Investment Tax Explained: Capital Gains Tax and Dividend Tax in the UK

Capital gains tax (CGT) may apply when an investment is sold for a profit.

This usually occurs when assets such as shares, funds or property investments are sold at a higher price than the original purchase cost.

The taxable gain is typically the difference between:

• The purchase price
• The sale price

However, individuals usually receive a capital gains tax allowance each tax year.

If gains exceed this allowance, the remaining amount may be taxed depending on the investor's income tax band.

Full details of capital gains tax rules are available from HMRC: gov.uk

Dividend income is another way investments can generate returns.

Dividends are payments made by companies to shareholders, usually from company profits.

In the UK, dividend income may be taxed if it exceeds the annual dividend allowance.

Dividend tax rates vary depending on the investor's income tax band.

Because dividend tax can affect investment returns, some investors choose to hold dividend-producing investments within tax-efficient accounts.

The UK tax system includes several allowances that may reduce the amount of tax paid on investments.

These include:

• Capital gains tax allowance
• Dividend allowance
• ISA allowance

These allowances can change over time depending on government policy.

For example, the government periodically reviews tax thresholds and allowances as part of fiscal policy.

Because of this, investors sometimes review their financial arrangements periodically.

Certain accounts may help reduce investment tax exposure.

Examples include:

• Stocks and Shares ISAs
• Pensions
• Junior ISAs

Investments held inside these accounts may benefit from favourable tax treatment.

For example, investments inside an ISA are generally free from capital gains tax and dividend tax.

Investment Tax and Financial Planning

Tax considerations can play an important role in long-term financial planning.

For example, investors often consider how different accounts may work together, such as holding some investments within ISAs and others within pensions.

Our article on tax efficient investing in the UK explains how these accounts are often used together when structuring investment portfolios.

Pensions may also play an important role in tax planning because contributions usually receive tax relief. Our article on pension tax planning explained explores how pension tax rules work in more detail.
