On 19 August 2026, the ATO issued Draft Taxation Determination TD 2026/D2, providing its first detailed guidance on the tax treatment of wrapping and unwrapping crypto through a smart contract. This guidance addresses a common assumption among crypto users that converting ETH to WETH, or changing WETH back to ETH, is simply a like-for-like conversion with no tax consequences.
However, that assumption is incorrect. Under the Australian Taxation Office’s (ATO’s) proposed view, both wrapping and unwrapping can trigger a capital gains tax event under Australian tax law. This is because the tax treatment depends on what happens to your ownership of the crypto, rather than your intention when making the transaction.
Therefore, even if you do not sell the crypto to another person and the wrapped token is designed to track the original asset’s value, transferring the crypto to a smart contract can still end your ownership of the original asset for Capital Gains Tax (CGT) purposes.
Key Takeaways
- Sending crypto into a wrapping contract counts as a disposal, not a neutral conversion.
- The wrapped token you receive is treated as a separate asset from the original crypto.
- Reversing the wrap later, by unwrapping, is a second, entirely separate taxable event.
- A wrapping arrangement can produce a gain or a loss, depending on price movement.
How Does The ATO Tax Wrapping And Unwrapping Crypto In Australia?
Wrapping and unwrapping tokens do not fit neatly into the CGT event that usually applies to crypto disposals. The ATO has had to reason through why that is, and the answer changes how both the wrapping step and the unwrapping step are taxed.
Tax On Wrapping A Crypto Asset
The moment you send your original crypto, such as ETH, to a wrapping contract, CGT event C2 happens. The capital proceeds from this event are the market value of the wrapped token you receive in return, which will usually match the market value of the original crypto at that exact time. Your capital gain or loss is calculated by comparing those proceeds against the cost base of the crypto you originally held.
Once you receive the wrapped token, it is treated as a new and separate CGT asset in its own right, distinct from the crypto you sent in. Its cost base is set at the market value of the original crypto at the time you wrapped it, which becomes the starting point for whatever happens to that wrapped token next.
Tax On Unwrapping A Crypto Asset
Unwrapping is a separate CGT event C2, not a continuation of the original wrapping event. It occurs when the wrapped token is burnt and the original crypto is released to you.
The capital proceeds are the market value of the crypto received at that time. Your gain or loss is the difference between these proceeds and the wrapped token’s cost base. The crypto you receive then becomes a new CGT asset, with a cost base equal to its market value when unwrapped.
Why Wrapping Tokens Trigger CGT Event C2 and Not A Simple Swap?
Most crypto disposals, such as selling or swapping one asset for another, trigger Capital Gains Tax (CGT) event A1, which requires a change of ownership from one entity to another. Wrapping does not fit that description, because there is no counterparty on the other side of the transaction.
You are not selling ETH to another person or business; you are sending it to an autonomous smart contract that simply locks it and mints a corresponding token in return. Because there is no other entity to whom ownership is transferred, the ATO’s position is that CGT event C2 applies instead. CGT event C2 covers situations where your ownership of an asset ends through abandonment, surrender, or release, rather than through a sale to someone else.
Once you send your original crypto to the wrapping contract’s address, you no longer control it through your private key, and your ownership of that specific asset is treated as having ended at that moment.
How To Calculate Tax On Wrapping Or Unwrapping Crypto In Australia?
As wrapping and unwrapping are treated as two independent CGT events, each one needs its own calculation, using its own cost base and its own capital proceeds.
Step 1: Calculate The Gain Or Loss On Wrapping
Compare the market value of the wrapped token you receive against the cost base of the original crypto you sent in.
Capital Gain or Loss (Wrapping) = Market Value Of Wrapped Token Received − Cost Base Of Original Crypto
Step 2: Set The Cost Base Of The Wrapped Token
The wrapped token’s cost base is fixed at the moment you receive it, using the same market value figure from Step 1.
Cost Base Of Wrapped Token = Market Value Of Original Crypto At Time Of Wrapping
Step 3: Calculate The Gain Or Loss On Unwrapping
When you later unwrap, compare the market value of the original crypto you receive back against the cost base of the wrapped token you are giving up.
Capital Gain or Loss (Unwrapping) = Market Value Of Crypto Received Back − Cost Base Of Wrapped Token
Step 4: Set The Cost Base Of The Newly Received Crypto
The crypto you receive back from unwrapping is a new asset, with its cost base fixed at its market value on the date of unwrapping, unrelated to any cost base that applied before you originally wrapped it.
