Division 296: the $3m super cap and what FIRE planners need to know

Division 296 is the new label for the tax that has been described, debated and redrafted under several names since 2023: the “Better Targeted Superannuation Concessions” tax, the “$3 million super cap”, the “unrealised gains tax” (in early drafts) and, in plain language, an extra 15% on top of the 15% already charged on super earnings, applied only to the slice of your fund balance above $3 million. The legislated form takes effect from 1 July 2026 for the FY2026-27 income year onward. The ATO summarises the operating rules on its Division 296 reference page.

Who actually pays this

Treasury's impact modelling estimated fewer than 80,000 Australians would have a Total Super Balance above $3 million when the tax first commences. That is roughly 0.5% of super members. The cohort skews older, with a long right tail of high-balance Self-Managed Super Funds accumulated under earlier, more generous contribution caps. The median Australian retiring in 2026 with a balance somewhere between $200,000 and $500,000 will never encounter Division 296.

For FIRE planners the picture is different. The fat-FIRE cohort, by definition, targets a wealth base that funds a lifestyle north of $150,000 a year forever. Even at a 3% safe withdrawal rate that implies $5 million of total wealth. If half of that sits inside super, the household is squarely in Division 296 territory the moment two accumulation balances each cross $1.5 million. A high- earning couple front-loading concessional contributions and the maximum bring-forward non-concessional cap can plausibly hit that point in their late 40s.

Even outside the fat-FIRE persona, two situations bring the threshold into play earlier than people expect:

• Single-earner households where one partner has carried all the concessional and bring-forward contributions for two decades.
• Households that received a large in-specie contribution before the contribution-cap reforms of the 2010s, often a business sale rolled into super.

How the math actually works

Division 296 taxes a proportion of your super earnings, not your whole balance. Four steps:

• Total Super Balance test. The ATO takes your TSB at 30 June each year. TSB sums every super interest you hold across every fund, accumulation and retirement phase, including amounts above your personal Transfer Balance Cap that stay in accumulation.
• Calculate the proportion above $3 million. (TSB minus $3,000,000) divided by TSB. At $4m TSB the proportion is 25%. At $5m it is 40%. At $10m it is 70%.
• Calculate earnings for the year. The ATO defines earnings as the change in TSB across the year, adjusted for net contributions in (subtract) and net withdrawals out (add back). This calculation matches the conceptual definition used in the legislation itself.
• Apply the 15% rate to the proportion. The Division 296 liability is 15% multiplied by the earnings figure multiplied by the proportion above $3m. The liability is raised against you personally, not against the fund, and you can elect to pay it from inside super using a release authority.

Worked example: a $4 million SMSF earning 7%

Take a single member with a Total Super Balance of $4 million on 1 July 2026, no contributions or withdrawals during the year, and a 7% nominal return.

The headline is the last row. The marginal earnings on the slice above $3m carry a 30% effective tax rate, double the usual 15% that super members pay in accumulation. The first $3m of earnings stays at 15%.

The unrealised-gains debate, and where it landed

The original draft of this tax, introduced into Parliament in late 2023, defined earnings as the change in TSB across the year. Mechanically that includes unrealised capital gains: a property held inside an SMSF that rose in valuation during the year would contribute to taxable earnings even if no asset was sold and no cash changed hands. That mechanic drew significant pushback from actuaries, SMSF advisers and parts of the cross-bench. The common objections:

• Funds holding lumpy illiquid assets (farms, business real property, unlisted shares) could face a tax bill on paper gains with no cash to pay it.
• Year-to-year volatility in asset valuations would translate directly into volatile tax liabilities.
• A subsequent fall in value would generate a deduction or carry-forward loss but never a refund of tax already paid, creating an asymmetry across cycles.

The version that passed the Senate and received Royal Assent retains the TSB-change definition for the calculation but pairs it with carry-forward loss provisions and an option to pay the liability from outside super. SMSF members can also elect to pay the liability from inside the fund via a release authority, in the same mechanical pattern used for Division 293 excess concessional contributions.

Indexation: the $3m threshold may or may not move

Concessional and non-concessional contribution caps index with Average Weekly Ordinary Time Earnings (AWOTE) in $2,500 and $5,000 steps respectively. The Transfer Balance Cap indexes with CPI in $100,000 steps. The $3 million Division 296 threshold, by contrast, was legislated as a fixed dollar amount with no indexation mechanism in the Act. Reporting around the bill's passage suggested future indexation would be considered as part of the regular tax-system review cycle, but the current law contains no automatic mechanism.

For a 30-year FIRE planner that matters enormously. If inflation averages 2.5% across the next 25 years, $3 million in 2026 is worth $5.6 million in 2051. Without indexation the cap pulls in steadily more members over time, a phenomenon sometimes called bracket creep. A balance that comfortably clears the threshold today may be partially exposed two decades later even with no real wealth growth.

Plan on the basis of current law, but treat any forecast of the threshold value beyond five years as politically contingent.

Planning response for FIRE planners approaching $3m

Once your trajectory has you crossing $3m, the marginal decision becomes: where do I park the next dollar?

