U.S. Supreme Court Ruling Supports IRS Use of Crypto Data from Exchanges

The U.S. Supreme Court has decided not to take up a closely watched crypto privacy case, effectively leaving in place earlier rulings that support the IRS’ authority to access bitcoin user data without the user’s knowledge or consent. Bloomberg was among the outlets to report on the Court’s decision, which ends a legal battle over how far government agencies can go when gathering information from crypto platforms.

Good to know

• The case challenged the IRS’ use of a John Doe summons to collect crypto data.
• The Supreme Court’s denial leaves earlier court decisions untouched.
• The IRS can continue accessing crypto user info shared with exchanges.

James Harper, a former user of Coinbase, Abra, and Uphold, filed the original lawsuit after receiving a letter from the IRS in 2019 about his crypto activity. Harper claimed he had fully reported and paid taxes on his holdings, and was surprised to learn the agency had obtained his account data without any direct notice.

That information was collected through a 2016 “John Doe” summons issued to Coinbase, which sought details on users who transacted over $20,000 between 2013 and 2015. Harper’s lawsuit argued that the IRS violated his Fourth and Fifth Amendment rights and failed to follow proper legal procedures outlined in the tax code and the Administrative Procedure Act.

After losing in both the U.S. District Court and the First Circuit Court of Appeals, Harper filed a petition asking the Supreme Court to weigh in. On June 30, the Court declined the request. That leaves the lower courts’ rulings intact, including conclusions that Harper had no legal expectation of privacy in records shared with exchanges and that the IRS’ action was not subject to judicial review under the APA.

At the heart of the case was a broader concern: do individuals still have privacy rights over data they share with digital platforms? The current legal standard—the “third-party doctrine”—says no. According to this view, once users give their information to a third party, like a crypto exchange, they lose their constitutional protections over that data.

Critics say that logic feels outdated in a digital age where financial and personal data is routinely stored online and shared across multiple services. Though Harper’s legal battle has reached its end, the larger debate over data privacy in the crypto space is likely to continue in courtrooms and policy circles alike.

So, will lawmakers and regulators catch up to how people actually use digital platforms—or will privacy keep taking a backseat?
