Negative Gearing and CGT Overhaul: What Every Mortgage Broker Needs to Know Now

The 2026-27 Budget rewrites the investor playbook. Here is what changed, what it means for your pipeline, and how to turn disruption into opportunity.

Key Takeaways

• Negative gearing for established residential properties is abolished for purchases after 7:30pm on 12 May 2026, effective 1 July 2027.
• Rental losses can only be offset against rental income or future capital gains — not salary or personal income.
• New builds remain fully eligible for negative gearing, creating a clear policy incentive for construction lending.
• The 50% CGT discount is replaced by cost base indexation and a 30% minimum tax rate on gains for assets held 12+ months.
• Major lenders have already reduced max LVRs for property investors by approximately 20%.
• Brokers must adapt their investor pipelines, lender panel knowledge, and BID documentation to remain competitive.

On 12 May 2026, the Federal Government delivered the most significant change to property investment taxation in a generation. As part of the 2026-27 Budget, Treasurer Jim Chalmers announced the abolition of negative gearing for established residential properties purchased after 7:30pm on Budget night, alongside a fundamental restructure of the capital gains tax discount. For mortgage brokers, these reforms do not just change the tax landscape — they reshape the entire investor lending pipeline.

This is not a theoretical policy debate anymore. Lenders have already responded. LVRs are tightening. Investor product pricing is shifting. And your clients are asking questions — some panicked, some confused, most unsure what to do next. The brokers who understand these reforms deeply, and can translate them into clear guidance, will be the ones who retain and grow their investor books. Those who wait will lose clients to advisers who moved first.

What Changed on Budget Night

The 2026-27 Budget introduced two interconnected reforms targeting residential property investors:

1. Negative gearing restrictions. From 1 July 2027, investors who purchase established residential properties after 7:30pm on 12 May 2026 will no longer be able to offset rental losses against their salary, wages, or other personal income. Rental losses will be “ring-fenced” — deductible only against other residential rental income or carried forward to offset future capital gains from the same asset class.

2. Capital gains tax restructure. The existing 50% CGT discount for assets held longer than 12 months will be replaced with a cost base indexation method. Additionally, a 30% minimum tax rate will apply to capital gains on qualifying assets. These CGT changes apply only to gains accruing after 1 July 2027.

How Negative Gearing Restrictions Work

Under the old rules, an investor earning $120,000 in salary who held a rental property generating a $15,000 net loss could offset that loss against their salary income, reducing their taxable income to $105,000. That mechanism — the ability to use property losses to reduce tax on unrelated income — has been a cornerstone of Australian property investment strategy for decades.

Under the new rules, that same $15,000 loss can only be offset against rental income from other residential investment properties. If the investor has no other rental income, the loss is carried forward indefinitely and can be used to reduce future rental income or offset capital gains when the property is eventually sold.

For brokers, the practical impact is immediate. Many investor clients have been structuring their borrowing on the assumption that negative gearing benefits would subsidise holding costs, effectively improving their cash flow position. Without that subsidy, the after-tax holding cost of an established investment property increases materially. That changes servicing calculations, deposit requirements, and the overall borrowing profile.

Lenders will assess these borrowers differently. Some already are. The conversation you have with an investor client in July 2026 is fundamentally different from the one you had in April.

The CGT Overhaul Explained

The CGT changes are equally significant, though more nuanced. Under the existing system, an investor who held a property for more than 12 months received a flat 50% discount on the capital gain. So a $200,000 gain would be taxed as if it were $100,000, then added to the investor’s marginal income.

The new system replaces that discount with two mechanisms. First, cost base indexation: the property’s original purchase price is indexed to inflation, so the taxable gain reflects real (inflation-adjusted) growth rather than nominal growth. Second, a 30% minimum tax rate applies to capital gains on qualifying assets held for 12 months or longer. For high-income investors who would otherwise pay at the 45% or 47% marginal rate, this minimum rate is actually more favourable than a flat 50% discount in many scenarios. For investors on lower marginal rates, the outcome may be less favourable.

The critical detail for brokers: these CGT reforms apply only to gains accruing after 1 July 2027. Gains accumulated before that date are treated under the existing rules. This means the transition is not a cliff edge — it is a blended calculation that will require careful tax planning.

Lender Response: Lower LVRs and Tighter Policy

The lending market has not waited for the legislation to pass. Within weeks of the Budget announcement, major lenders began adjusting their investor lending policies. The most visible change: maximum loan-to-value ratios for investment property purchases have been reduced by approximately 20 percentage points across several major banks.

Where an investor might previously have borrowed at 90% LVR with lenders mortgage insurance, many lenders are now capping investment LVRs at 70% or 75% for established property purchases. This is partly a risk-pricing response — without negative gearing benefits, the cash flow profile of investor borrowers looks weaker — and partly an anticipation of APRA’s likely response.

APRA has not yet issued new macroprudential guidance specifically targeting the post-reform environment, but the regulator’s track record suggests it will act if investor lending risk concentrations emerge. Brokers should monitor APRA announcements closely and be prepared for further tightening.

For brokers, this means three things. First, investor clients need larger deposits. Second, lender selection becomes more critical — not all lenders are applying the same policy changes at the same pace. Third, the gap between lenders offering competitive investor terms and those retreating from the segment is widening, creating opportunities for brokers with strong panel knowledge.

