Siemens Medical Solutions USA, Inc. & Consolidated Subsidiaries v. Commissioner, 167 T.C. No. 5 (2026)

In Siemens Medical Solutions USA, Inc. and Consolidated Subsidiaries v. Commissioner of Internal Revenue, 167 T.C. No. 5 (2026), the United States Tax Court addressed a critical conflict between the plain text of the Internal Revenue Code (IRC) and the administrative regulations promulgated by the Department of the Treasury. The case centered on the validity of Temporary Treasury Regulation § 1.245A-5T, specifically the "Extraordinary Disposition Rules," which limited the 100% dividends-received deduction (DRD) enacted under the Tax Cuts and Jobs Act (TCJA). This article provides a technical analysis of the case's facts, the taxpayer's request for relief, the court's statutory analysis, and the broader implications for tax professionals in the post-Loper Bright era.

Factual Background and the Restructuring Transactions

The petitioner, Siemens Medical Solutions USA, Inc., is a wholly owned subsidiary of Siemens Healthineers AG (SHAG), a German company that provides healthcare products globally. At all relevant times, Siemens Healthcare Diagnostics, Inc. (SHD US), a California corporation and member of the petitioner’s U.S. consolidated group, owned 67.78% of Siemens Medical Solutions Diagnostics Holding I.B.V. (SMS BVI), a Dutch company treated as a corporation for U.S. federal income tax purposes.

During the taxable year ended September 30, 2018, certain foreign subsidiaries of SMS BVI were restructured. On April 1, 2018, SMS BVI sold 100% of Siemens Healthcare Diagnostics GmbH (a Swiss company) for €85,715,399 to Siemens Healthineers Holding III BV, a Dutch company within the SHAG Group. Subsequently, on August 13, 2018, SMS BVI sold 100% of Siemens Healthcare Diagnostics Holding GmbH (a German company) to Siemens Healthcare GmbH (a German company within the SHAG Group) for €1,339,593,000. As a result of these two sales, SMS BVI increased its earnings and profits (E&P) by approximately €819,000,000.

On March 19, 2019, SMS BVI made a pro rata distribution of €1,750,000,000 to its shareholders. Because SHD US owned 67.78% of SMS BVI, it received €1,186,073,740, of which $670,616,109 was a dividend made out of SMS BVI's E&P (the March 2019 Dividend). This March 2019 Dividend was entirely foreign-source income.

The Statutory Mismatch and Regulatory Overlay

The TCJA included several interrelated provisions designed to transition the United States from a worldwide tax system to a partially territorial system, primarily IRC § 245A (the DRD), IRC § 965 (the Mandatory Repatriation Tax or MRT), and IRC § 951A (the GILTI regime).

Section 245A allows a 100% deduction for the foreign-source portion of dividends received from a specified 10-percent owned foreign corporation by a domestic corporate shareholder, effective for distributions made after December 31, 2017.
Section 965 (MRT) is a one-time transition tax on accumulated foreign earnings of foreign corporations measured as of November 2, 2017, or December 31, 2017.
Section 951A (GILTI) taxes prospective foreign earnings for taxable years of foreign corporations beginning after December 31, 2017.

Because these provisions had varying effective dates, a "gap" arose for certain fiscal-year taxpayers. For SMS BVI, whose fiscal year ended on September 30, a "disqualified period" existed from January 1, 2018, to September 30, 2018. During this gap, SMS BVI's earnings from the intercompany restructuring sales were not subject to the MRT (since they accrued after December 31, 2017) and not subject to GILTI (since SMS BVI's post-TCJA fiscal year had not yet begun), yet distributions of those earnings were literally eligible for the 100% DRD under § 245A.

To address this effective date gap, the Treasury and the IRS issued Temporary Treasury Regulation § 1.245A-5T. The preamble explained that these regulations aimed to target transactions that inappropriately converted income that should have been subject to U.S. tax into nontaxed income. The temporary regulation implemented the "Extraordinary Disposition Rules," which disallowed 50% of the section 245A deduction for dividends paid out of an "extraordinary disposition account". An extraordinary disposition was defined as a sale of specified property to a related party, outside the ordinary course of business, during the foreign corporation's disqualified period while it was a CFC.

Taxpayer's Claimed Deduction and Request for Relief

The petitioner timely filed consolidated federal income tax returns for its 2019 Tax Year, claiming a deduction for the full amount of the March 2019 Dividend under § 245A. While the petitioner acknowledged that the 2018 sales likely met the definition of "extraordinary dispositions" under Temp. Treas. Reg. § 1.245A-5T, it concluded that the Extraordinary Disposition Rules were invalid as a matter of law. Accordingly, the petitioner filed Form 8275-R, Regulation Disclosure Statement, disclosing the relevant facts and its legal analysis.

The Commissioner issued a Notice of Deficiency, disallowing $314,992,962 of the § 245A deduction and asserting deficiencies of $5,581,518 for the 2019 Tax Year and $1,452,006 for the 2021 Tax Year. The petitioner petitioned the Tax Court and moved for Summary Judgment, arguing that it was entitled to the full deduction under the plain terms of § 245A and that the regulation was invalid. The Commissioner cross-moved for summary judgment, contending that the Extraordinary Disposition Rules were a valid exercise of Treasury's broad authority under § 245A(g) to prescribe "necessary or appropriate" regulations and under § 7805(a) to prescribe "all needful rules and regulations".

