Can You Salary Sacrifice a Bonus in Australia? (2025-26)

General information only. This is not tax or financial advice.

If you are about to receive a bonus, the practical question is usually not just “how much tax will they withhold?” but “can I salary sacrifice this bonus before it is paid?”

Often, the answer is yes, but only if the arrangement is set up early enough. If the bonus has already been earned, accrued, or you are already entitled to it, it is usually too late to turn that amount into an effective salary sacrifice contribution.

The rule that matters

The ATO’s position is that an effective salary sacrifice arrangement must be made for future earnings. It cannot cover salary, wages, bonuses, or commissions that you have already earned or become entitled to.

That means timing matters more than intent:

if the agreement is in place before you become entitled to the bonus, salary sacrifice may work
if you try to do it after the bonus is locked in, it is generally not an effective salary sacrifice arrangement

When a bonus can usually be salary sacrificed

You are in the safer zone when:

the employer has not yet paid the bonus
you are not yet presently entitled to that bonus under your contract or pay decision
the salary sacrifice arrangement is agreed and documented before the bonus becomes payable
the sacrificed amount goes to a complying super fund

In that situation, the sacrificed amount is generally treated as an employer super contribution, not ordinary assessable salary.

When it is usually too late

It is commonly too late if:

the bonus has already been declared as payable to you
the bonus has already been earned or accrued under the arrangement
the amount is already part of salary or wages you can access
you are trying to redirect a bonus after payroll has effectively been set

If the arrangement is not effective, the amount is generally treated as normal salary or wages and remains subject to PAYG withholding.

Why people use this strategy

The attraction is simple:

cash paid to you directly is taxed through PAYG withholding and then reconciled in your annual return
salary sacrificed super contributions are generally taxed in the fund at 15%

That can be attractive when your marginal tax rate is much higher than 15%. But it is not automatically a win.

What can still make it a bad move

Do not stop at the tax rate headline.

You still need to check:

whether the sacrificed amount pushes you over your concessional contributions cap
whether your combined income and concessional contributions expose you to Division 293 tax
whether you actually need the cash now rather than locking it in super
whether the bonus is already too close to payment to change payroll properly

The decision is partly tax, partly timing, and partly cashflow.

Practical decision path

Use this order:

If the bonus has not been paid yet, ask whether you are already entitled to it under your contract or payroll process.
If the answer is “not yet”, test the cash outcome in the Salary Sacrifice Calculator.
Compare that with the direct-cash outcome in the Bonus Tax Calculator.
If you still need a broader salary view, check the Pay Calculator.

The practical takeaway

If your question is “can I salary sacrifice a bonus?”, the real answer is:

before entitlement: maybe, if the arrangement is set up properly
after entitlement: usually no, not as an effective salary sacrifice arrangement

That is why the decision should be made before the bonus pay run, not after the payslip surprises you.
