Australia Crypto tax calculator

How crypto tax is calculated

Every major tax authority treats cryptocurrency as property or an asset for tax purposes, not currency. That means almost every meaningful action with crypto can be a taxable event.

Taxable crypto events

• Selling crypto for fiat — disposal, capital gain/loss
• Swapping one crypto for another — disposal of the first + acquisition of the second at market value
• Spending crypto — disposal at market value at time of spend
• Receiving crypto as income (mining, staking rewards, paid for work) — ordinary income at receipt
• Airdrops — typically ordinary income at fair market value when received

Non-taxable

• Buying crypto with fiat — no taxable event until you dispose
• Holding — no taxable event
• Transferring between your own wallets — no taxable event
• Gifting crypto — usually not taxable to giver within annual limits; recipient inherits cost basis

Worked example (US, single, $90,000 salary)

• January: bought 1 BTC at $40,000
• June: swapped 0.5 BTC (now worth $30,000) for ETH
• December: sold 0.5 BTC for $35,000 in fiat

June swap: Disposed 0.5 BTC at $30,000. Basis: 0.5 × $40,000 = $20,000. Gain: $10,000 (short-term) → 22% → $2,200 tax.

December sale: Disposed remaining 0.5 BTC at $35,000. Basis: $20,000. Gain: $15,000 (short-term) → 22% → $3,300 tax.

Total crypto tax: $5,500. The June swap was a taxable event even though no fiat was involved — this is the most commonly missed crypto-tax event.

Cost basis methods

US allows specific identification (choose which lot you sold), FIFO (first in, first out), or HIFO (highest in, first out — minimises gain) provided you document the choice consistently. UK uses share-pooling rules with the "same-day" and "30-day bed-and-breakfast" rules. Canada and Australia generally use the adjusted cost base (averaged across holdings).

Common mistakes

• "I haven't cashed out, so it's not taxable." Wrong — swaps, spends, and crypto income are all taxable independent of fiat conversion.
• Not tracking the cost basis of every transaction. Most retail traders end up under-reporting because their records are incomplete. Use a crypto tax tool early.
• Ignoring airdrops, forks, and staking income. These are ordinary income when received, plus a future capital event when disposed.
• Forgetting wash-sale-style rules. UK explicitly applies a 30-day matching rule to crypto. US wash-sale rules technically don't yet apply to crypto, but watch for legislation.

What this calculator doesn't cover

• DeFi events (lending interest, LP positions, yield farming)
• NFT-specific tax treatment (collectibles rates in the US)
• Lost or stolen crypto (limited deductibility)
• Wrapped tokens and bridging (treatment varies by jurisdiction)
• Multi-jurisdiction filings for crypto held across exchanges in different countries

For complex crypto situations, use a dedicated crypto tax platform (CoinTracker, Koinly, etc.) and consult an accountant familiar with crypto.
