Negative Gearing Changes: What Property Investors Need to Know
A practical cash flow guide to the proposed 2026 Budget negative gearing changes, including new builds, grandfathered established homes, and post-reform established purchases.
Negative gearing scenarios to compare
- New build: model immediate loss offset where the property genuinely adds housing supply and satisfies the policy settings.
- Established - grandfathered: model immediate loss offset for established residential property already held, or contracted before 12 May 2026 at 7:30pm AEST.
- Established - post reform: model no immediate tax benefit from a rental loss; instead, show the loss as carried forward for future residential property income or gains.
What negative gearing means
Negative gearing usually describes a rental property where deductible costs, such as interest and eligible holding expenses, are higher than rental income. Under current settings, that loss can often reduce other taxable income, which can create a tax benefit for the owner.
What the 2026 Budget factsheet proposes
The Australian Government factsheet says the proposed change starts from 1 July 2027 and focuses residential negative gearing on new builds. Existing residential property held before 12 May 2026 at 7:30pm AEST is expected to be grandfathered, while later established purchases have losses carried forward rather than immediately offset against salary or other income.
Why this changes cash flow planning
Two properties can have the same rent, loan, and expenses but different after-tax cash flow depending on the policy scenario. A new build or grandfathered established home may show an estimated tax benefit when the rental result is negative. A post-reform established home may show the same accounting loss, but with that loss carried forward instead of improving this year's cash flow.
Principal repayments are different
Principal repayments still leave your bank account, so they matter for cash flow. But they are generally not deductible expenses. That is why a cash flow calculator should separate actual loan cash paid from deductible interest.
How to use the cash flow calculator
Compare the same property under new build, established grandfathered, and established post-reform scenarios. Then stress test the weekly rent, interest rate, strata, council rates, and maintenance so you can see whether the property still works before relying on a tax outcome.
Key points
- The Budget factsheet proposes that, from 1 July 2027, negative gearing for residential property is mainly limited to new builds.
- Established residential properties held, or contracted to buy, before 12 May 2026 at 7:30pm AEST are expected to be grandfathered.
- For established homes bought after that time, rental losses may be carried forward instead of immediately offsetting salary or other income.
- Principal repayments affect cash flow, but are not normally deductible in the rental tax result.
