Annual exempt amount 2024-25: £3,000 (reduced from £6,000 in 2023-24). You only pay CGT on gains above this threshold.

Australian CGT — 50% Discount

  • Australian residents who hold an asset for 12 months or more qualify for a 50% CGT discount — only half the gain is included in assessable income.
  • The discounted capital gain is then taxed at your marginal income tax rate (using the 2024-25 ATO brackets).
  • Assets held for less than 12 months are taxed in full at your marginal rate.
  • The main residence exemption generally exempts your primary home from CGT.
  • Capital losses can be used to offset capital gains in the same or future years.

Frequently Asked Questions

A capital gain arises when you sell an asset (such as shares, property, or cryptocurrency) for more than you paid for it. The taxable gain is generally the sale price minus the purchase price and allowable costs. Different countries and asset types have different rules and rates.
Yes. Strategies include: holding assets for 12+ months (qualifies for lower rates in US, 50% discount in Australia), offsetting gains with capital losses, using tax-free allowances (UK £3,000 / AU CGT discount), contributing gains to retirement accounts, or timing the sale across tax years. Always consult a tax advisor for personalised advice.
Yes, in most countries. The US IRS treats crypto as property — gains are subject to capital gains tax. The UK HMRC taxes crypto gains as capital gains. The ATO in Australia treats crypto as a CGT asset and the 50% discount applies for assets held 12+ months. Each disposal (sale, exchange, or use) is a taxable event.
