Australia’s property investors are facing significant changes to the tax treatment of residential investment property from 1 July 2027.

The 2026 Federal Budget introduces reforms to both negative gearing and capital gains tax (CGT). Together, these changes could affect how investors claim rental property losses, calculate future capital gains and assess whether a property investment remains suitable under the new rules.

The changes are prospective, with important grandfathering arrangements for existing investments. New-build investors will also have different options available under the CGT reforms.

For property investors, understanding what is changing — and what is staying the same — is essential before making investment or restructuring decisions.

What Is Changing From 1 July 2027?

From 1 July 2027, the Government will:

• Limit negative gearing for residential property investments to new builds
• Replace the existing 50% CGT discount with an inflation-based approach
• Introduce a minimum 30% tax rate on real capital gains
• Grandfather existing arrangements for qualifying investments made before the relevant commencement date

The Government says the reforms are designed to direct tax support towards new housing supply while changing the taxation of capital gains to focus on real gains after inflation.

These are separate changes, but they can be particularly important when considered together by property investors.

What Is Negative Gearing?

Negative gearing occurs when the deductible costs associated with an investment property are greater than the rental income it generates.

For example, an investor may receive $30,000 in rental income but have $40,000 in eligible expenses and interest costs.

The resulting $10,000 loss may be deductible against other income, subject to the applicable tax rules.

This can make negatively geared property attractive to some investors because the tax deduction can reduce their taxable income.

However, negative gearing does not mean an investment is automatically profitable.

The investor is still carrying an overall cash loss, with the tax deduction only reducing part of the financial impact.

How Will Negative Gearing Change?

From 1 July 2027, negative gearing for residential property will be limited to new builds.

This means investors purchasing existing residential properties after the commencement date will generally no longer be able to use rental property losses against other income in the same way.

The Government’s stated objective is to direct tax support towards new housing supply.

Importantly, this does not mean negative gearing is being completely abolished.

Investors who purchase qualifying new-build residential property will still be able to deduct losses against other income under the new arrangements.

What Happens If You Already Own an Investment Property?

This is one of the most important parts of the reform.

Existing arrangements are being grandfathered for qualifying properties acquired before Budget night, 12 May 2026.

This means existing investors are not simply being forced into the new negative gearing rules because of the 2027 changes.

The Government has stated that existing arrangements will remain unchanged for investments made before 7:30 pm AEST on 12 May 2026.

The legislation passed by Parliament in June 2026 also included grandfathering provisions for existing investment property owners.

This makes the acquisition date of an investment property particularly important when considering how the new rules may apply.

What If You Buy an Existing Property After 1 July 2027?

This is where future investors may experience a significant difference.

If an investor purchases an existing residential property after the new rules commence, the property will generally not receive the same negative gearing treatment as a qualifying new build.

The investor will therefore need to consider the property’s rental income, deductible expenses, financing costs and overall cash flow without assuming that a rental loss can simply be offset against other income.

This could change the way investors assess potential properties.

Instead of focusing primarily on the potential tax deduction, investors may need to place greater emphasis on:

• Rental yield
• Financing costs
• Vacancy risk
• Property expenses
• Expected capital growth
• Cash flow
• Location
• Long-term investment objectives

What Is Changing With Capital Gains Tax?

Negative gearing is only one part of the property tax reforms.

From 1 July 2027, the Government is also replacing the existing 50% CGT discount with a new approach based on inflation.

Under the new system, the cost base of an eligible asset will be adjusted for inflation, meaning investors will generally be taxed on the real capital gain rather than the portion of the gain attributable to inflation.

A minimum tax rate of 30% will also apply to real capital gains under the new arrangements.

The reforms will apply prospectively to capital gains accruing from 1 July 2027.

Capital gains that accrued before that date retain access to the existing 50% discount under the transitional arrangements.

What Does This Mean for Property Investors?

The CGT changes could affect investors differently depending on factors such as:

• When the property was purchased
• How long it has been owned
• The property’s historical cost
• How much it has appreciated
• Inflation over the ownership period
• When the property is eventually sold
• Whether it is an existing property or qualifying new build

This means investors should avoid assuming that the new rules will automatically make selling or holding a property better or worse.

The actual outcome will depend on the individual investment.

New Builds Have an Important Advantage

The Government has provided special treatment for investors purchasing new builds.

New-build investors can choose between the existing 50% CGT discount and the new inflation-based arrangements when the new CGT rules apply.

New builds can also continue to receive negative gearing treatment under the new rules.

This makes new residential construction particularly important under the 2026 reforms.

However, investors should not assume that every renovation, knock-down rebuild or property advertised as “new” will automatically qualify.

The relevant tax rules and definitions need to be considered before relying on the new-build treatment.

A Simple Example

Consider two investors purchasing residential property after the reforms commence.

Investor A purchases an existing investment property.

The property produces a rental loss, but because it is not a qualifying new build, the investor may not receive the same ability to offset that loss against other income under the new negative gearing rules.

Investor B purchases a qualifying new-build property.

The investor can continue to access negative gearing treatment, subject to the normal requirements.

The new-build investor may also have a choice regarding the CGT treatment when the property is eventually sold.

This illustrates why the type of property could become increasingly important when comparing investment opportunities.

Should Existing Property Investors Sell?

Not necessarily.

The reforms do not automatically mean existing investment properties should be sold.

An existing investor should consider the entire investment position, including:

• Current rental income
• Mortgage interest
• Property expenses
• Existing tax benefits
• Potential capital growth
• Expected future rent
• CGT consequences
• Long-term investment goals
• Personal cash flow

Selling a property simply because tax rules are changing could create its own tax and transaction costs.

The better approach is to model the numbers before making a major decision.

Should Investors Buy Before 1 July 2027?

There is no universal answer.

The commencement date may be relevant when considering a future investment, but tax should not be the only factor driving a property purchase.

Investors should also consider whether the property is financially viable without relying heavily on tax deductions.

A property that produces a strong rental return and makes sense as a long-term investment may remain attractive even under different tax rules.

Conversely, buying a property purely to obtain a tax benefit can create unnecessary financial risk.

What Should Property Investors Do Now?

The 2026 reforms make it worthwhile for investors to review their property strategies early.

Review Existing Properties

Understand how grandfathering applies to properties already owned and how the future CGT rules could affect eventual disposal.

Review Planned Purchases

If you are considering purchasing an investment property, understand whether it is an existing property or a qualifying new build and how the new rules could affect the investment.

Model Cash Flow

Calculate the investment’s expected rental income, expenses, interest costs, and cash flow without relying solely on tax deductions.

Understand Your CGT Position

Consider the property’s cost base, expected growth and potential tax consequences before making decisions about buying or selling.

Property tax can become complicated when negative gearing, CGT, ownership structures, financing and future investment plans overlap.

Getting advice before committing to a major transaction can help you understand the potential consequences.

The Bottom Line for Property Investors

The 2026 tax reforms represent a significant change to Australia’s property investment landscape.

From 1 July 2027, negative gearing for residential property will generally be limited to new builds, while the existing 50% CGT discount will be replaced with an inflation-based approach and a minimum 30% tax rate on real capital gains.

However, existing investments made before Budget night are protected by grandfathering arrangements, and new-build investors will have important options under the CGT reforms.

For property investors, the key is not to react to the headline changes alone.

The right investment strategy will depend on the property’s cash flow, expected growth, financing, ownership structure, tax position and long-term goals.
