Crypto tax in Sydney: the plain-English version
Every swap is a disposal. Every disposal is reportable. The ATO already has your exchange data. Here is what that actually means for a Sydney holder, including the discount change arriving in July 2027.

We are not tax agents and this is not tax advice. Crypto tax in Australia is genuinely complex, the rules are changing, and your circumstances matter. Use this page to understand the shape of the problem, then take it to a registered tax agent. The ATO publishes detailed guidance on crypto asset transactions, and the Tax Practitioners Board register lets you verify that anyone advising you is actually registered.
How the ATO sees crypto
The starting point that explains everything else: in Australia, crypto is not money. The ATO treats crypto assets as property, and for most individuals as a capital gains tax asset. That single classification generates almost every consequence people find surprising.
Because it is property rather than currency, disposing of it is a CGT event — the same way selling shares or an investment property is. Because it is property, swapping Bitcoin for Ethereum is not "moving money between accounts"; it is disposing of one asset and acquiring another, with a gain or loss crystallised on the first. And because it is property, buying a coffee with it is a disposal too, which is why our spending guide spends so long on the record-keeping burden.
There is a narrow exception for personal use assets, but it is far narrower than people hope — it generally requires acquiring and using crypto in a short window specifically to buy personal goods, and the ATO applies it restrictively. Do not plan around it.
What counts as a disposal
This is the section worth reading twice, because the list is longer than most people expect.
| What you did | CGT event? | Notes |
|---|---|---|
| Bought crypto with AUD | No | Sets your cost base — record it |
| Held it while the price moved | No | Unrealised gains are not taxed |
| Sold crypto for AUD | Yes | Proceeds minus cost base |
| Swapped one coin for another | Yes | Disposal of the first asset at market value |
| Spent crypto on goods or services | Yes | Including a crypto-funded card purchase |
| Gifted crypto to someone | Yes | Treated as a disposal at market value |
| Moved coins between your own wallets | No | Keep records to prove it was your wallet |
| Received staking or airdrop rewards | Income | Ordinary income at receipt, then CGT later |
The row that catches the most people is the crypto-to-crypto swap. Someone who traded actively through a bull market, never withdrew a dollar to their bank account, and finished the year holding less value than they started with can still owe tax — because each profitable swap along the way was a realised gain, and the later losses may fall in a different income year. This is not a theoretical scenario; it happened to a lot of Australians after 2021.
Keep it simple from day one One licensed account with exportable trade history is far easier to reconcile than five apps and a spreadsheet.
Open an accountThe 12-month discount — and what replaces it in 2027
Currently, an individual who holds a CGT asset for at least twelve months before disposing of it can apply a 50% CGT discount to the gain. Hold for eleven months and you declare the full gain; hold for twelve months and a day and you declare half. On a substantial position that is a very large difference, and it is why timing a sale around the twelve-month mark is one of the few genuinely simple tax optimisations available to Australian crypto holders.
This is changing. Legislation passed in June 2026 replaces the 50% discount with a cost-base indexation model plus a minimum tax on real gains, effective from 1 July 2027. Transitional rules mean gains that accrued before that date on assets you already hold keep the existing discount treatment, so long-term holders are not retrospectively worse off on the value built up so far.
What that means practically depends heavily on your holding period, your marginal rate and your inflation assumptions, which is precisely the kind of question a registered tax agent should model for you rather than something to work out from a website. If you hold a significant position, this is worth a conversation before the changeover rather than after.
When crypto is income rather than capital
Not everything is CGT. Several situations produce ordinary income, taxed at your marginal rate with no discount available.
Staking rewards, interest-style yield and most airdrops are generally ordinary income at their Australian dollar value on the day you receive them. That value then becomes the cost base for a future CGT event when you dispose of the reward. Being paid in crypto for work or services is income at market value on receipt. Mining may be income, and if conducted as a business, a different set of rules applies again.
The distinction that generates the most argument is investor versus trader. An investor holds assets and reports gains under the CGT regime with access to the discount. A trader carries on a business of trading, reports profits as ordinary income with no discount, and treats holdings as trading stock. The ATO looks at volume, frequency, sophistication, intention and whether the activity is organised in a businesslike way. You do not get to simply choose the more favourable classification, and getting it wrong in either direction is expensive.

Records: what to keep, and for how long
The ATO requires records to be kept for five years from the later of when you prepared or obtained them and when the transaction was completed. But five years is a floor, not a plan. If you buy Bitcoin today and sell it in 2039, you will need today's cost base at that point — and the exchange you used may not exist any more.
For every transaction, keep the date, the value in Australian dollars at the time, what the transaction was for, who the other party was (a wallet address is sufficient), and any fees. Practically, that means exchange trade confirmations, deposit and withdrawal records, wallet addresses you control, and receipts from machines or counters.
