When submitting an application for a tax registration revenue expects a fully completed tax registration form. Applications for registration in any other format, e.g., letter, fax, etc. will not be accepted.

There are a number of different registration forms, each catering for a specific category of taxpayer.

You should ensure that you are using the correct form for the person who is registering.
