Concessional Contributions Cap Calculator
See how much of the $30,000 concessional cap you've used and how much tax you save through salary sacrifice.
Understanding the Concessional Contributions Cap
Concessional contributions are pre-tax super contributions — they are taxed at just 15% inside your fund (instead of your marginal income tax rate). The cap limits how much can receive this concessional tax treatment each year.
What Counts Towards the Cap
- Employer SG contributions — 11.5% of ordinary time earnings (2024–25)
- Salary sacrifice contributions — additional pre-tax amounts you arrange with your employer
- Personal deductible contributions — contributions where you lodge a Notice of Intent to Claim a Deduction (for self-employed or those wanting to top up)
The Tax Saving Calculation
The tax saving from salary sacrifice is the difference between your marginal rate and the 15% contributions tax. For example, at the 37% marginal rate, sacrificing $10,000 saves $2,200 in tax. The higher your marginal rate, the greater the benefit.
Carry-Forward Rules
If your total super balance was below $500,000 at 30 June of the prior year, unused cap space from the past five years can be carried forward and used in a single year. This can allow contributions well above $30,000. Check the ATO's myGov portal for your available carry-forward amount.
Division 293 Tax
If your income plus concessional contributions exceeds $250,000, an extra 15% Division 293 tax applies to the concessional contributions (or the amount above $250,000, whichever is less). This reduces (but does not eliminate) the tax benefit of salary sacrifice at high incomes.
