What is negative gearing?
A rental property is negatively geared when the costs of owning it, including loan interest, are more than the rent it earns. This produces a net rental loss.
Under current rules, you can deduct that net rental loss against your other income, such as salary or wages, which reduces your taxable income and the tax you pay. This calculator estimates your net rental position and the tax effect. It is a model and general information, not tax advice.
Negative gearing is changing under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (Act No. 49 of 2026, Royal Assent 26 June 2026). From 1 July 2027, it will be limited to newly built homes. Losses on established residential properties bought after 7:30pm AEST on 12 May 2026 will only be deductible against residential property income or capital gains, not against salary. Properties held before that date are not affected. This calculator uses the current rules.
How to use this calculator
Enter your rental income
Use the annual rent you expect to receive.
Add your expenses
Include loan interest, management fees, rates, insurance and maintenance.
Enter your taxable income

The calculator shows your net rental position and the estimated tax effect.
How this calculator works
The calculator subtracts your deductible rental expenses from your rental income to find your net rental position. If expenses are higher than income, the result is a net rental loss. It then estimates the tax effect of that loss at your marginal tax rate.
Assumptions used
Only the interest portion of loan repayments is deductible, not the principal. The tax effect is estimated using the FY2026-27 income tax rates and the FY2025-26 Medicare levy, the latest the ATO has published, applied to the change in your taxable income. Depreciation is a non-cash deduction and is estimated separately if included. It does not apply the negative gearing changes that take effect from 1 July 2027, and it is not tax advice.
Worked example
An investor receives $26,000 a year in rent. Their deductible expenses are $38,000, made up mostly of loan interest, plus management fees, council rates, insurance and maintenance.
The net rental loss is $12,000. If the investor's marginal tax rate is 37 percent plus the 2 percent Medicare levy, the loss reduces their tax by about $4,680. The after-tax cost of holding the property that year is the $12,000 loss less the $4,680 tax saving, which is about $7,320.
The tax saving depends on your marginal tax rate. A higher marginal rate produces a larger saving from the same loss, but the property still costs you money to hold each year.
What changes your negative gearing position
Several things change the size of the annual loss and the tax saving it produces. The main ones are:
Rental income
The rent you receive. Higher rent reduces the loss, and if it exceeds expenses the property is positively geared and the net income is taxed.
Loan interest
Interest on the loan used to buy the property is deductible. Only the interest portion is deductible, not the principal you repay.
Other rental expenses
Deductible expenses include property management fees, council rates, water charges, insurance, and repairs and maintenance.
Depreciation
Depreciation on the building and on fixtures can be claimed as a non-cash deduction, which increases the loss without a cash outlay. See the Depreciation calculator.
Your marginal tax rate
The loss reduces your taxable income, so the tax saving depends on your marginal rate. A higher marginal rate produces a larger saving from the same loss.
Changes from 1 July 2027
From 1 July 2027, negative gearing is limited to newly built homes. For established residential properties bought after 7:30pm AEST on 12 May 2026, losses can only be deducted against residential property income or gains, not salary. Excess losses can be carried forward.

Frequently asked questions
A rental property is negatively geared when its deductible costs, including loan interest, are more than the rent it earns, which produces a net rental loss. Under current rules that loss can reduce your other taxable income, such as salary.
Common deductible rental expenses include loan interest, property management fees, council rates, water charges, insurance, and repairs and maintenance. Only the interest portion of loan repayments is deductible, not the principal.
The net rental loss reduces your taxable income, so the saving depends on your marginal tax rate. A loss of $10,000 for someone on a 37 percent marginal rate plus the 2 percent Medicare levy reduces tax by about $3,900. The property still costs you money to hold.
Yes. From 1 July 2027, negative gearing is limited to newly built homes. For established residential properties bought after 7:30pm AEST on 12 May 2026, losses can only be deducted against residential property income or capital gains, not against salary. Excess losses can be carried forward.
Properties held before 7:30pm AEST on 12 May 2026 are not affected by the change and can continue to be negatively geared under current rules until sold. This includes properties under contract before that time.
Yes. Negative gearing can apply to other investments, such as shares bought with borrowed money, where the interest and costs exceed the income. The 1 July 2027 residential property change does not remove negative gearing for these other assets.
