Australia Trading Taxes and CGT Discount

Australia has no separate capital gains tax. Instead, capital gains are folded into your income tax — but a single discount rewards patience with a 50% cut to the taxable gain.

The Australian system is simple in principle and punishing for the impatient. The 12-month holding line is the single most important threshold in Australian trading tax.

The 50% CGT discount

For individuals and trusts, capital gains on assets held longer than 12 months receive a 50% discount:

Holding period	Taxable portion	Rate
≤ 12 months	100% of gain	Marginal income rate
> 12 months	50% of gain	Marginal income rate

A $20,000 gain on a position held 13 months creates only $10,000 of taxable income. The same gain held 11 months is fully taxable. The 12-month cliff is the most aggressive long-term incentive in any major tax regime.

The discount applies only to capital gains, not income from a business of trading. Active day trading reclassified as a business loses the discount.

Capital losses

Capital losses can offset capital gains — never other income. Unused losses carry forward indefinitely until a gain appears. This makes loss harvesting meaningful: realizing a loss in the same year as a gain directly reduces tax.

Crypto is an asset

The ATO treats cryptocurrency as a CGT asset. Every disposal — whether for fiat, for another crypto, or for goods — is a CGT event. Buying crypto is not taxable; spending or trading it is. The same 12-month discount applies to crypto held as an investment.

No formal wash sale rule, but…

Australia has no statutory wash sale rule, but the ATO applies general anti-avoidance provisions (Part IVA) to transactions whose dominant purpose is to create a tax loss. Repurchasing the same asset immediately after a loss sale can be challenged.

Practical steps

1. Track the acquisition date of every position — it decides the discount
2. Realize long-term gains first; the discount is worth more than timing
3. Harvest capital losses in years with large gains
4. Keep crypto-to-crypto trades recorded — each is a CGT event
5. If you trade very frequently, consider whether the ATO might classify you as a business

The patience premium

An Australian trader holding winners 13 months instead of 11 doubles their after-tax return on the gain. Patience is not just a strategy — it is the tax code.
