Every individual income tax return now asks you a direct question about digital assets. Most people answer it in two seconds. Some answer it wrong, either by mistake or because they hoped “No” would keep the IRS from looking.

If you are in the second group, or you are not sure which group you are in, this page explains why that checkbox matters so much more than its size suggests, and what to do about it.

What the question asks

The 2025 Form 1040 asks: “At any time during 2025, did you: (a) receive (as a reward, award, or payment for property or services); or (b) sell, exchange, or otherwise dispose of a digital asset (or a financial interest in a digital asset)?”

The 2025 Instructions for Form 1040 say not to leave it unanswered: “You must answer ‘Yes’ or ‘No’ by checking the appropriate box.” They also say you must answer it whether or not you received a Form 1099-DA.

When the answer is “Yes”

Under the 2025 instructions, you check “Yes” if during the year you received digital assets as payment for property or services, received them as a reward or award, received new digital assets from mining, staking or similar activities, received them from a hard fork, disposed of digital assets for property or services, traded one digital asset for another, or sold a digital asset.

The instructions also list actions that alone generally do not require “Yes”: holding digital assets in a wallet or account, transferring them between wallets or accounts you own or control, and purchasing digital assets with U.S. or other real currency.

If you bought Bitcoin with dollars and held it all year, “No” can be correct. If you swapped it for anything, sold any of it, or earned any staking rewards, it was “Yes.”

Why the IRS cares about this one box

The IRS fraud handbook lists, as an example of fraud relating to unreported income in digital asset cases, “intentionally answering ‘No’ to the question of digital asset use on tax returns despite the taxpayer’s knowledge” that they received digital assets as payment, as a reward, from mining or staking, from a hard fork or airdrop, or disposed of digital assets, traded them, or sold them. See IRM 25.1.2.11.1.

The handbook notes that evidence of those activities can come from an interview with the taxpayer or preparer, blockchain analysis, internal research, or review of financial records provided by the taxpayer or obtained by summons.

The reason is obvious once you see it. Unreported income can be an honest mistake. A false answer to a direct, plain-English question is harder to explain as one. The question converts “I didn’t know” into “I was asked and said no.”

The IRS has been telling people for years

IRM 25.1.2.11.2 is titled, bluntly, “IRS Has Repeatedly Informed Taxpayers of the Requirement to Report Digital Asset Transactions.” It lists the history: Notice 2014-21 in March 2014; IR-2018-71 in March 2018; the virtual currency campaign in July 2018; the letters in IR-2019-132 in July 2019; FAQs in December 2019; IR-2022-61 in March 2022, reminding taxpayers of the virtual currency question at the top of the 2021 Form 1040; and further reminders in 2023 and 2024.

It also notes that the digital asset question appears on Forms 1041, 1065, 1120 and 1120-S, not just individual returns. And it tells IRS personnel to consider these materials, along with other facts and circumstances, when evaluating whether a taxpayer can meet the reasonable cause exception to penalties.

In other words, the IRS has built a record that the question was clear and widely publicized. That record will be used.

How the answer shows up in an examination

In a crypto exam, the examiner will have your return, including the box you checked, and whatever third-party data the IRS holds, such as Forms 1099-DA for sales on or after January 1, 2025, or exchange records obtained by summons for earlier years. A “No” next to a stack of information returns is the first thing the examiner will ask about.

Expect the question in the initial interview or in an Information Document Request: why did you answer “No”? The honest answer, whatever it is, should come with documents. If a preparer checked the box, what did you tell the preparer? If you misunderstood, what did you think the question meant? See the crypto IDR guide.

Business owners should remember that the same question appears on partnership, corporation, S corporation and estate and trust returns, as IRM 25.1.2.11.2 notes. The analysis is the same. So is the importance of getting it right.

The perjury jurat

You sign your return under penalties of perjury. IRC 7206(1) makes it a felony to willfully make and subscribe a return verified by a written declaration under penalties of perjury that you do not believe to be true and correct as to every material matter, punishable by a fine of up to $100,000 for an individual, up to three years in prison, or both.

I am not telling you that a wrong checkbox will lead to prosecution. Willfulness is a high bar, and most wrong answers are mistakes. I am telling you that the question is part of a sworn document, and the government knows that.

Civil consequences

On the civil side, the wrong answer feeds into penalties rather than creating one by itself.

  • Accuracy-related penalty. If the wrong answer went along with unreported crypto income, the 20 percent penalty under IRC 6662 may apply to the resulting underpayment. A false “No” makes a reasonable cause defense under IRC 6664(c)(1) harder. See the crypto accuracy penalty.
  • Civil fraud penalty. If the IRS can prove fraud by clear and convincing evidence, IRC 6663 imposes a 75 percent penalty on the portion of the underpayment attributable to fraud. An intentional false “No” is one of the indicators the IRS looks for. See the civil fraud penalty.
  • Statute of limitations. A false or fraudulent return with intent to evade can be assessed at any time under IRC 6501(c)(1). See how far back the IRS can audit crypto.

If you answered wrong by mistake

Most wrong answers I see are honest. Someone thought staking rewards did not count until sold. Someone thought a crypto-to-crypto swap was not a sale. Someone’s preparer checked “No” without asking.

If that is you, fix it. File an amended return that reports the crypto activity correctly and answers the question correctly. Keep a short note in your file explaining what you misunderstood and when you learned otherwise. Correcting a mistake before the IRS asks is the clearest evidence that it was a mistake.

If the year also had unreported income, the amended return should include it. Do not fix the checkbox and leave the income off. That would make the record worse.

If the wrong answer was not a mistake

Then stop and talk to a lawyer before you file anything. How and whether to correct a return with a deliberately false answer is a legal decision with criminal dimensions, and the conversation should be privileged. Options exist, including the IRS Voluntary Disclosure Practice, but which one fits depends on facts that should not be posted in a blog comment or shared with anyone who cannot keep them confidential.

The worst move is to keep answering “No” in later years. Each year adds another signed statement to the pile.

And if you are reading this before you file this year’s return, the simplest fix of all is available: answer the question correctly this time, report what happened, and deal with the earlier years with advice.
