Worked example
Measure the cash reduction and the benefit separately
A $5,000 pre-tax arrangement does not simply make you $5,000 better off. Model the salary before and after the supported sacrifice, compare the reduction in take-home pay, and then compare that cash cost with the amount directed to the benefit or super. Contribution caps, fringe benefits, employer rules and reportable amounts can change the real outcome.
Check before relying on it
- Get the arrangement in place before earning the sacrificed salary.
- Ask whether fees, fringe benefits tax or reportable amounts apply.
- Check contribution caps before sacrificing extra super.
- Compare the change in bank-account pay with the benefit received.
