FBAR Penalties

A non-willful FBAR violation carries a civil penalty of up to $16,536 per unfiled report, adjusted for inflation. A willful violation raises that ceiling to $165,353, or to half the unreported account balance if larger, assessed separately for each account and each year. Criminal prosecution is also available. Under the Supreme Court’s 2023 decision in Bittner v. United States, the non-willful penalty applies per report, not per account.

An assessed FBAR penalty becomes a federal debt with collection powers no private creditor has: offset of tax refunds and Social Security payments, a Justice Department collection suit, and a judgment enforceable nationwide. For Cook Islands trust grantors, whose foreign trust accounts are reportable every year, these rules measure the real cost of a missed filing.

FBAR Penalty Amounts by Violation Type

Four penalty levels apply to unfiled FBARs, each with its own dollar cap and its own unit of assessment.

• Non-willful violation. Up to $16,536 for each unfiled annual report, no matter how many accounts the report should have listed. Reasonable cause can eliminate the penalty when the account balance was also properly reported.
• Willful violation (civil). A ceiling of $165,353, or 50 percent of each unreported account’s balance if that is larger, assessed separately, account by account and year by year.
• Criminal violation. A fine of up to $250,000, up to five years in prison, or both.
• Criminal violation combined with other crimes. A fine reaching $500,000 and a ten-year maximum sentence when the failure accompanies another federal offense or a twelve-month run of illegal activity above $100,000.

The dollar figures are inflation adjustments to statutory base amounts of $10,000 and $100,000, so the civil maximums rise with inflation over time. The penalties attach to the FBAR filing obligation itself, which applies whenever a U.S. person’s foreign financial accounts exceed $10,000 in aggregate during the year.

FinCEN’s August 2026 final rule ended beneficial ownership reporting for U.S. companies and U.S. persons. Settlors sometimes take that to mean both FinCEN filings went away. Only the corporate transparency report did. The FBAR remains due every year the trust’s foreign accounts exceed the $10,000 threshold.

Non-Willful Penalties After Bittner v. United States

Non-willful FBAR penalties are calculated per unfiled annual report, no matter how many foreign accounts the missing report should have disclosed. Alexandru Bittner, a dual citizen who returned to the United States after years abroad, failed to file FBARs covering 272 accounts across five years. The government sought $2.72 million by counting each account as a separate violation. In 2023 the Supreme Court held that the statute penalizes the failure to file a report, so Bittner owed at most five penalties totaling $50,000.

The per-report rule limits exposure for trust structures in particular. A typical Cook Islands trust holds accounts at a trustee bank, a brokerage custodian, and sometimes an offshore LLC’s separate bank. One missed year produces one non-willful penalty, not three or more. Missed years still stack: five unfiled years at current rates is $82,680 in maximum exposure.

Assessment is discretionary. The statute sets a maximum and leaves the amount to the examiner, who can assess less.

What Makes an FBAR Violation Willful?

Willfulness in FBAR law extends beyond deliberate concealment to reckless disregard of the filing duty. Courts have upheld willful penalties against filers who never set out to hide anything but ignored clear signals that a filing was due. The recurring example is a signed tax return whose Schedule B answers “No” when it asks whether foreign accounts exist. That signature puts the filer on notice, and courts treat proceeding without inquiry as recklessness.

The classification carries most of the financial consequence. Willful penalties are assessed per account and per year, so a grantor who willfully fails to file for three years while holding $500,000 across unreported accounts faces potential penalties of $750,000, more than the accounts contain. Since Bittner capped non-willful exposure, the IRS has more reason to press for willful classification in large-balance cases.

IRS letters about offshore accounts usually trace to a mismatch rather than to the account itself. The bank’s FATCA report shows an account the filer’s return never mentioned. Often a change of tax preparers left the new CPA unaware the trust existed. A grantor whose own filings match what the bank reports gives the IRS nothing to chase.

When FBAR Violations Become Criminal

Criminal FBAR prosecution requires willfulness plus aggravating conduct, and it is rare compared with civil assessment. The base offense carries a fine reaching $250,000, five years in prison, or both. Those maximums double, to $500,000 and ten years, when the filer simultaneously breaks another federal law, or when the failure joins a pattern of illegal acts exceeding $100,000 within twelve months. Prosecutors almost always pair an FBAR count with tax evasion, false return, or money laundering charges. An unfiled form standing alone is handled civilly.

The Excessive Fines Limit in United States v. Schwarzbaum

The Eleventh Circuit held in 2025 that willful FBAR penalties are fines subject to the Eighth Amendment’s Excessive Fines Clause, the first federal appeals court to say so. Isac Schwarzbaum owed a $12.5 million judgment for willful penalties on Swiss accounts. The court struck $300,000 of the total: three years of $100,000 statutory-maximum penalties on one account that never held more than $16,000, a penalty at least six times the account’s peak balance. The remaining $12,255,813 stood, because taking 50 percent of a multimillion-dollar balance is not grossly disproportionate to concealing it.

