Tax Bracket

A tax bracket is a slice of income with its own tax rate — Australia has five for residents in 2025-26. Your salary is taxed slice by slice, so moving up a bracket never re-taxes the income you already earned.

What it is

A tax bracket is a range of income taxed at one specified rate. Australia's resident system stacks five of them for 2025-26: nothing on the first $18,200, 16% on income from $18,201 to $45,000, 30% from $45,001 to $135,000, 37% from $135,001 to $190,000, and 45% above $190,000. Your payslip's PAYG withholding is payroll spreading those slices across your pay periods all year.

The single most important property of brackets is that they apply to slices, not to your whole income. Crossing into the 37% bracket at $135,001 changes the tax on exactly the dollars above that line and nothing below it. The myth that a raise can push all your income into a higher rate has cost Australians real money in declined pay rises.

Bracket thresholds are set in legislation and fixed in dollar terms. They are not automatically indexed to inflation, which is how bracket creep quietly raises your average tax over time even when rates stay put.

Key takeaways

Australia has five resident brackets for 2025-26: nil, 16%, 30%, 37% and 45%, rising with income.
Each bracket taxes only the income inside its range — the slices below keep their lower rates.
Crossing into a higher bracket raises tax on the extra dollars only, never on your whole salary.
The revised stage 3 cuts from 1 July 2024 reshaped the brackets to 16% and 30% headline rates.
Bracket thresholds are not indexed to inflation, so real wages drift into higher slices over time.

How it works

Every dollar of taxable income is sorted, from the bottom up, into the bracket ranges. Dollars one to 18,200 pay nil. Dollar 18,201 onward pays 16 cents until the total reaches $45,000, then the next dollars pay 30 cents until $135,000, then 37 cents to $190,000, and 45 cents above that. Total income tax is the sum of what each slice owes, and the 2% Medicare levy is added on taxable income afterwards.

Worked end to end for $90,000 of taxable income: the first $18,200 owes nothing, the next $26,800 owes 16% — $4,288 — and the remaining $45,000 owes 30% — $13,500. Total tax is $17,788, Medicare adds $1,800, and the combined bill is $19,588. The marginal rate is 30%, the effective rate including Medicare is about 21.8%, and both numbers are simply different views of the same stack.

On the payslip, none of this is visible. Payroll uses ATO withholding tables that encode the same bracket maths, so fortnightly PAYG is just the annual slice-sum divided by 26. The payg withholding tool shows the translation from bracket table to payslip line.

Why it matters

Brackets decide what your raise, bonus and second job are worth — and they are the most mythologised numbers in Australian personal finance. Half of all bad salary decisions trace back to one error: believing the top rate applies to the whole income once you cross a threshold.

I know a Brent (yes, that Brent) who asked his manager to cap his salary at $44,900 because 'the next bracket eats the difference'. At $44,900 his marginal rate was 16%; crossing $45,000 would have moved only the excess into 30%. He declined thousands of dollars a year to avoid a rate that applied to, at most, a few hundred of them. The bracket did not eat anything. Brent was simply misinformed with confidence.

The highest-leverage thing most Australians can do is memorise the five bracket boundaries and current rates. They take two minutes to learn, they change rarely, and they quietly underpin every pay negotiation you will ever have.

Real-world examples

The full slice breakdown on a $90,000 taxable income, 2025-26

Slice one: $18,200 taxed at nil — $0. Slice two: $26,800 at 16% — $4,288. Slice three: the remaining $45,000 at 30% — $13,500. Income tax totals $17,788, the 2% Medicare levy adds $1,800, and the year owes $19,588. Fortnightly that is roughly $753 withheld from a $3,462 gross, leaving about $2,709 in take-home pay. Three slices, two rates, zero mystery.

A $2,000 raise crossing the $45,000 threshold

A worker moving from $44,000 to $46,000 first pays 16% on the $1,000 up to $45,000 — $160 — then 30% on the $1,000 above it — $300. Total extra tax is $460, plus $40 of Medicare levy, so $1,500 of the $2,000 survives. Without bracket-slicing, Brent's version of this story has the full $46,000 re-taxed at 30% and the raise being a trap. Arithmetic disagrees.

