What is Capital Gains Tax?

Posted on Feb 20th, 2018 | Tax

Capital Gains Tax comes into play when you make a profit from selling something you own. The important point to remember is that the tax is calculated on the profit you make, and not the amount you sold it for. As the name suggests, it’s all about the gain!

So, Capital Gains Tax is essentially a tax on profits and it applies to most assets when they’re sold. There are some exceptions, however – for example your car, your main place of residence if you own your home, and personal possessions sold for £6,000 or under are all exempt. You don’t pay Capital Gains Tax when you sell your car, unless you use it for business. There are also some complex rules for assets with an expected life of under 50 years.


Capital Gains Tax also applies to assets received as gifts from other people (though not usually your spouse or civil partner). A valuation needs to be made of how much the asset is valued at when gifted, and if a gain is calculated, the tax is applied. There is tax relief available for gifts, so please speak with an accountant for more advice.


If you inherit an asset then you won’t have to pay Capital Gains Tax until you sell it – at which point you will need to know how much it was valued at the time you inherited so that you can calculate and if necessary report the gain on your tax return. It can be a good idea to keep a record of these assets so that if you ever do decide to sell, the process will be easier. This might also be useful in case you need to let your insurers know if it is particularly valuable.

How much can you currently gain before paying Capital Gains Tax?

For the tax year 2017/2018, you’re exempt from having to pay Capital Gains Tax on the sale of any assets if the profits made are less than £11,300. In the 2018/19 tax year the amount is £11,700. This is known as the annual tax-free allowance or the Annual Exempt Amount.

If you don’t already complete a Self Assessment you will need to register with HMRC by 5th October following the tax year in question to enable you to complete one.

Capital Gains Tax Rate

The following Capital Gains Tax rates apply for the tax years 2017/18 and 2018/19 (the tax rate you use depends on the total amount of your taxable income, so you need to work this out first):

  • 10% or 20% tax rates for individuals (not including residential property)
  • 18% or 28% tax rates for individuals for residential property and carried interest
  • 20% for trustees or for personal representatives of someone who has died (not including residential property)
