What Is IRS Form 4564? Why Crypto Tax Reporting Feels So Confused Right Now

By Clinton Donnelly, CEO, Founder | CryptoTaxAudit

A new IRS audit form is circulating in crypto investigations. It lists over a hundred exchanges, DeFi platforms, and wallets. During an audit, the agent hands it to you and asks which ones you've used. A lot of crypto investors are calling this a perjury trap. It's not, if you know what to write.

And while Form 4564 is causing concern in crypto circles, a separate problem is showing up at tax time. Millions of taxpayers received 1099-DA forms from their exchanges. Now they're trying to reconcile those numbers with crypto tax software, and the figures don't match. There are reasons for that. The IRS created both problems.

Key Takeaways

IRS Form 4564 is an Information Document Request used during crypto audits. It includes a list of more than 100 exchanges, DeFi platforms, and wallets. Audited taxpayers are legally required to indicate which platforms they have used.
The form is not a perjury trap if you include a knowledge qualifier in your response. Signing under "best of my knowledge" allows you to correct omissions later without facing perjury charges.
1099-DA forms issued by exchanges use different cost basis rules than those required of taxpayers. Exchange reporting is subject to broker rules under IRC Section 6045. Taxpayer reporting follows IRC Section 1012. The two sets of rules do not produce the same numbers.
The correct method for 1099-DAs on your return is to subtract the exchange-reported gains and replace them with your crypto tax software output. This is called an adjustment and is reported on Form 8949.
Tax preparers familiar with 1099-B forms are unprepared for 1099-DA. The 1099-DA does not provide the summary totals that 1099-B forms do, leaving preparers to perform manual calculations they weren't expecting.
IRS auditors will face the same confusion as taxpayers. The 1099-DA data is inconsistent with proper tax reporting requirements, which means erroneous audit results are likely.

What Is IRS Form 4564?

IRS Form 4564 is an Information Document Request. Agents use it to formally request records from taxpayers during an examination. In crypto audits, a version of this form has been circulated that lists over 100 exchanges, DeFi protocols, and wallet providers.

The audited taxpayer is asked to indicate which platforms they have used. This is a legal requirement. The IRS can compel this disclosure, including under oath in a deposition setting.

The form created significant concern when it became widely known. Privacy-focused members of the crypto community flagged it as overreach. But IRS agents have broad authority to request financial records during an audit, and this form falls within that authority.

The concern most taxpayers should focus on is not whether the IRS can ask. It can. The question is how to respond without creating a legal liability.

Is Form 4564 a Perjury Trap?

The form is only a perjury trap if you sign it without a qualifying statement. The correct approach is to answer under the phrase "to the best of my knowledge." That language is meaningful.

If it turns out later that you forgot an account, the qualifier gives you room to correct the record. A taxpayer might recall years after a transaction that they held funds on an exchange like BitConnect, or had assets stuck on a platform they couldn't access. The "best of my knowledge" language means an incomplete answer at the time of signing is not automatically perjury.

This is a standard legal qualifier used across many types of sworn statements. It reflects the reality that memory is imperfect, especially over multi-year trading histories across dozens of platforms.

Answer the form. Use the knowledge qualifier. That is the way through it.

What Is a 1099-DA and Why Don't the Numbers Match?

The 1099-DA is a new information return. Exchanges began issuing it for the 2024 tax year. It reports digital asset transactions, proceeds, and in some cases cost basis directly to the IRS and to the taxpayer.

The problem is that the numbers on a 1099-DA frequently do not match what a taxpayer's crypto tax software calculates. This is not a software error. It is a structural problem built into how 1099-DAs are generated.

Exchanges report under IRC Section 6045, which governs broker reporting. Taxpayers are required to calculate gains under IRC Section 1012, which governs cost basis identification.

The rules are different. The instructions in each code section differ. That means the same set of transactions can produce different numbers depending on which set of rules you apply.

The IRS created a situation where its own information returns do not align with the tax rules taxpayers must follow.

How to Report 1099-DA on Your Tax Return

Every 1099-DA you receive must be accounted for on your tax return. When a return is filed electronically, the metadata records which information returns were considered. The IRS needs to see that you addressed each one.

The correct method is an adjustment on Form 8949. You subtract the gains reported on the 1099-DA, then enter the accurate figures from your crypto tax software. Form 8949 rolls up to Schedule D and functions as a detailed listing of all your digital asset sales.

Form 8949 does not require every individual trade to be itemized on the form itself. Summary reporting is acceptable as long as the underlying detail is available in the event of an audit. The full picture requires reporting total proceeds and total cost basis across all transactions, whether they occurred on centralized exchanges, decentralized protocols, or peer-to-peer.

The adjustment approach lets you satisfy the IRS's expectation that you accounted for the 1099-DA while reporting your gains accurately under the correct legal standard.

Why the 1099-DA Confuses Tax Preparers

Tax preparers who handle stock portfolios are familiar with the 1099-B. That form provides clean summary totals at the top: short-term trades, long-term trades, covered transactions, and uncovered transactions. A preparer can identify what to enter on the return quickly.

