Frequently asked questions
What is the capital gains tax rate in Australia?
There is no separate CGT rate — your net capital gain is added to your taxable income and taxed at your marginal rate (2025-26: 16%, 30%, 37% or 45% plus the 2% Medicare levy). If you held the asset more than 12 months as an individual, only half the gain is taxed, so the effective top rate on a discounted gain is about 23.5%.
How does the 50% CGT discount work?
Individuals who hold a CGT asset for more than 12 months (contract date to contract date, not settlement) only include half the gain in their taxable income. Super funds get a one-third discount and companies get none. Selling even a few days before the 12-month mark forfeits the discount and can roughly double the tax.
Is my home exempt from capital gains tax?
Usually yes — your main residence is fully exempt. Under the six-year rule it can remain exempt after you move out, even while rented, for up to six years at a time (indefinitely if not producing income). Partial CGT applies if you used part of the home to earn income or the land exceeds two hectares.
What counts in the cost base of an asset?
The purchase price plus incidental costs of buying and selling (stamp duty, conveyancing, agent commission), capital improvements, and certain ownership costs not otherwise claimed. A higher cost base means a smaller gain — keep records. For investment properties, building depreciation you have claimed reduces the cost base.
What is the indexation method for pre-1999 assets?
For assets acquired before 21 September 1999 you can choose to index the cost base by CPI (frozen at September 1999) instead of taking the 50% discount. It occasionally beats the discount for assets with large cost bases and modest gains, but for most long-held assets the discount wins. Assets bought before 20 September 1985 are exempt from CGT entirely.
Can capital losses reduce my capital gains tax?
Yes. Capital losses offset capital gains before the 50% discount is applied, and unused losses carry forward indefinitely — but they can only ever offset capital gains, not salary or other income. There is no CGT event until you dispose of the asset, so paper losses and gains have no tax effect.
