Negative Gearing After the Latest Budget: What Actually Changes

The latest Budget does not abolish negative gearing across the board. It creates a split system: (1) properties you owned before 7:30pm AEST on 12 May 2026 keep the current rules; (2) most qualifying new builds will still allow negative gearing plus the 50% CGT discount; and (3) established properties bought after that time lose wage-offset negative gearing from 1 July 2027, with rental losses quarantined.

In other words: if you already own a rental, you’re mostly grandfathered. The real change is for future established property purchases and how aggressively you can gear them.

Three property buckets now determine how negative gearing applies after the latest Budget.

1. The new negative gearing landscape in plain English

1.1 The three property buckets that now matter

From the 2026–27 Budget and the Tax Reform Bill 2026, residential investments now sit in three practical buckets (see also /insights/negative-vs-positive-gearing-long-term-wealth-australia):

Commercial property and some institutional structures appear largely outside these negative gearing changes, based on current guidance.

1.2 What “loss quarantining” actually means

A quarantined loss is still a loss, just not one you can use against your salary.

• If your new established investment property loses $8,000 a year after 1 July 2027, that loss cannot reduce your PAYG tax.
• Instead, the $8,000 sits in a rental loss bucket and can only offset future rental income or future capital gains from residential property.

So you still carry the loss for tax, but you must fund the cash shortfall out of pocket in the meantime.

2. What stays the same – and for whom

2.1 Grandfathered properties

Residential properties held before 7:30pm AEST on 12 May 2026 are generally grandfathered.

• You can keep offsetting net rental losses against salary and other income under existing negative gearing rules.
• This continues until you sell. The next owner falls under the new regime.

For many mum-and-dad investors with 1–3 properties, this means the current portfolio is largely unchanged tax-wise, but future acquisitions are not.

2.2 New builds as the big carve‑out

Budget documents and the Tax Reform Bill indicate that:

1. Eligible new build residential investments will continue to access negative gearing; and
2. They will also keep the 50% CGT discount, even as other assets move to an indexation/minimum-tax model.

The catch: exactly what counts as a “new residential dwelling” is partly deferred to later regulations. Off‑the‑plan with prior occupancy, major renovations, and dual‑occupancy conversions may sit in grey zones. Until the final definitions land, treat new‑build status as a bonus, not a guarantee.

For strategy, that means you should still model zero negative gearing benefit first, then add any new-build concession as upside.
