UK Tax on Investments Guide 2026/27

Dividend Tax in 2026/27

Dividends are payments made by companies to their shareholders from after-tax profits. In the UK, dividends receive a small annual allowance before tax kicks in, but the allowance has been cut dramatically since 2018.

For 2026/27, the first £500 of dividend income is tax-free regardless of your tax band. Dividends above £500 are taxed at:

• 10.75% if you are a basic-rate taxpayer (income below £50,270)
• 35.75% if you are a higher-rate taxpayer (income £50,271–£125,140)
• 39.35% if you are an additional-rate taxpayer (income above £125,140)

Dividends are stacked on top of other income for the purpose of determining your tax band. They fill the top of your income, so if your salary and other income already take you into the higher-rate band, your dividends will be taxed at 35.75% even if the dividend itself is a relatively small amount.

Dividends Inside an ISA: Zero Tax

Dividends received on shares or funds held inside a Stocks and Shares ISA are completely free of tax — the 10.75%/35.75% rates do not apply, and nothing needs to be declared on a Self Assessment return. This is why high-dividend shares and equity income funds are among the most valuable assets to hold inside an ISA wrapper.

Accumulation Funds and Equalisation

Income funds distribute dividends directly; accumulation funds automatically reinvest them. HMRC still treats reinvested amounts in accumulation funds as "deemed distributions" — you owe dividend tax even though no cash left the fund. Tracking equalisation (the interest element on accumulation units bought mid-way through a distribution period) is important and can make accumulation funds fiddly for taxable accounts. Inside an ISA or SIPP, this complexity disappears.

Capital Gains Tax on Investments

Capital Gains Tax (CGT) is payable when you dispose of an asset for more than you paid for it. Disposals include selling shares, redeeming fund units, transferring assets to someone other than a spouse or civil partner, and using assets as security on a loan that is subsequently called in.

The Annual Exempt Amount (AEA) for 2026/27 is £3,000. Net gains below this threshold — after deducting losses — are not taxable. Gains above £3,000 are taxed at:

Business Asset Disposal Relief (BADR)

BADR (formerly Entrepreneurs' Relief) reduces CGT on qualifying business asset disposals to a flat 18% rate. To qualify for shares in a trading company, you must hold at least 5% of ordinary shares, have been an employee or director for at least two years, and the company must be a trading company or holding company of a trading group. The lifetime limit is £1,000,000 of qualifying gains. BADR is only available outside of ISAs and SIPPs — but can save significant tax for founder-shareholders selling their business.

Capital Gains Inside an ISA: Zero Tax

Gains made on investments held inside a Stocks and Shares ISA are completely exempt from CGT. There is no need to track gains, apply the AEA or report anything. This is especially valuable for longer-term investors who expect significant appreciation — growth equity funds, smaller company shares and global index trackers are all strong candidates to shelter inside an ISA first.

Bond Income and the Savings Allowance

Interest from bonds — government gilts, corporate bonds and bond funds — is treated as savings interest, not dividends. It is taxed at your marginal income tax rate after applying the Personal Savings Allowance (PSA):

• Basic-rate taxpayer: £1,000 PSA — bond income up to £1,000 is tax-free
• Higher-rate taxpayer: £500 PSA — bond income above £500 taxed at 40%
• Additional-rate taxpayer: no PSA — all bond interest taxed at 45%

An additional benefit exists for those whose non-savings income (salary, rental income, etc.) falls below the Personal Allowance plus £5,000: they benefit from the starting rate for savings of 0% on up to £5,000 of savings and bond interest. This is most relevant for retirees with low employment income supplementing their income with bond fund distributions.

Crypto Tax in 2026/27

HMRC treats cryptocurrency as a capital asset. The key point is that almost any interaction with crypto is a taxable disposal:

• Selling crypto for GBP or another fiat currency — taxable gain or loss
• Trading one cryptocurrency for another — treated as disposal of the first asset; taxable
• Using crypto to buy goods or services — treated as a disposal at the market value at the time; taxable
• Gifting crypto (other than to a spouse) — taxable disposal at market value
• Staking rewards and mining income — usually treated as miscellaneous income, taxable at income tax rates when received

From January 2026, HMRC's Cryptoasset Reporting Framework (CARF) requires UK-based crypto exchanges to report user transaction data directly to HMRC. Combined with HMRC's existing cryptoasset compliance campaigns, the likelihood of undetected non-compliance is falling sharply. If you have unreported crypto gains from earlier years, HMRC's voluntary disclosure facility is the safest route to regularise your position before HMRC contacts you.

Overseas Investments and Foreign Tax Credit Relief

If you invest in overseas shares — US stocks, European equity funds, emerging market ETFs — you may face withholding tax in the country where the dividend originates. The US, for example, withholds 15% on dividends paid to UK investors (reduced from the standard 30% under the UK-US double tax treaty).

Foreign Tax Credit Relief (FTCR) prevents you from paying tax twice on the same income. You can credit the foreign withholding tax against your UK dividend tax liability on the same income. If the foreign withholding is higher than the UK liability, you cannot claim a refund — but you can avoid the full UK rate.

FTCR is claimed on the Foreign pages of your Self Assessment tax return. For most investors holding overseas funds inside an ISA, this is irrelevant — returns inside the ISA are tax-free and FTCR does not apply.

Practical Strategy: Tax-Efficient Asset Location

The single most impactful planning decision for UK investors is which assets to hold inside a tax wrapper (ISA/SIPP) versus in a general investment account (GIA). The principle: hold tax-inefficient assets inside the wrapper first.
