Australia Crypto & Forex Tax 2026: CGT, the 50% Discount and ATO Data Matching

Australia taxes crypto under CGT at marginal rates of 19-45%, with a 50% discount for assets held more than 1 year. Crypto-to-crypto swaps are taxable events, and the ATO data-matches exchange records — making unreported trades increasingly hard to hide.

CGT at Marginal Rates and the 50% Discount

Capital gains are taxed at your marginal rate, from 19% up to 45%. Hold the asset for more than 1 year and only half the gain is taxed — the 50% CGT discount.

• Marginal rates run from 19% to 45%.
• 50% discount applies to assets held over 1 year.
• Capital losses carry forward to future years.

Crypto-to-Crypto Swaps and Income Assessment

Every crypto-to-crypto swap is a taxable disposal — the gain or loss is realised at fair market value, even though no cash is involved.

Frequent trading can change the picture: where activity looks like a business, the ATO may assess your profits as ordinary income instead of capital gains, removing access to the 50% discount.

What Changed in 2026

• The ATO data-matches exchange records against tax returns.

Losses and Filing Dates

Capital losses carry forward to future years — they reduce future capital gains only. Lodgment is due 31 October 2026 for self-preparers; using a registered tax agent extends the deadline to 15 May 2027.
