What to do if you receive IRS Letters 6174, 6174-A, 6173, or CP2000

Navigating the world of cryptocurrency taxes can be complex. If you've received a letter from the IRS regarding your crypto transactions, it's natural to feel a sense of anxiety. IRS Letters 6174, 6174-A, 6173, and CP2000 look scary at first, but there’s no need to panic – these are standard letters that hundreds of thousands of Americans receive each year.

This guide is designed to demystify these communications, explaining what each letter means, what is required of you, and how to take the correct course of action.

Why Did I Get a Letter? The IRS's Virtual Currency Compliance Campaign

The IRS is aware of the rapid growth in cryptocurrency adoption and is actively working to close the "tax gap,” the difference between taxes owed and taxes paid. As part of its Virtual Currency Compliance Campaign, the IRS is increasing its enforcement efforts to ensure taxpayers are accurately reporting their crypto gains, income, and trades. These letters are a key tool in this initiative, targeting taxpayers who may have failed to report or have misreported their transactions.

The IRS obtains information about taxpayer's crypto activities from various sources, including the new 1099-DA form issued by exchanges like Coinbase, Kraken, and Gemini, and through "John Doe" summonses that require exchanges to provide user data.

Detailed Breakdown of Each IRS Notice And How To Respond

Letter 6174: Informational Crypto Letter

This is the mildest of the crypto-related notices. It serves as a general reminder of your duty to report any cryptocurrency transactions.

What to do:

• Review your past tax filings to ensure all crypto activity was correctly reported.
• If everything is accurate, no further action is needed.
• If you find any discrepancies or omissions, you should file an amended return using Form 1040-X.

Letter 6174-A: Warning About Unreported Crypto

This letter is a step up from the 6174. It signals that the IRS has information indicating you have or had crypto, and they suspect you may have unreported transactions.

What to do:

• Carefully review your cryptocurrency transaction records and compare them against your submitted tax returns.
• If you've missed any taxable events, file an amended return using Form 1040-X.

Letter 6173: Compliance Enforcement Letter

Receiving a Letter 6173 is a serious matter. It means the IRS has strong evidence to believe you have not complied with tax laws regarding cryptocurrency and requires a response.

What to do:

• Immediately note the response deadline, which is typically 30 days. Missing this deadline is critical and can lead to further enforcement action.
• If you believe your return is accurate, you must send a signed confirmation to the IRS explaining your position.
• If your return is incorrect or you failed to file, you must file a corrected or delinquent return, including all necessary crypto forms like Form 8949 and Schedule D.
• Ignoring this letter is not an option and could lead to a formal audit.

CP2000 Notice: Explanation of Proposed Changes

A CP2000 notice is not exclusive to crypto, but it is frequently issued to crypto investors. It means there is a discrepancy between the income and transaction information reported to the IRS by third parties (like crypto exchanges) and the information you reported on your tax return.

What to do if you get a CP2000 for crypto:

• Pay close attention to the 30-day response deadline.
• Carefully review the proposed changes and compare them with your records to determine if the IRS is correct.
• If you agree with the notice, sign the response form and return it. You can pay the proposed amount to stop further interest accrual.
• If you disagree, do not sign the agreement. Instead, send a detailed explanation of why you disagree, along with supporting documentation. You should also request an appeal in your response to protect your rights.
• Consider using a crypto tax tool like Crypto Tax Calculator or consulting a CPA or Attorney to recalculate your gains and losses accurately.
