When selling your home in the UK, most homeowners don’t pay any tax on the proceeds thanks to Private Residence Relief, but there are specific circumstances where Capital Gains Tax might apply-including if you’ve rented the property, used it for business, or it’s not your main residence. According to recent HMRC data, approximately 1.2 million residential property transactions occur annually in the UK, with only about 15% resulting in Capital Gains Tax liabilities, primarily affecting those with multiple properties or those who haven’t used the property as their main home continuously.

Do You Pay Tax When You Sell Your House in the UK?
The tax situation when selling residential property can be straightforward for most homeowners but complex for others. The primary tax potentially applicable is Capital Gains Tax (CGT), which applies to profits made when selling assets-including property. However, thanks to Private Residence Relief (PRR), most people selling their only or main home will be completely exempt from this tax.
For those who own multiple properties, have let their property, or have used it for business purposes, understanding the precise tax implications becomes crucial to avoid unexpected bills or penalties.
When Private Residence Relief Protects You From Taxation
Private Residence Relief automatically applies when you sell your home if all these conditions are met:
You’ve owned only one home and lived in it as your main residence for the entire period of ownership
You haven’t let part of it out (having lodgers doesn’t count as letting)
No part of your home has been used exclusively for business purposes
The grounds, including all buildings, are less than 5,000 square metres (approximately 1.2 acres)
You didn’t purchase the property solely to make financial gain
If all these apply, you’ll pay absolutely no Capital Gains Tax when selling. Even if some conditions aren’t met, you may qualify for partial relief, reducing any potential tax liability significantly.
How Capital Gains Tax Works on Property Sale?
If Private Residence Relief doesn’t fully cover your situation, you’ll need to understand how CGT applies to property sales. The tax is applied to the profit (or ‘gain’) made on the property-not the total sale price.
To calculate your gain:
Take the final selling price
Subtract the original purchase price
Subtract any eligible costs including buying costs, selling costs, and improvement costs
Subtract your CGT allowance (£3,000 for individuals in 2025-26)
Apply the appropriate tax rate to the remaining amount
The current Capital Gains Tax rates on property are shown in the table below. These rates changed on April 6, 2024, resulting in a reduction for higher-rate taxpayers.
| Taxpayer Status | CGT Rate on Property (from April 2024) | Previous Rate (before April 2024) |
|---|---|---|
| Basic rate | 18% | 18% |
| Higher rate | 24% | 28% |
Understanding these rates is important, but remember that your capital gain is added to your other income when determining which tax band applies. This means that a large property gain could push even a basic-rate taxpayer into the higher-rate band for some portion of their gain.
Do I Pay Tax When Selling a House I’ve Only Partially Lived In?
If you’ve only lived in your property for part of your ownership period, perhaps because you’ve rented it out or it was a second home, you’ll receive partial Private Residence Relief. The calculation is relatively straightforward:
(Months you lived in property + final 9 months) ÷ Total months of ownership = Percentage of gain exempt from CGT
For example, if Mark from Exeter owned his house for 10 years (120 months) but only lived in it for 6 years (72 months), the exempt portion would be:
(72 months + 9 months) ÷ 120 months = 67.5%
This means 67.5% of his gain would be exempt from CGT, with the remaining 32.5% subject to tax after deducting his annual allowance. When Mark found himself struggling with this calculation and worried about potential penalties, he contacted Property Saviour and we suggested contacting a tax specialist for advice. Our team walked him through the process and offered a guaranteed quick sale option that eliminated his tax worries and provided the certainty he needed during a stressful time.
How Long Do I Have to Report and Pay Property Sale Tax?
Since April 2020, HMRC has tightened the reporting timeframe for property sales. If you have Capital Gains Tax to pay on a UK property sale:
You must report and pay any due tax within 60 days of completing the property sale.
This is a significantly shorter window than the previous system, which allowed reporting on your annual Self Assessment tax return. Failure to report and pay within this timeframe can result in penalties and interest charges.
For those concerned about meeting these deadlines or uncertain about their tax liability, working with a professional or considering a straightforward sale to a cash house buyer can simplify the process considerably.
