Understanding your marginal tax rate is essential for decisions about overtime, salary sacrifice, investment income, and side hustles. This guide covers every 2025-26 Australian tax bracket — and explains why your real tax bill is lower than most people think.

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.

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.
