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.

Investors in SMSFs considering property should cross‑check this with [SMSF Property After the Budget: Buy, Hold or Sit Tight?].

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.

If that’s you, read the one‑week action plan in [Mum-and-dad investors: how to protect your plan under new rules] – it dovetails directly with the ideas in this article.

4. Negative gearing meets the new CGT world

Negative gearing has always been a front‑end / back‑end story:

• Front‑end: rental losses reduce tax while you hold the property.
• Back‑end: the 50% CGT discount softened the tax hit when you eventually sold.

The 2026–27 reforms reshape both ends.

4.1 CGT changes that matter for geared investors

From 1 July 2027 (subject to final law):

• The 50% CGT discount disappears for most individuals and trusts.
• Instead, your cost base is indexed for inflation using CPI, so you pay tax on real (inflation‑adjusted) gains.
• A minimum 30% tax generally applies to capital gains for Australian residents.

So your combined tax outcome becomes:

• Less tax relief from negative gearing along the way (for many newer established properties); and
• Potentially more tax on real capital gains at exit, relative to the old 50% discount world, especially if your marginal rate is well above 30%.

4.2 Why “grandfathered” doesn’t mean “set and forget”

Even if your existing property is grandfathered for negative gearing, you still need to:

• Track gains in two tranches – pre‑1 July 2027 and post‑1 July 2027.
• Keep meticulous records of cost base, improvements and holding costs.
• Re‑think whether holding very long term still makes sense under the new CGT minimum tax.

Pre‑retirees should pair this with [Smart moves for pre‑retiree property investors under new tax rules] to test whether paying down debt, rebalancing, or selling is now the better move.

5. What still works with negative gearing – and what doesn’t

Here’s a quick comparison of where negative gearing retains value and where it’s fading.

The unifying idea: negative gearing should be a side‑effect of a solid investment, not the main attraction.

6. Loan structuring: where negative gearing still interacts with borrowing

Even if the tax benefits shrink, the way your property is geared still has massive practical consequences.

6.1 Separate good debt and bad debt

For most households:

• Non‑deductible debt (your home loan, personal loans, credit cards) is the enemy.
• Deductible investment debt is not automatically good, but it’s usually less bad than non‑deductible debt at the same interest rate.

Under the new rules, it’s even more important to:

• Keep home and investment loans separate.
• Use offset accounts rather than redraw for flexibility.
• Avoid mixing purposes on a single loan.

The article [How to Restructure Property Loans Before Negative Gearing Shrinks] walks through how to clean this up before 1 July 2027.

6.2 Lenders don’t see negative gearing like the ATO does

Lenders already shade or ignore some tax benefits of negative gearing when calculating your borrowing power. After the reforms, expect them to:

• Assume less tax relief on rental losses;
• Apply higher buffers (APRA’s serviceability buffer is typically 3 percentage points above the actual rate); and
• Scrutinise living expenses and other debts more closely.

If you’re a business owner or have dividends/other investments, also read [How Negative Gearing, Dividends and Business Income Shape Your Loans] to understand how your tax strategy plays with your borrowing capacity.

6.3 Self‑employed investors: no more “tax clever but cash poor”

Self‑employed and small business clients often run:

• Lean taxable income for a few years; then
• A strong year when business profits jump or an asset is sold.

With negative gearing benefits shrinking and CGT minimums rising, you can’t afford to be:

• Tax‑efficient on paper but struggling to cover loan repayments in real life.

Pair your accountant and broker (or pick one who is both) to stress‑test your worst‑case years. The strategy guide for complex income [Property strategy for self‑employed and high‑income investors after tax shifts] takes you through this in more detail.

Re-running cashflow without generous negative gearing is essential before the new rules start.

7. One‑week action plan: what to do this week

You don’t need to panic‑sell or rush into an off‑the‑plan contract. You do need to get organised.

Step 1 – Map every property into the right “bucket”

Create a quick table for each property:

• Acquisition date.
• New build vs established; if new build, why you think it qualifies.
• Ownership structure (personal, joint, company, trust, SMSF).
• Estimated loan balance and interest rate.
• Current annual rent and key expenses.

Then tag each asset:

• Bucket 1 – Grandfathered (pre‑12 May 2026, or clearly protected under the rules).
• Bucket 2 – Post‑12 May 2026 established.
• Bucket 3 – New build / carve‑out (subject to final regulations).

Step 2 – Re‑run cashflow with no wage‑based negative gearing

For each property, run a conservative scenario:

1. Calculate annual net cashflow before tax (rent minus all costs, including interest and a maintenance allowance).
2. Assume no tax refund from negative gearing in the early years.
3. Check:
   • Can you cover that shortfall comfortably from your existing income?
   • What happens if rates rise another 1–2%?

