Super $3M balance cap — demystified

Does this affect me?

For 95% of Australians — no. This only bites if your total super balance is above $3 million. If you're a regular worker with a regular super account, nothing changes for you. If you're a low-income earner, you actually get more into your super via LISTO.

Quick test:

• Check your super balance (log into your fund or myGov). Under $3M? Zero impact.
• Earn under ~$45,000 a year? LISTO gives you a bigger super top-up from 1 July 2026.
• Got multiple super accounts? It's your total balance across all of them that counts.
• Run a self-managed super fund (SMSF)? Same rules apply — no free pass.

TL;DR

The $3 million superannuation balance cap was legislated via the Treasury Laws Amendment (Building a Stronger and Fairer Super System) Act 2026 (Royal Assent 13 March 2026). Concession reductions apply only to total super balances above $3 million — affecting roughly the top 5% of super account holders. The Low Income Superannuation Tax Offset (LISTO) was simultaneously increased, reaching 1.3 million Australians. The 2026-27 Budget finalises the parameters and adds $20.0 million in extra receipts over five years from 2025-26.

Anyone claiming "Labor is taxing all super at 30%" is wrong. The change targets the top 5%; the bottom 30% of earners get more concession via LISTO.

Jargon decoder:

• Super (superannuation) = your retirement savings account. Your employer pays in 11.5%+ of your wage; you can't usually touch it until you retire.
• Total Super Balance (TSB) = the combined value of all your super accounts on 30 June each year — checked by the ATO.
• Concessional rate = the discounted 15% tax rate that applies to super (vs your normal income tax rate). It's the "concession" the government gives you for locking money away until retirement.
• LISTO (Low Income Super Tax Offset) = a government top-up that refunds the 15% contributions tax for low earners — basically extra money into your super if you're on a low wage.
• SMSF = Self-Managed Super Fund. A super fund you run yourself instead of a big industry/retail fund.

What's NOT in this budget

• A new tax on super contributions for everyone.
• A 30% earnings tax across all super balances — only above $3M.
• Forcing pre-1985 super to be re-taxed.
• Removal of the 15% concessional tax rate on contributions below the cap.
• A wealth tax on assets outside super.

What IS in this budget

The headline numbers

How the cap actually works

• Applies to Total Super Balance (TSB) above $3M (not just one account).
• Earnings on the portion above $3M are taxed at an additional rate on top of the existing 15% concessional rate.
• Indexed (parameters confirmed in this budget — index methodology in the Act).
• Calculated annually on 30 June TSB.
• Reported via the ATO; payable individually via personal tax return or by the super fund (election).

What about LISTO

• LISTO refunds the 15% contributions tax for low earners.
• The increase under the same legislative package boosts the refund amount + raises the income threshold.
• 1.3 million low-income earners now get more in retirement savings via this offset.

Key dates

Worked example — Linda, age 58, $4M TSB

• TSB at 30 June 2026: $4,000,000.
• Portion above threshold: $1,000,000.
• Notional earnings on that portion (assume 5%): $50,000.
• Additional tax (15%): ~$7,500 (illustrative — actual mechanism varies).
• The portion below $3M continues to enjoy the standard 15% concessional rate on earnings.

Worked example — Jake, age 38, $250k TSB

• Nowhere near the cap. Nothing changes.
• If Jake earns under the LISTO threshold he receives a higher refund of the 15% contributions tax than before.

Worked example — Joanne, age 60, $800k TSB + casual income

• Casual hospitality income, under the LISTO income threshold.
• Pre-change LISTO: ~$500/year refund.
• Post-change LISTO (higher boundaries): meaningful uplift — many hundreds more per year going into her super.

Myths vs reality

Myth 1: "Government is taxing all super savings" — FALSE

Only the portion above $3M Total Super Balance is hit. The bottom 95% are untouched (and many gain via LISTO).

Myth 2: "It's a flat 30% tax across the board" — FALSE

Existing 15% rate stays for balances under $3M. The "30%" figure people repeat is an additional tax on the earnings of the portion above $3M, not a 30% slap on every dollar.

Myth 3: "Self-managed super funds are exempt" — FALSE

The cap applies to TSB regardless of fund type (APRA-regulated fund, SMSF, defined benefit). SMSFs are not a workaround.

Myth 4: "Pre-1985 assets re-taxed" — FALSE

The cap applies to forward earnings on the portion above $3M, not to historical asset cost bases.

Myth 5: "Defined benefit funds escape" — MISLEADING

There's a specific methodology for defined benefit interests (notional contribution methodology). They don't escape — they have their own calculation.

Myth 6: "It's not indexed so eventually it'll hit everyone" — CHECK ACT

The legislated package includes parameters for indexation. The methodology is in the Act, not removed by this budget.

Myth 7: "Farmers lose their farm to pay this" — FALSE

The cap applies to super balances, not to operating businesses or farms held outside super. Farmland inside SMSFs in pension phase has its own treatment but isn't compulsorily liquidated by this measure.

Myth 8: "LISTO is being cut" — FALSE

LISTO is increased. 1.3 million Australians get a bigger refund.

Myth 9: "Contributions caps are also being slashed" — FALSE

Standard concessional ($30,000) and non-concessional ($120,000 / 3-year bring-forward $360,000) caps are unchanged in this measure.

Myth 10: "The receipts ($20M over 5 years) prove it raises nothing" — MISLEADING

The $20M is the additional receipts the 2026-27 budget adjustments raise above the MYEFO 2025-26 baseline. The total revenue impact of the policy is much larger — it's captured at MYEFO, not double-counted here.

But what if...

...I'm not near $3M now, but might be by retirement? The cap is indexed (see Myth 6) — meaning the $3M threshold rises over time with inflation/wages, so the bar moves up as your balance grows. If you're on track to hit it, you've got runway to plan. Check your projected balance with your fund's retirement calculator or Moneysmart's super calculator.

...should I move money out of super to dodge this? Probably not worth it for most people. Super is still the lowest-taxed wrapper in the system — 15% on earnings below $3M beats your marginal income tax rate (up to 45%) almost every time. Get advice before pulling money out; the tax saved outside super rarely beats what you'd lose by leaving the concessional rate.

...what about my SMSF? Same rules. Your SMSF balance counts toward your Total Super Balance just like an industry fund. No workaround. If your SMSF holds illiquid assets (property, farmland) and you're over $3M, talk to your accountant about liquidity — the extra tax bill is calculated on notional earnings, so you might need to free up cash to pay it.

...my partner and I have $2M each — are we hit? No. The cap is individual, not household. Two people on $2M each are both well under. (This is one reason couples often split contributions across both names.)

...I'm already retired and drawing a pension from super — am I affected? Only if your remaining Total Super Balance is above $3M. The cap looks at your balance on 30 June each year, regardless of whether you're in accumulation or pension phase.

...do I have to do anything to claim LISTO? No — it's automatic. The ATO works it out from your tax return and your super fund details, and pays it straight into your super account. Just make sure your fund has your tax file number.

Where genuine debate lives

1. Whether the threshold should be lower ($2M) or higher ($5M) — strikes the policy balance differently.
2. Whether indexation should be inflation, AWOTE, or something else.
3. Defined benefit calculation methodology — is it fair across schemes?
4. Whether SMSF liquidity issues warrant transitional provisions for farms/businesses held in fund.

A useful filter

1. Under $3M TSB? No change.
2. Above $3M? Additional tax on earnings of the portion above $3M.
3. Low-income earner? LISTO is better now.
4. Super or non-super wealth? This is super-only.
