The Internal Revenue Service (IRS) is the U.S. federal agency responsible for collecting taxes and enforcing the Internal Revenue Code, and it treats virtually every cryptocurrency transaction as a taxable event subject to property tax rules. For anyone holding, trading, or earning digital assets in the United States, the agency's guidance, forms, and enforcement posture define what gets reported, what gets taxed, and where the legal risk lies.
How the IRS Classifies Cryptocurrency
The foundational position dates to 2014, when the agency issued Notice 2014-21, declaring that virtual currency is treated as property for federal income tax purposes rather than as currency. That single classification drives almost everything that follows. Because crypto is property, general tax principles for property transactions apply: when you sell, trade, or otherwise dispose of a digital asset, you recognize a capital gain or loss measured against your cost basis (what you paid, adjusted for fees).
Holding period matters. Assets held one year or less generate short-term capital gains, taxed at ordinary income rates; assets held longer than a year qualify for long-term capital gains, with preferential rates that can be as low as 0% depending on income (IRS digital assets guidance). Crucially, taxable events are broader than many investors assume. Selling crypto for dollars is taxable, but so is trading one token for another, spending crypto on goods or services, and receiving crypto as income from mining, staking, airdrops, or forks. The persistent belief that crypto-to-crypto swaps are tax-free is one of the most common and costly misconceptions, and it underlies recurring warnings about forked coins and "non-taxable" amendment claims that can trigger unexpected gain recognition.
Every Form 1040 now opens with a digital asset question asking whether the filer received, sold, exchanged, or otherwise disposed of a digital asset during the year. Answering it falsely is a separate exposure from any underlying tax owed.
Half of US crypto owners skip IRS reporting as study of 17M taxpayers exposes massive compliance gap
A study by Hoopes, Menzer, and Wilde analyzing IRS data from 2013–2021 found that while 12–21% of US adults own crypto, only about 6.5% of taxpayers actually report transactions — meaning roughly half of all crypto holders are dodging their tax obligations. Those who do report tend to be younger, lower-income, and less financially sophisticated, suggesting the bigger players are the ones slipping through. The findings land right as new Form 1099-DA rules kick in for the 2025 tax year, requiring exchanges to report gross proceeds directly to the IRS for the first time.
Readers click IRS-crypto stories most heavily when personal criminal liability is the frame — the $10k felony headline outperformed every policy or enforcement angle by a wide margin, revealing that the underlying fear is not tax complexity but prosecution risk for ordinary holders who assumed crypto was a gray area.
Cost Basis and the Wallet-by-Wallet Rule
Calculating gains requires knowing cost basis, and this is where compliance becomes genuinely difficult. Investors who move assets across multiple wallets and exchanges over many years often cannot reconstruct what they originally paid—producing the dreaded "unknown" basis that defaults to a cost of zero and inflates the taxable gain.
The IRS sharpened this area with Revenue Procedure 2024-28, which requires taxpayers to track basis per wallet or account rather than under a universal, pooled method. Effective January 1, 2025, each acquisition and disposal must be traced within its original account. The procedure offered a one-time safe harbor allowing taxpayers to allocate unused basis across their wallets as of that date, and it recognizes two inventory methods: specific identification and first-in, first-out (FIFO). The practical takeaway is that careless record-keeping is no longer salvageable after the fact—taxpayers must maintain contemporaneous, account-level records or risk losing the ability to substantiate basis at all.
Form 1099-DA: The New Reporting Regime
The most consequential recent change is Form 1099-DA, Digital Asset Proceeds From Broker Transactions. Under final regulations, custodial brokers—centralized exchanges such as Coinbase and Kraken, hosted-wallet providers, payment processors, and crypto kiosks—must report customer sales to the IRS, mirroring how stock brokers issue Form 1099-B (IRS final broker regulations).
The rollout is phased:
- 2025 transactions (reported in early 2026): brokers report gross proceeds only. Cost basis is not required, and the IRS granted transitional penalty relief for good-faith filing errors.
- 2026 transactions (reported in 2027): brokers must also report cost basis.
