Owning rental properties can be a great way to generate income and build wealth. However, when it comes time to sell, understanding the tax implications is crucial. One of the key taxes landlords need to be aware of is capital gains tax (CGT). This tax applies to the profit made from selling a property that is not your main home. In this post, I will walk you through the essentials of capital gains tax on rental properties in the UK, helping you navigate this often complex area with confidence.


What You Need to Know About Property Tax on Rentals UK


When you sell a rental property, the government expects you to pay tax on the gain you make from the sale. This gain is the difference between the price you bought the property for and the price you sold it for, minus any allowable expenses. This is where capital gains tax comes into play.


The rate of CGT you pay depends on your total taxable income and the size of the gain. For basic rate taxpayers, the rate is 18%, and for higher or additional rate taxpayers, it is 28%. It’s important to note that these rates apply specifically to residential property gains.


Here are some key points to keep in mind:


  • Allowable costs: You can deduct certain costs from your gain, such as solicitor fees, estate agent fees, and costs of improvements (not repairs).

  • Annual exempt amount: Each individual has an annual tax-free allowance for capital gains. For the 2023/24 tax year, this is £6,000.

  • Reporting and payment: Since April 2020, you must report and pay any CGT on UK residential property within 60 days of completion.


Understanding these basics helps you plan better and avoid surprises when selling your rental property.

How to Calculate Capital Gains Tax on Rental Properties


Calculating CGT can seem daunting, but breaking it down step-by-step makes it manageable. Here’s how I approach it:


  1. Determine the sale price: This is the amount you sold the property for.

  2. Subtract the purchase price: The original price you paid for the property.

  3. Deduct allowable costs: Include costs like legal fees, estate agent fees, and any capital improvements.

  4. Apply the annual exempt amount: Deduct your tax-free allowance from the gain.

  5. Calculate the tax due: Apply the correct CGT rate based on your income tax band.


For example, if you bought a rental property for £200,000 and sold it for £300,000, your gain is £100,000. If you spent £10,000 on improvements and paid £5,000 in fees, your taxable gain would be £85,000 (£100,000 - £10,000 - £5,000). After deducting the £6,000 exemption, you would pay CGT on £79,000.


If you are a higher-rate taxpayer, the tax due would be 28% of £79,000, which is £22,120.


It’s also worth noting that if you own the property jointly, each owner can use their annual exemption, potentially reducing the tax bill further.


What is the 6-year rule for capital gains tax in the UK?


One important relief to be aware of is the 6-year rule, which can reduce your CGT liability if you lived in the property at some point. This rule applies when you have used the property as your main residence but later rented it out.


Here’s how it works:


  • You can claim private residence relief for the time you lived in the property.

  • Additionally, the last 6 years of ownership are treated as if you lived there, even if you were renting it out.

  • This means you won’t pay CGT on the gain attributable to those final 6 years.


For example, if you lived in a house for 4 years, then rented it out for 8 years before selling, you can claim relief for the 4 years you lived there plus the last 6 years. So, 10 years of your 12-year ownership period could be exempt from CGT.


This rule can significantly reduce your tax bill, especially if you rented out your former home for a long time before selling.

Tips to Minimize Capital Gains Tax on Rental Properties


There are several strategies you can use to reduce your CGT liability legally:


  • Use your annual exemption: Make sure to use your tax-free allowance each year.

  • Transfer ownership to a spouse or civil partner: Transfers between spouses are exempt from CGT, allowing you to use both exemptions.

  • Keep good records: Track all allowable expenses and improvements to maximize deductions.

  • Consider timing: If possible, plan the sale in a tax year when your income is lower to benefit from a lower CGT rate.

  • Claim lettings relief: If you lived in the property and rented it out, lettings relief may reduce your gain further (up to £40,000).


Always consult with a tax professional to ensure you are applying these strategies correctly and in line with current tax laws.


Reporting Capital Gains Tax on Rental Properties


Since April 2020, the UK government requires landlords to report and pay CGT on residential property sales within 60 days of completion. This is a change from the previous system, where CGT was reported through the self-assessment tax return.


Here’s what you need to do:


  • Calculate your gain: Use the steps outlined earlier.

  • Report the gain online: Use the HMRC property disposal service.

  • Pay the tax: The payment deadline is 60 days after the completion date.


Failing to report and pay on time can result in penalties and interest charges, so it’s important to stay on top of deadlines.
