Yes, cryptocurrency is reported to the IRS. It reaches the agency from two directions: the exchanges you trade on send transaction data directly to the government, and you report your own activity on your federal tax return. The IRS treats digital assets as property, so sales, swaps, and most earning events can create a tax bill.1Internal Revenue Service. Digital Assets Since 2025, centralized platforms have been issuing Form 1099-DA, which puts your trading history in the IRS’s hands whether or not you file correctly.2Internal Revenue Service. Final Regulations and Related IRS Guidance for Reporting by Brokers on Sales and Exchanges of Digital Assets If you don’t report, the consequences run from a 20% accuracy penalty to a 75% civil fraud penalty to felony tax evasion charges.
What Exchanges Send to the IRS
The Infrastructure Investment and Jobs Act expanded the federal definition of “broker” to cover platforms that regularly facilitate digital asset transfers for customers.3Office of the Law Revision Counsel. 26 USC 6045 – Returns of Brokers That pulled centralized crypto exchanges into the same reporting framework stock brokerages have operated under for decades. Exchanges verify your identity, collect your taxpayer identification number, and file Form 1099-DA with the IRS while sending you a copy.
The rollout is phased. For transactions on or after January 1, 2025, exchanges report gross proceeds — the total amount you received from each sale or exchange. Starting with transactions on or after January 1, 2026, they also report your cost basis on covered assets.2Internal Revenue Service. Final Regulations and Related IRS Guidance for Reporting by Brokers on Sales and Exchanges of Digital Assets Once basis reporting is fully live, the agency can see not just that you sold crypto but whether the gain you reported matches what the exchange calculated.
Before the 1099-DA existed, some platforms issued Form 1099-K (built for payment processing) or Form 1099-B (built for securities), and neither fit crypto cleanly. The 1099-DA replaces those workarounds with a form designed for digital assets.
What About Decentralized Exchanges and Self-Custody Wallets
If you trade through a decentralized exchange or use a non-custodial wallet, no broker is currently required to file a 1099-DA for you. The final regulations exclude platforms that never take possession of the assets being traded.2Internal Revenue Service. Final Regulations and Related IRS Guidance for Reporting by Brokers on Sales and Exchanges of Digital Assets Treasury and the IRS have signaled they intend to issue separate rules for decentralized brokers, but those rules have not taken effect. The absence of a 1099-DA does not eliminate your obligation to report those transactions. It just means the IRS won’t have the exchange’s copy sitting next to your return during matching, at least for now.
What You Have to Report on Your Return
Every person filing a Form 1040, 1040-SR, 1040-NR, 1041, 1065, 1120, or 1120-S has to answer a yes-or-no question at the top of the return about digital assets.4Internal Revenue Service. Taxpayers Need to Report Crypto, Other Digital Asset Transactions on Their Tax Return The question asks whether you received, sold, exchanged, or otherwise disposed of any digital asset during the year.1Internal Revenue Service. Digital Assets You sign the return under penalty of perjury. Checking “No” when the truthful answer is “Yes” creates legal exposure beyond just an incorrect return.
Which Activities Count
More crypto activity is taxable than most people expect. Selling crypto for dollars is the obvious case — the difference between what you paid and what you received is a capital gain or loss. Swapping one cryptocurrency for another is equally taxable, even though no dollars change hands. The IRS treats the swap as a sale of the first asset at its fair market value.5Internal Revenue Service. Frequently Asked Questions on Digital Asset Transactions Using crypto to buy a coffee or a car is also a disposal, priced at the market value at the moment of purchase.1Internal Revenue Service. Digital Assets
Mining rewards, staking income, airdrops from hard forks, and crypto received as payment for work or services are all ordinary income at the moment you gain control of the funds. The taxable amount is the fair market value at that instant.6IRS.gov. Rev. Rul. 2019-24 That same value becomes your cost basis for any future sale.
Transfers between wallets you control are not taxable. Moving Bitcoin from an exchange to a hardware wallet you own creates no gain or loss because you haven’t disposed of anything.
