Income Tax Cuts Calculator - Australia Federal Budget 2020/21

What This Calculator Does

This calculator estimates the tax savings you may receive under the income tax cuts announced in the Australian Federal Budget for 2020/21. It compares your tax liability under the previous tax rates against the new, legislated rates to show the difference in tax payable.

The tool is designed for individual taxpayers who want a quick, ballpark figure of how the budget changes affect their take-home pay. It focuses specifically on the personal income tax bracket adjustments and the Low Income Tax Offset (LITO) changes that took effect from 1 July 2020.

How the Tax Cuts Work

The 2020/21 Federal Budget accelerated Stage 2 of the government's Personal Income Tax Plan. Two key changes were introduced:

• Bracket adjustment: The 19% tax bracket threshold increased from $37,000 to $45,000. This means more of your income is taxed at the lower 19% rate instead of jumping to the 32.5% rate.
• LITO increase: The Low Income Tax Offset increased from $445 to $700. This offset reduces the amount of tax you owe, and it phases out at a slower rate, meaning more low- and middle-income earners receive the full benefit.

These changes were backdated to apply from 1 July 2020, so they are reflected in your tax return for the 2020/21 financial year.

How to Use the Calculator

1. Enter your estimated taxable income for the 2020/21 financial year.
2. The calculator automatically applies both the old and new tax rates and offsets.
3. Review the comparison: your tax under the old system, your tax under the new system, and your estimated savings.

No personal identifying information is required. The result is an estimate only and does not account for other deductions, offsets, or Medicare Levy surcharges.

Understanding Your Results

The output shows three key figures:

• Tax under previous rates: What you would have paid without the budget changes.
• Tax under new rates: What you owe after the bracket adjustment and LITO increase.
• Estimated savings: The difference between the two.

For most taxpayers earning between $45,000 and $120,000, the savings will be most noticeable. Those earning below $45,000 benefit primarily from the increased LITO. Higher-income earners above $120,000 see a smaller relative benefit because the bracket change only affects the portion of income between $37,000 and $45,000.

Common Misunderstandings

• This is not a refund estimate. The calculator shows a reduction in tax payable, not the amount you will receive as a refund. Your actual refund depends on your total tax withheld and other factors.
• The savings are not cash in hand. The tax cut is built into the ATO's withholding schedules. Most employees saw the benefit through slightly higher pay packets from October 2020 onwards, not as a lump sum.
• It only applies to 2020/21. These rates are specific to that financial year. Later budgets introduced further changes for subsequent years.

Limitations

This calculator provides an estimate based on taxable income alone. It does not account for:

• The Medicare Levy (typically 2% of taxable income)
• The Medicare Levy Surcharge (if applicable)
• Other tax offsets (e.g., Senior and Pensioners Tax Offset, Zone Offset)
• Deductions, capital gains, or investment income
• The 37% and 45% tax brackets (these remained unchanged)
