Same property. Same sale price. Different tax outcome.

Three things property investors should understand 

Misconception: you’ll receive a CGT bill in 2027. 

You won’t. The transition effectively separates the gain accumulated before 1 July 2027 from the gain accumulated afterwards. Tax is generally deferred until a future CGT event, such as when you eventually sell the property. 

Risk: a lower value around 30 June 2027 could increase your future CGT bill. 

If property values happen to be softer around the crossover date and then recover, more of that recovery could fall into the post-2027 CGT regime. 

That doesn’t mean you’ve made an additional gain. But it could mean you pay more tax on that gain, because a greater portion is taxed under the new rules rather than potentially benefiting from the existing 50% CGT discount. 

In other words, a temporary dip in value at the wrong time could affect the tax outcome years later, even if the property eventually recovers to the same sale price. 

Opportunity: investors have time to understand their position before the new rules commence. 

For anyone already considering selling, there may be value in comparing the tax outcome of a sale before 1 July 2027 with a longer hold under the new rules. 

For longer-term investors, getting records and valuation evidence in order could also become particularly important. 

There is no one-size-fits-all answer, but there is an opportunity to plan rather than deal with the calculation years later. 

Why the 30 June 2027 value could matter 

Consider a simplified example. 

An investor owns a property that has previously reached a market value of $1 million. By 30 June 2027, weaker market conditions have pushed its value down to $800,000. 

They don’t sell. A few years later, the property recovers and is sold for $1 million. 

It would be easy to look at the recovery from $800,000 to $1 million and think the reforms have created an additional $200,000 gain. 

They haven’t. 

The $200,000 is still part of the property’s overall gain since purchase. The difference is that, if $800,000 forms the relevant transition value, the recovery occurs after 1 July 2027 and could therefore fall within the new CGT regime. 

That matters because the post-2027 portion may be taxed less concessionally than it would have been under the current 50% CGT discount. 

If the property had instead been worth $1 million around the crossover date and was later sold for the same $1 million, there may be little or no post-2027 capital growth. 

Same property. Same eventual sale price. Potentially a different tax bill. 

This is why a temporary dip in value around the crossover could have consequences years later.

The valuation itself matters too

One of the practical issues investors will need to consider is how the property’s position around 30 June 2027 is established. 

A properly evidenced market valuation may be one option. The reforms also contemplate an apportionment methodology that estimates how much of the gain belongs on either side of 1 July 2027, although some of that detail is still being finalised. 

That choice shouldn’t necessarily be treated as a formality. 

Property values rarely rise at a steady rate. A property can experience periods of strong growth, flat conditions and declines over the course of ownership, so an apportionment formula and an actual market valuation may produce different outcomes. 

For property owners, maintaining reliable evidence around the crossover date could therefore become important when the property is eventually sold. 

What should property investors be discussing with their accountant?

There is still time before the new regime begins, and some implementation details continue to be developed. Rather than making decisions based on headlines or broad rules of thumb, investors should understand how the changes apply to their own assets. 

Useful conversations with your accountant may include: 

• Whether a formal valuation should be obtained around 30 June 2027.
  A properly evidenced value may be important if the property is not sold for many years and the ATO later examines the calculation. 

• Whether market valuation or the eventual apportionment method produces a more appropriate outcome.
  Once the final rules are available, the two approaches may need to be modelled rather than assuming one will automatically be better. 

• The impact of selling before or after 1 July 2027.
  For investors already considering a sale, comparing the tax consequences on either side of the transition date may be worthwhile. 

• Whether the property qualifies for different treatment.
  New residential builds, main residences, affordable housing and some other circumstances may be treated differently under the legislation. 

• What records should be preserved now.
  Purchase documents, improvement costs, ownership records and evidence supporting the property’s transition-date value may become important years after 2027. 

The opportunity now is to prepare

The biggest misconception about these changes may be that investors need to make an immediate decision. 

For many people, the more important step now is understanding the rules, preserving the right evidence and knowing what decisions may need to be made as July 2027 approaches. 

For some investors, that might mean arranging a properly supported valuation. For someone already considering selling, it could mean comparing the tax consequences of selling before or after the change.
