Super contribution caps limit how much you can put into super each financial year while receiving favourable tax treatment. Going over the cap triggers additional tax. Understanding the caps — and how to maximise them — is essential for anyone serious about building their retirement savings.
Contribution caps for 2025–26
| Cap type | Limit (2025–26) | Tax rate on contributions |
|---|---|---|
| Concessional (before-tax) | $30,000 | 15% (or 30% if income + contributions > $250K) |
| Non-concessional (after-tax) | $120,000 | Nil (already taxed) |
| Non-concessional bring-forward (under 75) | $360,000 over 3 years | Nil |
What counts as concessional contributions?
Concessional contributions include:
- Employer SG contributions (12% of ordinary time earnings)
- Salary sacrifice contributions
- Personal deductible contributions (claimed as a tax deduction)
All of these are taxed at 15% inside super (or 30% if Division 293 applies). The $30,000 cap includes all concessional contributions — so if your employer pays $12,000 in SG, you can salary sacrifice or claim a deduction for up to $18,000 more.
Carry-forward unused concessional cap
If you have a total super balance below $500,000 at 30 June of the previous financial year, you can carry forward unused concessional cap space from the past 5 financial years. This allows you to make large catch-up contributions in years when you can afford it.
Non-concessional contributions
Non-concessional (after-tax) contributions are capped at $120,000 per year. These come from money you've already paid income tax on, so they're not taxed again inside super. If you're under 75, you can bring forward up to 3 years' worth ($360,000) in a single year — useful for contributing a lump sum from a property sale or inheritance.
What happens if you exceed the caps?
- Excess concessional contributions: The excess is added to your assessable income and taxed at your marginal rate (with a 15% tax offset for tax already paid by the fund). You can choose to have up to 85% of the excess released from your fund to pay the tax.
- Excess non-concessional contributions: You can elect to withdraw the excess plus associated earnings. If you don't, the excess is taxed at 47%.
Strategies for maximising contributions
- Use carry-forward to make catch-up contributions in high-income years
- Self-employed? Claim a personal deduction for contributions
- Use salary sacrifice for automatic, regular concessional contributions — see our salary sacrifice guide
- Consider spouse contribution splitting to equalise balances and maximise tax benefits for both partners
