Currently you cam only use an email address for one my gov registration. While the rationale is understandable. It doea not work effectively. This practice stops children from assisting parents or relatives to lodge tax returns. This is an easy fix which provides greater flexibility and will increase participation with My Gov
Thanks for your post and comments.
The Board is keen to hear of further examples to identify if there is a shared concern and general support to prioritise this idea.
The Board notes there is also a Whole of Government project working towards an authorisation solution that will enable individuals to manage authorisations and nominate a third party to act on behalf of a user. There are multiple phases of this project currently being scoped. The functionality required to enable individuals to authorise others is expected to be a later phase of the project and does not yet have a scheduled timeline for delivery.
