Capital Gains Tax Calculator — United Kingdom

How United Kingdom Capital Gains Tax Works

The United Kingdom's capital gains tax (CGT) system is designed to tax the profit made from the disposal of certain assets, such as property, shares, and investments. For the 2023-2024 tax year, the CGT rates are as follows: 10% for basic-rate taxpayers and 20% for higher-rate taxpayers. An additional 8% surcharge applies to gains from residential property, making the rates 18% and 28% respectively.

How to Use This Calculator

This calculator is designed to help you estimate your CGT liability in the United Kingdom. To use it, you'll need to input the following information:

• The acquisition cost of the asset
• The disposal proceeds (the amount you sold the asset for)
• The amount of any losses you've incurred in the current tax year
• Your income tax rate (basic or higher)

For example, let's say you bought a property in London for £200,000 in 2010 and sold it for £350,000 in 2023. You've also made a loss of £10,000 on another investment in the same tax year. Using this calculator, you would input the acquisition cost (£200,000), the disposal proceeds (£350,000), the loss (£10,000), and your income tax rate (e.g., higher rate). The calculator would then estimate your CGT liability.
