Understanding capital gains tax

Understanding capital gains tax: A guide for UK taxpayers

Capital Gains Tax (CGT) is a critical area of UK tax legislation that individuals and businesses must understand to effectively manage their financial affairs. Whether you’re selling an investment property, disposing of shares, or cashing in on the value of your business, CGT can have a significant impact. This guide will break down the essentials of CGT to help you stay compliant and maximise your tax efficiency.

What is Capital Gains Tax?

Capital Gains Tax is a tax on the profit (or gain) you make when you sell or dispose of an asset that has increased in value. It’s important to note that CGT is not charged on the total amount you receive, but on the gain you make from the transaction. For example:

If you bought an asset for £50,000 and sold it for £80,000, your taxable gain is £30,000.

CGT applies to various assets, including (but not limited to):

Investment properties
Shares
Business assets
Personal possessions worth over £6,000 (excluding your car)

CGT Rates pre-30 October 2024

The rate of CGT you’ll pay depends on the type of asset and your income tax band:

Basic-rate taxpayers:
- 10% on most gains, including non-residential property
- 18% on gains from residential property
Higher or additional-rate taxpayers:
- 20% on most gains, including non-residential property
- 24% on gains from residential property

CGT Rates from 30 October 2024

The rate of CGT you’ll pay remains based on your income tax bands, but have increased for most gains and are as follows:

Basic-rate taxpayers:
- 18% on all gains, including residential & non-residential property
Higher or additional-rate taxpayers:
- 24% on all gains, including residential & non-residential property

Business Asset Disposal Relief (BADR)

This relief covers certain gains subject to a lifetime limit of £1m. BADR will be limited for the 2025/26 tax year, and again for the 2026/27 tax year, as follows:

Pre-6 April 2025 – 10%
From 6 April 2025 – 14%
From 6 April 2026 – 18%

Exemptions and Allowances

For the 2025/26 tax year, individuals benefit from a CGT annual exemption of £3,000 (£6,000 for couples who jointly own assets). Gains within this allowance are not taxed. It’s worth noting that this allowance has been reduced from previous years, making strategic tax planning even more essential.

Key Considerations for Businesses

If you own a business or are selling business assets, you may be eligible for certain reliefs to reduce your CGT liability. These include:

Business Asset Disposal Relief (BADR): Previously known as Entrepreneurs’ Relief, this allows you to pay a reduced rate of 10% on qualifying gains, up to a lifetime limit of £1 million, as mentioned above these rates change from 6 April 2025.
Incorporation Relief: If you transfer your business to a company in exchange for shares, you can defer paying CGT on the gain.

How to Report and Pay CGT

You must report taxable gains to HMRC by completing a Self Assessment tax return or using the “real-time” Capital Gains Tax service. Residential property gains must be reported and paid within 60 days of the sale.

Failing to report gains accurately or on time can result in penalties and interest charges, so it’s essential to stay organised.

Strategies to Reduce Your CGT Liability

Use your annual exemption: Ensure gains are within the tax-free threshold.
Offset losses: Capital losses can be used to reduce your taxable gains.
Plan disposals strategically: Spread sales over multiple tax years to utilise multiple annual exemptions.
Transfer assets to a spouse: Spouses and civil partners can transfer assets tax-free and benefit from their own CGT allowances.
Claim available reliefs: Ensure you’re claiming BADR or other reliefs where applicable.

 Trustindex verifies that the original source of the review is Google. I cannot recommend Neil and Munro Bowman highly enough. I have worked with Neil for a long time across different accounting firms, and his support has been unwavering through the management of various limited companies and my self-assessment tax returns. Recently, when I needed to navigate some complex business decisions, Neil went completely above and beyond. Not only did he take the time to consult with other directors in the firm to ensure I had the most comprehensive advice, but he also connected me with exactly the right external specialists. His professionalism, reliability, and genuine care for his clients give me complete peace of mind. An absolutely stellar service!

 Trustindex verifies that the original source of the review is Google. Until I set up my own corporate advisory firm 12 years ago I'd enjoyed the luxury of a full range of accounting services that you rely on in an international consultancy.  I "bumped into" Neil Kellaway online and I have stayed with him following him from firm to firm as his career progressed.  That fact relies on my experience of prompt reliable service which I cannot fault.  Nothing changed throughout the pandemic.  Nothing changed when things went wrong at his end.   And he always made me feel smarter at finical matters than I really am.   What more can i say.
