200,000 for her shares, mostly as share premium. In 2026 the company sells a division and holds £3,000,000 of surplus cash. It cancels part of its share premium account under the solvency statement procedure and pays the £3,000,000 out pro rata. Eleanor receives £900,000. Immediately before the payment, her shares were worth £6,000,000. The company has accumulated US earnings and profits of about £8,000,000 from twelve years of trading, and it is not a controlled foreign corporation. Eleanor used her Business Asset Disposal Relief lifetime limit on an earlier sale.
The UK Result
Because the share premium was paid for new consideration, the payment is a repayment of share capital rather than a distribution. It is 15% of the value of her shares, so it is not small, and it is a part disposal. The allowable cost is £1,200,000 multiplied by £900,000 over £6,000,000, or £180,000. Her gain is £720,000. After the £3,000 annual exempt amount, capital gains tax at 24% comes to £172,080, or about $223,700.
The US Result
For US purposes, the label is irrelevant. The company has ample earnings and profits, so the whole £900,000, or $1,170,000, is a qualified dividend. Tax at 20% is $234,000, and the net investment income tax at 3.8% adds $44,460. Assuming her other income keeps her in the top bracket and the UK tax is correctly assigned to the same category as the dividend, the UK tax of about $223,700 credits against the regular US tax, leaving roughly $10,300 of regular tax. In practice, the qualified dividend rate adjustment to the foreign tax credit limitation can trim the credit further, so the true residual is often somewhat higher. Even on this simplified view, she still owes the $44,460 of net investment income tax, giving a combined US cost of about $54,800 on top of the UK bill.
The Hidden Second Cost
The larger problem comes later. Eleanor's UK base cost has fallen to £1,020,000, but her US basis is still the full dollar equivalent of £1,200,000, because the IRS never treated the payment as a return of capital. When she sells her shares, her UK gain will be £180,000 larger than her US gain. The extra UK tax on that difference, about £43,200 at 24%, will have no matching US income to sit against. Unless she has other foreign income in the right category, part of that tax becomes a permanent cost.
What Better Planning Would Have Changed
Had we been involved before the reduction, we would have modelled the company's US earnings and profits first. A company can sometimes pay dividends in an earlier year to bring forward the US income in a year when Eleanor has other foreign tax credits available. Alternatively, it can time the payment so that UK and US income fall in the same basket and the same year. For founders who intend to emigrate, timing the return of capital around a change of UK residence can also alter the UK side of the calculation. None of these steps is available after the cash has been paid.
Reporting a Return of Capital on Your US Return
Accurate reporting of a return of capital matters as much as the tax itself. Above all, the US return must reflect the US characterisation, not the UK one.
Where Each Layer Goes
The dividend layer goes on Schedule B and, for the qualified rate, through the capital gains worksheet. Any section 301(c)(3) gain goes on Form 8949 and Schedule D. UK tax paid goes on Form 1116, and the net investment income tax is computed on Form 8960. Meanwhile, the basis records for each block must be updated, because the next distribution or sale depends on them. Our US tax returns for expats service includes building and maintaining these records.
Information Returns You Cannot Ignore
Furthermore, the shareholding itself creates reporting. A direct holding in a UK company is a specified foreign financial asset on Form 8938, and a holding of 10% or more of vote or value can require Form 5471. If the shares sit in a UK brokerage or nominee account, that account goes on the FBAR. Our team handles these filings through our FBAR and FATCA reporting service, and our guide to directly held foreign stock on Form 8938 explains the valuation rules.
Matching the UK Return
On the UK side, a return of capital taxed as a capital distribution goes on the capital gains pages of the Self Assessment return, while a B share payment taxed as income goes on the dividend pages. Because the two returns describe the same cash differently, we keep a reconciliation on file showing why the figures differ. That reconciliation is invaluable if either tax authority asks questions later.
Missed Reporting After a Return of Capital
In our experience, a past return of capital is one of the commonest sources of missed reporting on otherwise careful US returns. The usual pattern is that the shareholder's UK adviser correctly reported a capital gain in Britain, while the US return showed nothing, because the cash was described as capital.
How to Put It Right
The fix depends on what was missed. Where only information returns such as Form 5471 or Form 8938 were omitted and all income was reported, a delinquent international information return submission may be appropriate. Where a dividend was omitted, amended returns are usually needed. For qualifying non-wilful taxpayers living abroad, the IRS Streamlined filing route can bring several years up to date at once. If FBARs were also missed, the FinCEN BSA E-Filing system is where late reports are submitted. Importantly, acting before the IRS makes contact preserves the most favourable options.
Recovering Credits for UK Tax Already Paid
Additionally, amending a return to add an omitted dividend usually means claiming foreign tax credits for UK tax paid on the same transaction. The period for claiming a foreign tax credit refund is generally ten years under section 6511(d)(3), which is far longer than the normal three-year window. Consequently, even an old return of capital can often be corrected with little net US tax, provided the UK tax was genuinely creditable.
How TaxYork Can Help
TaxYork prepares US and UK returns for American shareholders in British companies, and a return of capital is exactly the kind of transaction where joint preparation pays for itself. We compute the company's US earnings and profits, model the section 301 layers before the cash moves, track basis share by share, and align the UK and US foreign tax credit positions. In addition, we prepare the information returns that the shareholding requires and, where earlier years went wrong, we put them right through the most suitable correction route. Our tax treaty optimisation service addresses the credit mismatches described above, so that UK tax paid on a capital reduction is not wasted.
Conclusion
A return of capital from a UK company is a capital event in Britain and very often a dividend in the United States. HMRC looks at company law, share premium and the part disposal rules, while the IRS looks only at earnings and profits under section 301. As a result, an American shareholder can face UK capital gains tax and US dividend tax on the same payment, lose credit for the net investment income tax, and carry a basis mismatch into every later sale. Modern B share schemes can produce the opposite result, with UK income tax and no US income at all.
Therefore, the time to act is before the board approves the reduction. With the company's US earnings and profits modelled, the timing planned and the reporting prepared in advance, a return of capital can be handled efficiently on both returns. Without that work, it becomes an expensive correction exercise later.
