Help! Advice please. I sold a property that I owned with 2 other people with no bills in my name and I didn't change my impots form to the address that I was living in either! I have now received a huge plus value bill and would like any advice on how NOT to pay it. This property was genuinely my main place of residence but the tax office seems to only go by the address on tax return. Can anyone help please?
