Tax brackets for 2025–2026

Australia uses 5 progressive tax brackets for residents in 2025–2026: the first $18,200 of taxable income is tax-free, and income above that is taxed at marginal rates of 16%, 30%, 37%, 45%. These rates apply to the financial year from 1 July 2025 to 30 June 2026, and a 2% Medicare levy applies on top for most residents.

Source: ATO — Tax rates for Australian residents. Stage 3 cuts (in force from 1 July 2024) reduced the second bracket to 16%. These brackets apply to Australian residents claiming the tax-free threshold — non-residents, working-holiday makers, and minors use separate ATO scales. Sole traders pay these same brackets on business profit — the ABN tax calculator applies them to contract income. For a year-by-year reference table, see tax rates 2025–2026.

Tax on $100,000 in 2025–2026

On a $100,000 taxable income, WageCalculator's figures show $20,788 in income tax plus $2,000 Medicare levy — a total of $22,788 before LITO, HECS, or MLS. That is an effective rate of about 22.8%, well below the 30% marginal rate that bracket sits in.

Legislated cuts from 1 July 2026

The Australian Government has legislated further cuts to the rate on the second bracket ($18,200$45,000), stepping down from 1 July 2026 and again from 1 July 2027. See the Budget cost-of-living factsheet for the announced path — this guide will switch to the new rates when the 2026–27 year starts.

Income tax only. Medicare levy, HECS/HELP, offsets, salary sacrifice, and other deductions are handled in the full calculator.

This interactive example shows income tax only. For full take-home pay including Medicare levy, HECS/HELP, super, and deductions, use the pay calculator.

Worked example: $80k

On an $80,000 taxable income, you pay $0 on the first $18,200, plus $4,288 on $18,201 – $45,000, plus $10,500 on $45,001$80,000. Total income tax is $14,788 before offsets and before the Medicare levy.

How income tax is calculated

Income tax is calculated on your taxable income — assessable income (salary, investment income, etc.) minus allowable deductions — using the progressive marginal brackets above. Some lump sums follow their own rules instead of the brackets — redundancy payouts, for example, get a tax-free limit and concessional flat rates (see the redundancy tax guide). In practice your total tax bill stacks up to four components:

  1. 1

    Income tax

    Your taxable income is run through the marginal brackets — each slice of income is taxed at its bracket's rate.
  2. 2

    Medicare levy

    2% of taxable income for most residents, added on top of income tax.
  3. 3

    Medicare Levy Surcharge (if it applies)

    An additional 1%1.5% if your MLS income exceeds $101,000 and you don't hold eligible hospital cover.
  4. 4

    HECS/HELP repayments (if you have a loan)

    Compulsory repayments apply once your repayment income passes $67,000.

Tax offsets (like the LITO) then reduce the amount of tax you owe — but they don't reduce your taxable income. WageCalculator's pay calculator stacks all four components on your salary in one step.

If you are trying to work out what can still be claimed before lodgment, our tax return checklist is the practical companion to this guide.

Deductions vs offsets

A deduction lowers your taxable income. A tax offset lowers the tax payable after your tax has been calculated. This is why a $1,000 deduction and a $1,000 offset do not produce the same result.

Marginal vs effective tax rate

Your marginal tax rate is the rate charged on the last dollar of income you earn — it never applies to your whole salary. Your effective tax rate is your total tax divided by your total income, and it is always lower than your marginal rate.

Definition

Marginal tax rate

The tax rate that applies to the next dollar you earn — the rate of the highest bracket your income reaches. For 2025–2026 the marginal rates are nil, then 16%, 30%, 37%, 45%.

Definition

Effective tax rate

Total income tax divided by total taxable income. It blends every bracket your income passes through, so it sits well below your marginal rate.
Effective rate is income tax only (before Medicare levy, LITO, HECS, and MLS). The $80,000 row is highlighted — at this salary the marginal rate is 30% but the effective rate is about 18.5%.
Taxable incomeMarginal rateEffective rate
$50,00030%11.6%
$70,00030%16.8%
$80,00030%18.5%
$100,00030%20.8%
$120,00030%22.3%
$150,00037%24.6%
$250,00045%31.5%

This matters because a pay rise won't cause you to lose money. Even if a pay rise pushes you into a higher bracket, only the additional income is taxed at the higher rate — not your entire salary.

