US Personal Tax Services: UK Capital Reduction and §301

When a UK private company repays share capital or share premium to an American shareholder, the UK usually treats the cash as a capital receipt: a part disposal of the shares for capital gains tax. The US applies section 301 instead. The payment is a dividend up to the company's US-measured earnings and profits, then a return of basis, and only after that a capital gain.

That mismatch is where specialist US personal tax services earn their fee. A capital reduction is usually well planned from a UK company-law point of view: the solvency statement is signed, the special resolution passed and the filing made at Companies House. The US side, though, tends to get looked at only when the Form 1040 is due. By then the shareholder is holding a UK capital gains computation for a payment the IRS sees as largely dividend income, and there is a UK tax bill that does not fit neatly into the foreign tax credit rules. This guide covers how Jungle Tax prepares both returns for this transaction, what the paperwork needs to show, and how to rebuild the position when the reduction happened in a year that was never filed.

What is a capital reduction, and why do UK companies use one?

Under Part 17 of the Companies Act 2006, a private limited company can reduce its share capital. That includes its share premium account, which company law treats as part of capital. There are two routes. One is a special resolution backed by a directors' solvency statement, which is the usual route for private companies. The other is a special resolution confirmed by the court. With the solvency-statement route, every director confirms that the company can pay its debts as they fall due for the next twelve months. The company then files the resolution, the solvency statement, a statement of capital and a statement of compliance at Companies House, normally within 15 days.

Owner-managed and founder-led companies use a capital reduction for several reasons:

• To return surplus cash after a partial exit, a large contract receipt or a sale of part of the business, when the company has too few distributable reserves to pay a dividend.
• To release a large share premium account built up by earlier funding rounds, so the capital can be returned to investors.
• To eliminate a deficit on the profit and loss account, so the company can pay dividends again later.
• As a step before a sale, demerger or restructuring, to tidy the balance sheet.

For the shareholder, the key question is what happens to the amount released, and it can happen in two quite different ways.

Direct repayment versus the reserve route

The company can repay the reduced capital to shareholders directly, as part of the reduction itself. Alternatively, it can credit the amount released to a reserve and later pay it out of that reserve, usually as a dividend. Under the Companies (Reduction of Share Capital) Order 2008, a reserve created by a reduction can generally be treated as a realised profit, and so becomes distributable. HMRC's guidance at CTM15440 spells out the consequence. A payment made directly on the reduction is a repayment of share capital. A payment made out of the reserve the reduction created is generally a distribution: a dividend, taxed as income. The UK tax treatment therefore depends on the mechanics, and the board minutes need to show clearly which route was taken.

Is a repayment of share premium taxed as income or capital in the UK?

For an individual, a direct repayment of share capital is generally not an income distribution. The definition of "distribution" in section 1000 of the Corporation Tax Act 2010 excludes any part of a payment that represents a repayment of share capital. Under CTA 2010 s.1115, share premium paid on the issue of shares is generally treated as part of that share capital when working out how much of a payment is a repayment. So cancelling a genuine subscription premium and paying it back to the subscriber is normally capital, not income.

Watch for the bonus issue rules. Under CTA 2010 s.1026, share capital that was paid up by capitalising reserves (a bonus issue), rather than subscribed for new consideration, is generally not "share capital" for this purpose. A later repayment of it is treated as a distribution until repayments exceed the bonus amount, subject to limited exceptions. The reverse sequence is caught too. Where a company repays share capital and then makes a bonus issue, CTA 2010 s.1022 can treat the bonus issue as a distribution. Before assuming that a reduction produces capital treatment in the UK, check the company's share capital history back to incorporation, and look closely at any capitalisation of reserves.

Two further UK points are worth noting. First, HMRC can apply the transactions in securities rules in Part 13 of the Income Tax Act 2007 where a capital return is used, in substance, to extract profits that would otherwise have been paid as dividends, especially where retained earnings are large. CTM15440 confirms that capital treatment does not stop those rules applying. Second, the government has consulted on modernising the taxation of distributions and repayments of capital. The rules in force for the payment date should be confirmed when the return is prepared.

How is a capital distribution reported for UK capital gains tax?

Where the repayment is not income, it is a "capital distribution" within section 122 of the Taxation of Chargeable Gains Act 1992. The shareholder is treated as having disposed of an interest in the shares, with proceeds equal to the cash received, even though the shareholder usually still holds the same number of shares. HMRC's Capital Gains Manual at CG57800 sets out the framework.

