Eight US Lawmakers Challenge IRS Over Fork and Airdrop Tax Rules in Bipartisan Push

The Ruling

On December 20, 2019, eight members of the United States House of Representatives sent a pointed letter to IRS Commissioner Charles Rettig, demanding that the agency clarify its guidance on the tax treatment of cryptocurrency airdrops and blockchain network forks. The bipartisan group — led by Representatives Tom Emmer (R-MN), Bill Foster (D-IL), David Schweikert (R-AZ), Darren Soto (D-FL), Lance Gooden (R-TX), French Hill (R-AR), Matt Gaetz (R-FL), and Warren Davidson (R-OH) — expressed deep concern that recent IRS guidance had created more confusion than it resolved.

The letter directly challenged the agency’s approach to what constitutes “dominion and control” over forked or airdropped assets, warning that taxpayers could face “potentially unwarranted tax liability and administrative burdens.” The legislators pointed out that the guidance arrived almost two years after the Bitcoin and Bitcoin Cash fork and three years after the Ethereum fork — a delay they called “inequitable” to everyday crypto users who had been operating without clear rules.

Bitcoin traded at approximately $7,219 on the day of the letter, with Ethereum hovering around $129. The relatively subdued market conditions belied the significance of what was happening in Washington: for the first time, a sizable coalition of lawmakers was pushing back against the IRS on the specifics of crypto taxation, not just the principle of it.

International Precedents

The Congressional letter landed at a moment when global regulators were struggling with the same fundamental question: how do you tax something that appears in someone’s wallet without their explicit action? The European Union had been working on its own framework, with the European Banking Authority issuing warnings about anti-money laundering gaps in crypto-asset markets throughout 2019. In Japan, the Financial Services Agency had already tightened rules around exchange-traded cryptocurrencies following the Coincheck hack of early 2018.

The United Kingdom’s HM Revenue and Customs had published updated crypto tax guidance just weeks earlier, in December 2019, taking the position that airdrops received without doing anything in return may not be subject to income tax — a notably more relaxed stance than what the IRS was proposing. Meanwhile, Australia’s tax authority had issued rulings suggesting that forked tokens were only taxable once disposed of, not at the moment of the fork itself.

What made the American situation unique was the sheer complexity of its tax code and the retroactive nature of the IRS guidance. The agency had issued Revenue Ruling 2019-24 in October 2019, but its provisions effectively applied to events stretching back to 2017 — a period during which taxpayers had no official guidance to follow. This retroactive application was precisely what the eight representatives found most troubling.

Enforcement Reality

The letter asked the IRS three specific questions that revealed the depth of concern on Capitol Hill. First, would the IRS clarify its airdrop and fork hypotheticals to better match how these events actually occur in the cryptocurrency ecosystem? Second, would the agency define a clearer standard for “dominion and control” — one that requires “some level of knowledge and actual affirmative steps” rather than passive receipt? Third, and perhaps most critically, would any guidance be applied retroactively, or would the IRS issue proposed rules subject to public notice and comment?

Coin Center, the Washington-based crypto policy advocacy group, worked closely with Representative Emmer’s office on the letter. Neeral Agrawal, Coin Center’s director of communications, described getting cryptocurrency tax policy right as “a top priority” and praised Congress for “stepping in on this critical issue for its users.” The organization had been lobbying for clearer rules since the earliest days of the IRS’s involvement with crypto taxation.

The enforcement implications were enormous. If the IRS maintained its position that any fork or airdrop created an immediate taxable event at fair market value, millions of cryptocurrency holders could theoretically face penalties for failing to report tokens they may not have even known they received. This was not a theoretical concern: the Bitcoin Cash fork of August 2017 alone created new assets for every Bitcoin holder at the time, and the IRS had provided no guidance on how to handle it until more than two years later.

Market Shockwaves

The regulatory uncertainty had a measurable chilling effect on cryptocurrency adoption in the United States. With Bitcoin trading around $7,219 and the total cryptocurrency market capitalization well below its 2017 highs, institutional adoption was already sluggish. The fear of unexpected tax liabilities added another layer of hesitation for both individual and institutional participants.

Particularly concerning was the letter’s mention of crypto-related products beyond simple transactions — specifically futures, crypto-tied retirement accounts, and interest-generating crypto deposits. The representatives were effectively telling the IRS that its guidance was not keeping pace with the rapidly evolving DeFi ecosystem. At a time when lending protocols and yield-generating platforms were beginning to gain traction, the lack of tax clarity around these instruments threatened to stifle innovation in the American crypto market.

The timing was also significant. The letter arrived just as the 2019 tax filing season was approaching, meaning millions of cryptocurrency users would need to make decisions about how to report their forked and airdropped tokens without clear guidance from the agency that would ultimately judge their compliance. Tax professionals across the country reported widespread confusion among clients, with many unsure whether to report forked tokens at all.

Closing Thoughts

The December 20 letter represented a watershed moment in the relationship between Congress and the cryptocurrency industry. For years, lawmakers had largely ignored the technical nuances of digital asset taxation, leaving the IRS to fill the regulatory vacuum with guidance that often felt disconnected from the reality of how blockchain networks function. That eight representatives — spanning the ideological spectrum from Matt Gaetz to Bill Foster — agreed on this issue signaled a maturation of crypto policy thinking on Capitol Hill.

The broader lesson was clear: regulating emerging technology through outdated frameworks creates more problems than it solves. The IRS had attempted to squeeze novel concepts like airdrops and forks into existing tax categories designed for stocks and bonds, and the result was guidance that confused more than it clarified. The legislators’ request for prospective, rather than retroactive, rulemaking reflected an understanding that you cannot penalize people for failing to follow rules that did not yet exist. As the cryptocurrency market continued to evolve, this tension between innovation and regulation would only intensify.
