Treasury Laws Amendment Act 2026: Why Property Investors Need Market Valuations Before July 2027
Following the passage of the Treasury Laws Amendment Act 2026 through the Australian Parliament, property investors, accountants, and financial advisers are being urged to prepare for fundamental changes to the national Capital Gains Tax (CGT) framework.
The newly enacted legislation introduces significant changes to how capital gains will apply starting 1 July 2027. A central implication for property owners is the critical need to establish an independent, defensible market valuation for investment properties as of the commencement date.
Establishing a Defensible Base Value for Capital Gains
Under the new CGT regime, obtaining a formal market valuation as at 1 July 2027 will establish the property’s benchmark value at the start of the law’s implementation.
According to property valuation firm Herron Todd White, securing a professional valuation at this key milestone provides vital evidence to support accurate tax calculations when the asset is eventually sold in future years.
“This valuation supports the property’s market value at the commencement of the new capital gains tax regime and provides important evidence when calculating capital gains tax if the property is sold in the future,” Herron Todd White highlighted in its advisory update.
Implications for Accountants, Lawyers, and Financial Advisers
The legislative reforms affect not only individual real estate investors, but also the professional advisory sector. Accountants, tax lawyers, and financial planners managing client portfolios will need to determine when an independent property valuation is required to ensure tax compliance and avoid future disputes with tax authorities.
To support practitioners and property owners during the transition, Herron Todd White has launched a suite of educational tools, including:
- Ongoing Educational Updates: Practical articles and market insights covering the evolving tax landscape.
- CPD-Eligible On-Demand Webinar: Featuring analysis from experts across taxation law and real estate valuation.
- Tax Reform & Property Valuation Guide: A comprehensive resource detailing the operational impact of the Act.
Preparing for July 2027
With the implementation date set for mid-2027, advisory firms recommend that investors begin reviewing their residential and commercial portfolios early to identify assets that will require formal valuation reports.
