One Date Every Sunshine Coast Property Investor Needs to Know

If you own an investment property on the Sunshine Coast, there is one date that should be on your radar right now: 1 July 2027.

That’s the date the Federal Government’s capital gains tax reforms take effect, and according to industry experts, the value of your investment property on that single day could become one of the most financially significant numbers it ever produces.

Here’s why that matters and what you can do about it before then.

What’s actually changing?

Under the current rules, if you sell an investment property you’ve owned for at least 12 months, you generally only pay tax on 50 per cent of the capital gain. That 50 per cent CGT discount is now legislated to end from 1 July 2027, replaced by a cost-base indexation method and a minimum 30 per cent tax on real gains.

These changes affect investors who own or purchase established residential properties after Budget night on 12 May 2026, making the transition date relevant not just for long-term owners but for anyone who has bought or is considering buying an investment property between now and July 2027.

The good news is that any growth your property has accumulated up to that date will still be treated under the existing more favourable rules. It’s only gains realised after July 2027 that fall under the new regime.

Why does your property’s value on that date matter so much?

When you eventually sell, your total gain will be split into two periods: growth that occurred before July 2027 and growth that occurred after. The number sitting between those two periods is your property’s market value at the transition date. According to property valuer Anna Porter Primmer from Suburbanite, that figure is potentially one of the most financially important numbers your investment property will ever produce.

Get that number right and more of your gain falls under the old 50 per cent discount rules. Get it wrong and a larger share may be dragged into the new tax treatment.

Professional valuation versus the ATO default

If you don’t arrange a professional valuation, the ATO has a fallback calculation method that spreads your property’s growth evenly across the full period of ownership. The problem is that property markets don’t actually move that way and the Sunshine Coast is a clear example of this.

Our region experienced significant growth between 2020 and 2024, followed by a period of more modest movement. Valuation firm Opteon modelled six sample properties across three states and found that in five of the six scenarios, a professional valuation produced a better outcome for the property owner than the ATO’s default formula. A formula that smooths growth evenly can misrepresent when value was actually created and push more of the gain into the post-2027 tax treatment than the evidence would justify.

When do you need to act?

The valuation is assessed as at 1 July 2027, but Opteon managing director Scott Chapman recommends starting early. Completing the process ahead of time means your report isn’t sitting at the back of a long queue as the deadline approaches and a retrospective valuation completed 12 months or more after the transition date can cost significantly more due to the additional research involved.

There is also another practical reason to move early. There is still time before July 2027 to make cost-effective improvements to your property that could positively influence its assessed value, things like refreshing paintwork, improving street appeal, updating light fittings or addressing any deferred maintenance.

What we recommend

This is not the kind of decision to leave until the last minute or hand entirely to a formula. Talk to your accountant about your specific situation and consider arranging a registered valuation before the transition date.
