Division 296 and Defined Benefit Super: How CSS, PSS, DFRDB and MSBS Interests Are Valued

We’re Maciej Stanek and Imran Amjad, the financial advisers at Véurr Financial Planning. In one sentence: Division 296 counts a notional value for every defined benefit interest you hold — CSS, PSS, DFRDB or MilitarySuper (MSBS) — towards the $3 million threshold, attributes earnings to it by formula, and usually defers the tax on it until a benefit is actually paid. Most Division 296 commentary is written for accumulation-account audiences. This guide is for the Canberra households it skips: members of the closed Commonwealth and military schemes, whose “balance” is a formula, not a statement figure.

Does Division 296 apply to defined benefit super?

Yes. From 1 July 2026, Division 296 applies an additional 15% tax to super earnings attributable to the part of your total super balance above $3 million (a further 10% above $10 million) — and your total super balance includes your defined benefit interests, valued notionally.

The mechanics of the tax itself — the CPI-indexed thresholds, the realised earnings approach, the 30 June 2027 first test — are covered in the main explainer. What matters here is the scope rule: the ATO defines your total super balance (TSB) for Division 296 as the sum of the TSB values of all your Australian super interests. There is no defined benefit carve-out. CSC — the trustee of CSS, PSS, DFRDB and MilitarySuper — published its own Division 296 guidance in July 2026 confirming exactly this: defined benefit interests are included in both the balance test and the earnings calculation, so they can be “counted alongside any other super you hold”. A long-serving PSS officer, or a DFRDB retiree with a PSSap account from later service, can be inside Division 296 territory without ever seeing a seven-figure statement — the threshold is tested against everything, combined.

The exceptions are a short, specific list — and the ATO draws a distinction worth keeping, because most summaries collapse it. Some people are excepted from the tax. Separately, some earnings are excluded from it. In the ATO’s own words:

Individuals excepted from Division 296 tax. “You are excepted from paying Division 296 tax if you: are a child recipient of a super income stream at any time during the income year; are an individual who has received a structured settlement contribution made to you as a payment for a personal injury, in the income year, or any earlier income year; or die in the 2026–27 income year.”

Super earnings excluded from Division 296 tax. “There are rules for specific super earnings excluded from Division 296 tax, for: State higher level office holders and their reversionary pension recipients; Commonwealth justices and judges and their reversionary pension recipients; Territory Supreme Court judges and their reversionary pension recipients; individuals with super interests in foreign super funds; individuals with super interests in non-complying super plans.”

Two details are easy to lose. A judge is not an excepted person — it is the earnings on those particular interests that are excluded, so other super interests remain within Division 296. And the structured-settlement exception reaches back to a contribution made “in the income year, or any earlier income year”, not only the current one.

How is a defined benefit interest valued for the $3 million cap?

Your defined benefit interest is assigned a “TSB value” under valuation rules prescribed by regulations made in June 2026 — not by anything you calculate yourself. Your scheme works out the value and reports it; CSC describes these as “specific valuation methods rather than a single formula”.

Here is the honest state of play. The 2026 law changed how total super balance is defined and introduced a total super balance value for each interest, with the detailed valuation rules sitting in the supporting regulations — the Building a Stronger and Fairer Super System Regulations 2026, in force since June 2026, which contain a dedicated schedule on total superannuation balance value and a schedule of valuation parameters. What has not been published is a plain-English, member-level walkthrough of how those parameters apply to a CSS pension multiple or a PSS accrued benefit multiple — the ATO is still drafting a Law Companion Ruling. Until that lands, be sceptical of any article, or any AI answer, quoting a neat universal formula for what your defined benefit is “worth” under Division 296. The practical reality for members:

• You don’t calculate the value — your scheme does, and reports it to the ATO along with your other interests.
• You can see the combined result through ATO online services via myGov.
• Don’t rely on a point-in-time CSC balance alone to judge whether Division 296 applies to you — that caution comes from CSC itself.
• If a reported value looks wrong, the query goes to the fund that reported it — the ATO can only amend an assessment after the fund amends its reporting.

And keep it distinct from the Transfer Balance Cap ($2.1 million for 2026-27): its special value rules for defined benefit pensions are a different measure entirely, and figures from one cannot be assumed to carry over to the other. Our superannuation advice hub covers the caps side by side.

How are earnings calculated on a defined benefit interest?

For defined benefit interests not yet in retirement phase (and certain other prescribed interests), your fund calculates “relevant super earnings” from the change in the interest’s TSB value over the year, under a specific formula that adjusts for contributions and withdrawals — not from investment returns you actually receive.

