Indian Tribal Government Plans

Law stated as of October 3, 2026 · Governmental, Church, and Tribal Plans

Scope and status

Tribal benefit plans sit at the intersection of three bodies of law — the Internal Revenue Code, ERISA, and federal Indian law — and the governing tax guidance has been in transitional relief since 2006 with no final regulation. This is the least settled area in the Desk Reference. Arizona has twenty-two federally recognized tribes, many operating both governmental programs and substantial commercial enterprises, so the governmental/commercial split in A2 below is the recurring analytical problem. The general governmental-plan analysis is in this Part's Governmental Plans; read that file's §414(d) units first, because the tribal rule is an overlay on it. For 403(b) substance, see Part 8 (403(b) Plans), qualified-plan testing to Part 5 (Qualified Plan Testing, Eligibility, and Vesting), and welfare/ACA to those Parts.

Sections

The opening sections of Part A are shown in full. The other sections are listed by title; their text is available to subscribers.

Part A — Governmental Plan Status Under §414(d)

A1.Tribes were added to §414(d) only in 2006

Part 20, ch. 3, § A1

Before the Pension Protection Act, §414(d) reached the United States, States, political subdivisions, and their agencies and instrumentalities — tribes were not included, so a tribal plan could not be a governmental plan. PPA §906 amended both Code §414(d) and ERISA §3(32) to include a plan established and maintained by an Indian tribal government, a subdivision of one, or an agency or instrumentality of either — but only if all of the plan's participants are employees substantially all of whose services are in the performance of essential governmental functions but not in the performance of commercial activities (whether or not those activities are an essential government function). Statute: Code §414(d); ERISA §3(32); PPA §906 (effective for any year beginning on or after Aug. 17, 2006). IRS Notice 2006-89, §III.B; Notice 2007-67.

A2.The essential-governmental-function / commercial-activity split

Part 20, ch. 3, § A2

The distinction is drawn at the level of the employee's services, not the employer's character or the use of the revenue. Guidance and the Joint Committee's technical explanation identify casinos, hotels, service stations, convenience stores, and marinas as commercial activities. Statute: Code §414(d); IRS Notice 2006-89; IRS Notice 2007-67; legislative history — Joint Committee technical explanation to PPA §906.

A3.The structural consequence — two plans, not one

Part 20, ch. 3, § A3

Because the test is all-or-nothing at the plan level (subject only to the frozen-benefit transition rule in A1), the standard structure is two separate plans: a §414(d) governmental plan for employees performing essential governmental functions, and a separate, ERISA-covered, fully Code-compliant plan for commercial-enterprise employees. Statute: Code §414(d); IRS Notices 2006-89 and 2007-67 (addressing mixed plans).
