Salary sacrifice into super: what to compare
Salary sacrifice can redirect pre-tax salary into super, but the useful comparison is the change in take-home pay, the amount arriving in the fund and the restrictions that apply to super money.

Follow the money through the comparison
A salary-sacrifice arrangement reduces the cash salary paid to you and directs the agreed amount to super. The calculator comparison should show the reduction in taxable income, the estimated reduction in personal income tax and the contribution tax applied inside super where relevant.
The amount contributed is not the same as the reduction in take-home pay because the personal tax saving can offset part of the cash reduction. The net benefit depends on the person's marginal tax position and the taxes applying to the super contribution.
Check caps and existing contributions
Employer super and other concessional contributions generally count towards the concessional contributions cap. A salary-sacrifice decision should therefore start with an estimate of contributions already expected for the year. Carry-forward rules and additional tax for higher-income earners can change the result and require personal advice.
Do not use a calculator default as proof that a contribution is allowed. Confirm current caps and the individual's contribution history through official records or a qualified adviser.
Balance tax efficiency with access
Super is intended for retirement and is generally preserved until a condition of release is met. Money directed to super is therefore not equivalent to cash available for a deposit, emergency fund or near-term expense. A strategy can be tax-efficient and still be unsuitable if it leaves the household without accessible savings.
- Confirm the employer's written salary-sacrifice process.
- Check the current contribution cap and year-to-date contributions.
- Allow for contribution tax and fund fees.
- Keep enough accessible cash for short-term obligations.
Review the arrangement regularly
Recheck the amount after a pay rise, change of employer, bonus, extended leave or change in government settings. Preserve payslips, contribution records and the written agreement so the calculation can be reconciled with what the employer and fund actually processed.
