Key Takeaways

  • A layered approach to super contributions — combining employer SG, salary sacrifice, and personal contributions — can significantly lift your retirement balance.
  • The carry-forward rule allows members with balances under $500,000 to use up to five years of unused concessional cap in a single year.
  • The bring-forward rule enables eligible members to contribute up to $390,000 in non-concessional contributions in a single year from 1 July 2026.
  • Tax considerations — including Division 293 for high earners and LISTO for lower earners — affect which strategies are most effective for each individual.
  • Strategic timing of contributions around the end of the financial year and major life events can maximise their impact.

Getting Serious About Super in 2026

For many Australians, superannuation happens to them rather than being something they actively manage. Their employer makes the Superannuation Guarantee contribution — 12% of ordinary time earnings since 1 July 2025 — and the money disappears into a fund, rarely thought about until retirement approaches.

This passive approach has a cost. The ASFA Retirement Standard puts a comfortable retirement for a single homeowner at around $54,240 per year, backed by a lump sum of approximately $595,000. For a significant proportion of Australians, employer contributions alone will not reach that figure. Superannuation law provides a range of contribution strategies that, used intelligently, can substantially close the gap.

The Two Types of Contributions

Concessional contributions are before-tax contributions taxed at 15% inside the fund. They include employer SG payments, salary sacrifice, and personal contributions you claim as a tax deduction. The concessional cap is $30,000 in 2025–26, rising to $32,500 from 1 July 2026.

Non-concessional contributions are after-tax contributions not taxed going in (up to the cap), with earnings inside super taxed at 15%. The non-concessional cap is $120,000 in 2025–26, rising to $130,000 from 1 July 2026. Both caps are enforced by the ATO, and exceeding them triggers additional tax.

Strategy 1: Salary Sacrifice to the Cap

Salary sacrifice is the most widely accessible concessional contribution strategy. You arrange with your employer to direct a portion of pre-tax salary into super, where it is taxed at 15% rather than your marginal rate. Subtract your employer's SG contributions from the concessional cap to calculate the available space. For a worker earning $100,000 with an employer contributing 12% ($12,000), that leaves $18,000 available for salary sacrifice in 2025–26.

Salary sacrifice works particularly well for those in the 32.5% or higher marginal tax brackets. For those earning above $250,000, Division 293 tax applies an extra 15% on concessional contributions, but salary sacrifice still provides advantages — particularly the concessional rate on earnings inside the fund.

Strategy 2: Personal Deductible Contributions

Self-employed Australians and those unable to use salary sacrifice can make personal contributions from their bank account and claim a tax deduction in their tax return — up to the concessional cap. The tax outcome is equivalent to salary sacrifice. You must lodge a "notice of intent to claim a deduction" with your fund before lodging your return.

Strategy 3: The Carry-Forward Rule

The carry-forward rule allows members with a total super balance below $500,000 to access unused concessional cap space from the previous five financial years. This is particularly relevant for Australians who have had interrupted careers — through caregiving, study, illness, or variable income — and who now have capacity to save more. Rather than being constrained by the annual cap, they can make a single large concessional contribution using accumulated unused space. The available carry-forward amount is visible through your ATO account via myGov.

Strategy 4: Non-Concessional Contributions and the Bring-Forward Rule

For those with after-tax savings to deploy — from a property sale, an inheritance, or accumulated savings — non-concessional contributions are an effective way to move money into the tax-advantaged super environment. Eligible members can trigger the bring-forward rule, combining up to three years' worth of cap into a single year. From 1 July 2026, the maximum bring-forward amount is $390,000, provided the member meets eligibility requirements including total super balance thresholds.

Strategy 5: Spouse Contributions

Contributing to a lower-earning spouse's super can be tax-effective in two ways: you may be eligible for a tax offset, and you can help equalise balances between partners — which is strategically valuable from a tax and pension planning perspective in retirement. You can also split concessional contributions with a spouse, directing up to 85% of your concessional contributions to their account, subject to their age and contribution rules.

Strategy 6: LISTO and Government Co-Contribution

The Low Income Superannuation Tax Offset (LISTO) refunds up to $500 of the 15% contributions tax paid on concessional contributions for those earning up to $37,000 — effectively making their super contributions tax-free. The government co-contribution provides a matching contribution for eligible earners who make personal after-tax contributions, with the benefit phasing out as income rises.

Timing Your Contributions

Contributions must be counted in the right financial year — typically when received by your fund, not when paid. Contributions made close to 30 June need careful attention. For those using the carry-forward rule or making large bring-forward contributions, your total super balance is assessed as at 30 June in the prior year, so actions affecting that balance can affect eligibility the following year.

The Big Picture: Layering the Strategies

No single contribution strategy suits everyone. The most effective approach for most people involves layering: employer SG as the base, salary sacrifice to fully utilise the concessional cap, and personal or non-concessional contributions in years when additional cash is available. Reviewing your strategy annually — particularly around June — and adjusting for changes in income and family circumstances is a habit that consistently pays dividends.
