What is Crypto Tax?
The ATO treats cryptocurrency as a Capital Gains Tax (CGT) asset for most investors, and as trading stock or business income for traders. Disposing of crypto (selling, swapping, gifting, paying for goods) triggers a CGT event.
How this calculator works
This calculator computes capital gain (or loss) on a single crypto disposal: Proceeds (sale price - sale fees) - Cost Base (purchase price + purchase fees + sale fees). If held over 12 months, individuals get a 50% CGT discount, SMSFs get 33.33%, traders get no discount. Tax is calculated on your total income (other income + taxable gain) using current 2025-26 ATO brackets.
Investor vs Trader Classification
Most individuals are 'investors' — buying and holding crypto for capital growth. Their gains attract CGT (with 50% discount if held > 12 months). 'Traders' run a business of buying and selling — high frequency, business-like organisation, intent to profit short-term. Traders treat profits as ordinary income (no discount) but losses are fully deductible against other income. The ATO looks at: business intent, repetition, business plan, volume of activity. Most retail crypto users are investors, not traders.
What Counts as a CGT Event?
Disposing of crypto for AUD (selling on an exchange). Swapping one crypto for another (e.g. BTC → ETH). Using crypto to buy goods or services (a disposal at the AUD value). Gifting crypto to someone (treated as disposal at market value). Receiving crypto as payment, staking rewards, mining rewards, or airdrops = ordinary income at receipt (and establishes new cost base for future CGT). Wallet-to-wallet transfers (your own wallets) = NOT a CGT event.
Cost Base Tracking
ATO accepts FIFO (First In First Out) by default, or you can use specific identification if you can document which parcel was sold. Cost base includes: purchase price, exchange fees on buy and sell, transfer/network fees attributable to the asset. Keep records for 5 years after the disposal. Crypto tax software (Koinly, CoinTracker, CoinSpot) automates this.
Capital Losses and Carry-Forward
Capital losses can offset capital gains in the same year (any kind, not just crypto). Unused losses carry forward indefinitely until offset. Losses cannot offset salary or business income. If your crypto was lost or stolen and unrecoverable (hacks, exchange collapses like FTX), document it and claim a capital loss.
Personal Use Asset Exemption
If you bought crypto for less than $10,000 AND used it shortly after to buy personal goods/services (not as an investment), you may qualify for the personal use exemption. The ATO interprets this strictly — buying $5,000 of BTC to pay for a holiday booked the same week might qualify; holding for months waiting for the right rate generally won't. Most crypto purchases don't qualify.
ATO Data Matching
The ATO has data-matching agreements with all major Australian exchanges (CoinSpot, Swyftx, BTC Markets, Binance Australia, etc). Don't try to omit crypto activity — the ATO already knows. Pre-filled data will appear in your tax return.
