30 June 2027: A Date Queensland Property Investors Should Know

If you own an investment property, put 30 June 2027 on your radar.

Capital Gains Tax (CGT) rules change from 1 July 2027, and this is no longer just a proposal. The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 received Royal Assent on 26 June 2026, so the changes are now law.

I’m a real estate agent, not a tax adviser, so I won’t tell you what this means for your personal tax position. That’s a conversation for your accountant or registered tax agent.

What I can explain is why the date matters from a property perspective and what may be worth keeping on file.

What’s changing?

For affected taxpayers and assets, the current 50% CGT discount is being replaced with cost base indexation, which takes inflation into account, together with a 30% minimum tax rate on real capital gains.

Importantly, the change is prospective, not retrospective.

Gains accrued before 1 July 2027 remain under the existing rules, while gains accruing from that date fall under the new system.

There are exceptions and special rules, so the impact will depend on your individual circumstances, including your purchase price, cost base, how long you hold the property and when you eventually sell.

Why does 30 June 2027 matter?

For properties held across the transition, the property’s market value immediately before 1 July 2027 may be relevant to the transitional calculation.

That’s why property valuations are suddenly being talked about.

It does not mean every investment property owner needs to obtain a formal valuation on 30 June 2027. The transitional rules provide different ways of determining the gain attributable to the periods before and after 1 July 2027.

For example, if you bought an investment property years ago and it has increased substantially in value, some of that growth occurred before the new rules and some may occur after them.

How that gain is ultimately treated is for your tax adviser to determine. From a property perspective, having good records and evidence of market conditions around the transition date could be useful, particularly if you don’t sell for many years.

Reaching 30 June 2027 does not itself trigger a tax bill. CGT generally becomes relevant when you sell the property or another CGT event occurs.

Do you need a valuation?

Your accountant or registered tax agent should be your first call. They can tell you what evidence they recommend keeping and whether a formal valuation is appropriate for your circumstances.

If a formal valuation for taxation purposes is required, it should be completed by an appropriately qualified independent property valuer.

A real estate agent can provide an appraisal, comparable sales and information about local market conditions. These can be useful records, but an agent’s appraisal is not automatically a substitute for a formal valuation for taxation purposes.

What should you do now?

Nothing dramatic.

Consider starting a folder called “30 June 2027 Property Records” and keep relevant documents together, including your purchase contract, settlement statement, renovation and improvement invoices, depreciation schedules, photographs and other records relating to the property.

Closer to the date, check with your accountant about whether they would also like you to retain an appraisal, comparable sales evidence or a formal valuation.

You may not need these records for many years, but keeping them now could save you trying to reconstruct what your property and the market looked like in 2027 when you eventually sell.

If your accountant recommends an appraisal or comparable sales evidence, Tafolo Realty can help with the property side. If they recommend a formal valuation for taxation purposes, that’s a job for a qualified valuer.

There is still time before 30 June 2027. The important thing is to be informed, keep good records and get advice that is appropriate for your circumstances.