The 1099-DA does not work that way. It provides transaction-level detail without a usable summary. Preparers must manually add up figures and work backward to understand how the numbers were calculated.

For someone charging a few hundred dollars to prepare a return, that level of manual effort is not commercially viable.

The result is that some preparers are declining to handle crypto returns at all. That outcome runs directly counter to the IRS's stated goal of improving tax compliance. When preparers exit, more taxpayers file incorrectly or not at all.

The IRS acquired a large volume of transaction data without providing the tools or format that would allow professionals to use it efficiently.

The Cost Basis Problem: Why Exchange Reports Differ from Your Return

The mismatch between 1099-DA figures and crypto tax software output has a specific cause.
Consider this scenario:

A taxpayer purchases Ethereum two years ago and moves it to a private wallet. Later, they buy more Ethereum on Coinbase. Then they transfer the older Ethereum from the private wallet back onto Coinbase and sell some of it. Coinbase does not know the cost basis of the transferred-in Ethereum. It only knows that assets arrived from an external source.

Simple View of the Problem

Buy ETH (2 years ago) → Move to private wallet → Send back to Coinbase → Sell

Coinbase sees: Unknown source → Short-term
You report: Known cost basis → Long-term

Under the broker reporting rules, Coinbase must report the transferred-in Ethereum as having an unknown cost basis and treat it as short-term.

Under IRC Section 1012, the taxpayer must report based on actual acquisition dates and actual cost basis. That older Ethereum is a long-term holding. Selling it is a long-term capital gain, which is taxed at a lower rate.

The 1099-DA will show a short-term gain. The correct tax return should show a long-term gain.

When a taxpayer tries to reconcile the two, the numbers will not match. The discrepancy is not a mistake. It is a consequence of two different legal frameworks being applied to the same transactions.

What Happens When IRS Auditors Encounter 1099-DA Data?

IRS revenue agents assigned to crypto audits will face the same structural confusion as taxpayers. A 1099-DA does not map cleanly to a completed tax return.

An agent trying to verify whether a return is accurate will need to untangle the same cost basis mismatches, platform transfers, and rule conflicts that the taxpayer dealt with during filing.

Agents who cannot reconcile the data face two choices: issue erroneous audit findings based on flawed comparisons, or pass on the examination entirely.

Neither outcome serves the IRS's compliance goals. Data without clarity is not enforcement. The 1099-DA created new reporting volume without a corresponding gain in auditor capacity or comprehension.

Until the IRS reconciles the broker reporting rules with the taxpayer reporting rules, the confusion will persist at every stage of the process.

Frequently Asked Questions About IRS Form 4564 and 1099-DA

Q: What is IRS Form 4564 used for in crypto audits?

A: Form 4564 is an Information Document Request. In crypto examinations, it lists over 100 exchanges, DeFi platforms, and wallet providers. The audited taxpayer must indicate which ones they have used. Failure to respond can result in legal consequences because the IRS has authority to compel this disclosure.

Q: Can I get in legal trouble for leaving an exchange off my Form 4564 response?

A: Only if you sign without a qualifying statement. Signing under "to the best of my knowledge" protects you if you later remember an account you overlooked. This qualifier is legally meaningful and is the standard approach for responding to IRS document requests of this type.

Q: Why does my 1099-DA show different numbers than my crypto tax software?

A: Exchanges report under IRC Section 6045, the broker reporting rules. Taxpayers calculate gains under IRC Section 1012. The two sets of rules produce different cost basis figures, especially for assets that were transferred between wallets before being sold. The software is not wrong. The 1099-DA is applying a different legal standard.

Q: Do I have to report my 1099-DA if the numbers are wrong?

A: You must account for every 1099-DA on your tax return. The correct method is to subtract the exchange-reported gains on Form 8949 and replace them with the accurate figures from your crypto tax software. This is called an adjustment. It tells the IRS you considered the 1099-DA and chose to correct it under the proper reporting standard.

Q: My tax preparer says they won't handle crypto returns this year. Why?

A: The 1099-DA does not provide the summary totals that preparers expect from a 1099-B. Preparers handling stock returns can work from clean totals. The 1099-DA requires manual calculation to figure out how the numbers were derived, which is not commercially practical for many standard-fee returns.

Q: Is the IRS actually able to audit crypto returns effectively right now?

A: Revenue agents face the same reconciliation challenges as taxpayers. A 1099-DA does not map directly to a completed tax return, and agents who cannot work through cost basis mismatches may issue incorrect findings or abandon the review. The current system creates real uncertainty in how audits are handled.

Q: I got a CP2000 notice saying I underreported. The IRS is using my 1099-DA numbers. What do I do?

A: A CP2000 is a proposal, not a final assessment. You can respond with a written explanation showing that the 1099-DA figures do not reflect the correct cost basis under IRC Section 1012, and that your crypto tax software output is accurate. Attach supporting documentation. For larger amounts, working with a crypto tax professional is advisable.

Q: I need help sorting out a 1099-DA discrepancy or an IRS audit involving crypto. Where do I start?
