Defined benefit super: start with the choice that can’t be undone.

A defined benefit is worked out by a scheme formula, not by adding up contributions and investment returns. ASIC’s Moneysmart says the formula usually considers the money you and your employer put in, your average salary over the last few years before retirement, and how long you worked. These accounts are less common: they’re only open to certain workers, or they no longer take new members. Your scheme’s current rules and official estimate are the starting point.

In an accumulation account, your balance grows or falls with contributions and investment returns, minus fees. In a defined benefit, a formula sets the payout, so market moves have a limited effect on the main benefit. Moneysmart says some defined benefit accounts provide very generous benefits, so get advice before leaving one — and if you leave, you generally can’t rejoin.

Only if your scheme rules allow it, and even then it’s often a one-way door. Moneysmart says some funds offer benefits you lose if you leave, and you generally can’t rejoin. Some schemes let you roll out part of the benefit, or an accumulation slice sitting beside it; others won’t let you transfer the whole defined benefit at all. Confirm what your administrator will actually permit before you treat a rollover as an option.

Your fund uses its own formula. ASIC’s Moneysmart shows a simplified example: average salary for the last three years, multiplied by years of service, multiplied by a benefit factor — so $100,000 times 20 years times 0.15 equals $300,000. Your scheme may use different factors, including your age at retirement and any contributions you made. Ask the administrator for an official estimate at more than one date if timing is part of the decision.

Defined benefit pensions follow different tax rules to account-based pensions. Before you can access the benefit, your fund sends a statement showing how much is taxable and how much is tax-free. For most taxed funds, income from a super income stream is usually tax-free from 60. Some public sector schemes are untaxed, so the untaxed element stays assessable after 60, with a 10% tax offset that the ATO limits using the defined benefit income cap — $131,250 for 2026–27.

54/11 is a CSS election. CSC says it means resigning at least two calendar days before your 55th birthday, electing to preserve the CSS benefit within 21 days of finishing, then claiming a deferred benefit on or after you turn 55. The deferred benefit is calculated differently from ordinary retirement at or after 55. Members aged 55 and over who leave through redundancy can also use the deferred-benefit method. It’s a dated, one-way door — get estimates for both routes before the window closes.

Some elections are difficult or impossible to reverse after they take effect. Moneysmart says if you leave a defined benefit you generally can’t rejoin, and a lifetime income stream usually can’t be changed once it has started. Check the current scheme rules and get advice before you act where the decision is permanent.
