ISA talk.17 Jan 2021 17:18
These are all nice problems to have but seem to be getting very complicated!
My understanding is that if your SAR shares are sitting in your ISA, then ANY gain is completely free of ALL taxes. Eg, you put your £20000 allowance in the form of your holding of SAR shares when they were, say 1p each. So you had 2 million shares. Your shares become valued at 20p due to market forces so your shares are now worth 2 million x 20p = £400,000, a gain of £380,000. You decide to cash in and close your ISA. Job done. The £400,000 is all yours!
