The Eleventh Circuit affirmed the district court's grant of summary judgment against a taxpayer for willfully failing to file Foreign Bank and Financial Accounts Reports. However, the court reversed and remanded the portion of the case regarding the constitutionality of the penalties under the Excessive Fines Clause.

Background

Eugene Niksich, a business executive, maintained foreign bank accounts in Switzerland and Panama from 2006 through 2012 without filing required FBARs. He later entered the IRS Offshore Voluntary Disclosure Program but opted out, leading the IRS to assess a penalty of over two million dollars for willful non-compliance. Niksich argued he did not know the reporting requirements applied to his specific assets and that the IRS was estopped from collecting the full penalty after accepting a partial settlement payment.

The court’s reasoning

The Eleventh Circuit applied an objective standard for willfulness, finding that Niksich clearly ought to have known of the risk of non-compliance given his business background and the plain language of his tax returns. The court rejected the affirmative defenses of accord and satisfaction and equitable estoppel, noting that IRS agents lacked the actual authority to bind the government to a settlement and that the taxpayer failed to show the affirmative misconduct required for estoppel. However, the court held that the district court erred in concluding the Eighth Amendment’s Excessive Fines Clause does not apply to civil FBAR penalties, citing the recent decision in United States v. Schwarzbaum.

What it means going forward

Taxpayers facing FBAR penalties can no longer rely on the argument that the Eighth Amendment is inapplicable to civil penalties. The ruling mandates that courts must develop a factual record to determine if specific FBAR penalties are excessive under the Excessive Fines Clause.
