Understanding Australian Tax Brackets 2025-2026: A Complete Guide

Understanding how Australian tax brackets work is fundamental to managing your finances effectively. Whether you're starting your first job, negotiating a salary increase, or planning for retirement, knowing how much tax you'll pay on your income helps you make informed financial decisions. This comprehensive guide explains everything you need to know about the 2025-2026 tax brackets, including the significant changes brought by the Stage 3 tax cuts.

How Australia's Progressive Tax System Works

Australia uses a progressive tax system, which means the more you earn, the higher the rate of tax you pay on your additional income. However, a common misconception is that moving into a higher tax bracket means all your income is taxed at the higher rate. This isn't true.

Instead, your income is divided into portions, and each portion is taxed at its corresponding rate. For example, if you earn $100,000, you don't pay 30% on the entire amount. Instead, the first $18,200 is tax-free, the next portion is taxed at 16%, and so on. This ensures that everyone benefits from the lower rates on the first portions of their income, regardless of their total earnings.

This progressive structure is designed to create a fairer tax system where those who earn more contribute a larger proportion of their income to fund public services, while ensuring lower-income earners keep more of their wages.

The 2025-2026 Tax Brackets Explained

For the 2025-26 financial year (1 July 2025 to 30 June 2026), Australian residents are subject to the following tax rates:

The first bracket covers income from $0 to $18,200, which is completely tax-free. This is known as the tax-free threshold and ensures that low-income earners pay no tax on their first $18,200 of earnings.

Income between $18,201 and $45,000 is taxed at 16 cents for each dollar over $18,200. This means if you earn $45,000, you'll pay $4,288 in tax on this portion of your income.

The third bracket applies to income between $45,001 and $135,000, taxed at 30 cents per dollar over $45,000. This is where most full-time Australian workers fall, making it the largest tax bracket by population.

Income from $135,001 to $190,000 is taxed at 37 cents per dollar over $135,000. At this level, you're paying $31,288 plus 37% on income above $135,000.

Finally, income over $190,000 is taxed at the top marginal rate of 45 cents per dollar over $190,000. At this level, you'll pay $51,638 plus 45% on every dollar above $190,000.

The Stage 3 Tax Cuts: What Changed

The Stage 3 tax cuts, which came into effect on 1 July 2024, represented the most significant changes to Australian tax brackets in decades. Originally designed differently, the legislation was modified to provide greater benefits to low and middle-income earners.

The key changes included reducing the 19% tax rate to 16%, providing immediate relief for workers earning between $18,201 and $45,000. The 32.5% rate was also reduced to 30%, benefiting the large portion of Australians earning between $45,001 and $135,000.

These changes mean that every Australian worker now pays less tax than they did before July 2024. For someone earning the average full-time wage of around $95,000, the annual tax saving is approximately $2,179 compared to the old rates. Lower-income earners see proportionally larger percentage savings, making the revised Stage 3 cuts more equitable than the original proposal.

Calculating Your Tax: A Practical Example

Let's work through a practical example. Suppose you earn $85,000 per year. Here's how your tax would be calculated for 2025-26:

On the first $18,200, you pay $0 in tax. On income from $18,201 to $45,000 (which is $26,800), you pay 16%, equaling $4,288. On income from $45,001 to $85,000 (which is $40,000), you pay 30%, equaling $12,000.

Your total income tax would be $16,288, which represents an effective tax rate of 19.2% on your total income. This is significantly lower than the 30% marginal rate that applies to your highest dollar of income.

The Tax-Free Threshold: Important Considerations

The $18,200 tax-free threshold is available to all Australian residents, but there are some important considerations. If you have multiple jobs, you should only claim the tax-free threshold from one employer. Claiming it from multiple employers will result in being under-taxed throughout the year, leading to a tax debt when you lodge your return.

When starting a new job, you'll complete a Tax File Number declaration form where you indicate whether you want to claim the tax-free threshold. If you already claim it elsewhere, you should select "No" to ensure the correct amount of tax is withheld.

Beyond Income Tax: Medicare Levy

In addition to income tax, most Australian residents pay the Medicare levy of 2% on their taxable income. This funds Australia's public healthcare system. The Medicare levy is calculated separately from income tax and applies on top of the tax amounts shown above.

Low-income earners may receive a reduction or exemption from the Medicare levy. For the 2025-26 year, if you earn below $26,000, you may pay a reduced levy or none at all. The levy phases in gradually between $26,000 and $32,500.

Planning for Your Tax Situation

Understanding tax brackets helps with financial planning in several ways. When negotiating a salary increase, you can calculate exactly how much extra take-home pay you'll receive. When considering overtime or a second job, you'll know your marginal rate and can make informed decisions.

Tax brackets also influence decisions about salary sacrifice arrangements, spouse contributions to superannuation, and timing of income. While tax minimisation strategies should always be discussed with a qualified tax professional, understanding the basics helps you ask the right questions.

Conclusion

Australia's progressive tax system ensures that higher earners pay more while protecting the take-home pay of lower-income workers. The 2025-26 tax brackets, shaped by the Stage 3 tax cuts, provide tax relief across all income levels while maintaining a fair distribution of the tax burden.

Remember, these rates apply to Australian residents only. Non-residents and working holiday makers are subject to different rates. For personalised advice on your tax situation, consult a registered tax agent or the Australian Taxation Office.
