Australia FAQs
What are the 2025-26 Australian tax brackets?
Five brackets for residents: A$0-$18,200 at 0% (tax-free), A$18,201-$45,000 at 16%, A$45,001-$135,000 at 30%, A$135,001-$190,000 at 37%, and A$190,001+ at 45%.
What changed with Stage 3 tax cuts?
From 1 July 2024, the 19% rate dropped to 16%, and the 32.5% rate dropped to 30%. The $120,000 threshold was raised to $135,000, and the $180,000 threshold to $190,000. Most taxpayers save A$800-$4,500 annually.
What is my effective tax rate on A$100,000?
On A$100,000: income tax is approximately A$20,788 plus A$2,000 Medicare levy. Effective rate is about 22.8%. Your marginal rate is 30% (every extra dollar above $45,000 is taxed at 30c).
What is the difference between marginal and effective rate?
Marginal rate is the tax on your next dollar of income (the bracket you fall into). Effective rate is total tax divided by total income. On A$80,000, marginal rate is 30% but effective rate is only about 20.5%.
Is the Medicare levy included in the brackets?
No. The 2% Medicare levy is calculated separately on top of income tax. On A$80,000: income tax ~A$14,788 + Medicare levy A$1,600 = total A$16,388. Low-income earners may qualify for a reduction.
Do non-residents pay the same rates?
No. Non-residents have no tax-free threshold and pay 32.5% from the first dollar up to A$135,000, then 37% and 45%. Non-residents also do not pay the Medicare levy but cannot access Medicare services.
What is the Medicare Levy Surcharge?
An additional 1-1.5% surcharge on top of the 2% levy for higher earners (singles above A$93,000, families above A$186,000) who do not hold private hospital insurance. Taking out basic hospital cover avoids this surcharge.
