This calculator applies the Australian Tax Office (ATO) marginal tax brackets for the selected financial year. Marginal tax means each “band” of income is taxed at its own rate, you do not pay the top rate on your whole income.
How Australian Marginal Tax Works
Australia uses a progressive (marginal) tax system. Your income is divided into bands (called “tax brackets”) and each band is taxed at its own rate. You do not pay the top rate on your whole income, only on the portion of income that falls into that bracket.
Worked example: $85,000 income, FY 2025-26
Marginal vs effective tax rate
The example above shows two different “rates”:
- Marginal rate (30%), the rate of the highest bracket your income reaches. It is what you would pay on your next dollar earned, useful for thinking about overtime, bonuses or salary sacrifice decisions.
- Effective rate (~21%), your total tax divided by your total income. Always lower than your marginal rate because of the tax-free threshold and progressively-increasing brackets.
Stage 3 tax cuts (from 1 July 2024)
The Stage 3 reform changed three things from FY 2024-25 onwards:
- The 19% bracket dropped to 16%
- The 32.5% and 37% bands were collapsed into a single 30% band covering $45,001 to $135,000
- The 37% bracket now starts at $135,001 instead of $120,001
Try switching the “Tax Year” selector above to FY 2023-24 and re-running the calculator to see what you would have paid before the cuts.
Why this matters for your home loan
Lenders calculate your borrowing capacity from your after-tax (net) income, not your gross. Understanding how much of your gross actually lands in your bank account is the first step in working out what you can afford. Once you know your net, use our Borrowing Power Calculator to see how much a lender would approve, or get in touch with David for a personalised assessment.
