Negative gearing after the Budget: practical rules investors must know

Negative gearing is not dead after the 2026–27 Federal Budget, but it is no longer a simple “buy, lose money now, claim it back at tax time” play.

Under the Treasury Laws Amendment (Tax Reform No. 1) Bill 2026, much of the traditional tax benefit from negative gearing will be restricted for newer established residential properties from 1 July 2027, while older and qualifying new‑build investments stay under more generous rules. To make a sound decision this week, you need to know exactly which bucket each property falls into, how rental losses will be treated, and how this lines up with the new capital gains tax settings.

This guide gives you a decision‑grade map: what still works, what doesn’t, and what to do before the new rules bite.

1. Quick explainer: what’s actually changing with negative gearing?

Negative gearing is when your deductible property expenses (interest, rates, insurance, repairs, depreciation, agent fees) are higher than your rental income, creating a rental loss for tax purposes.

Historically, investors could:

1. Offset those rental losses against salary, business or other income; and
2. Later pay capital gains tax on eventual profits, often after a 50% CGT discount if the asset was held for at least 12 months.

From 1 July 2027, under the 2026–27 Budget reforms:

• Many residential rental losses will be quarantined to the property or portfolio instead of being used against your wage or business income.
• The 50% CGT discount is removed for individuals and most trusts, replaced by CPI indexation and a minimum 30% tax on capital gains in most cases.
• Grandfathering and exemptions mean some properties keep more generous treatment, especially older holdings and qualifying new builds.

The key message: you can still deduct genuine rental expenses, but the timing and value of those deductions are changing.

2. The three big buckets: what’s grandfathered, what’s restricted

The Budget and the Reform Bill split residential property into three practical buckets.

2.1 Bucket 1 – Grandfathered existing investments

These are generally:

• Residential properties acquired before 12 May 2026; and
• Certain post‑2026 investments that clearly meet “new residential dwelling” definitions once final rules are settled.

Indicatively, for Bucket 1 properties:

• Rental losses remain fully offsettable against your other income, subject to normal rules.
• You’re still caught by the new CGT regime from 1 July 2027 – so the 50% discount disappears for gains accruing after that date, replaced by CPI indexation and a 30% minimum tax on the real gain.

So negative gearing works here much like it used to from a cashflow point of view, but your back‑end CGT outcome changes.

2.2 Bucket 2 – Established properties bought after 12 May 2026

This is the problem zone Treasury is targeting.

• Residential investments in existing dwellings acquired on or after 12 May 2026, that do not qualify as “new builds”, will see rental losses heavily restricted from 1 July 2027.
• Details are in draft and may shift, but the direction is clear: early‑year negative cashflow will no longer be a powerful tax shield for wage earners.

Practically, this means:

• You’ll still claim rental deductions; however
• Losses may be quarantined to future rental income or capital gains, not used to reduce your salary or business income in the year incurred.

Your after‑tax cashflow could be thousands of dollars worse each year than under the old rules.

2.3 Bucket 3 – New builds and carve‑out assets

Budget papers and the Reform Bill flag protection or better treatment for:

• Qualifying new residential dwellings (definitions to come in regulations);
• Widely held structures such as large listed or wholesale investment vehicles;
• Super funds (including SMSFs) and certain housing programs.

For these, the policy intent is to:

• Keep or partially retain negative gearing benefits as an incentive to support new housing supply; and
• Continue allowing super funds to deduct interest and other costs according to existing principles.

Different property ‘buckets’ now attract very different negative gearing outcomes.

3. How the new rental loss rules hit real cashflow

To see what still works, you need to compare the old and new cashflow mechanics.

3.1 Old world vs new world – worked example

Assume:

• Investment loan: $700,000 interest‑only at 6.0% p.a. (illustrative only)
• Annual interest: $42,000
• Rent: $650/week = $33,800/year
• Other deductible costs (rates, insurance, maintenance, management): $6,000/year
• Net rental loss: $42,000 + $6,000 − $33,800 = $14,200
• Investor’s marginal tax rate: 39% (including Medicare)

Old world (full negative gearing):

• Tax saving from loss = 39% × $14,200 ≈ $5,538
• After‑tax cashflow shortfall = $14,200 − $5,538 ≈ $8,662/year (~$167/week)

New world (loss quarantined):

• You still record a $14,200 tax loss, but it’s trapped against future rental profits or capital gains.
• No current‑year refund from your wage.
• After‑tax cashflow shortfall ≈ the full $14,200/year (~$273/week) until you have positive rental income or a taxable gain to soak it up.

The tax benefit isn’t gone forever, but it’s pushed into the future, which can strain your household budget right now.

3.2 Who gets hit hardest?

The impact will feel sharpest for:

• Mum‑and‑dad investors with 1–3 properties who’ve relied on refunds to plug cashflow gaps.
• Younger professionals with high incomes and aggressive LVRs.
• Self‑employed and business owners already juggling lumpy cashflow.
