A CoinJar tax file usually comes down to one question: can you explain how each asset moved from purchase to disposal?
CoinJar reports can help with that work, but they should not be treated as a finished tax calculation. A Purchase and Sales Report may show the trades made inside CoinJar. A Deposits and Withdrawals Report may show crypto moving in or out. An account statement may help with balances. Each report answers a different part of the tax question.
For Australian tax, the ATO does not tax the report; it taxes the transaction. For an individual investor, a sale or crypto-to-crypto conversion will generally create a CGT event. A transfer to a wallet you beneficially own is not a disposal if ownership does not change, although crypto used to pay a network or withdrawal fee is separately disposed of. CoinJar Bundles add another layer because every underlying asset is treated as separately held and rebalancing transactions can trigger tax events.
The safest approach is to rebuild the CoinJar activity in order: purchases, incoming transfers, conversions, Bundle movements, sales, outgoing transfers, and final balances. Once the chain makes sense, the numbers for myTax or your tax agent become much easier to support.
Key takeaways
- CoinJar tax reports help you review account activity, but the final tax result still needs a proper calculation.
- The Purchase and Sales Report is different from the Deposits and Withdrawals Report, and both may matter.
- For an individual investor, selling crypto, converting one crypto asset into another, spending crypto, or gifting crypto will generally create a CGT event.
- A deposit into CoinJar may need an older purchase record from another platform or wallet.
- A withdrawal to a wallet you beneficially own is not a CGT disposal if ownership remains unchanged, but the transfer evidence and any crypto fee disposal must be recorded.
- CoinJar Bundle assets are treated as separately held, and rebalancing triggers tax events for the underlying transactions rather than one tax-neutral Bundle adjustment.
- cryptact can help organise CoinJar activity with the rest of the taxpayer’s exchange and wallet history.

Build the CoinJar tax trail before calculating gains
CoinJar records make more sense when you read them as a chain rather than a summary.
Start with the asset that was sold, converted, spent, or transferred. Then trace backwards. Where did it come from? Was it bought on CoinJar, deposited from another exchange, received from another person, or created through a Bundle movement?
Then trace forwards. Did the asset leave CoinJar for a wallet you own? Was it sold for Australian dollars? Was it converted into another crypto asset? Did a Bundle rebalance move part of the holding?
That order matters because a single CoinJar account can contain both taxable and non-taxable movements. A buy creates cost base. A sale may create a gain or loss. A conversion may create a disposal. A withdrawal to your own wallet may only be a movement between accounts.
The tax file should show the route clearly enough that someone else can follow it without guessing.
Which CoinJar records to collect
CoinJar allows users to export trading and transaction history for tax purposes. The exact file you need depends on how you used the account during the Australian income year.
For most users, the main records are:
- Purchase and Sales Report
- Deposits and Withdrawals Report
- account statements
- CoinJar Exchange trading history, where used
- older reports for assets sold during the year
- wallet records outside CoinJar
- bank records linked to deposits and withdrawals
- previous-year crypto tax reports
Use CSV files where possible. A PDF may help with review, but CSV files usually work better for tax software, spreadsheets, and accountant checks.
Do not only download the report for the year of sale. If you sold an asset in 2025–26 that you bought in an earlier year, the older purchase record still matters. Without it, the gain may look larger than it really is.
The date range should match the Australian income year from 1 July to 30 June. For assets held across multiple years, keep the older files in the same tax folder.
How the Purchase and Sales Report fits into CGT
The Purchase and Sales Report is the part of the CoinJar file most closely connected to CGT. It helps identify buys, sells, and conversions made through CoinJar.
For tax purposes, each disposal needs enough information to calculate the result. That usually means:
- asset disposed of
- date of disposal
- quantity
- proceeds in Australian dollars
- acquisition history
- cost base
- fees
- resulting capital gain or loss
A sale for Australian dollars is the easiest disposal to recognise. A conversion can be easier to miss.
