I have unreported crypto. What are my options?

Last reviewed July 30, 2026 · Reviewed by Andrew Gordon, JD, CPA

If you have unreported crypto, current law gives you two main correction paths: file amended returns for the affected years if your mistake was not willful, or enter the IRS Voluntary Disclosure Practice (Form 14457) if it was. Records come first; penalties and lookback periods depend on which path fits.

Why so many people are in this position

If you have crypto activity from past years that never made it onto a tax return, you are far from alone. For much of the industry’s history, tax guidance was thin and most exchanges sent customers little or no tax reporting — no year-end form, no gain-loss statement, nothing resembling what a stockbroker provides. Meanwhile, the law treats digital assets as property under Notice 2014-21, which means every sale, every crypto-to-crypto trade, and every purchase made with crypto is a taxable disposition. Many people simply did not know. The question is no longer buried, either: Form 1040 now asks every filer whether they received, sold, exchanged, or otherwise disposed of a digital asset during the year.

Having unreported crypto does not by itself mean you acted willfully. How you got here matters, and so does what you do next.

What the IRS already sees

It helps to be realistic about the information the IRS already holds. In the Coinbase John Doe summons litigation, a federal court in 2017 ordered the exchange to produce account holders’ taxpayer ID numbers, names, birth dates, addresses, transaction logs, and periodic account statements. As narrowed, the summons targeted 14,355 Coinbase accounts — those with at least $20,000 in any one transaction type (buying, selling, sending, or receiving) in any one year from 2013 through 2015. The First Circuit’s 2024 opinion in Harper v. Werfel recounts the litigation — and affirms the dismissal of an account holder’s challenge to the IRS’s acquisition of those records.

That data did not sit idle. In 2019 the IRS mailed more than 10,000 letters to crypto owners whose names were “obtained through various ongoing IRS compliance efforts,” advising them to review their filings and, when appropriate, amend and pay back taxes, interest, and penalties. Our guide to IRS crypto letters covers what each of those letters means and how to respond.

Now the pipeline is automatic. Under the final broker-reporting regulations, digital asset brokers report gross proceeds on Form 1099-DA for transactions beginning in calendar year 2025, with cost-basis reporting required of certain brokers for transactions on or after January 1, 2026. Those forms feed the same document-matching systems that generate CP2000 notices when a return does not match what a third party reported.

The current-law menu

Non-willful mistakes: amended returns

For taxpayers whose errors were not willful — they misunderstood the rules, missed transactions, or did not realize an event was taxable — the IRS expects corrections through amended returns for the affected years. You recalculate your gain or loss with complete records and file corrected returns on Form 1040-X, paying the additional tax with the filing where you can: interest accrues on any unpaid balance from each return’s original due date until it is paid, so correcting sooner stops the meter sooner.

Willful noncompliance: the Voluntary Disclosure Practice

For taxpayers whose noncompliance was willful, the IRS operates its general Voluntary Disclosure Practice. It is initiated with Form 14457, which now includes a digital-assets section, and it runs in two parts: a preclearance request to confirm eligibility, then a full application. Two features matter most. A disclosure is timely only if the IRS receives it before opening an examination or investigation and before it obtains your information from a third party or an enforcement action. And it does not automatically guarantee immunity — the IRS says a complete, cooperative disclosure “may result in prosecution not being recommended.” The practice is not tailored to digital assets, and the willful/non-willful line is consequential, which is one reason many people in this situation work with a qualified tax professional.

Either way: get your records first

Both paths run on documentation. Before anything else, export transaction histories from every exchange and wallet you have used, and reconstruct what you paid and when — platforms shut down and data disappears. Our Form 1099-DA guide walks through the records worth gathering and why your own basis documentation matters more than ever.

Choosing a path — and what not to do

You may also hear about a third, unofficial route: the “quiet disclosure,” meaning a taxpayer with willful facts simply files amended returns and hopes no one looks closely. It is not a program, and it fits nothing. For genuinely non-willful errors, amending quietly is not a loophole — it is exactly what the IRS asks you to do. But for willful conduct, amending without a voluntary disclosure leaves the criminal exposure unaddressed while the window for a timely disclosure keeps closing as broker data arrives.