Is It Possible to Reduce Capital Gains Tax When Selling Property?
There are several legitimate ways to reduce your potential CGT liability when selling property:
Keep detailed records of all improvement costs to increase your property’s base cost
Use your annual CGT allowance strategically (currently £3,000 per person)
Transfer ownership percentages between spouses to utilize both allowances
Consider selling toward the end of the tax year if you’ve already used your allowance
Time your sale to maximize periods of deemed occupation under PRR rules
One insight we’ve gained from our Reddit community discussions is that many sellers overlook the significance of the “last 9 months rule.” This provision automatically treats the final nine months of ownership as a period of occupation, regardless of whether you actually lived in the property during that time. At Property Saviour, we’ve seen numerous cases where this rule has substantially reduced clients’ tax liabilities, sometimes saving thousands in unexpected tax bills.
Do I Need to Pay Stamp Duty If I Inherit a House With a Mortgage?
Inheriting a property with an outstanding mortgage doesn’t trigger Stamp Duty Land Tax liability on the inheritance itself. However, if you take on the mortgage as part of accepting the inheritance, HMRC may consider this as “consideration” for the property, potentially creating a stamp duty liability on the mortgage amount if it exceeds the current threshold.
This is a common misunderstanding we encounter at Property Saviour. Many beneficiaries assume they’re exempt from all property taxes when inheriting, only to be surprised by potential SDLT implications. If you’re dealing with an inherited property and feeling overwhelmed by the tax complexities, our team can provide straightforward advice or even offer a quick, guaranteed purchase if you prefer to avoid these complications entirely.
What Happens If I’ve Rented Out My Property Before Selling?
If you’ve rented out a property that was previously your main residence, the tax situation becomes more complex. Before April 2020, lettings relief provided substantial tax benefits in this scenario, but this has now been restricted to only apply when you shared occupancy with your tenants.
For properties that have been rented out:
The period you lived in the property qualifies for Private Residence Relief
The final 9 months of ownership automatically qualify for relief
Any period of absence up to 3 years may qualify for relief under specific circumstances
The remaining period will be subject to Capital Gains Tax
We recently worked with Janice from Reading who had rented out her property for 4 years of her 10-year ownership. She was concerned about a potentially large tax bill when selling. After calculating her partial Private Residence Relief and accounting for eligible renovation costs, her accountant was able to demonstrate that her actual tax liability was much lower than feared. For those facing similar situations and seeking certainty, Property Saviour offers a straightforward property buying service that removes the stress of complex tax calculations and market uncertainties.
Do I Have to Pay Capital Gains Tax If I’m Auctioning a House?
When selling a property through auction, the Capital Gains Tax rules remain exactly the same as with a traditional sale. The method of sale doesn’t affect your tax liability-what matters is your relationship to the property (whether it was your main residence) and how you used it during your period of ownership.
Auctioning a house might be faster than a traditional sale, but it doesn’t change your tax obligations. You’ll still need to report and pay any CGT within 60 days of the auction completion if the property doesn’t fully qualify for Private Residence Relief.
What Happens If I Don’t Declare Property Sale Tax?
Failing to declare property sale tax when required is considered tax evasion and carries serious consequences. When you sell a property, you must declare on the documentation whether it was your primary residence. Providing false information to avoid tax is fraud.
HMRC has significantly improved its property transaction tracking systems in recent years. Land Registry updates are automatically cross-referenced with tax records, and solicitors are increasingly vigilant about encouraging proper CGT declarations.
An insight from property forums suggests that HMRC often sends reminder letters roughly 10 months after property sales if they haven’t received expected CGT submissions. The investigation window for property transactions can extend up to 20 years, with penalties potentially including:
Up to 100% of the tax due for deliberate non-disclosure
Interest charges (currently around 7.75% per annum)
Potential criminal prosecution in serious cases
At Property Saviour, we understand that facing property tax can be overwhelming, especially during already stressful moving periods. If you’re concerned about potential tax implications from your property sale, our team suggest speaking to a tax specialist help clarify your situation or offer an alternative hassle-free sale option as a professional we buy any house service provider.
