Capital gains tax rates have increased significantly, while the annual exemption remains at just £3,000. Smart planning can help minimize your tax bill through timing, spousal transfers, and using available reliefs.

For 2025/26, individuals are entitled to an annual CGT exemption of £3,000 and trustees up to £1,500.

The main rates of Capital Gains Tax increased from 10% and 20% to 18% and 24% respectively for disposals made on or after 30 October 2025.

Capital gain tax planning

When selling investments costs more than expected, capital gains tax has become much more expensive since rates increased and the annual exemption dropped from £12,300 to just £3,000. Many investors are caught off guard by large tax bills when selling shares, property, or other assets. Proper planning can help you time disposals and use available reliefs effectively.

Types of capital gains tax rates and reliefs available

  • Main rates of 18% for basic rate taxpayers and 24% for higher rate taxpayers
  • Residential property rates remain at 18% and 24% depending on your income level
  • Business Asset Disposal Relief at 14% rising to 18% from April 2026
  • Investors' Relief at 14% rising to 18% from April 2026
  • Annual exemption of £3,000 per person that cannot be carried forward
  • Spousal transfers at no gain/no loss to maximize both annual exemptions

From 30 October 2024, main CGT rates increased to 18% for basic rate taxpayers and 24% for higher rate taxpayers. Your rate depends on your total income including the capital gain.

Each person gets £3,000 tax-free capital gains per year. This exemption cannot be carried forward, so it's important to use it each year where possible through careful timing of disposals.

Previously called Entrepreneurs' Relief, this provides a reduced rate of 14% (rising to 18% from April 2026) on qualifying business disposals, subject to a lifetime limit of £1 million.

Strategic timing of asset disposals can help spread gains across tax years to make best use of annual exemptions and potentially keep you in lower tax bands.

Common capital gains tax planning strategies

HM Revenue and Customs practice and the law relating to taxation are complex and subject to individual circumstances and changes which cannot be foreseen.


An ISA is a medium to long term investment, which aims to increase the value of the money you invest for growth or income or both. The value of your investments and any income from them can fall as well as rise. You may not get back the amount you invested.
