The Chevron doctrine has often drawn the attention of conservative lawmakers and jurists. This well-established principle extends to federal agencies the privilege to interpret ambiguous laws and attribute these interpretations a sizeable amount of deference. A case currently under Supreme Court review, Loper Bright Enterprises v. Raimondo, may however, threaten the continuity of this doctrine.
Any modification or dismissal of the Chevron doctrine would lead to notable repercussions on tax regulations and practices. In the absence of the conceded deferential standard, courts will no longer be required to recognize IRS regulations as authoritative interpretations of vague laws.
Stuffing these interpretive gaps with regulations, IRS and Treasury Department maneuver their way through intricate real-world transactions and tax law ambiguities. The reconsideration and legal contesting of matters could lead to a generational shift in tax law—resulting in substantive loss of tax revenue.
The bulk of the policy-related work is carried out through copious pages of regulations propagated under the Internal Revenue Code Section 482. These regulations enable multinational enterprises to apportion income and expenses across distinct tax jurisdictions. The IRS has developed complex regulation frameworks for price setting and allocations, thereby preventing potential tax evasion or avoidance through price manipulation.
If the Supreme Court were to overturn Chevron, all such standards would be open to judicial review, generating immediate uncertainty in international tax practices. Multinational firms might need to evaluate the extent to which they can rely on existing IRS guidelines for their tax planning, which could potentially impede cross-border trade until such a time that this uncertainty is resolved.
Greater involvement of the judiciary would likely result in an increased variability in tax law understanding. Instead of one regulatory voice, the tax authority would be broken down, resulting in a patchwork of case law that compounds tax planning and compliance complexities for taxpayers.
To guide tax policy without any judicial involvement in a post-Chevron world, clear and unambiguous statutes are needed. The death of Chevron would necessitate a significant transformation in tax law; it acts as either a warning of an immediate shift or the first clear signal that change is on the horizon. It is, therefore, an alarm bell for preparedness.
The entire discussion above is framed within the ongoing case of Loper Bright Enterprises v. Raimondo.
