The Australian Taxation Office (ATO) has released draft guidance proposing how capital gains tax (CGT) applies when crypto investors wrap and unwrap digital assets using smart contracts. The draft determination focuses on a common decentralised finance (DeFi) activity that many crypto users have traditionally viewed as an administrative or technical step rather than a taxable event.
If finalised in its current form, the guidance in TD 2026/D2 could have significant implications for Australian crypto investors who interact with DeFi protocols, liquidity pools, lending platforms, and decentralised exchanges.
While the draft determination is not yet final, it provides a strong indication of the ATO’s current thinking and gives investors an opportunity to assess how their activities may be treated for tax purposes moving forward.

What Is Crypto Wrapping?
Wrapping is a process that allows one crypto asset to be represented by another tokenised version that is compatible with specific blockchain protocols or applications.
A common crypto wrapping example involves Ether (ETH). Because many DeFi protocols are designed to work with ERC-20 tokens, users often convert ETH into Wrapped Ether (WETH). The wrapped token is intended to maintain a one-to-one value relationship with the original crypto asset while enabling broader functionality within decentralised applications.
Under the arrangement described by the ATO:
- The original crypto asset is transferred to a smart contract.
- The smart contract locks that asset.
- A corresponding wrapped token is minted and issued to the user.
- The wrapped asset is then used within DeFi protocols.
- When the user wants to reverse the process, the wrapped token is returned and burned.
- The original asset is released back to the user’s wallet.
The ATO’s Proposed Position in TD 2026/D2
The central issue addressed in the draft determination is whether wrapping and unwrapping crypto assets constitutes a taxable event for CGT purposes.
The ATO’s preliminary view is that it does.
According to the draft guidance, when a crypto asset is transferred into a wrapping smart contract, ownership of the original CGT asset ends. The ATO considers that the original asset is effectively abandoned, surrendered, or released when it is sent to the smart contract. As a result, CGT event C2 is proposed to occur at that point.
The wrapped token received in exchange is treated as a separate CGT asset, even though it may represent equivalent value to the original asset.
This approach differs from the view held by some participants in the crypto industry who see wrapping as a technical conversion rather than a disposal of an asset.
Why the Distinction Matters
The difference between treating wrapped and original assets as the same asset or separate assets has important tax consequences.
If the ATO’s view is adopted:
- Wrapping a crypto asset may trigger a capital gain or capital loss.
- The market value of the wrapped token received becomes the capital proceeds.
- The wrapped asset receives a new cost base.
- Unwrapping may trigger another CGT event.
- The asset returned from unwrapping is treated as a new CGT asset with its own cost base.
- This means investors could potentially generate multiple taxable events without ever converting their holdings into fiat currency.
Example: Wrapping Ether
The draft determination provides an illustrative example.
An investor purchases five ETH for $10,000. Several years later, those ETH are worth $30,000. The investor wraps the ETH to obtain WETH for use in a DeFi application.
Under the ATO’s proposed approach:
- CGT event C2 occurs when the ETH is wrapped.
- Capital proceeds are $30,000, being the market value of the WETH received.
- The investor’s cost base remains $10,000.
- A capital gain of $20,000 arises at the time of wrapping.
- Even though the investor continues to hold economic exposure to the same underlying value, the transaction may create a taxable gain.
Example: Unwrapping the Asset
The draft guidance also considers what happens when the wrapped asset is later redeemed.
Using the same example, the investor later unwraps the WETH and receives ETH worth $28,000.
According to the proposed treatment:
- CGT event C2 occurs again when the WETH is burned.
- Capital proceeds are $28,000, reflecting the value of the ETH received.
- The WETH has a cost base of $30,000.
- A capital loss of $2,000 arises.
- The newly received ETH obtains a cost base of $28,000.
This demonstrates how both wrapping and unwrapping could independently trigger CGT consequences.
The ATO’s Reasoning
A key aspect of the draft determination is the ATO’s view of crypto asset ownership.
The ATO considers a crypto asset to be defined by the specific ownership rights associated with the wallet address and private key controlling that asset. Once the original asset is transferred to a wrapping contract, the taxpayer no longer has control over that specific asset.
Although an equivalent wrapped token is created and received, the ATO argues this represents a different asset rather than a continuation of the original holding.
The draft determination also rejects several alternative interpretations, including:
- The view that ownership of the original asset continues while it remains locked.
- The argument that wrapping merely changes the form of an existing asset.
- The suggestion that replacement asset rollover relief should apply.
- The possibility that other CGT events more appropriately apply to the transaction.
What This Could Mean for DeFi Users
For active DeFi participants, the practical impact could be substantial.
Many DeFi strategies involve multiple wrapping, staking, bridging, lending, and token conversion activities. If each relevant transaction triggers a CGT event, investors may face increased record-keeping requirements and more complex tax reporting obligations.
Investors who have historically treated wrapping activities as non-taxable may wish to review their transaction histories and consider how the final guidance could affect their positions.
Particular attention may be required where assets have experienced significant value growth before being wrapped, as this is where unrealised gains could potentially become taxable under the ATO’s proposed approach.
It’s Still Draft Guidance
Importantly, the determination remains in draft form and is currently open for public consultation.
The ATO has invited submissions from stakeholders before finalising its position. The proposed determination is intended to apply both before and after its eventual issue date if finalised in its current form.
That means the final outcome could influence the treatment of both historical and future transactions.
What Should Investors Do Now?
While the draft determination is not yet binding, it provides useful insight into how the ATO is approaching increasingly sophisticated crypto and DeFi activities.
If you have wrapped or unwrapped crypto assets, now may be a good time to:
Review Your Transaction Records
Ensure you have accurate records of wallet transactions, market values, timestamps, and related activity.
Assess Potential CGT Exposure
Consider whether historical wrapping transactions could create capital gains or losses under the proposed framework.
Monitor Further Developments
The final determination may differ from the draft position following industry consultation and submissions.
