Capital Gains Breakdown
1. The Australian Crypto Taxation Framework (2026–27)
Cryptocurrency taxation is governed by Part 3-1 and Part 3-3 of the Income Tax Assessment Act 1997.
The ATO classifies cryptocurrency assets as CGT property. Every sale, swap, or trade triggers a CGT event requiring AUD AUD-equivalent value calculations on the date of transaction.
2. Cryptocurrency Transaction Type & CGT Benchmarks
| Transaction Type | AUD Cost Basis | Disposal Value | 50% CGT Discount | Net Taxable Gain |
|---|---|---|---|---|
| Sell BTC (<12 Months) | $10,000 AUD Cost | $25,000 AUD Sold | No Discount (0%) | $15,000 Taxable Gain |
| Sell ETH (>12 Months) | $20,000 AUD Cost | $60,000 AUD Sold | 50% Discount Applied | $20,000 Taxable Gain |
| Swap SOL for ETH (>12 Months) | $5,000 AUD Cost | $15,000 AUD Market Value | 50% Discount Applied | $5,000 Taxable Gain |
| Staking Yield Rewards | $0 Initial Cost | $3,500 AUD Received | Ordinary Income (100%) | $3,500 Ordinary Income |
3. The Mathematics of Crypto Capital Gains & Discounting
Net Taxable Crypto Capital Gain (CGT_net) for disposal proceeds (P_disp), AUD cost basis (C_base), and eligible 50% discount multiplier (Disc = 0.50) is:
Example Calculation ($20,000 ETH Purchased, Sold 14 Months Later for $60,000):
- Gross Capital Gain: $60,000 - $20,000 = $40,000 gross gain.
- 50% CGT Discount Applied (Held >12 months): $40,000 × 50% = $20,000 net taxable gain.
- Income Tax Payable @ 39% Marginal Rate: $20,000 × 39% = $7,800.00 tax due.

Frequently Asked Questions (FAQ)
How is cryptocurrency taxed by the ATO in Australia?
The ATO treats cryptocurrency as property and a Capital Gains Tax (CGT) asset (NOT money or foreign currency). Every disposal event (selling for AUD, trading crypto for crypto, spending crypto on goods/services, or converting to stablecoins) triggers a CGT event.
Does swapping one cryptocurrency for another trigger a taxable CGT event?
YES! Swapping BTC for ETH or converting altcoins into stablecoins (USDT/USDC) is a reportable CGT event. Capital gain or loss is calculated based on the AUD market value of the disposed crypto at the exact moment of the trade.
How are staking rewards, airdrops, and mining income taxed?
Staking rewards, DeFi yield interest, mining rewards, and airdrops are treated as ordinary assessable income at their AUD market value when received. When you later sell those tokens, the initial AUD value becomes your cost basis for CGT.
Can I claim the 50% CGT discount on crypto gains?
Yes! Australian individual tax residents who hold a cryptocurrency asset for more than 12 months before disposal can reduce their net capital gain on that asset by 50%.
How does the ATO track cryptocurrency transactions?
The ATO operates an automated Crypto Data Matching Protocol, obtaining transaction data directly from registered Australian digital currency exchanges (CoinSpot, Independent Reserve, Binance Australia, Swyftx) linked to your TFN.
