Capital Gains Tax Property Valuation Explained

How professional valuations minimise your CGT liability

What is Capital Gains Tax on Property?

Capital Gains Tax (CGT) is not a separate tax—it's part of your income tax. When you sell an asset (including property) for more than you paid for it, the profit is added to your assessable income and taxed at your marginal tax rate.

However, you can potentially reduce your CGT liability through a professional property valuation. The key lies in correctly calculating your cost base—the original purchase price plus eligible expenses—and determining if any exemptions apply.

How Property Valuations Affect Your CGT

A professional property valuation is crucial for CGT calculations because it establishes the market value of your property at key dates. This affects your calculation in several ways:

Cost Base Determination

If you acquired the property before 1985 (before CGT was introduced), a valuation at 30 September 1985 establishes your starting cost base. This can significantly reduce or eliminate CGT.

Partial Exemptions

For properties used partly for rental or investment, a valuation helps calculate the taxable portion versus the exempt portion (e.g., main residence exemption).

Disputed Assessments

If the ATO disputes your cost base claims, a professional valuation from a qualified valuer provides authoritative evidence to support your position.

Main Residence Exemption

The main residence exemption is one of the most valuable CGT concessions. If a property was your main residence throughout your ownership, the full gain may be exempt from CGT. However, complications arise when:

  • You've moved out and rented the property
  • The property was used for income-producing purposes
  • You own multiple properties
  • The property was acquired after you moved in
  • You're selling an investment property
  • It's a deceased estate situation

Important: A professional valuation can help maximise your main residence exemption by accurately determining the property's value at the time you started renting it out or at other key dates.
