When Do You Pay Capital Gains Tax?

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 is added to your normal tax payment for the year you filled your taxes.

Capital Gains Tax is applied to the profit made from the sale or disposal of an asset that has increased in value. It is important to understand which assets are taxable, how to calculate the gain, and how to report and pay the tax to ensure compliance and avoid penalties. Always consider your annual tax-free allowance and seek professional advice if needed to manage your tax obligations effectively.

Here’s a detailed explanation of how CGT works, including when and how it applies.

Key Concepts of Capital Gains Tax          

  1. Tax on the Gain: CGT is levied on the profit (gain) you make from selling an asset, not on the total amount you receive from the sale.

    • Example: If you buy a painting for £5,000 and sell it later for £25,000, your gain is £20,000 (£25,000 - £5,000).

  2. Tax-Free Assets: Some assets are exempt from CGT, such as your primary residence, personal belongings sold for less than £6,000, and certain types of investments like ISAs (Individual Savings Accounts).

  3. Tax-Free Allowance: If your total gains in a tax year are below the annual tax-free allowance, you do not have to pay CGT. The allowance for the 2024/2025 tax year is £3,000.

Disposing of an Asset

Disposing of an asset can occur in various ways:

  • Selling It: The most common form of disposal.

  • Gifting or Transferring: Giving the asset away as a gift or transferring ownership to someone else.

  • Swapping: Exchanging the asset for something else.

  • Compensation: Receiving compensation, such as an insurance payout, if the asset is lost or destroyed.

Reporting and Paying CGT on UK Residential Property

If you sold a UK residential property on or after 6 April 2020 and have a gain to report, you must use a Capital Gains Tax on UK property account to report and pay the tax due. This must be done within 60 days of the sale.

Example Calculation

Scenario: Selling a Painting

  • Purchase Price: £5,000

  • Sale Price: £25,000

  • Gain: £25,000 - £5,000 = £20,000

If your annual gains are below the tax-free allowance, you do not owe CGT. However, if the gain exceeds the allowance, you need to report and pay CGT on the excess amount.

Steps to Calculate and Report CGT

  1. Determine the Gain: Subtract the acquisition cost and any allowable expenses (e.g., selling fees, improvement costs) from the sale price to determine the gain.

  2. Apply Tax-Free Allowance: Subtract your annual tax-free allowance from your total gains.

  3. Report the Gain: If the remaining gain is above the allowance, report it to HMRC.

  4. Pay the Tax: Calculate the CGT owed based on your tax rate and pay it within the required timeframe.

Additional Information

  • Assets Exempt from CGT: Certain assets are not subject to CGT, such as personal cars, your main home, and gifts to your spouse or civil partner.

  • Special Cases: Specific rules apply for assets like business properties and shares. For example, you may be eligible for Business Asset Disposal Relief, reducing the CGT rate on business assets.
