In the US, the IRS treats gambling winnings as taxable income. In Australia, the ATO does not. That single difference changes how crypto gambling is taxed here.

Are crypto gambling winnings taxed in Australia?

For a recreational gambler, no. The ATO treats gambling winnings as a windfall from a recreational activity, not assessable income, whether the platform pays you in AUD or in crypto. The flip side: gambling losses are not deductible.

There is an exception. If you gamble as a business or in a business-like, professional manner (regular, organised, systematic, with a profit-making intention and relied on as income), the ATO may treat the activity as a business and your winnings as assessable. Most retail crypto gamblers are nowhere near this line.

Where crypto tax does bite: the disposals around the bet

Even though the winnings aren't taxed, the crypto you move is still a CGT asset, so two events commonly arise.

1. Using crypto to gamble is a disposal

If you fund a bet with crypto (or a platform converts your crypto to let you gamble), you've disposed of that crypto, with a capital gain or loss in AUD.

Example 1. You bought ETH for AUD 1,000. To gamble, you dispose of it when it's worth AUD 1,250: a AUD 250 capital gain, regardless of how the bet goes.

2. Selling crypto you won is a disposal

Crypto you win is a non-taxable windfall, but its AUD market value at the time you win it becomes your cost base. Selling, swapping or spending it later is a CGT event on the movement since.

Example 2. You win crypto worth AUD 500 (not taxed). You sell it later for AUD 750: a AUD 250 capital gain. The 50% discount may apply if you held it 12+ months.

How to report and keep records

Crypto casinos won't withhold Australian tax and often keep poor records. Keep your own: dates, AUD values, and the crypto in and out. You report the capital gains and losses from the disposals around your gambling, not the winnings themselves. Self-lodgers file by 31 October.

How Summ helps

Summ (formerly Crypto Tax Calculator) categorises the buys, sells and swaps tied to your gambling activity and calculates cost base and AUD gains or losses, so the taxable disposals are captured even when the winnings aren't assessable.

A word on risk

Crypto gambling carries real financial risk and fraudulent platforms are common. And because losses aren't deductible in Australia, there's no tax consolation prize for a bad night.
