This is general information, not tax advice. 21DC is not a tax adviser and is not authorised by the FCA or SEC. The UK tax treatment of distributions from non-UK companies depends on facts that differ between investors, and on law that HMRC is consulting on changing. Take advice from a qualified UK tax adviser before relying on any of this.
This guide covers UK-resident individuals holding Strategy's STRC or Strive's SATA directly, outside an ISA or pension. The same points apply broadly to Strategy's other dollar series and to Strive's SATS.
What the issuers say about US tax
Both issuers describe their preferred distributions as a return of capital for US federal tax purposes.
- Strategy's 8-K of 31 August 2026 says that, as of 1 September 2026, it expects the dividends payable on 30 September and 15 October 2026 to be "non-taxable returns of capital to the extent of a shareholder's tax basis" for US federal income tax purposes.
- Strive's 8-K of 13 October 2026 says it has no accumulated earnings and profits and does not expect to generate current earnings and profits in the current year or the foreseeable future. On that basis, it expects SATA distributions to be treated as recovery of capital for US investors and as exempt from US dividend withholding for non-US investors.
Under US rules, a distribution is a dividend only to the extent it comes out of the company's current or accumulated "earnings and profits". Anything beyond that reduces the holder's US tax basis. These are US concepts, and both issuers' statements are expectations that can change from year to year.
US withholding
US payers withhold tax on dividends paid to non-US persons. The default rate is 30%. With a valid W-8BEN, the UK–US treaty limits it to 15% for portfolio holdings (Article 10(2)(b)).
IRS Publication 515 says a distributing corporation or intermediary must withhold on the entire distribution. It may, however, elect not to withhold on the part that is not paid out of earnings and profits, "based on a reasonable estimate". In practice, whether US tax is withheld from a STRC or SATA payment depends on how the issuer and each intermediary in the chain apply that election. Your platform's statements show what was actually withheld.
If US tax was withheld on an amount later confirmed as a return of capital, the route to recover it is through the US system, for example a Form 1040-NR claim. It is not a UK claim.
UK income tax: income or capital?
The UK does not follow the US label. UK-resident individuals are taxed on dividends from non-UK companies under Chapter 4 of Part 4 of ITTOIA 2005. HMRC's Savings and Investment Manual at SAIM5210 says the charge excludes "dividends of a capital nature". The test is whether the "corpus of the asset" is left intact after the distribution.
HMRC adds that whether a payment is capital depends on the distribution mechanism under the law where the company is incorporated. A large dividend is not capital just because it is large. HMRC cites HMRC v First Nationwide [2012] EWCA Civ 278 for this. A capital reduction, as in Rae v Lazard, is different. The Company Taxation Manual at CTM15150 states HMRC's view that a dividend permitted under the law governing a foreign company is treated as a dividend unless there is evidence questioning its legal form. In 2024 the Upper Tribunal applied the same approach to individuals in Beard v HMRC.
STRC and SATA dividends are declared by the board as regular preferred dividends under Delaware and Nevada corporate law respectively. They are not presented as reductions of share capital. On HMRC's published approach, that points towards treating them as foreign dividend income in the UK, whatever their US label. 21DC cannot confirm how HMRC would view a particular payment.
HMRC consulted between 23 June and 14 September 2026 on bringing distributions from non-UK companies within the UK's statutory distributions rules (ATT summary). As of 22 October 2026 no outcome has been published.
UK dividend tax rates
For the 2026 to 2027 tax year, gov.uk gives the following:
- a dividend allowance of £500;
- a basic rate of 10.75%;
- a higher rate of 35.75%;
- an additional rate of 39.35%.
Foreign dividends are taxed on the full sterling amount arising, before any foreign tax is deducted. Any US tax withheld can usually be offset through Foreign Tax Credit Relief, but relief is generally limited to the treaty rate of 15%. Tax withheld above that rate has to be reclaimed from the IRS, not HMRC.
If a payment is treated as capital
If a distribution were treated as capital in the UK, it would fall under the capital gains rules for capital distributions (section 122 TCGA 1992), explained in HMRC's Capital Gains Manual at CG57800. A capital distribution is treated as a part disposal of the shares. It uses up part of your allowable cost. Where it is small relative to the holding, it may instead be deducted from base cost under the rules at CG57835. Do not assume this treatment applies just because the issuer reports a US return of capital.
Separately, selling the shares is a disposal for capital gains tax. Your gain is calculated in sterling, using the exchange rate on the date of acquisition and on the date of disposal.
Reporting
According to gov.uk, you need to tell HMRC if your dividends exceed your unused Personal Allowance and the £500 dividend allowance. Foreign income and Foreign Tax Credit Relief are normally reported on the Self Assessment Foreign pages (SA106).
Daily-paying series such as SATA and SATS generate many small payments, so keep platform statements showing each gross amount, any US tax withheld and the exchange rate used. Dividends and gains inside a stocks and shares ISA or a registered pension are not taxed in the UK and are not reported.
What to check before relying on this
- The issuer's latest tax statement for the year in question. Strategy and Strive describe expectations, which can change.
- Your platform's annual tax statement, showing gross distributions, US tax withheld and the exchange rates applied.
- That your W-8BEN is valid, and what withholding rate your platform applied.
- The outcome of HMRC's 2026 consultation on distributions from non-UK companies.
- Advice from a qualified UK tax adviser on whether your distributions are income or capital, especially if the amounts are significant.
Questions
If Strategy says a STRC distribution is a return of capital, is it tax-free in the UK?
Not necessarily. The return-of-capital label describes US federal tax treatment. It depends on the issuer's US earnings and profits. UK tax treatment is decided under UK law. HMRC's manuals say a foreign distribution is income unless it is of a capital nature, which depends on how the payment is made under the company law of the issuing company. A regular preferred dividend is generally treated as income in the UK, but you should take advice on your own position.
What rate of US tax is withheld from STRC or SATA payments to UK investors?
It depends on how the payer treats the distribution. US rules let a withholding agent withhold on the whole distribution, or not withhold on the part reasonably estimated not to come from earnings and profits. If it withholds, the UK–US treaty rate for portfolio dividends is 15% with a valid W-8BEN. Strive says it expects SATA distributions to be exempt from US dividend withholding for non-US investors. Check your platform statements for what was actually withheld.
What are the UK dividend tax rates for 2026 to 2027?
According to gov.uk, the dividend allowance is £500. Dividend income above it is taxed at 10.75% in the basic rate band, 35.75% in the higher rate band and 39.35% in the additional rate band, for the tax year from 6 April 2026 to 5 April 2027.
Do I have to report foreign dividends to HMRC?
gov.uk says you need to tell HMRC if your dividends exceed your unused Personal Allowance and the £500 dividend allowance. Foreign dividends are usually reported on the Foreign pages (SA106) of a Self Assessment return, which is also where Foreign Tax Credit Relief is claimed. Dividends received inside an ISA or SIPP are not reported.
