Foreign Dividend Tax UK 2026/27, Double Taxation, Withholding Tax and How to Declare

UK Tax on Foreign Dividends, Same Rates as UK Dividends

If you hold shares in overseas companies, whether directly, via an investment platform, or through a fund, any dividends you receive are subject to UK income tax in exactly the same way as dividends from UK companies. For 2026/27 the rates are: 8.75% on dividends within the basic-rate band (total income up to £50,270), 33.75% in the higher-rate band (£50,271 to £125,140), and 39.35% in the additional-rate band (above £125,140). The £500 dividend allowance applies to your total dividends, UK and foreign combined, not separately to each type.

This means a UK investor receiving £300 in UK dividends and £400 in US dividends has £700 of total dividend income. After the £500 allowance, £200 is taxable at the applicable rate. HMRC does not distinguish between UK-sourced and foreign-sourced dividends in setting the rate, they all sit in the same pot.

Withholding Tax, What It Is and Why It Matters

Most countries deduct a withholding tax from dividends before paying them to overseas investors. This means you receive less than the gross dividend. The withholding rate depends on the country and whether a double taxation agreement (DTA) exists between that country and the UK. Without a DTA, the withholding rate can be 25–35%. With a DTA, it is usually lower.

Common withholding rates for UK investors in 2026/27: United States, 15% under the UK-US tax treaty (standard rate is 30%, but the treaty reduces this to 15% for most UK investors); Germany, 15% under treaty; France, 12.8% under treaty; Ireland, 0% (no withholding on dividends to UK investors under the UK-Ireland treaty); Netherlands, 15% under treaty. Note that some countries have higher effective rates for certain investor types or fund structures. Always check your broker statement for the actual amount withheld.

Double Taxation Relief, Offsetting Withholding Tax Against UK Tax

The UK has double taxation agreements with more than 130 countries. These agreements allow you to offset the withholding tax you have already paid abroad against the UK dividend tax you would otherwise owe. This prevents the same income from being taxed twice in full.

The relief works as follows: you declare the gross foreign dividend (before withholding) on your Self Assessment return and calculate the UK dividend tax due at the applicable UK rate. You then claim credit for the withholding tax paid, reducing the UK tax bill accordingly. The credit is capped at the UK tax that would otherwise be due, you cannot receive a repayment if the withholding tax exceeds your UK liability.

Example: You receive a US dividend with a gross amount of £1,000. The broker withholds 15% = £150, so you receive £850. Your UK dividend tax on £1,000 at the basic rate (8.75%) = £87.50. The foreign tax credit is capped at £87.50, so you have no additional UK tax to pay, but the excess £62.50 of US withholding is not refunded. For a higher-rate taxpayer, the picture is different: UK tax at 33.75% on £1,000 = £337.50; withholding credit of £150; additional UK tax due = £187.50.

How to Declare Foreign Dividends on Self Assessment

Foreign dividends are reported in the 'Foreign income' section of the Self Assessment return, using the SA106 supplementary pages (not the UK dividend section). You must enter the gross dividend amount received in each country, the amount of withholding tax deducted, and claim the foreign tax credit. HMRC requires you to convert foreign currency amounts to pounds sterling using the exchange rate at the date of receipt (or an average rate for the year, which HMRC publishes).

Your broker or investment platform should provide a consolidated tax certificate or annual summary showing: the gross dividends paid from each country, the withholding tax deducted, and the net amount received. This is the source document for your Self Assessment return. If your platform does not break down dividends by country, you may need to obtain this information from individual dividend vouchers or the company's investor relations page.

The filing deadline is 31 January following the end of the tax year. For 2026/27 (ending 5 April 2027), the deadline is 31 January 2028. You must pay any UK tax due by the same date. Interest accrues on late payments from that date.

Foreign Dividends Inside an ISA or SIPP

If you hold overseas shares or international funds inside a Stocks and Shares ISA or a pension (SIPP), UK dividend tax is not charged, the ISA and SIPP wrappers exempt you from UK tax regardless of the dividend source. However, withholding tax at source is a different matter: the foreign country still withholds tax before the dividend reaches your account, and in most cases this withholding cannot be reclaimed inside an ISA or SIPP wrapper (because there is no UK tax liability against which to claim the credit).

This is an important but often overlooked point. A UK investor holding US shares inside an ISA pays no UK dividend tax, but will typically still suffer the 15% US withholding tax and cannot claim it back. For US equities specifically, some platforms offer W-8BEN form filing which reduces the US withholding to 15% (from 30%) but cannot eliminate it entirely for ISA holders. This makes US dividend stocks slightly less tax-efficient inside an ISA than domestic income stocks, where no withholding applies.
