Capital gain on final sale of inherited property when half of the property was purchased from a

My sister and I have inherited our late mother’s house. My sister has agreed to sell her half to me and my wife. When my wife and I subsequently sell the house, which we anticipate will be within two years, would any capital gains be calculated on the half that we purchased from my sister, combined with any increase in value of the half I inherited? I am concerned that if the sale price of my sister’s half is solely used and compared with the final sale value, then a significant CGT liability will result.

Hi,
We cannot comment on future events as legislation may change. However, based on current guidance, CGT will be due if the property is not your main residence and that will be on both your half and the part purchased from your sister.
Thank you.
