SECTION 3. SIGNIFICANT CHANGES

Internal Revenue Bulletin 2006-45 · 2026-10-03 edition · updated 2026-10-04 · United States

Significant changes to Rev. Proc. 2002–37 made by this revenue procedure include:

.01 Sections 4.01(2), 4.01(3), and 4.01(4) of Rev. Proc. 2002–37 are removed from the applicability section and are reinserted, where appropriate, in the relevant inapplicability subsections under section 4.02 of this revenue procedure.

.02 Section 4.02(2) of this revenue procedure removes section 4.02(2)(b) of Rev. Proc. 2002–37 because the entities formerly described by section 4.02(2)(b) of Rev. Proc. 2002–37 are included in section 4.02(2)(a) of this revenue procedure.

.03 Section 4.02(2)(e) of this revenue procedure provides that an interest in a pass-through entity that does not have a required taxable year is disregarded solely for purposes of section 4.02(2). Thus, having an interest in a pass-through entity that does not have a required taxable year does not make a corporation ineligible for use of this revenue procedure.

.04 Section 4.02(5) of this revenue procedure excludes from the scope an S or terminated S corporation. See Rev. Proc. 2006–46, 2006–45 I.R.B. 859, for procedures to follow for certain automatic changes in the annual accounting period of an S corporation.

.05 Section 4.02(8) of this revenue procedure excludes from the scope certain controlled foreign corporations (CFCs).
