Timeline of IRS Digital Asset Enforcement

2014: The IRS Issues Its First Guidance on Digital Asset Taxation

The journey began in 2014 when the IRS released its initial guidance on virtual currencies. This document classified cryptocurrencies as “property” for tax purposes, making digital asset disposals subject to capital gains taxes. While this was a major step, it was only the beginning of the enforcement efforts we see today.

2018: The Formation of the Virtual Currency Compliance Campaign

The IRS created the Virtual Currency Compliance Campaign in 2018, signaling the start of a dedicated effort to address digital asset reporting non-compliance. This campaign was part of a broader effort to educate taxpayers about their obligations and initiate more targeted enforcement actions.

2019: Warning Letters to Digital Asset Holders

In 2019, the IRS began sending out thousands of letters (Letter 6173, 6174, and 6174-A) to digital asset holders who they suspected were underreporting or not reporting digital-asset-related income. These letters served as a warning and a reminder that the IRS was closely monitoring digital asset transactions.

2020: Digital Asset Question Added to Form 1040

One of the most notable shifts happened in 2020 when the IRS added a question regarding virtual currencies directly to Form 1040. This move ensured that every taxpayer in the U.S. would need to explicitly state whether they had engaged in digital asset transactions, making it much harder to ignore the reporting requirements.

2021: Operation Hidden Treasure

In 2021, the IRS launched “Operation Hidden Treasure,” a joint effort between the IRS Criminal Investigation unit and the Fraud Enforcement Office to root out taxpayers who were deliberately concealing digital asset income. This operation demonstrated the IRS's commitment to pursuing digital-asset-related tax fraud.

6. 2022: Hiring of Specialized Agents

In response to increasing digital asset adoption, the IRS hired hundreds of new agents in 2022 with specialized knowledge of blockchain technology and digital asset transactions. The bolstering of staff was a strategic move to better understand and track digital asset activities, ensuring more effective enforcement.

2023: The Coinbase Court Order

The IRS also took a significant step by securing a court order against Coinbase, one of the largest digital asset exchanges. This order required Coinbase to turn over user data to the IRS, providing details on transactions and customer identities. This landmark action was a wake-up call for digital asset investors, highlighting the growing reach of the IRS into the world of digital assets.

2023: Infrastructure Bill Reporting Requirements

The passage of the 2021 Infrastructure Bill, with new reporting requirements effective from 2023, made it mandatory for digital asset brokers to report transactions to the IRS, similar to the reporting requirements for traditional financial institutions. This marked a crucial legislative change to further ensure transparency and compliance in the digital asset industry.

2024: Operation Token Mirrors

In 2024, the IRS launched ‘Operation Token Mirrors,’ a targeted enforcement effort focusing on individuals and entities involved in pump and dump schemes. This operation showcases the IRS's ability to trace digital asset transactions more effectively and ensure compliance through enhanced scrutiny.

The IRS's approach to digital asset enforcement has evolved significantly over the past decade. From early guidelines to the hiring of specialized agents, court orders, and mandatory reporting requirements, the agency is leaving no stone unturned to ensure compliance.
