This guide details statutory contribution caps, tax arbitrage rates, salary sacrifice setup steps, and real-world worked examples.
1. Tax Arbitrage: 15% Super Tax vs Marginal Tax Rates

In contrast, pre-tax salary sacrifice super contributions enter your superannuation fund as concessional contributions and are taxed at a flat statutory rate of 15%.
2. Concessional Contribution Caps & Carry-Forward Rules
For the 2026–2027 tax year, the general annual concessional contribution cap is $30,000.