The New-Build Opportunity

The most significant strategic implication of these reforms is the deliberate policy incentive toward new-build investment. By preserving negative gearing exclusively for new residential construction, the government has created a clear two-tier investment landscape.

For brokers, this is where the opportunity lies. The investor client who was planning to buy a second-hand apartment in an established suburb now has a genuine tax incentive to consider a house-and-land package, an off-the-plan apartment in a new development, or a knock-down-rebuild project. These are structurally different deals with different lender requirements, different risk profiles, and different commission structures.

Brokers who develop expertise in construction lending, house-and-land packages, and new-build finance products will be positioned to capture a growing share of investor business. This means understanding progress payment structures, construction loan drawdown processes, builder requirements, and the lenders who are leaning into this segment.

It also means building referral relationships with developers, project marketers, and builders — a channel that many brokers have historically underweighted. Those referral pipelines are about to become significantly more valuable.

Client Conversations: What to Say and When

The most immediate pressure most brokers will feel is in client conversations. Investor clients are already reading headlines and drawing conclusions — some accurate, many not. Your role is to provide clarity without crossing into tax advice territory.

For clients with existing investment properties: Reassure them. Their current arrangements are grandfathered. Negative gearing continues for properties held before Budget night. The CGT changes affect only gains accruing after 1 July 2027, and the blended calculation means the transition is gradual. Encourage them to speak with their accountant about the long-term impact, particularly around disposal timing.

For clients planning to buy established investment properties: Be direct. The tax benefit structure has changed. Walk them through the cash flow impact of ring-fenced losses. Explain that lenders are tightening LVRs, which means larger deposits. Recommend they model the investment with and without negative gearing benefits, and suggest they explore new-build alternatives.

For clients open to new-build investment: This is your opportunity. Explain that new builds retain full negative gearing eligibility. Walk them through the construction lending process. Position yourself as the broker who can navigate the different product structures and lender requirements. If you have developer or builder referral partners, introduce them.

In all conversations, document your recommendations thoroughly. Under ASIC’s Best Interest Duty, you must demonstrate that your recommendation considered the client’s full circumstances, including the tax implications of their purchase decision. You do not need to provide tax advice, but you do need to show that you flagged the issue and recommended appropriate specialist advice.

Best Interest Duty and Compliance Implications

The negative gearing and CGT reforms create new compliance considerations under the Best Interest Duty framework. ASIC expects brokers to act in the best interests of their clients, and that obligation extends to being aware of material factors that could affect the suitability of a credit product recommendation.

Tax changes of this magnitude are clearly material. If a client is borrowing to purchase an established investment property after Budget night, the broker should, at minimum:

• Acknowledge in file notes that negative gearing is no longer available for the property being purchased
• Note that the client’s after-tax holding costs may be higher than they anticipate
• Record that the client was advised to seek tax advice regarding the investment structure
• Document the rationale for the loan structure and lender selection, including any LVR constraints
• If a new-build alternative was discussed, note the outcome of that conversation

This is not about adding bureaucracy. It is about protecting your clients, your licence, and your business. In an enforcement environment where ASIC is actively reviewing broker file quality, demonstrating that you understood and addressed these changes is a baseline expectation.

Broker Action Plan: Repositioning for the New Landscape

The brokers who will come out of this transition stronger are the ones who act now, not after 1 July 2027. Here is a practical framework for repositioning your investor business:

1. Audit your investor pipeline.

Review every active investor enquiry. Identify which clients are considering established properties and which could be redirected toward new builds. For clients who exchanged contracts before Budget night, confirm their grandfathered status and ensure documentation is in order.

2. Update your product knowledge.

If construction lending is not your strength, now is the time to upskill. Understand progress payment structures, fixed-price building contracts, council approval timelines, and the differences between construction loans and standard investment loans. Your aggregator likely has training resources — use them.

3. Build new referral channels.

Connect with developers, project marketers, and builders in your area. Attend industry events, join property development forums, and position yourself as the broker who understands new-build finance. These relationships will generate a steady flow of investor clients who are actively looking for the tax advantages that new builds now exclusively offer.

4. Strengthen your tax adviser network.

You will be referring more clients to accountants and tax advisers over the coming months. Make sure you have trusted referral partners who understand property investment taxation. A two-way referral arrangement with a proactive accountant can be one of the most valuable partnerships in your business.

5. Refresh your marketing and content.

Your website, social media, and client communications should reflect the new landscape. Create educational content explaining the changes. Position yourself as the broker who is across the detail. Investor clients are actively looking for guidance right now — be the voice they trust.

The Bottom Line

The negative gearing and CGT reforms announced in the 2026-27 Budget are the most significant structural changes to property investment taxation in decades. For mortgage brokers, they represent both a challenge and a clear opportunity.

The challenge is real: established investor lending volumes will likely contract, clients will need more guidance, and compliance expectations will increase. But the opportunity is equally clear. The shift toward new-build investment creates demand for construction lending expertise, opens new referral channels, and rewards brokers who can navigate complexity on behalf of their clients.

Your investor clients are not disappearing. They are looking for a new path. Be the broker who shows them one.
