Learn the consequences of crypto tax evasion in Australia and how to fix past mistakes before it’s too late.

Think the ATO won’t notice your unreported crypto trades? Think again. With new data-sharing rules and advanced tracking tools, the ATO has eyes on nearly every exchange, wallet, and transaction linked to Australian residents. That means skipping crypto reporting,  whether by mistake or on purpose, could land you in serious trouble.

In 2025, the ATO is cracking down harder than ever on crypto tax evasion. What might seem like a harmless omission could be treated as fraud or tax evasion, both of which come with heavy penalties, fines, and even jail time in extreme cases.

If you’ve missed declaring your crypto earnings, this guide is for you. We’ll walk you through what the ATO considers crypto tax evasion, the penalties involved, how to fix past mistakes, and what you can do to avoid trouble, before it’s too late.

Can the ATO Track Crypto Transactions?

Yes — and more closely than many investors realise. The ATO has developed a powerful data-matching program that allows it to track cryptocurrency transactions through exchanges, wallets, and service providers operating within and outside Australia.

Every crypto exchange that operates in Australia must register with AUSTRAC as a designated service provider (DSP). These exchanges are legally required to collect and share user data with government agencies, including the ATO. This means that if you’ve used any exchange that complies with AUSTRAC regulations, the ATO likely already has access to your transaction history, wallet addresses, and personal details.

The ATO’s data collection reaches as far back as 2014 and includes:

  • Full legal name and contact details
  • Wallet addresses and transaction records
  • Linked bank accounts and trading activity
  • IP addresses and identity verification documents

With this level of visibility, underreporting or ignoring crypto tax obligations is no longer an option.

What Is Considered Crypto Tax Evasion in Australia?

Not reporting your crypto activity isn’t just a minor mistake — it could be treated as tax evasion or even fraud, depending on your actions and intent. The Australian Taxation Office (ATO) is clear: investors must report all taxable crypto events, including capital gains, income from staking, airdrops, and more. 

Below, we break down how the ATO distinguishes between crypto tax evasion and crypto tax fraud — and why the difference matters.

Crypto Tax Evasion

Crypto tax evasion typically refers to any behaviour that results in the avoidance of tax. This could involve:

  • Omitting crypto income or gains from your tax return
  • Incorrectly classifying income as capital gains
  • Not reporting transactions made through decentralised platforms
  • Using offshore or unregistered exchanges to hide trades

Even if your omission wasn’t intentional, the ATO may still classify it as tax evasion if you cannot provide a credible explanation. For example, claiming you “didn’t know crypto was taxable” is not likely to hold up, especially with the ATO’s clear guidance on reporting obligations.

Crypto Tax Fraud

Tax fraud is more severe and involves knowingly making a false statement to reduce or avoid your tax liability. In crypto, this could include:

  • Submitting false values or forged records in your return
  • Claiming deductions or losses that never occurred
  • Tampering with wallet data or transaction logs
  • Falsifying the date or source of a crypto transaction

The key difference lies in intent. If you deliberately tried to mislead the ATO or knew the information was false when filing your return, your actions could be treated as fraud, a criminal offence that carries much harsher penalties than civil tax evasion.

Penalties for Crypto Tax Evasion in Australia

The ATO treats crypto tax evasion seriously — and so does the Australian legal system. Depending on whether your actions are considered negligent, careless, or fraudulent, the penalties can range from small fines to imprisonment. Below are the key categories of penalties you could face as a crypto investor.

Administrative Penalties

Administrative penalties are issued for unintentional errors like failing to report crypto income, lodging your return late, or omitting disposal events. These are civil penalties, not criminal charges, but they can still be expensive.

The ATO calculates these fines using penalty units, with each unit valued at $222 (as of 2025). The penalty you receive depends on how much tax was avoided and the severity of your behaviour. For example:

  • Failure to lodge on time can result in up to 5 penalty units (a fine of $1,110)
  • Failure to take reasonable care could attract higher penalties based on a statutory formula

While these penalties are less severe than criminal charges, repeated offences or large discrepancies increase your audit risk.

Criminal Offences and Tax Fraud

When tax evasion crosses into fraud, it becomes a criminal offence under the Criminal Code Act 1995. This applies if you deliberately submit false information, forge records, or conceal income with the intent to reduce your tax liability.

The most serious crypto tax fraud cases can result in:

  • Fines of up to 200 penalty units
  • Imprisonment for up to 10 years

The ATO may prosecute fraud cases in federal court, particularly when large sums are involved or when the behaviour appears systematic or intentional. These penalties are reserved for the most severe breaches, but they show how far the law can go when crypto tax fraud is proven.

ATO Discretion and Behavioural Assessment

Not all cases go straight to court. The ATO has the discretion to classify your behaviour based on three levels:

  • Failure to take reasonable care
  • Recklessness
  • Intentional disregard of tax law

The more deliberate your actions, the higher the penalty. However, the ATO may reduce penalties for cooperative behaviour, voluntary disclosure, or first-time offences. This behavioural model allows the ATO to match the penalty with the nature and intent behind the offence.

Understanding Voluntary Disclosure in Australia

If you’ve accidentally or knowingly skipped reporting your crypto income, you’re not alone — but ignoring it won’t make it go away. The good news is that the ATO offers a way to come clean without facing the harshest penalties.

