Tax brackets in Australia: Rates, thresholds and how marginal tax works

What are tax brackets in Australia

Australia runs a progressive tax system. As your income grows, it moves through a series of brackets, and each bracket carries its own rate. You don't pay that top rate on your entire income, only on the slice that falls inside that bracket.

Think of it as a set of buckets stacked on top of each other. Your income fills the first bucket, then spills into the next, then the next. Each bucket has a different tax rate attached, and only the dollars sitting in a bucket get taxed at that bucket's rate. The ATO tax bracket rates for residents are applied progressively across different income brackets.

This is the part people get wrong most often. A pay rise that pushes you into a higher bracket can never leave you worse off. However, crossing into a higher income bracket can sometimes affect your broader take-home position through things like higher HELP repayments, the Medicare Levy Surcharge, or changes to income-tested government benefits and subsidies. Even with these factored in, earning more generally leaves you ahead, but it's worth keeping the full picture in mind.

The higher rate applies only to income above the threshold, not to every dollar you earn. Earning more always leaves you with more in your pocket after tax, even once you've crossed into a new bracket.

For the current 2026-27 financial year, the resident individual tax brackets are:

What is the tax free threshold amount in Australia

If you're a resident for tax purposes for the full year, you don't pay tax on your first AUD $18,200. That's the tax-free threshold amount, and you claim it through your tax file number declaration when you start a job.

But here's where people trip up: the threshold applies to your taxable income, not everything that lands in your bank account. Taxable income is what's left after allowable deductions. If you operate through a company, corporate profits are taxed at the company rate first - meaning only the salary or dividends you actually draw down count toward your personal taxable income

One more wrinkle: if you only became an Australian tax resident partway through the year, you may not get the full AUD $18,200. The threshold gets pro-rated based on when residency started.

What is marginal tax rate Australia

Your marginal tax rate is the tax you'd pay on your next dollar of income - not on everything you earn. It's different from your average tax rate, and people mix the two up all the time.

Take someone earning AUD $100,000 in 2026-27. They sit in the 30% bracket. But that doesn't mean 30% of their entire $100,000 goes to tax - only the portion that falls in that bracket does. The tax is calculated progressively:

• AUD $0-AUD $18,200: 0%
• AUD $18,201-AUD $45,000: 15%
• AUD $45,001-AUD $100,000: 30%

The income tax before other considerations is therefore: AUD $4,020 + 30% × (AUD $100,000 - AUD $45,000)

That comes to AUD $20,520. The average income tax rate is therefore around 20.5%, rather than 30%.

A 2% Medicare levy may also apply, which would add another AUD $2,000 in this simplified example. This is why looking only at the marginal tax rate can give you the wrong impression about how much tax you actually pay.

Medicare levy calculation

The Medicare levy is generally calculated separately from income tax. For a taxpayer with AUD $100,000 in taxable income who is liable for the full 2% levy:

This is just an example. Some people pay less Medicare levy, or none at all, while others get hit with an extra surcharge, depending on their situation. So your actual tax bill could look a bit different.

Medicare levy vs medicare levy surcharge

The Medicare levy and Medicare Levy Surcharge (MLS) are different. The MLS can apply to higher-income taxpayers who do not have an appropriate level of private patient hospital cover, while the standard Medicare levy generally applies separately.

Resident vs foreign resident rates

When reviewing the tax brackets in Australia apply to individuals, your residency status for tax purposes changes everything about which rates apply.

Australian residents get the tax-free threshold and offsets like LITO. Foreign residents get neither. Instead, non-residents pay 30% on income up to AUD $135,000, then 37% up to AUD $190,000, then 45% above that. No Medicare levy either - makes sense, since non-residents generally can't access Medicare in the first place.

Working holiday makers get their own lane. They pay 15% on the first AUD $45,000, then slide onto the standard non-resident scale from there. Working holiday makers follow a distinct tax scale:

• Up to AUD $45,000: 15%
• AUD $45,001 to AUD $135,000: 30%
• AUD $135,001 to AUD $190,000: 37%
• Above AUD $190,000: 45%

Note: Actual tax rates can vary depending on how visa status interacts with individual tax residency rules and applicable double tax treaties.

For founders moving to Australia (or navigating cross-border engagements), getting residency status sorted early is critical. Hiring someone physically overseas introduces complex source-of-income rules, payroll obligations, and treaty questions rather than just standard Australian tax brackets.

For individuals moving here, the ATO doesn't just count days; residency is determined by four separate legal tests (the resides test, domicile test, 183-day test, and Commonwealth superannuation fund test). As outlined in ATO guidance like TR 2023/1, your physical presence, intent, business or employment ties, assets, and social arrangements all dictate how you're taxed.

The current tax brackets are not the same as the rates that applied several years ago:

A simple way to estimate your income tax

This Australian income tax calculation guide shows you how to estimate your tax liability using the current brackets:

• Work out your assessable income: Add the income you need to declare for the financial year.
• Subtract allowable deductions: This gives you your taxable income.
• Apply the relevant tax brackets: Each portion of taxable income is taxed at the applicable marginal rate.
• Account for offsets: Eligible offsets can reduce the tax payable.
• Add applicable levies: The Medicare levy and, where relevant, other charges can affect the final amount.
• Compare the result with tax already withheld: Your employer may have withheld tax from your pay throughout the year. Your final tax return reconciles what was withheld with your actual tax liability.

Compare the result with tax already withheld: Your employer may have withheld tax from your pay throughout the year through PAYG withholding. However, withholding is only an estimate - your final tax liability is calculated only when you lodge your return. Your end-of-year tax assessment reconciles what was withheld against your actual tax liability, which is why the amount on your payslip is rarely the exact final amount you pay for the year.

Do Australian tax brackets apply to business income?

Whether business earnings are taxed at individual rates depends entirely on the structure of your business. The table below outlines how different entities handle income tax:

Why this matters when you're running a business

If you're drawing a salary from your own company, distributing investment returns through a trust structure, or assessing how business earnings translate into personal wealth, understanding the split between corporate and personal tax regimes is critical.

For business owners, personal income tax and company tax operate under entirely separate frameworks. How money flows out of a business - whether through salary, director's fees, dividends, superannuation contributions, or trust distributions - carries vastly different tax consequences. Furthermore, casual income splitting with a spouse is heavily restricted by strict Australian Taxation Office (ATO) rules, such as Personal Services Income (PSI) provisions and anti-avoidance laws (including Section 100A), meaning any structural setup must reflect genuine commercial reality and actual work performed.

Navigating how personal and corporate tax regimes intersect is critical for visibility, but managing the day-to-day numbers shouldn't pull you away from building. Aspire helps founders stay ahead of cash flow with automated accounting tools, multi-currency expense tracking that eliminates manual data entry, and faster book-closing cycles. Clean, real-time financial data gives you the clarity you need to forecast accurately and run your business with confidence.

None of this replaces advice from a registered tax agent. Your business setup, where you live, and where your income comes from - they all change the numbers. Think of this as your starting map, not the final word. Take your specific numbers to someone who knows your books.
