Capital Gains tax on previous home i lived in then let out

Hi, Me and my wife are thinking of selling a home we own, which we brought on 31st October 2008. We lived in this house as our main residential home until we brought another house which we moved into on 1st December 2015. We have now rented this house out to a private tenant from the 1st December 2015 until now. If we do sell this house, can we claim Private Residence Relief for the time we lived in this house as our main residence and take this off the capital gains tax? (from 31/10/08 till 01/12/15) If so do we add an extra 9 months relief to the end of ownership term? We both do our own tax self assessments online each year. Would we just just split the capital gains house sale on our self assessment 50/50 as well? Thanks Richard

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.
