Are you facing a crypto tax audit? If an IRS audit notice just landed in your mailbox, you are probably anxious about the scrutiny ahead and unsure what happens next. How does a crypto tax audit work, and how do you prove you filed correctly and paid the right tax? Below, our crypto tax attorneys explain how IRS audit representation works and break down everything you need to know about IRS digital asset audits, including the crypto tax audit defense strategies that help you negotiate the best possible outcome.
What Is a Crypto Tax Audit?
An IRS crypto tax audit is how the IRS verifies that you have accurately reported—and paid—taxes due on your crypto and digital transactions. The purpose of crypto audits is to prevent taxpayer noncompliance, identify tax fraud, and promote responsible digital trading.
- IRS crypto tax audits are limited to crypto matters. But evidence of tax fraud could lead to further investigations and scrutiny.
- Taxpayers face interest, financial penalties, and even criminal prosecution for irregularities and inconsistencies—especially if high volume trading is involved.
In many ways, crypto audits are similar to regular tax audits. But given how new and complex crypto tax rules can be, it’s crucial to understand how the process works and what differences you may encounter.
How Does the IRS Know I Traded Crypto?
The IRS uses several tools to track crypto activity. It monitors public blockchains, and major exchanges such as Coinbase are legally required to report customer transactions. Beginning with the 2025 tax year, U.S. exchanges must also issue Form 1099-DA, a dedicated digital asset broker report the IRS receives directly. The agency has also used John Doe summonses to pull user records from exchanges including Coinbase, Kraken, and Poloniex. These summonses can even extend your statute of limitations for audit for several years! If the income on your return does not match the data the IRS already holds, that mismatch can trigger a crypto tax audit.
The takeaway? Every blockchain transaction is traceable. Whether you trade crypto as a business or an individual, the IRS can follow your trading activity––and spot mismatches in reported and actual income.
Why Was I Selected for a Crypto Tax Audit?
While IRS crypto audits can be entirely random, there are some anomalies that make the IRS more likely to flag trading activities for further investigation.
- Exchange Reporting Mismatches: Any discrepancies, such as missing trades, or a mismatch between your gross income and reported earnings can invite IRS scrutiny.
- Failure to Report Income: Failing to report any income from crypto, surprising spikes in income, or failing to report what you originally sold tokens for can trigger audits.
- Income Miscalculations: If you miscalculate your capital gains, ordinary income, or any other income related to digital trading and crypto, it’s a potential red flag for the IRS.
- Prior Non-Compliance: Traders with a prior history of non-willful or willful non-compliance are more likely to face IRS audits than those with no prior history of tax return issues.
- Large Sum Movement: In some cases, moving large sums, or cashing out large sums which are atypical for the trader, can be enough to trigger an IRS audit.
The IRS can easily cross-reference data from centralized exchanges and information provided on tax returns to spot anomalies. Even a single oversight can raise questions or even lead to a full IRS investigation.
What Does a Crypto Tax Audit Include?
It depends on the scope of the individual audit, but typically, audits cover tax returns for the last three years. And if the IRS has reason to believe there is a significant or long-standing history of unreported income, it can review as far back as six years’ worth of tax returns.
What about if the IRS suspects actual tax fraud? In these cases, there’s no limit to how far back the IRS can go. They can review an unlimited number of tax returns to complete their investigations.
Are There Different Types of Tax Audits for Crypto?
The IRS can perform a tax audit in one of three ways: at your home or office, by correspondence, or at an IRS office.
- Field Audits: This is the most invasive type of audit. The IRS sends agents to visit your home or business and conduct intensive investigations. Typically, such audits are reserved for suspected high-value tax fraud or large-scale crypto mining.
- Correspondence Audits: The most common type of audit, the IRS sends notice of inconsistencies they wish to investigate and taxpayers must send specific documentation to the IRS for them to inspect. Unless there are disagreements regarding tax owed, or the IRS has concerns regarding larger-scale tax evasion, they are usually the least invasive, too.
- Office Audits: Taxpayers are required to visit a local IRS office to meet with agents and go over their cryptocurrency activities. Office audits are usually reserved for concerns regarding high volume, unexplained crypto trading, suspected tax evasion, or business-related crypto trading.
Regardless of the type of crypto audit proposed by the IRS, they’re equally serious and can lead to significant penalties or high amounts of tax owed. The Gordon Law team can help you understand the IRS tax audit procedure you’re facing, how it works, and what you might expect along the way.
