Stage 3 Tax Cuts Calculator: Before & After Comparison for FY 2025-26
Wondering exactly how much the Stage 3 tax cuts will save you? Our comprehensive Stage 3 tax cuts calculator reveals the real dollar difference between the old and new income tax systems. Whether you're planning your budget, negotiating a salary, or simply curious about your new take-home pay, this before and after comparison will show you precisely what these tax reforms mean for your wallet in the 2025-26 financial year.
Understanding the Stage 3 Tax Cuts Changes
The Stage 3 tax cuts represent the most significant overhaul of Australia's personal income tax system in over a decade. Effective from 1 July 2024 and fully operational through FY 2025-26, these changes restructure the tax brackets to deliver relief to millions of Australian workers. The core philosophy behind these cuts was to reduce the tax burden on middle-income earners while simplifying the overall tax structure.
The key changes include reducing the 19% tax rate to 16% for incomes between $18,201 and $45,000, lowering the 32.5% rate to 30% and extending this bracket from $45,001 to $135,000, and pushing the thresholds for higher tax rates further up the income scale. The 37% rate now starts at $135,001 instead of $120,001, and the top 45% rate kicks in at $190,001 rather than $180,001. These adjustments mean that for the first time in years, a vast swathe of Australian workers—from $45,000 to $200,000—will eventually fall into the same 30% tax bracket.
Tax Brackets: Before vs After Comparison
To understand exactly how the Stage 3 tax cuts affect you, it's essential to see the side-by-side comparison of the old and new tax brackets. The following table shows the complete transformation of Australia's income tax structure for FY 2025-26 compared to the previous system that applied in 2023-24:
| Taxable Income Range | Old Tax Rate (Pre-2024) | New Tax Rate (2025-26) | Change |
|---|---|---|---|
| $0 – $18,200 | 0% | 0% | No change |
| $18,201 – $45,000 | 19% | 16% | ↓ 3% |
| $45,001 – $120,000 | 32.5% | 30% | ↓ 2.5% |
| $120,001 – $135,000 | 37% | 30% | ↓ 7% |
| $135,001 – $180,000 | 37% | 37% | No change |
| $180,001 – $190,000 | 45% | 37% | ↓ 8% |
| $190,001 and over | 45% | 45% | No change |
As you can see from the comparison table, the biggest winners from the Stage 3 tax cuts are those earning between $120,001 and $190,000. Workers in the $120,000 to $135,000 range see their marginal tax rate drop by a massive 7 percentage points, while those between $180,001 and $190,000 benefit from an 8 percentage point reduction. Even middle-income earners benefit from the 2.5% reduction in the main tax bracket, which now covers a much wider income range.
Real Dollar Savings: Before and After Calculations
While percentage changes are helpful, what really matters is the actual dollar amount you'll save. Our Stage 3 tax cuts calculator shows the precise before and after comparison for various income levels in FY 2025-26. These figures represent your annual tax savings compared to what you would have paid under the old tax system:
| Annual Income | Tax Before Cuts | Tax After Cuts | Annual Saving | Extra Per Fortnight |
|---|---|---|---|---|
| $45,000 | $4,092 | $3,288 | $804 | $31 |
| $60,000 | $8,967 | $7,788 | $1,179 | $45 |
| $75,000 | $13,842 | $12,413 | $1,429 | $55 |
| $90,000 | $19,717 | $18,038 | $1,679 | $65 |
| $100,000 | $22,967 | $20,788 | $2,179 | $84 |
| $120,000 | $29,467 | $27,288 | $2,179 | $84 |
| $135,000 | $35,017 | $32,838 | $2,179 | $84 |
| $150,000 | $40,117 | $36,388 | $3,729 | $143 |
| $180,000 | $51,667 | $47,488 | $4,179 | $161 |
| $200,000 | $60,667 | $56,138 | $4,529 | $174 |
The before and after comparison reveals some interesting patterns. Workers earning between $100,000 and $135,000 all receive the same $2,179 annual benefit—an intentional design feature that provides consistent relief to Australia's core middle-class workforce. Meanwhile, those earning $150,000 and above see substantially larger savings, with the maximum benefit of $4,529 going to those earning $200,000 or more. It's worth noting that these figures represent income tax only and don't include the Medicare levy, which remains at 2% for most taxpayers.
How the Tax Cuts Interact with Other Deductions
When using our Stage 3 tax cuts calculator, it's important to understand how these savings interact with other aspects of your tax situation. If you have a HECS-HELP debt, the tax cuts don't directly affect your compulsory repayment amounts, which are calculated based on your taxable income before tax. However, with more take-home pay each fortnight, you might find it easier to make voluntary repayments to clear your debt faster.
Similarly, the tax cuts create new opportunities for salary sacrifice strategies. With marginal tax rates now lower for many workers, the tax advantage of contributing to superannuation has narrowed slightly, but it remains highly beneficial. For example, if you're earning $90,000 and now paying 30% marginal tax instead of 32.5%, the tax benefit of salary sacrificing into super (taxed at 15%) is still a substantial 15 percentage points. Consider using some of your tax cut savings to boost your super contributions and build long-term wealth while still enjoying improved cash flow.
Using the Tax Cuts in Your Financial Planning
Now that you know exactly how much you'll save with the Stage 3 tax cuts, the next step is deciding what to do with this extra money. For many Australian households, the additional $50 to $170 per fortnight provides welcome relief amid rising cost-of-living pressures. However, financial advisors recommend considering strategic uses for this windfall rather than letting it simply disappear into everyday spending.
Some smart strategies include building an emergency fund if you don't already have one, paying down high-interest debt like credit cards, making additional mortgage repayments to reduce your principal faster, or increasing your super contributions through salary sacrifice. The beauty of the Stage 3 tax cuts is that they deliver savings through your regular pay rather than as a lump sum at tax time, making it easier to incorporate them into your ongoing budget. Use our take-home pay calculator to see your precise after-tax income and plan accordingly.

Whether you're saving $804 on a $45,000 salary or $4,529 on a $200,000 salary, this extra money represents an opportunity to strengthen your financial position. The key is being intentional about how you use these savings.