This is the second place defined benefit members are treated differently: as CSC puts it, earnings “may be attributed to your interest even without a visible account balance, reflecting how benefits accrue”. In a year your notional value rises — another year of service, a salary movement, the valuation parameters themselves — that movement can show up as earnings for Division 296 purposes.

Once every fund has reported, the ATO adds your relevant super earnings together, works out what proportion of your TSB sits above the threshold, and taxes that proportion of earnings — the step-by-step arithmetic, with worked examples, is on the ATO’s calculation page. On timing: the ATO will start asking funds that use the defined benefit formula for this information in November 2027, with first assessments for 2026-27 issuing in the later half of the 2027-28 income year. Nobody receives a Division 296 bill on 1 July 2026 — but the year being measured has already started.

When do defined benefit members actually pay Division 296 tax?

Usually much later than everyone else. Where Division 296 tax relates to a defined benefit interest from which no end benefit has yet been paid, that portion is automatically deferred to a Division 296 deferred debt account — falling due 21 days after an end benefit becomes payable, though interest accrues and you can pay earlier by choice.

This deferral is the piece of the design built for people whose super cannot be dipped into: you generally can’t withdraw from CSS, PSS, DFRDB or the MSBS employer benefit to settle a tax bill. The mechanics, from the ATO’s defined benefit guidance:

• The split is automatic and proportionate. The deferred portion is your Division 296 tax for the year multiplied by your defined benefit earnings as a share of your total super earnings; tax attributable to accumulation interests stays on the normal 84-day timeline.
• One debt account per interest. The ATO creates a separate deferred debt account for each defined benefit interest you hold, and sends a statement whenever the balance changes.
• Interest accrues annually. Deferred debt unpaid at 30 June each year incurs interest at the long-term bond rate for that financial year, calculated on the balance including previous years’ interest. Paying voluntarily by 30 June avoids that year’s charge.
• You can clear it early. With your own money at any time, or by electing — within 60 days of your notice of assessment — to release money from another super interest, such as PSSap or another accumulation account. Most defined benefit funds cannot release amounts before an end benefit, so check before electing.
• The end point is the end benefit. Generally the first super benefit to become payable from the interest — retirement, resignation, death, disability or a scheme maximum age. The deferred debt is then due within 21 days, and a release authority can at that point go to the defined benefit fund itself. Successor fund rollovers, severe financial hardship and compassionate release, and family law super payments do not count as end benefits.

The planning question this creates is genuinely new: deferring for years trades cash-flow relief now against a compounding debt that arrives alongside your retirement decisions. Which setting is better depends entirely on your circumstances — a decision to model with a licensed adviser rather than default into.

How does Division 296 land on CSS, PSS, DFRDB and MilitarySuper?

All four CSC-administered schemes are inside the net, but they present differently: CSS and MilitarySuper are hybrids with accumulation and notional components, PSS is a formula-defined benefit, and DFRDB is a pure defined benefit with a lifetime pension after more than 20 years’ effective service. Each interest gets its own TSB value and, if deferred, its own debt account.

Three scheme-specific observations. First, Defence members frequently hold multiple interests — retirement pay plus an ancillary account plus ADF Super or PSSap from later service — and Division 296 is assessed across the combined set, with the deferral rules applying per interest (see our DFRDB and MSBS guide and the DFRDB commutation framework). Second, CSC has flagged that special rules apply to certain pensions, including military invalidity income streams — if you receive one, treat every general statement on this page as needing a scheme-specific check. Third, for CSS and PSS members the biggest lever is timing — the same conclusion our public servants guide reaches from the scheme side.

What should defined benefit members do before 30 June 2027?

The first test date is 30 June 2027, and some settings cannot be adjusted once a financial year has closed. Five steps, in order:

1. Check your total super balance across every interest. Log in to ATO online services via myGov and check your reported total super balance across all interests. Do not rely on a point-in-time scheme balance alone.
2. Understand what your defined benefit interest is contributing. If the combined figure is anywhere near $3 million, find out how much is the notional defined benefit value. Queries about a reported value go to the scheme that reported it.
3. Review timing decisions before locking anything in. Pension activation, resignation and commutation decisions all change how your interests are valued and taxed. Options are widest before a benefit is locked in – model first, decide second.
4. Plan how any Division 296 liability would be paid. Decide in advance whether you would let a deferred amount compound, pay it down voluntarily each year, or release money from an accumulation interest within the 60-day election window.
5. Take licensed financial advice on the whole position. Division 296 interacts with the Transfer Balance Cap, scheme rules and your broader retirement plan – a licensed adviser who works with Commonwealth and military schemes can model the moving parts together.
