Cryptocurrency and CGT: helping clients report digital assets
How capital gains tax applies to cryptocurrency, the events that trigger a tax outcome, and why record-keeping is the hardest part of getting crypto returns right.
Cryptocurrency has moved from the fringe into ordinary client returns, and with it comes a tax treatment that many clients do not fully grasp. The common misconception is that crypto is only taxed when converted back to dollars. In reality, a range of events can trigger a capital gains tax outcome, and the record-keeping required to report them accurately is where most of the difficulty lies.
How crypto is generally taxed
For most individual investors, cryptocurrency is treated as a capital gains tax asset. That means a disposal can trigger a capital gain or loss, calculated as the difference between what the asset was worth on disposal and its cost base. Where an asset has been held for the required period, a CGT discount may apply. Crypto held as part of a business, or used in certain ways, can be treated differently, so the client's circumstances matter.
The tax treatment of crypto assets and the events that trigger a CGT outcome are explained by the ATO, and because the ATO receives data from exchanges, unreported disposals are increasingly likely to be noticed.
The events clients miss
The surprise for many clients is how many actions count as a disposal. It is not just selling crypto for dollars.
- Trading one cryptocurrency for another is a disposal of the first.
- Spending crypto to buy goods or services is a disposal.
- Gifting crypto can trigger a CGT event.
Each of these can produce a gain or loss even though the client never saw any Australian dollars. Explaining this early prevents an unwelcome surprise at tax time.
Record-keeping is the real challenge
The hardest part of a crypto return is almost always the records. A client active across several exchanges and wallets may have hundreds of transactions, each needing a value in Australian dollars at the time and a cost base to match against disposals. Reconstructing this after the fact is painful, which is why encouraging clients to keep or export their transaction history as they go is so valuable.
Bring structure to a messy area
Because crypto reporting depends so heavily on data, the clients who hold it deserve a dedicated step in their return process. In Finye you can flag clients with crypto holdings and attach a specific document request and review step to their return jobs, prompting the team to collect complete transaction records and check the CGT calculations before lodging. Treating crypto as a known complexity rather than a last-minute discovery keeps these returns accurate. You can see how firms structure return checklists in Finye's guides.
Capital losses and the discount
Not every crypto disposal produces a gain, and the losses matter too. A capital loss on crypto can generally be used against capital gains, including gains on other assets, which makes accurate loss reporting genuinely valuable to the client rather than just a compliance formality. The holding period also matters, since an asset held long enough may qualify for the CGT discount on any gain. Both points reward keeping a clear record of acquisition dates and cost bases across every parcel the client holds.
Advise clearly and document the position
Clients value plain guidance here, because the rules are genuinely unfamiliar to them. Explaining which of their activities are taxable, what records you need, and how the calculation works turns anxiety into confidence. As with any area of judgement, documenting the basis of the reporting position protects everyone if questions arise later. Crypto is not going away, and the practices that build a clear, repeatable process for it now will find these returns far less daunting than those that treat each one as a novelty.
