Crypto DeFi & Staking Tax Calculator Australia

Australian crypto investors don't just buy and hold — they stake, lend, farm liquidity, claim airdrops and bridge across chains. Each of these has a different ATO treatment, and the wrong category can mean paying tax twice (or missing income that triggers an audit). This estimator splits each scenario into the right bucket: ordinary income at receipt, capital gain on disposal, or not a CGT event at all.

Aligned with TR 2024/D1 (staking), TD 2014/26 + 2022 ATO update (airdrops), TD 2024/D consultation (wrapping/bridging) and the 50% CGT discount in s115-25 ITAA 1997.

Why DeFi tax is harder than buy-and-hold crypto

Plain spot trading is well-trodden CGT territory: each disposal is one event, FIFO parcels track cost base, the 50% discount applies if held over 12 months. DeFi shatters that simplicity in five ways:

• Income vs capital — staking rewards and lending interest are ordinary income, not CGT events. They get taxed at your full marginal rate with no 50% discount.
• Two layers of tax — staking creates income at receipt and a future CGT event when you sell the staked tokens. The receipt value becomes the cost base, so you don't double-tax, but you do file two events per cohort.
• LP deposits dispose your underlyings — when you deposit ETH/USDC into a pool, the ATO treats that as a sale of ETH and USDC at market value. If they appreciated since you bought them, that's a CGT event you owe tax on, even though you never "sold" anything.
• Airdrops have two categories — established tokens are income; brand-new initial allocations are $0 cost base (no income at receipt, but full proceeds are taxed when you eventually sell).
• Wraps and bridges sit in a grey zone — ATO's December 2023 draft TD 2024/D accepts no-CGT for wraps that preserve beneficial ownership, but cross-chain bridges that swap the asset are still a CGT event under the conservative reading.

How the calculator allocates losses to preserve the 50% discount

When you have a mix of capital gains and capital losses in a year, the order in which you offset them changes your final tax bill. The ATO accepts (as taxpayer-friendly) that losses should be applied to non-discountable gains first, leaving as much of the discount-eligible gain intact as possible. The math: a $1,000 loss applied against a non-discount gain saves you $1,000 of taxable income; applied against a discount gain it would only save $500 (because the discount halves it anyway). This calculator follows that ordering automatically.

What this calculator does NOT do

• It doesn't pull AUD prices from a price feed — you supply the AUD value at receipt / disposal. For a full transaction-level calculator with FIFO parcels and CSV import, use the Crypto Tax Calculator.
• It doesn't model NFT royalties or play-to-earn rewards (different ATO treatment again).
• It doesn't handle GST on yield-as-a-service or business-trader treatment (where crypto is on revenue account, not capital).
