Principal Private Residence (PPR) Relief
A Principal Private Residence (PPR) is a house or apartment which you own and occupy as your only, or main, residence.
You will be exempt from
CGT if you dispose of a property that, for the entire period of ownership, you:
- lived in it as your main residence
- used all the property as your home.
This exemption also applies to land, up to one acre (0.405 hectares), around a house. This excludes the site of the house, which is not taken into account when applying the relief.
PPR Relief is restricted if you did not fully occupy the property or the sale price has development value.
Note
The last 12 months of ownership of a PPR is considered to be included in your period of occupation.
This allows for the possibility that you have moved into your new home, but have not sold your previous home.
Restriction if only part of your property was used as a home
You can only claim for the part of the house you used as your home. For example, you might have used half your house as your home, and half for your business. You can claim exemption on half of the chargeable gain.
Rent a Room Relief will not affect your claim for full exemption.
