What is Capital Gains tax? 

Capital gains tax (CGT) is imposed on the profit made from the sale of certain types of assets, including stocks, real estate, and other investments. When you sell an asset for more than what you paid for it, the profit is considered a capital gain and is subject to tax. This tax can significantly affect your overall return on investment, making it crucial for investors to understand its implications. 

 Who Pays Capital Gains Tax? 

Typically, anyone who sells an asset at a profit is liable for capital gains tax. This includes individual investors, businesses, and even trusts that realise gains from the sale of capital assets. The rate at which capital gains are taxed can vary depending on several factors, including the length of time the asset was held. Often, assets held for more than a year are subject to lower long-term capital gains tax rates, while those sold within a year are taxed at higher short-term rates, which can be equivalent to ordinary income tax rates. 

 How Much is the Capital Gains Tax? 

In the UK, individuals, businesses, and trusts are all required to pay capital gains tax if they sell an asset and make a profit. This includes personal investors as well as companies selling capital assets. Each individual is entitled to an annual exempt amount, which for the 2023/2024 tax year is £6,000. Gains above this threshold are taxable. It’s important to keep track of your capital gains and losses throughout the tax year to ensure you’re accurately reporting any taxable amounts. 

Potential Changes in Tax Policy 

The rate of capital gains tax in the UK depends on your total taxable income. For basic rate taxpayers, the CGT rate is 10%, while higher and additional rate taxpayers are charged 20%. However, for residential property, the rates are higher—18% for basic rate taxpayers and 28% for higher and additional rate taxpayers. Understanding these rates and how they apply to your specific situation can help you manage your investments more effectively. 

There have been many signs in 2024 that Capital Gains tax will be one of the changes coming this October and an increase is expected.
