Fair Market Value (FMV) Australia 2025: Your Complete Guide

Fair Market Value (FMV) is a term that pops up everywhere—property sales, investment portfolios, even ATO tax calculations. But in 2025, with ongoing property market shifts and updated tax guidance, understanding FMV is more crucial than ever for Australians navigating big financial decisions.

What Is Fair Market Value—and Why Does It Matter in 2025?

Fair Market Value refers to the price an asset would sell for on the open market, assuming both buyer and seller are well-informed, willing, and not under pressure to transact. In Australia, FMV underpins everything from real estate deals to super fund transfers and capital gains tax (CGT) calculations.

• Property sales: FMV determines listing prices, settlement values, and loan-to-value ratios for mortgages.

• Investments: FMV is used to value shares, managed funds, and collectibles for portfolio reviews and tax events.

• Taxation: The ATO uses FMV to assess CGT, especially for inherited assets, gifts, and non-arm’s length transactions.

In 2025, rising interest rates and increased scrutiny by regulators have made accurate FMV assessments a key compliance issue. For example, recent ATO rulings clarify the need for substantiated valuations when transferring property between related parties or SMSFs.

How FMV Is Determined in Australia

There’s no single formula for FMV; it’s about what a reasonable buyer would pay and a reasonable seller would accept. Here are the most common methods:

• Comparable Sales: Analysing recent sales of similar assets in the same area. For residential property, CoreLogic and Domain data are commonly used.

• Income Approach: Especially for investment properties, this looks at rental yields and capitalisation rates.

• Cost Approach: Calculates what it would cost to replace or reproduce the asset, minus depreciation.

• Expert Valuations: For complex or unique assets (artwork, rare collectibles, business interests), an independent valuer may be required.

Since July 2024, ATO guidance has tightened, especially around SMSF asset transfers. Trustees must provide documented, independent evidence to support FMV, such as recent sales data or a formal valuation report, not just an estimate or a figure from a related party.

Real-World Examples: FMV in Action

Let’s look at how FMV affects everyday Australians in 2025:

• Selling a Family Home: With property prices fluctuating, an owner in Melbourne’s inner west uses a licensed valuer and recent sales to justify a listing price. Their lender also relies on FMV for the mortgage assessment.

• SMSF Property Transfer: An SMSF trustee wants to transfer an investment property to a related party. A formal valuation is required to avoid penalties and ensure the transaction reflects FMV, as per ATO guidelines.

• Capital Gains Tax: An investor gifting shares to a family member must declare the FMV at the date of transfer to calculate CGT, even if no money changes hands.

It’s not just big-ticket items. FMV can impact everyday transactions—think inherited jewellery, rare coins, or even business assets sold between family members. The right FMV can mean the difference between a smooth ATO audit and a costly dispute.

FMV Pitfalls and How to Avoid Them in 2025

• DIY Valuations: The ATO increasingly rejects self-assessed values for significant transactions. Independent evidence is a must, especially for SMSFs.

• Market Volatility: With property and share markets moving fast, FMV can shift within weeks. Use the most up-to-date data available and note the valuation date.

• Documentation: Keep records of how FMV was determined—sales data, valuation reports, emails from agents—especially if you expect a tax event or audit.

For 2025, the message is clear: FMV is not just a number. It’s a defensible, evidence-based value that can make or break your financial outcomes.

Conclusion: Make FMV Work for You

Whether you’re selling property, managing an SMSF, or gifting shares, understanding and documenting fair market value is essential in 2025’s regulatory environment. Take the time to get it right—using real data and independent expertise—and you’ll safeguard your wealth and peace of mind.
