Unlock the secrets to timing property investments

The 2026-27 Federal Budget has introduced reforms that fundamentally changed the timing question for property investors. If you purchased an established residential property before 12 May 2026, you retain access to the 50% capital gains discount and full negative gearing deductions. If you purchase from 13 May onwards, those arrangements end from 1 July 2027.

When Budget Changes Actually Apply

The reforms take effect on 1 July 2027, but the cut-off date for determining which rules apply to your property was Budget night, 12 May 2026. Properties purchased before that date are grandfathered under existing arrangements. Properties purchased after are subject to the new framework, which limits negative gearing deductions to rental income or capital gains from residential property only, and replaces the 50% capital gains discount with inflation-based indexation and a minimum 30% tax on gains. New builds remain incentivised, with investors able to choose between the 50% discount or the new arrangements, whichever delivers the lower tax.

How Doncaster Investors Are Responding

Doncaster's proximity to the Eastern Freeway and Westfield shopping precinct has historically attracted owner-occupiers and investors alike. In the weeks following the Budget announcement, we saw a noticeable shift in investor enquiries. Those who had been waiting for the right property began moving more quickly, conscious that established properties purchased after Budget night would be subject to different tax treatment in just over 12 months.

Consider an investor who had been watching the Doncaster unit market for six months. They had narrowed their options to two properties: an established two-bedroom apartment near The Pines Shopping Centre and a newly completed unit in the same area. Before the Budget, the established property was the preferred option due to a lower purchase price. After the Budget, the new build became more attractive. Under the reforms, new builds allow the investor to retain either the 50% capital gains discount or choose inflation indexation, while the established property would be locked into the new arrangements from July 2027.

Negative Gearing Losses and Carry-Forward Provisions

From 1 July 2027, losses from established residential properties purchased after 12 May 2026 can only be offset against rental income or capital gains from residential property. If your investment property runs at a loss in a given year and you have no other residential property income to offset it against, that loss can be carried forward indefinitely to offset future residential property income. The deduction is deferred, not lost, but the immediate cash flow impact changes. Investors who rely on negative gearing to reduce their annual tax bill will need to factor in higher tax payments during the early years of ownership.

Interest Only Versus Principal and Interest Under the New Framework

Interest only loans remain a common structure for investment property finance, particularly where the investor wants to maximise tax deductions and preserve cash flow. Under the new negative gearing rules, the choice between interest only and principal and interest repayments carries additional weight. If your rental losses can only be offset against other residential property income, holding multiple properties becomes one way to maintain the tax benefit. An investor with two properties, one positively geared and one negatively geared, can still offset losses against the rental income from the positively geared asset.

In a scenario where a Doncaster investor purchases a new townhouse with an interest only investment loan, the full interest cost remains a claimable expense. If the property generates rental income of $28,000 per year and total expenses including interest, body corporate, and property management come to $35,000, the $7,000 shortfall can be carried forward if there is no other residential property income to offset it against. Switching to principal and interest repayments would increase the annual outlay but does not change the tax treatment of the loss, as principal repayments are not deductible.

Established Properties Purchased Before Budget Night

If you purchased an investment property in Doncaster or elsewhere before 12 May 2026, the capital gains tax discount and negative gearing rules remain unchanged. You retain the 50% discount on capital gains for assets held longer than 12 months, and rental losses continue to be deductible against all income sources, not just residential property income. This distinction creates a clear dividing line in the market. Properties purchased before that date carry a tax advantage that properties purchased afterwards do not, at least for investors subject to the new rules.

Refinancing and the Timing Question

If you are considering refinancing an existing investment property, the date you purchased the property determines which tax rules apply, not the date you refinance. Refinancing does not reset the clock or change your eligibility for the 50% capital gains discount or full negative gearing deductions. This is relevant for investors who secured their property before Budget night and are now reviewing their loan structure to access equity or secure a lower rate. The grandfathering provisions travel with the property, not the loan product.

For investors in Doncaster looking to leverage equity from an existing property to fund a second purchase, understanding your borrowing capacity under current lending conditions is essential. Lenders assess rental income at a discounted rate, typically 80%, and apply serviceability buffers when calculating how much you can borrow. If you are purchasing an established property after 12 May 2026, the lender's assessment does not change, but your after-tax cash flow position will once the reforms take effect in July 2027.

New Builds and the Investor Choice Provision

New builds purchased after Budget night allow investors to choose between the existing 50% capital gains discount or the new inflation-indexed framework, whichever results in a lower tax liability at the time of sale. This provision is designed to maintain investor interest in new housing stock. For investors focused on long-term capital growth in areas like Doncaster East, where new townhouse developments are being delivered near schools and parks, this flexibility provides a level of certainty that established properties no longer offer.

What This Means for Investors Planning Their Next Purchase

Timing now plays a more explicit role in shaping the long-term return from an investment property. Investors who secured established properties before Budget night retain access to the previous framework. Those purchasing after that date need to factor in deferred negative gearing benefits and a different capital gains calculation. New builds offer a middle ground, with the ability to choose the most favourable tax treatment at the time of sale. For Doncaster-based investors, working with a mortgage broker in Doncaster who understands both the lending landscape and the recent tax changes can clarify which option aligns with your long-term strategy.
