Capital Gains Tax in the UK - A Complete Guide

Capital Gains Tax (CGT) is a tax on the profit you make when you sell or dispose of an asset that has increased in value. It can apply to a variety of assets, including property, shares, cryptocurrencies, and valuable personal items. Understanding Capital Gains Tax is essential for UK taxpayers, as it ensures you remain compliant with tax regulations and avoid any unnecessary penalties.

In this guide, we'll walk you through everything you need to know about CGT, including how it works, when it applies, the rates for the 2024/25 tax year, how to calculate your tax, and the best strategies for reducing your CGT liability.

What Is Capital Gains Tax?

Capital Gains Tax is charged on the profit made when you sell or dispose of assets that have increased in value. The gain is the difference between the price you paid for the asset (its 'base cost') and the price you sell it for. For example, if you bought a house for £200,000 and later sold it for £300,000, your gain would be £100,000, and you would be liable to pay CGT on that amount, minus any applicable allowances or deductions.

CGT doesn’t apply to the full amount you receive from selling the asset, only to the profit or "gain" that you make.

When Does Capital Gains Tax Apply?

You may need to pay CGT when you dispose of certain types of assets. Some common scenarios include:

1. Selling Property: If you sell a second home, a rental property, or a property that isn’t your primary residence, you may be liable for CGT on any profit made. Your main home is typically exempt due to Private Residence Relief, but there are exceptions.

2. Selling Shares: If you sell shares for more than you paid for them, the profit is subject to CGT.

3. Cryptocurrency Gains: Profit made from selling or exchanging cryptocurrency like Bitcoin is subject to CGT.

4. Selling Valuable Items: Certain personal belongings, such as artwork or jewellery, can also be subject to CGT if they increase in value and you sell them.

Capital Gains Tax Exemptions

While CGT applies to many assets, there are some exemptions to be aware of:

1. Main Residence Relief: Your primary home is generally exempt from CGT under Private Residence Relief, provided certain conditions are met (e.g., you lived in the property as your main home throughout the time you owned it).

2. ISAs: Any profit made on investments held in an Individual Savings Account (ISA) is not subject to CGT.

3. Government Bonds: The sale of UK government bonds, such as Premium Bonds, is generally free from CGT.

4. Personal Belongings: Items such as personal cars, clothing, and household goods are exempt from CGT, as long as they’re worth less than £6,000 each.

Capital Gains Tax Rates for 2024/25

The rates of Capital Gains Tax vary depending on the type of asset and the amount of gain you make. For the 2024/25 tax year, the key rates are:

• 18% for basic rate taxpayers
• 24% for higher rate and additional rate taxpayers

However, if you are a higher or additional rate taxpayer, the CGT rates on residential property and carried interest (from managing an investment fund) will differ:

• 24% for residential property gains
• 28% for carried interest gains
• 24% for other assets

How to Calculate Your Capital Gains Tax

Calculating CGT can seem complicated, but breaking it down step by step makes it more manageable. Here’s a simple guide to calculating your Capital Gains Tax:

1. Determine the Sale Price: This is the amount you received for selling the asset.

2. Deduct the Purchase Price: The amount you originally paid for the asset. This is also called the ‘base cost.’

3. Account for Allowable Costs: Deduct any costs directly related to the purchase and sale of the asset, such as legal fees, broker fees, and renovation costs for property.

4. Subtract the Annual Exempt Amount: For the 2024/25 tax year, you can make up to £3,000 in capital gains without paying tax. If you're married or in a civil partnership, you can combine your allowances to reduce the taxable gain.

5. Apply the CGT Rate: Once you’ve calculated your taxable gain, apply the appropriate CGT rate depending on your income level and the asset type.

You must report any taxable capital gains on your self-assessment tax return. For most people, the deadline for submitting your return is 31 January following the end of the tax year in which the gains were made.

If you have made a gain from the sale of residential property, you must report and pay the tax within 60 days of the sale.

Failure to report your CGT or pay it on time can result in penalties and interest, so it’s crucial to meet these deadlines.

Capital Gains Tax can be complex, with different rates, exemptions, and allowances to consider. To ensure you comply with tax regulations and optimise your tax position, it’s always a good idea to seek professional advice.

A personal tax accountant can help you understand the complexity of CGT, identify opportunities for tax planning, and ensure you only pay the tax you owe. By working with an expert, you can confidently manage your investments and reduce your overall tax liability.
