Understanding Capital Gains Tax on Property in the UK

Navigating the intricacies of Capital Gains Tax (CGT) on property can feel daunting. This comprehensive guide will break down what CGT is, how it impacts property sales, and strategies to reduce your tax liability. Let's dive in!

What is Capital Gains Tax?

Capital Gains Tax is a tax you pay on the profit when you sell an asset that has increased in value. This applies to assets like stocks, valuable collectables, and property. For property specifically, CGT usually comes into play when selling a property that isn't your main residence, such as a buy-to-let property or a holiday home.

How Much is Capital Gains Tax on Property?

The CGT rate on property is higher than for other assets. For basic rate taxpayers, the rate is 18%, while higher and additional rate taxpayers pay 28%. The amount you owe depends on your total taxable income and the gain from the property sale.

To calculate your gain:

  1. Subtract the purchase price from the selling price.
  2. Deduct any allowable costs such as improvements, estate agent fees, and legal expenses.
  3. Apply the annual tax-free allowance, which is £12,300 for the 2020-2021 tax year.

For example, if you make a £30,000 gain on your property, you subtract the allowance, leaving £17,700 subject to CGT.

Other Conditions to Be Aware Of

Several factors can complicate your CGT calculations:

  • Primary Residence: If the property was your main home at any point, you can claim Private Residence Relief for the time you lived there, plus the last 9 months of ownership.
  • Large Gardens: If you sell part of your garden, CGT might apply if the total area exceeds 5,000 square meters.
  • Business Use: Using part of your property exclusively for business purposes can affect your CGT liability.
  • Purpose of Purchase: If you bought the property to renovate and sell at a profit, this might be treated differently for tax purposes.

Always consult with a financial advisor or tax professional to understand your specific situation.

Do I Have to Pay Capital Gains Tax on an Inherited Property?

When you inherit property, CGT is based on the property's market value at the time of the original owner's death. If you later sell the property, the gain is calculated from this market value. It's essential to get an accurate probate valuation to ensure correct tax calculations.

When Do You Pay Capital Gains Tax on Property?

You must pay CGT within 30 days of completing the sale or disposal of your property. This includes selling, gifting, or transferring ownership. Payments are made through a 'Residential Property Return' submitted to HMRC.

What Happens If I Don’t Pay?

Failing to declare and pay CGT can result in severe penalties, including fines up to double the amount owed. It's crucial to report and pay your CGT promptly to avoid legal troubles.

Avoiding Capital Gains Tax on UK Property

While you can't completely escape CGT, there are strategies to minimize it:

  • Partner Allowance: Married couples and civil partners can combine their tax-free allowances.
  • Unmarried Partners Nomination: Unmarried partners can nominate separate properties as their main residences.
  • Offsetting Previous Losses: Losses from other asset sales can offset future gains, reducing CGT liability.
  • Timing Your Sale: If you’ve used your allowance for the year, consider delaying the sale to the next tax year to utilize the new allowance.


1. What expenses can I deduct when calculating my gain?

  • You can deduct costs related to improving the property, estate agent fees, legal fees, and Stamp Duty.

2. How do I report a property sale to HMRC?

  • Use the 'Residential Property Return' on the HMRC website and pay any owed CGT within 30 days of the sale.

3. Can I reduce my CGT by living in the property before selling?

  • Yes, living in the property and making it your main residence can significantly reduce your CGT through Private Residence Relief.

By knowing the rates, exemptions, and allowable deductions, you can better prepare for any tax liabilities and potentially reduce the amount you owe.