What Information Will I Need for a Cryptocurrency IRS Tax Audit?
You’ll need any data you have to support your cost basis, transaction history, and proposed income. Examples of information you will need include:
- Wallet IDs
- Blockchain addresses
- Accounting method(s) used to support capital gains and taxable events
- Fair market value at time of acquisition and disposal of each token
- Date and time of acquiring and disposing of each token
- Documents you have issued by exchanges e.g. Form 1099s
- Details of tracking and/or accounting software used
The information you need varies depending upon the scope of the audit, but the simple principle is that the more data you have on hand to support your tax declaration, the better.
Can I Ignore an IRS Crypto Audit?
It’s unwise to ignore IRS notices, including warnings of a tax audit. Perceived acts of non-compliance can lead to serious penalties, including fines, enforced tax collection, and even prosecution in some cases.
The best thing you can do upon receiving notice of an impending IRS audit is to seek legal advice so you can identify the best crypto tax audit defense strategies for your unique situation.
Can I Avoid an IRS Crypto Audit?
There’s no way to completely eliminate the risk of an IRS crypto audit. But here are some tips for reducing the likelihood of attracting IRS attention:
- Use specialized crypto tax software or programs to accurately track every transaction or taxable event.
- File your returns on time and ensure they are accurate to avoid compliance issues which could, in the future, make you more likely to draw IRS scrutiny.
- Maintain detailed records e.g. purchase records, wallet transfers, bank statements, and transaction histories. The more data you have to support your declared taxable income, the less risk of an IRS audit.
- Seek legal advice on tax planning and crypto tax mitigation. Gordon Law can help you fully comply with your IRS obligations while seeking ways to mitigate tax owed.
The key points are to always have a defendable cost basis and to maintain an accurate paper trail. Even if you do face an IRS crypto audit, you will be in a far stronger negotiating position if you have data to support your proposed tax owed.
How Long Do Federal Cryptocurrency Audits Take?
It depends on the complexity of your situation. For example, if you agree with the outcome of an audit and you have a relatively simple portfolio, an audit will take less time than if e.g. you appeal the outcome of an IRS tax audit to the tax court or beyond. Simple cryptocurrency audits may only take a few months, but the most complex audits can take well over a year to conclude.
If you’re facing an IRS audit for crypto, your Gordon Law attorney can explain what to expect and how the timeline might unfold for you.
Do All Crypto Tax Audits Follow the Same Procedure?
For the most part, yes. IRS tax audits are governed by federal rules, the Internal Revenue Code, and the Internal Revenue Manual. This means that they should follow a predictable path, helping taxpayers understand what to expect and ensuring consistency across IRS audits.
- Once you know how crypto tax audits work, you can take steps in advance to reduce your risk of triggering an audit in the first place.
- Knowing how crypto tax audits unfold helps you take advantage of any possible defense strategies that may be open to you––and allows you to execute them at the most effective stage in any audit.
Your Gordon Law cryptocurrency attorney will explain how audits for cryptocurrency and other digital assets work in more detail as they relate to your specific case.
What Is the IRS Crypto Tax Audit Procedure?
Since IRS crypto tax audits follow a set trajectory, we can clearly break down each step so you have a better idea of what to expect if you receive notice of a pending IRS audit.
1. Opening Notice
Every audit begins with an IRS notice. This notice informs the taxpayer of the pending audit and confirms whether it’s a field, office, or mail audit. It also sets out:
- The name of the IRS examiner
- Issues under investigation
- Tax years under examination
The form you will receive depends on the type of audit and whether it’s a personal or business audit. For example, a business may receive Letter 2205-B, whereas an individual may receive a notice such as a CP2000 Notice. And you may receive a form such as IRS Form 6173 if the IRS believes you have underreported income from crypto—this is a more serious notice to receive and requires a prompt response.
Take the time to read the notice thoroughly and ensure you understand it. Your Gordon Law attorney can help with any issues you may have.
2. Initial Interview
Next, it’s the initial interview. The point of this interview is to explore your crypto and digital asset trading history. The examiner needs to know, for example:
- What exchanges you used
- The type of transactions and trading activities you undertook
- Whether you used foreign or offshore platforms
The answers you provide during this interview will determine the scale of the crypto audit. It is crucial to get legal advice before this interview, whether in person or remote, because you risk volunteering “too much” information and accidentally widening the scope of the investigation. A matter that could be resolved quickly may instead spiral into a lengthy audit.
