The 2026–27 Australian Federal Budget has introduced a series of significant reforms concerning housing supply and property taxation. Among these, the most notable adjustments are to Negative Gearing and Capital Gains Tax (CGT). The government's core objective is to redirect funds from "purchasing existing homes" to "building new housing supply" through tax policies and infrastructure investment.

While these measures are currently budget proposals and have not yet completed the legislative process, their policy direction is already very clear. For borrowers, this not only impacts future tax arrangements but could also affect borrowing capacity, loan structure, and overall investment strategies.

Why is the Federal Government driving this reform?

Insufficient housing supply is the core issue

In recent years, Australia's population has continued to grow, but the pace of new home construction has not kept up with demand. High building costs, labour shortages, and lengthy approval processes have consistently constrained housing supply, driving up property prices and rents.

Government aims to redirect investment towards new home construction

The primary logic behind this budget proposal is not to "suppress property investment," but rather to shift capital towards increasing new housing supply by altering tax incentive structures. Specific measures include:

1. Restricting negative gearing benefits for newly purchased existing investment properties;
2. Adjusting the Capital Gains Tax calculation method;
3. Committing AUD 2 billion for housing infrastructure;
4. Accelerating planning approval processes.

Potential impact on first-home buyers and the overall market

Should investor interest in existing properties decline, first-home buyers might face less competition in established communities. Concurrently, increased infrastructure investment and planning reforms are expected to boost housing supply in the medium to long term.

How will Negative Gearing and CGT reforms change lending and investment logic?

Negative gearing for existing investment properties isn't completely abolished, but deferred

Many media outlets mistakenly interpret "no negative gearing" as "tax benefits completely disappearing," but economically, this isn't the case.

If an existing investment property purchased in the future incurs losses during its initial holding period, these losses may not be immediately deductible against salary income. However, they can typically be carried forward to offset future positive rental income or other related gains from that property.

This means:

1. Tax benefits have not entirely vanished;
2. They've merely shifted from "immediate tax refunds" to "gradual future utilisation";
3. The biggest impact will be on cash flow during the holding period.

Why might this impact borrowing capacity?

In some banks' loan assessments, the anticipated tax refunds from negative gearing are sometimes included in cash flow analysis.

If existing investment properties lose immediate negative gearing:

1. Annual tax refunds will decrease;
2. After-tax cash flow will decline;
3. Disposable income will be reduced;
4. The maximum borrowing capacity for some borrowers may decrease.

This impact is typically more pronounced for high-income professionals.

CGT reforms reduce the attractiveness of short-term gains

The budget proposes that from 1 July 2027, the current 50% CGT discount will be replaced by an inflation-adjusted model, with a minimum tax rate floor of 30%.

This means:

1. After-tax returns for strategies reliant on short-term capital appreciation may decrease;
2. Investment decisions will increasingly depend on long-term cash flow and asset quality;
3. The "buy-hold for a few years-sell for profit" model will require re-evaluation.

Investors may need to re-evaluate investment property types and loan structures

Under the new policy framework, investors may need to conduct a more comprehensive assessment than before when choosing property types and loan structures.

If seeking to retain immediate negative gearing benefits, new property investment may become more important

According to the budget proposals, only newly constructed residential properties are expected to continue enjoying more comprehensive negative gearing treatment and more favourable Capital Gains Tax arrangements in the future.

This means the following types of investment projects may receive more attention:

1. House & Land Packages
2. Off-the-Plan properties
3. Construction Loans
4. Development Finance

However, new build and development projects typically involve more financing and execution risks, such as:

1. Longer construction periods;
2. Potential increases in construction costs;
3. Builder delays or contract variation risks;
4. Project valuation fluctuations;
5. Management of progress payments.

Concurrently, if investor interest in existing properties wanes, the investment logic in some markets may gradually shift from "reliance on short-term capital appreciation" to "greater emphasis on stable rental income and long-term holding capacity."

Tax advantages for existing investment properties are not completely gone, but cash flow management will become more crucial

For investors planning to purchase existing properties, while tax benefits do not entirely disappear, in a high-inflation environment, if Capital Gains Tax is adjusted to an inflation-indexed cost base, the actual taxable gain for some investors upon eventual sale may not necessarily be higher than under the current system.

However, for most investors, the more direct impact will be on cash flow during the holding period:

1. Inability to immediately receive tax refunds through negative gearing;
2. Increased after-tax holding costs;
3. Reduced disposable cash;
4. Some borrowers' serviceability might be affected when banks assess borrowing capacity.

Interest Only strategies may require re-evaluation

Historically, many investors used Interest Only loans to:

1. Reduce upfront cash flow pressure;
2. Maximise deductible interest;
3. Invest more capital into other ventures;
4. Realise gains in the future through sale or refinancing.

If the immediate negative gearing advantage diminishes, the attractiveness of this strategy may decline.

The reasons are:

1. Interest Only loans inherently incur more total interest expenditure;
2. This additional interest may not be partially offset by immediate tax benefits;
3. For investors planning short-term holding and sale, additional interest could further compress final after-tax profits.

This does not mean Interest Only is no longer suitable, but investors need to more carefully assess their cash flow, holding period, and overall investment objectives.

Why is it worth re-evaluating before 1 July 2027?

Even if the above measures have not completed the legislative process, this budget clearly signals the future policy direction.

For investors, now is a critical window to re-examine overall investment and financing strategies, particularly to consider the following questions:

1. Does your current property portfolio hold long-term investment value?
2. Are rental income and cash flow sufficient to support continued holding?
3. Is projected property price growth sufficient to cover potentially increased future tax burdens and holding costs?
4. Do you need to adjust your loan structure or make additional principal repayments?
5. Does your overall asset allocation still align with your long-term wealth planning?

This budget has not altered the fundamental logic of property investment; rather, it has reduced the relative importance of tax incentives in investment decisions, making cash flow quality, holding capacity, and the long-term value of the asset itself more critical.

It is important to emphasise that the aforementioned measures are currently budget proposals, have not yet completed legislation, and may not all be passed. Even if formally implemented in the future, subsequent governments may continue to adjust policies based on economic conditions.

However, regardless of the final legislative outcome, this budget offers investors a crucial opportunity to re-evaluate their loan structures, investment strategies, and overall asset allocation.
