I have been asked for a VAT registration number for my Medico-Legal work. Why do I need to supply that?
Medico-Legal work is not exempt from VAT, but you do not have to register unless your Medico-Legal income exceeds the VAT threshold. You should check with your Accountant, as this threshold and the rules are subject to change. If you are VAT registered, then you must display your VAT registration number on your invoice.
