The Tax Office is on track to slash nearly one third middle-management in just over two years, the latest figures show.
And up to 12 per cent per cent of surviving middle managers at the Australian Taxation Office want to quit their jobs with more than 550 of them applying for voluntary redundancies.
But about 100 of the executive level I and 2 public servants look set for the disappointment of keeping their jobs with the latest round of redundancies only scheduled to include 450 employees.
The oversubscription to the redundancy offer is not the first rush to the exits the Office has seen in recent times with 2187 workers applying for just 500 payouts in February 2014.
The latest figures indicate that the ATO is making real progress in its stated aim to deliver a flatter structure and improve its manager to rank-and-file ratio.
In June 2013, the office had 6154 EL1s and EL2s but on Tuesday, a spokesman confirmed that number had shrunk to 4805.
The new round of redundancies will bring the reduction to about 1800, or just under 30 per cent on the 2013 numbers.
Senior ATO figures told a stakeholder briefing last month that recruitment would focus on graduates and other entry level hiring for the foreseeable future.

Critics have complained about a loss of expertise among the experienced EL cohorts amid a storm of criticism in the past 12 months of the ATO's ability to raise revenue, particularly from large corporate taxpayers.
But an ATO spokeswoman insisted the Tax Office was still capable of doing its job.
"Our workforce rebalancing efforts at the executive levels are designed to remove unnecessary layers of management and broaden spans of control to ensure we have the right mix of capabilities and organisational structures in place going forward," she said.
"We are confident our remaining workforce is flexible, skilled and responsive and that our priority areas are properly resourced."
Across the service, it has been a tough few years for executive level public servants, even before the Coalition came to power and there is no end in sight.
Public servants in executive level 1 or higher roles were almost three times as likely to be retrenched as more junior officers in the final years of Labor in power.
Nearly 2600 ELs in the Department of Immigration and Border Protection are currently facing "individual capability assessments" including confidential interviews and behavioural testing.The move is partly in response to a previous audit report which said the two departments which had merged to form DIBP had too many middle managers with almost one in five EL2s in Immigration and almost one in six EL2s in Customs overseeing no staff.
The Defence Department has also embarked on a cull of layers of middle management. The Health Department has also expressed a determination to reduce its ratio of ELs to APS-level public servants.
Public servants in executive level 1 or higher roles are almost three times as likely to be retrenched as more junior officers, an analysis of staff departures shows.
