CGT on property

Everything You Need to Know

Table of Contents

CGT on property is the tax you pay on the profit made when selling or transferring a UK property that has increased in value. It usually applies to second homes, buy-to-lets, or investment properties rather than your main residence. You must report and pay CGT within 60 days of completion, and reliefs such as Private Residence Relief or Lettings Relief can help reduce the tax payable. 

Understanding CGT on property is crucial if you’re selling, gifting, or transferring a property that’s increased in value. Whether you’re a homeowner, landlord, or investor, the rules can be complex – and getting them wrong could cost you. 

At Naail & Co Chartered Certified Accountants and Tax Advisors, we help clients calculate, report, and plan for Capital Gains Tax (CGT) on property efficiently and compliantly. Our team ensures you make the most of available reliefs and avoid unnecessary tax exposure. 

What Is CGT on Property?

CGT on property applies when you dispose of a property that has gained value since you bought it. The tax is based on the profit (the “gain”) you make – not the total sale price. 

You may need to pay CGT when you: 

  • Sell a residential property, second home, or buy-to-let. 
  • Gift property (other than to a spouse or civil partner). 
  • Transfer property into a company or trust. 
  • Exchange or otherwise dispose of your ownership. 

If the property is your main residence, you may qualify for Private Residence Relief, which can significantly reduce or even eliminate the tax. 

Property tax can be nuanced – a short discussion with our tax specialists at Naail & Co can help clarify your position and save you thousands in potential CGT. 

Who Pays CGT on Property?

You may need to pay CGT on property if you are: 

  • A UK resident selling or transferring a UK residential property that isn’t fully covered by Private Residence Relief. 
  • A non-UK resident disposing of any UK property or land (even commercial or mixed-use). 
  • Acting as a trustee, executor, or personal representative of an estate. 
  • A company selling an investment property (corporate CGT rules apply separately). 

Even if you live abroad, you may still have UK reporting obligations. Non-residents must report the sale of UK property to HMRC, even if there’s no gain or tax due. 

If you’re unsure about your residency status or reporting duties, our international tax team at Naail & Co can assess your situation and ensure full compliance. 

When and How to Report CGT on Property

Since 6 April 2020, individuals and trustees selling UK residential property must report and pay CGT within 60 days of completion. 

Failing to do so can lead to penalties and interest, even if the gain was small or reliefs applied. 

To meet your obligations, you must: 

  1. Calculate the gain accurately. 
  1. Create a Capital Gains Tax on UK Property Account via HMRC. 
  1. File the return and pay any tax within 60 days of completion. 

If you’ve already filed a Self-Assessment tax return, you still need to make this separate 60-day submission. 

Naail & Co can handle the entire process — from working out the gain to submitting the report to HMRC securely and on time. 

How to Calculate Your Gain: CGT on Property Step-by-Step

Calculating CGT on property involves several steps: 

  1. Identify your disposal proceeds – usually the sale price, or market value if transferred to someone connected to you. 
  1. Deduct allowable costs – purchase price, legal fees, stamp duty, estate agent costs, and capital improvements (extensions, new rooms, etc.). 
  1. Apply reliefs and allowances – such as Private Residence Relief, Lettings Relief, and the annual CGT allowance. 
  1. Work out your taxable gain – what remains after deductions and reliefs. 

Example: 
If you bought a second home for £200,000 and sold it for £500,000, your total gain is £300,000. After deducting £20,000 of allowable costs and your £3,000 annual exemption, you’d pay CGT on £277,000 at 18% or 24%, depending on your income level. 

Every property and taxpayer is different. Naail & Co’s specialists can calculate your exact CGT liability and identify potential tax-saving opportunities. 

Rates, Allowances and Reliefs for CGT on Property

CGT on property rates vary based on your income tax band and the type of property sold: 

  • 18% for basic rate taxpayers on residential property gains. 
  • 24% for higher and additional rate taxpayers. 

