You pay capital gains tax on the gain when you sell (or ‘dispose of’):

• Most personal possessions worth £6,000 or more, apart from your car, property that is not your main home
• Your main home if you have let it out, used it for business or it is very large
• Shares that are not in an ISA or PEP
• Business assets

These are known as ‘chargeable assets’ and you only pay CGT if your total gain is above the annual CGT exempt allowance.

No-one individual is exempt from paying CGT. However, there are instances when CGT does not apply:

• You do not pay CGT on gifts to a husband, wife, civil partner, or a charity. However, if you gift an asset to a spouse or civil partner, they may have CGT upon disposal at a later date
• No CGT is payable on death – Inheritance tax is assessed at that point. However, CGT can later apply if an inherited asset is then sold
• Gains on ISAs, PEPs and pensions are exempt.
• As are lottery winnings and betting winnings.
• Also, UK Gilts and premium bonds are exempt

If you are a higher rate taxpayer then you will pay 28% CGT on property sales (residential) and 20% on other assets. If you are a basic rate taxpayer, the rate you pay depends on the size of your gain, your taxable income and whether your gain is from residential property or other assets.

1. Work out how much taxable income you have - this is your income minus your personal allowance and any other income tax relief you are entitled to.
2. Work out your total taxable gains.
3. Deduct your tax-free allowance from your total taxable gains.
4. Add this amount to your taxable income.
5. If this amount is within the basic income tax band, you will pay 10% on your gains (or 18% on residential property). You will pay 20% (or 28% on residential property) on any amount above the basic tax rate.

If you are a Trustee or business, then the same rules apply as if you were a higher rate tax payer.

You do not have to pay tax if your total taxable gains are under your capital gains tax allowance. You still need to report your gains in your tax return if both of the following apply:

• The total amount you sold the assets for was more than 4 times your allowance
• You are registered for Self Assessment

If you fail to report in time, then you may be liable to a late filing fine. You must contact HMRC if unsure.

The following table provides the timeframes for declaring and paying CGT:

*Capital gains tax for non-residents may not apply to the whole gain. If not, you may have to pay more tax if you return to the UK after a period of temporary non-residence.

If you sold a residential property in the UK after 6 April 2020 then you have to report and pay CGT within 30 days of sale. This does not apply to properties that you have lived in for the entire time you owned it. Even if you have rented the property out at some point in the past, there are certain exemptions available, including the discounting of certain years your lived and owned the property.

Remember, it’s only the “gains” that are taxed and you’ve also got a £12,300 capital gains tax-free allowance, and any costs involved in selling the property are discounted as well. So, let’s say the property was valued at £250,000 at the time you inherited it, but it’s increased in value to £300,000 when you come to sell it, and you pay £5,000 in costs. You’ll therefore pay capital gains tax on £32,700 (the £50,000 profit minus the £5,000 costs and £12,300 tax-free allowance).

The actual amount of tax you’ll pay will vary depending on your tax bracket – if you’re a higher or additional rate taxpayer, capital gains tax is charged at 28% on residential properties, while for basic rate taxpayers, the rate paid depends on your income and the size of the gain (18% if your taxable gains plus taxable income falls within the basic income tax band, and 28% on any amount above it).

This is a complex area, and you should speak to an Accountant when dealing with the sale of a rental or partly rented property.