The Court's Analysis of the Law and Primacy of Plain Statutory Text

The Tax Court, in an opinion written by Judge Kerrigan and reviewed by the full court, began its analysis with the foundational maxim "that courts must presume that a legislature says in a statute what it means and means in a statute what it says there" (quoting Varian Med. Sys., Inc. & Subs. v. Commissioner, 163 T.C. 76, 87 (2024), quoting Conn. Nat'l Bank v. Germain, 503 U.S. 249, 253–54 (1992)).

The court carefully applied the plain language of § 245A to the facts:

The distribution was made in March 2019, which is after the December 31, 2017 effective date of § 245A.
The dividend was paid by a "specified 10-percent owned foreign corporation" of which a member of the petitioner's consolidated group (SHD US) was a U.S. shareholder.
The dividend was paid out of foreign earnings, representing the "foreign-source portion" of the distribution.

Because all elements of § 245A were met, the court agreed with the petitioner that "under the plain terms of section 245A it was entitled to the entire deduction".

The court then addressed the head-to-head conflict between the statute and the temporary regulations. Judge Kerrigan observed that the Treasury's regulation "disallows 50% of the deduction for distributions that Treasury admits satisfy the plain terms of the statute, using criteria that appear nowhere in the statute". She declared that "this creates a contradiction, and the statute must prevail".

The court cited In re Complaint of Nautilus Motor Tanker Co., 85 F.3d 105, 111 (3d Cir. 1996), noting it is "axiomatic that federal regulations can not ‘trump’ or repeal Acts of Congress". Under Tax Court precedent, the "Commissioner’s regulations ‘cannot change the result dictated by an unambiguous statute’" (quoting Abdo v. Commissioner, 162 T.C. 148, 168 (2024), citing Niz-Chavez v. Garland, 141 S. Ct. 1474, 1485 (2021)).

The Limits of Regulatory Authority Post-Loper Bright

The Commissioner argued that the regulation fell within the "necessary or appropriate" delegation under § 245A(g). However, the court countered that post-Loper Bright Enterprises v. Raimondo, 144 S. Ct. 2244 (2024), the reviewing court’s role under the Administrative Procedure Act is "to independently interpret the statute and effectuate the will of Congress subject to constitutional limits". This requires "recognizing constitutional delegations, ‘fix[ing] the boundaries of [the] delegated authority,’ . . . and ensuring the agency has engaged in ‘“reasoned decisionmaking”’ within those boundaries" (quoting Loper Bright, 144 S. Ct. at 2263).

Under Loper Bright, "statutes, no matter how impenetrable, do—in fact, must—have a single, best meaning" and "every statute’s meaning is fixed at the time of enactment" (quoting Loper Bright, 144 S. Ct. at 2266). While the Commissioner argued that the word "appropriate" is context-dependent, the court explained that "context does not help respondent" because "Treasury is not trying to construe the language of section 245A. Instead, Treasury is trying to correct the mismatch in effective dates by changing the plain meaning of the statute".

The court noted that the mismatch in effective dates was a product of explicit choices made by Congress. The House and Senate versions had different effective date provisions, and Congress chose to adopt the "distributions made after December 31, 2017" rule for § 245A. The court emphasized: "Congress could have chosen for section 245A and section 951A to have the same effective dates. Congress chose not to do so... and we will respect the choice that Congress made".

Consequently, the court ruled that "Treasury, not Congress, was concerned" about the tax-free gap, and "Treasury, not Congress, decided unilaterally to approximate the tax treatment of the MRT and the GILTI by disallowing 50% of the section 245A deduction". Citing Utility Air Regulatory Group v. EPA, 573 U.S. 302, 328 (2014), the court reiterated that "an agency may not rewrite clear statutory terms to suit its own sense of how the statute should operate".

Conclusion and Professional Takeaways

The Tax Court held that the petitioner is entitled to the full DRD under I.R.C. § 245A, and that Temp. Treas. Reg. § 1.245A-5T does not alter this conclusion because it cannot contravene the clear statutory text. Because "the Extraordinary Disposition Rules were never contemplated by the statutory text," they fall outside the boundaries of any regulatory authority delegated to the Treasury under § 245A(g) or § 7805. Accordingly, the court granted the petitioner’s Motion for Summary Judgment and denied the Commissioner's Cross-Motion.

For CPAs and EAs, Siemens v. Commissioner stands as a monumental confirmation of statutory literalism in corporate tax practice. It signals a clear boundary for Treasury: administrative agencies cannot rewrite unambiguous statutory effective dates or draft substantive limitations to repair perceived loopholes under the guise of "necessary or appropriate" rulemaking. Following the Supreme Court's rejection of Chevron deference in Loper Bright, tax professionals can confidently rely on the plain meaning of the Internal Revenue Code when administrative regulations seek to impose extra-statutory limitations.
