When selling your property in the UK, the possibility of paying Capital Gains Tax (CGT) can be a significant concern. However, there is a way to reduce or eliminate your CGT liability through Private Residence Relief (PRR). If you meet the criteria, PRR can offer a valuable tax exemption, saving you from paying CGT on the profits from the sale of your property. This guide covers everything you need to know about PRR, how to calculate it, and how it interacts with other reliefs like Letting Relief.

Private Residence Relief is a tax relief that can reduce or eliminate the CGT liability when selling a property that has been your only or main residence. The aim of PRR is to allow individuals to sell their homes without having to pay tax on any gain, as long as the property was used primarily as a home during ownership.
PRR can be applied to both individuals and trustees, but not to companies. Importantly, it applies to the gain made on the sale of the property, not the entire sale price. This means that if the property has increased in value since you purchased it, you can potentially avoid CGT on that increase if PRR applies.
House owner has rights to deduct costs of buying, selling or making improvements in their property from the profits they received after selling it, which includes:
If you sell a lease or you home is forcibly purchased then there are special rules for calculating your profits.
Whether you have to pay or report Capital Gain Tax (CGT) or not, you can find out only if you know your gain and how much tax relief you are entitled to. You can use the CGT calculator to work out how much tax you are liable to pay on your home. You can not use CGT calculator if:
To qualify for full Private Residence Relief, the following conditions must be met:

In some situations, you may not meet all the requirements for full PRR, but you could still qualify for partial PRR. This typically happens when you have used the property for part of your ownership for non-residential purposes or have not lived in it throughout the entire ownership period.
To calculate Partial Private Residence Relief, the gain from the sale is multiplied by the proportion of time the property was your main residence. For example, if you owned the property for 10 years and lived in it for 7 years, you would receive relief for 70% of the gain.

Whether you have one or multiple homes or lived in it or not, you are always entitled for last 18 months relief before you sold your house.
It should have been your only or main place of stay or residence at some point of time in your life while you owned it.
You are entitled for first 12 months relief from the home you owned, if both the following apply:
You will be entitled for relief for these periods, even if you have mentioned a different home as you main home or place of stay.
Following reasons make you entitled for relief if you were away from your own home:
It is necessary that you have lived in your home before and afterwards, unless you were prevented by your work.
If you have just one house you are entitled for last 36 months relief before you sold your home if one of the following apply:
Mostly, you are entitled for relief on for one home for any given period. It is suggested that you maintain records of your each property you lived in as your main home. In case of married couples or civil partnership, only one home per couple as main home for any period is entitled for relief.
If you have mentioned a property as your home, you won’t get relief from another property while your home is nominated, besides for the duration that all the time qualified for relief.
There are several other rules that can implicate your tax relief when you sell your home. Contact Capital Gain Tax helpline if you have any doubts about the rules and their purpose.
If you’re selling a property that has been your main home, the last 9 months of ownership are automatically covered by Private Residence Relief, even if you weren’t living there during that time. This is useful if you’ve moved out of the property but haven’t sold it right away.
For more about this topic, refer to our Main Residence Relief post.

If you own more than one property, it’s important to determine which one is your main residence for tax purposes. The concept of Private Residence Relief (PRR) is linked to the property that you designate as your main home. PRR allows you to potentially avoid paying Capital Gains Tax (CGT) when you sell your property, provided it was your main home for part of the time you owned it.
If you own multiple homes, you can nominate one property as your main residence for tax purposes. This must be done within 2 years of changing your main residence. Once nominated, the property will be eligible for Private Residence Relief for the time it was your main home.
For example, if you own two properties, one in London and one in the countryside, and you lived in the London home for 5 years and then moved to the countryside home, you can nominate the countryside property as your main home. However, this nomination must be made within 2 years of changing your primary residence.
From 6 April 2015, only if you have lived in a property or home for at least 90 days in the tax year, you can nominate a home/property abroad.
If you’ve rented out your home while it was your main residence, you may still qualify for Letting Relief. Letting Relief is an additional relief that can further reduce the CGT liability on the sale of a property.
Letting Relief can apply when part or all of your home was rented out. The maximum amount of Letting Relief is £40,000 (£80,000 for married couples or civil partners), but it’s important to note that this relief only applies to the part of your home that was rented out and was previously your main residence.
If you’re considering renting out your property, it’s crucial to understand the tax implications. Check out our blog on Buy-to-Let Tax Changes and Relief Calculator for more detailed information on tax reliefs for landlords.

You will be qualified for the lowest of the below mentioned:
Relief from letting your property/home does not include any amount of the taxable gain you earn while your home is vacant.
Capital Gains Tax may be affected by other rules that may make you liable to pay. Contact Capital Gains Tax helpline, if you have any doubts about the CGT and its paying methods.
When you let out part of your home/property, you will need to evaluate the proportion you lived in. Then you will be qualified only for private residence relief (PRR) on the part of your gain.
You may be qualified for Lettings Relief too.
The property or home where you have lived in as your only or main residence at some point of time and which has been let out as residential accommodation can qualify you for Letting Relief, which becomes a valuable relief for its reduced Capital Gains Tax (CGT) that is to be paid on the sale of the home/property.
To avail maximum relief from the property/home, living in it as an only and main residence for a short period can benefit as it also creates likelihood of claiming letting relief as well as it ensures exemption of the final 18 months of ownership from Capital Gains Taxes.
Lettings relief is obtainable when the taxpayer used a part of the property as the only or main residence and part of the same property is let out for use as a residence. The profit from the gain is shared out by mentioning the share of the property used for individual purpose. You can always contact a Capital Gains Tax helpline to understand the calculations in a better way.
You are entitled for lettings relief when all or part of your home/property is let out for residential purposes while another part of the property is used as only and main residence of the taxpayer during a certain period of the ownership. As a result, to make the home or property as the only and main residence for living for the taxpayer for some point of time to bring the gain within the purview of letting relief can be beneficial from a CGT’s point of view.
The calculation for Private Residence Relief is straightforward when you meet the eligibility conditions:

Step 1: Calculate the gain you made from the sale of the property (selling price minus purchase price and any allowable costs such as renovation or improvement costs).
Step 2: Determine the period of ownership and the period you lived in the property as your main residence.
Step 3: Apply the formula:
| Private Residence Relief = | (Period of Ownership) | x Gain on Sale |
| (Period of Occupation) |
For example, if you owned the property for 10 years, lived in it for 7 years, and made a gain of £100,000 on the sale, your PRR would be 70% of that gain (£70,000). The remaining 30% (£30,000) would be subject to CGT.
Private Residence Relief is a valuable tax exemption for homeowners in the UK. By understanding the conditions and rules, you can ensure that you don’t pay unnecessary Capital Gains Tax on the sale of your home. If you have more than one property or have let part of your home out, the additional reliefs like Letting Relief can further reduce your tax liability.
To make sure you qualify and maximise your relief, it’s always a good idea to consult with an accountant who can guide you through the process and ensure you meet all requirements.

If you make a loss on the sale of your property, PRR won’t apply to reduce your losses. However, the loss could potentially be offset against other capital gains you make in the same tax year.
Yes, if you are a non-resident but have lived in the property as your main home at some point, you can still claim PRR. However, the rules may differ, and you should consult an accountant to ensure you are eligible.

Yes, in certain situations, you can claim both PRR and Letting Relief if part of your property was rented out during the period it was your main home. This can significantly reduce your tax liability.
