TL;DR

A California federal judge dismissed Roger Metz’s attempt to quash an IRS summons to Coinbase after finding a fatal service error.
The court never ruled on Metz’s privacy and overbreadth claims because he failed to notify the US Attorney General within 90 days.
The decision reinforces how hard it remains to block IRS access to exchange records as 1099-DA reporting moves crypto tax enforcement closer to automation for US investors.

A California court has handed the IRS another procedural win in its effort to reach crypto records held by centralized exchanges. The ruling did not test the privacy argument, but it still changed the balance of the fight. Judge Araceli Martínez-Olguín dismissed a petition from Coinbase user Roger Metz, who had sought to block an IRS summons for his transaction records during an audit of his 2022 federal tax return. Metz argued the request was overbroad, unnecessary and invasive, but the court never reached those substantive claims because the case failed on service requirements alone.

Why the Coinbase Case Matters Beyond One User

The outcome turned on a narrow but decisive legal defect. A missed notice deadline ended the challenge before the court addressed the summons itself. Metz filed his petition in May 2025 and properly served the local US Attorney and the IRS, but he failed to notify the US Attorney General in Washington within the required 90-day window. According to the ruling, he also offered no persuasive explanation for that omission. The court therefore concluded dismissal was appropriate for insufficient service of process, leaving the IRS summons intact and the privacy dispute unresolved in federal court.

The dismissal lands inside a much larger legal pattern. Crypto users are still running into the same third-party doctrine wall. The report says federal courts continue to rely on the principle that people generally lack Fourth Amendment privacy protections over records held by financial institutions. That framework has made it difficult for crypto users to stop the IRS from obtaining exchange data through John Doe summonses and related tools. The decision also echoes the failed challenge brought by James Harper, whose privacy battle ultimately went nowhere after the Supreme Court declined review earlier this year.

For US investors, the message is becoming harder to miss. Exchange data is moving closer to automatic tax visibility, whether users like it or not. The IRS has used summons powers since 2016 to compel firms such as Coinbase, Kraken and Circle to turn over customer information. That pressure may soon intensify through formal reporting channels rather than courtroom fights. Starting in 2026, Form 1099-DA is set to require digital asset brokers to report proceeds directly to the IRS. As that framework expands, procedural defenses and exchange-based privacy assumptions appear increasingly weak for taxpayers now.
