Capital Gains Tax (CGT) is a tax levied on the profit made from selling or disposing of certain assets that have increased in value. If you’re a resident or have property or business interests in the United Kingdom, it’s important to understand how CGT works. In this simple guide, we’ll explain the basics of UK Capital Gains Tax and provide you with an overview of key concepts and considerations.

  1. What is Capital Gains Tax? Capital Gains Tax is a tax on the profit (or gain) you make when you sell or dispose of an asset. It applies to various assets, including property, stocks and shares, business assets, and personal possessions worth more than £6,000 (known as “chattels”). The tax is calculated on the difference between the sale price and the original purchase price of the asset.
  2. Understanding the Annual Exempt Amount: Each tax year, you’re entitled to an annual exempt amount, which is the profit you can make from selling or disposing of assets without incurring Capital Gains Tax. As of the 2023-2024 tax year, the annual exempt amount for individuals is £6,000. Married couples and civil partners can combine their allowances, effectively doubling the exemption to £12,000.
  3. Tax Rates for Capital Gains: The tax rates for Capital Gains Tax depend on your income and the type of asset you’ve sold. As of the 2023-2024 tax year, the rates are as follows:
  • Basic rate taxpayers: 18% on gains from residential property and 10% on gains from other chargeable assets.
  • Higher and additional rate taxpayers: 28% on gains from residential property and 20% on gains from other chargeable assets. Note that the rates may be subject to change, so it’s important to consult the latest tax guidelines or seek professional advice.
  1. Reporting and Paying Capital Gains Tax: You’re responsible for reporting and paying Capital Gains Tax on any applicable gains. You must report your gains and losses on a Self Assessment tax return, even if you’re not required to file a return for other reasons. The deadline for filing your tax return and paying any CGT owed is generally January 31st following the end of the tax year in which the disposal occurred unless you have disposed of a residential property and then you have 60 days from disposal to report and pay any CGT due.
  2. Allowable Deductions and Losses: When calculating your Capital Gains Tax liability, you can deduct certain costs and losses from your gains. Allowable deductions may include acquisition costs (e.g., legal fees, surveyor fees), improvement costs, and selling costs (e.g., estate agent fees, legal fees). Additionally, if you’ve made losses from selling other assets, you can use them to offset any gains, reducing your overall tax liability.
  3. Special Rules and Reliefs: The UK tax system provides various special rules and reliefs that can help reduce your Capital Gains Tax liability. These include the following:
  • Principal Private Residence Relief (PPR): If you’re selling your main residence, PPR may exempt you from paying CGT or reduce the taxable gain.
  • Lettings Relief: If you’ve let out a property that was previously your main residence, you may be eligible for this relief, which can reduce your CGT liability.
  • Business Asset Disposal Relief: If you’re selling all or part of a business, Business Asset Disposal Relief may apply, offering a lower tax rate of 10% on qualifying gains.
  1. Seek Professional Advice: Capital Gains Tax can be complex, especially when dealing with unique circumstances or intricate tax rules. It’s advisable to consult a tax advisor or accountant who specializes in CGT to ensure you understand your obligations and take advantage of any available reliefs
