Capital Gains Tax Calculator - Quickly Workout Your CGT

Capital Gains Tax (CGT) is a tax you pay on the profit you make when you sell or dispose of an asset that has increased in value. Whether it’s property, shares, or cryptocurrency, understanding your CGT liability is crucial to avoid unexpected tax bills. Calculating this tax can be tricky due to varying rates and allowances. That’s where Capital Gains Tax Calculator comes in. It simplifies the process, giving you accurate estimates in just a few clicks. This guide will help you understand how the calculator works, the types of assets subject to CGT, and how to use the tool effectively.

What is Capital Gains Tax?

Capital Gains Tax is applied to the profit, or "gain," you make when selling an asset that has increased in value. It’s important to note that you only pay tax on the profit, not the total amount you receive from the sale. For instance, if you bought an asset for £10,000 and sold it for £15,000, your gain would be £5,000, and CGT would be calculated on this £5,000.

In the UK, different rules apply to various types of assets. CGT usually applies to:

• Property: This includes any property that is not your main residence, such as buy-to-let properties or second homes.
• Shares and Investments: Stocks, shares, and investment funds not held within tax-free accounts like ISAs.
• Cryptocurrency: Bitcoin, Ethereum, and other digital assets are also subject to CGT when you sell them for a profit.
• Valuable personal items (worth over £3,000, except cars)

The tax rate you’ll pay depends on your taxable income and the type of asset sold. Let’s break down the different rates and allowances to get a clearer picture.

UK Capital Gains Tax Rates and AllowancesTax-Free CGT Allowance 2024/25

Every individual has a tax-free allowance called the Annual Exempt Amount. For the 2024/25 tax year, it is £3,000. This means you won’t pay tax on the first £3,000 of gains. However, anything above this amount is subject to CGT.

CGT Rates for 2024/25 Tax Year

The rates vary based on the type of asset and your income tax band:

For Basic Rate Taxpayers:

• 10% on gains from shares and investments
• 18% on gains from property

For Higher and Additional Rate Taxpayers:

• 20% on gains from shares and investments
• 28% on gains from property

Example: If you’re a higher rate taxpayer and you make a gain of £20,000 on a property, your CGT liability would be calculated as follows:

• 20,000 (gain) — £3,000 (annual allowance) = £17,000 (taxable gain)
• 17,000 x 28% = £4,760 (CGT payable)

How the Capital Gains Tax Calculator Works

Our calculator is designed to give you quick and accurate estimates of your Capital Gains Tax. Here’s a step-by-step guide on how to use it:

Step 1: Select the Asset Type

Choose the type of asset you’ve sold. The options include investment (such as shares, stocks, or crypto) or property. Each asset type has different rules for tax calculation, so it’s crucial to select the right one.

Step 2: Choose the Tax Year

Next, select the tax year in which you made the profit. CGT rates and allowances can change yearly, so it’s essential to use the correct period to get an accurate estimate.

Step 3: Input Profits from Capital Gains

Use the slider or input box to enter the profit you made from the sale. This figure is the difference between the purchase price and the sale price after deducting any allowable expenses, such as renovation costs for property or broker fees for investments.

Step 4: Enter Your Salary and Other Income

Your total income, including your salary, affects the tax rate applied to your capital gains. Enter your annual salary and any other taxable income you received during the same tax year. This information helps the calculator determine whether your gains will be taxed at the basic or higher rate.

Step 5: See the Calculated CGT

After entering all the details, the calculator will show you three key pieces of information:

• Net Profit After Tax: The amount of profit you’ll keep after paying CGT.
• Estimated CGT Payable: An estimate of how much Capital Gains Tax you owe based on your total profit and income.
• Capital Gains Allowance: Your tax-free allowance for the year, which is deducted from your total gain before tax is calculated.

Tips for Reducing Your Capital Gains Tax

1. Utilize Your Allowance: Make sure to use your annual tax-free allowance. If your gains are close to the limit, consider selling assets over multiple tax years.
2. Claim Available Reliefs: Reliefs like Private Residence Relief or Entrepreneurs’ Relief can significantly reduce your tax bill. Ensure you know what you’re entitled to claim.
3. Offset Losses Against Gains: If you’ve made a loss on other assets in the same tax year, you can use these losses to offset your gains, reducing your CGT liability.
4. Consider Transferring Assets to a Spouse: Transfers between spouses are exempt from CGT, so you can split your assets to take advantage of both your allowances.
