The Australian Tax System: ATO Slabs & Reforms
In Australia, personal income tax is assessed and collected at the federal level by the Australian Taxation Office (ATO). Unlike the United States or Canada, there are no state or provincial income taxes in Australia—the tax rates are uniform whether you live in Sydney (NSW), Melbourne (VIC), Brisbane (QLD), Perth (WA), or Adelaide (SA).
Following the landmark revised Stage 3 Tax Cuts, millions of Australian workers enjoy reduced income tax brackets and higher take-home pay.

2024–2025 & 2025–2026 ATO Resident Tax Rates (Stage 3 Revised Slabs)
Australian tax residents benefit from a $18,200 Tax-Free Threshold. Taxable income above this threshold is taxed according to the following progressive rates:
| Taxable Income Tier (AUD) | Marginal Tax Rate | Tax on This Tier |
|---|---|---|
| $0 to $18,200 | 0.0% (Tax-Free) | $0 |
| $18,201 to $45,000 | 16.0% | $0 + 16c for each $1 over $18,200 |
| $45,001 to $135,000 | 30.0% | $4,288 + 30c for each $1 over $45,000 |
| $135,001 to $190,000 | 37.0% | $31,288 + 37c for each $1 over $135,000 |
| Over $190,000 | 45.0% | $51,638 + 45c for each $1 over $190,000 |
Key Takeaway from Stage 3 Cuts: The lowest marginal rate was reduced from 19% to 16%, the 30% rate threshold extends up to $135,000, and the top 45% threshold was lifted to $190,000.
The 2.0% Medicare Levy & Surcharge
1. Standard Medicare Levy (2.0%):
Most Australian residents pay a mandatory 2.0% Medicare Levy on their taxable income to fund Australia's universal healthcare system (Medicare). Low-income earners receive complete exemption or phase-in reductions under the Medicare levy low-income threshold.
2. Medicare Levy Surcharge (MLS) (1.0% to 1.5%):
If you earn over $97,000 as a single individual (or $194,000 for families) and do not hold an appropriate level of private hospital insurance, you are hit with an additional 1.0% to 1.5% Medicare Levy Surcharge.
- Pro Tip: Taking out basic private hospital cover is often cheaper than paying the surcharge!
Superannuation Guarantee (11.5% in 2024/25 -> 12.0% in 2025/26)
In Australia, employers must pay mandatory retirement contributions known as the Superannuation Guarantee (Super) on top of your base salary into your nominated super fund:
- 2024–2025 Rate: 11.5% of Ordinary Time Earnings (OTE)
- 2025–2026 Rate: 12.0% of Ordinary Time Earnings (OTE)
Superannuation contributions are taxed at a concessional rate of only 15% inside the fund, providing a massive wealth accumulation vehicle compared to marginal income tax rates up to 45%.
