Important: Proposed legislation, not yet passed
The changes announced in the May 2026 Federal Budget are proposals subject to parliamentary legislation. They are not yet law. Investors should seek independent tax advice for their specific situation. This article reflects the government’s announced position as at June 2026.
The Big Picture
What Actually Changed on Budget Night
The 2026–27 Federal Budget announced two significant reforms that will reshape how residential property investment is taxed in Australia. Together they represent the most substantial change to property tax settings since the 50% CGT discount was introduced in 1999.
The two key changes are:
1. Negative gearing on established residential properties purchased after 7:30pm AEST on 12 May 2026 will be restricted from 1 July 2027.
2. The 50% CGT discount will be replaced by cost base indexation plus a 30% minimum tax on net capital gains from 1 July 2027.
What did not change: commercial property, tax depreciation deductions, and the main residence exemption are all unaffected.
Key Dates Every Investor Needs to Know
Properties under contract at or before this time are grandfathered. Existing owners and those who had already exchanged contracts retain full access to negative gearing and the 50% CGT discount under the old rules indefinitely.
Negative gearing restrictions apply to established residential properties bought after Budget night. The new CGT indexation regime and 30% minimum tax replaces the 50% discount. The new CGT rules only apply to gains accruing from this date, not to historical gains.
Investors with existing properties who are considering selling have a window to realise capital gains and be taxed under the current 50% discount regime. Pre-1985 assets remain CGT-exempt on gains up to this date.
These measures are not yet law. The legislation must pass both houses of parliament. Final rules, definitions, and transitional arrangements may differ from the announced position.

Negative Gearing: What Is Changing and What Is Not
|
Before Budget Night
Current Rules (Grandfathered)
Rental losses from established properties can be offset against all other income, including salary and wages. This reduces your taxable income and produces a tax saving each year the property is negatively geared. |
From 1 July 2027
New Rules (Established Properties Bought After Budget Night)
Rental losses can only be offset against rental income from other investment properties. Excess losses are quarantined and carried forward to future years or offset against capital gains when you sell. |
What this means in practice
If you buy an established residential property from 13 May 2026, and that property makes a rental loss of $15,000 in a year, you cannot use that loss to reduce your salary income. The loss carries forward. You will only benefit from it when you have sufficient rental income or when you sell the property.
Who Is Exempt from the Negative Gearing Changes
Change 2 of 2
Capital Gains Tax: The 50% Discount Is Being Replaced
From 1 July 2027, the 50% CGT discount that has applied since 1999 will be replaced for established properties with a cost base indexation model and a 30% minimum tax floor on net capital gains.
|
Old Method (Pre-1 July 2027 Gains)
50% CGT Discount
Hold the asset for more than 12 months and pay tax on only half the nominal gain. Simple, but does not account for inflation. Gains accrued before 1 July 2027 still attract the 50% discount. |
New Method (Post-1 July 2027 Gains)
CPI Indexation + 30% Minimum Tax
Your cost base is adjusted for inflation (CPI). Tax is paid only on the real gain above inflation. A 30% minimum tax applies on the indexed net gain. New builds can choose either method. |
The transitional split — how gains before and after 1 July 2027 are treated
If you already own a property, the 50% CGT discount continues to apply to gains accrued up to 30 June 2027. The value of your property at 1 July 2027 effectively becomes a new cost base for gains accruing from that date, which will be subject to the new indexation and minimum tax rules. You will not be hit with the new rules retroactively on the growth you have already achieved.
Real-World Scenarios: How the Numbers Change
Property bought in 2018 for $650,000. Value today: $1,100,000.
Nominal gain: $450,000. Under the current 50% discount, taxable gain is $225,000. At a 37% marginal rate, CGT payable is approximately $83,250.
Property value at 1 July 2027: $1,100,000. Sell in 2032 for $1,400,000.
Gain up to 30 June 2027 ($450,000) retains the 50% discount. Gain from 1 July 2027 ($300,000) is subject to indexation and the 30% minimum tax. CPI indexation reduces the taxable portion of the post-2027 gain.
Investor buys a new apartment for $750,000 after 12 May 2026.
Retains full negative gearing access during ownership. At sale, can choose either the 50% CGT discount or the new indexation method, whichever produces the better tax outcome.
Tax Depreciation: More Important Than Ever
Tax depreciation deductions are unaffected by the budget changes. For investors with restricted negative gearing, a depreciation schedule helps maximise allowable deductions within the new quarantine system. For CGT purposes, your depreciation records directly affect your cost base calculation — which under the new indexation method becomes even more critical to get right.

Silver Lining
Commercial Property: An Increasingly Attractive Alternative
The budget changes apply only to established residential property. Commercial property retains all existing tax settings, including full negative gearing, the current CGT discount, and complete deductibility of outgoings and depreciation against all income sources.
Koste’s view
The budget changes make commercial property relatively more attractive on a tax-adjusted basis. Higher yields, tenant-paid outgoings, longer leases, and fully retained negative gearing create a compelling comparison. Depreciation deductions on commercial property are often significantly higher than residential, particularly for properties with substantial plant and equipment.
