How Capital Gains Tax works in Australia

In Australia, a capital gain arises when you sell an asset for more than its cost base (purchase price plus associated costs). The net gain is added to your other income and taxed at your marginal rate — there is no separate "CGT rate." The tax is effectively your marginal rate applied to the capital gain portion of your total income.

50% CGT discount: If you've held the asset for more than 12 months, you only include 50% of your capital gain in your income. This is the most valuable tax concession in the Australian system — it effectively halves your CGT rate for long-term investments.

Crypto is taxed as property, not currency. Every sale, trade, or use of cryptocurrency to purchase goods is a CGT event. Swapping one crypto for another also triggers CGT. The 12-month discount applies equally to crypto if held long enough.

Capital losses offset capital gains. Losses from one asset can be applied against gains from another in the same income year. Unapplied losses carry forward indefinitely — but they can only offset future capital gains, not other income.
