Capital Gains Tax Australia | Property CGT Explained | QLoans.au
Capital Gains Tax is a key consideration for anyone selling property in Australia. Understanding how CGT works, when it applies, and what concessions may be available can materially affect your net outcome and should form part of any property or refinancing strategy.
What is Capital Gains Tax?
- Capital Gains Tax (CGT) is not a separate tax; it forms part of your income tax.
- It applies when you dispose of an asset, such as an investment property, for more than its cost base.
- The “capital gain” is the difference between:
- The sale price, and
- The original purchase price plus eligible costs (e.g. stamp duty, legal fees, certain improvements).
When Does CGT Apply to Property?
CGT generally applies when you sell:
- Investment properties
- Holiday homes
- Rental properties that were once your home (subject to partial exemptions)
- Vacant land purchased for investment
CGT typically does not apply to:
- Your principal place of residence (PPOR), provided it meets exemption criteria
- Properties sold at a loss (a capital loss may be carried forward)
The Main Residence Exemption
- Your primary home is usually exempt from CGT.
- To qualify, the property must have been:
- Your main residence for the entire ownership period, and
- Not used to produce assessable income.
- Partial CGT may apply if:
- You rented out the property for part of the time
- You operated a business from the home
- The land exceeds 2 hectares
The 6-Year Rule (Common Investor Strategy)
- If you move out of your main residence and rent it out, you may:
- Continue to treat it as your main residence for up to six years
- Avoid CGT if sold within that period
- You cannot claim another property as your main residence during the same time.
CGT Discount for Individuals
- Individuals and trusts may be eligible for a 50% CGT discount if:
- The property was held for more than 12 months
- This can significantly reduce the taxable gain.
- Companies are not eligible for the 50% discount.
How CGT is Calculated (Simplified)
- Capital gain = Sale price – Cost base
- Apply any:
- Capital losses
- CGT discount (if eligible)
- The remaining amount is added to your taxable income for that financial year and taxed at your marginal rate.
CGT and Refinancing or Restructuring
- CGT is triggered by a change in ownership, not by refinancing alone.
- However, CGT may apply if:
- Property ownership is transferred between individuals or entities
- Assets are moved into trusts or companies
- These decisions should be assessed carefully with tax and lending advice aligned.
Why CGT Matters When Planning Property Finance
From a mortgage broker’s perspective, CGT impacts:
- Whether selling or retaining a property is financially viable
- Equity release and long-term portfolio strategy
- Timing decisions around upgrades, downsizing, or investment exits
- Cash flow planning following a sale
A well-structured lending strategy should consider after-tax outcomes, not just borrowing capacity or interest rates.
Key Takeaways
- CGT can materially affect your net proceeds when selling property.
- Exemptions and concessions may apply, but rules are strict.
- Strategic timing and structure can reduce tax exposure.
- CGT should be considered alongside lending, cash flow, and long-term goals.

If you are considering selling, refinancing, or restructuring property ownership, speak with a qualified tax adviser and a mortgage broker who understands how tax and lending strategies intersect.
