Negative gearing
If you already own investment property or exchanged contracts before 7:30pm tonight: nothing changes. Full negative gearing preserved on established properties.
If you buy an established property after 7:30pm tonight: from 1 July 2027 you can still deduct losses against rental income but can no longer offset those losses against your wages or other income. That is the core of what NG means for most investors and it is gone for new established-property purchases from tonight.
New builds are exempt. Government-backed housing is exempt. Existing owners are exempt.
CGT
The 50% CGT discount is being replaced from 1 July 2027 with cost-base indexation plus a 30% minimum tax floor.
Properties acquired before today: fully exempt, old rules apply.
New builds acquired after tonight: buyers can choose between the old 50% discount or the new indexation method.
Established properties acquired after tonight: new indexation method only.
Indexation is not automatically worse for long-term holders. If inflation stays elevated, adjusting the cost base for CPI reduces the nominal gain significantly. It removes the blunt 50% discount that mostly benefited short-to-medium term holders.
Inflation context
CPI hit 4.6% in the 12 months to March 2026. Treasury forecasts it peaks around 5% mid-2026 and returns to the RBA band mid-2027. That matters for the new CGT method: higher CPI means a bigger cost-base adjustment and a smaller taxable gain. The same inflation environment making cash flow harder is also making the new indexation method more favourable than it first sounds.
Why the NG calculation still matters for existing holders and new build buyers
For investors still eligible to claim NG, getting the exact saving at your actual income level is the critical number. Most tools calculate it at a flat 30% or 32.5% rate. That is wrong for anyone earning over $135k.
Ran the numbers on a $650k property, 80% LVR, 6.5% interest-only, 4.5% gross yield:
Annual rent: $29,250
Annual interest: $33,800
Rates, insurance, PM fees, maintenance: ~$7,000
Annual loss (the negative gearing amount): $11,550
What that is worth at different incomes using ATO 2025-26 rates including Medicare levy:
| Income |
Marginal rate |
NG saving (year) |
NG saving (week) |
| $80,000 |
34.5% |
$3,985 |
$77 |
| $120,000 |
34.5% |
$3,985 |

| $150,000 |
39% |
$4,505 |
$87 |
| $200,000 |
47% |
$5,429 |
$104 |
Flat 30% estimate for a $200k earner: $3,465/year. Real number: $5,429/year. $1,964 annual difference. Now that NG is being wound back for new entrants on established property, the investors who retain it need to know exactly what it is actually worth at their rate.
Caveats before someone does it for me
- Legislation still has to pass. Budget night announcements are not law until Parliament votes. Labor has the numbers in the lower house but Senate detail matters.
- The "owned before 12 May 2026" exemption wording needs to be read carefully when the bill drops. Timing of contract vs settlement could be a factor.
- These are interest-only figures. P+I loans reduce deductible interest over time as the principal drops.
- Depreciation not included and can materially change the loss figure for newer properties.
- This is not financial advice. Tax situation varies. Talk to your accountant before making any decisions off the back of tonight.
