How Capital Gains Tax Calculation Works
How Your CGT is Calculated in Australia
- Calculate the Cost Base:This is the initial purchase price plus all associated buying and selling costs (like stamp duty and legal fees).
- Determine Capital Gain or Loss:Subtract the total cost base from the final sale price.
- Apply Losses and Discounts:First, subtract any available capital losses. Then, if you've held the asset for over 12 months, apply the 50% CGT discount to the remaining amount.
- Calculate Final Tax:The resulting amount is your 'taxable capital gain'. This is added to your income for the year and taxed at your personal marginal tax rate.