If the answer is “only just” or “not really”, you need to act.

Step 3 – Tidy loan structures and buffers

Still before 1 July 2027 where possible:

• Separate home and investment debt.
• Consider splitting loans to lock in part of the rate and keep part variable (for flexibility).
• Build at least 3–6 months of expenses in accessible offsets.

This is especially urgent for properties in Bucket 2, where future tax relief on losses is weakest.

Step 4 – Decide: hold, deleverage, or reshape your portfolio

For each property, you’re weighing up:

• Hold and deleverage – keep the asset, pay down non‑deductible debt faster, gradually move to positive cashflow.
• Reshape – sell a marginal property, improve overall LVR, or pivot to a better located asset or different structure.
• Pause – if you’re in the middle of life or business changes, it may be smarter to stabilise and wait for more regulatory clarity.

Your decision should turn on asset quality, cashflow resilience and life goals, not just tax.

Decisions to hold, deleverage or reshape your portfolio should be based on asset quality and cashflow, not just tax deductions.

8. Who might still use negative gearing – and how

Even after the reforms, negative gearing still has a role, but it’s narrower and more deliberate.

8.1 Long‑term growth buyers

For investors targeting long‑term capital growth in quality locations:

• Mild negative gearing early on may still be acceptable.
• The plan should be that rents and incomes grow so the property becomes neutrally or positively geared in a reasonable timeframe.

8.2 Strategic use in structures

Some structures still allow more flexible use of losses and gains, particularly where:

• Losses can be applied against other investment income; or
• There’s a clear plan to stream future positive income to lower‑rate beneficiaries.

But remember: the post‑2026 rules for discretionary trusts also move towards quarantining residential rental losses within the trust, pushing your focus toward long‑term income and capital gains rather than early‑year loss distribution.

8.3 Not a rescue tool for marginal deals

The days of:

“It’s massively cashflow‑negative, but the tax refund will sort it”

are effectively over for many new established property purchases.

If a property only looks acceptable because of a big projected tax offset, treat that as a red flag and walk away or renegotiate.

9. Common traps to avoid under the new rules

A few mistakes we’re already seeing in conversations with investors:

9.1 Assuming “new build” status you may not have

Definitions of “new residential dwelling” will likely be technical:

• Off‑the‑plan purchases may qualify only if certain conditions are met.
• Renovated properties may not qualify if they don’t meet particular thresholds.

Until regulations are final, don’t buy purely on the promise of “tax‑advantaged” status.

9.2 Ignoring CGT changes when modelling returns

Many spreadsheets still assume a 50% CGT discount and current CGT rules. Under the new settings:

• You should model gains in pre‑ and post‑1 July 2027 tranches; and
• Use a minimum 30% tax rate on real gains as a base case.

As a rule of thumb when stress‑testing portfolios, halving today’s combined benefits from negative gearing and CGT discounts is a useful conservative starting point.

9.3 Mixing borrowing for home and investment

With more complex rules, sloppy loan structuring becomes extra painful. Avoid:

• Redrawing from your home loan for investment without a clear split;
• Using one big mixed‑purpose loan;
• Losing track of what each loan or split funded.

Deductibility follows purpose of the borrowing, not whose name is on the title. Mixing purposes makes it harder to claim correctly and respond to future rule changes.

10. How to get decision‑grade advice without analysis paralysis

You don’t need a 50‑page report to decide what to do this week. You do need someone who can see:

• The tax angle (negative gearing, CGT, trust rules);
• The borrowing angle (serviceability, buffers, APRA rules); and
• Your life goals (kids, business, retirement, lifestyle).

That’s why we lean on a triple‑credential view – CPA, tax agent and mortgage broker in one conversation – so you don’t get tax advice that wrecks your borrowing, or loan advice that ignores the 2026–27 Budget.

Use this simple script when you sit down with an adviser:

1. “Which bucket is each of my properties in under the new rules?”
2. “What’s my real after‑tax, after‑interest cashflow if negative gearing benefits halve?”
3. “If I do nothing until 2028, what’s my worst‑case scenario?”
4. “What are my two or three best options to stabilise and move forward?”

Key takeaways

• Negative gearing still exists, but the big benefits are narrowed to grandfathered holdings and qualifying new builds.
• For many established properties bought after 12 May 2026, rental losses will be quarantined, so you can’t rely on big tax refunds.
• CGT reforms from 1 July 2027 remove the 50% discount and introduce a 30% minimum tax on real gains, cutting total tax advantages from gearing.
• The new rules favour investors who focus on asset quality, sensible LVRs and cashflow resilience, not tax plays.
• This year is the time to map your properties, re‑run cashflow, clean up loans and buffers, and decide whether to hold, deleverage or reshape your portfolio.