Where each bracket boundary sits and what it costs

The dollar you earn at $18,201 starts costing 16 cents. The dollar at $45,001 starts costing 30 cents — a 14-cent jump, worth $14 per $100 of marginal income. At $135,001 the step is 30 to 37 cents, and at $190,001 it is 37 to 45. Each boundary is just a price change on the next dollar, nothing more dramatic than that. The wage checker and pay rise tools price offers slice by slice rather than against a single rate, which is the whole reason the arithmetic in their results never matches the barbecue version.

Common mistakes

Mistake: Believing moving up a bracket re-taxes your whole income at the new rate.

Why it bites you: Only the dollars above the threshold pay the higher rate. Crossing $45,000 with a $1,000 raise costs $300 extra tax, not 30% of your entire salary — a myth that has cost people real raises.

Mistake: Quoting last decade's brackets at today's negotiation.

Why it bites you: The 1 July 2024 stage 3 redesign replaced the old 19% and 32.5% steps with 16% and 30%. Negotiating off outdated rates misprices your own pay by hundreds of dollars a year.

Mistake: Forgetting the Medicare levy sits on top of the bracket rates.

Why it bites you: The levy is 2% of taxable income for most earners. On $90,000 that is $1,800 a year beyond the bracket math, roughly $69 a fortnight your budget did not plan for.

Mistake: Assuming thresholds rise with inflation automatically.

Why it bites you: They are fixed in legislation and only move when Parliament moves them. Wage growth silently drags you toward higher slices — bracket creep — even when your buying power stands still.

Ivy's take

I spent an evening reading the Income Tax Rates Act amendments through the stage 3 redesign so you don't have to, with coffee, at a table that wobbles. The brackets are not complicated. Five slices, five rates, lifetime relevance, and the entirety of dinner-party tax commentary fits on a napkin.

What is complicated is the folklore wrapped around them. Somewhere along the line Australia decided brackets work like airlocks: cross one and the vacuum takes everything. Brackets work like a toll road with different pricing per stretch — you only pay the new rate on the new stretch. Brent avoids toll roads by walking, then invoices you for his time. Memorise the five numbers, check which slice your next raise lands in, and let the airlock theory die with dignity.

Related jargon, defined

Taxable income: Assessable income minus deductions — the figure the brackets are applied to.
Marginal tax rate: The rate of the highest bracket your income reaches; what your next dollar is taxed at.
Effective tax rate: Your total tax as a percentage of total income — always below your top bracket's rate.
Tax-free threshold: The first $18,200 of income, taxed at nil for Australian residents.
Bracket creep: Inflation pushing wages into higher brackets without any real gain, because thresholds are not indexed.
Progressive tax: A system where the rate rises with income, via brackets, instead of one flat rate.

Frequently asked questions

What are the Australian tax brackets for 2025-26?+

Residents pay nil up to $18,200, then 16% to $45,000, 30% to $135,000, 37% to $190,000 and 45% above that. The 2% Medicare levy applies on top for most earners.

If I get a raise into a higher bracket, is my whole salary taxed more?+

No, and this is the most expensive myth in personal finance. Only the dollars above the threshold pay the new rate, so a raise always increases your take-home pay.

When did the tax brackets last change in Australia?+

1 July 2024, when the revised stage 3 cuts replaced the 19% and 32.5% rates with 16% and 30% and lifted the top thresholds. Rate changes since have been proposals, not law.

Which tax bracket am I in on an $80,000 salary?+

The 30% bracket, because $80,000 sits between $45,001 and $135,000. Your top dollars face 30 cents of tax plus 2 cents of Medicare levy; your average rate is far lower.

Do tax brackets rise with inflation each year?+

No. Australian thresholds are fixed dollar amounts set by legislation, so they only move when Parliament acts. That gap between fixed thresholds and rising wages is bracket creep.
