PSS pension, lump sum or both: how your benefit converts, and the choices you can’t undo

We’re Maciej Stanek and Imran Amjad, financial advisers at Véurr Financial Planning in Canberra. This page explains how the Public Sector Superannuation Scheme (PSS) pays out, in general terms. It is not a recommendation to take a pension, a lump sum or any mix of the two: that depends on your health, your other income, your family and your plans. If you’re in CSS rather than PSS, the rules are different; our guide to the CSS 54/11 strategy covers one of them.

What PSS is working out for you

PSS opened on 1 July 1990 and closed to new members on 30 June 2005. It is a defined benefit scheme: while you contribute, your benefit is set by a formula, your Final Average Salary multiplied by your Accrued Benefit Multiple, not by investment returns. CSC describes Final Average Salary as typically the average of your last three reported super salaries, and the multiple builds up with your contribution rate, your length of service and your hours (CSC, about PSS).

That benefit is the amount you are deciding about. The choice is what form it takes when you claim it.

Which options are open depends on your age and whether you’ve retired

• From 55, if you have permanently retired. You can generally take a pension. CSC treats you as permanently retired if you are not gainfully employed for more than 10 hours a week.
• Before your preservation age. The cash you can take as a lump sum is restricted; CSC calls the limit your SIS upper limit. For anyone born on or after 1 July 1964, which includes everyone under 62 today, preservation age is 60 (CSC, when can I retire).
• From preservation age, once retired. You can take your whole benefit as a pension, a lump sum or a combination of both.
• Not ready yet. You can leave the whole benefit preserved in PSS and claim it later, but no later than 65. While it is preserved, your member and productivity components earn investment returns and the employer-financed part is adjusted each year for upward movements in the CPI.

Leaving through a redundancy, or on invalidity grounds, follows separate rules. Our guide to taking a redundancy at 60, 65 or past Age Pension age covers the tax and super side of a late-career redundancy.

How does CSC work out a PSS pension from your benefit?

CSC divides the amount of your PSS defined benefit that you choose to convert by a pension conversion factor. The factor depends on your age, in years and days, on the day you claim. It is 12 at age 55 and falls by 0.2 for each year of age, to 11 at 60 and 10 at 65, so the same amount converted buys a larger starting pension the later you claim.

Here is CSC’s published table, with one column added: what each $100,000 of defined benefit converted would pay in the first year at that age. That is the division and nothing else, before tax and before any indexation.

Factors: CSC, accessing your PSS benefit, retrieved 20 October 2026. CSC’s table is in whole years; the factor it applies is based on your age in years and days on the day you claim. Factors after 65 and three months apply only if you are still contributing; a preserved benefit not claimed by then may only be paid as a lump sum.

One way to read the factor: it is also the number of years of payments at the starting rate that add up to the amount converted. At a factor of 11, that is 11 years. It leaves out indexation, tax, what a lump sum might have earned instead, and how long anyone actually lives, which are exactly the things that make the decision personal.

Can you take part of your PSS benefit as a lump sum and the rest as a pension?

Yes, within limits. Once you have reached your preservation age and permanently retired, at least half of your defined benefit has to be converted to the pension, so the lump sum part can be no more than 50%. Before preservation age, whether a mix is open depends on whether you are still contributing, have preserved your benefit or joined PSS before 1 July 1999, and any cash you take is capped at your SIS upper limit. Your CSC benefit estimate shows what applies to you.

Can you take your whole PSS benefit as a lump sum?

Often, but the conditions depend on your age and on whether you are still contributing or have preserved your benefit. The lump sum is paid once, as your benefit’s three components: member, productivity and employer. Under 60 you generally have to be permanently retired, and before your preservation age the part you can take as cash is capped at your SIS upper limit; the rest generally has to go to another super fund until you meet a condition of release. Your CSC benefit estimate shows what applies to you.

Is a PSS pension indexed?

Yes. CSC adjusts pensions on the first payday in January and July each year, after the Australian Bureau of Statistics releases the Consumer Price Index, and increases them only when the CPI has gone up. The July 2026 increase was 2.0%.

CSC describes it as a lifetime fortnightly indexed pension (CSC, about PSS). A lump sum has no indexation of its own: what it is worth later depends on where it goes and how it is invested.

What else differs between the two

If you die while receiving a PSS pension, CSC pays benefits to your eligible spouse and/or children; how much, and in what form, is set out in CSC’s death and invalidity information.

Tax differs too. CSC’s page on tax and your defined benefit explains that from age 60 the part of a pension from a taxed source is tax-free, and the part from an untaxed source (your unfunded employer benefit and any pre-July 1990 productivity and fund earnings) is taxed at your marginal rate plus the Medicare levy, less a 10% offset. Those concessions stop at the defined benefit income cap, $131,250 a year for 2026–27 (ATO, Table 27): above it, 50% of the taxed-source amount over the cap counts as assessable income, and untaxed amounts over the cap get no 10% offset. A lump sum taken from 60 is taxed differently again: CSC lists the untaxed part at 15% plus the Medicare levy, up to the untaxed plan cap. Your accountant or the ATO can confirm how either option would be taxed for you.

Three ways the pension option closes

1. Taking part as a lump sum and preserving the rest. CSC says that if you take less than your full benefit as a lump sum and preserve the balance, you will not be able to take that balance as a pension later.
2. Missing the deadline after 65. A preserved benefit must be claimed by 65. If it is not claimed within three months after your 65th birthday, CSC says it may only be paid as a lump sum.
3. Having already taken part of it as a preserved member. For a preserved member, the full-pension and part-pension options are available only if you did not access part of your benefit when you stopped contributing or while it was preserved.

Each of these is a rule CSC applies, not a judgement about which option suits anyone (CSC, accessing your PSS benefit).

What to have in front of you before you decide

• A current personalised benefit estimate, which you can generate on CSC’s website.
• Your other income in retirement, including any other super and whether you might receive the Age Pension.
• Your health, your partner’s situation and what you would want to leave behind.
• How each option would be taxed for you, confirmed by your accountant.
