Salary Sacrifice Mortgage: How the Pay Floor Affects Your Borrowing Power

Salary sacrifice mortgage and the pay floor

A salary sacrifice mortgage arrangement lets you use pre-tax salary to pay your home loan, reducing your taxable income. But how does this interact with Australia's minimum wage laws? This guide explains the legal pay floor, award rates, and average earnings so you can understand your borrowing power.

The legal minimum wage

The Fair Work Commission sets the national minimum wage. From 1 July 2026, the adult rate is $26.44 per hour or $1,004.90 per week for a 38-hour ordinary week. Casual employees receive a 25% loading, making the casual minimum $33.05 per hour. These are before tax and before super. Employers must also pay super guarantee of 12% on top of ordinary time earnings—that's an extra $120.59 per week for a full-time minimum wage worker.

Not every worker receives the full adult rate. Juniors, apprentices, trainees, and supported wage employees can be paid less. For award-free juniors, rates range from $9.73 per hour (under 16) to $25.84 per hour (age 20). Introductory award rates for the first six months are $25.74 per hour or $978.10 per week. A modern award or enterprise agreement can require a higher rate than the national minimum.

Separating the legal minimum from other benchmarks

The legal floor is not the same as a survey average, an award rate, or a negotiated salary. The Australian Bureau of Statistics (ABS) reported in May 2026 that full-time adult ordinary-time earnings averaged $2,083.70 per week, and all employees averaged $1,579.20 per week in total earnings. These figures include overtime, bonuses, and salary sacrifice arrangements. They are much higher than the minimum wage.

Award rates vary by industry and classification. The Fair Work Ombudsman explains and enforces awards, but the Fair Work Commission sets the national minimum. If you are covered by an award, your minimum wage is at least the national minimum, but often higher. Enterprise agreements can also set higher rates.

How salary sacrifice affects your mortgage borrowing

When you salary sacrifice part of your wage to your mortgage, your taxable income drops. However, lenders usually assess your gross income (before sacrifice) when deciding how much you can borrow. So earning the minimum wage of $1,004.90 per week still gives you a borrowing base. But your actual take-home pay after sacrifice is lower, which may affect your living expenses and serviceability calculations.

Super guarantee is paid on your ordinary time earnings, not on the sacrificed amount. That means your super contributions remain based on your full wage, even if you sacrifice some to your mortgage. This is important for long-term retirement savings.

Award and agreement rates

If you are under a modern award, your minimum hourly rate may be above $26.44. For example, many awards have higher classifications. You cannot be paid below the award rate, even with a salary sacrifice arrangement. The sacrifice comes out of your gross pay, but your base rate must still meet the award minimum. Enterprise agreements may also have specific rules about salary sacrifice.
