US Personal Tax Services: UK MVL With an American Shareholder

When an American winds up a solvent UK company through a members' voluntary liquidation, HMRC generally taxes the liquidator's distributions as capital gains, often at the 18% Business Asset Disposal Relief rate. The IRS treats the same payments as proceeds from a sale of the shares under section 331, and section 1248 can turn part of them into a dividend.

That split is the whole problem. One set of cash transfers from one liquidator produces two returns, on two different tax years, in two currencies and under two different theories of what the money is. Our US personal tax services for founders exiting UK companies focus on preparing both sides so they agree with each other: the same distribution dates, the same exchange rates, the same basis figures, and a foreign tax credit claim that actually uses the UK tax paid. This guide sets out what an American shareholder needs to see through, from the declaration of solvency to the final Form 5471.

What is a members' voluntary liquidation, and why does it matter to a US shareholder?

A members' voluntary liquidation (MVL) is the formal way to close a solvent UK company. The directors swear a statutory declaration of solvency confirming the company can pay its debts in full, with interest, within twelve months. The shareholders pass a special resolution to wind up and appoint a licensed insolvency practitioner as liquidator. The liquidator realises the assets, settles the creditors (HMRC included), and distributes what is left to the shareholders. The company is then dissolved.

For a UK-only shareholder, the main attraction is that distributions made by a liquidator are generally capital, not income. For an American shareholder, the attraction is only half there. US tax law has its own characterisation rules, and a UK company owned by US persons is very often a controlled foreign corporation (CFC). That brings in section 1248, previously taxed earnings, and a final set of international information returns that a UK liquidator will not prepare and may not know exist.

The typical fact pattern we see:

• A US citizen or green card holder, usually resident in the UK, owns most or all of a UK private limited company.
• The company has sold its trade or stopped trading and holds cash, sometimes with an investment portfolio, property or intellectual property.
• Reserves are well above the £25,000 limit that applies to informal strike-off distributions, so an MVL is needed to keep capital treatment in the UK.
• The liquidator makes an interim distribution soon after appointment and a final distribution once HMRC confirms it has no further claims. The two often land in different tax years on both sides of the Atlantic.

The UK side: how HMRC taxes MVL distributions

Why are MVL distributions capital rather than income?

The income tax definition of a distribution excludes amounts paid in respect of share capital in a winding up. So a payment from a liquidator is not a dividend. Instead, section 122 of the Taxation of Chargeable Gains Act 1992 (TCGA) treats a capital distribution as a disposal, or part disposal, of the shares. The shareholder pays capital gains tax (CGT) on the gain rather than income tax at dividend rates.

The gap between the two is large. For 2026/27, the dividend rates are 10.75% (ordinary), 35.75% (upper) and 39.35% (additional). The main CGT rates are 18% and 24%, and qualifying gains taxed under Business Asset Disposal Relief are charged at 18%.

Business Asset Disposal Relief: the current rate and conditions

Business Asset Disposal Relief (BADR) is now worth less than it used to be. The rate went up from 10% to 14% for disposals from 6 April 2025, and to 18% from 6 April 2026. The lifetime limit is still £1 million of qualifying gains. At 18%, BADR only saves anything for gains that would otherwise fall in the 24% band, so the relief is worth up to £60,000 over a lifetime. Please check the rate that applies to each distribution date. Anti-forestalling rules apply to contracts that straddle a rate change, and further changes are always possible. HMRC's summary is on the gov.uk Business Asset Disposal Relief page, and the detailed conditions are in the Capital Gains Manual at CG63955.

For a shareholder in a liquidated company, the main conditions are:

• The company must have been the shareholder's personal company. That means at least 5% of the ordinary share capital and voting rights, plus an entitlement to at least 5% of profits and assets available for distribution or of sale proceeds.
• The shareholder must have been an officer or employee of the company.
• The company must have been a trading company, or the holding company of a trading group.
• All of these must have been true for two years ending on the date the company stopped trading.
• The distribution must be made within three years of that date.

