Mirror Code Boundaries and Substantive Regulations: An Analysis of Perkins v. Virgin Islands Bureau of Internal Revenue
Perkins v. Director of the Virgin Islands Bureau of Internal Revenue, No. 3:25-cv-00002 (D.V.I. Sept. 18, 2026)
Territorial tax administration frequently presents complex jurisdictional and statutory coordination questions under the “mirror code” framework. In Perkins v. Director of the Virgin Islands Bureau of Internal Revenue, the District Court of the Virgin Islands directly addressed whether the Virgin Islands Bureau of Internal Revenue (VIBIR) possesses authority to assess the 3.8% Net Investment Income Tax (NIIT) under Internal Revenue Code (I.R.C.) § 1411 against a bona fide resident of the U.S. Virgin Islands (USVI).
Resolving a motion for partial judgment on the pleadings under Federal Rule of Civil Procedure 12(c), the court held that the VIBIR’s assessment was ultra vires and void as a matter of law. This decision re-anchors territorial tax enforcement to fundamental principles of federal territorial power, administrative law, and binding Treasury regulations. For CPAs and Enrolled Agents advising high-net-worth individuals and entity structures in USVI or other mirror-code territories (such as Guam and the Commonwealth of the Northern Mariana Islands), Perkins serves as a crucial authority on the non-applicability of Chapter 2A un-mirrored taxes and the absolute binding nature of Treasury Department legislative regulations on territorial tax authorities.