If you convert BTC into ETH, you have not simply moved crypto inside the account. For an individual investor, you will generally have disposed of the BTC and acquired ETH. Calculate the BTC disposal using fair market value in Australian dollars from a reputable and consistently applied source, and create a separate ETH acquisition record using that value for the next disposal.
Do not wait for cash to reach your bank before checking CGT. These rules generally apply where crypto is held as an investment. A limited personal use asset exception may apply where crypto costing less than A$10,000 was acquired and used mainly to buy personal goods or services within a short period. Spending investment crypto does not create the exception; losses on a personal use asset are disregarded, and a payment gateway, prepaid crypto card, or bill-payment intermediary does not by itself establish direct personal use. Crypto-to-crypto conversions can matter even when no Australian dollars leave CoinJar.
Why deposits and withdrawals can change the answer
The Deposits and Withdrawals Report often explains the transactions that the trading report cannot.
A deposit into CoinJar may show that crypto arrived, but it does not always show how the taxpayer first acquired it. The asset may have been bought on another exchange, moved from a hardware wallet, received as a gift, or transferred from an older account.
That missing history affects the cost base.
A withdrawal has the opposite problem. CoinJar may show that crypto left the account, but the tax treatment depends on where it went. Moving crypto to a wallet you beneficially own does not trigger a CGT disposal if ownership does not change. A joint or third-party wallet may change beneficial ownership, while a transfer to another person, payment for goods or services, or movement connected with a swap can create a disposal.
A useful review asks:
- Does the deposit match an older purchase record?
- Does the withdrawal go to a wallet the taxpayer owns?
- Does the transaction hash match the receiving wallet record?
- Did the transfer happen before a later sale on another platform?
- Did a fee qualify as an incidental cost, and was any crypto used to pay that fee separately disposed of?
The report gives the movement. The supporting record gives the meaning.
CoinJar Bundles and rebalancing
CoinJar Bundles need their own check because they can hide several asset movements behind one product experience.
A Bundle lets a user buy a group of crypto assets together, but the ATO position reflected in the review treats each underlying asset as separately and individually held. Allocate the original Bundle cost among those assets using a reasonable and supportable method. A later sale, unbundling, or rebalance must then be analysed asset by asset.
Rebalancing deserves special attention. A CoinJar Bundle rebalance triggers tax events for the underlying transactions: each asset disposed of must be calculated separately using its allocated cost base and Australian-dollar proceeds. Do not treat the Bundle adjustment as one harmless or tax-neutral account update.
The tax file should show:
- when the Bundle was bought
- which assets sat inside it
- the cost allocated to each asset
- whether any rebalance occurred
- which assets were sold or adjusted
- the value used for each movement
- what remained after the rebalance
If the report does not make the Bundle activity clear, review the detailed account history before finalising the return. Even a small rebalance can contain multiple underlying disposals and acquisitions that must be recorded separately.
CoinJar tax calculation example
Assume you bought 0.2 BTC through CoinJar for A$9,000 and paid A$90 in fees. Your cost base is A$9,090.
Later, you converted that 0.2 BTC into ETH when the BTC was worth A$12,500.
For an individual investor, the BTC conversion will generally count as a disposal. The calculation would look like this:
- capital proceeds: A$12,500
- cost base: A$9,090
- capital gain: A$3,410
The ETH then starts with its own acquisition record at A$12,500, adjusted for eligible incidental costs. If any fee is paid in crypto, that fee payment also creates a separate disposal record for the fee asset at its Australian-dollar market value.
If you later sell the ETH, you do not reuse the original BTC cost base directly. You calculate the ETH disposal using the ETH acquisition record created at the conversion stage.
This is where many CoinJar tax files go wrong. The user remembers buying crypto once, but the account history may contain later conversions that reset the asset being held. Each disposal needs its own calculation.
