Which Dividends Are Taxable?

Dividends from shares or funds held in a general investment account (GIA) outside an ISA or pension are subject to UK dividend tax. This includes dividends from UK-listed shares, international shares held via a UK brokerage, funds and ETFs that distribute income, and REITs (real estate investment trusts) that pay dividends. Dividends inside a Stocks and Shares ISA are completely exempt. Dividends inside a pension (SIPP) are not taxed at the personal level, though the pension fund may suffer irrecoverable withholding tax on foreign holdings.

The taxable total is the sum of all dividends received from non-ISA, non-pension holdings during the tax year, whether UK or foreign. This gross total is what you report on Self Assessment. The £500 dividend allowance then applies, and the remainder is taxed at 10.75%, 35.75% or 39.35% depending on which band the dividends fall into after your salary and other income has been allocated.

Worked Example: Basic-Rate Investor with Mixed Portfolio

An investor has a salary of £28,000 and receives the following dividends in 2026/27: £600 from UK equity income ETF held in a GIA, £400 from US S&P 500 fund held in a GIA (after 15% withholding, gross was £471), and £1,200 from a UK equity ISA. Total taxable dividends: £600 + £471 = £1,071 (ISA dividends are excluded). Withholding on the US fund: £71 (15% of £471).

Dividend allowance: £500 free. Taxable dividends: £571. Both the UK and US dividends fall within the basic-rate band (total income is well below £50,270 at £28,000 + £1,071 = £29,071). Setting the £500 allowance against the UK dividends first leaves £100 of UK dividends and the £471 US dividend taxable. UK tax on the US dividend at 10.75% is £50.63, fully covered by the £71 US withholding (the extra £20.37 is not refunded). UK tax on the remaining £100 of UK dividends is £10.75. Total UK dividend tax on the GIA investments: about £10.75. The ISA dividend of £1,200: zero tax.

This investor has a very small UK dividend tax bill once the US withholding is credited. Because total GIA dividends exceed £500 they must tell HMRC; claiming the foreign tax credit is done through Self Assessment. The form SA106 is needed for the foreign dividends.

Worked Example: Higher-Rate Investor, Larger Portfolio

An investor has a salary of £70,000 and holds £200,000 of dividend-yielding shares in a GIA, yielding 4% = £8,000 in dividends. Salary of £70,000 already exceeds the basic-rate limit, so all dividends fall in the higher-rate band.

Dividend allowance: £500 free. Taxable dividends: £7,500 at 35.75% = £2,681. The investor also holds £100,000 in a Stocks and Shares ISA yielding 4% = £4,000 in tax-free ISA dividends. If the entire £300,000 was in the GIA, dividend tax would be on £11,500 at 35.75% = £4,111. The ISA shelters £1,430 of annual dividend tax (35.75% × £4,000).

Over a 20-year investment period, the ISA dividends reinvested without tax compound significantly more than the same dividends taxed at 35.75% each year. Reinvesting £4,000 at 4% over 20 years with no tax versus reinvesting £2,650 (after 35.75% tax) over the same period produces a meaningful difference in terminal wealth, demonstrating why asset location (which assets go inside the ISA) matters for long-term portfolio returns.

Which Assets Belong in the ISA?

The ISA allowance is £20,000 per year per person. With a fixed annual limit, prioritisation matters. The general principle is to hold the highest-tax-drag investments inside the ISA first. For investors paying dividend tax at 35.75%, high-yield income investments (equity income funds, REITs, bond funds) create the largest annual tax drag and benefit most from ISA shelter. Growth investments with low dividend yields create less annual drag and can sit outside the ISA more comfortably.

However, growth assets with long holding periods create large eventual capital gains. The ISA eliminates CGT on these gains too. For very long-term holdings, the compounded CGT saving on growth assets inside an ISA can rival or exceed the dividend tax saving from income assets. Most financial planners suggest holding the highest total-return assets inside the ISA first, which often means high-dividend income funds for higher-rate taxpayers, and high-growth assets for basic-rate taxpayers whose dividend tax drag is modest.

Pension Contributions as a Dividend Tax Lever

For investors close to the higher-rate threshold (£50,270), pension contributions can shift dividend income from the 35.75% band back into the 10.75% band. A salary of £52,000 with £3,000 of dividends would normally have all dividends in the higher-rate band: the £500 allowance covers the first £500 and the other £2,500 is taxed at 35.75%, which is £893.75. A personal pension contribution of £4,730 (gross, paid with tax relief at source) extends the basic-rate band to £55,000 of income. The £2,500 of taxable dividends is then taxed at 10.75%, which is £268.75, saving £625 on the dividends. A smaller contribution, such as £2,000, does not move any of them: the salary takes £1,730 of the extra band and the £500 allowance uses the remaining £270.

The annual allowance for pension contributions in 2026/27 is £60,000 (subject to the tapered allowance for high earners). This gives most investors substantial scope to make contributions that both reduce dividend tax and build retirement savings. The pension contribution itself receives income tax relief, at 40% for higher-rate taxpayers, making the combined benefit of dividend tax reduction and contribution relief significant.
