Perth negative gearing explained properly starts with one distinction. Negative gearing is not a strategy, an incentive or a loophole. It is simply the name for a situation where a rental property’s costs exceed the income it produces over a year, and the owner deducts that shortfall against other taxable income.
That is the whole mechanic. The complications come from how the shortfall is calculated, what counts as a cost, and what happens when the property turns positive. Investors who get those three things straight avoid most of the expensive mistakes.
How Perth negative gearing works in practice
Start with gross rent for the financial year. Subtract the expenses you can deduct in the year they are incurred, such as interest on the loan, council rates, water rates, insurance, property management fees, repairs and maintenance, and advertising for tenants.
If the result is a loss, that loss reduces your other taxable income for the year. That is the part people mean when they talk about negative gearing. The benefit is not a payment from the tax office. It is a smaller tax bill at your marginal rate, which means the benefit is larger for higher income earners and larger again for those on the top marginal rate.
Not every cost is deducted the same way. This is where most confusion sits:
- Interest and ongoing expenses are generally deductible each year.
- Capital works, such as a building extension or a structural renovation, are usually claimed over time as capital works deductions rather than immediately.
- Depreciating assets like appliances and carpets are claimed over their effective life, and the treatment differs for new and second-hand assets.
- Capital costs, including stamp duty and the purchase price itself, are not deductible and form part of your cost base instead.
Borrowing costs and loan establishment fees are another category with their own treatment, usually spread across a number of years. Our guide to the strata report is useful context for apartments, where owners corporation costs add to the annual expenses picture.
When it stops working
A property becomes positively geared when rent exceeds deductible expenses. The moment that happens, the situation reverses: you declare the surplus as income and pay tax on it, while the deduction disappears.
That transition usually occurs for one of three reasons. Rents rise faster than costs. Interest costs fall because the loan has been paid down. Or the investor stops claiming interest because they no longer have a loan against the property.
None of those are bad outcomes. A positively geared property with a paid-down loan is generally a better position than a heavily geared one. The mistake is buying on the assumption that negative gearing is a permanent feature of the investment rather than a phase of it.
Investors should also understand that the deduction only reduces tax on income you already pay tax on. Someone with low or no taxable income cannot use the loss, though the timing of deductions and other income sources can affect the outcome. That is a conversation to have with an accountant rather than a purchase decision to make from a blog.
The practical mistakes to avoid
Do not treat the tax deduction as a reason to accept a poor investment. A property losing money only because it was the wrong property, in the wrong place, at the wrong price does not improve because the loss is partly deductible. The deduction softens the loss. It does not reverse it.
Do not neglect records. Every expense needs a receipt and a property allocation for a shared period. Investors who reconstruct a year of claims from memory generally lose part of the deduction, and the onus is on the taxpayer.
Do not assume the rules will remain the same. Property tax treatment has been the subject of sustained political debate for years, and any investor should consider whether the numbers work without the concession. If the purchase only adds up because of the deduction, the risk sits with you.
