Understanding IRS Crypto Audit Triggers

With the explosive growth of cryptocurrencies like Bitcoin, Ethereum, and countless altcoins, the IRS has become increasingly focused on ensuring that digital asset transactions are accurately reported. In the beginning the common myth was that cryptocurrency transactions weren’t reportable because they weren’t fiat currency.   That changed on March 25, 2014, with the issuance of IRS notice 2014-21.  It was a very short document and declared cryptocurrency to be treated as property.  I won’t go into all this meant for cryptocurrency here.  Suffice it to say that crypto transactions are treated more like stock transactions than money.

For the many investors, traders, or enthusiasts diving into crypto, the IRS is especially interested in these transactions making handling them very complex. But what exactly happens in an audit for cryptocurrency transactions — and what can be done?

The IRS is Paying Attention

In recent years, the IRS has ramped up enforcement efforts related to cryptocurrency. One clear sign of this is the inclusion of a question about digital assets right on the front page of Form 1040:

"At any time during [the tax year], did you receive, sell, exchange, or otherwise dispose of any digital asset?"

Answering “yes” flags the return for potential scrutiny. The IRS uses data analysis, blockchain tracing tools, and even subpoenas to crypto exchanges to identify unreported or underreported crypto income. If discrepancies are found, an audit often follows.

What Triggers a Crypto Audit?

Several scenarios can trigger an IRS audit related to cryptocurrency:

  • Large or frequent transactions with no matching income reported.

  • Missing or inconsistent reporting on capital gains from crypto sales.

  • Transfers between wallets or exchanges that raise red flags.

  • Failure to when a 1099 form is received from a crypto exchange.

Even honest mistakes can lead to an audit — which makes proper reporting crucial.

What Happens During the Audit?

If selected for an audit, the IRS will typically send a notice requesting more information. Here's what they might ask for:

  • Records of all cryptocurrency transactions.

  • Wallet addresses, exchange account statements, and transaction logs.

  • Documentation showing how gains, losses, or income are calculated.

The taxpayer is expected to demonstrate the accuracy of your tax filings, and discrepancies may lead to back taxes, penalties, and interest — or even criminal charges in severe cases.

How Enrolled Agents Can Help

A cryptocurrency audit can be highly technical and stressful. That’s where Enrolled Agents (EAs) from Books, Taxes & More, become essential.

Enrolled Agents are federally licensed tax practitioners who specialize in IRS matters. When facing a crypto audit, EAs can:

  • Help organize and interpret blockchain transaction data.

  • Advocate on behalf of the client in communications with the IRS.

  • Minimize potential penalties and negotiate settlements if needed.

  • Guide our clients through the Voluntary Disclosure Program if prior returns were incorrect.

With their deep understanding of tax law and the complexities of digital assets, Enrolled Agents are uniquely qualified to represent taxpayers in crypto-related IRS issues.  Steve at BTM has spent a great deal of time learning about crypto and how to help clients stay compliant with US tax law. 

Final Thoughts

As cryptocurrency becomes more mainstream, so does IRS enforcement. Whether a casual investor or an active trader, keeping accurate records and reporting crypto activity is essential. If you find yourself under audit, don’t panic — reach out to an Enrolled Agent who understands the intersection of tax regulations and blockchain technology.

Being proactive and prepared can make all the difference when facing IRS scrutiny over cryptocurrency transactions.