The ruling conflicts with the First Circuit’s 2022 decision in United States v. Toth, which the Supreme Court declined to review, so the constitutional limit depends today on where the filer litigates. The government did not ask the Supreme Court to review the Eleventh Circuit’s ruling. In the decided cases, proportionality review trims statutory-maximum penalties on small accounts and leaves percentage-based penalties on large accounts intact.

How the Government Collects an FBAR Penalty

The government collects FBAR penalties through offsets and lawsuits rather than through the tax collection machinery. The penalty arises under the Bank Secrecy Act, not the tax code, and the difference controls collection. No federal tax lien attaches. The IRS cannot levy a bank account or garnish wages administratively, and no collection due process hearing exists because the tax procedures do not apply.

What the government can do immediately is offset. Once the penalty is assessed, the Treasury can redirect the filer’s tax refunds, Social Security payments, and other federal payments against the debt, with interest and a late-payment penalty accruing on the unpaid balance.

The rest runs on a two-stage clock. The IRS must assess the penalty within six years of the violation, measured from the missed filing deadline. After assessment, the government has two years to file a collection suit in federal district court. The suit is the government’s only path to the filer’s other assets, and it is where the penalty defenses of willfulness, reasonable cause, and excessiveness get litigated.

What an FBAR Penalty Judgment Lets the Government Do

A judgment on an FBAR penalty makes the United States a stronger creditor than any private plaintiff. Collection proceeds under the Federal Debt Collection Procedures Act. The statute gives the government nationwide enforcement from a single court, adds a 10 percent surcharge covering litigation costs, and lets government lawyers unwind transfers made to defeat collection. A private judgment creditor must domesticate its judgment state by state and live with each state’s exemption law. The United States litigates once and collects everywhere.

The debt also outlasts the debtor. In United States v. Hendler, a New York federal court held in 2024 that FBAR liability accrues on the missed filing deadline and survives the filer’s death, so the government could pursue the penalties against the estate. A government penalty that does not compensate for a monetary loss is generally excepted from an individual’s Chapter 7 discharge.

How the Reasonable-Cause Defense Works

Reasonable cause excuses a non-willful FBAR violation when the filer exercised ordinary business care and still failed to file. The statute imposes two conditions: the failure must rest on reasonable cause, and the account balance or transaction amount must itself have been properly reported. The second condition is the narrow one. Paying tax on the account’s interest is not the same as reporting its balance, so income reporting alone does not open the exception.

In practice the defense turns on what the filer knew and what the filer did. A CPA’s involvement is not by itself reasonable cause. In Jarnagin v. United States, a couple holding millions in a Canadian bank lost the defense although the court assumed their accountants already knew about it. They had signed returns they never read, missing a Schedule B answer that wrongly denied any foreign account. Forgetting the deadline, finding the rules complicated, or assuming a preparer handled the filing does not qualify.

The filers who win reasonable-cause arguments documented their diligence while it was happening. They disclosed the accounts to their preparer and asked about foreign reporting, and they kept the answers in writing.

An FBAR can still be filed after its deadline. A CPA handles late filings, with a tax controversy attorney involved where willfulness is in question.

Can a Cook Islands Trust Protect Assets from an FBAR Penalty?

A Cook Islands trust that was funded and reported years before any FBAR problem arose is difficult for the government to reach. A trust funded after a penalty assessment invites fraudulent transfer claims and a repatriation order, and the transfer itself can become evidence of willfulness.

Timing decides the analysis. The federal fraudulent transfer provisions reach transfers made to hinder collection of a federal debt, and a funding transfer that follows an assessment sits squarely inside them.

The government also does not need to chase assets abroad to win. In the Schwarzbaum collection litigation, the court ordered the debtor in 2023 to repatriate enough Swiss funds to satisfy the judgment. The order rested on personal jurisdiction over the debtor rather than any power over the Swiss banks. Courts enforce such judgments through turnover and repatriation orders directed at the person, and refusal is contempt, with incarceration available until the money returns.

Schwarzbaum stayed in Switzerland and repatriated nothing, and the court held him in civil contempt in 2023. In May 2026 it ruled that he can be jailed until he complies and ordered that a warrant issue for his arrest. The court also referred him to the U.S. Attorney, who decides whether criminal contempt charges follow. As of August 2026 the court record showed no repatriation and no recovery on the judgment.

The timing rules for federal penalty debts are narrower than for private litigation. Cook Islands trusts can be established after a private lawsuit has been filed, with the trust deed drafted to manage the fraudulent transfer exposure. An assessed federal penalty is the weak case. The creditor is the United States, and courts have held that the penalty survives the account holder’s death. An existing IRS debt raises the same planning limits, because a federal tax lien attaches to property the moment the tax is assessed.

Penalty defense for someone who already owes an assessed FBAR penalty belongs with a tax controversy attorney. Funding a trust against an existing federal assessment adds contempt and criminal exposure without removing the debt. Offshore planning fits people facing private claims: lawsuits, malpractice exposure, and personal guarantees.

For a grantor whose filings are current, an FBAR penalty never arises. Every account appears in the grantor’s own filings and in the bank’s FATCA report, and no assessment ever exists for the government to collect. Annual reporting for a Cook Islands trust runs on a fixed calendar of IRS and FinCEN filings that keeps the structure transparent while its protection stays in place.
