Australian CGT Rules

50% CGT Discount: If you held the asset for more than 12 months, only 50% of the net capital gain is included in your taxable income. This is the most important CGT concession for individuals.

Cost Base: Includes purchase price + stamp duty + agent fees + capital improvements + legal costs. For shares: include brokerage both ways.

Capital Losses: Must be offset against capital gains first. Excess losses can be carried forward indefinitely to offset future gains.

CGT on Crypto: The ATO treats cryptocurrency as a CGT asset, not currency. Every disposal (sale, trade, purchase) is a CGT event. Keeping accurate records is essential.
