I think I know the answer to this but DH wants me to check with the collective wisdom of Mumsnet before arguing with our accountant.
My father died 15 years ago, leaving his house equally to my sister and me, value £350,000, DH and I took out a £175,000 mortgage to buy my sister’s half.
We have rented the house out for 15 years and have now sold it for £520,000.
Our accountant’s initial calculation for CGT is based on us having paid £175,000 for the property, ie tax to be paid on £355,000.
I think that we should be paying CGT on the difference between the initial value of the property £350,000 (my inherited £175,000 plus the £175,000 we paid to my sister) and the selling price, ie £170,000.
Am I missing something?
