DeFi Tax in Australia: Liquidity Pools, Yield Farming, and What the ATO Says

🧱 The foundation: crypto-to-crypto is a CGT event🔗

Every time you exchange one crypto asset for another, you trigger a CGT event. This applies whether you're swapping on a decentralised exchange, depositing into a liquidity pool, or wrapping a token, if you're giving up one crypto asset and receiving something different, a CGT event has occurred. You cannot net capital losses against other income, only against capital gains, in the same year or carried forward.

💧 Liquidity pools, the most misunderstood area🔗

Depositing into a liquidity pool is a CGT event, the capital proceeds equal the market value of what you receive in return, another crypto asset or a right. In one of the ATO's own examples, depositing 1 ETH with a cost base of $2 in return for 20 pool tokens worth $20 crystallises an $18 capital gain, even though no AUD ever changed hands.

Withdrawing is a separate CGT event, this time on the LP tokens or rights themselves, capital proceeds equal the market value of whatever you withdraw.

🎯 The essential: Impermanent loss isn't a separate deduction. It's simply reflected in the capital gain or loss calculation when you withdraw, if the pool returns less than your LP token cost base, that shows up as a smaller gain or an outright loss, not as a standalone claim.

🌾 Yield farming rewards🔗

Periodic rewards from a DeFi platform, governance tokens, fee-share tokens, or similar, are assessable income at the AUD market value on receipt, taxed similarly to interest income. That value becomes the cost base of the reward tokens, so when you later sell them, only the gain above that already-declared value is a further CGT event. It's the same double tax event that applies to crypto staking rewards, income first, CGT later.

One genuine grey area: protocols that auto-compound rewards without tokens ever landing in your wallet. The ATO's guidance talks about rewards you "receive", but hasn't specifically addressed what counts as receipt when reinvestment happens automatically on your behalf. Treat this as an open question and get advice if it applies to you.

🎁 Wrapped tokens🔗

Wrapping or unwrapping a token, like ETH to wETH, is a CGT event. The ATO's position, reinforced by private ruling guidance, is that a wrapped token is a distinct CGT asset from the native token, so exchanging between them is a disposal.

Liquid staking tokens, assets that behave differently from simple wrapped tokens because they accrue value over time and aren't always redeemable 1:1, sit in a genuine grey zone the ATO hasn't specifically addressed.

🖼️ NFTs🔗

For most investors buying and selling NFTs, standard CGT rules apply, calculate the gain or loss on disposal, with the 50% discount available if held 12+ months. For creators running an NFT business, proceeds from the initial sale and ongoing royalties are ordinary income, not a capital gain. NFT fractionalisation and NFT-backed loans remain areas the ATO hasn't specifically addressed.

🎯 The 50% discount, harder to access than it looks🔗

Every CGT event creates a new asset with a new acquisition date, so the 12-month clock resets every time. Depositing into a pool disposes of your original crypto and acquires LP tokens, whose clock starts on the day of deposit, not the day you bought the underlying crypto. Withdrawing resets it again. Active DeFi participants, anyone regularly moving between pools or rotating positions, will almost never hold a single asset for 12 consecutive months, making the discount largely theoretical for that style of use.

❓ What the ATO has not yet clarified🔗

In the interest of being honest rather than confidently wrong: the ATO has not specifically addressed auto-compounding yield (does reinvestment count as receipt?), liquid staking token treatment, DAO governance token distributions, cross-chain bridge transactions, or the interaction between DeFi income treatment and loss deductibility. These are genuine gaps, not areas where the answer just requires reading more carefully. Watch the ATO's published guidance for updates, and treat any of these scenarios as worth a conversation with a specialist tax agent before relying on an assumption.
