Selling Property in Australia: How Much Tax Will You Pay?

  • May 1
  • 2 min read

Selling property can trigger one of the largest tax bills you will ever face. Most people only think about it at the point of sale. That is too late.

If you do not plan properly, you can easily overpay tax by tens or even hundreds of thousands.


When Do You Pay Tax on Property?


You only pay tax when a CGT event occurs. This typically happens when:

  • You sell an investment property

  • You transfer ownership

  • You gift a property

  • You lose ownership through legal or financial events


The gain is calculated as:

Sale price minus cost base

Key Factors That Determine Your Tax


Main Residence Exemption


If the property is your primary home, you may not pay any tax at all.

However, this is where most mistakes happen.


You cannot automatically claim this exemption if:

  • The property was rented at any stage

  • You moved out and kept it as an investment

  • It is owned by a trust or company

The ATO is actively reviewing incorrect claims.


Investment Property CGT

If the property is an investment:

  • You will pay tax on the capital gain

  • The gain is added to your taxable income

  • You pay tax at your marginal rate


Holding Period Discount

If you hold the property for more than 12 months:

  • You may be eligible for the 50% CGT discount

  • This halves the taxable portion of your gain

With the proposed changes, this benefit may no longer be as generous.


Cost Base Calculations


Your cost base is not just the purchase price.

It includes:

  • Stamp duty

  • Legal fees

  • Renovation costs

  • Selling costs

If you miss these, you will overpay tax.


Common Mistakes We See


  • Claiming the main residence exemption incorrectly

  • Forgetting to include renovation costs

  • Not applying the 6-year rule properly

  • Selling without understanding tax timing


Current ATO Focus


The ATO is heavily reviewing:

  • Main residence exemption claims

  • Property sale reporting

  • Data matching with land titles and banks

If your numbers do not align, you will be flagged.



How to Reduce Your Tax Legally


  • Time the sale across financial years

  • Offset gains with capital losses

  • Maximise your cost base

  • Consider ownership structure

These strategies must be done before the sale, not after.


Final Word

Property tax is not something you “figure out later”.

By the time the contract is signed, most planning opportunities are gone.