This gap creates a predictable problem. For the 2025 tax year, exchanges tell the IRS how much customers sold but not what they paid, leaving traders to reconstruct purchase prices themselves. Mismatches between a 1099-DA's reported proceeds and a taxpayer's own gain calculation are a likely audit flag. Recipient copies of the 2025 form are due by February 17, 2026, with IRS filing deadlines following at the end of February (paper) or March 31, 2026 (electronic) (Form 1099-DA instructions).
For investors, the structural shift is simple: the era of self-reported, hard-to-verify crypto income is ending for activity on centralized platforms. The agency will increasingly receive third-party data it can match against returns.
HYTOPIA pauses infrastructure and websites for 1-3 months after IRS tax refund delay stalls funding
HYTOPIA — the voxel gaming platform built by the ex-NFT Worlds team — is pausing all infrastructure and websites for an estimated 1-3 months, blaming a delayed IRS tax refund for leaving them in a funding crunch. The project raised $8M in a node sale and positioned itself as Minecraft-with-blockchain after Mojang banned NFTs in 2022. Yet another web3 gaming casualty, though the trigger here is less tokenomics collapse and more "IRS is running months behind in 2026."
- 01DeFi broker KYC mandate
The IRS attempt to force DeFi front-ends into KYC and 1099 reporting — and the industry fight to kill it — generated clicks across every stage: proposal, lawsuit, Senate repeal, and Trump signature.
- 02Felony exposure for ordinary holders
The $10k-within-15-days criminal reporting rule was the single most-clicked headline, driven by fear that routine crypto activity could constitute a federal felony.
- 03Congressional repeal of IRS crypto rules
The Senate CRA vote and Trump's willingness to sign drew repeated reader attention as the first successful legislative rollback of an IRS crypto regulation.
- 04IRS surveillance and enforcement escalation
The 758% spike in IRS letters, John Doe summonses against Kraken, and the shift to near-real-time blockchain monitoring signaled readers that the opt-in compliance era was ending.
- 051099-DA reporting confusion
Exchanges reporting sale proceeds without cost-basis data left traders facing reconstruction of gains and losses, creating practical anxiety about filing correctly under a new regime.
- 06Massive compliance gap exposure
Data showing half of US crypto holders skip IRS reporting framed the stakes: either the IRS closes the gap through enforcement, or it concedes a structural non-compliance problem.
DeFi, Decentralization, and the Repealed Broker Rule
The reporting net does not extend everywhere. A companion rule would have imposed 1099-DA-style obligations on decentralized finance (DeFi) front-end providers—interfaces that facilitate on-chain swaps without custodying assets. Industry argued the rule was unworkable because non-custodial protocols cannot collect customer identity (KYC) data the way exchanges do.
Congress agreed. Using the Congressional Review Act, lawmakers passed H.J.Res.25, and President Trump signed it into law on April 10, 2025, nullifying the DeFi broker regulation (Ways and Means Committee; RSM analysis). The repeal means DeFi platforms operating purely on blockchain infrastructure are not required to file 1099-DA forms or collect KYC information. Centralized, custodial exchanges remain fully subject to reporting.
A vital caveat: repealing the reporting rule did not make DeFi activity tax-free. Income and gains earned through decentralized protocols remain fully taxable. The change shifts the burden of reporting back onto individual users, and the absence of a third-party form is not the absence of a tax obligation.
Enforcement: Summonses, Data, and the Compliance Gap
The IRS has steadily expanded its visibility into crypto. Its most powerful tool is the John Doe summons, used to obtain records on unidentified taxpayers. The agency first deployed one against Coinbase in 2016, ultimately compelling data on more than 14,000 customers.
That authority was tested in Harper v. IRS. James Harper, a Coinbase user, argued he held a reasonable expectation of privacy in his exchange records under the Fourth Amendment. Lower courts rejected the claim under the long-standing third-party doctrine—the principle that information voluntarily shared with a service provider loses constitutional privacy protection. In late June 2025, the Supreme Court declined to hear the case, leaving those rulings intact and affirming the IRS's broad power to obtain records from custodial exchanges without a warrant (CoinDesk; ABA Banking Journal). Coinbase had supported Harper's petition, warning that unfettered access risks "real-time" surveillance of on-chain activity.
