Thinking About Part-Time Work or Returning to the APS? Don’t Let PSS Myths Cost You

For many Australian Public Service employees, the Public Sector Superannuation Scheme (PSS) is one of their most valuable financial assets.

Yet we regularly meet APS employees who delay retirement, reject flexible work arrangements or hesitate to return to government employment because of misunderstandings about how PSS actually works.

Two myths come up time and time again:

Myth #1: Going part-time will reduce my Final Average Salary and destroy my PSS benefit.

Myth #2: If I return to the APS later in my career, my old PSS benefit won’t benefit from my new salary.

Both assumptions can lead to poor career and retirement decisions.

The reality is often very different.

Myth #1: Going Part-Time Will Reduce My Final Average Salary

This is arguably the most common misconception we hear from PSS members.

Many APS employees assume that reducing their hours from five days per week to three or four days per week will significantly reduce their Final Average Salary (FAS) and therefore their future retirement benefit.

However, that’s not generally how PSS works.

PSS uses a member’s super salary when calculating the Final Average Salary. Importantly, PSS super salary is based on the full-time equivalent salary for the position, and working part-time does not reduce a member’s super salary.

To put it simply:

If an EL2 position is paid $180,000 per annum full-time, a member working 0.6 FTE may only receive $108,000 in actual salary, but their PSS super salary continues to be based on the full-time equivalent salary of $180,000.

This distinction is critical because many members incorrectly focus on their reduced take-home pay rather than the salary that is actually used within the PSS formula.

So What Does Part-Time Work Affect?

While part-time work generally does not reduce the salary used to calculate FAS, it does affect how quickly your PSS benefit grows.

Specifically, it impacts the Accrued Benefit Multiple (ABM).

The ABM is one of the key components used to calculate a PSS defined benefit. While working part-time, the ABM continues to increase, but the increase is pro-rated to reflect the reduced hours worked. In other words, the benefit continues to grow, but it grows more slowly than it would if you were working full-time.

In practice, this means:

• Your previously accrued benefit remains intact.
• Your super salary continues to be based on your full-time equivalent salary.
• Your future benefit accrual continues, but at a slower rate while working reduced hours.

This is a very different outcome from the one many APS employees fear.

We’ve worked with clients who delayed moving to part-time employment for years because they believed it would significantly damage their PSS benefit. After understanding how the scheme actually operates, many realised the impact was far less severe than they had assumed.

Why This Matters

The APS has embraced greater workplace flexibility over recent years.

Many employees would like to reduce their workload, spend more time with family, care for ageing parents, transition gradually toward retirement, or simply create a better work-life balance.

Yet concerns about PSS often become one of the biggest barriers.

Understanding how the scheme really works allows you to make decisions based on facts rather than assumptions.

Myth #2: Returning to the APS Won’t Improve an Existing PSS Benefit

The second misconception is common among former APS employees who preserved their PSS benefit when they left government employment.

Many believe their preserved benefit simply sits in a separate account until retirement and has little relationship with any future period of APS employment.

However, that’s not generally how PSS operates.

For many members who return to eligible employment and rejoin PSS, the preserved benefit is converted into a Preserved Benefit Multiple (PBM) which then forms part of the new PSS membership.

This is where things become particularly interesting.

What Happens When You Return to the APS?

When a former member rejoins PSS, the preserved benefit is converted into a Preserved Benefit Multiple.

The PBM is determined by dividing the preserved defined benefit by the commencing super salary of the new PSS membership. The PBM then forms part of the member’s overall benefit multiple going forward.

The member then accrues additional ABM through their new period of APS service.

At retirement, the PBM and ABM are combined and multiplied by the Final Average Salary applicable at that time.

What many people don’t realise is that the original preserved benefit effectively becomes embedded within the new membership calculation.

This means future salary growth may have a much greater impact than many former APS employees expect.

A Practical Example

Let’s assume an employee:

• Leaves the APS and preserves their PSS benefit.
• Returns to the APS several years later.
• Rejoins PSS.
• Continues working for another 10 years.

Assume their preserved benefit has grown to $500,000 and their commencing APS salary is $175,000.

Their Preserved Benefit Multiple would be:

PBM = $500,000 ÷ $175,000 = 2.857

Over the next 10 years they accrue a further:

ABM = 2.1

Through salary increases and promotions, their Final Average Salary eventually reaches:

$200,000

Their final defined benefit would broadly be:

FAS × (PBM + ABM)

$200,000 × (2.857 + 2.1)

≈ $991,400

The important point is not the exact dollar amount.

The real insight is that the preserved benefit doesn’t simply sit in isolation. Once incorporated into the new membership as a PBM, future salary growth can continue to influence the overall value of the benefit.

This is something many former APS employees are surprised to learn.

Could Returning to the APS Be More Valuable Than You Think?

We’ve seen cases where people dismiss opportunities to return to government employment because they assume the decision won’t meaningfully improve their existing PSS entitlement.

In reality, reconnecting with PSS can sometimes create a significantly better retirement outcome than expected, particularly when:

• The new role is at a higher classification.
• The member has many years remaining before retirement.
• The member expects further salary progression.
• The preserved benefit has already accumulated substantial value.

This doesn’t mean returning to the APS is always the best option.

It does mean the decision deserves proper analysis rather than assumptions.

The Bottom Line

PSS remains one of the most valuable and misunderstood superannuation schemes in Australia.

Before making decisions about part-time work, retirement or returning to government employment, it’s important to understand what actually drives your benefit.

If you’re considering part-time work:

• Your super salary generally continues to be based on your full-time equivalent salary.
• Going part-time primarily affects the growth of your Accrued Benefit Multiple, not your Final Average Salary.

If you’re considering returning to the APS:

• Your preserved PSS benefit may be converted into a Preserved Benefit Multiple when you rejoin PSS.
• Future service and salary growth may continue to enhance the overall value of your entitlement.

The difference between assumption and understanding can be worth hundreds of thousands of dollars over the course of a career.

At Bravium, we help APS employees understand the opportunities, risks and strategic decisions surrounding PSS, so they can make informed career and retirement choices with confidence.