The three-year window matters. A company that sells its trade, sits on the cash for a while and only then goes into an MVL can miss it. BADR must be claimed by the first anniversary of 31 January following the tax year of the disposal.

The anti-phoenix rule: ITTOIA 2005 section 396B

Section 396B of the Income Tax (Trading and Other Income) Act 2005 is a targeted anti-avoidance rule (TAAR). It can treat a distribution in a winding up as income, taxed at dividend rates. Broadly, all four conditions must be met:

• Condition A: just before the winding up, the individual held at least a 5% interest in the company.
• Condition B: the company was a close company at any point in the two years before the winding up.
• Condition C: at any time within two years after the distribution, the individual carries on, or is involved with, a trade or activity that is the same as or similar to the company's, whether as a sole trader, partner, or through a company or connected person.
• Condition D: it is reasonable to assume that the main purpose, or one of the main purposes, of the winding up was to avoid or reduce income tax.

HMRC does not give advance clearance under section 396B, so the answer depends on evidence. When we prepare the return, we build a file that shows Condition C or Condition D does not apply. For example:

• A sale agreement for the trade to an unconnected buyer, with any restrictive covenants that stop the shareholder competing.
• Board minutes that record the real commercial reason for closing, such as retirement, relocation, a buyer who wanted only the assets, or a sector exit.
• A record of what the shareholder has done since, particularly any employment or consultancy in the same field. Taking a salaried job with the buyer is treated very differently from setting up a new company doing the same work.
• Where the position is arguable, a disclosure in the white space on the return, so HMRC cannot later claim it was not told.

For a US shareholder, the TAAR also affects the foreign tax credit. If HMRC recharacterises the distribution as income, the UK tax goes up and changes character, and the US return may need to be amended so the credit matches.

Interim and final distributions: the part-disposal computation

Each interim distribution is a part disposal of the shares. The base cost is apportioned using the standard A/(A+B) fraction, where A is the amount distributed and B is the market value of what the shareholder still holds, which is the right to later distributions. The liquidator's estimate of the final distribution is usually the best evidence of B. The final distribution then takes whatever base cost is left.

Where a distribution is small compared with the value of the shares, HMRC practice allows it to be deducted from base cost instead of being treated as a part disposal. In a real MVL, the interim distribution is almost never small. Distributions of assets in specie, such as a property, a portfolio or a loan note, are valued at market value on the date of distribution. The company is also treated as disposing of those assets at market value, which can create a corporation tax charge for the liquidator to settle before the final distribution.

Reporting on SA108

MVL gains go on the capital gains summary pages (SA108) of the self assessment return for the tax year in which each distribution is received. The UK tax year runs from 6 April to 5 April. CGT is due by 31 January after the end of that tax year. The 60-day real-time reporting regime applies to UK residential property disposals, not to share disposals. An interim distribution in December 2026 and a final distribution in May 2027 fall into two separate UK tax years, 2026/27 and 2027/28, with two BADR claims drawing on the same £1 million lifetime limit.

The US side: how the IRS taxes the same distributions

Section 331: a sale of the shares, not a dividend

Under section 331, amounts distributed in complete liquidation of a corporation are treated as full payment in exchange for the stock. The American shareholder recognises capital gain or loss equal to the dollar value of what they receive minus their dollar basis in the shares. Property received in specie takes a US basis equal to its fair market value when distributed, and its holding period starts again from that date.

This analysis assumes the UK company is treated as a corporation for US purposes. A private limited company is an eligible entity that can elect to be disregarded. If a check-the-box election was ever filed, the liquidation is treated as a distribution of assets by a branch, not a stock sale, and the analysis changes completely. Confirm the entity's US classification before anything else.

Basis in dollars, and translating each distribution

US basis is a historical dollar figure. It is the subscription price or purchase cost of the shares, translated at the exchange rate on the date it was paid, and adjusted for any later capital contributions. Each liquidating distribution is translated into dollars at the spot rate on the day it is received. Sterling held after it is received has its own dollar basis. If the shareholder later converts it at a different rate, the difference is a separate currency gain or loss, which is outside the liquidation computation. Using an annual average rate is a common shortcut and is wrong for a stock disposal of this size.