Tax offsets — Low Income Tax Offset (LITO)

The Low Income Tax Offset (LITO) reduces the tax you owe by up to $700 in 2025–2026: the full offset applies to taxable incomes up to $37,500, and it phases out completely at $66,667. It is applied automatically when you lodge — you don't need to claim it.

Offsets reduce tax payable, unlike deductions, which reduce your taxable income. Seniors and pensioners may also qualify for the separate Seniors and Pensioners Tax Offset (SAPTO), which stacks on top of LITO for eligible recipients.

Worked example: LITO on $35,000

On a $35,000 taxable income for 2025–2026, income tax before offsets is $2,688. The full $700 LITO cuts that to $1,988 — before the Medicare levy, which is assessed separately.
Income rangeLITO amount
$0 – $37,500Full $700 offset
$37,501 – $45,000Reduces by 5c per $1 above $37,500
$45,001 – $66,667Reduces by 1.5c per $1 above $45,000
$66,668+No offset
Source: ATO — Low income tax offset. LMITO ended on 30 June 2022, so only LITO applies for current years.

Medicare levy

The Medicare levy is 2% of taxable income for most Australian residents in 2025–2026, charged in addition to income tax. Singles earning up to $29,207 pay no levy, and the levy shades in until the full 2% applies above about $36,509.

Who pays less or nothing:

  • Singles earning up to $29,207 — generally no Medicare levy
  • Singles earning between $29,207 and about $36,509 — reduced levy (shade-in range)
  • Singles earning above about $36,509 — full 2% levy
  • Medicare Entitlement Statement holders — exempt

Source: ATO — Medicare levy. Family thresholds and special rules for SAPTO recipients also apply.

Medicare Levy Surcharge (MLS)

If your income for MLS purposes is above the threshold and you don't hold appropriate private hospital cover, you may pay an additional Medicare Levy Surcharge on top of the standard levy:

Income (single)Surcharge rate
$101,001 – $118,0001%
$118,001 – $158,0001.3%
$158,001+1.5%
Source: ATO — Medicare levy surcharge thresholds and rates. Family thresholds start at $202,000 and increase by $1,500 for each dependent child after the first.

MLS income is broader than salary alone and can include reportable fringe benefits, net investment losses, and reportable super contributions. For many people close to the threshold, taking out hospital cover costs less than paying the surcharge. Use our calculator to estimate whether you're in the surcharge zone, or read the dedicated Medicare Levy Surcharge guide for the deeper rules.

HECS/HELP repayments

If you have a HECS-HELP debt, compulsory repayments start once your repayment income exceeds $67,000 for 2025–2026.

From 1 July 2025, repayments use a marginal system rather than a single percentage on your whole income. For repayment income between $67,001 and $125,000, the repayment is 15c per dollar above $67,000. Between $125,001 and $179,285, it is $8,700 plus 17c per dollar above $125,000. At $179,286 or more, it is 10% of total repayment income.

Repayment income is broader than taxable income — it adds reportable fringe benefits, reportable super, net investment losses, and exempt foreign employment income. For indexation timing, voluntary repayment trade-offs, and full threshold tables, see the dedicated HECS/HELP repayment guide.

Reducing your tax bill

The most effective everyday ways to reduce tax are pre-tax super contributions, claiming all eligible deductions, salary packaging, and holding private hospital cover once your income passes the MLS threshold. Each lever works differently — and the higher your marginal rate, the more the pre-tax strategies are worth:

Salary sacrifice into super

Pre-tax super contributions are generally taxed at 15% inside the fund. For many employees, that is more favourable than taking the cash and paying tax at their marginal rate. The $30,000 concessional cap includes employer SG. See the salary sacrifice guide and super contributions guide, or try the super sacrifice calculator →

Claim all eligible deductions

Work-related expenses, vehicle costs, home office expenses, union fees, and self-education costs can all be deductible. Keep receipts throughout the year. Tax return checklist →

Novated lease (salary sacrifice for a car)

If your employer offers salary packaging, a novated lease can reduce after-tax car costs. The tax case is usually strongest for eligible EVs under $91,387, because those vehicles are exempt from FBT. Novated lease calculator →

Private health insurance (avoid MLS)

If you earn over $101,000, private hospital cover may cost less than the Medicare Levy Surcharge you would otherwise pay. Read the MLS guide →

What are the income tax brackets in Australia for 2025-26?

