Discover what happens if you don’t report cryptocurrency on taxes, including fines, audits, and potential legal trouble.

If you’re wondering what happens if you don’t report cryptocurrency on taxes, you’re not alone. Many crypto investors assume the IRS can’t track every trade or wallet, but that’s no longer true. The IRS now treats crypto just like property, and even small trades, swaps, or rewards can create taxable events that need to be reported.

Skipping this reporting can bring more trouble than most people expect. From surprise audits to late-payment interest and even fraud penalties, the IRS has several tools to enforce crypto tax compliance. In this guide, we’ll break down the real risks, how the IRS tracks your activity, and what you can do to fix past mistakes safely.

Overview:

  • Crypto tax evasion includes evasion of assessment and evasion of payment.
  • Assessment evasion hides income before tax calculation; payment evasion avoids paying assessed tax.
  • Penalties range from 20% to 75%, plus interest and prison risks.
  • IRS detects evasion using 1099 data, blockchain tracing, and wallet monitoring.
  • Not reporting crypto triggers audits, penalties, notices, or criminal prosecution.

About Crypto Tax Evasion In The USA

Types of Crypto Tax Evasion in the USA

Crypto tax evasion is a serious concern in the USA, with the IRS categorizing it into two primary types: 

  • Evasion of assessment.
  • Evasion of payment. 

Each type carries distinct penalties and risks. Understanding these categories can help you comply with tax laws and avoid severe consequences.

Avoiding paying the tax bill that the IRS already assessed.

Common Examples

  • Under-reporting gains to lower taxable income 
  • Ignoring staking, mining, or DeFi income 
  • Not reporting business income received in crypto 
  • Not reporting wages paid or received in crypto
  • Moving crypto to untraceable wallets 
  • Transferring funds to foreign exchanges without KYC 
  • Liquidating assets secretly to avoid payment 
  • Hiding crypto holdings after receiving an IRS notice

When It Happens?

How the IRS Detects It?

What Happens If You Don't Report Cryptocurrency On Taxes?

Not reporting your crypto activity can lead to financial penalties and, in serious cases, legal trouble. The IRS treats crypto transactions the same way it treats property transactions, so every sale, trade, or conversion needs to be reported. Ignoring this can trigger multiple consequences.

Can the IRS Track My Crypto Transactions?

How Does the IRS Tracks Cryptocurrencies in the USA

Yes, the IRS can track your crypto activity through several data sources. Exchanges, blockchain records, and reporting forms all give the IRS clear visibility into your transactions. Here are the main ways they monitor crypto activity:

  • Exchange Data Sharing: Most major exchanges collect KYC information when you create an account. These platforms share user data with the IRS through compliance programs and reporting rules. This makes it easy for the IRS to match your identity with your trading history.
  • John Doe Summons: The IRS can issue a John Doe summons to compel exchanges to provide information about users who may be hiding income. This tool has helped the IRS uncover unreported crypto activity from thousands of taxpayers. It is commonly used when the IRS suspects widespread underreporting.
  • IRS 1099 Forms: When a crypto exchange sends you a 1099 form, the IRS receives the same form automatically. This creates a direct record of your trading activity, rewards, and income. If your return does not match the data sent to the IRS, it can trigger an audit.
  • Blockchain Transparency: Blockchain transactions are recorded on public ledgers, making them traceable. IRS agents now use blockchain analytics tools to link wallet addresses to real individuals. “Anonymous” wallets are no longer as private as people assume.
  • Ongoing Crypto Tax Investigations: The IRS actively investigates cases involving unreported crypto income. Hundreds of cases are reviewed each year to identify patterns of evasion. These investigations show that the IRS takes crypto reporting seriously and continues to expand enforcement.

How Can You Submit A Rectified Return?

Steps To Submit a Rectified Return

If you missed reporting some of your crypto activity, you can still fix it. The IRS allows you to correct past mistakes instead of ignoring them. Follow these steps to clean up your crypto taxes and reduce the risk of penalties.

Step 1: Recalculate Your Crypto Tax Liability

Start by working out how much tax you actually owe on your crypto.

  • Gather all your trades, swaps, income, and transfers.
  • Use a crypto tax tool like KoinX to import your data and calculate gains, losses, and income.
  • Review the numbers carefully so your updated return is accurate.

Step 2: Prepare an Amended Return with Form 1040X

If you already filed your tax return, you must amend it.

  • Use IRS Form 1040X to correct the original return.
  • Add all previously missed crypto income, gains, or losses.
  • Attach updated forms and schedules, such as Form 8949 or Schedule D, if they change.

After filing, the IRS usually takes several weeks to process amended returns.

Step 3: File the Amended Return and Monitor the Status

Once Form 1040X is complete:

  • Submit it electronically if eligible, or mail it as per IRS instructions.
  • Keep copies of everything you send, including crypto reports from KoinX.
  • Watch for IRS notices or updates about your amended return.

Step 4: Consider Voluntary Disclosure with Form 14457 (For Serious Cases)

If you knowingly failed to report large amounts of crypto or did this over several years, consider a more formal route.

  • The IRS Voluntary Disclosure Program uses Form 14457.
  • This form lets you come forward, disclose past non-compliance, and agree to pay all taxes, interest, and civil penalties.
  • In many cases, this can help you avoid criminal prosecution, as long as the IRS has not already started an investigation.

Step 5: Stay Compliant Going Forward

Once you fix past returns, focus on staying compliant.

  • Use tools like KoinX each year to track and calculate your crypto taxes.
  • Report all crypto income, trades, and disposals in your annual return.
  • Keep proper records so you never have to worry about missed reporting again.

Frequently Asked Questions

Is Crypto-to-Crypto Trade Taxable in the USA?

Yes. When you trade one cryptocurrency for another in the USA, it counts as a taxable event. You must report the fair market value of the crypto you received at the time of the trade. Keeping detailed records of each swap makes it easier to report your gains or losses correctly.

How Long Do I Have to Hold Crypto to Avoid Taxes?

You cannot avoid taxes completely, but holding crypto for more than a year can lower the tax rate on your gains. Selling within a year means your profit is taxed at your normal income tax rate. Holding for a year or longer qualifies for long-term capital gains tax, which is usually lower.

What Triggers an IRS Audit for Crypto?

Several factors can trigger an IRS audit for crypto transactions. Common triggers include:

  • Missing or incorrect reporting of crypto income, gains, or trades
  • Large or unusual transaction amounts compared to previous years
  • Trading on offshore exchanges that do not share data with the IRS
  • Using privacy coins or wallets that appear designed to hide activity
  • Receiving 1099 forms from exchanges that do not match what you reported
  • Moving large amounts of crypto between wallets without clear records
  • Patterns that suggest possible tax evasion or underreporting

How Far Back Can the IRS Audit You?

The IRS normally audits tax returns from the last 3 years. If they find a major error, they can look back up to six years. In cases involving fraud or large amounts of unreported income, there is no time limit. Reporting every transaction correctly helps you avoid these issues.
