When I was building the Australian Income Tax calculator, I had to completely rewrite our tax bracket algorithms to account for the major legislative shift: the revised Stage 3 tax cuts. The changes restructured middle-income tax brackets and lowered marginal rates for millions of taxpayers, meaning my old calculation logic was completely outdated.
Understanding how these revised brackets, the 2.0% Medicare Levy, and the Medicare Levy Surcharge (MLS) combine to impact your take-home pay slip can be challenging. I designed our updated tax calculator to make this progressive math simple, letting you toggle between financial years and see exactly how much extra cash you pocket under the new legislation.

1. Revised Stage 3 Tax Brackets (2026 Tax Year)
Under the Australian progressive income tax system, tax is charged on portions of income falling within specific thresholds:
+-------------------------------------------------------------------+
| AUSTRALIAN STAGE 3 TAX RATE BRACKETS |
+-------------------------------------------------------------------+
| $0 - $18,200 : 0% Tax (Tax-Free Threshold) |
| $18,201 - $45,000 : 16% on amount over $18,200 |
| $45,001 - $135,000 : $4,288 + 30% on amount over $45,000 |
| $135,001 - $190,000 : $31,288 + 37% on amount over $135,000 |
| $190,001+ : $51,638 + 45% on amount over $190,000 |
+-------------------------------------------------------------------+
Key reforms under the revised Stage 3 package:
- Reduced the lowest marginal rate from 19% to 16% (saving lower-income earners up to $804/yr).
- Reduced the 32.5% marginal rate to 30% and expanded the upper threshold to $135,000.
- Retained the 37% rate for income between $135,000 and $190,000.
- Retained the top 45% rate starting at $190,000.
2. Medicare Levy & Medicare Levy Surcharge (MLS)
In addition to personal income tax, most Australian tax residents pay healthcare levies:
1. Standard Medicare Levy (2.0%)
A flat 2.0% levy assessed on your total taxable income to help fund Medicare. Low-income earners pay reduced or zero Medicare levy if earning below $32,500 (single) or $55,000 (family).
2. Medicare Levy Surcharge (MLS)
Higher earners who do not maintain eligible private hospital health insurance pay an additional 1.0% to 1.5% MLS:
| Single Income Threshold | Family Income Threshold | MLS Rate Added |
|---|---|---|
| $0 – $97,000 | $0 – $194,000 | 0.0% (Exempt) |
| $97,001 – $108,000 | $194,001 – $216,000 | 1.0% |
| $108,001 – $144,000 | $216,001 – $288,000 | 1.25% |
| $144,001+ | $288,001+ | 1.5% |

Step-by-Step Worked Calculation: $110,000 Salary
Let's calculate the exact ATO tax bill for an Australian resident earning $110,000 per year holding private hospital cover:
- Tax-Free Bracket ($0 – $18,200): $0 tax.
- First Bracket ($18,201 – $45,000): ($45,000 - $18,200) × 16% = $4,288.
- Second Bracket ($45,001 – $110,000): ($110,000 - $45,000) × 30% = $19,500.
- Gross Income Tax Total: $4,288 + $19,500 = $23,788.
- Medicare Levy (2.0%): 2% × $110,000 = $2,200.
- Total ATO Tax Withheld: $23,788 + $2,200 = $25,988.
- Net Take-Home Pay: $110,000 - $25,988 = $84,012 / year ($3,231 fortnightly).
Frequently Asked Questions (FAQ)
What is the Tax-Free Threshold in Australia?
The first $18,200 of income earned by Australian tax residents each financial year is tax-free (0% rate).
How does LITO (Low Income Tax Offset) work?
LITO provides a tax offset of up to $700 for taxpayers earning $37,500 or less, phasing out completely at $66,667.
Why do I pay Medicare Levy Surcharge if I earn over $97,000?
The federal government uses MLS to incentivize higher earners to buy private health insurance, taking pressure off the public Medicare hospital system.
Are superannuation employer contributions taxed under these brackets?
No. Employer Super Guarantee (SG) contributions are taxed inside your super fund at the concessional rate of 15%, not under personal income tax brackets.
How often are Australian income taxes paid?
Employers withhold tax from each paycheck via the PAYG (Pay-As-You-Go) withholding system. Any over- or under-payment is reconciled when lodging your annual ATO tax return in July.
What is the top marginal tax rate in Australia?
The top marginal tax rate is 45% on income over $190,000, plus the 2.0% Medicare Levy (effective top marginal rate of 47.0%).
What is the Low Income Tax Offset (LITO) and how much is it worth?
The Low Income Tax Offset provides up to $700 tax reduction for earners below $37,500. It phases out progressively: reduced by $0.05 for every dollar between $37,500–$45,000, and by $0.015 for every dollar between $45,001–$66,667, reaching zero at $66,667.
Does Australia have a Capital Gains Tax (CGT) discount?
Yes. Australian tax residents who hold an asset for more than 12 months receive a 50% CGT discount on the net capital gain, meaning only half the gain is added to taxable income and taxed at marginal rates.
Real-World Case Studies: Stage 3 Tax Cut Winners
Case Study 1: Graduate Nurse, $72,000 Salary (Brisbane)
Pre-Stage 3 tax (old system):
- Income tax: $16,342 + Medicare Levy $1,440 = $17,782 total
Post-Stage 3 tax (2026 system):
- Income tax: $4,288 + (72,000 − 45,000) × 30% = $4,288 + $8,100 = $12,388 + Medicare $1,440 = $13,828 total
Annual saving: $3,954 — enough to cover 2 months of rent or a return international flight.
Case Study 2: Senior Engineer, $150,000 Salary (Sydney)
| Component | Old System | Stage 3 (2026) | Saving |
|---|---|---|---|
| Income Tax | $43,567 | $37,838 | +$5,729 |
| Medicare Levy | $3,000 | $3,000 | — |
| Total ATO Tax | $46,567 | $40,838 | $5,729 |
| Net Take-Home | $103,433 | $109,162 | +$5,729/yr |
Case Study 3: Small Business Owner, $195,000 Net Profit (Melbourne)
At $195,000 income, the taxpayer enters the 45% bracket on $5,000 of income (the portion above $190,000):
- Tax on $190,000: $51,638
- Tax on remaining $5,000 at 45%: $2,250
- Total income tax: $53,888
- Medicare Levy (2%): $3,900
- Total ATO liability: $57,788
- Effective rate: 29.6% — not 47% as many business owners fear
Key insight: The marginal rate only applies to the dollars above the threshold. A $195,000 earner does NOT pay 47% on their full income.
