X Fights IRS at Supreme Court: In a landmark legal move with sweeping implications for digital privacy and cryptocurrency users, Elon Musk’s company, X (formerly Twitter), has taken its fight for user data privacy to the United States Supreme Court. The case stems from a long-standing IRS attempt to access Coinbase user data without a warrant, raising critical questions about whether Americans still have meaningful privacy in the digital age. At the heart of the case is a man named James Harper, a former Coinbase user, who claims the IRS violated his constitutional rights by obtaining his financial records without notifying him or giving him a chance to object. X has filed an amicus brief (a legal document filed by a third party to support a case), siding with Harper in his fight for privacy. And the implications are far-reaching—not just for crypto users, but for anyone who uses digital platforms that store sensitive data.
X Fights IRS at Supreme Court
Elon Musk’s X isn’t just waging a legal battle; it’s engaging in a broader fight over the future of privacy in the digital world. As the Supreme Court weighs whether the government can access user data without a warrant, the outcome could shape laws for decades. With platforms like X planning to become digital financial hubs, the stakes are high—not only for companies but for every individual who values their privacy in the age of data.

What Is This Case About?
The case began with the IRS issuing a “John Doe” summons in 2016 to Coinbase, a leading cryptocurrency exchange. The IRS wanted to identify all users who had conducted transactions worth more than $20,000 between 2013 and 2015—without naming any specific individuals or alleging specific wrongdoing.
James Harper, a lawful crypto user who paid his taxes, was swept up in this dragnet. He filed a lawsuit, claiming the IRS violated his Fourth Amendment rights (protection against unreasonable searches) and Fifth Amendment rights (right to due process).
Why Is X Getting Involved?
X’s involvement is both ideological and strategic. Elon Musk has been outspoken about resisting government overreach and censorship. But X also plans to launch its own financial services platform, ‘X Money’, in partnership with Visa. That puts it in a potentially similar position as Coinbase—handling user financial data that could attract regulatory scrutiny.
By standing up for user privacy now, X is also protecting its own future.
A Bit of History: The IRS and Cryptocurrency
The IRS has long struggled to keep up with cryptocurrency’s rapid rise. In 2014, it declared digital currencies like Bitcoin to be property for tax purposes. By 2016, facing a massive tax gap (estimated at $688 billion in 2021, according to the U.S. Treasury), the IRS began aggressively tracking crypto transactions.
The 2016 John Doe summons on Coinbase was one of the agency’s first big moves, affecting over 14,000 users. It marked a shift toward mass surveillance over individualized suspicion, prompting widespread concern among legal experts and privacy advocates.
Breaking Down the Third-Party Doctrine As X Fights IRS at Supreme Court
The IRS’s defense leans heavily on a legal concept known as the third-party doctrine. This rule, established by Supreme Court cases in the 1970s, says that once you voluntarily give your data to a third party—like a bank or a website—you lose your right to privacy over that data.
Critics argue that this doctrine is wildly outdated. In today’s world, nearly every part of life involves sharing data with third parties—whether it’s shopping online, storing photos in the cloud, or trading cryptocurrency.
Legal experts believe this case could force the Court to modernize this doctrine to reflect how digital platforms now function as extensions of our private lives.
International Comparisons: How Other Countries Handle It
The U.S. isn’t alone in facing the privacy vs. enforcement dilemma. Here’s how others approach it:
- European Union: Under the General Data Protection Regulation (GDPR), users have stronger rights over their personal data. Law enforcement must meet strict legal standards to obtain information.
- Canada: Requires a warrant or court order for accessing private user data from digital platforms, as ruled in R. v. Spencer (2014).
- Australia: Allows broader access under its Telecommunications Act, but this has sparked ongoing debate and criticism.
The contrast highlights how far behind the U.S. may be in digital rights protections, especially as new technologies emerge.
What Happens If Harper Wins?
If the Supreme Court sides with Harper, the ruling could:
- Limit the IRS’s ability to issue blanket data requests
- Reinforce the need for individualized warrants
- Prompt Congress to update outdated privacy laws
- Empower platforms like X to resist overbroad data demands
Such a decision could ripple across industries—from fintech to social media, healthcare, and beyond—reshaping how digital companies handle and protect user data.
What Can You Do to Protect Your Privacy?
While the courts decide, here are a few steps you can take now to protect your digital financial data:
- Use Privacy-Oriented Platforms: Opt for services with strong encryption and clear privacy policies.
- Limit Shared Data: Only provide essential information when creating accounts.
- Enable Two-Factor Authentication: This adds an extra layer of security against unauthorized access.
- Review Your Platform Settings: Most exchanges and financial platforms let you manage data-sharing preferences.
- Stay Informed: Monitor developments in digital rights. Websites like EFF and EPIC offer valuable resources.
Expert Opinions: What Legal Scholars Say
Leading privacy attorney Alan Butler, Executive Director of the Electronic Privacy Information Center (EPIC), commented:
“This case is a perfect example of how old legal rules don’t fit the digital age. The Supreme Court has a chance to correct course and reinforce core constitutional values.”
Even some conservative legal scholars agree. The Pacific Legal Foundation, a libertarian law group, filed a brief supporting Harper. They argue that allowing warrantless access “effectively nullifies Fourth Amendment protections” in the digital realm.

Frequently Asked Questions About X Fights IRS at Supreme Court
Q: What is X’s legal argument?
X argues that the government’s actions violate user privacy rights and lack judicial oversight, setting a dangerous precedent for all digital platforms.
Q: Can the IRS still get user data from Coinbase?
Yes, but only under current laws. If Harper wins, those laws may need to be updated or reinterpreted.
Q: How does this affect me if I don’t use Coinbase?
The outcome could impact any digital platform you use, including social media, cloud storage, and online banking.
Q: Will this stop all government access to data?
No. The government could still access data—but only with proper judicial oversight, like a warrant.
Future Outlook: What’s Next?
The Supreme Court has not yet decided whether it will hear the case, but the growing number of amicus briefs—including from X, privacy groups, and scholars—suggests strong national interest.
If accepted, the ruling could come by late 2025. Until then, the debate will continue to shape public opinion, corporate policy, and potentially, congressional reform.
