Australia Crypto Tax Calculator

The ATO treats crypto as a capital gains tax asset. When you dispose of it you make a capital gain or loss. Your net capital gain for the year is added to your taxable income and taxed at your marginal rate, so there is no separate rate for crypto.

It depends on your income and how long you held the crypto. Take someone with $90,000 of other taxable income who sells 0.5 BTC bought at $100,000 per BTC for $160,000 per BTC, a gain of $30,000. Held for 12 months or more, only $15,000 is taxed: $4,500 income tax at 30% plus $300 Medicare levy, $4,800 in total. Held for less than 12 months, the whole $30,000 is taxed and the bill is $9,600.

Individuals who hold an asset for at least 12 months before disposing of it reduce the capital gain by 50%. The day you acquired the crypto and the day you disposed of it are both left out when counting the 12 months. Capital losses are subtracted before the discount is applied.

Yes. From 1 July 2027 the 50% discount is replaced by cost base indexation, which taxes only the gain above inflation, together with a 30% minimum tax on capital gains. The change applies to gains that build up after that date. This calculator covers the 2026–27 income year, when the 50% discount still applies.

Yes. Swapping one crypto for another is a disposal of the first one, so a CGT event happens even though you received no cash. Your proceeds are the market value in Australian dollars of the crypto you received. Spending crypto on goods or services, and gifting it, are CGT events too.

A capital loss reduces your capital gains for the year, and it is applied before the CGT discount. It cannot be used against other income such as wages. If your losses are larger than your gains, the unused part carries forward to later years.

A capital gain is exempt if the crypto is a personal use asset and you acquired it for less than $10,000. That generally means crypto you bought and used fairly soon to pay for personal items. Crypto you keep as an investment, or to make a profit, is not a personal use asset.

Yes. The Medicare levy is 2% of your taxable income, and your net capital gain is part of that. People on low incomes pay a reduced levy or none. The calculator uses the 2025–26 low-income thresholds for singles, the latest published: no levy up to $28,011, and a reduced levy up to $35,013.

Most people who buy and hold crypto are investors, and their gains are capital gains. If you carry on a business of trading crypto, your profit is ordinary income instead, with no CGT discount. This calculator works out the investor case.

It multiplies your buy and sell prices by the quantity and subtracts fees to get the capital gain, then halves it if you held the crypto for 12 months or more. It places that net gain on top of your other taxable income and applies the 2026–27 resident rates, the low income tax offset and the Medicare levy. On a loss, tax is $0.
