i bought a mare about 2 years ago from england for about 10k and it won 2 small races and it is very well related to a very good horse and i decided to sell it in a recent sale and it made 125k so if i take this money off my mortgage of 170k is that allowed or do i have to pay cgt or income tax or is it tax free its a tough question and will give a donation to askaboutmoney if i get a good true response
