I would like to make generous donations to charities whilst I'm still living. Not interested in the charity getting tax back or me having my own current tax situation adjusted. If I donate/give like this what administrative actions are required? Obviously I should record the info ready for my executor to eventually complete IHT forms but in the meantime should I ask charity to acknowledge receipt or will evidence of payment through my bank statement be sufficient? When I was completing my SA return there was quite a lot of 'help guff' on the subject that didn't make much sense to me so I can't determine whether these pre-death donations would need to be submitted on my SA return. Please help
