Super and the balance cap, explained

I was on the phone to my accountant last March, leaning against the kitchen counter, and I asked him the question I had been avoiding for two years. "How much do I actually have in super?" The number he read out was lower than I expected and the tax I had been paying on contributions was higher than I expected, and I realised I had been treating the whole system as a black box because I did not want to admit I did not understand the rules. That is the universal Australian experience with super. We assume someone in HR has it sorted. They do not. Nobody does. You have to.

This is the practical guide I wish I had read at 38. The numbers are current for the 2025 to 2026 financial year. The structure of the rules has been stable for about a decade now, so the framework will hold even if the dollar amounts get indexed up.

The three caps and why they exist

Super has three caps that interact, and the interaction is where most men get caught. Each cap is solving a different problem from the government's point of view.

• Concessional contributions cap: $30,000 per financial year. This is money going into super before tax (employer SG, salary sacrifice, personal deductible contributions). It gets taxed at 15 percent inside super instead of your marginal rate. Capped because the tax break is generous.
• Non-concessional contributions cap: $120,000 per financial year. This is money going into super after tax (you have already paid income tax on it). No further contribution tax. Capped because letting unlimited after-tax money in would turn super into a tax-haven trust.
• Transfer balance cap: $1.9 million. This is the lifetime limit on how much you can move from accumulation phase into retirement phase (where earnings are tax-free). Capped because the tax-free retirement phase is even more generous than the 15 percent accumulation rate.

Hitting all three is unusual but not rare. Plenty of professional men in their fifties on $250k-plus salaries, with a working spouse, an investment property they sold, and 25 years of compounding, will run into the transfer balance cap. The mid-career man's problem is usually the first two.

The concessional cap and the carry-forward rule

The $30,000 concessional cap includes your employer's compulsory super (currently 12 percent of salary on most arrangements). On a $180,000 salary, employer SG is around $21,600, leaving you $8,400 of headroom for salary sacrifice or personal deductible contributions before you breach the cap.

Here is the rule most blokes do not know. If your total super balance was under $500,000 at the end of the previous financial year, you can carry forward unused concessional cap from the previous five years. So if you contributed only the SG amount for the past five years, you might have $40,000 to $60,000 of unused cap sitting there waiting to be used.

This matters in two specific situations:

• The redundancy year. You get a payout, your taxable income spikes, and you can use accumulated carry-forward cap to drop tens of thousands into super in a single year and claim a tax deduction at your top marginal rate.
• The investment-property sale year. You realise a large capital gain, and a single chunky concessional contribution can offset some of the CGT.

Check your carry-forward balance in your myGov account under the ATO section. Do it now. The amount is often surprising.

The non-concessional cap and the bring-forward rule

The $120,000 non-concessional cap has a bring-forward provision: if you are under 75 and your total super balance is under $1.66 million, you can bring forward two years of cap and contribute up to $360,000 in a single financial year. The catch is that you cannot make further non-concessional contributions for the following two years.

This is the rule that matters when you sell a business, receive an inheritance, or settle a divorce property split. Getting a large lump sum into super in one go means decades of tax-advantaged compounding that you cannot recapture later. The mistake men make is to leave the lump sum in a joint savings account "for now" and then never get around to the contribution before the cap reduces or their balance crosses the threshold.

When salary sacrifice beats after-tax, and when it does not

The standard advice is "salary sacrifice is always better because the contribution tax is 15 percent and your marginal rate is higher." This is broadly true but not universally true.

Salary sacrifice is clearly better when:

• Marginal tax rate above 32.5 percent (taxable income over $45,000 in 2026). The differential between marginal rate and 15 percent contribution tax is real money.
• Stable income with no plans to access super before 60. The lock-up cost is low because you were going to leave the money there anyway.
• Concessional cap headroom available. Going over the cap means the excess gets taxed at your marginal rate plus an interest charge, undoing the benefit.

After-tax (non-concessional) contributions make more sense when:

• You have already maxed the concessional cap.
• You have a one-off windfall (inheritance, business sale, property sale) and want to shelter it.
• Your spouse has a much lower super balance and you want to spouse-split for the dual transfer balance cap benefit at retirement.

The most underused move is the personal deductible contribution. You contribute after-tax money during the year, then claim the deduction in your tax return. Functionally identical to salary sacrifice but more flexible because you do not have to pre-arrange it with payroll. Useful for contractors and the self-employed.

The Division 293 trap

Division 293 is the rule that catches high earners. If your taxable income plus concessional super contributions exceeds $250,000 in a financial year, your concessional contributions are taxed an additional 15 percent on top of the standard 15 percent contribution tax. Effective contribution tax becomes 30 percent.

For a man earning $260,000 with $25,000 of concessional contributions, the entire $25,000 is in Division 293 territory. The extra 15 percent is $3,750 a year. That is real money quietly leaving the system.

Division 293 still leaves salary sacrifice marginally better than taking the income (marginal rate of 47 percent including Medicare versus 30 percent contribution tax), but the gap narrows significantly. The honest analysis at that income level is whether the lock-up to age 60 is worth the 17-percentage-point spread. For most blokes the answer is yes, but it is closer than the standard advice suggests.

WORK OUT YOUR ACTUAL CONTRIBUTION TAX RATE. Most men assume 15 percent and run the maths from there. If you are in Division 293 territory, your number is 30, and your salary-sacrifice maths is overstated by half.

The transfer balance cap and why it matters before you retire

The $1.9 million transfer balance cap is the lifetime limit on moving super from accumulation phase (15 percent earnings tax) to retirement phase (zero earnings tax). Most men in their forties think this is a problem for future-them. It is, but the planning starts now.

If your trajectory points at a super balance well above $1.9 million by retirement (which on a 7 percent return and continued contributions, anyone with $700k now and 15 years to go is staring at), you have decisions to make:

• Spouse-splitting strategies. You can split up to 85 percent of your concessional contributions to your spouse each year. Two transfer balance caps in a household equals $3.8 million sheltered.
• Recontribution strategies. After 60, you can pull money out and recontribute it as non-concessional, converting it from a "taxable component" to a "tax-free component" for estate purposes. Useful if you intend to leave super to adult kids who would otherwise pay 17 percent death benefits tax.
• Outside-super investing. Above a certain threshold, the marginal dollar in super loses its tax advantage versus a personal name index fund (because the 15 percent earnings tax in accumulation, on a balance you cannot move into retirement phase, is no better than CGT discount on long-held shares).

The bullet-point summary

• Concessional cap $30k. Carry-forward unused if balance under $500k.
• Non-concessional cap $120k. Bring-forward $360k if balance under $1.66m.
• Transfer balance cap $1.9m lifetime, into retirement phase.
• Division 293 hits at $250k of taxable income plus contributions, doubles your contribution tax to 30 percent.
• Salary sacrifice usually wins, but not always, and not by as much as the standard advice claims.

Super is not magic. Super is a tax wrapper with three concentric caps and a half-dozen exceptions. The men who treat it like a black box pay extra tax for years and never realise. The men who spend two hours understanding the structure recover that time many times over.

Read your statement. Run the numbers. Use the caps.
