Step-by-Step Guide for Calculating Capital Gains Tax in the UK

In the United Kingdom, HMRC treats assets as taxable, meaning capital gains tax applies to profits from selling or disposing of assets. Here’s a comprehensive guide to calculating your capital gains tax obligations in 2024.

  • Purchase Price: Initial investment amount.
  • Sale Price: Amount received upon sale.
  • Total Annual Gains: Check if it exceeds the capital gains tax allowance (£6,000 for 2024).
  • Total Income: Used for determining applicable tax brackets.

1. Determine Your Tax-Free Allowance

For 2024, the annual Capital Gains Tax (CGT) allowance is £6,000. If your total gains are below this threshold, no CGT is owed.

2. Calculate Your Capital Gain or Loss

To calculate your capital gain:

  • Subtract the purchase price from the sale price of the assets.
  • If the sale price is higher, the result is a capital gain.
  • If the sale price is lower, the result is a capital loss.

3. Determine the Applicable Tax Bracket and Rate

In the UK, capital gains tax rates vary depending on your total income for the year:

  • Basic-rate taxpayers: Up to £50,270 – 10% on capital gains.
  • Higher-rate taxpayers: Over £50,270 – 20% on capital gains.

4. How to Use the Calculator for Each Scenario
