CGT Rules When Selling Your Home

This section explains how to use 'Private Residence Relief' to avoid paying Capital Gains Tax when you sell your home in the United Kingdom.

In most cases, you do not need to pay CGT on any profits made after selling your main home (e.g. your primary residence).

How Does 'Private Residence Relief' Work?

The tax rules differ on a property that isn't your main home and if you sell your UK home as a non-resident (e.g. while living abroad).

You can use an online tool to work out tax relief when selling a primary residence (on GOV.UK). You can also find out:

Note: The rules on capital gains allow married couples (and people living in a civil partnership) to count only one (1) property as the primary residence (main home) at any one time.

In the United Kingdom, you do not have to pay Capital Gains Tax (CGT) when you sell your house (or dispose of) as long as you have (all):

You will be eligible for full Private Residence Relief (one of the tax reliefs in the United Kingdom) if all the above apply to your circumstances. If not, you may need to pay a partial tax.

How to Calculate the Gain?

The gain is defined as the positive difference between the purchase price of an asset and the amount received by selling it. Even so, you would need to use the current market value rule in circumstances where you:

Important: You would only pay tax on profits (realised gains) since the 5th of April 2015 if HMRC classifies you as non-UK resident for tax purposes.

Deducting Costs from the Gain

You will be able to deduct certain costs from Capital Gains Tax when you sell your house (e.g. when purchasing, selling, or making improvements). Some of the costs you can deduct from the gain include:

Some of the costs you cannot deduct from the gain include interest on a loan used to buy the property. You can contact HM Revenue and Customs for further information.

HMRC guidelines explain Capital Gains Tax liabilities when reporting a disposal of land, a compulsory purchase, if you are selling a lease, and for valuations of land (see Self Assessment helpsheet HS292).

Important: You would need to report and pay Capital Gains Tax within sixty (60) days after selling your home in the United Kingdom.

Living Away from the Home (absence)

You may still qualify for some Private Residence Relief even if you are living away from your home. But, the relief may only apply to certain periods of absence from home.

Periods that Always Get CGT Relief

The last nine (9) months before selling a home always qualifies for relief. This rule applies - no matter where you were living at the time and even if you own multiple properties.

To qualify, it would need to have been the main or only residence that you had at some point during the time you owned it.

Private Residence Relief also applies to the two (2) year period when you first owned the home (even if it wasn't nominated as your main home), as long as (both):

Having Only One home (or nominating it)

You get relief if you own only one home (or you nominated as your home) if you are away from it for any reason for periods adding up to three (3) years, or for:

Unless your work stopped you from doing so, you would need to have lived in the property before and after the period(s) to qualify for relief.

Owning only one (1) home means you would qualify for relief for the last thirty six (36) months before selling it, if you (any):

Note: Selling the home before the 6th of April 2020 would qualify for relief for the last eighteen (18) months if none of them apply to your circumstances.

Owning More than One Home

As a rule, residence relief only applies for one home (and per couple) for any given period. Thus, you may need to work out when you lived in it as the 'main' one for each property.

Also, other than for the periods that always qualify for relief, you cannot get it for another property for the time that you have nominated your home. You can contact the Capital Gains Tax helpline with general enquiries.

PRR Example:

Even though you have owned your home for twenty (20) years, you were living away for five (5) of them (i.e. 25%).

Because you didn't live away during the last nine (9) months or any other period that qualifies, the amount of gain that qualifies for Private Residence Relief (PRR) would be reduced by one quarter (25%).

Nominating a Property as Your Home

Writing to HM Revenue and Customs (HMRC) is the recommended way to nominate one property as your main dwelling. Remember to include the full postal address and have all the owners sign the letter.

You must tell HMRC within two (2) years if you want to nominate a different home (e.g. when the combination of homes changes).

Important: Since the 6th of April 2015, you would need to have lived in an overseas property for a minimum of ninety (90) days during the tax year to nominate it.

Letting Out Your Home to a Tenant

You may need to pay Capital Gains Tax when you sell your home if you have let it out to a tenant. But, HMRC will not consider you as letting out a property if (either):

Paying Tax on the 'Chargeable Gain'

The 'chargeable gain' refers to any realised profit less any qualifying Private Residence Reliefs. For CGT purposes, full relief relates to the:

The relief would apply for the last eighteen (18) months that you owned it, if you sold it between the 6th of April 2014 and the 6th of April 2020.

Letting Out Part of a Home

In this case, because Private Residence Relief (PRR) would only apply to a proportion of the gain, you would need to calculate the portion that you lived in.

How to Claim Letting Relief?

You may qualify for Letting Relief on gains made when selling your main home if you lived in it and had tenants at the same time. Letting Relief would be (the lowest):
