DeFi Tax in Australia: What the ATO Wants to Know

The ATO's Position on DeFi

The Australian Taxation Office has issued guidance on crypto since 2014, and updated its position on DeFi specifically. The core principle: if you receive something of value, it's a taxable event.

This applies to staking rewards, lending interest, LP fees, and airdrops. It doesn't matter that it's on a blockchain — the ATO sees it as income.

What Gets Taxed and How

Staking and Lending Yield

When you receive staking rewards (stETH rebase, jitoSOL appreciation, Aave interest accrual) or lending interest, these are treated as ordinary income at the time you receive them.

The taxable amount is the AUD value of the tokens at the moment you receive them.

If you later sell those tokens for more than their income inclusion price, the gain is a capital gain. If you hold for 12+ months, the 50% CGT discount applies to the capital gain portion.

Example: - You receive 0.01 ETH as lending interest when ETH = $5,000 AUD. Income: $50. - Six months later you sell that 0.01 ETH for $75. Capital gain: $25 (discount not applicable — held under 12 months). - Total tax: assessed on $50 income + $25 capital gain.

LP Positions

This is where it gets complex. The ATO's position is that:

1. Entering an LP position = a disposal of both tokens (CGT event)
2. Swap fees received = ordinary income
3. Exiting the LP position = a disposal of the tokens you receive back

In practice, this means every time you enter and exit an LP, you're crystallising capital gains or losses on both assets.

The 12-Month CGT Discount

If you hold an asset for more than 12 months before disposal, you only pay CGT on 50% of the gain. This is one of the most valuable tax strategies for DeFi investors:

• Hold ETH/SOL/BTC for 12+ months before selling
• Use lending yield (stETH, etc.) rather than active trading to generate income
• Consider tax lot timing when deciding which positions to unwind

The Data-Matching Problem

The ATO runs data-matching programs with Australian exchanges (CoinSpot, Independent Reserve, Coinbase AU, etc.). If you've used an Australian exchange and received more than $10,000 in crypto, the ATO likely has your records.

On-chain DeFi transactions are harder for them to track, but not impossible. Blockchain analytics firms sell services to tax authorities globally. Assume your on-chain activity is not private.

What You Need to Track

For every financial year: - All crypto received (staking, lending, airdrops) — date, AUD value - All disposals (sales, LP entries/exits, token swaps) — date, AUD value in, AUD value out - Opening and closing portfolio value in AUD

The simplest way to do this: connect all your wallets to Koinly from the start and let it classify transactions automatically. Review and correct its classifications — it gets most things right but sometimes misclassifies DeFi interactions.

The Honest Summary

DeFi yield is taxable in Australia. The ATO is not lenient on crypto. The best strategy is meticulous record-keeping from the start and a tax accountant familiar with crypto for complex situations.

The 12-month CGT discount is real and worth planning around. Ordinary income from yield cannot be avoided — it's taxed when earned.
