CGT on only property

Hello, I own a home which I originally lived in but have since let out after moving into my partner's home (which is entirely in their name but I do contribute to the bills). If I were to sell the house I own but go onto the deeds/mortgage with my partner am I still liable for CGT? Alternatively if I sell the property but do not effectively buy in with my partner am I still liable for CGT with it being the only property that I own? Thanks

Hi Louise Brockbank,
Yes, only if you are married or civil partners, can you transfer assets between spouses or civil partners and there be no capital gains liability.
The share that you would give to your partner, would be subject to Capital Gains Tax liability.
As the property was your main residence for a period of time, you will be entitled to some Private Residence Relief, which would reduce the amount of gain tax would be payable on.
Have a look at helpsheet HS283 at:
HS283 Private Residence Relief (2023)
for more information.
There is guidance and a calculator at:
Tax when you sell property Skip to contents of guide Contents
To help you work out your gain.
Capital Gains Tax on residential property and land needs to be reported and paid within 60 days of the completion date.
At the end of the calculator, you can register for an online capital gains account, which you can use to report and pay the tax due.
Penalties and interest apply to late filing and late payments of tax.
Thank you.
