The United States Court of Federal Claims ruled on October 15, 2026, in the case of Transupport, Inc. v. United States, dismissing a tax refund claim brought by Transupport. The court found that Transupport did not meet the necessary jurisdictional requirements to file its claim. This decision affects Transupport, a global supplier of turbine engine parts, and highlights the importance of procedural compliance in tax matters.

Transupport sought a refund of $887,956 in taxes paid for the 2017 tax year, arguing that it had incurred significant losses in the following year, 2018. However, the court determined that Transupport's claim for a refund was not valid due to a lack of jurisdiction, as it had not filed a claim for a refund with the IRS before bringing the lawsuit. This ruling underscores the critical nature of following proper procedures when dealing with tax refunds.

Background

Transupport, Inc. is a company that supplies turbine engine parts globally. The dispute arose from a series of IRS audits spanning several years, which revealed that Transupport had undervalued its inventory, leading to underreported taxes. The IRS audited Transupport for tax years 1999 to 2008 and determined that the company had significantly understated its inventory values. This led to a Tax Court case, where the IRS's valuation was ultimately upheld by the First Circuit Court of Appeals in 2018.

Following the audits, Transupport continued to report its inventory at a value of approximately $3 million for tax purposes until 2018, when it filed its first tax return for that year. In this return, Transupport reported an inflated beginning inventory value of $28,900,953, which was inconsistent with its previous valuations. This discrepancy raised concerns during subsequent IRS audits, leading to further complications.

In 2022, Transupport entered into a settlement agreement with the IRS regarding its tax liabilities for the years 2015 to 2017, stipulating to a deficiency of $887,956 for 2017. After filing amended tax returns for 2017 and 2018, Transupport sought to carry back losses from 2018 to offset its 2017 tax liability. However, the IRS denied this request, prompting Transupport to file a lawsuit in the Court of Federal Claims in February 2025.

The Ruling

The court, presided over by Judge Molly R. Silfen, ruled in favor of the United States government, granting its motion for summary judgment on the breach of contract claim and dismissing the tax claim for lack of subject-matter jurisdiction. The court stated, "Transupport has not satisfied the jurisdictional prerequisites for filing a tax claim in this court and cannot prove any breach of contract." The ruling emphasized that Transupport failed to file a claim for a refund with the IRS before bringing its case to court, a requirement for jurisdiction.

Furthermore, the court noted that Transupport's amended tax return did not constitute a valid claim for a refund because it was filed after the IRS had already assessed the tax deficiencies. The court did not address the merits of Transupport's claims, as the jurisdictional issues were sufficient to dismiss the case.

Impact

This ruling has significant implications for Transupport and other taxpayers seeking refunds from the IRS. It reinforces the necessity of adhering to procedural requirements when filing tax claims. Taxpayers must ensure that they have filed a claim for a refund with the IRS before pursuing legal action in federal court. This case serves as a reminder that failing to follow proper procedures can result in the dismissal of legitimate claims.

Additionally, the ruling may set a precedent for similar cases in the future, emphasizing the importance of jurisdictional compliance in tax matters. Taxpayers must be aware of the requirements set forth by the IRS and the courts to avoid potential pitfalls in their claims.

What's Next

Transupport may consider appealing the court's decision, but it would need to demonstrate that it met the jurisdictional requirements for its tax refund claim. There is no indication of any related cases pending that could impact this ruling.
