Property Tax Changes: Your Questions Answered

The proposed changes to capital gains tax (CGT) and negative gearing announced in the 2026 Federal Budget have raised a lot of questions for property owners, investors and future buyers.

While the reforms are still proposed legislation and may change before becoming law, many Australians are already trying to understand how the changes could affect their situation.

Below are some of the most common questions currently being asked.

Will My Existing Investment Property Be Affected?

In most cases, existing investment properties purchased before 12 May 2026 are expected to be grandfathered under the current rules.

This means:

• Existing negative gearing arrangements would generally continue.
• Existing CGT rules would largely remain in place for gains accrued before the changes commence.

The Government has indicated the reforms are primarily aimed at future property purchases rather than retrospectively changing long-held investments.

However, there may still be transitional rules and partial application of the new CGT system for gains occurring after July 2027. Final legislation will ultimately determine exactly how this works.

What Happens If I Buy an Investment Property Between Now and July 2027?

Properties purchased between budget night on 12 May 2026 and the proposed start date of 1 July 2027 are currently expected to fall under transitional arrangements.

At this stage, the proposed framework suggests:

• Investors may still be able to access current negative gearing rules until the commencement date.
• CGT treatment may depend on when gains are accrued and when the property is eventually sold.

This means the timing of both the purchase and the future sale could become important.

Because legislation has not yet been finalised, investors considering buying during this period may wish to seek independent accounting or financial advice specific to their circumstances.

What If I Buy a New Home After July 2027 and Turn My Older Property Into an Investment?

This is one of the scenarios many existing homeowners are asking about.

For example:

• You purchased your current home before 12 May 2026.
• In July 2027 or later, you buy another property to live in.
• Your original home then becomes an investment property.

Under the proposed rules currently discussed:

• The original property may still retain grandfathered treatment because it was owned before the policy cut-off date.
• This could potentially allow the property to continue qualifying under existing negative gearing and CGT arrangements, even though it later becomes an investment property.

However, the final outcome would depend on:

• The exact wording of the legislation,
• Whether ownership date or investment-use date becomes the determining factor,
• Any anti-avoidance or transitional provisions introduced.

At present, many tax professionals are waiting for draft legislation before giving definitive advice on these types of scenarios.

Do These Changes Affect My Principal Place of Residence (PPOR)?

The proposed reforms are primarily targeted at investment properties.

The family home, commonly referred to as a Principal Place of Residence (PPOR), generally remains exempt from capital gains tax under existing Australian tax law.

At this stage:

• The Government has not proposed removing the main residence exemption.
• Owner-occupied homes are not the primary target of the negative gearing changes because negative gearing generally applies to income-producing assets.

However, partial exemptions and mixed-use situations can still become complex. Examples may include:

• Homes partially used for business purposes,
• Properties rented out for periods of time,
• Airbnb or short-term accommodation use,
• Moving out and later converting a PPOR into an investment property.

These situations already have CGT implications under existing tax law and may become even more important under the proposed reforms.

Are the Changes Backdated?

One of the biggest concerns many investors have is whether gains accumulated over decades could suddenly become taxed under the new system.

For example:

• A property purchased in 2001 for $100,000,
• Worth $900,000 by 30 June 2027,
• Then sold in 2030 for $1.2 million.

Based on information released so far, the reforms are not expected to fully backdate taxation to the original purchase date. Instead, a transitional approach is expected to apply.

This could potentially mean:

• Gains accrued before the commencement date may still receive treatment under the old rules,
• Gains accrued after the commencement date may fall under the new indexation-based system.

Using the above example:

• The increase in value from $100,000 to $900,000 may largely remain under existing CGT rules,
• The growth from $900,000 to $1.2 million after the transition date may be treated differently.

However, the exact calculation method has not yet been fully legislated and may still change.

This is one of the most technically complex areas of the proposed reforms and will likely require detailed guidance from accountants and the ATO once legislation is finalised.

Why Are These Changes So Controversial?

Supporters argue the reforms could:

• Improve housing affordability,
• Reduce speculative investor demand,
• Help first-home buyers compete in the market,
• Encourage more construction of new homes.

Critics argue the reforms could:

• Reduce rental supply,
• Discourage private investment,
• Increase pressure on rents,
• Create uncertainty in the property market.

Economists, banks, tax professionals and property groups remain divided on what the long-term impacts may be.