Section 1248: when the gain becomes a dividend

If the shareholder is a US shareholder (10% or more by vote or value) of a company that was a CFC at any time in the previous five years, section 1248 can recharacterise part of the section 331 gain as a dividend. The amount depends on the company's untaxed earnings and profits attributable to those shares. A complete liquidation counts as a sale or exchange for this purpose. We cover the mechanics, the individual tax limitation and the qualified dividend question in our separate guide to section 1248 on selling a UK limited company, and we do not repeat that analysis here.

Two points specific to liquidations are worth noting. First, earnings already taxed in the US under subpart F or GILTI (renamed net CFC tested income from 2026) are previously taxed earnings and profits. Distributions of those earnings are generally not taxed again, although currency gain or loss can arise on them, so the tracking schedules on past Forms 5471 now determine the result. Second, a company that holds only cash after selling its trade may appear to meet the passive foreign investment company (PFIC) tests. For a 10% US shareholder of a CFC, the CFC-PFIC overlap rule generally prevents PFIC treatment for the period the company is a CFC. A minority American investor may not get that protection.

When distributions span two US tax years

The US uses the calendar year. The UK tax year ends on 5 April. The IRS allows a shareholder receiving a series of liquidating distributions to recover their full basis before recognising any gain. Gain arises only once cumulative distributions exceed basis. A loss, by contrast, generally cannot be claimed until the final distribution is received. For a founder with a nominal £100 subscription, basis recovery makes almost no difference. For an American who bought into the company at a significant price, it can move most of the gain into the later US year, while the UK taxes a proportionate part disposal in the earlier one.

Net investment income tax

The 3.8% net investment income tax (NIIT) applies to US citizens and residents above the income thresholds ($250,000 for married filing jointly, $200,000 for single filers, not indexed). It applies to section 331 gain and to any section 1248 dividend. The IRS position is that foreign income tax cannot be credited against NIIT, so UK CGT generally does not reduce it. For a UK-resident American, NIIT is often the residual US tax that remains after the foreign tax credit.

The foreign tax credit mismatch between UK CGT and a US dividend or gain

This is where many returns go wrong. The UK charges CGT on a capital gain, while the US may be taxing a dividend under section 1248 and a gain under section 331. The treaty and the US foreign tax credit rules look at the tax paid and the income it relates to, not at the label each country uses. The practical problems are:

• Timing. UK CGT on a December distribution is paid the following January, over a year later. A cash-basis taxpayer can claim the credit when it is paid, or elect to claim it when it accrues. Any excess can be carried back one year and forward ten.
• Sourcing. A gain on shares sold by a US resident is usually US-source, which leaves no foreign-source income to credit against. For US citizens resident in the UK, the treaty's double taxation article can resource the income so the UK tax can be credited. That treaty-based position must be disclosed on Form 8833.
• Baskets. Liquidation gains and section 1248 dividends usually fall in the passive category, together with other investment income, which can dilute or absorb the credit limitation.
• Rate mismatch. Where the UK taxes at 18% or 24% and the US at 15% or 20% plus NIIT, the UK credit usually removes the regular US tax but leaves NIIT. Where HMRC applies the TAAR and charges 39.35%, the excess credit builds up unused unless there is other passive income to use it against.

Worked illustration with round numbers

These figures are illustrative only and are not a computation of anyone's liability.

A US citizen living in London has owned 100% of a UK trading company since subscribing £100 for its shares in 2014 (US basis about $160). She has been a director throughout. The company sells its trade to an unconnected buyer in 2026, and she signs a two-year non-compete. The company then enters an MVL with £2,000,000 of distributable cash after all creditors and the liquidator's fees are paid. The company has never filed a check-the-box election. It has around £1,900,000 of accumulated earnings, and no previously taxed earnings because its trading profits were high-taxed.

• Interim distribution: £1,200,000 in December 2026, at an assumed $1.30 rate = $1,560,000. UK tax year 2026/27, US tax year 2026.
• Final distribution: £800,000 in May 2027, at an assumed $1.25 rate = $1,000,000. UK tax year 2027/28, US tax year 2027.