For 2025-26: $0 – $18,200 at 0%, $18,201 – $45,000 at 16%, $45,001 – $135,000 at 30%, $135,001 – $190,000 at 37%, $190,001+ at 45%. These are marginal rates, so you only pay each rate on the slice of income that falls within that bracket.

What is the difference between marginal and effective tax rate?

Your marginal rate is the tax rate on your last dollar of income. Your effective rate is your total tax divided by your total income. On an $80,000 salary, your marginal rate is 30% but your effective income-tax rate is about 18.5% before the Medicare levy.

What is the Low Income Tax Offset (LITO)?

The LITO is a non-refundable tax offset of up to $700 for lower-income earners. It reduces the tax you owe rather than your taxable income. For 2025-26, the full $700 applies up to $37,500 and phases out completely once taxable income reaches $66,667.

Do I have to pay the Medicare levy?

Most Australian residents pay a Medicare levy of 2% of taxable income. For 2025-26, singles on taxable income up to $29,207 generally pay no levy, and the levy phases in until the full 2% applies above about $36,509. Separate family and SAPTO thresholds also apply.

How do HECS-HELP repayments work?

From 1 July 2025, HECS-HELP uses a marginal repayment system. Repayments start once your repayment income exceeds $67,000. Between $67,001 and $125,000, the repayment is 15c per dollar above $67,000; between $125,001 and $179,285, it is $8,700 plus 17c per dollar above $125,000; and at $179,286 or more it is 10% of total repayment income.

How much tax do I pay on $70,000 in Australia?

On a taxable income of $70,000 for 2025-26, income tax is $11,788 before offsets, plus a Medicare levy of $1,400 (2%). Your total before LITO, HECS, or MLS is $13,188 — an effective rate of about 18.8%.

How much tax do I pay on $100,000 in Australia?

On a taxable income of $100,000 for 2025-26, income tax is $20,788 before offsets, plus a Medicare levy of $2,000 (2%). Your total before LITO, HECS, or MLS is $22,788 — an effective rate of about 22.8%.

How much tax do I pay on $400,000 in Australia?

On a taxable income of $400,000 for 2025-26, income tax is $146,138 before offsets — most of it taxed at the top 45% marginal rate. Add $8,000 Medicare levy and you may also owe the Medicare Levy Surcharge if you don't hold private hospital cover. The combined effective rate before MLS is about 38.5%.

How much is the Medicare levy on $100,000?

At 2% of taxable income, a $100,000 income produces a Medicare levy of $2,000. The Medicare Levy Surcharge does not apply at this income level for singles (the threshold is $101,000).

What is the 30% tax bracket in Australia?

For 2025-26, the 30% rate applies to taxable income between $45,000 and $135,000. It is the bracket most full-time salaries fall into. Because rates are marginal, only the income inside that range is taxed at 30% — the slices below it are still taxed at the lower rates.

How much tax do I pay on $120,000 in Australia?

On a taxable income of $120,000 for 2025-26, income tax is $26,788 before offsets, plus a Medicare levy of $2,400 (2%). The total before LITO, HECS, or MLS is $29,188 — an effective rate of about 24.3%.

What is the difference between the Medicare levy and the Medicare Levy Surcharge?

The Medicare levy is 2% of taxable income and is paid by most residents regardless of insurance. The Medicare Levy Surcharge is an extra 1%–1.5% that only applies if your income for MLS purposes exceeds $101,000 (singles) and you don't hold eligible private hospital cover.
