The Internal Revenue Service has steadily expanded its crypto monitoring capabilities since 2017, moving from narrow probes for individual traders to sweep requests for user records at major exchanges and crypto companies.
Armed with “John Doe Summonses” and increasingly sophisticated blockchain analytics, the agency can now track crypto transactions in real time, according to legal experts and government declarations.
“Initially, the IRS targeted narrower groups of individuals based on specific transaction thresholds,” David Klasing told CPA, a dual-certified tax lawyer and specialized in crypto taxation. Decryption. “However, recent cases demonstrate a broader approach aimed at identifying non-compliance with taxes across multiple crypto exchanges.”
The major exchanges and platforms, including Coinbase, Kraken, Poloniex and Circle, were among those initially targeted before enforcement spread across the sector.
Coinbase faced first tests when it was issued by the IRS Summoned In 2016, it was repeated in 14,000 accounts, later returned to court.
Execution push generated $3.5 billion cryptocurrency According to the agency’s Criminal Investigation Division, 2021 accounted for 93% of total IRS asset attacks that year.
In 2021, the agency secured approval for similar John Doe targeting Kraken users who traded more than $20,000 between 2017 and 2020, Kraken users who targeted customers who traded the same amount between 2016 and 2020, and Poloniex, an Exchange previously owned by Circle.
By June 2023, the IRS had started and submitted 216 exams Almost 15,000 “soft letters” According to Klasing, the Secretary of Tax Management Treasury (TIGTA), reported in July 2024 to cryptographic users identified through Exchange data.
The lawyer explained that three specific legal thresholds must be met before the IRS approves John Doe’s summon. This demonstrates investigations of “persons of a ‘confirmable group or class’, establishes “reasonable basis for believing in violation of tax laws” and proves that “information is not readily available from other sources.”
However, these requirements provide limited protection for crypto users. The court only needs “minimal” justification, and “the statute does not require that each person in the verifiable group demonstrate to the IRS that they have violated the law,” Klasing added.
Expand the internet
Since Coinbase was summoned, Klasing said the IRS has “expanded” the electronic payment system initiative originally built for electronic transfers, and is currently targeting “cryptocurrencies.”
According to IRS agent Karen Cincotta’s, agents currently combine Exchange Data with Blockchain Analytics to create a comprehensive financial profile and use “digital currency exchange data along with other publicly available blockchain information” to examine tax compliance. Survey results In a Kraken investigation, Klasing said.
2024Tigta has achieved a potential non-compliance rate of 75% among taxpayers identified through digital asset exchanges and fed directly into the audit pipeline. Early 2024.
The large business and international divisions have John Doe summoned information in a digital asset compliance campaign, running outreach and open testing, Klasing said.
Nick Waytula, lawyer and tax secretary for the Crypto Tax Calculator, Decryption “The expansion of John Doe will “significantly raise the compliance bar for crypto companies,” while also creating the risk that “whether careless or careless, there is a high chance that a fine will likely lead to penalties.”
Waytula described the shift as “a turning point in crypto tax enforcement.” Here, “The crypto tax changed to an ‘opt-out’ model, with compliance increasing across the board, and taxpayers had to voluntarily report data to the IRS. ”
from now on 1099-DA Reporting SystemAccording to Klasing, it is requesting 2025 disposal of covered securities and reporting basic reports in 2026, with the aim of reducing discrepancies in historical reports that caused false IRS notifications in 2026.
However, Waytula said, “Each Exchange’s 1099-DA does not contain information from other exchanges, wallets, or on-chain protocols,” warning that “mismatches and confusion can increase if the bottom of costs cannot be properly simplified or captured.”
notification
The class said Decryption His company has processed multiple clients who received notifications and “90-day letters” from the IRS regarding “large misreports by a well-known crypto exchange,” particularly between 2017 and 2019, “several exchanges issued 1099-K with a collective that neither our office nor the IRS can be recalibrated.”
The Government Accountability Office (GAO) found it 1099-K Forms only provide unfounded assemblies and call them “unhelpful or confusing.” The 1099-DA needs to address these defects, Klasing said.
“In reality, there can be errors,” Klasing adds, noting that a John Doe summon dataset, the IRS AI model of case selection is “trained with current return data,” according to a Tigta audit.
Dmitri Alexeev, Aprio’s CPA and tax partner, said Decryption The platform emphasizes the need to improve its “AML/KYC process and data collection, analysis and reporting” as it “sees “the development appears to be in line with the trajectory of Postcoinbase’s enforcement, not sudden policy changes, but increased regulatory attention.”
Alexeev explained that the IRS approach “reflects its focus on surveillance of crypto platforms,” and that “emphasizes the importance of companies maintaining robust reporting, recordkeeping and internal control.”
Privacy advocates say the Supreme Court lost the ground in July I refused to listen James Harper’s claims that the IRS violated his fourth amendment rights by obtaining Coinbase trading data through John Doe summons.
April, Coinbase backing he Amicus briefs have added several states and privacy groups, Elon Musk’s x.
The filing asked the court to reconsider “third-party doctrine,” a 1970s rule that provided government access to data held by banks or service providers, saying that the doctrine should not extend to crypto exchanges.
In its overview, Coinbase compared IRS access amounts to a “financial ankle monitor,” which alerts the “real-time monitor” of blockchain activity and allows for “nearly complete monitoring” of user transactions.
The Trump administration has removed controversial things Defi Broker rules from the Biden era If we eliminate the reporting requirements that forced a decentralized platform to collect user data from traditional brokerage companies, from the July tax code, central exchanges are subject to a comprehensive reporting obligation.
A “heavy enforcement” approach “risks of alienating submissive users” overwhelmed by complexity, Waytula said, saying many crypto traders are “anti-government” and “branch-centered” and that overregulation is likely to create “significant friction” with high-value taxpayers.
Although there is no official report showing “systematically incorrect” targeting of crypto users due to inaccurate exchange records, Klasing noted that even if the tax amount is correct, a matching program can generate a notification if a third-party information return does not match the return.
