General information for Australian investors — not tax or financial advice.
Australian ContentLegislation & currency: Reflects current ATO treatment of rental-property deductions and the direction of proposed negative gearing reforms. Where changes apply depends on grandfathering arrangements, eligible new builds and affected established investments.
The investor question
You hold an investment property with a mortgage against it, and you have (or expect to have) roughly $50,000 of capital available — from savings, an offset balance, a maturing investment or released equity. The decision is simple to state and hard to settle: do you pay that $50,000 off the investment loan, or keep it available to invest elsewhere?
The negative gearing changes shift the arithmetic slightly, because they change how a property loss is treated for tax. But that treatment is only one variable in the decision — and rarely the largest one.
What the negative gearing changes alter
Negative gearing describes the position where the deductible costs of holding a rental property — most significantly loan interest — exceed the rental income, producing a loss. The relevant question for this decision is how that loss can be used, and whether it can still be offset against other income in the way an investor may previously have assumed.
Where the treatment of property losses becomes less generous, the after-tax cost of carrying investment debt rises. That makes the interest you would save by paying down the loan worth relatively more, and the tax benefit of holding the debt worth relatively less. Whether that shift applies to your property can depend on whether it is covered by grandfathering arrangements, whether it is an eligible new build, or whether it is an affected established residential investment.
What the changes don't determine
A change in tax treatment does not tell you where your capital earns the best risk-adjusted return. Paying down the loan produces a certain, after-tax saving equal to your interest rate on the amount repaid. That is a genuine return — but not automatically the highest one available to you.
- the interest rate saved by reducing the loan, after tax;
- the return you realistically expect from deploying the capital elsewhere, after tax;
- the value you place on liquidity, flexibility and a lower debt balance; and
- your tolerance for the risk attached to each alternative.
Model the investment decision
Rather than declaring a winner, set the two options side by side and compare the variables that actually move the outcome.
| Variable to compare | Keep $50,000 available / invest elsewhere | Pay $50,000 off the investment loan |
|---|---|---|
| Immediate return | Whatever the alternative investment earns, after tax and after risk | A certain saving equal to your loan rate on $50,000, after tax |
| Property cash flow | Unchanged — interest continues on the full balance | Improves — lower interest each period reduces the holding cost |
| Liquidity | Capital stays accessible for opportunities or emergencies | Capital becomes tied up until refinanced or sold |
| Debt & risk | Higher balance retained; more exposure to rate rises | Lower balance; reduced sensitivity to rate movements |
| Tax interaction | Depends on the alternative investment and your circumstances | Reduces deductible interest — value depends on how losses are now treated |
The honest comparison is between the after-tax interest saved and the after-tax return you expect elsewhere, weighted by how much you value liquidity and a lower debt balance. If the loan interest saved exceeds what you would confidently earn elsewhere, paying down looks stronger; if not, keeping the capital deployed may serve the portfolio better.
Questions for your accountant
“Given how property losses are now treated, how does the after-tax cost of my investment loan interest change?”
“Does my property fall under grandfathering arrangements, or is it an affected established investment?”
“If I reduce the investment loan and later re-borrow, how might the purpose of that new borrowing affect deductibility?”
“How should I keep records if I redraw or restructure this loan?”