3. Information Documentation Request (IDR)
The IDR, or Form 4564, is a roadmap for the entire audit. Form 4564 lists critical information, including the specific information the examiner requires, the documentation you must provide, and your deadline for responding––the maximum is usually 30 days.
What type of data might the examiner request? It varies, but new crypto audit rules mean that the IRS will seek full disclosure of everything from your digital wallets to crypto products used. So, common requests will include:
- Foreign exchange records
- Wallet addresses
- Documents supporting your cost basis
- Crypto exchange statements
Form 4564 is an evolving document, meaning that once you respond to one request, the examiner can issue another and so on until follow-up questions have been resolved. Each Form 4564 forms part of a paper trail which you can use to support any subsequent tax payment appeal, but they can also be used by the IRS to allege tax evasion or to justify penalties. Your Gordon Law attorney can help you respond succinctly to Form 4564 requests and will assist you in narrowing the scope of the investigation.
4. Examination Report
Now it’s time for the examiner to report on their findings. At this stage, the examiner issues a formal report to propose adjustments to tax owed. The report will:
- List each proposed change to the return;
- Calculate the tax and interest now owed; and
- Propose penalties due.
For example, you may face adjustments for unreported income, changes to your cost basis, or foreign reporting penalties if offshore crypto trading is involved.
You can respond to the report before it is finalized. This stage is critical––a careful, well-executed response supported by clear evidence can result in reduced adjustments or penalty waivers, which can mitigate tax owed and limit the long-term risk of related issues such as tax debt.
5. 30-Day Letter
Ideally, the taxpayer and auditor can agree on any adjustments to tax owed at the initial examination level. But if there are disagreements, then the IRS issues the taxpayer a 30-day letter. The letter enables taxpayers to petition to the IRS Independent Office of Appeals for a further review.
It’s common for crypto audits to reach the appeals stage, so don’t worry if you find yourself dealing with a 30-day letter. Your Gordon Law tax audit attorney will help you with what comes next.
6. IRS Appeals Process
The IRS appeals process is actually separate from the audit process. Meaning, it’s governed by its own unique rules and procedures. Most crucially, when considering a taxpayer’s appeal, officers are bound to consider the risks of losing any or all of its points in dispute against allowing the dispute to proceed to more formal litigation.
In other words, if there’s a substantial risk that the appeals court could find in the taxpayer’s favor, especially when we consider how new and relatively unpredictable crypto tax rules are, they’re more likely to settle the disputes out of court. This is good news for taxpayers—a well-drafted appeal petition could be the difference between settling or finding yourself at the tax court.
How do you improve your chances of making a successful petition? Here are some tips:
- Be clear and concise. Set out your position in a logical manner.
- Include the adjustments in dispute, why they’re unfair, and your proposals. Use legal authority where possible to support your position.
- Retain legal advice before sending your correspondence to the IRS. Your attorney will ensure your points are fully supported, clear and cohesive, and as compelling as possible.
You only have 30 days to submit your correspondence. This deadline is firm. The examiner’s proposals will stand if you fail to make counter-proposals in time.
7. Appeals Conference
The appeals conference is fairly informal and can take place in person or remotely.
- An appeals officer considers the taxpayer’s written submissions and any supplementary information provided.
- They will use their fairly wide settlement authority and the principle of avoiding litigation to, ideally, resolve matters at this stage.
- The officer issues a closing agreement, or Form 870-AD, to formalize closure of the dispute. If the matter can’t be resolved, they won’t issue this letter and the case proceeds to the next stage.
With your attorney’s help, it’s absolutely possible to resolve your tax dispute at this stage without the need for further action. But sometimes, there’s too much in dispute or the issues are serious enough to merit further action, which is where the tax court comes in.
8. Statutory Notice of Deficiency
A statutory notice of deficiency, or 90-day letter, triggers the U.S. Tax Court process.
- Taxpayers have 90 days from receipt of the notice to petition the U.S. Tax Court.
- For non-residents, this deadline is extended to 150 days.
There is absolutely no scope for extensions here, the deadlines are final. Should you miss the deadline, the examiner’s assessment stands and there’s no opportunity to reconsider unless you trigger an extensive and highly complex refund procedure after paying the tax.
Received a 90-day letter? If you don’t already have legal counsel, call us immediately. The longer you delay, the higher the risk of missing the deadline.