The Forms That Carry the Numbers
Each sale, swap, or other disposal goes on Form 8949, with the acquisition date, disposal date, proceeds, and cost basis.7Internal Revenue Service. About Form 8949, Sales and Other Dispositions of Capital Assets The totals flow to Schedule D, where all your gains and losses net out.8Internal Revenue Service. Form 8949 – Sales and Other Dispositions of Capital Assets If your exchange reported everything on a 1099-DA with basis included and you have no adjustments, you can enter aggregate totals on Schedule D without listing each trade. Ordinary-income items like mining or staking rewards get reported separately as income at the values they had when you received them.
How the IRS Finds Unreported Crypto
The IRS has several tools that make crypto far less anonymous than holders sometimes assume.
The most direct is the John Doe summons, a court-authorized demand served on an exchange for names and transaction records of users meeting certain thresholds. Federal courts have approved these summonses against multiple platforms, requiring production of records for users who transacted $20,000 or more in cryptocurrency.9U.S. Department of Justice. Court Authorizes Service of John Doe Summons Seeking the Identities of U.S. Taxpayers Who Have Used Cryptocurrency The IRS then compares that data against filed returns to find people who traded and didn’t report.
Blockchain analytics is the other major tool. Public blockchains are transparent by design; every transaction is permanently visible. The IRS contracts with analytics firms that tie wallet addresses to real identities by tracing the flow of funds between known exchange accounts and unknown wallets. Routing crypto through multiple wallets doesn’t defeat the analysis; it adds steps. The agency also shares data with international tax authorities through cooperation agreements and joint enforcement initiatives.
Then there’s the 1099-DA itself. With standardized transaction data flowing directly from exchanges, the matching process works the same way it does for W-2 wages and 1099 interest income. If your reported numbers don’t match the exchange’s numbers, the IRS sends a notice. As basis reporting rolls in for 2026 transactions, the agency will be checking not only whether you reported a sale but whether the gain you reported is correct.
What Happens If You Don’t Report
The consequences scale with the scale and intent of the underreporting.
- Accuracy-related penalty. If the IRS finds you understated tax through negligence or a substantial understatement, the penalty is typically 20% of the underpayment.
- Civil fraud penalty. If the IRS concludes you intentionally understated tax, the penalty rises to 75% of the portion of the underpayment attributable to fraud.10Office of the Law Revision Counsel. 26 USC 6663 – Imposition of Fraud Penalty
- Criminal tax evasion. Willfully attempting to evade tax is a felony carrying a fine of up to $100,000 ($500,000 for corporations) and up to five years in prison.11Office of the Law Revision Counsel. 26 U.S. Code 7201 – Attempt to Evade or Defeat Tax
Interest accrues on any unpaid balance from the original due date, so the cost grows the longer the issue sits. Criminal prosecution is uncommon for typical reporting mistakes, but the IRS has publicly stated it is prioritizing crypto enforcement, and the John Doe summons cases show the agency is building the infrastructure to bring more cases. The line between “honest mistake” and “willful evasion” often turns on whether the IRS can show you knew about the obligation and ignored it. That’s easier to prove when you checked “No” on the digital asset question and had a 1099-DA sitting in your inbox.
Statute of Limitations
The IRS generally has three years to audit a return. If you underreport gross income by more than 25%, that stretches to six years. If you never file a return or file a fraudulent one, there is no time limit.12Internal Revenue Service. How Long Should I Keep Records? Old unreported crypto activity does not necessarily age out.
Coming Forward Before the IRS Finds You
If you have unreported crypto income from prior years and haven’t heard from the IRS, the Voluntary Disclosure Practice is a path to resolve it while seeking protection from criminal prosecution. The program is designed for taxpayers who willfully failed to comply.13IRS Criminal Investigation. IRS Criminal Investigation Voluntary Disclosure Practice
The disclosure has to be timely. That means the IRS has not already started examining your returns, received information about you from a third party such as a John Doe summons response, or opened a criminal investigation. You apply through a two-part electronic process using Form 14457, first requesting preclearance and then submitting full documentation within 45 days of receiving the preclearance letter. You have to cooperate with the examiner and pay all taxes, interest, and applicable penalties in full or set up an installment agreement.13IRS Criminal Investigation. IRS Criminal Investigation Voluntary Disclosure Practice Voluntary disclosure doesn’t erase every penalty, but it substantially reduces the risk of criminal prosecution. Once the IRS has your data from an exchange summons or a 1099-DA match, that window is closed.
