Old Portals close as at end of November.
As ICB previously advised the ATO would close the old portals sometime soon.
“Following recent consultation, a decision has been made to decommission the legacy Tax and BAS agent portals at 11:30pm (AEDT) on Friday 29 November 2019. This decision comes at the end of the transition period from the old tax and BAS agent portals to Online services for agents.”
Most BAS agents are already using the new Online Services.
You may continue to use your Auskey to login to the new online services. Note: auskey is 99% likely to be turned off in March 2020. So read the ICB guides and explanations and start moving to myGovID.
With the continual major system upgrades of the ATO especially with changes to systems over the Christmas period the old portals would be one more and more ineffective and out of date.