9. Tax Court Petitions
The purpose of petitioning the U.S. Tax Court is, of course, to challenge the proposed adjustments and tax owed. But what’s crucial to note is that once you petition the court, you don’t need to pay the tax until the matter is resolved.
Cases are heard by specialist federal judges. You’ll be assigned as a small tax case, with simplified procedures, if you allegedly owe $50,000 or less. Larger proposed adjustments have more complex rules which your attorney can advise you fully on.
There’s still plenty of scope to settle at this stage before a formal trial, and this is the most common outcome. But regardless of what procedure you’re under, tax court trials have common elements.
- The taxpayer and the IRS present evidence.
- Witnesses may be called, including blockchain experts and other specialists.
- Both parties can cross-examine and challenge evidence.
- The judge makes a determination based on the facts and evidence presented to the court.
Tax court hearings are highly complex and nuanced. Rather than attempting to navigate such a challenging process alone, trust the U.S. Tax Court attorneys at Gordon Law to represent you and present the most compelling possible case in your favor.
10. Tax Assessment and Collection
Once matters are resolved, whether it’s through the initial examination or a trial, the IRS confirms the tax due and triggers the collection process.
- If you can’t pay the liability in full, there are options for e.g. payment plans and offers in compromise.
- If you can’t pay anything e.g. you’re in severe financial hardship, it may be possible to declare Currently Not Collectible (CNC)
Unsure how to comply with IRS collections rules? Don’t panic—that’s what our tax attorneys are here to help with.
What Are the Most Common and Effective IRS Crypto Tax Audit Defense Strategies?
We must emphasize that the most effective crypto tax audit defense strategy is the one that is unique and tailored to your situation, which is why hiring a tax lawyer for support is so critical. But generally, successfully defending IRS crypto audits and mitigating tax owed comes down to the following strategies.
1. Retaining Experienced Counsel Immediately
Crypto audits, like any IRS audit, are highly nuanced and demand careful handling to avoid severe penalties. The moment you receive notice of an IRS crypto audit, call Gordon Law for experienced crypto tax audit representation. We will assess your position, identify the most effective defense strategies, and work to resolve the audit as quickly and favorably as possible.
2. Filing Form 2848
Filing Form 2848 as soon as possible after receiving notice of an IRS audit. The form tells the IRS that an attorney has Power of Attorney over the case. Your attorney can handle communications on your behalf which reduces the risk of oversights, and you will have attorney-client privilege over the entire audit defense strategy, which could prove invaluable depending on your tax situation.
3. Establishing a Solid Cost Basis
Your cost basis is the original price you paid for each token. And so proving your cost basis is critical to defending IRS audits and proposed adjustments.
If you can’t justify your cost bases across transactions, the IRS assumes the basis is zero. You will be taxed on the entire gross proceeds unless you can prove otherwise. So, you must clearly establish the bases you’re using and be able to justify your accounting methods.
- You can use, for example, blockchain data to prove acquisition dates.
- If there are insufficient records, it may be possible to rely on historical price data.
- Consider using crypto tax software to reliably record and store transaction histories.
Struggling to prove your cost basis for even a single transaction? The Gordon Law tax attorneys can help piece together a sufficient paper trail, and compelling counter-arguments, based on the evidence you have available.
4. Compiling Complete Transaction Logs
Reconstructing your transaction history is helpful in justifying your reported taxable income. You can do this by compiling the data you have available, including wallet activity, bank statements, and records of transaction dates and times.
If you have incomplete logs, you can often reconstruct your history e.g. through bank or credit card data, exchange data, and even email receipts. Our team will evaluate the evidence available to determine how best to defend your position.
In some cases, it may even be possible to argue reasonable cause e.g. you made decisions based in good faith and errors are non-willful. Again, this is when it’s best to turn to an attorney for advice—even a single misstep can convince the IRS that you indeed acted willfully, which can result in stricter enforcement action.
5. Considering Voluntary Disclosure or Amnesty Programs
Sometimes, the best defense against IRS audits is taking every possible step to avoid enhanced scrutiny in the first place. If you have failed to report crypto income, or suspect you haven’t complied fully with your tax return obligations, then consider either filing through the Voluntary Disclosure Program (VDP) for willful non-compliance, or the Streamlined Filing Procedures (Domestic or Offshore) for accidental non-compliance.
Unsure if an IRS amnesty program is suitable for your situation? The Gordon Law team can explain the options and help you decide if any program is feasible for moving forward.
