Established Properties and Negative Gearing After 1 July 2027: Everything Landlords Need to Know

Introduction

Most residential investment property in Australia is established stock existing houses and apartments that have been owned and occupied before. Under the 2026-27 Budget reform, this is the category most affected by the new negative gearing rules. From 1 July 2027, established property losses can no longer be offset against wage income. But the impact, while real, is materially smaller than many headlines have suggested.

Treasury's own worked example known as the Yoonseo example shows that an investor buying a $519K established property after the announcement pays only $186 more total tax over 10 years compared with the old rules. The reason: losses are deferred, not eliminated. Carry-forward losses preserve the tax value of deductions; they just delay it until you have offsetting residential property income.

What Counts as Established Property

An "established" property for the purposes of the reform is any residential property that does not qualify as a new build. This includes:

• Any house, apartment, townhouse, or unit previously owned by an owner-occupier or investor
• Newly-built properties that have been occupied for more than 12 months before first investor sale
• Resold "new" apartments second-hand purchases from another investor (not from the developer)
• KDR projects that replace a single dwelling with a single dwelling (no supply increase)

For the new build categories that retain full negative gearing, see new build rules.

The Two Affected Cohorts

Cohort A: Transitional (acquired 13 May 2026 – 30 June 2027)

If you buy an established property between the budget announcement and 30 June 2027, you can claim negative gearing against wages only until 30 June 2027. Losses from any subsequent income year convert to carry-forward.

The transitional period is essentially a brief window of preserved deductibility. For purchases in late 2026 or early 2027, the wage-offset period may be only a few months and is determined by the income year, not the holding period.

Cohort B: Post-commencement (acquired on or after 1 July 2027)

If you buy an established property on or after 1 July 2027, you cannot offset any net rental losses against wage income at any time. All losses are carry-forward from inception.

How Carry-Forward Losses Work

Carry-forward losses are the central mechanism preserving the long-term tax value of negative gearing under the new rules. The mechanics are straightforward:

1. Calculate your net rental loss for the income year using normal deductibility rules.
2. The loss is added to your "residential property loss balance" your accumulated carry-forward.
3. In future years, the carry-forward balance can be applied against:
   • Net rental income from any residential investment property you hold
   • Capital gains on disposal of any residential investment property
4. Unused carry-forward losses persist indefinitely until used.

For full detail on the carry-forward mechanics, see carry-forward losses explained.

Yoonseo Example: $186 Extra Tax Over 10 Years

The budget papers worked through a representative example to demonstrate the modest impact of the reform on a typical investor. Yoonseo is a wage-earning Australian who buys her first investment property after the budget announcement.

• Property: $519,000 established apartment
• Acquisition: After 12 May 2026
• Holding period: 10 years
• Accumulated carry-forward losses over 10 years: $22,879
• Carry-forward losses applied against capital gain on disposal

The total tax difference for Yoonseo across 10 years is approximately $186 well under $20 per year. The reform defers tax benefits but preserves them; the ultimate cost to the investor is essentially the time value of money on deferred deductions, not the loss of deductions themselves.

Why the Impact Is Smaller Than Headlines Suggest

The post-July 2027 rules quarantine residential property losses to residential property income. This means:

• Net rental income from other residential investment properties you own can absorb the losses.
• The capital gain on sale of any residential investment property can absorb the losses.
• Losses persist indefinitely they cannot expire.

Across a typical investor's full property cycle (10-15 years of holding, then sale), the carry-forward losses are almost always fully utilised against the eventual capital gain. The deduction is deferred, but not lost.

The exception is investors who never sell the carry-forward losses remain unused unless other residential property income absorbs them. For most investors, this is not a realistic scenario; property is generally either sold during the investor's lifetime or on estate disposal.

Decision Framework: Established vs New Build

For investors making a fresh acquisition post-1 July 2027, the comparison between established property and new build can be framed as follows:

• New build advantage: Immediate wage-offset of losses (cash flow benefit in early years).
• Established advantage: Often better-located stock, more renovation upside, more flexible exit options.

The Yoonseo example shows the after-tax cost of established property over 10 years is only $186 higher. That is small relative to the variation in property selection getting the suburb right, the price right, and the property right matters far more than the marginal tax difference.
