45% Tax Bracket 2025: A Complete Guide for High-Income Earners

If you're earning a high income in Australia, understanding the 45% tax bracket is essential for effective financial planning. For the 2025-26 financial year, this top marginal rate applies to income above $190,000—a threshold that was adjusted as part of the Stage 3 tax cuts. Whether you're a senior professional, business owner, or climbing the corporate ladder, knowing how this bracket affects your take-home pay can help you make smarter decisions about salary packaging, investments, and retirement planning.

What Is the 45% Tax Bracket in 2025?

The 45% tax bracket is Australia's highest marginal tax rate, reserved for the top income earners. For the 2025-26 financial year, this rate applies to every dollar you earn above $190,000. It's important to understand that this is a marginal rate—meaning you only pay 45% on the income that falls within this bracket, not on your entire salary. This distinction is crucial for high-income earners when evaluating bonus opportunities, investment returns, or additional work.

The threshold for entering the 45% bracket was increased from $180,000 to $190,000 as part of the Stage 3 tax reforms that took effect on 1 July 2024. This change means that high-income earners now keep more of their money in the lower 37% bracket before the top rate kicks in. For someone earning $200,000, this adjustment saves approximately $1,000 in tax compared to the previous system. Understanding where you sit in the tax brackets helps you calculate exactly how much of your next dollar you'll actually keep after tax.

When you factor in the 2% Medicare levy that applies to most residents, your effective marginal rate in this bracket becomes 47%. Additionally, high-income earners without private health insurance may face the Medicare Levy Surcharge, which can add another 1% to 1.5% to your total tax burden. This makes the total marginal rate potentially as high as 48.5% for some taxpayers.

FY 2025-26 Tax Brackets: Where Does the 45% Rate Fit?

To fully understand the 45% bracket, you need to see how it fits within Australia's complete progressive tax system. The following table shows all five tax brackets for Australian residents in the 2025-26 financial year, illustrating exactly where your income falls and how much tax you'll pay at each level.

These rates represent the current legislation and incorporate the Stage 3 tax cuts that reshaped Australia's tax landscape. The changes particularly benefit middle and high-income earners by reducing rates in the lower brackets and raising the thresholds for higher rates. Use our income tax calculator to see exactly how these brackets apply to your specific situation.

Note: These rates exclude the 2% Medicare levy. High-income earners may also be subject to the Medicare Levy Surcharge (1-1.5%) if they don't have appropriate private health insurance. Use our Medicare levy calculator for precise figures.

How Much Tax Do You Pay in the 45% Bracket?

Let's break down exactly what entering the 45% tax bracket means for your finances. If you earn $190,000 or less, you won't pay any tax at the 45% rate. But once your income crosses that threshold, every additional dollar is taxed at 45 cents. Here's how the math works for various high-income scenarios in the 2025-26 financial year.

Consider Michael, a senior executive earning $220,000 per year. His tax calculation works as follows: the first $18,200 is tax-free, the portion from $18,201 to $45,000 incurs $4,288 in tax, the $45,001 to $135,000 portion adds $27,000, the $135,001 to $190,000 range contributes $20,350, and the final $30,000 above $190,000 is taxed at 45%, adding $13,500. His total income tax is $65,138, plus $4,400 for the Medicare levy, bringing his total tax to $69,538. This gives him an effective tax rate of approximately 31.6%—significantly lower than his 45% marginal rate.

The table below shows tax calculations for various income levels at and above the 45% bracket threshold. These figures include the 2% Medicare levy but exclude other obligations like HECS-HELP repayments or the Medicare Levy Surcharge.

Tax Strategies for High-Income Earners

When you're paying 45 cents in every dollar above $190,000 to the tax office, legitimate tax minimisation strategies become increasingly valuable. The most effective approach for most high-income earners is salary sacrifice into superannuation. Concessional super contributions are taxed at just 15%, creating a 30% tax saving on every dollar you contribute (or 32.5% if you include the Medicare levy savings).

For the 2025-26 financial year, the concessional contributions cap is $30,000. If you're earning $250,000 and contribute the maximum $30,000 to super through salary sacrifice, you save approximately $9,000 in tax compared to taking that income as salary. Even contributing $10,000 saves around $3,000 annually. This strategy not only reduces your immediate tax burden but also grows your retirement savings in a tax-advantaged environment where investment earnings are taxed at only 15%.

Other strategies include negative gearing on investment properties, prepaying deductible expenses before 30 June, and ensuring you claim all eligible work-related deductions. High-income professionals should also consider income protection insurance premiums (which are tax-deductible), charitable donations, and investment in tax-effective structures. However, be aware that very high-income earners may face Division 293 tax, which adds an additional 15% tax on concessional super contributions if your income exceeds $250,000.

The Medicare Levy Surcharge: An Additional Consideration

High-income earners face an extra tax consideration that doesn't apply to most Australians: the Medicare Levy Surcharge (MLS). If you earn above $97,000 as a single person or $194,000 as a couple or family (with higher thresholds for each dependent child), and you don't have appropriate private hospital insurance, you'll pay an additional 1% to 1.5% on your total income. For someone earning $200,000 without private health insurance, this means an extra $2,000 to $3,000 in tax.

The MLS rates are tiered: 1% for singles earning $97,001-$113,000 (families $194,001-$226,000), 1.25% for singles $113,001-$151,000 (families $226,001-$302,000), and 1.5% for singles above $151,000 (families above $302,000). For high-income earners in the 45% tax bracket, taking out basic private hospital cover often costs less than the surcharge, making it a financially sensible decision even if you prefer using the public health system. Use our Medicare levy calculator to determine exactly what you'll owe based on your income and insurance status.

Summary and Key Takeaways

The 45% tax bracket applies to Australian residents earning above $190,000 in the 2025-26 financial year. While this is the highest marginal rate in Australia's tax system, remember that it only applies to income above this threshold—not your entire salary. Your effective tax rate will always be significantly lower than 45%, and the new $190,000 threshold (up from $180,000) means you keep more money in the 37% bracket than in previous years.

For high-income earners, proactive tax planning is essential. Strategies like salary sacrifice to superannuation, obtaining private health insurance to avoid the MLS, and maximising deductible expenses can save thousands of dollars annually. The 15% tax rate on super contributions versus 45% (plus Medicare levy) on income creates a compelling case for building wealth through super, especially as you approach retirement age.
