Hi Rose12,
We cannot advise on personal circumstances.
We can provide links to the guidance in this area.
Please have a look at helpsheet HS283:
HS283 Private Residence Relief (2024)
And Helpsheet HS281
HS281 Capital Gains Tax civil partners and spouses (2024)
For guidance on Capital Gains Tax.
There is a Capital Gains Tax calculator here:
Tax when you sell property
Which leads on to registering for a capital gains account, which you use to report and pay any Capital Gains Tax.
For more detailed advice, you would need to contact our Self Assesment helpline.
Self Assessment: general enquiries
Or seek professional advice.
Thank you.
