The ATO is developing new online services systems as AUSKey will be retired in March 2020
Replacing AUSKey will be myGovID and Relationship Authorisation Manager (RAM).
MyGovID is an authentication service that will allow individuals to prove who they are online. This system will work by establishing your identity once online and then using your myGovID credentials to access government services you need online.
Relationship Authorisation Manager (RAM) is an authorisation service that allows you to link your myGovID to an ABN, managing authorisations across government services, for businesses and their staff. RAM gives you the ability to add multiple businesses, access the business portal on behalf of multiple businesses, modify authorisations, customise and delegate the level of business authorisation for employees and nominate who can act on behalf of your practice.
MyGovID and RAM are currently available in a public beta for eligible businesses to access the ATO Business Portal and will soon be available for online services for agents. AUSkey can still be used to access online ATO services while myGovID and RAM are being developed.
The ATO advises that in preparation for the changes you check your ABN details are up-to-date in the Australian Business Register (ABR).
