Estimator coverage notice

This estimator does not currently support margin trading, leveraged positions, futures, or perpetual contracts. This page explains the general ATO treatment for educational purposes only. If you trade crypto on margin, consult a tax professional familiar with financial derivatives and active trader classification. See the coverage page for a full list of what this estimator does and does not support.

How the ATO treats margin trading

The ATO distinguishes between investors (who pay CGT on profits) and traders carrying on a business (whose profits are ordinary income). Margin trading does not automatically make you a trader — the ATO considers factors including trading frequency, the scale of operations, whether you have a business plan, and whether you carry on the activity in a business-like manner. If classified as a trader, profits are assessable as ordinary income and losses are deductible against other income. Interest on borrowed funds used to produce assessable income may be deductible in either case.

Worked example

You open a 3x leveraged long position on BTC worth AUD 9,000 (using AUD 3,000 of your own funds and AUD 6,000 borrowed). BTC rises and you close the position for AUD 12,000, repay the AUD 6,000 loan plus AUD 300 interest, and net AUD 5,700. If you are an investor, the AUD 2,700 profit (after interest) may be a capital gain. If you are a trader carrying on a business, the AUD 2,700 is ordinary income. Liquidation events — where the exchange closes your position automatically — create a disposal event at the liquidation price regardless of your intentions.

Common pitfalls

Liquidation events are often overlooked as taxable disposals. Funding rates on perpetual contracts (periodic payments between long and short holders) may be income or deductions depending on their direction and your classification. Cross-margin accounts that share collateral across positions create complexity when calculating the cost base for individual position closures. The trader versus investor distinction is not self-selected — the ATO may challenge your classification if your returns are inconsistent with it.

Frequently asked questions

How is crypto margin trading taxed in Australia?

The tax treatment depends on whether you are classified as a trader or an investor. Investors pay CGT on profits from leveraged positions. Active traders may have profits treated as ordinary income. The ATO looks at trading frequency, intent, and whether it constitutes a business activity.

Is interest on crypto margin loans deductible in Australia?

Potentially yes. If you are carrying on a business of trading or if the borrowing is used to produce assessable income, interest costs on margin loans may be deductible. Investors who are not carrying on a business face more restrictions on deductibility.
