Crypto CGT Tripwires: Australian Guide 2025
Crypto assets can trigger CGT tripwires in Australia whenever there is a CGT event under the Income Tax Assessment Act 1997 (ITAA 1997), most commonly when a taxpayer disposes of a crypto asset (including swapping one token for another), uses crypto to buy goods or services, gifts crypto, or otherwise changes beneficial ownership. From an Australian accounting practice perspective, the most frequent “gotchas” arise because clients assume CGT only happens when converting to AUD, whereas the ATO treats many crypto-to-crypto and “everyday use” transactions as disposals that crystallise a capital gain or capital loss.
Featured Answer: Crypto CGT tripwires are triggered when a client’s actions amount to a CGT event, including selling crypto for AUD, swapping tokens, spending crypto, gifting it, transferring beneficial ownership, or engaging in DeFi arrangements that change rights and ownership. The ATO expects taxpayers to calculate gains in AUD at the time of each taxable event, maintain contemporaneous records, and correctly distinguish between capital account (CGT) and revenue account (trading or business income), with errors often leading to understated income and penalties.
What does the ATO mean by “crypto asset” for CGT purposes?
For CGT, the ATO treats most crypto as a CGT asset, and disposals are generally dealt with under Part 3-1 and Part 3-3 of ITAA 1997. The ATO’s public guidance is clear that crypto is not “money” for Australian tax purposes in most cases, and that CGT applies to disposals in the same way it applies to other CGT assets.- Held on capital account: CGT applies; discount may apply if held at least 12 months and the taxpayer is an eligible individual/trust.
- Held on revenue account (trading/business): Gains are generally ordinary income; CGT discount is not relevant; different timing and deduction rules can apply.
ATO reference (guidance): ATO “Crypto assets and tax” and “Capital gains tax and crypto assets” webpages (current ATO public advice as of December 2025).
When does crypto trigger a CGT event in Australia?
A CGT event is triggered when there is a disposal or other legislated event affecting ownership or rights. The most common is CGT event A1 (disposal of a CGT asset) under ITAA 1997 s104-10.- Selling crypto for AUD: Disposal occurs at the time of sale (contract/time of transaction).
- Swapping crypto for crypto: Disposal of the asset given up, acquisition of the new asset at market value in AUD at that time.
- Using crypto to buy goods/services: Disposal of crypto; the “proceeds” are the market value of what is received.
- Gifting crypto: Disposal at market value (even if no money changes hands).
- Transferring crypto between people/entities: If beneficial ownership changes, CGT event may occur (even if it looks like an internal transfer).
- Wrapping/bridging tokens (chain migrations): May be a disposal if the arrangement changes the asset held or rights attached.
- Ceasing Australian residency / becoming non-resident: Potential deemed disposal rules can apply to CGT assets (subject to exclusions and choices).
- Loss/theft (including rug pulls): Not automatically a deduction; may require a CGT event such as cancellation, surrender, or other event depending on facts and evidence.
Is “crypto-to-crypto” the biggest CGT tripwire?
Yes. Crypto-to-crypto swaps are one of the most material CGT tripwires because clients often execute many swaps and incorrectly assume tax only applies when “cashing out” to AUD.- Each swap is typically a separate CGT calculation.
- Cost base tracking must be performed per parcel (date, quantity, fees, AUD value at time).
- Gas fees and exchange fees must be considered for cost base/reduced cost base depending on the facts.
- A client buys Token A, swaps into Token B multiple times during a bull run, and only later converts a small amount to AUD.
- The client reports only the AUD conversion.
- The ATO expects CGT outcomes for each intermediate swap, potentially producing a significantly higher net gain than reported.
How does spending crypto create a “hidden disposal”?
Spending crypto is a disposal because the client is giving up a CGT asset to acquire something else. The capital proceeds are the market value (in AUD) of what they receive (goods/services) at the time of the transaction.- A client pays for a laptop using ETH.
- Even though no AUD hits a bank account, the client has disposed of ETH.
- The gain/loss is calculated as: AUD market value at time of purchase minus cost base of the ETH units disposed of (including relevant fees).
ATO guidance aligns with this approach: “Using crypto to pay for goods or services is a disposal.”
When do DeFi activities trigger CGT tripwires?
DeFi is a CGT minefield because it frequently changes legal and beneficial ownership, rights, and entitlements. The ATO’s position is facts-and-circumstances driven, but tripwires commonly arise where tokens are exchanged, rights are replaced, or arrangements are economically similar to disposals.- Staking rewards: May be ordinary income at receipt (depending on facts), and later CGT on disposal of the reward tokens.
- Liquidity pool (LP) tokens: Contributing assets and receiving LP tokens can be treated as a swap (disposal of contributed tokens, acquisition of LP token).
- Yield farming: Multiple disposals can occur as tokens move between protocols and are swapped for reward tokens.
- Lending/borrowing: Wrapping, collateralisation, liquidation events, or receiving different tokens can trigger disposals.
- Token rebases: Can create complex cost base and timing outcomes depending on how the arrangement operates.
Practice warning: clients often cannot reconstruct the transaction chain without blockchain/exchange exports, and missing data typically leads to under-reporting.
- Airdrops: May be ordinary income if received as part of a profit-making scheme, business, or in connection with services; CGT applies on later disposal (cost base/timing depends on circumstances).
- Chain splits (forks): Tax outcomes can be complex; new tokens received may have specific cost base consequences, and later disposal triggers CGT.
- Staking rewards: Often treated similarly to other rewards—potentially ordinary income when derived, then CGT on disposal.
- Determine whether the activity is investment vs business/trading.