Slow concessional contributions inside super

For income earners below the Division 293 high-income threshold of $250,000, concessional contributions are taxed at 15% inside super versus a marginal 30%, 37% or 45% if taken as salary. The arbitrage that has powered FIRE super strategies for two decades is still real. Above $3m, however, the future earnings on those contributions face 30%, not 15%. The arbitrage compresses but does not vanish: 15% in versus 30% on growth still beats 30% in plus 22% to 23% effective on growth outside super (45% marginal less the 50% CGT discount) for someone on the top marginal rate.

The clear loser is voluntary non-concessional contributions once TSB approaches $3m. Money that is already taxed at marginal rates, contributed in post-tax, then locked behind preservation rules to face Division 296 on the slice above the cap, has very little to recommend it relative to a non-super investment with full liquidity and the 50% CGT discount.

The TSB-based contribution caps already restrict non-concessional contributions once your TSB approaches the Transfer Balance Cap. Division 296 reinforces the signal: stop pushing more in.

Redirect surplus to non-super wealth

For a high-marginal-rate earner targeting fat-FIRE, the comparison once TSB is above $3m looks something like this:

The bottom row is the relevant comparison once TSB has crossed the threshold. Long-term earnings outside super, with the 50% CGT discount, often face a slightly lower effective rate than inside-super earnings on the Division 296 slice. Add the liquidity advantage, and the case for directing surplus to a non-super broker account becomes meaningfully stronger.

Couples: split the balance across two members

Division 296 applies per member, not per household. A couple with $5 million of combined super split evenly into $2.5 million each sits below the threshold and pays no Division 296. The same $5 million held entirely in one partner's account leaves $2 million exposed to the 30% effective rate on its earnings.

Mechanisms to balance super between partners include contributions splitting (up to 85% of the prior year's concessional contributions can be split to a spouse, usually annually) and spouse contributions. Both are long-cycle levers; they cannot move a meaningful balance in one year, but compounded over a decade they reshape the Division 296 exposure of the household considerably.

Time the start of pension phase deliberately

Division 296 applies to TSB whether it sits in accumulation or retirement phase. Starting an account-based pension does not move you below the threshold; only an actual reduction in TSB does. The practical levers are:

• Drawing the statutory minimum pension once in retirement phase reduces TSB each year, slowing the compounding rate at which the slice above $3m grows.
• For balances well above $3m, drawing materially more than the minimum (or recontributing the surplus to a partner's account, subject to TSB caps) shifts wealth out of the Division 296 zone.
• Withdrawing from super after preservation age and investing in your personal name converts the future tax treatment from 30% on the slice above $3m to ~22-23% long-term plus immediate liquidity. For households well past their FIRE number this is often the cleanest move.

What Division 296 doesn't change

It is easy to read coverage of this tax and conclude that super is broken. It is not.

• Concessional contributions remain the most tax-efficient way to convert earned income into invested wealth for anyone earning above $45,000 with TSB below $3m. That is the overwhelming majority of working Australians.
• The 15% tax on super earnings below $3m is unchanged. The 50% CGT discount inside super (33.3% effective rate on long-term realised gains) is unchanged. Franking credits inside super are unchanged.
• Retirement-phase earnings on the first $2.1m (the Transfer Balance Cap from 1 July 2026) remain tax-free. That benefit dwarfs the Division 296 cost for most retirees.
• Bridge strategies between FIRE age and preservation age do not change. Non-super wealth still funds the bridge years regardless of what is happening on the super side.

Pre-FY2026-27 checklist for high-TSB planners

• Confirm your 30 June 2026 TSB across every super interest you hold. If you have legacy funds, check the ATO super reporting in myGov to ensure none have been missed.
• If TSB is within ~$200,000 of $3m, decide whether additional FY2026-27 non-concessional contributions still make sense. For most planners in that band, the answer becomes no.
• If TSB is well above $3m, model the impact of moving surplus future contributions to a non-super broker account using current 50% CGT discount math. Then re- model using the post-1-July-2027 indexation regime to see which side of the 2027 CGT changeover the decision actually sits.
• For couples, run the projection with and without contribution splitting to see how much Division 296 exposure can be flattened by rebalancing across both accounts over the next decade.
• Set a calendar reminder to revisit the ATO Division 296 page each March before the year-end planning window. The unrealised-gains element and the indexation question are the two areas most likely to see legislative amendments.

Bottom line

Division 296 doubles the tax rate on a defined slice of your super wealth from 1 July 2026. It only affects you once your Total Super Balance crosses $3 million. For most FIRE planners it is academic. For the fat-FIRE cohort it rebases the marginal-dollar decision: future contributions and accumulated earnings on the slice above $3m now face 30%, comparable to (and sometimes worse than) the long-term tax rate on the same dollars held outside super. The fix is not to abandon super, it is to stop adding more to it once your TSB is approaching the threshold, balance the household across both partners, and direct the next marginal dollar to wherever it gets the best long-run after-tax outcome.
