Bittner v. United States (2023)

The non-willful FBAR penalty applies per report, not per account.

The case in brief

  • Citation: Bittner v. United States, 598 U.S. 85 (2023), decided February 28, 2023.
  • Question: When a person does not willfully fail to file an FBAR, is the maximum penalty $10,000 per report or $10,000 per foreign account listed on it?
  • Holding: Per report. The Bank Secrecy Act's non-willful penalty attaches to the failure to file a compliant annual report, not to each account.
  • Vote: 5–4. Justice Gorsuch wrote for the majority; Justice Barrett dissented, joined by Justices Thomas, Sotomayor and Kagan.

The facts

  • Alexandru Bittner, a dual U.S.–Romanian citizen, did not timely file FBARs for 2007 through 2011.
  • The government counted each account on each late report — 272 in total — and sought $2.72 million in non-willful penalties.
  • Under the Court's per-report reading, the maximum was $50,000: five late reports at $10,000 each.

Why it matters

  • For non-willful cases, exposure is now driven by the number of years, not the number of accounts — a large difference for people with many small foreign accounts.
  • The decision does not change willful penalties, which can reach the greater of $100,000 or 50% of the account balance (both amounts adjusted for inflation) per violation.
  • Reasonable cause remains a full defense to the non-willful penalty, and the Streamlined procedures remain available to eligible non-willful taxpayers.
