Discussion Board Forum 1: The Authority of Treasury Regulations After Loper Bright

ACCT 612 Tax Research and Jurisprudence, Discussion Board Forum 1

Thread by [Student Name]

The classmates are composites; the cases, regulations and scholarship cited are real.

A client's position depends on a Treasury regulation that interprets an ambiguous Code section in the client's favor, while the IRS's position depends on another reading. How much should the research memo rely on the regulation? Sawyers and Gill (2018) place Treasury regulations near the top of the administrative authority hierarchy, just below the Code itself, and for a generation the answer was straightforward. Under Chevron, a court facing an unclear statute would accept any reasonable reading the agency had adopted, and in Mayo Foundation for Medical Education & Research v. United States (2011), the Supreme Court held that Treasury regulations received the same deference as any other agency's rules. Treasury regulations were not singled out for special treatment; the Court rejected the idea that tax law required its own, less deferential test, and lower courts applied Chevron's two steps to regulations for more than a decade.

That changed in Loper Bright Enterprises v. Raimondo (2024), which overruled Chevron and held that courts must exercise independent judgment in deciding whether an agency acted within its statutory authority. An agency's reading can still persuade a judge, but they decide the best reading of the statute themselves. The decision did not say that every regulation upheld under Chevron is now invalid; the Court stated that earlier cases relying on Chevron remain good law under statutory stare decisis, so a regulation already sustained by the Supreme Court stands until revisited. Jackson and Pippin (2025) expect significant repercussions for tax policy, the IRS's interpretations and the Tax Court, since many regulations were sustained under the old framework. A regulation is no longer the last word on an ambiguous statute; it is a strong argument about what the statute means.

Two limits keep the change from being as dramatic as it sounds. The statute still controls, and where Congress expressly delegated authority to Treasury to fill in details, a court reviews whether the regulation stays within that grant, not whether it is the best reading. Schnee and Seago (2012), writing after Mayo, explained how the two-step Chevron analysis applied to Treasury pronouncements; much of that analysis about statutory clarity remains useful as a starting point. My working rule is that a researcher should treat a regulation as strong but contestable authority, check whether the statute is clear on its own and whether the regulation rests on a specific delegation, and tell the client plainly when the position depends on a regulation a court could now reject. In practice, that means reading the statute first, then the regulation, then any cases that tested it, and stating the risk level in the memo's conclusion rather than burying it in the analysis.

Rebecca, your thread pointed out that after Loper Bright different courts may read the same Code section differently, and I agree that this makes forum choice more important. The choice of forum, Tax Court, district court or Court of Federal Claims, already mattered before 2024. One rule from the judicial sources chapter shapes the analysis. Under Golsen v. Commissioner (1970), the Tax Court follows the precedent of the court of appeals to which an appeal would lie, so a taxpayer's circuit can determine the outcome even in the Tax Court. The rule exists to avoid a Tax Court decision that the appellate court would simply reverse. Sawyers and Gill (2018) explain that this is why a researcher must check circuit precedent, not just Tax Court decisions. After Loper Bright, a circuit that has already rejected a regulation's reading will bind the Tax Court for taxpayers in that circuit, while another circuit may uphold the same regulation. For a client with operations in several states, the memo should identify which circuit's law would apply to an appeal and whether that circuit has spoken. Your suggestion to monitor new circuit decisions closely is well taken, since the next few years will produce many of them. A citator check before every memo is now essential.

Reply to Daniel

Daniel, you asked whether revenue rulings lose authority now that regulations no longer receive Chevron deference. Revenue rulings were never entitled to the same deference as regulations. Courts have generally treated them as the IRS's litigating position, entitled at most to respect according to their persuasiveness. Sawyers and Gill (2018) describe them as the IRS's official interpretation of how the law applies to a set of facts, binding on the IRS but not on courts, which have long treated them as persuasive rather than controlling. Schnee and Seago (2012) discuss how courts applied different levels of deference to different Treasury pronouncements, with regulations at the top and less formal guidance below. Loper Bright therefore narrows the gap between regulations and revenue rulings from the top rather than lowering rulings further. Both now depend on how persuasive a court finds them. For research memos, the practical point is that a revenue ruling remains useful evidence of the IRS's position and of how an examiner will view the facts, and following one generally protects a taxpayer against penalties, but it is not a substitute for analysis of the statute itself. I would add a citator check to see whether any court has rejected the ruling.
