“Since approximately 9:30 am AEDT on Monday 12 December 2016, the entire Australian Taxation Office website — including the tax agent and BAS agent portals — shut down due to a ‘world first’ hardware issue.”
Since approximately 9.30am AEDT Monday, 12th December 2016, the entire Australian Taxation Office (ATO) website including the tax agent portal has shutdown due to a “world first” hardware issue. Many internal processing systems for ATO staff were also affected by these hardware issues leading to many ATO internal systems being taken offline.
The media statement released today from the acting Chief Information Officer Steve Hamilton explains that; ‘these outages relate to a new hardware storage solution that was upgraded in November 2015. Our primary back-up systems, that should have kicked in immediately, were also affected. We understand this is the first time this problem has been encountered anywhere in the world and we are working with Hewlett Packard Enterprise (HPE) to determine the underlying cause. While these investigations are ongoing, we have had to implement alternative recovery procedures that are taking longer to complete.’
The ATO have not announced a definite time frame on when the general public including tax practitioners can expect the ATO online services to resume operating.
Please note that during this time whilst the ATO are working to resolve their hardware and system issues, we are unable to access our clients accounts with the ATO through the tax agent portal, nor are we able to liaise on client specific matters with the ATO through the tax agent phone services hotline.

“Although the website and agent portals were restored, many systems were still not fully functional while the ATO worked around the clock to rectify the underlying problems.”

The failure affected the public website and key portals used by tax and BAS agents, creating widespread disruption for taxpayers and practitioners.
Because the backup system did not function as intended, the ATO had to implement alternative recovery procedures.
Although core portals were brought back online, parts of the ATO’s processing ecosystem remained affected for some time while fixes were completed.

The ATO’s website, tax agent portal and BAS agent portal were taken offline unexpectedly because of a serious hardware failure, causing major disruption to online access and internal systems for staff.
The outage began at around 9:30 am AEDT on Monday 12 December 2016, when a new hardware storage solution unexpectedly failed.
Not only was the public website unavailable, but internal processing systems used by ATO staff were also impacted, meaning many online services and phone support channels were disrupted.
The ATO brought the website and agent portals back online by 14 December 2016, but some systems were still not fully functioning as the recovery continued.
The downtime was caused by a rare hardware failure that affected both primary systems and backup storage, meaning the usual fail-safe processes did not work as expected, and recovery took extra time.
No — the article notes that many internal ATO systems were also affected and taken offline due to the hardware issue.
Changed to this company in 2019 from former accountant and love their approach of organizing everything for me face to face with Xero set up plus being able to call as much as I need for set annual fee. They also picked up on something that was not done correctly by my former accountant and saved me $4k for this.
They the truly the best, Martin and Judy are so experienced, knowledgeable & professonal, also quite like speaking with Rose : ) all people are so lovely!