Cost Base Of New Crypto = Market Value Of Crypto At Time Of Unwrapping
Step 5: Apply The CGT Discount, If Eligible
Each of these two events is assessed on its own holding period. If you held the original crypto for at least 12 months before wrapping it, that gain may qualify for the CGT discount. The wrapped token itself starts its own 12-month clock from scratch, so an unwrapping event will only qualify for the discount if the wrapped token itself was held for 12 months or more.
Discounted Gain = Capital Gain × 50% (individuals; assessed separately for each CGT event, based on that event’s own holding period)
How To Report Wrapping Or Unwrapping Crypto Tax In Australia?
Both events need to be reported as capital gains or losses, using the same section of your tax return that applies to any other crypto disposal.
Keep Separate Records For Each Event
Because wrapping and unwrapping are two independent CGT events, keep separate records for each one:
- The date and market value of the original crypto at the moment you wrapped it.
- The date and market value of the wrapped token at the moment you unwrapped it, if and when that happens.
- Any gas or network fees paid as part of either transaction, since these are treated separately from the CGT calculation itself.
Report both the wrapping event and the unwrapping event through the capital gains section of your tax return, the same way you would report any other crypto disposal.
Convert each event’s figures into Australian dollars at the relevant date, and apply the CGT discount separately to each event where the holding period allows it. If your combined gains or losses for the year exceed A$10,000, complete the capital gains tax schedule as well.
Note: TD 2026/D2, the ATO’s determination on this topic, is still in draft form and open for public comments till 2nd October 2026. The position described above reflects the Commissioner’s preliminary view, and while it is unlikely to change materially before finalisation, it is worth confirming the determination’s current status before relying on it for a specific return.
How Can KoinX Help With Wrapping Or Unwrapping Crypto Tax in Australia?
Tracking two separate cost bases through a wrapping and unwrapping cycle, especially across multiple wrapped assets, is exactly the kind of reconciliation that becomes error-prone by hand. KoinX connects with 800+ wallets, exchanges and blockchains, pulling, wrapping and unwrapping transactions into your transaction history automatically.
Multiple Accounting Methods
KoinX supports FIFO, LIFO, HIFO and Average Cost Basis, letting you choose the method that best matches how you track cost bases as they reset through successive wrapping and unwrapping events.
Complete Tax Report
The Complete Tax Report applies ATO rules directly to your transaction data, covering CGT, income, and portfolio balances in one place, giving you a single, consistent record across both the wrapping and unwrapping side of a DeFi position.
Before committing to a paid report, KoinX’s free crypto tax calculator for Australia gives a quick estimate of your capital gains position on crypto you have already wrapped, unwrapped, or otherwise disposed of.
If you use wrapping contracts as part of your DeFi activity, connecting your wallets to KoinX keeps every wrap and unwrap tied to its correct cost base automatically. Get started with KoinX, and turn a multi-step DeFi position into one clear, accurate capital gains record.
Wrapping and unwrapping are not the tax-neutral conversions they can appear to be. Each step is its own disposal under CGT event C2, with its own cost base and its own capital gain or loss, even though the wrapped token is built to track the original asset’s value exactly.
Since the cost base resets at every wrap and unwrap, the biggest risk here is losing track of which value applies to which step. Join KoinX today and keep each event’s date and market value tied to the right asset automatically, so a multi-step DeFi position stays reconciled without manual tracking.
Frequently Asked Questions
Does Wrapping ETH Into WETH Count As Selling My ETH?
Not in the ordinary sense of a sale, but yes for tax purposes. There is no buyer on the other side of the transaction; you are sending your ETH to a smart contract rather than to another person. The ATO still treats this as a disposal, under CGT event C2, because your ownership of the original ETH ends the moment you send it to the contract.
If I Wrap And Immediately Unwrap The Same Asset, Do I Still Owe Tax?
Potentially, yes, on each leg separately, even if the round trip feels like nothing happened. If the crypto’s market value moves between the wrapping moment and the unwrapping moment, even briefly, each event is assessed on its own, and a small gain or loss can arise on either or both steps.
Does The 12-Month CGT Discount Reset Every Time I Wrap Or Unwrap?
Yes. Because wrapping and unwrapping each create a new CGT asset with its own cost base, the 12-month holding period also resets at each step. A wrapped token only qualifies for the discount on unwrapping if you held that specific wrapped token for 12 months or more, regardless of how long you held the original crypto before wrapping it.
Are Gas Fees Included In The Capital Gain Or Loss Calculation For Wrapping?
Generally, no, not directly in the gain or loss figure itself. Network and gas fees paid to complete a wrapping or unwrapping transaction are treated separately from the CGT calculation on the crypto asset, though they may still be relevant to your overall cost base depending on how they were paid.