• Part-disposal computation. The allowable cost is apportioned using the standard A/(A+B) formula. A is the distribution, and B is the market value of the shares retained immediately afterwards. For a private company, that means a supportable valuation.
• The small distribution rule. Under s.122(2), if the distribution is "small", the shareholder can deduct it from base cost instead of computing a gain, which postpones the gain until a later disposal. HMRC's long-standing practice treats a distribution as small if it is 5% or less of the value of the shares, and will also generally accept amounts of £3,000 or less.
• Distributions exceeding base cost. Where the distribution exceeds the allowable expenditure, s.122(4) allows the shareholder to elect to set all the remaining cost against it, so the base cost falls to nil.
• Rates and reliefs. Main rate CGT on shares is 18% or 24%, depending on the individual's income. Business Asset Disposal Relief may reduce the rate on a qualifying part disposal, subject to its conditions and lifetime limit. The £3,000 annual exempt amount applies.
• Reporting. The gain goes on the capital gains pages of the Self Assessment return for the UK tax year (6 April to 5 April) in which the distribution is received. Tax is due by 31 January following the end of that tax year.

The UK charge depends on where the shareholder is resident. A US citizen who is UK resident is taxed in the UK on the gain. A shareholder who is resident only in the US is generally outside UK CGT on shares in a UK trading company, although the temporary non-residence rules can apply to someone who left the UK recently and returns within five years. This matters a great deal for the foreign tax credit analysis below.

How does the IRS treat a return of capital from a UK company?

US federal tax law looks at what the payment does economically, not what it is called under UK company law. A cash payment from a corporation to a shareholder in respect of stock is a distribution under section 301 of the Internal Revenue Code. Section 301(c) then applies a fixed three-tier order:

1. Dividend to the extent of the company's earnings and profits (E&P) under section 316. That means current-year E&P first, then accumulated E&P since 1913.
2. Return of capital, which is tax-free and reduces the shareholder's US tax basis in the shares, down to zero.
3. Capital gain for anything beyond both E&P and basis.

Section 301 has no exception for a repayment of share capital or a cancellation of share premium. A UK label, a Companies House filing or an entry debiting the share premium account does not change the result. If the company has E&P, the payment is a dividend for US purposes, even though HMRC treats it as capital.

E&P is not the same as UK distributable reserves

Many prepared returns go wrong on this point. E&P is a US tax concept, computed from the company's accounts with adjustments under US principles. UK distributable reserves, or the retained earnings figure in the statutory accounts, are a company-law measure. The two can differ significantly. Common differences include:

• Depreciation differences, including US rules for property, plant and intangibles.
• Timing differences on provisions, accruals and deferred tax.
• US disallowances, and US-specific rules on share-based remuneration.
• Translation. E&P of a UK company is computed in its functional currency, normally sterling.
• Previously taxed earnings and profits (PTEP) where the company is a controlled foreign corporation.

Also important is that current E&P is measured at the end of the year of the distribution and is used first, even if the company has an accumulated deficit. A company with years of historic losses that turns a profit in the year of the reduction can therefore pay a taxable dividend, even when its balance sheet shows no distributable reserves at all. This is sometimes called a "nimble dividend" in US practice.

Qualified dividend status under the US-UK treaty

A UK company that is eligible for benefits under the US-UK income tax treaty is generally a "qualified foreign corporation". Dividends from it can therefore be qualified dividends, taxed at the long-term capital gains rates of 0%, 15% or 20%, provided the holding period is met (more than 60 days in the 121-day window around the ex-dividend date). The 3.8% net investment income tax may apply on top for higher earners. Qualified status is lost if the company is a passive foreign investment company, which rarely applies to a genuine UK trading company but should still be checked for investment-heavy holding companies. For a controlled foreign corporation, it is also important to know whether any part of the distribution comes out of PTEP. That part is excluded from income under section 959 and is not taxed as a dividend again, although foreign currency gain or loss under section 986(c) may arise.

Can UK capital gains tax be credited against a US dividend?

This is the hardest part of the transaction for a UK-resident American. The UK taxes a gain and the US taxes a dividend, and the foreign tax credit rules were written to match foreign taxes to US income. Three problems come up.