Despite expanding data access, a substantial compliance gap persists. Newsroom reporting and industry studies suggest roughly half of U.S. crypto owners do not fully report their activity, and surveys from Coinbase and its tax partners indicate two-thirds of investors are unaware of basic IRS rules—potentially overpaying or underpaying by thousands. The combination of new 1099-DA data flows and widespread noncompliance sets up a collision: as the agency receives more third-party information, the penalties for unreported activity (accuracy-related penalties, interest, and in egregious cases fraud charges) become far easier to assess. At the same time, reported staffing cuts at the agency introduce uncertainty about enforcement capacity heading into the 2026 filing season, even as the data infrastructure tightens.
IRS flags AI-driven crypto scams as 2025 cyber theft losses hit $20B with over half stolen in crypto
IRS Criminal Investigation agent Harry Chavis says AI is supercharging crypto fraud schemes, with the FBI clocking $20B in 2025 cyber theft losses and over half stolen in crypto. The playbook is textbook pig butchering — WhatsApp cold DMs, fake customer service, emotional manipulation — now juiced with AI to scale the grift. One 73-year-old victim lost $300K over three months in a scheme that off-ramped more than $5M total through exchanges.

Legislative Pressure and Open Questions
Crypto's tax treatment remains politically contested. A recurring proposal is a de minimis exemption—a threshold below which small personal crypto transactions (buying coffee, paying for a service) would escape capital gains reporting, addressing the absurdity of tracking gains on a few dollars of spending. Legislative vehicles such as the proposed PARITY Act would direct the IRS to study or implement such breaks, and think tanks like Cato have argued more aggressively for scrapping crypto capital gains taxation altogether, citing enforcement costs and market distortion. None of these has become law, and investors should treat current rules—not pending bills—as binding.
Other unsettled areas include the taxation of staking rewards (when income is recognized), the treatment of forked and airdropped coins, and whether losses from scams or fraud are deductible. The last point is being actively litigated; one widely covered case features a scam victim suing to deduct roughly \$800,000 in losses, reflecting genuine ambiguity after the Tax Cuts and Jobs Act narrowed personal casualty and theft loss deductions.
A New Frontier: AI Agents and Crypto
An emerging wrinkle sits at the intersection of artificial intelligence, crypto, and tax administration. Autonomous AI agents are beginning to interact directly with financial and government systems—one notably formed a U.S. corporation, obtained an IRS Employer Identification Number (EIN), and opened a bank account and crypto wallet to trade independently. The IRS has separately flagged AI-driven crypto scams as a growing enforcement concern amid record cyber-theft losses. These developments raise novel questions about who bears tax-reporting responsibility when software entities transact on-chain, and the existing framework offers no clear answers yet.
- RegulatoryHigh
The IRS has cycled through proposed rules, a finalized DeFi broker mandate, legislative repeal, and renewed enforcement letters — the regulatory surface remains unstable and the felony-level $10k reporting requirement adds criminal exposure to ordinary holders.
- CentralizationHigh
Centralized exchanges are the primary IRS data chokepoint: John Doe summonses against Kraken, Supreme Court refusal to block Coinbase data access, and the 1099-DA mandate all treat CEXs as the enforcement lever, making exchange-held assets far more surveilled than self-custodied ones.
- MarketMedium
Compliance uncertainty — including ambiguous cost-basis reporting under 1099-DA and contested staking income treatment — creates pricing and valuation risk for tokens heavily traded or staked by US retail holders.
- Smart-contractMedium
The finalized DeFi broker rule (subsequently repealed) and its threatened 2027 KYC mandate for front-ends established a precedent that smart-contract interfaces, not just custodians, can be regulated as brokers, leaving protocol teams with ongoing legal exposure.
Outlook
The trajectory is clear even where specifics remain unsettled: the IRS is moving crypto from a self-reported honor system toward a third-party-data regime that closely resembles traditional securities reporting. Form 1099-DA, wallet-level basis tracking, and affirmed summons authority all point the same direction—more visibility, less room for inadvertent or willful underreporting. DeFi retains a lighter reporting footprint after the 2025 repeal, but that is a reporting reprieve, not a tax exemption. For investors, the durable advice is to keep meticulous, account-level records, reconcile against the forms exchanges now issue, and treat every disposal as potentially taxable. Legislative relief like a de minimis threshold may eventually simplify everyday use, but until enacted, the safest assumption is that the agency can see more than ever and expects accurate reporting to match.
