Private Residence Relief Explained: A Clear Guide to Minimising Capital Gains Tax on Your Home Sale

When you sell your home, you might have to pay Capital Gains Tax (CGT) on any profit made. However, Private Residence Relief (PRR) can reduce or even eliminate this tax if the property was your main home during the time you owned it. This relief is designed to protect you from paying CGT on the gain from selling your main residence, making it an important factor to understand when selling your property.

Your eligibility depends on how long you lived in the home, whether you had more than one property, and any periods when the house was not your main residence. There are specific rules that can affect how much relief you get, like the 9-month exemption after you move out. Knowing these details can help you plan and possibly save a significant amount on your tax bill.

If you want to avoid unexpected costs when selling your home, it’s important to learn how PRR works and what you need to do to claim it correctly. Understanding the basics of this relief can give you confidence and control over your finances during the sale. For more detailed guidance on how Private Residence Relief applies, see this guide on tax relief when you sell your home.

Understanding Private Residence Relief

Private Residence Relief (PRR) helps reduce or eliminate the Capital Gains Tax (CGT) you may owe when selling your main home. It applies when certain conditions about your residence and ownership are met. Knowing who qualifies and what counts as your main residence is essential to claim this relief correctly.

Definition and Purpose of Private Residence Relief

Private Residence Relief is a tax relief aimed at homeowners selling their main residence. It reduces or removes the Capital Gains Tax charge on the profit you make from selling your home. The relief mainly protects you from paying tax on gains if the property was your principal home during the ownership period.

PRR covers the time you lived in the home and a final 9-month period after you move out. This relief also includes specific rules if you had periods when the home was rented out or used for non-residential purposes. Understanding how PRR works helps ensure you don’t pay unnecessary tax when selling your property.

Who Qualifies for Private Residence Relief

You qualify for Private Residence Relief if the property has been your only or main residence during the time you owned it. You must have lived in the home as your principal place of residence. Homeowners who have lived abroad or had multiple properties may have to nominate which one is their main residence for tax purposes.

Certain periods, such as short absences or letting the property, may still count towards your relief, depending on the rules. If you owned more than one home, you must inform HMRC which property you want to treat as your main residence to claim PRR. Being clear about your residence status helps you avoid CGT on most or all of your gain.

Main Residence for Tax Purposes

Your main residence is the home you live in most of the time and regard as your principal home. It must be where you usually reside, not just a holiday house or investment property. For tax purposes, the main residence determines eligibility for PRR on any capital gain from selling that home.

If you own two homes at once, you can nominate which property is your main residence for up to 2 years after owning both. If you don’t make a nomination, HMRC decides based on the facts. To qualify, the property must be your only or main residence during ownership, with some allowance for short gaps or periods of absence.

How Capital Gains Tax Applies to Home Sales

When you sell a property that isn’t fully covered by reliefs, you might need to pay Capital Gains Tax (CGT) on any profit. Understanding how the total gain is calculated, which sales are subject to CGT, and how your ownership period affects this will help you manage the tax due.

Calculation of Total Gain

Your total gain is the difference between your property’s selling price and the purchase price, minus any allowable costs. These costs can include:

• Purchase and sale fees (such as solicitor and estate agent fees)
• Improvements that add value (not general maintenance)
• Costs of buying or selling the property

You subtract these costs from your sale price to find the gain. If you sold the property for less than you paid, there is no gain and no CGT to pay.

Tax-free allowances may reduce the amount of gain subject to CGT, but the total gain must first be worked out clearly.

Property Sales Subject to Capital Gains Tax

Not all property sales trigger CGT. Your main home is usually exempt from CGT because of Private Residence Relief. However, CGT may apply if:

• You sell a second home or investment property
• You have let out part of your home (letting relief might apply)
• The property was not your main residence for the entire ownership period

If you own more than one property, you might need to nominate which is your main home for CGT purposes.

Total Period of Ownership

The total period you own the property affects how much relief you get. You won’t always pay CGT on the entire gain.

Private Residence Relief exempts you from CGT for the periods when the property was your main home. This includes:

• The time you lived in the property
• The last 9 months of ownership, even if you weren’t living there

If you rented out or used part of the home for business, those periods may not get relief and can increase your CGT bill. Keep records showing your occupation and use of the property to support your claim.

For detailed guidance on CGT and reliefs, visit the GOV.UK page on tax when you sell your home.

Qualifying Conditions and Exemptions

You need to meet specific rules about your ownership, use, and the property’s details to claim Private Residence Relief. The property must primarily be your main home, and only certain parts of the land around it are covered.

Qualifying Conditions for Private Residence Relief

To qualify, you must have owned and lived in the property as your main home during the period you’re claiming relief for. The relief usually covers the entire time you used it as your main residence, plus up to the last 9 months before sale, even if you weren’t living there then.

If you had more than one home, you can only nominate one for relief if owned at the same time. You must inform HMRC within two years of buying the second home. Certain gaps in residency can still allow partial relief if the home was genuinely your main address.