Key Reliefs and Allowances 

  • Annual Exempt Amount: £3,000 (2024/25 tax year). 
  • Private Residence Relief (PPR): May exempt you entirely if the property was your main home. 
  • Lettings Relief: Limited relief available if you once lived in the property but later rented it out. 
  • Spousal Transfers: Usually exempt from CGT and can help with tax planning. 

Reliefs can make a significant difference in your tax bill. The Naail & Co team can review your situation and advise on how best to apply these reliefs before you sell. 

Common Scenarios and CGT Traps

  1. Selling your main home: Normally exempt, but partial business or rental use could trigger CGT. 
  1. Selling a second home or buy-to-let: Usually fully chargeable to CGT. 
  1. Gifting property to children: Treated as a sale at market value for CGT purposes. 
  1. Selling through a company: Corporate CGT (Corporation Tax on chargeable gains) may apply. 
  1. Non-residents disposing of UK property: Must report to HMRC even if exempt or no gain. 

Avoiding simple errors—like missing the 60-day deadline or misunderstanding relief rules—can prevent HMRC enquiries and unnecessary penalties.

Planning Ahead: Reducing CGT on Property

There are legitimate ways to reduce or defer CGT on property, such as: 

  • Transferring ownership to a spouse before sale to utilise both allowances. 
  • Timing disposals across tax years for optimal tax positioning. 
  • Claiming any available reliefs and offsetting capital losses. 
  • Considering incorporation or restructuring if multiple properties are held. 

Effective planning can help you legally minimise your CGT bill and retain more of your profits. 
Naail & Co Chartered Certified Accountants can guide you through every step – from planning a future sale to structuring ownership efficiently.

🔹 12 SEO-Optimised FAQs – CGT on Property

CGT on property is the tax you pay on the profit made when selling, gifting, or transferring a property that has increased in value. It applies mainly to second homes, buy-to-lets, and investment properties, not usually your main residence. 

You calculate CGT on property by taking the sale price (or market value), deducting allowable costs such as the purchase price, legal fees, and improvements, and applying any reliefs or exemptions. The remaining gain is taxed at 18% or 24%, depending on your income level. 

 

If you sell or transfer a UK residential property that triggers a gain, you must report it to HMRC and pay any tax within 60 days of completion. This rule applies even if you also complete a Self-Assessment tax return later in the year. 

For the 2024/25 tax year, CGT on residential property is charged at 18% for basic rate taxpayers and 24% for higher or additional rate taxpayers. The rate depends on your total taxable income and the size of the gain. 

If your property has always been your main residence, it is generally exempt under Private Residence Relief. However, partial business use, letting, or long absences can reduce the exemption and trigger some CGT. 

Each individual has an annual CGT exemption of £3,000 for 2024/25. This amount can offset part of your property gain before tax is calculated. Couples can double this by owning property jointly. 

You can reduce CGT by using reliefs such as Private Residence Relief, Lettings Relief, or spousal transfers. Planning the timing of the sale or offsetting losses from other assets can also lower your tax bill. 

The team at Naail & Co can help you plan strategically before completing a sale. 

Gifting property (other than to a spouse) is treated as a disposal at market value, meaning CGT on property may apply even if you receive no money. You may also need to consider inheritance tax implications. 

Non-UK residents must report and pay CGT on disposals of UK land or property, including residential and commercial assets. Reporting must still be done within 60 days, regardless of whether tax is owed. 

You can deduct acquisition and disposal costs, including: 

  • Legal and conveyancing fees 
  • Estate agent and surveyor fees 
  • Stamp Duty Land Tax 
  • Capital improvements such as extensions or new rooms (but not maintenance or decoration) 

Companies do not pay CGT in the same way as individuals; instead, gains on property sales are subject to Corporation Tax on chargeable gains. Naail & Co can calculate and report this accurately for your company. 

Late filing or payment can lead to HMRC penalties and interest. If you’ve missed the deadline, contact Naail & Co immediately — we can help you file a late report, mitigate penalties, and manage HMRC correspondence.