1. Matching the tax to the right income and basket

Under the current foreign tax credit regulations, a foreign tax is allocated to the US income that the same transaction produces, even when the two countries characterise that transaction differently. Where the UK taxes as a gain what the US treats as a section 301 distribution, the UK tax should generally follow the US character of the distribution. It is therefore matched against the dividend, and against any section 301(c)(3) gain, rather than left unused. That tax must then go in the right basket. For most individual shareholders, a dividend from a foreign company is passive category income. Where the shareholder is a 10%+ US shareholder of a controlled foreign corporation, look-through rules can place the dividend in the general category, in line with the company's underlying trading income. Getting the basket wrong can leave a large UK tax payment stranded.

2. The qualified dividend rate adjustment

Where foreign-source qualified dividends are taxed at preferential rates, section 904(b) scales them down in the limitation fraction. This limits the credit to roughly the US tax actually charged on the dividend. If UK CGT at 24% exceeds the US tax on the same payment at 20%, the excess is not lost immediately. It can generally be carried back one year and forward ten years in the same basket.

3. Timing

The UK tax year ends on 5 April. An accrual-basis foreign tax credit claimant generally accrues UK tax on the last day of the UK tax year to which it relates. A capital reduction paid in, say, November 2026 falls into US tax year 2026. The UK CGT on it relates to the UK tax year ending 5 April 2027, so under the accrual method it accrues in US tax year 2027. A cash-basis claimant would claim it only when paid, on 31 January 2028. Without planning, the dividend is taxed in one US year and the credit arrives in another. The one-year carryback, an election to claim credits on an accrual basis, and careful sequencing of the returns are how this is managed. It also affects US estimated tax payments for the year of the distribution.

The US net investment income tax is a separate issue. The IRS position is that foreign tax credits do not offset the 3.8% NIIT, so a UK resident may pay NIIT even where the income tax is fully credited. It should be budgeted for rather than assumed away. For forms and instructions, see the IRS pages for Form 1116 and Form 5471.

Worked illustration: £800,000 of share premium returned

Round numbers, for illustration only. Assumes a US citizen resident in the UK throughout, and an exchange rate of $1.30 to £1.

Olivia, a US citizen living in London, subscribed for 100% of a UK trading company in 2019, paying £10 nominal and £990,000 of share premium. Her UK base cost is £990,010. Her US basis, translated at the 2019 historic rate, is $1,250,000. In 2026 the company cancels £800,000 of its share premium using the solvency-statement route and repays it to her in cash directly, in November 2026. The retained shares are valued at £2,200,000 immediately afterwards. The company's E&P under US principles is £500,000 accumulated at the start of the year plus £100,000 current-year E&P. For simplicity, assume no PTEP.

UK computation (tax year 2026/27)

• Capital distribution: £800,000. This is not small, so there is a part disposal.
• Apportioned cost: £990,010 × 800,000 / (800,000 + 2,200,000) = about £264,003.
• Gain: about £535,997, less the £3,000 annual exempt amount, which leaves about £532,997.
• CGT at 24%: about £127,919, or less if Business Asset Disposal Relief applies to part of the gain.
• Remaining UK base cost: about £726,007.

US computation (tax year 2026)

• Dividend: £600,000 (£100,000 current plus £500,000 accumulated E&P), which is $780,000. It is a qualified dividend, so tax at 20% is about $156,000, plus NIIT at 3.8% of about $29,640.
• Return of basis: the remaining £200,000 ($260,000) reduces her US basis from $1,250,000 to $990,000. No US gain arises.
• Foreign tax credit: UK CGT of about £127,919 (roughly $166,000 at an illustrative rate) is available against the dividend. It is limited broadly to the US tax on that income in the right basket, and the timing mismatch described above applies. Excess credit carries back or forward.

The result is that one payment is a £532,997 gain in the UK and a $780,000 dividend in the US. The UK tax should broadly cover the US income tax on the dividend, but NIIT and timing leave a real cost unless the returns are prepared together. If the company had instead shown an accumulated deficit and no current-year profit, the whole payment would have been a return of basis in the US and no US tax would arise, while the UK gain stayed the same.

How does this differ from a share buyback under section 302?

