UK Tax on Foreign Dividends: A Practical Guide

Foreign dividends are a common feature of diversified investment portfolios. Whether you hold US technology stocks through an individual share dealing account, receive distributions from a European equity fund, or draw income from an offshore corporate structure, the UK tax treatment of these payments matters — and is frequently misunderstood.

This guide sets out the current rules, the practical steps for declaration, how to claim credit for foreign tax already withheld, and a note on the significant distinction between reporting and non-reporting funds.

The Dividend Allowance

For 2026/27, the UK dividend allowance stands at £500. This allowance covers both UK and foreign dividends — it is not doubled for overseas income. If your total dividend income (from all sources) is £500 or less, no income tax is payable.

The allowance was reduced from £1,000 (2023/24) and from £2,000 (2022/23 and earlier). The direction of travel has been clearly downward, and no reversal has been signalled by the current government.

Above the allowance, dividends are taxed at:

• 8.75% for basic rate taxpayers
• 33.75% for higher rate taxpayers
• 39.35% for additional rate taxpayers (earnings over £125,140)

These rates apply regardless of whether the dividend comes from a UK company or a foreign company. Foreign dividends are not treated more harshly than domestic ones — but the interaction with withholding tax (see below) adds a layer of complexity.

Self-Assessment Declaration

Foreign dividend income must be declared on your UK self-assessment return, specifically on the SA106 (Foreign) pages. The relevant section is "Dividends from foreign companies".

The amount to declare is the gross dividend — before any foreign withholding tax has been deducted. You then claim a credit for the foreign tax suffered. Do not declare only the net amount received; this is a common error that results in incorrect tax calculations.

If your foreign dividend income plus other investment income causes your total income to exceed the basic rate threshold, or if combined investment income exceeds £10,000, you will typically be required to register for self-assessment and file a return — even if employed through PAYE.

Foreign Tax Credit Relief

Most countries deduct tax at source before dividends are paid to foreign shareholders — this is known as withholding tax. The rate depends on the domestic law of the paying country and any applicable double taxation treaty with the UK.

The Foreign Tax Credit Relief (FTCR) mechanism allows you to set the foreign withholding tax against your UK income tax liability on the same income. The credit is capped at the lower of:

• The foreign tax actually deducted
• The UK tax that would apply to the same income

If the foreign withholding tax rate is lower than the UK rate on that income (e.g. 15% foreign withholding vs 33.75% UK higher rate), you pay additional UK tax to make up the difference. If the foreign withholding is higher than the UK rate, you only get credit up to the UK rate — the excess is not generally refundable in the UK, but may be deductible as an expense in some cases.

US Dividends and the 15% Treaty Rate

The US-UK double taxation convention provides for a 15% withholding tax on ordinary dividends paid by US companies to UK individual investors. This is the treaty rate — lower than the standard US withholding rate of 30% for payments to non-treaty-country investors.

To benefit from the 15% rate, UK investors typically need to complete a W-8BEN form and provide it to their broker or custodian. Most UK-based brokers and platforms manage this automatically for individual accounts, but it is worth confirming with your provider.

US-domiciled exchange-traded funds (ETFs) and mutual funds pay dividends subject to the same 15% withholding. However, UK investors holding US ETFs directly face an additional issue: from the UK's perspective, if the US ETF is not a "reporting fund" for UK tax purposes, gains on eventual sale are taxed as income (not CGT) — see the reporting fund section below.

Dividend reclaim procedures for US income: If withholding has been applied at the wrong rate (e.g. 30% instead of 15%), you can file a US tax reclaim using IRS Form 1040NR or, in many cases, a simpler refund request. The timeframes are long — typically 12–18 months — and the process benefits from specialist assistance.

French Dividends and Historical Context

France historically imposed a significant précompte mobilier (advance levy) and subsequently the avoir fiscal (tax credit) on dividends paid to non-resident shareholders, the latter abolished in 2004. Post-abolition, the standard French withholding tax on dividends to non-residents is 12.8% under the French flat tax, or 30% in the absence of a treaty.

Under the UK-France double taxation treaty, the withholding rate for UK individual investors is typically 15%. Some categories of shareholders (notably pension funds) may be eligible for a lower rate or full exemption.

Since 2019, French domestic law has allowed non-resident investors to apply for a refund of any withholding tax deducted in excess of the treaty rate, by submitting a claim to the Direction des Non-Résidents in Paris. Claims must be made within three years of the year in which the withholding occurred.

Note: Since Brexit, UK investors no longer benefit from EU-level dividend tax coordination mechanisms (the Parent-Subsidiary Directive or the Merger Directive). Treaty-based relief remains available, but the administrative process may be more burdensome than for EU-based investors.

ETFs and the Reporting Fund Regime

The UK's reporting fund regime is critically important for investors in collective investment schemes — including UCITS funds and exchange-traded funds registered overseas.

Under UK tax law, gains on the disposal of shares in an overseas fund are typically taxed as income (at up to 45%) rather than as capital gains (at up to 24%). However, if the fund has elected into the reporting fund regime, gains are taxed as capital gains, and income distributions are taxed as dividends.

Most UCITS funds registered in Ireland or Luxembourg (the two dominant jurisdictions for UK-marketed funds) have obtained reporting fund status. However:

• US-domiciled ETFs (such as most iShares and SPDR funds in their US form) do not have reporting fund status for UK purposes. UK investors holding US ETFs in taxable accounts face income tax on gains — a significant disadvantage.
• UK UCITS ETFs (including London-listed versions of iShares, Vanguard, and others) typically do have reporting fund status.

Before investing in any non-UK fund through a taxable account (as opposed to an ISA or SIPP, where the distinction is irrelevant), confirm its UK reporting fund status on the HMRC Reporting Funds list, available on the HMRC website.

For most UK individual investors, this means that US-domiciled ETFs should generally be avoided in taxable accounts — use the equivalent UK-listed UCITS version instead.

Accumulation vs Income Units

Many UK-registered funds are available in both accumulation (Acc) and income (Inc) unit classes. In an accumulation fund, dividends are reinvested into additional units rather than paid out as cash.

However, for UK tax purposes, the underlying income is still treated as having been received — even if not physically distributed. These are known as notional distributions or excess reportable income for reporting funds. UK investors in accumulation units must declare this notional income annually, even though they received no cash payment. The HMRC reporting fund statements (published annually by fund managers) provide the relevant figures.
