Crypto Capital Gains Tax Estimator (Australia)

Every disposal of cryptocurrency — selling for AUD, swapping one coin for another, or spending it — is a capital gains tax (CGT) event in Australia. This estimator applies the two rules that matter most: the 50% CGT discount for assets held longer than 12 months, and your marginal tax rate.

Cost base (what you paid, AUD) Sale proceeds (what you sold for, AUD) Held for more than 12 months? Your marginal tax rate (including Medicare levy)

Educational estimate only — each crypto disposal is a separate CGT event and personal circumstances vary. See the crypto tax guide and confirm with a registered tax agent.

How the estimate works #

Capital gain = sale proceeds − cost base (what you paid, including fees).
If you held the asset for more than 12 months before disposing, the gain is halved first (the ATO’s 50% CGT discount).
The discounted gain is taxed at your marginal rate — it simply lands on top of your other taxable income.

For the full picture — loss offsetting, the $10,000 personal-use anomaly, staking income vs capital gains, and record-keeping — read the complete crypto tax guide.

This is an educational estimate, not tax advice: it simplifies the rules and can’t cover your circumstances. For your actual return, talk to a registered tax agent — and confirm anything uncertain against the ATO’s own guidance.