A pure share premium reduction cancels no shares, so there is no exchange and section 302 does not apply. The payment goes straight to section 301. Where a reduction of capital actually cancels shares, the question is whether it qualifies as a redemption treated as an exchange. A cancellation made pro rata across all shareholders leaves each proportionate interest unchanged, so it will usually fail the section 302(b) tests and fall back to section 301 dividend treatment. Where a reduction cancels shares non-pro rata, our guide to the US tax treatment of a UK company share buyback under section 302 sets out the redemption tests and attribution rules, which apply in the same way.

Form 5471 and the E&P schedules for 10%+ owners

A US person who owns 10% or more of a UK company, by vote or value, will usually have a Form 5471 filing obligation. The category depends on control and ownership. For a capital reduction, the relevant schedules include:

• Schedule C and Schedule F: income statement and balance sheet, showing the share premium cancellation and the cash paid out.
• Schedule H: current E&P, reconciling statutory profit to US E&P.
• Schedule J: accumulated E&P by category, showing the reduction for the distribution.
• Schedule P: PTEP, where the company is a CFC and earlier inclusions exist.
• Schedule M: transactions between the company and its shareholders, which should include the distribution.

The dividend amount on the Form 1040 should reconcile with Schedules H and J. If the individual return shows a return of capital while the Form 5471 shows E&P available, that inconsistency is an obvious examination risk. For a CFC, the E&P history also reflects any earlier Subpart F or tested income inclusions. That history is what determines how much of the distribution is PTEP, and so tax-free.

What paperwork should the shareholder get from the company?

Before the returns are prepared, the shareholder should have:

• The special resolution, the directors' solvency statement (or the court order), and the Companies House filings, including the statement of capital.
• Board minutes showing whether the amount was repaid directly on the reduction or credited to a reserve and later paid out.
• A share capital history back to incorporation, identifying any bonus issues or capitalisations of reserves.
• The date and sterling amount of the payment, and the bank receipt.
• A valuation of the retained shares at the payment date, for the UK part-disposal computation.
• The company's statutory accounts for the year of payment and prior years, plus the working papers needed to compute current and accumulated E&P under US principles.
• Where the company is a CFC, the history of Subpart F, GILTI or tested income inclusions and the PTEP accounts.

Catch-up: the reduction happened in a year you never filed

We often see a capital reduction discovered only when an American shareholder starts bringing their US filings up to date. The UK return may have been filed correctly, showing a modest capital gain, while no US return was filed at all. In that case, the E&P has to be reconstructed after the event.

1. Establish the E&P baseline. Rebuild E&P from incorporation, or from the date the shareholder became a US person or acquired the shares, using each year's statutory accounts and US adjustments. Where full records are not available, a reasoned, documented reconstruction from filed accounts is usually the practical approach.
2. Allocate current E&P for the year of the reduction across all distributions in that year, pro rata, before using accumulated E&P.
3. Rebuild US basis at historic exchange rates, so that any non-dividend portion is correctly treated as a basis reduction or gain.
4. Prepare the missing Forms 5471 with consistent Schedules H, J and P, and remember that a missing Form 5471 can keep the statute of limitations open for the whole return under section 6501(c)(8).
5. Claim the foreign tax credit for the UK CGT actually paid, taking account of the carryback and carryforward years.
6. Choose the right compliance route. For eligible non-willful taxpayers, the IRS streamlined filing procedures, including the Streamlined Foreign Offshore Procedures for those who meet the non-residency test, generally require three years of amended or delinquent returns and six years of FBARs. They are designed so that information-return penalties are not generally imposed on eligible taxpayers. Where the shareholder also has UK bank, investment or ISA accounts that were never reported, the same package covers FBAR and Form 8938.

A capital reduction in a catch-up year is often where the US tax actually lies. A founder who thinks there is "nothing to report because it was capital" may have a substantial US dividend, possibly offset by credits, sitting in an unfiled year.

How we prepare returns for a UK capital reduction

Our work on these transactions is return preparation and compliance. We start from the company documents, reconstruct E&P, and prepare the UK Self Assessment capital gains computation and the US Form 1040, Form 1116 and Form 5471 together, so that the two sides are consistent. For clients with wider cross-border reporting, we coordinate this with their US-UK tax accountants engagement, and with high-net-worth reporting where there are several holdings, funding rounds or share classes.

If your UK company has returned share capital or share premium to you, or is about to, and you are a US citizen or green card holder, have the E&P position checked before the US return is prepared, or before the reduction is paid if possible. To discuss the preparation of your returns, or a catch-up for an earlier year, in confidence, please contact our cross-border team.
