General information only. This calculator uses simplified assumptions. It does not model principal and interest loan reduction, vacancy periods, or land tax. Depreciation estimates require a quantity surveyor report. The tax refund assumes the rental loss can be offset against your salary income in full (check with your accountant if your situation is complex). Not financial advice.

How Negative Gearing Works in Australia

Negative gearing occurs when the deductible costs of holding an investment property — mortgage interest, council rates, property management fees, repairs, depreciation — exceed the rental income it generates. The ATO allows you to offset this net rental loss against your other taxable income, including your PAYG salary. This reduces your total assessable income and, at higher tax brackets, produces a meaningful refund at tax time.

The tax benefit scales with your marginal rate. On an income of $120,000, your marginal rate is 37% (plus 2% Medicare levy). A $12,000 annual rental loss — $1,000 per month shortfall between rent collected and loan interest paid — generates a $4,680 tax saving. On the same loss, a taxpayer earning $50,000 (marginal rate 19%) saves only $1,980. This asymmetry is why negative gearing is most effective for high-income earners and why lower-income investors should carefully model whether the tax benefit justifies the cash flow shortfall.

Capital growth is the non-negotiable companion to negative gearing. The strategy only makes sense if the property appreciates enough over your holding period to offset accumulated losses, transaction costs (stamp duty, agent's commission at sale), and the CGT liability on your gain. At current ATO rates, individuals held a property for more than 12 months receive a 50% CGT discount, meaning only half the capital gain is added to assessable income — a significant offset. However, proposed indexation reforms (flagged for 2027) may alter this calculation for new investors.

Frequently Asked Questions

Does negative gearing still make sense at lower income levels?
At the 19% marginal rate (income $18,201–$45,000), the tax refund on a $10,000 rental loss is only $1,900 — barely $37 per week. Meanwhile, the cash flow shortfall of $192 per week must be funded from after-tax income. For lower-income investors, the numbers often work better with positively geared properties that generate cash flow, or through structure (e.g. a family trust distributing income to lower-rate beneficiaries). The tax benefit of negative gearing is maximised at the 45% bracket where a $10,000 loss saves $4,700 in tax.
What expenses can I deduct against rental income?
The ATO allows deductions for: loan interest (the largest component), council rates and water charges, property management fees (typically 7–10% of rent), insurance premiums, repairs and maintenance (not capital improvements), advertising costs, stationery and postage, travel to inspect the property (limited since 2017 for residential), and depreciation on qualifying assets via a quantity surveyor's report. Capital improvements (e.g. new kitchen, bathroom renovation) are not immediately deductible — they are depreciated or added to the cost base for CGT purposes.
How might CGT reforms affect negative gearing investors?
The 50% CGT discount for assets held over 12 months has been in place since 1999 and is a cornerstone of the current negative gearing model. Various policy proposals — including reverting to the pre-1999 indexation method for new investors — have been discussed for a 2027 budget. Under indexation, only the portion of gain above CPI inflation would be taxed, which benefits long-term holders in high-growth markets but reduces the benefit for investors who rely on large nominal gains over shorter periods. Existing investors are generally expected to be grandfathered under any transitional provisions.