Preparing CoinJar figures for myTax
CoinJar does not lodge your Australian tax return. Once the CoinJar records have been reviewed, the final figures still need to go into myTax or to your tax agent.
For an individual investor, CoinJar sales, conversions, spending, and gifts generally belong in the Capital gains or losses section of myTax. The final working should show:
- total capital proceeds
- cost bases
- current-year capital gains
- current-year capital losses
- any CGT discount
- carried-forward capital losses, where relevant
- final net capital gain
An Australian individual who held an eligible crypto asset for at least 12 months may qualify for the 50% CGT discount. Exclude both the acquisition day and disposal day when testing the period. Apply current-year capital losses first, then carried-forward capital losses, and only then apply the discount to the remaining eligible gain.
Crypto income needs a separate review. Staking rewards are generally ordinary income when received, and an established-token airdrop received in the ordinary course of investing may also be ordinary income. Referral amounts, cashback, promotional credits, and other rewards require classification from their nature and circumstances. Where a receipt is taxable income, its receipt-time Australian-dollar market value becomes the starting cost base for a later disposal.
Business activity also needs separate treatment. Frequency alone does not decide the category. The overall facts include commercial purpose, organisation, repetition, business-like systems, and capital scale. A person operating through a company, using an ABN for the activity, systematically market-making, or running an organised profit-seeking enterprise should obtain professional advice before applying individual-investor CGT treatment.
Before lodging, compare the final tax report with CoinJar exports, bank records, other exchange files, wallet histories, and the previous year’s closing balances. A return built only from one CoinJar report may miss the acquisition or disposal that happened somewhere else.
Records to keep after filing
The ATO expects crypto records to explain what happened, when it happened, what the transaction was worth in Australian dollars, and which parties or wallets were involved where relevant.
For CoinJar activity, keep:
- Purchase and Sales Reports
- Deposits and Withdrawals Reports
- account statements
- CoinJar Exchange reports, where used
- Bundle records and rebalance details
- transaction hashes
- wallet addresses
- notes proving wallet ownership
- bank records linked to AUD deposits and withdrawals
- reports from other exchanges
- previous-year crypto tax reports
- fee records
- Australian-dollar valuation records
- final CGT and income calculations
- copies of the lodged return or tax agent workpapers
Keep these records for the period required by the ATO. As a general rule, retain them for five years from the latest relevant date, including when the record was prepared or obtained, when the transaction was completed, or when the CGT event occurred. Keep acquisition and valuation evidence longer where it remains relevant to a later disposal, return, or review period.
The ATO can receive crypto-related data from service providers and compare it with tax returns. Good records make it easier to explain why the return differs from a simple account summary.
How cryptact helps
CoinJar reports answer important parts of the tax question, but many users also have assets moving through other exchanges and wallets. cryptact helps organise those separate records into one transaction history.
That becomes useful when a CoinJar sale depends on an older purchase made elsewhere, or when a CoinJar withdrawal later connects to a disposal on another platform. It can also help identify missing acquisition records, separate transfers from taxable disposals, and keep conversion history visible.
cryptact supports CoinJar file upload and API connection. The result still needs review, especially where Bundle activity, older transactions, or external wallet movements need extra context.
The aim is not to make CoinJar the centre of the return. The aim is to place CoinJar activity correctly inside the wider crypto tax file.
Conclusion
Calculating CoinJar crypto taxes in Australia starts with the right reports, but the reports only work when they connect to the full asset history. The Purchase and Sales Report helps with trades and conversions. The Deposits and Withdrawals Report explains movement into and out of the account. Bundle records may need extra review because rebalancing can create disposals.
Sales and conversions can create capital gains or losses. Transfers to your own wallet need matching evidence. Deposits from outside CoinJar need original cost records. Income-type receipts should not be mixed into the CGT calculation without review.
cryptact helps organise CoinJar records alongside other exchange and wallet activity so the final figures for myTax or a tax agent can be built from a connected transaction trail rather than one isolated report.
