There should be a prompt / warning for a non-resident filing in the CGT pages with share disposal when in fact it is exempt and does not need to be completed (only residential property or shares in a property rich company are reportable). Personal tax happily let me enter the CGT share disposal of a trading company and gave me the CGT liability without warning. It ignored the non-residency. I was expecting the system to recognise non-residency like it does for income tax (dividends and excluded income)
