How to compute capital gains tax
Capital Gains Tax Comparison Calculator
Compare CGT outcomes for two scenarios — e.g. sell now vs hold longer, or with vs without the 50% discount.
First scenario
Second scenario
Side-by-side CGT comparison for two disposal scenarios using ATO resident rates, 50% discount and 2% Medicare levy on the taxable gain. Estimate only — confirm with the ATO or a registered tax agent.
Calculator introduction
Compare your potential capital gains tax in two different scenarios. Enter your taxable income and capital gain for each scenario to see how the outcome may change. You can compare situations such as selling an asset before or after 12 months, or with and without an eligible CGT discount.
Scenario A
Enter the capital gain for your first situation and select whether the asset was held for more than 12 months. Eligible individuals and trusts may qualify for a 50% CGT discount when an eligible asset has been held for more than 12 months.
Scenario B
The calculator estimates the potential tax outcome for each scenario based on the information entered. A longer ownership period may result in a lower taxable capital gain where the relevant CGT discount requirements are met.
Important:
This calculator provides an estimate only. Your actual CGT liability can vary depending on your circumstances, eligible costs, capital losses, deductions, Medicare levy and the tax rules that apply to you.
