SECTION 2. BACKGROUND
Internal Revenue Bulletin 2004-33 · 2026-10-03 edition · updated 2026-10-04 · United States
Section 1361(b)(3)(B) of the Internal Revenue Code allows an S corporation to elect to treat a domestic corporation that is not an ineligible corporation (as defined in § 1361(b)(2)) as a QSub if 100 percent of the stock of the corporation is held by the S corporation. Under § 1361(b)(3)(A), a QSub is not treated as a separate corporation and all assets, liabilities, and items of income, deduction, and credit of a QSub are treated as assets, liabilities, and such items (as the case may be) of the S corporation.
Section 1.1361–3(a) of the Income Tax Regulations generally provides the time and manner of making a QSub election. An S corporation makes a QSub election for an eligible subsidiary by filing a Form 8869, Qualified Subchapter S Subsidiary Election, with the applicable service center. Under § 1.1361–3(a)(4), a QSub election cannot be effective more than 2 months and 15 days prior to the date of filing, and cannot be effective more than 12 months after the date of filing. Situation 2 of Rev. Rul. 2004–85, published in this Internal Revenue Bulletin, concludes that an election to treat a subsidiary as a QSub terminates if the S corporation transfers 100 percent of the QSub stock (whether by sale or reorganization under § 368(a)(1)(A), (C), or (D)), to another S corporation in a transaction that does not qualify as a reorganization under §368(a)(1)(F). In the interest of sound tax administration, the Treasury Department
and the Internal Revenue Service believe that a simplified procedure for requesting relief for a late QSub election following a QSub termination as a result of transaction described in Situation 2 of Rev. Rul. 2004–85 is appropriate.