Two habits make this painless. First, export your full trade history from every platform monthly and save it somewhere permanent — not in the exchange account, which is exactly what disappears when a platform fails. Second, if you use more than one platform or wallet, use crypto tax software that aggregates them. Several products handle Australian rules and ATO reporting formats specifically, and the annual cost is trivial against the hours of reconstruction it saves.
If your records are already incomplete — a common situation for anyone who started before 2018 — do not let that stop you filing. Reconstruct what you can from bank statements, archived emails and on-chain history, document your methodology, and get a registered tax agent to help. The ATO expects a reasonable, documented approach, not perfection.
- Per transaction, record
- Date, AUD value, purpose, counterparty address, fees
- Export monthly
- From every exchange, stored outside the exchange
- Use software
- Aggregators that handle ATO formats save days of work
- Incomplete history?
- Reconstruct, document the method, get an agent involved
The three questions that make or break a Sydney crypto return
After several years of reader correspondence around tax time, the same three issues account for most of the distress. Missing cost bases from platforms that no longer exist. Unrecorded crypto-to-crypto swaps that the taxpayer genuinely did not know were taxable. And transfers between their own wallets that tax software misread as disposals, inflating apparent gains dramatically.
All three are record-keeping problems rather than tax-law problems, and all three are cheap to prevent and expensive to fix. The single highest-value habit for a new Australian crypto holder is not choosing the right coin — it is exporting a CSV every month and labelling your own wallet addresses as you create them.
ATO data matching: assume they already know
This is not a system you can quietly opt out of.
Exchange data flows in
The ATO collects identity and transaction data from Australian digital currency exchanges under its data-matching program and reconciles it against lodged returns.
Prompts and letters
Many Australians receive a pre-fill prompt or a letter noting crypto activity. Receiving one is not an accusation, but ignoring it is a poor idea.
Voluntary disclosure
If you have under-reported in a previous year, a voluntary disclosure through a registered tax agent generally produces a far better outcome than waiting to be found.
Finding a crypto accountant in Sydney
Sydney has a real depth of accountants who handle crypto properly, and a larger number who will tell you they do. The difference matters, because a general practitioner learning on your return will charge you for the education and may still get the investor-versus-trader question wrong.
Verify registration first. Anyone charging a fee to prepare your return must be registered with the Tax Practitioners Board, and the TPB register is public and searchable. That is a two-minute check with the same logic as the AUSTRAC check we recommend for exchanges.
Then ask specific questions. How many crypto clients did they handle last year? Which tax software do they work with, and will they accept an export from the aggregator you use? How do they approach the investor versus trader distinction, and what evidence do they look at? Have they handled an SMSF holding crypto, if that is relevant to you? A practitioner who genuinely does this work answers all of that comfortably and without hedging.
Expect to pay more than a standard individual return. Expect to do preparation work yourself — a good agent will want clean exports, not a shoebox. And engage them before June, not in the last week of October, when every agent in the city is at capacity.
- Check the Tax Practitioners Board register before engaging anyone who charges for tax advice.
- Export your full trade history from every platform, monthly, and store it outside the platform.
- Label your own wallet addresses so transfers are not misread as disposals.
- If you hold a large position, get advice on the July 2027 changeover before it arrives.
Frequently asked questions
Do I pay tax on crypto in Australia if I do not cash out to dollars?
Yes, in most cases. Swapping one crypto asset for another is a disposal of the first asset and a CGT event, even though no Australian dollars were involved. So is spending crypto on goods or services, and so is gifting it. Only buying and holding is not a taxable event.
How much tax will I pay on crypto gains in Sydney?
Capital gains are added to your assessable income and taxed at your marginal rate, so the answer depends entirely on your total income. Individuals who held the asset more than 12 months currently get a 50% CGT discount on the gain. There is no separate flat "crypto tax rate" in Australia.
What changes for crypto tax on 1 July 2027?
Legislation passed in June 2026 replaces the 50% CGT discount with a cost-base indexation model plus a minimum tax on real gains, taking effect 1 July 2027. Under transitional rules, gains that accrued before that date on assets you already hold keep the existing 50% discount treatment. Talk to a registered tax agent about what this means for your specific holdings.
How long do I need to keep crypto records for the ATO?
Five years from the later of the date you prepared or obtained the records, and the date you completed the transactions they relate to. In practice, because a cost base can be needed many years after purchase, most accountants tell clients to keep crypto records indefinitely.
Does the ATO know about my crypto?
Very likely. The ATO runs a data-matching program that collects information from Australian digital currency exchanges, including identity details and transaction data, and matches it against lodged returns. Undeclared disposals on Australian platforms are among the easiest discrepancies for the ATO to detect.
Can I claim a loss on crypto?
Capital losses can offset capital gains in the same year, and unused losses can be carried forward indefinitely to offset future capital gains. They cannot be used to reduce ordinary income such as salary. Losses from a genuine theft or scam may be claimable in some circumstances — this is exactly the situation where you should get advice from a registered tax agent rather than guessing.
