If you’ve read that a court stopped the IRS from collecting foreign corporation reporting penalties, you might wonder whether those penalties still matter. For Americans with overseas businesses, the answer requires more than an old headline.
The litigation over Form 5471 penalties concerns the IRS’s authority to assess particular penalties administratively. It does not eliminate the reporting obligation. And a significant February 2026 appellate decision has strengthened the government’s position.
Understanding the distinction helps you approach a penalty notice with informed questions rather than assumptions about automatic relief.
What Were the Courts Actually Deciding?
The central dispute concerns section 6038(b), which imposes monetary penalties for certain foreign business reporting failures.
“Assessment” is the administrative process through which the IRS records a liability and activates its collection powers. The question was whether Congress authorized that process for section 6038(b) penalties or whether the government needed a federal court judgment instead.
This distinction matters when reading Form 5471 penalty case law. A decision restricting collection procedures does not necessarily mean the underlying statutory penalty disappears.
Farhy: A Taxpayer Victory Followed by Reversal
The Farhy Form 5471 litigation first attracted attention when the Tax Court held in 2023 that the IRS lacked statutory authority to assess the Section 6038(b) penalties.
However, the D.C. Circuit reversed that decision in 2024. It concluded that Congress had made the penalties administratively assessable, examining the statute’s text, structure, and history.
For anyone researching Farhy v Commissioner Form 5471, the appellate outcome is essential. Quoting only the original taxpayer victory leaves out the decision that reversed it.
The practical lesson concerning Form 5471 penalties after Farhy is that the case did not establish a nationwide exemption. Before relying on an article, check which court issued the ruling and whether a later decision changed its effect.
Mukhi: Why the Tax Court Reaffirmed Its Position
The Mukhi Form 5471 dispute involved $120,000 in section 6038(b)(1) penalties for missing Forms 5471 covering 2002 through 2013.
The Tax Court initially ruled for the taxpayer on assessment authority in April 2024. After the D.C. Circuit reversed Farhy, the IRS requested reconsideration. In November 2024, the Tax Court reaffirmed its conclusion that the IRS lacked assessment authority.
Why did Mukhi v Commissioner reach a different result? Its appeal would lie in the Eighth Circuit. At the time, that circuit had no controlling published decision resolving the issue, so the Tax Court was not required to follow the D.C. Circuit’s approach.
That explains why Form 5471 penalties after Mukhi cannot be understood without considering appellate jurisdiction. The November 2024 ruling should also be checked against subsequent appellate developments before being used in a current dispute.
The Important 2026 Development: Safdieh
On February 27, 2026, the Second Circuit decided Safdieh v. Commissioner, No. 25-501.
It held that the IRS may assess section 6038(b) penalties, vacated the Tax Court’s order granting the taxpayer summary judgment, and remanded for further proceedings. The court joined the D.C. Circuit on assessment authority.
This development makes older summaries incomplete if they discuss only Farhy’s original outcome and Mukhi’s reconsideration decision.
The verified appellate picture includes two circuits supporting IRS assessment authority. That does not establish that every possible defense fails or that every taxpayer’s circumstances are identical. The relevant court, penalty provision, and procedural history still need review.
What Financial Exposure Remains?
The IRS’s published instructions continue to describe a $10,000 section 6038 penalty per foreign corporation per annual accounting period for failing to furnish required information.
If the failure continues beyond the prescribed period following IRS notice, additional $10,000 charges can accrue for each 30-day period or fraction, capped at $50,000 in additional penalties per failure.
These cases do not resolve every issue involving section 6046 penalties, foreign tax credit reductions, or other international reporting forms. Avoid treating “Form 5471 penalty” as a single legal category.
What Should You Do with a Penalty Notice?
Start by organizing the facts. Gather the notice, affected returns, filing acknowledgments, extension records, and company ownership documents.
Ask your adviser to identify:
- The statutory provision supporting the penalty.
- The corporations and reporting periods involved.
- Any filing exceptions or reasonable cause arguments.
- The applicable appellate jurisdiction and current precedent.
- The response deadlines and available review procedures.
Keep compliance work moving while those questions are assessed. A legal challenge and correcting missing reporting may require coordinated attention.
