I posted much of the information in this blog entry at the bottom of the immediately preceding blog: Fifth Circuit Knows a Limited Partner When Reads It (1/24/26; 1/27/26), here. I decided that the information should not be buried in the prior blog but should be lifted into it’s own blog entry. So here it is. For context, yesterday’s blog was about the Fifth Circuit’s opinions in Sirius Solutions, L.L.L.P v. Commissioner, ___ F.4th ___ (5th Cir. 2025), CA5 here and GS here, which held that the limited partner exception in § 1402(a)(13) does not apply to earnings allocated to a nominal limited partner even though providing services to a limited partnership. Please note that I bold-faced exception because that the majority and the dissenting opinions agree it is an exception to the general rule of taxation. (In view of this blog entry, I have eliminated the information from the bottom of the prior blog entry.)
I ask readers to consider
seriously footnote 8 of the majority Sirius majority opinion spanning Slip Op. 23-24):
n8 Even if the IRS and Tax Court’s arguments had persuasive authority, they would at most establish ambiguity. But that is not enough for the Government’s passive investor rule to prevail. It is a “longstanding canon of construction that if the words of a tax statute are doubtful, the doubt must be resolved against the government and in favor of the taxpayer.” United States v. Marshall, 798 F.3d 296, 318 (5th Cir. 2015) (quotation omitted).
First, Loper Bright claims (I think nonsensically) that courts can always interpret out ambiguity in the statute. See e.g., Chevron, Loper Bright, and Statutory Ambiguity (Federal Tax Procedure Blog 1/8/26; 1/9/26), here. If there is genuine ambiguity where the court is unable to determine the best interpretation between two or more interpretations within the zone of ambiguity, the court will need a tie-breaker which artificially resolves the ambiguity to decide the case. Chevron offered such a tie-breaker, but Loper Bright rejected Chevron without substituting any other tie-breaker. Of course, the alleged "longstanding canon of construction the majority claims in footnote 8 could supply a tie-breaker in the majority's imagination. I address here the validity of the majority's claim of this "pro-taxpayer" canon of construction.
Canons of statutory construction are “rules of thumb that help courts determine the meaning of legislation.” They are said to “limit judicial discretion and render statutory meaning more predictable.” E.g., Jonathan H. Choi, The Substantive Canons of Tax Law, 72 Stan. L. Rev. 195, 228-229 (2020), here. On the other hand, they are said to be “readily manipulable and [frustrate] the policy preferences of Congress.” Karl Llewellyn famously observed that “there are two opposing canons on almost every point.”
A variation on the theme is that maxims, which may function like canons, might be viewed as minims because they reveal so little and are "singularly unhelpful when it comes to deciding cases." United States v. Ingredient Technology Corp., 698 F.2d 88, 94 (2d Cir. 1983)
Professor Choi notes that the opposing canon (called an anti-taxpayer canon) is to construe exemptions from tax against the taxpayer who cannot show that the statute requires the exemption. (See Choi, pp. 251-254.) Furthermore, Choi notes that the pro-taxpayer canon is not now in vogue. (See Choi, pp. 253-254, quoting Scalia and Garner arguing for applying the fair meaning of statutes; in any event, the anti--taxpayer rule for tax exemptions, "has been sufficiently widely validated and cited that, in my view, its place among the substantive canons is secure" and "the courts have widely embraced this canon." So, the mere fact that the majority felt the need, albeit in a footnote, to use the dubiously applicable pro-taxpayer canon instead of a fair meaning of the statutory exemption or the anti-taxpayer rule, is suspect.
