No, but you must have a basic knowledge of the principles of taxation. If you don’t have this you can take the online, on demand, Level 2 Foundation qualifications in VAT, Personal and Business Taxation offered by the ATT. If you are interested in technology, but have no tax knowledge, we strongly recommend you take at least two of these courses before starting the Diploma.
