There is something in the latest VAT circular about the VAT treatment of Distance Learning Courses (although reading it again, having fished it out of the bin, I can't see anything that is 'informative' within it). All their publications are on
www.hmce.gov.uk
You can reclaim membership fees againt your tax code, but these will be low compared to the cost of the training (and may not be approved anyway).
I guess Mr B is assuming everybody is getting career development loans and paying with this, so paying tax once only as VAT ???
