Why deduction timing matters in the negative gearing debate
Property investors are being urged to focus on how quarantining rental losses could reshape cash flow, deductions and long-term tax planning.
Negative gearing is back at the centre of the pre-budget debate, and for property investors, the impact of any reform would come down to the detail.
One possible approach the government might take in reforming negative gearing is to contain losses within an investment, known as quarantining losses.
While this is not a confirmed policy and negative gearing may remain unchanged, quarantining is one model that could affect when investors can access deductions.
Quarantining means rental losses may no longer reduce tax payable on other income, such as salary or wages, and may instead be limited to the investment property itself.
The key question is whether unused losses can be carried forward and used in future years when, and if, the property becomes positively geared.
Quarantining rental losses in practice
For a property investor who earns $35,000 in rent during the year and has $45,000 in property deductions, this results in a $10,000 loss.
Under current negative gearing rules, that $10,000 loss may generally be used to reduce the investor’s taxable income from other sources, such as salary or wages. For an investor on a 37 per cent marginal tax rate, this could reduce tax by $3,700.
Under a quarantined loss model, the same $10,000 loss may not be available to reduce tax payable on salary or wages. Instead, it may be carried forward and applied against future income from that property.
For example, if the property becomes positively geared in a later year and produces a $6,000 taxable profit, the investor may be able to use $6,000 of the carried-forward loss to reduce taxable rental income to nil. The remaining $4,000 loss may continue to be carried forward, depending on how the rules are written.
In this scenario, the deduction is delayed rather than removed. The investor may still benefit from the deduction in the future, but they lose the immediate cash flow support that would usually help reduce holding costs.
Some market commentary suggests this could place upward pressure on rents in certain conditions, although outcomes depend on a range of factors.
Depreciation can play an important role in this scenario because it may influence the size and timing of a property’s taxable position across multiple years.
It is generally the second largest tax deduction available to property investors after loan interest and can include capital works, such as the building’s structure, as well as plant and equipment assets.
Future-proofing property records
If rental losses were quarantined, investors would need to understand not only what they can claim in the current income year, but also what may need to be carried forward. This makes accurate, long-term record keeping even more important.
A tax depreciation schedule helps identify eligible depreciation deductions and supports discussions with an accountant about how those deductions are treated over time.
Records may also matter when investors renovate. Renovation work can change the timing and nature of tax claims, particularly where a project includes both structural work and new assets. A depreciation schedule prepared before renovations may help identify items with remaining value, while an updated schedule after renovations can help capture new eligible deductions.
If deduction timing changes, investors may need a clearer view of their property’s full tax position across the ownership period.
How property investors can prepare
There is no confirmed change to negative gearing, and investors should not make decisions based on speculation.
A practical step is to understand your current position. This includes rental income, interest costs, other deductible expenses, depreciation, renovation history and whether losses may be used now or later.
If deduction timing changes, investors may benefit from having a clear view of their property’s full tax position across the ownership period.
A tax depreciation schedule can help investors identify eligible depreciation deductions, maintain accurate records and speak with their accountant from a more informed position.
If negative gearing reform is considered, investors should look beyond the headline and focus on the detail: which deductions remain available, when they can be used and how any unused losses are treated.
