Quick Answer: Salary Sacrifice Super

Salary sacrificing means asking your employer to redirect part of your pre-tax salary into super instead of paying it to you as cash. So, that amount gets taxed at 15% inside super, rather than your normal marginal tax rate, which is often much higher. The concessional cap for 2025-26 is $30,000 a year, including your employer’s compulsory contributions. It rises to $32,500 for 2026-27. Two real changes matter right now. The Super Guarantee rate reached its final legislated 12% on 1 July 2025. Payday Super started 1 July 2026, meaning employers must pay super closer to each payday instead of once a quarter.

How Salary Sacrifice Super Actually Saves You Tax

Normal salary gets taxed at your marginal rate. So, if you’re in a higher tax bracket, a meaningful chunk of every extra dollar goes to tax before you even see it.
Salary sacrificed super gets taxed at just 15% instead. That’s a real saving for most people earning above the lowest tax brackets.
A simple example shows the gap clearly. So, someone on a 32.5% tax rate who sacrifices $10,000 saves roughly $1,750 in tax. That’s compared to taking the same $10,000 as normal salary.
The money isn’t accessible until retirement, though. That’s the trade-off. So, only sacrifice what you’re comfortable locking away until you meet a condition of release.

The Concessional Cap: What You Can Actually Contribute

The cap for 2025-26 sits at $30,000 a year. This includes everything: your employer’s compulsory contributions plus anything you salary sacrifice on top.
It rises to $32,500 for 2026-27. So, the cap gets indexed periodically in line with wage growth, not adjusted every single year.
Your compulsory employer contributions count toward this cap first. So, work out your remaining room before deciding how much to sacrifice.
Going over the cap has a real cost. Excess concessional contributions get taxed at your marginal rate, plus an extra charge, so it’s worth tracking your total contributions through the year.

The Super Guarantee Rate Has Hit Its Final Level

The Super Guarantee rate reached 12% on 1 July 2025. This was the last step of a decade-long, gradual increase that started back in 2013.
There’s no further scheduled increase after this. So, 12% is the rate you can plan around going forward, at least under current legislation.
If you’re on a fixed total-package contract, this affects your cash salary slightly. So, the higher compulsory rate comes out of the same total package, leaving a bit less as take-home cash.
On a $120,000 package, that shift works out to roughly $480 a year. So, it’s a small but real number worth knowing before you decide how much extra to sacrifice.

Payday Super: What Actually Changed From July 2026

Employers used to pay super quarterly, by the 28th day after each quarter. That meant a real lag. Your super could sit unpaid for up to 4 months after you earned it.
From 1 July 2026, employers must pay super on or near each payday instead. So, the long delay is largely gone.
This makes your contributions visible much sooner. Instead of waiting months, you can generally see contributions land within days of each pay run.
For salary sacrifice specifically, this means less lag between when you sacrifice and when it actually reaches your fund. So, your sacrificed amount starts earning investment returns sooner than it used to.
