Negative gearing calculator for Australian property investors

Because your property doesn’t exist in isolation from the rest of your tax.

More than a basic negative gearing calculator
Most negative gearing calculators give you an estimate based on a few figures you enter once.
TaxTank is different. It brings together your actual property income and expenses, depreciation, employment income, other deductions and investment income, then applies Australian tax rules to calculate your overall individual tax position.
As your income and expenses change throughout the year, your calculated tax position changes with them.
We have used Xero for my properties but for specific property functionality TaxTank is better and the pricing far outweighs what we were paying. If I could give 10/10 I would. Thank you so much!!!

Negative gearing is changing from 1 July 2027
The changes to negative gearing are expected to apply from 1 July 2027, creating different tax treatments for some residential investment properties.
Existing and newly acquired properties may need to be treated differently, meaning investors with multiple properties could have different negative gearing rules applying across the same portfolio.
TaxTank is designed to apply the appropriate Australian tax rules to each property and financial year, without you having to manually maintain different calculations.

TaxTank automatically applies the correct tax rules when they come into effect
The changes to negative gearing will make property tax more complex than ever. Depending on when an investment property was purchased, different tax rules may apply across the same portfolio. Add depreciation, loan interest, capital improvements, borrowing expenses, capital gains tax and different ownership structures, and a basic negative gearing calculator or spreadsheet can only tell you so much.
TaxTank goes beyond a basic negative gearing calculator. It brings together your actual property income and expenses with your other income and deductions, then applies Australian tax rules to calculate your overall tax position throughout the year.
As the new negative gearing rules take effect, TaxTank will apply the correct tax treatment to each property, so you can see the true impact of your investments as part of your complete financial picture.

Frequently asked questions
What is a negative gearing calculator?
A negative gearing calculator estimates the tax impact of an investment property when deductible property expenses exceed rental income. Most calculators use a small number of figures to provide a one-off estimate. TaxTank goes further by calculating your property alongside your other income, deductions and investments to show its impact on your overall tax position.
How is TaxTank different from a basic negative gearing calculator?
Basic calculators generally rely on estimates entered at a single point in time. TaxTank uses your actual rental income, property expenses, loan interest, depreciation and other tax information, together with your other income and deductions, to calculate your individual tax position throughout the year.
Does the TaxTank negative gearing calculator include my salary and other income?
Yes. This is an important difference. Negative gearing affects your overall taxable income, so TaxTank calculates your property alongside your employment income and other income and deductions rather than treating the property in isolation.
Can I calculate negative gearing for multiple investment properties?
Yes. TaxTank lets you manage multiple investment properties individually, including their income, expenses, depreciation and ownership details, while calculating their combined effect on your overall tax position.
Does the negative gearing calculator include depreciation?
Yes. TaxTank includes property depreciation as part of the property’s tax calculations. You can manage depreciation schedules alongside your other property income and deductible expenses.
Will TaxTank calculate the new negative gearing rules?
TaxTank applies Australian tax rules by financial year and is being updated to account for the new negative gearing rules when they take effect. This means the appropriate treatment can be applied to each property rather than relying on you to manually adjust a basic calculator.
How do I manage investment properties under different negative gearing rules?
TaxTank keeps each investment property separate and automatically applies the appropriate tax treatment based on the relevant legislation. Whether your portfolio includes grandfathered properties, newly acquired properties or both, TaxTank calculates each one correctly while combining everything into a single live tax position. Unlike property-only apps, you can see how your investment properties affect your overall tax outcome across all of your income and deductions.
Do the changes to negative gearing affect capital gains tax?
Negative gearing and capital gains tax are separate areas of Australian tax law, but both can significantly affect the overall return on an investment property. TaxTank helps you manage both by tracking rental income, expenses, depreciation, purchase costs, improvements and capital gains in one place.
Why have the changes to negative gearing made property tax more complicated?
The changes to negative gearing mean some investors may need to manage different tax treatments across the same portfolio. Combined with depreciation, loan interest, capital improvements, capital gains tax and different ownership structures, property tax has become increasingly complex. TaxTank simplifies this by applying the correct Australian tax rules in the background and calculating your tax position throughout the year.
What happens if the negative gearing rules change again?
Australian tax legislation continues to evolve. TaxTank is designed to keep up with those changes by updating the software to reflect new tax legislation, helping ensure your calculations remain accurate across different financial years without relying on manual spreadsheets or formulas.
Does TaxTank automatically calculate negative gearing?
Yes. TaxTank automatically calculates your rental income, deductible expenses, loan interest and overall tax position throughout the financial year using Australian tax rules. Because TaxTank manages all major income types, including employment income, sole trader income, investment income, shares and cryptocurrency, you’re able to see the true tax benefit of negative gearing as part of your complete financial picture, not just in isolation.
Can I see how the negative gearing changes affect my overall tax position with TaxTank?
Yes. Unlike property-only software, TaxTank calculates your complete tax position by combining your employment income, sole trader income, investment properties, shares, cryptocurrency and other investments. This allows you to see the true impact of negative gearing on your overall tax, not just your rental property.
Why is TaxTank different from other property investment software?
Most property investment apps only calculate rental property income and expenses, while accounting software often focuses on business finances. TaxTank is the only Australian software that brings together your employment income, investment properties, sole trader income, shares, cryptocurrency and other investments into one live tax calculation. This gives you a complete view of your tax position, including the real impact of negative gearing across your entire financial situation.
Why is TaxTank better than a property investment spreadsheet for managing the changes to negative gearing ?
Spreadsheets require you to manually update formulas, apply changing tax rules and calculate the tax impact yourself. TaxTank automatically applies the correct tax treatment, imports your transactions through secure bank feeds and calculates your live tax position, giving you confidence that your investment properties are being managed correctly.
Does TaxTank replace my spreadsheet?
Yes. TaxTank tracks property purchase costs, improvements, selling costs and capital gains tax, making it easier to manage both ongoing property tax and future property sales.
Is TaxTank only for property investors?
No. While TaxTank includes powerful tools for managing investment properties and the negative gearing changes, it’s also the only Australian software that combines employment income, sole trader income, investment properties, shares and cryptocurrency into one live tax calculation. That means you can see the complete picture of your finances and tax position all year round.
