The ATO is developing new online services to replace AUSKey as it hasn’t kept up with modern technology. MyGovID and Relationship Authorisation Manager (RAM) will be replacing AUSKey which is due to retire in March 2020.
The ATO advises that in preparation for the changes you should check your ABN details are up-to-date in the Australian Business Register (ABR).
MyGovID is an authentication service that allows you to prove who you are online.
Relationship Authorisation Manager (RAM) is an authorisation service that allows you to link your myGovID to an ABN and manage who can act on behalf of your business online.
MyGovID and RAM are currently available in a public beta for eligible businesses to access the ATO Business Portal.
AUSkey can still be used to access online ATO services while myGovID and RAM are being developed.