It encourages taxpayers who’ve made mistakes to submit a voluntary disclosure. This allows you to correct errors, omissions, or misleading information in your previous tax returns. Voluntary disclosure is available whether your misreporting was intentional or unintentional. The key is to take action before the ATO contacts you or begins an audit.

What You Can Declare Through a Voluntary Disclosure?

You can use this process to declare:

  • Previously unreported crypto income (like airdrops or staking rewards)
  • Capital gains or losses you forgot to include
  • Misclassified income (e.g. reporting trading income as investment gains)
  • Mistakes in cost basis calculations or incorrect wallet reporting

The ATO views voluntary corrections as a sign of good faith, especially when they come before formal enforcement steps begin.

How Penalties Are Reduced With Early Action?

If you submit a voluntary disclosure before the ATO advises you of a review or audit, you may receive a penalty reduction of up to 80%. In many cases, you may only have to pay the tax owed plus interest. The earlier you act, the more leniency the ATO typically applies — especially for first-time disclosures or smaller discrepancies.

How to Fix Your Crypto Tax Returns With the ATO?

If you’ve missed reporting crypto transactions in previous tax years, correcting those errors can help you avoid penalties and stay compliant. Whether it’s an honest mistake or a forgotten transaction, the ATO offers tools and support to help you make things right. Here’s how to fix your past crypto tax returns step by step.

Amend Past Returns Using myGov or a Registered Tax Agent

You can amend a lodged tax return by signing into your myGov account and accessing the ATO’s ‘Income Tax’ section. Choose the relevant year and select “amend” to update the crypto-related details.

Alternatively, you can ask a registered tax agent to submit the amendment on your behalf. Make sure all figures reflect accurate capital gains, losses, or income values from your crypto transactions.

Declare Missed Crypto Transactions Accurately

Go back and identify any unreported crypto disposals, staking rewards, airdrops, or other forms of income. For each transaction, include:

  • The date of the event
  • The fair market value in AUD at that time
  • The cost base and any associated fees
  • The net gain or loss (if applicable)

It’s essential to base this data on verifiable records from exchanges, wallets, or CSV files.

Reach Out to the ATO for Help if You’re Unsure

If you’re not confident in fixing things on your own, the ATO provides help through online chat, phone support, and guidance articles. You can also request a private ruling if your situation involves unique circumstances. Seeking assistance is always better than submitting incorrect amendments, as it shows a genuine intent to comply with the law.

ATO Scam Warning for Crypto Investors

As crypto adoption grows, so do scams targeting unsuspecting investors. The ATO has issued multiple alerts about fraudsters impersonating government officials to exploit taxpayers. If you’ve received suspicious messages claiming you’re under investigation for crypto tax evasion, you’re not alone. Here’s what to look out for — and how to stay safe.

Common Crypto Scam Tactics in Australia

Scammers often pose as ATO representatives using emails, phone calls, or SMS messages. Their goal is to trick you into revealing personal data, wallet details, or crypto account access. These messages may:

  • Claim you owe unpaid crypto tax
  • Threaten legal action or arrest if you don’t respond
  • Urge you to log in using a suspicious link
  • Request you connect your wallet for “review” or “verification

How to Identify a Fake ATO Message?

The real ATO will never:

  • Ask you to click login links sent via SMS or email
  • Request access to your crypto wallet or exchange account
  • Demand urgent payments via crypto, gift cards, or prepaid debit cards
  • Send threatening messages without prior written communication

If you receive such contact, do not respond or click any links. Instead, report the incident to the ATO’s Scam Reporting Service.

Frequently Asked Questions

Can I Go to Jail for Not Reporting Crypto in Australia?

Yes, in serious cases of deliberate fraud, the ATO can pursue criminal charges. This applies if you’ve knowingly submitted false information or intentionally hidden crypto assets. The maximum penalty includes up to 10 years of imprisonment under the Criminal Code Act. However, most first-time or minor offences are addressed through administrative fines rather than criminal prosecution.

Will the ATO Audit Me If I Use Overseas Exchanges?

Possibly. The ATO’s data-sharing agreements with global exchanges and financial regulators allow them to access records from many international platforms. If you’ve traded crypto through overseas exchanges, it’s still your responsibility to report these activities in your tax return. Not doing so could increase your risk of audit or penalty.

What’s the Difference Between Tax Evasion and a Simple Mistake?

The difference lies in intent. A simple mistake might be forgetting to report a transaction due to misunderstanding. Tax evasion involves knowingly hiding or misrepresenting your financial activity to avoid tax. The ATO assesses the intent and behaviour behind the omission to determine whether it was a genuine oversight or deliberate non-compliance.

How Far Back Can the ATO Audit My Crypto Transactions?

The ATO typically reviews records from the past 4 years, but there’s no limit in cases involving fraud or evasion. If you’ve failed to report crypto deliberately, the ATO can examine your data dating as far back as 2014. Keeping detailed records for all financial years ensures you’re prepared in case of a review.

Can I Claim Past Losses If I Didn’t Report Them Earlier?

You cannot claim unreported capital losses unless they’re included in a valid tax return. If you missed reporting them, you’ll need to amend previous returns. Once correctly lodged, these losses can be carried forward indefinitely to offset future capital gains. Accurate reporting ensures you retain full use of your available tax benefits.
