**Threshold:** $190,000

For the 2025–26 financial year, the top marginal rate of 45% applies to taxable income exceeding **$190,000** for Australian resident individuals. That is, every dollar of taxable income above $190,000 is taxed at 45 cents in the dollar (Medicare levy is additional and separate).

**Controlling authority:** The resident individual income tax rates and thresholds are set by the *Income Tax Rates Act 1986* (Cth), as amended by the Australian Parliament (most recently restructured by the "Stage 3" amendments in the *Treasury Laws Amendment (Cost of Living Tax Cuts) Act 2024*). The Australian Taxation Office administers the rates but does not set them.