UK. For the interim distribution, cost allocated is £100 × 1.2m/2.0m = £60, giving a gain of roughly £1,199,940. BADR covers the first £1,000,000 at 18% (£180,000), and the remaining gain of about £199,940 is taxed at 24% (about £47,986). The total is about £228,000, due 31 January 2028. The final distribution uses the remaining £40 of cost and the BADR lifetime limit has been used up, so the gain of about £799,960 is taxed at 24%. That is roughly £192,000, due 31 January 2029. The TAAR file relies on the sale to an unconnected buyer and the non-compete, which support the position that Condition C cannot be met.

US. Basis recovery barely matters because basis is only $160. The 2026 return reports about $1,559,840. Most or all of that is likely to be a section 1248 dividend because the company's earnings exceed the distributions, and qualified dividend treatment is typically available for a UK treaty company. Federal tax at 20% (about $312,000) plus NIIT at 3.8% (about $59,000) comes to roughly $371,000 before credits. The UK CGT of about £228,000 (about $296,000 at an assumed rate) is credited against the regular tax once resourced under the treaty. That leaves around $16,000 of regular tax plus the $59,000 of NIIT. The 2027 return follows the same pattern for the final distribution. Because the UK tax on each distribution is paid in the January after the following year, the accrual election and the carryforward rules decide whether the credit is used on time or needs an amended return.

If HMRC had applied the TAAR, the UK tax on the same money would have been about £787,000 at 39.35%, far more than the US could credit. That is why the section 396B evidence file is part of the US return preparation.

Company-level final-year obligations the owner must see through

The liquidator deals with the company's UK affairs. The US filings are the owner's responsibility. In our experience these are the items most likely to be missed:

• Final Form 5471. A US shareholder, officer or director of a UK company files Form 5471 for each year, including the year the company is dissolved. The final filing reports the liquidating distributions, the disposition of the shares and the closing earnings and profits and previously taxed earnings balances. IRS instructions are on the About Form 5471 page. The penalty for a missing form starts at $10,000 per form per year, and the statute of limitations on the whole return stays open until it is filed.
• FBAR on the company's accounts until closed. An owner with more than 50% of the company has a financial interest in its bank accounts. A director with signing authority has an FBAR obligation as well. Those accounts belong on the FinCEN Form 114 for every year they are open, including the year the liquidator closes them. See the IRS FBAR guidance. Our FBAR penalty calculator shows the exposure if earlier years were missed.
• Form 8938. The shares themselves are a specified foreign financial asset until they are fully disposed of, and are reported on Form 8938 above the relevant thresholds, alongside any sterling cash received and held.
• Final CT600. Going into liquidation ends a corporation tax accounting period. The liquidator files CT600s for the liquidation period or periods and asks HMRC to confirm it has no further claims before making the final distribution. The owner needs copies, because the UK corporation tax paid affects earnings and profits and the high-tax analysis on the final Form 5471.
• Distribution records. Keep the liquidator's distribution notices, showing the date, amount and any in-specie valuation, the declaration of solvency and the final account. Both returns depend on them.

Owners who find that earlier Forms 5471 or FBARs were never filed should deal with that before the liquidation return is prepared. A final Form 5471 filed alone is easy to spot. Our IRS streamlined filing team regularly handles catch-up alongside an exit.

Preparing the returns: a practical sequence

• Confirm the entity's US classification and the shareholder's US basis in dollars, with evidence.
• Get the earnings and profits and previously taxed earnings history from past Forms 5471, or rebuild it if it was never kept.
• Agree the expected distribution timetable with the liquidator, including the likely split across UK and US tax years.
• Assemble the BADR qualifying facts and the section 396B evidence file.
• Prepare SA108 for each UK tax year and the Form 1040, Form 1116, Form 8833 and final Form 5471 for each US year from the same data.
• Diarise the FTC accrual position, the carryforward, and any amended return needed when the UK tax is finally paid.
