Hi rstubbs10,
As this property was you main residence, you can claim Private Residence Relief for the number of months that the property was your main residence.
Please also add a further 9 months to this figure.
You should then work out the number of months that you owned the property.
This will give you the fraction number of months main residence over the number of months owned.
Please have a look at the guidance here:
HS283 Private Residence Relief (2024) As you are married, the default split on jointly owned property is 50/50.
There is a calculator here:
Tax when you sell property
To help you both work out your capital gains.
You can also create a capital gain account each and report and pay your Capital Gains Tax liability.
Please note that you have 60 days from the completion date to report and pay your Capital Gains Tax.
Thank you.