- Document the purpose, scale, repetition, and system of activities (relevant to characterisation).
ATO reference (guidance): ATO crypto webpages discuss airdrops, chain splits, staking and record-keeping expectations.
What are the key CGT “tripwire” record-keeping failures the ATO targets?
The ATO’s compliance focus on crypto record keeping is well established. A taxpayer must be able to substantiate cost base, proceeds, and transaction timing, generally in AUD, for each CGT event.- No AUD value at transaction time: Clients keep only token amounts, not the AUD equivalent at the time.
- Missing wallets/exchanges: Activity is fragmented across CEXs, DEXs, hardware wallets, and multiple chains.
- No fee tracking: Gas and trading fees omitted, distorting cost base and gains.
- Poor parcel matching methodology: Inconsistent approach to which units were disposed of.
- Lost access / lost keys: Client claims “lost” without evidence; ATO expects objective evidence and proper tax characterisation.
- Not reconciling to fiat flows: Bank statements may show deposits/withdrawals but not the internal on-chain activity that drives CGT.
ATO reference: Record keeping requirements derive from general substantiation principles and ATO guidance specific to crypto assets (expectations for transaction records, wallet addresses, exchange statements, dates, AUD values, and purpose).
How do you determine whether crypto is taxed under CGT or as trading income?
This is a recurring tripwire: mischaracterising a client as an “investor” when the facts indicate a business or profit-making scheme, or vice versa. The ATO looks to indicia such as intention, repetition, scale, sophistication, and system.- CGT (investment) indicators:
- Revenue account (trading/business) indicators:
- CGT regime: ITAA 1997 Parts 3-1 and 3-3 (including s102-5, s104-10).
- Ordinary income concepts: ITAA 1997 s6-5 (where applicable to trading/business-like activities).
Professional note: The correct characterisation must be evidenced in working papers. Where borderline, a defensible position requires contemporaneous documentation and consistency year-to-year.
How does the personal use asset exemption become a CGT trap?
Clients frequently assert the “personal use asset” exemption to avoid CGT. The ATO’s guidance indicates this exemption is narrow and depends on the asset being used mainly for personal use or enjoyment, not for investment, and is sensitive to factors like holding period and usage pattern.- Buying crypto and holding it hoping it rises, then spending it later (investment purpose dominates).
- Using stablecoins or major tokens as a store of value rather than an immediate medium of exchange.
- Claiming exemption without evidence of immediate personal consumption intent.
- Document the purpose at acquisition and the timeframe between acquisition and spending.
- If acquired primarily as an investment, the exemption is unlikely to apply.
ATO reference: The ATO discusses “personal use asset” considerations in its crypto CGT guidance.
- Moving crypto into another person’s wallet “for safekeeping”
- Sending to an exchange account in a different legal name/entity
- Transferring to a company/trust they control but that is a different taxpayer
In those cases, beneficial ownership may change, and CGT consequences can arise based on the substance of the arrangement.
- Individual transfers BTC to their family trust wallet address and later claims it was “still mine.”
- Without clear evidence and trust law consistency, the ATO may treat this as a change in ownership with CGT implications.
- Minting costs and platform fees affecting cost base
- Swapping NFTs for tokens (disposal)
- Royalty income (potentially ordinary income) vs capital proceeds on sale
- Multiple transactions across marketplaces without consolidated records
- Client mints an NFT, pays mint fee and gas, then swaps NFT for ETH, then swaps ETH into another token.
- This can involve multiple disposals with separate AUD valuations and cost base allocations.
How should an Australian practice quantify and document crypto CGT outcomes?
A defensible approach is systematic, reconciled, and evidenced. For professional-grade workpapers, the minimum expected standard is to reconcile activity sources and document methodology.- Identify all data sources: Exchanges, wallet addresses, on-chain explorers, DeFi platforms, fiat on/off-ramps.
- Confirm taxpayer and ownership: Individual vs company vs trust; identify beneficial owner(s).
- Extract transaction history: Ensure timestamps, transaction IDs, quantities, fees.
- Determine AUD market values: At the time of each CGT event using a consistent valuation source.
- Apply a consistent parcel method: Document the method used and apply consistently.
- Classify income vs capital: Staking/airdrops/fees—determine character and timing.
- Reconcile to bank statements: Confirm fiat deposits/withdrawals align with exchange records.
- Prepare workpapers and review exceptions: Missing prices, suspicious transfers, protocol migrations.
- Prepare CGT schedule and disclosures: Ensure alignment with the tax return labels and disclosure needs.
- Did you swap one crypto for another (including stablecoins)?
- Did you use crypto to buy anything (even small purchases)?
- Did you stake, earn rewards, or receive airdrops?
- Did you bridge tokens, wrap tokens, or migrate chains?
- Did you provide liquidity or receive LP tokens?
- Did you transfer crypto to or from any other person or entity?
- Did you lose access to a wallet, get hacked, or have tokens frozen?
How does MyLedger-style automation relate to crypto CGT work (practice efficiency note)?
Crypto CGT work is record-heavy and reconciliation-driven. In practice, the bottleneck is not only calculations, but also the end-to-end workflow: importing transaction data, reconciling to bank/exchange statements, producing consistent workpapers, and preparing compliant reporting outputs.- Automated reconciliation workflows: Reduces manual time spent matching bank flows and supporting statements.
- Working paper discipline: Consistent schedules and documented review points reduce risk.
- ATO-focused compliance workflow: Ensures due-date governance and lodgment readiness.
While crypto calculations may require specialist data tooling, the broader compliance workflow still benefits materially from automation in the practice stack.