Grounds and Permitted Area

The relief applies to the land used “mainly for your private residential use”. HMRC sets a limit called the “permitted area,” usually meaning the land you use as part of your home and garden.

Land that is essential for the property’s enjoyment, like a driveway or yard, usually qualifies. But larger plots with business use or rented parts might not be included in the relief. You should identify which part of your property is allowed under these conditions.

Gardens and Outbuildings

Gardens and grounds up to 5,000 square metres (about an acre and a quarter) usually qualify if they are used as part of your home. This includes sheds, garages, or other outbuildings linked to your main residence.

If the gardens are significantly larger or partly used for business, the relief might not cover that extra land. Detached buildings not used for residential purposes or rented out can also be excluded. Always check the usage and size to know which parts are tax exempt under Private Residence Relief.

For more detail on rules and exceptions, see Private Residence Relief – GOV.UK.

Special Scenarios Affecting Relief

Certain situations can change how much Private Residence Relief (PRR) you get. These include times when you are not living in your home, changes in your family situation, and owning more than one property.

Periods of Absence and Residential Care

You can still claim PRR if you are away from your home for specific reasons. For example, if you move into residential care, your home may qualify for relief for up to 36 months of absence.

If you rent out your home during an absence, you might still get relief under certain conditions, but “letting relief” only applies if you lived there as your main home before renting. The last 9 months of ownership always count as a period when you lived in the property, even if you weren’t there.

Keep a clear record of these times, as HMRC checks periods of absence closely to decide your relief.

Divorce and Separation

After divorce or separation, you may jointly own a home or sell it at different times. You can still claim PRR on a property you once lived in as your main home, even if you don’t live there at the time of sale.

If you and your ex-spouse own multiple homes, you can choose which one is your main residence for relief purposes. The choice must be made within two years of owning both properties.

Be aware that if you transfer ownership of the property as part of a divorce settlement, relief depends on how long you lived there before and after the split.

Multiple Homes and Changing Main Residence

If you own more than one home, you must decide which is your main residence to get full PRR on that property. You have up to two years to nominate which home is your main one.

If you change your main residence, you can still claim relief for the first home for up to 36 months after you move out. This helps if you recently bought a new home.

HMRC looks at where you spend most time, work location, and family ties to confirm your main home. If you don’t nominate, the relief is given automatically to the property that appears to be your main home.

Lettings Relief and Business Use of the Home

When part of your home is rented out or used for business, your tax relief options change. The amount of relief you can claim depends on how the property is occupied and for how long. Knowing what counts as letting or business use is key to reducing your Capital Gains Tax.

Letting Relief for Lodgers and Tenants

Letting relief can reduce the Capital Gains Tax (CGT) bill when you rent out part of your main home. However, since 2020, this relief applies only if you actually lived in the property while renting it out.

The relief covers the lower of three amounts:

• The gain attributable to the part rented out
• £40,000
• The amount of Private Residence Relief (PRR) you are entitled to

If you rent to lodgers (people sharing your home), you can usually claim full relief on the gain linked to that part. If you have tenants living separately in part of your home, relief applies only if you lived there too.

Letting relief does not apply if your home was purely a rental property while you lived elsewhere. For more details on how this works, see lettings relief in the UK.

Business Purposes and Impact on Relief

Using part of your home for business can affect your Private Residence Relief. If you run a business from your home, you may lose relief on the business area unless you can prove it is small and incidental to personal use.

Business use can include having a home office or workshop. If you sell the property, you need to calculate your gain separately for the business and personal parts. The business part might be liable for CGT without relief.

Keeping good records of time and space used for business helps to claim the correct amount of relief. You may need to get professional advice to understand how your business activities affect your tax position. For more on this, see tax when you sell your home.

Special Considerations for Married Couples, Civil Partners, and Non-UK Residents

When dealing with Private Residence Relief, the rules for married couples, civil partners, and non-UK residents differ in important ways. Your tax position can change based on your relationship status, residence status, and whether the property is in the UK or overseas.

Rules for Married Couples and Civil Partners

If you are married or in a civil partnership, you can transfer property ownership between you without causing a Capital Gains Tax event. This means you can effectively combine periods of ownership to maximise your Private Residence Relief. You are allowed to nominate which home is your main residence if you each own properties. This affects which property qualifies for relief.

Special relief rules also apply when couples separate or divorce, allowing more flexibility in claiming relief when the home is sold. However, for tax purposes, you and your partner are treated as individuals, so you each need to claim relief separately on your share of the gain.

For detailed guidance on transfers and nominations, see Private Residence Relief for married couples and civil partners.

Implications for Non-UK Residents and Overseas Property

If you are not UK resident, Private Residence Relief rules still apply, but the conditions are stricter. Non-UK residents can only claim relief for the time the property was your main home and during the last 9 months before sale.

For overseas properties, Private Residence Relief generally does not apply unless the property is within the UK. Gains on overseas property may be subject to Capital Gains Tax depending on your UK residency status and any applicable tax treaties.

Non-UK residents selling a UK home must report the sale and may have tax to pay if relief does not cover the full gain. It is essential to check up-to-date rules for non-residents on tax when you sell your home.
