CGT on a joint property which was transferred to me

Hi, I owned a btl flat 50/50 bought for £120000 with my ex husband in 2016. He transferred his 50% to me after divorce and it was valued at £140000 at transfer. He paid CGT for this disposal at the time. If I wish to sell, do I calculate CGT based on 100% of the gain from £140000, and from 50% of the gain from £120000 to £140000? Thanks.

Hi,
You acquire the propety in 2 stages, so to work out your acquisition cost you take 50% of the value when purchased and add this to 50% of the value of when you acquire the second 50%. This is your acquisition cost and is deducted from the disposal value. To help you work out your gain, there is a calculator below, which includes a link to register for a capital gains account and report and pay any gain within 60 days of the completion date.
Tax when you sell property
Thank you.
