Crypto margin trading lets you borrow funds to take a larger position than your own capital allows. Leverage is the multiple: 10x means AUD 10 of your own capital controls a AUD 100 position. It magnifies gains and losses alike, and at high leverage a small adverse move can wipe out your stake. As always, do your own research.
The tax treatment in Australia
The first question is whether you trade as an individual investor or are carrying on a business of trading. It's a facts-and-circumstances test: repetition and regularity, organisation and scale, a business plan, profit-making intention, and capital committed.
- Investor (capital account). Gains and losses from your positions and the related crypto disposals are capital gains and losses. The 50% CGT discount can apply to gains on assets held 12+ months, though active margin trading often involves short holding periods. Capital losses offset capital gains only, and carry forward.
- Business or trader (revenue account). Profits are ordinary income and losses are generally deductible against income, subject to the non-commercial loss rules. Get advice on GST and on whether your activity crosses the line.
Most retail participants are investors, but high-volume, systematic margin trading can tip into carrying on a business. This classification changes how a loss is treated, so it's worth confirming with a registered tax agent.
The events to watch
Margin trading generates a lot of taxable touchpoints: disposing of crypto to open or fund a position, closing a position, swapping between assets, and paying fees or funding and interest in crypto (each crypto fee payment is itself a disposal). Liquidation of collateral is a disposal too.
Keeping track
Active margin traders can rack up hundreds or thousands of transactions. Summ (formerly Crypto Tax Calculator) imports your data and categorises buys, sells, swaps and fees so your net AUD gains, losses or income land accurately in an ATO-ready report.
