Setting the story straight on ATO systems::

ATO systems are back up and running with full functionality, following a disruption this afternoon.

The issue experienced today does not relate to the ATO’s capability and capacity to deliver for Tax Time 2017. It is not related to recent hardware issues or our storage area network (SAN). No data has been lost and our systems were not compromised or subject to a cyber-attack.

We identified intermittent system issues early this afternoon affecting our mainframe and impacting on our services to the community. This was caused by applications running incorrectly. We took controlled action to reboot our mainframe and resolve this issue.

We then brought our services back online methodically to ensure system availability and stability.

While an outage is not optimal, our decision today to address our degraded system performance was to ensure they were fully operational for the 8.00-9.00pm window when we know the majority of people choose to lodge their tax returns.

The ATO operates a highly sophisticated and complex IT environment. We do whatever we can to minimise any impact on our ability to provide reliable services to the community, our key stakeholders – practitioners, the superannuation industry and digital service providers – and the Government.

Today’s issues impacted ATO Online services (including myTax), The Tax Agent, Business and BAS Agent Portals, Standard Business Reporting (SBR), Australian Business Register (ABR) and our case management systems. The ATO website remained online during this period.
