Hi all, I’ve just opened a Capital Gains Tax on UK property account on gov.uk website. I thought it might be easy or straightforward but already the first question has me confused. Am I filling the form in for myself ** ‘yourself’ ? (First option) Or **The estate of a person and the property was sold after they died You’re a personal representative? (Last option) So basically I’m an executor of my fathers will and also a beneficiary, I have just sold his house and need to pay CGT . Is there notes or glossary about filling in this online form that I can refer to ? Best wishes and thank you