A few things not to do, whichever path fits:

• Do not start reporting correctly going forward while ignoring significant past years — the digital-asset question sits on a return signed under penalties of perjury, and the old years do not close themselves.
• Do not guess at cost basis. Reconstruct it from records; estimates you cannot support tend to collapse under examination.
• Do not discard or fail to preserve exchange data, wallet exports, or old emails — they are usually your best evidence, including evidence in your favor.
• Do not wait for a letter. Timeliness rules mean the options narrow once the IRS already has your information.
• Do not label yourself willful or non-willful casually. If the answer is not obvious, that judgment is worth professional advice before you file anything.

How far back can the IRS look?

Assessment limits come from Section 6501. The general rule is three years from the date a return is filed. The window doubles to six years when a return omits more than 25 percent of the gross income stated on it — and an understatement caused by overstated basis counts as an omission, which matters for crypto, where basis is often the weakest record. There is no limit at all for a false or fraudulent return, or where no return was filed: an unfiled year simply stays open.

The penalty framework

Corrections usually involve money beyond the tax itself, and it helps to know the pieces. The accuracy-related penalty under Section 6662 is 20 percent of the underpayment attributable to negligence or a substantial understatement — for individuals, an understatement exceeding the greater of 10 percent of the tax required to be shown or $5,000. It does not apply where the taxpayer shows reasonable cause and good faith. The civil fraud penalty under Section 6663 is far heavier: 75 percent of the portion of the underpayment attributable to fraud. For unfiled returns, Section 6651 adds a failure-to-file penalty of 5 percent of the unpaid tax per month up to 25 percent, alongside a failure-to-pay penalty of 0.5 percent per month, also capped at 25 percent. Interest is not a penalty and is rarely waived: it accrues from each return’s due date until payment, at a rate set quarterly — the federal short-term rate plus 3 percentage points for individuals.

One clarification, because it surprises people in both directions: holding crypto on a foreign exchange does not currently create an FBAR filing obligation by itself. Under FinCEN Notice 2020-2, a foreign account holding only virtual currency is not a reportable account — though an account that also holds other reportable assets can be, and FinCEN has said it intends to propose changing the rule, so this is a point to re-check rather than rely on.

If you cannot pay in full

An inability to pay everything at once is not a reason to leave old years uncorrected. The IRS offers short-term and long-term payment plans, and individuals can often apply online. Penalties are not always the last word either: the IRS abates penalties for reasonable cause, and its first-time abatement policy can remove failure-to-file and failure-to-pay penalties in some cases. When a penalty is removed, the interest charged on that penalty is reduced or removed with it. The interest on the tax itself, though, keeps running until the balance is paid.

A worked example

Suppose — purely as an illustration — that you swapped one coin for another in 2023, never reported the trade, and the omitted long-term gain works out to an additional $6,000 of tax on a return that was required to show $30,000. The understatement exceeds both $5,000 and 10 percent of the required tax ($3,000), so it is “substantial,” and if the 20 percent accuracy-related penalty applies it adds $1,200. Interest runs on the $6,000 from the return’s April 2024 due date until it is paid — which is the practical argument for correcting now rather than later, since the one component you can always shrink is how long the balance sits. Where your gains actually land depends on rates and brackets; our crypto tax rates guide covers the current numbers.

Step by step: how a correction actually proceeds

1. Export complete transaction histories from every exchange and wallet you have ever used, including closed accounts, before anything else disappears.
2. Reconstruct cost basis and recompute gain or loss for each affected year, on the same forms a correct original return would have used (Form 8949 and Schedule D for capital transactions).
3. Assess the willfulness question honestly — with professional advice if the answer is not obvious — because it determines the path.
4. File: Form 1040-X for each affected year for non-willful corrections, or Form 14457 preclearance if the Voluntary Disclosure Practice fits.
5. Pay what you can with the filing, or arrange payment — interest stops only when the balance does.
6. Keep copies of everything you file and every record behind it.

Why waiting tends to get harder

Broker reporting is maturing. Digital asset brokers report gross proceeds to the IRS on Form 1099-DA for transactions beginning in 2025, and they begin reporting cost basis for transactions beginning in 2026. As that third-party data accumulates, mismatches between what brokers report and what appears on a return become easier for IRS systems to identify.

Common questions

The policy question

There is no disclosure program tailored to digital assets, no standardized penalty framework for crypto disclosures, and considerable uncertainty about outcomes. Whether the IRS should create a program tailored to digital assets is a live policy question; our affiliate has taken a position, described on its section of this website.
