Marginal Rate vs. Effective Rate — What Is the Difference?
Marginal tax rate is the rate that applies to your last dollar of income. If you earn $80,000, your marginal income tax rate is 30% — but that only applies to income above $45,000.
Effective (average) tax rate is your total tax divided by total income. At $80,000:
- Income tax: $14,788
- Medicare levy: $1,600
- Total: $16,388
- Effective rate: $16,388 ÷ $80,000 = 20.5%
Even though you are in the 30% tax bracket, you only pay 20.5% of your income in tax — because the lower brackets still apply to your lower income.
Marginal Rate at Common Salary Levels (2025-26)
| Annual salary | Marginal income tax rate | Marginal rate incl. Medicare | Effective rate (all-in) |
|---|---|---|---|
| $30,000 | 16% | 18% | ~5% |
| $50,000 | 30% | 32% | ~13% |
| $70,000 | 30% | 32% | ~18.8% |
| $80,000 | 30% | 32% | ~20.5% |
| $100,000 | 30% | 32% | ~23.8% |
| $120,000 | 30% | 32% | ~26.3% |
| $150,000 | 37% | 39% | ~26.6% |
| $200,000 | 45% | 47% | ~33.8% |
Why Your Marginal Rate Matters
Your marginal rate tells you the real cost of earning extra money and the real value of deductions:
- Overtime: At $80,000, earning $1 extra from overtime keeps only 68 cents (32% marginal rate).
- Salary sacrifice: Putting $5,000 into super saves you 30% income tax minus 15% contributions tax = 15% net (at the 30% bracket).
- Investment income: A $10,000 dividend is taxed at your marginal rate. At $100,000, you keep $6,800 after tax.
- Deductions: A $1,000 work deduction saves $300 in tax at the 30% bracket — $370 at 37%.
How the Low Income Tax Offset Affects Your Marginal Rate
The Low Income Tax Offset (LITO) of up to $700 phases out between $37,500 and $66,667. This creates an effective higher marginal rate in two phase-out zones:
- $37,500 – $45,000: 16% rate + 5% LITO phase-out = 21% effective marginal rate
- $45,001 – $66,667: 30% rate + 1.5% LITO phase-out = 31.5% effective marginal rate
Above $66,667, LITO is zero and your marginal rate is simply the bracket rate plus Medicare. Use our pay calculator to see your exact take-home including LITO.
Frequently Asked Questions
What is my marginal tax rate in Australia for 2025-26?
For most Australians: 0% (under $18,200), 16% ($18,201–$45,000), 30% ($45,001–$135,000), 37% ($135,001–$190,000), or 45% (over $190,000). Add 2% Medicare levy.
What is the difference between marginal and effective tax rate?
Marginal rate is the tax on your next dollar. Effective rate is total tax ÷ total income. At $100,000 the marginal rate is 32% but the effective rate is only about 23.8% — because lower income is taxed at lower rates.
Did the Stage 3 tax cuts lower marginal rates?
Yes. From 1 July 2024: the 19% bracket became 16%, the 32.5% bracket became 30%, and the 37% threshold rose from $120,000 to $135,000. Everyone earning over $18,200 benefits.
What bracket is $80,000 in Australia?
At $80,000, your marginal income tax rate is 30% (the $45,001–$135,000 bracket). Including Medicare levy, every extra dollar earns you 68 cents take-home.
