The Ruling
On August 13, 2018, a Fortune investigation revealed that dozens of cryptocurrency hedge funds managing billions of dollars in digital assets faced mounting uncertainty over whether they were calculating their taxes correctly — a problem that was about to become far more acute after the Internal Revenue Service announced it would make virtual currencies a focus of audits for its large business and international division.
The IRS had added cryptocurrencies to its list of “compliance campaigns” just weeks earlier, in July 2018, putting hedge funds on notice that their crypto holdings would come under heightened scrutiny. The agency told taxpayers with unreported transactions to amend their returns but notably declined to offer a voluntary disclosure program that would limit criminal and civil liabilities.
Bitcoin, which had plunged 55 percent since the start of 2018, still commanded a market capitalization of approximately $111.5 billion. Morgan Stanley estimated that investment firms had launched 84 cryptocurrency hedge funds in 2017 alone, collectively holding around $2 billion worth of virtual currencies. These funds now found themselves navigating a regulatory maze with almost no clear guidance.
International Precedents
The regulatory ambiguity was not confined to the United States. Around the world, jurisdictions were struggling to classify cryptocurrencies for tax purposes, and the inconsistencies between them created additional headaches for funds operating across borders.
The IRS had declared in 2014 that virtual currencies would generally be treated as property for tax purposes, meaning investors who traded Bitcoin needed to report gains and losses the same way they would for any other property. Cryptocurrency miners and others who received payment in digital currencies were also subject to the same reporting requirements.
However, the Commodity Futures Trading Commission took a different stance, classifying many virtual currencies as commodities. Several federal judges had reinforced that view over the preceding two years. If the IRS were to adopt the CFTC’s commodity classification, it could open up significant tax advantages for crypto funds — but no such alignment existed.
“There is still a lot of uncertainty about how the IRS will come down on virtual currency,” said Clay Littlefield, a tax attorney for Alston & Bird in Charlotte, North Carolina. “There are some good arguments for why this analogy or that analogy should apply, but there’s not a lot there.”
Enforcement Reality
The enforcement landscape was rapidly shifting beneath the feet of fund managers. Seward & Kissel, a prominent New York law firm specializing in hedge fund law, had launched a dedicated cryptocurrency practice the previous year and was already advising more than two dozen crypto funds by mid-2018, according to tax attorney Brett Cotler.
Many hedge funds set up offshore vehicles in the Cayman Islands or other low-tax jurisdictions for non-U.S. investors. Under normal circumstances, if a fund was operated correctly, income from trading commodities, stocks, or other securities would not trigger the need for a U.S. tax return, nor would foreign investors owe U.S. taxes on their gains.
Crypto funds investing on behalf of foreign investors were acting as though the same rules applied to digital currencies — but neither the IRS nor the courts had confirmed that position. The risk of retroactive tax bills, penalties, and potential enforcement actions loomed large over an industry that was still in its institutional infancy.
The stakes were enormous. Funds structured as pass-through entities needed at least 90 percent of their income to come from qualifying sources to maintain their tax-advantaged status. Whether cryptocurrency trading qualified remained an open question that could determine the viability of entire fund structures.
Market Shockwaves
The tax uncertainty hit an already fragile market. Bitcoin was trading at approximately $6,322 on August 13, 2018, down nearly 65 percent from its all-time high near $20,000 in December 2017. The broader cryptocurrency market had been battered by a series of negative regulatory developments, including the SEC’s decision just days earlier to delay its ruling on the VanEck-SolidX Bitcoin ETF proposal until September 30.
That single SEC delay wiped over $9 billion off Bitcoin’s market value in a matter of hours on August 8, triggering what Bloomberg described as a “sense of panic” among crypto investors. Ethereum had fallen to around $319, with a weekly decline exceeding 22 percent. XRP had dropped below $0.30, losing over 31 percent in seven days.
The combination of the IRS enforcement signal and the SEC’s ETF delay created a double blow to market sentiment. Institutional investors who had been eyeing cryptocurrency as a new asset class were now confronting the reality that the regulatory infrastructure was nowhere near ready to accommodate their participation in a safe, compliant manner.
Closing Thoughts
The IRS crackdown on crypto hedge funds exposed a fundamental tension at the heart of the cryptocurrency market’s institutionalization: capital had moved far faster than regulation. Billions of dollars had flowed into crypto funds without the tax framework needed to support them, and the consequences of that gap were beginning to materialize.
While tax experts urged federal officials to provide clarity, and some guidance was reportedly forthcoming from the Treasury Department’s office of tax policy, the damage to market confidence was already done. For the hedge funds caught in the crosshairs, the choice was stark — proactively amend returns and risk drawing audit attention, or wait and hope that the IRS would eventually issue clear guidelines rather than retroactive penalties.
As Bitcoin continued its slide through the summer of 2018, the tax question served as a stark reminder that the crypto revolution was not just a technological challenge but a regulatory one. And in that arena, the rules were still being written — often after the fact.

84 hedge funds launched in 2017 and the IRS waited until most of them were underwater to start auditing. peak government timing
btc down 55% and your fund is getting audited. 2018 was absolutely brutal for anyone running other peoples money in crypto
ledger_life 55% down and getting audited is actually the best time for IRS because funds have less resources to fight back
wait for the market to crash, then audit. its the oldest enforcement playbook. funds had no cash for lawyers after the january wipeout
audit when funds have no money for lawyers is genuinely sinister when you think about it. enforcement by bankruptcy
no voluntary disclosure program is the worst part. they basically said come clean but we might still prosecute you lol
Paulo Mendes thats exactly why most funds just… didnt report. better to ask forgiveness etc. worked until it didnt
the real issue was that IRS Notice 2014-21 only covered like 3 scenarios. hedge funds doing staking, lending, airdrops had zero guidance
three scenarios for an entire asset class. staking rewards, airdrops, defi yield, all unaddressed until years later. the guidance gap was criminal
three scenarios for an entire asset class is genuinely impressive negligence. staking and airdrops were billion dollar categories with zero IRS guidance
84 funds launched in 2017 and most had no idea how to report crypto gains. the IRS basically set a trap and waited
